I’ve been going through some SERIOUS training in just over a week.  This training has successfully navigated the “Three I’s”, as in its been Interesting, Interactive and Informative.  The offerings are very complete and the knowledge gained is limitless.

I’d also like to send a shout out to Steve Karam, Leighton Nelson and everyone else at Delphix who’s had a hand in designing the training, both for new employees and for the those working with our hands on labs.  I’ve had a chance to work with both and they’re just far above anything I’ve seen anywhere else.

The Challenge of Patching and Upgrades

Most DBAs know-  If you attempt to take a shortcut in patching or upgrading, either by not testing or hoping that your environments are the same without verifying, shortcuts can go very wrong, very quickly.
hardway

Patching is also one of the most TEDIOUS tasks required of DBAs. The demands on the IT infrastructure for downtime to apply quarterly PSU patches, (not including emergency security patches) to all the development, test, QA and production databases is a task I’ve never looked forward to.  Even when utilizing Enterprise Manager 12c Patch Plans with the DBLM management pack, you still had to hope that you checked compliance for all environments and prayed that your failure threshold wasn’t tripped, which means a large amount of your time would have to be allocated to address patching outside of just testing and building out patch plans.

This is Where Delphix Saves the Day

I bet most of you already knew you could virtualize your development and test from a single Delphix compressed copy, (referred to as a DSource.) create as many virtual copies, (referred to as VDBs) as your organization needs to have for development, testing, QA, backup and disaster recovery, (if you weren’t aware of this, you can thank me later… :))

What you may not know, (and what I learned this week) is that you can also do the following:

  • Test patches and upgrades on a VDB or a DSource to verify there aren’t any issues instead of doing a full, manual clone which is very time consuming.
  • Apply patches and upgrades to a DSource and the patch and/or upgrade all the VDBs attached to the DSource by simply performing/scheduling  a refresh.

Considering how much time and resources are saved by just eliminating such a large portion of time required for patching and upgrading, this is worth investing in Delphix just for this alone!

So after over two years at Oracle, I’m moving on.  Yes, for those of you who haven’t seen the tweets and the posts, you heard right.

dorothy_appaulled

OK, everyone-  cleansing breath.

I worked with great people and did some awesome things in the community, blogged everything Enterprise Manager and talked over 1/2 the Oracle community into buying and doing projects with Raspberry Pi while I was at it!

Many folks thought I was a product manager or a technical consultant, but my title was Consulting Member for the Technical Staff with the Strategic Customer Program with the Enterprise Manager and Oracle Management Cloud Group.  I know I was part of a select group at Oracle, but I believe the opportunity to work at Oracle was an important step in my career and I’d recommend it to anyone for the experience it provides.

There is a huge difference working for Oracle vs. being in the Oracle community, even as an Oracle ACE Director.  I was utterly amazed being part of the Oracle machine.  One of the most amazing experiences was observing how releases came together.   It was a complete different experience as an employee vs. a customer.  Being part of a massive undertaking such as a product release, impressively building out software to be released to its customer base is pretty astounding.  Understanding how and what it takes to move the machine and once it gets moving, how pertinent it is for anyone in its way to get out of the way is important to understanding how a successful product is created.

I learned a lot in just over two years and I have to admit-  many of the negatives that people said would be present at Oracle, I just didn’t experience.  I had great mentors and contacts inside of Oracle.  It’s easy to assimilate into a big company environment when you have people like Pete Sharman, Tyler Muth, Mary Melgaard and other’s looking out for you. I’ll be sad to leave all the great people that I worked with at Oracle, too-  Steve, Courtney, Scott, Werner, Andrew, Joe, Pramod and Will.  At the same time, I look forward to opportunities to learn new skills with the awesome folks that have so readily embraced my quirky self at my new company. I learned a great deal in my two years at Oracle and this is knowledge that I’m able to take with me as I move forward to my new adventure.

With that said, I’ve been offered an incredible opportunity to stretch my legs a bit and try something new and I am excited to move onto this new challenge.  I’ll still be speaking at conferences, but also will direct technology in a a way that should be very constructive to my technical style.

There has been a lot of rumors to where I’m off to.  Some of you have guessed correctly on where I’m going, but I know none of you guessed what I’ll be doing.  I will be focusing more on my multi-platform skills, so for those of you that thought I would be leaving all those years of experience in database and OS platforms, it’s going to be just the opposite.

I’m very excited to announce that, as of Monday, June 13th, I’m the new Technical Intelligence Manager at Delphix.

Buckle up, Baby!  This is going to be good.

I know Werner DeGruyter will like the title of this post, so here’s a post dedicated to him as my last week at Oracle is off to a busy start…. 🙂

yoda

As I attempt to wrap up any open tasks at Oracle, I’m still Training Days 2017 Conference Director for RMOUG, have a planning meeting for the 800 member Girl Geek Dinner Boulder/Denver Meetup group that I’m the owner of, designing the booth and building out all the projects for the MakerFaire event at the Denver Science Museum next weekend and now have taken on the Summer Quarterly Education Workshop at the Denver Aquarium in the end of July.  This is a bit much as I start a new job for the end of June, but there are things that need to be done for community organizations to survive and often not enough people doing it.

As I know that many other user groups are in the same boat, I come to you with pleading, open arms and say to you, as part of your community, volunteer your time.  If all of us give a little, it really adds up to a lot in the end.  As attendees at conferences, events and meetups ask what happened to this or that group and wonders why they don’t have activities any longer, it seems to always boil down to commitment from it’s volunteers.  If it’s not fed and cared for by time and care, then it won’t survive.  I have this conversation at almost every user group conference and hear similar stories from meetup groups and other event groups that you might think are no where related.  It all comes back to the passion and commitment of those involved, along with the support of those that may not be giving as much, but ensure those that are, are well cared for.

So here are the rules for the survival of a group:

  1. Everyone do a little so no one is doing too much and you end up losing those valuable resources.  I see volunteer groups and board of directors that are commonly unbalanced and that is expected-  we all have lives and demands, but if it’s always like this with no check and balances, then it’s time to for people to step up and put in some time.
  2. If you aren’t doing, you don’t complain.  If you do see something that isn’t working well and want it fixed, please be prepared to volunteer some time to help out vs. volunteering others to do the work.  That’s just flaky and do you really want to be that flaky whiner at the event? 🙂
  3. Support the people who volunteer their time to your groups and defend them within an inch of your life.  Without them you don’t have a user group, you don’t have new members, you age out and your user group dies a slow, quiet death.  If you doubt me, just look at the strewn carcasses of user groups that were once impressive specimens in the event world.
  4. There is no magic formula.  What works for one group might not work for another.  There are some very impressive individuals that are working hard to create the newest, shiniest events that attract speakers, sponsors and attendees.  This is how it always will be. The groups that have been around awhile just need to keep updating with the new and improved to stay on top of the game and compete.

RMOUG has an incredible board of directors and our volunteers are SECOND to NONE!!  This has served us well all these years.  I don’t know how I would survive the demands of Training Days if it wasn’t for the volunteers and those on the board that help me when the going gets tough.  I’m quite aware of this need in other user groups as well.

So here’s the challenge for those of you out there-  Reach out to your local user group and consider volunteering a little time to one of it’s events.

  • Help with event check in.
  • Help with setup.
  • Consider sponsorship with your company.
  • Consider helping with the board, (we have members at large on our board that is a good way to test out the waters as a board member.)
  • Look at how to become a board of director.

Ask the user group or meetup what they could use help with and DO IT.

Here is the list of regional user groups from Oracle and from IOUG.  Find yours and volunteer to your community.  It’s worth your time, valuable to your career, and it’s the only way they can continue to be successful.

I fly out tomorrow for NoCOUG’s Spring Conference, which will be held on Friday, the 13th in San Jose, California. If you were thinking of attending and needed an added incentive to attend, I’ll be putting on a FOUR hour Enterprise Manager 13c hands on lab, so admit it, you’re intrigued… 🙂

friday_13th

I want to thank Iggy Fernandez, who is the heart of NoCOUG, for contacting me and asking me to do the HOL, along with the folks from Oracle ensuring that I have the environment to offer the attendees to enjoy this great event!

I’ll fly back out of San Jose on Saturday morning and then will be flying to Cleveland on Monday morning for the Great Lakes Oracle Conference, (GLOC).  I’ll have a couple presentations on Enterprise Manager 13c and will be hosting the Women in Technology lunch area with Maria Colgan and Elke Phelps!

It should be a great event-  lots of Oracle peeps, ACE and ACE Directors, along with some Oakies.. 🙂

The conference has been growing over the last few years with the great effort of the NEOOUG and their conference support team, headed up by Linda Hoover.  I know from my work on RMOUG’s Training Days, how much goes into a conference, so when we discuss user groups like NoCOUG and NEOOUG, it’s important to support your Oracle community.  It’s the only way these communities survive is with the membership and community support.  These are two groups that are well worth the effort to ensure we continue to do so.

For those that will be at these two great events in the upcoming two weeks, see you soon!

So Uwe Hesse caught my interest when he blogged about how to add your twitter handle to your time on your taskbar.  This is really cool for those of us that present, so that while we demo, you’ll see our twitter handle displayed at all times.

I did notice that his instructions, as most instructions I find for things on the Oracle side are for older versions of Windows or for Mac.  I have a Window 10 machine and yes, it’s possible, just a few steps different.

There are a number of ways to do this….most of them are long, so I’m going to try to take you through the least amount of steps in Windows 10, which for some reason, has buried time settings… 🙂

The Easy Way

Click on the Start Window and the Auto Search Function is activated.  Type in Region.

Click on the one that has the following icon:

datetime1

Click on Additional Settings at the bottom of the Region window:

datetime3

And now you will be at the same basic Time settings as you would be in Uwe’s instructional post and can changed the displayed symbol for AM and PM to your twitter handle.

datetime2

Thank you for sharing this with us, Uwe! 🙂

Becoming a mentor was not a direct path for me.  Even though I inspired people with my perseverance and common sense, I had no inclinations for a corner office position, (I often joke about passing up the corner offices in a fight to get to the server room) and this is often a trait that is expected for someone who is titled with “Mentor.”

cusack_gpb

In the five years in an official mentoring capacity, I’ve learned as much as I feel I’ve imparted among those I’ve mentored.  I now find others asking me for advice on how to become a mentor or how to mentor more effectively and I do have some advice on that topic I’d like to share.

Becoming a Mentor

As I mentor both men and women, I can verify that each gender commonly requires different things in a mentor.  Men will often want to know WHAT they can do to attain success.  They are looking for contacts, a network of opportunities and examples they can duplicate.  The guys rarely want anything than some quick advice and definitely don’t want to talk to other men that are being mentored by me… 🙂

Women often look to me for options to overcome cultural challenges that are hindering them from reaching their full potential.  As they show ambition and attempt to make their mark, they will be faced with cultural bias that requires some careful maneuvering to successfully navigate and having not just a mentor, but a network of women who may have successful ways to work through these challenges is very beneficial.  Often times they are the only women in their department, let alone their team and to have another woman who understands the unique world we work in makes a huge difference.  Due to this, there is often small email groups, lunchs and other opportunities where the women meet each other.

Having other women to help them negotiate compensation or offers provides great value, too.  We often hear how women aren’t very good at this, but watch out if you ask a woman to review or negotiate for another woman.  I can tell you that I wouldn’t be in the position I am today without the support of my own women mentors who reviewed my own opportunities, offering their insight where I might have shorted myself.

One of the most important things a mentor needs to remember is that they are there to provide advice that is in the individual’s best interest. Its my opinion that some of the biggest waste of time is spent on people telling others how to do something that only benefits the person speaking.  If you’re mentoring because it gets you ahead, you’re doing it wrong.

Who to Mentor

This is something I’ve had to ponder quite a lot lately.  I’ve mentored a lot of people over the years- locally, nationally and internationally.  I don’t rate success on what the industry may, but on the professional satisfaction of those I mentor.  If they are happy with their career and the path they’ve chosen, then I’ve done my part.  I’ve also felt what the industry may see as some of my greatest successes, if you were to ask me, I might consider my biggest failures.  At one time, potential candidates for mentoring were those that were “hungry” for opportunities.  This often equated to ambition, but what I found is that ambition without a strong sense of self is a penchant for disaster.

With ambition and so many opportunities to make success easily reachable, success can come very quickly.  The individual you mentor must have a strong sense of self to be gracious, accept their failures without blame and to not be overwhelmed by what they’ve achieved.  They must be responsible for their own actions, do the right thing, even when it might not be the easy path.  Above all, they must be fair to others and honest with themselves.

In my long history of mentoring, I’ve only had to remove myself as the mentor to two individuals and these were painful decisions.  Both individuals have immense potential and I still believe in them and their futures.  The harm to others to achieve what they desired wasn’t worthy of who they are or the people or organizations harmed by their choices.  The most damage be their choices was to their self-esteem. They respect themselves less than they did before they approached you for mentoring.  I have wrestled with the idea that I should stick by them when they went through their first challenges with this type of situation, but found that by doing so, I only “enabled” the situation, making them often feel it was more acceptable.

These tough decisions are part of being a mentor, too.

Benefits

The biggest benefit of having a mentor, no matter if you’re a man or a woman, is that they save you valuable time by providing guidance, information and access to opportunities that you might not have been able to achieve on your own.  Our friends and family rarely even understand what we do for a living, (which is why while everyone else is enjoying the holiday meal, we’re relegated to fixing Uncle Edgar’s laptop that he ran over with his car) and so mentors in technology really do make a huge difference.

I hope other’s take this opportunity to consider reaching out to someone as a mentor or consider mentoring others.  We can accomplish so much more when we all work together.

With that, I leave you with my greatest mentor, the superhero corgi! 🙂

Since the introduction of Enterprise Manager 12c, folks have been asking for a list of best practices.  I know a lot of you have been waiting for this post!

day

1.Use previously deployed, older hardware for your Enterprise Manager deployment on 13c.

Enterprise Manager is a simple, single service system.  There is no need for adequate resources and ability to scale.  In fact, I’ll soon be posting on my blog about building an EM13c on a Raspberry Pi 3.

2. Please feel free to add new schemas, objects and ETL’s to the Oracle Management Repository, (OMR.)

This database doesn’t have enough to do with metric collections, data rollup, plugin, metric extensions and notifications.

3. Turn on the standard statistics jobs and baseline collection jobs on the OMR.

The OMR has its own version of the stats job, but running two jobs should make it run even better and even though baselines aren’t used, why not collect them, just in case?

4. Set the EM13c to autostart, but set the listener to stay down.

The Oracle Management Service, (OMS) shouldn’t require the listener to connect to the OMR when starting, after all.

5.  If there is a lot of garbage collection, just add more memory to the java heap.

If we give it more memory, then it will have less to clean up, right?  More is better and there isn’t any way to find out what it should be set to anyway.

6. If you want to use the AWR Warehouse, you should use the OMR database for the AWR repository, too.

It shouldn’t make a difference to network traffic, datapump loading or resource workloads if they share a box.  These two databases should work flawlessly on the same hardware, not to worry about network traffic, etc.

7.  If you have a lot of backlog for job processing on your EM13c, you should trim down the worker threads.

Serializing jobs always speeds up the loading of data.

8. Sizing an Enterprise Manager EM13c is a simple mathematical process, which I’ve displayed below:

math

(If I didn’t mention it earlier, there will be a quiz at the end of this post…)

9.  Never apply patches to the Enterprise Manager tiers or agents.

Each release is pristine and bugs don’t exist.  It will only require more work in the way of applying these patches and downtime to your EM13c environment.

10.  Patch any host, database or agent monitored by the Enterprise Manager manually.

Patch plans and automation of patching and provisioning is a terrible idea and the only way a DBA can assure if something is done right is if they do it manually themselves.  Who needs a good night’s sleep anyway?

Even though I didn’t have the “official” prerequisite classes of HTML and CSS for the JavaScript class offered by sister Meetup group, Girls Develop it, I decided on Friday that I wanted to take the weekend class and signed up.

The class is held at the Turing Development school and it was a great downtown location.  Very centralized, no matter if you’re North, South, East or West of the city and the venue is a school, so it’s set up with plenty of power, WiFi and projector with multiple screens.  It had started another spring time snow, so I was one of the first ones in the class that morning, but we quickly got situated-  about 25 female students all there to learn JavaScript!  I don’t think I’ve seen that many women in one technical class in my life and no matter how much I love hanging out with the guys that I do in the Oracle realm, this was a refreshing change.  The room was filled with women of all ages, all walks of life and no, I was not the only woman in the room with brightly colored streaks in her hair, tattoos or multiple piercings.

yes

Now if you haven’t already done so, I recommend joining Meetup and checking out the groups that are in your area of interest.  I run three groups, (RMOUG Women in Technology, Raspberry Pi and STEM and Girl Geek Dinners of Boulder/Denver)  I’m also part of a number of other groups, including the Big Data, Women who Code and Girls Who Develop It Meetup, which this one day class was offered by.  At $80, it was a great opportunity to dig into a new language and gain a strong introduction to a computer language, even if you didn’t have any previous experience.

Through the day, we learned how to build out a main page, test code through the console log, incorporate java script into our pages and best practices of beginning Java Script.

Now there are two things I will share with you that I feel are great tips from this class that are available to everyone.  It’s two sites for opportunities to continue with your web design/JavaScript education and they are:

  1.  CodePen–  This site demonstrates different examples of webcode, broken down between HTML, CSS and JavaScript, (any combination of 1,2 or all 3…) and you can make changes to the code to see how it impacts the outcome of the graphics and framework.  It really puts how these three interact to build out impressive web designs and where you would use one over another.
  2. Exercism–  This site gives you real world coding problems, allows you to code a solution, submit the solution for valuable feedback.  It’s important to use what you learn every day to improve upon it.  This site gives that opportunity to you.

Last night I attended our RMOUG WIT’s movie night.  We partnered with Regis and the choice in movie has received a lot of great reviews, titled, Code-  Debugging the Gender Gap.  The movie resonated with me profoundly, as I was able to connect with not just the women involved in the interviews, but the girls who reminded me of myself when I was young. There were a number of initiatives that made me proud to be part of the IT industry and opportunities still needing our contribution towards change.

Once the movie was over, we held a short WIT panel session.  I was joined by Sharisse Hawkins, Terry Morreale and hosted by Sharri Plantz-Masters from Regis.  I had way too much caffeine before being put center stage and regretted it immediately as I spoke way too much during the panel discussion.  The women who joined me on this panel had impressive credentials and I was terribly disappointed that I didn’t get to learn more about them during this short session.

The interaction with the audience was fantastic and there were a number of young women who attended that are planning on a career in technology.  I was very happy to meet many of them after the panel and impressed at their energy and intelligence.

Next time, though, I bring my time-out muzzle to keep my contributions to a controlled amount… 🙂

Thanks to everyone that attended the event and if you’re interested in future events, stay tuned to RMOUG’s website and the Girl Geek Dinner’s Meetup. We’re about to get planning under way and we’ll be having some great events for everyone to join!

I fly out on Sunday for HotSos and am looking forward to giving a joint keynote with Jeff Smith, as well as giving two brand new sessions on Enterprise Manager New Features.  IOUG’s Collaborate is just a month afterwards, so the spring conference chaos is officially under way.

hotsos16

With running the RMOUG conference, Feb. 9th-11th, I think you can imagine what my response was like when I realized how much content I had to produce for HotSos’ two sessions and then another four for Collaborate, plus a Hands on Lab.

babyscared

As focused as I’ve been on day job demands for a new product, Oracle Management Cloud, which I’m sure you’ve heard of as it goes through trials, I found myself furiously building out everything I needed for my Enterprise Manager 13c environment.  At the same time, we needed to build and test out the HOL container environment and then Brian Spendolini was kind enough to give me access to the Oracle Public Cloud to test out the new Database as a Service with Hybrid Cloud offering.

I know all of it is going to be awesome, but my brain works like a McDonalds with 256 open drive thrus, so until it comes together at the end, I’m sure it looks pretty chaotic.

mcdonalds

With that said, everything is starting to come together, first with HotSos and then with Collaborate, really well.

HotSos Symposium 2016

This will be my fourth year presenting at HotSos Symposium and where other conferences may have mixed content, this is all about performance.  It’s my favorite topic and I really get to discuss the features that I love-  AWR, ASH, EM Metrics, SQL Monitor, AWR Warehouse.  It’s all technical, all the time and I really enjoy the personal feel of the conference that the HotSos group put into it, as well as the quality of the attendees that are there with such a focused objective on what they want to learn.

That Jeff and I are going to do our keynote on Social Media at HotSos really demonstrates the importance of it’s value to a techie career.  Social Media is assumed to be natural to those that are technically fluent and to be honest, it can be a very foreign concept.  Hopefully those in attendance will gain value in professional branding and how it can further their career.

IOUG Collaborate 2016

Collaborate is another conference where I enjoy speaking at immensely.  The session attendance is high, allowing you to reach a large user base and the locations often change from year to year, offering you some place new to visit.  The venue this year is in Las Vegas at the Mandalay.  There’s so much to do during the event that its almost impossible for you to go outside or do something outside the hotel, ( can you call these monstrosities in Las Vegas just a “hotel”? :))  and I know I only went outside once back in 2014 after arriving.

collab

Joe Diemer did a great job putting together a page to locate all the great Enterprise Manager and Oracle Management Cloud content at Collaborate this year.  Make sure to bookmark this and use those links to fulfill your Collaborate scheduler so you don’t miss out on any of it!  This includes incredible presenters and I know I’ll be using it to try and see sessions for a change!

Along with my four technical sessions, I’ll be doing a great HOL with Courtney Llamas and Werner DeGruyter.  We’re updating last year’s session, (OK, we’re pretty much writing a whole new HOL…) to EM13c and we’re going to cover all the latest and coolest new features, so don’t miss out on this great pre-conference hands on lab!

Hopefully I’ll see you either this next week at HotSos or in April at Collaborate!

I’ve been feeling quite amorous about the camera features on my Samsung Galaxy 6 Edge phone, but noticed that it wasn’t taking as automatically impressive pictures as usual and sometimes, I even had to focus, (the horror!) I turned the camera over and could see a hairline crack inside the camera lens.  It was a really odd place to have damage, as the exterior cover to the lens was fine.  The camera is incredibly good, as even can be seen here in a picture that had the quality sucked out of it on Facebook from our trip to Mexico a month ago-

crab

Lovathon T-Mobile

Due to the odd crack, I brought it into T-Mobile and as wonderful as they are to their customers, (I’ve been with them for about ten years now….)  they found that the best approach was just to switch my phone out on my jump program, which also allowed me to upgrade….which also resulted in my monthly payment to go down, (nicest run-on sentence ever…:)) I had admitted to myself that I was missing my larger screen of my two previous Note phones and decided to go to the Galaxy 6 Edge +, which combined the best of both worlds in the Edge and the Note.

thumb1_

Why did I want the bigger screen?  I am just going to admit this-  I’m getting old.  I refuse to squint at a screen and try to read tiny text and the screen was just too small for the text size I preferred for comfortable reading of email, texts and such.  The 5.7″ screen on the Edge +, (1/2 inch larger than the Edge) allowed me to set the font size up to a much larger version and use the “Gothic Bold” font in a way that doesn’t overlap or wrap in a way that is not aesthetically pleasing.

The screen on the Edge series is just gorgeous.  There’s something about the Super AMOLED screen and the curved edge.  The camera just can’t seem to take a bad picture and it’s incredibly responsive to touch.

itssobeautiful

Cover It Up

Funniest thing I had to get used to was how slim it is.  I just couldn’t adjust to the first Edge’s thin profile and had to buy a robust phone case that gave the phone more weight and “substance”.  I really appreciate the cases that protect the corners and sides, but add enough to the thickness that I don’t feel like I’m about to slip between my fingers at any minute.  I’ve had great luck with Caseology and Verus combination ones that have thick rubber interiors with hard plastic shells that can be seen on mine here:

20160222_090917

And the back of the case has a nice grip to it, so you don’t have to worry about dropping it or having it slide off of a smooth surface:

20160222_090935

The Charge Pad

The last addition is the most important to my smartphone setup.  I use my phone a lot and one of the benefits of going to the Edge + was the extended battery life.  I got about 1 1/2 days on my standard Galaxy Edge.  That’s considerable vs. what most people receive in battery life, but the larger battery is a key enhancement in the Edge +.

Most people are aware that very few new phones have replaceable batteries.  We are switching out our phones more often and the new “sealed” designs protect from water damage and other issues more than the previous with a separate battery.

Even though LiOn batteries are getting more efficient with charging and have less issues than the previous ones, they can be impacted by over and continual charging.  The way to work around this is to get a charge pad for your phone and I did invest in a Black Sapphire charge pad for mine.

chrgpad

The charge pad only charges to 100% and then the QI Inductive technology goes into a sleep mode, saving from over-charge.  I don’t have to take the case off or anything, just place the phone down on it and I see a circular print across the screen and the charge signal at the upper right comes on.  The pad glows blue to tell me it’s charging and it glows green when it’s complete.

I’ve used Samsung products for quite some time now.  Everything from the Samsung Galaxy 3 Mini, (which I had to purchase out of Canada) to my Tab S2 tablet and most recent purchases discussed here.  I really love their products and nothing against Mac iphones or iPads, I just am happier with the Android OS overall and Samsung makes some seriously beautiful hardware to boot.

Now if they keep going in the direction they are with the Samsung Gear, we might be able to talk me out of my Moto360 smartwatch…. 🙂

I’m a Leaf on the Wind, Watch How I Soar.

This is one of my favorite lines from the movie Serenity.

Without Alan Tudyk’s character dying and all at the end of this, (sorry if I ruined the movie for anyone…) this is how a DBA should be in the database environment-  skilled, reliable and maybe a little off our rockers. Our job is to protect the data, the database and all of the database.

With that said, I’m going to list my Ten Rules of Database Administration.

  1. Fixing a performance problem with hardware is the best way to guarantee the return of the problem in the near future.
  2. A Database Administrator is only as good as their last backup, (or database image, clone, flashback and other redundancy.)  It’s the only protection from ID10T errors- our own and others.
  3. The best performing database is one that has no users.  The best performing query is one that doesn’t have to be executed.
  4. Optimize what annoys the user vs. what annoys you and you’ll never have to worry about your job.
  5. Never assume, always research and double-check/triple-check your findings.  Data is the savior of the DBA.
  6. Performance issues are rarely simple.  If they were simple, the user could fix them and we’d be out of a job.
  7. If a database is up and running, then something has changed.  Don’t ever accept the answer that nothing’s changed.  They’d have to be using paper and pen instead of the database.
  8. A developer’s goal is to have an application or procedure complete requirements. Your job is to make sure the code they produce does so without risk to data, database and does so efficiently.
  9. You can’t do your job as well as you can if you understand what the application developer, user and business does.
  10. The database is always guilty until proven innocent and by the way, you only have access to 1/2 the case evidence.  You’re it’s attorney-  Congratulations.

Happy Friday Folks!

I’ve just returned from another post-RMOUG conference mountain trip and happy to say that another RMOUG Training Days conference has successfully completed.  It’s a massive undertaking that takes an incredible amount of time from our board of directors, volunteers and Team YCC, our conference support company.  In the end, it’s all worth it and no one regrets the loss in personal life or family time to put on the largest Oracle regional user conference in the US.

timrmoug16

As my fourth year as conference director completes, I can look back and see how the conference has changed, how we’ve successfully taken on intriguing challenges and opportunities for improvement.

Highlights This Year

The OWL, sponsored by Oracle Technology Network.  Laura Ramsey and her folks did a great job with the Hands on Labs and events in the huge area designated behind the exhibitor area.  She had a daily schedule that was published in our mobile app and the daily highlights, which kept our attendees abreast of what was going on in the area each day.

Keynote from Carlos Sierra and Mauro Pagano.  These gentlemen have built and supported the tools that provide the deep and detailed answers that many of us in the performance arena live for.  They are also incredible people and to have them share with us what drove them to build the products, the stories behind initiatives and enhancements to where we are today was really enjoyable to listen to.  It was technical, it was personable and we enjoyed sharing it with them.

mandc

Over 100 technical sessions from the best of the best in Oracle, MySQL, OBIEE, APEX, ADF and others!  We really are very lucky here at RMOUG.  We get the best speakers in the Oracle realm-  Oracle ACEs, ACE Directors, Oracle’s technical specialists and new up and coming.  They all want to come to Denver each February to speak to Training Days attendees.

mauro

Lunches with ACEs.  This has been the third year we’ve put this on.  It’s an incredible opportunity to sit down with your Database God and get close up and discuss your technical topic of obsession.  I even got back into the game, sitting in on Ray Smith’s table, (he wasn’t able to attend, my fault, we forgot to take down his table!) and we sat and discussed Enterprise Manager features for an hour.

Women in Technology Round Table.  This went really, really well this year.  I kept the slides to a minimum and the Denver area panel did a great job discussing topics that are at the front of everyone’s minds on how to get women ahead in technology and our children’s education more focused towards tech careers.

Now the Challenge

We are going through the same challenge as any user group is going through in the US. Without the members and attendees who made the conference fantastic this year, RMOUG, a not-for-profit organization, couldn’t put on a conference next year. Here in Denver, many of our membership aren’t aware of the impressive conference they have for the incredible low cost.  Even though the early numbers are showing we had 40% new attendees, (which means my phenomenal team really did succeed in taking on this challenge) we were still down from our goals because many of our older membership didn’t attend this year’s conference.

I network with a number of user groups and user group boards.  I hear the same questions-

How do we find new attendees?

How do we grow our membership?

Our membership appears to be aging out.  How do we attract younger members?

These are the same challenges Training Days is going through and I often have discussions surrounding how to reach new demographics and attendance.  At the same time, its common to have a conversation with someone you do expect to attend that says, “I won’t be at Training Days this year…”

Our previous attendees have become accustomed that the conference will always be there the next year.  The effort that it’s taken to keep this conference active and successful is mind-blowing when I look review the data.  We make this transparent for a reason, but at this time, I think it’s important to know how our investment looks to those outside of Denver and RMOUG.

Our attendees aren’t aware that some of the top database consultant companies around the US are flying in their employees to attend RMOUG Training Days.   Our conference is 1/2 the length of Oracle Open World, KSCOPE and Collaborate, the three larger conferences in the US.  At the same time, for only 1/2 the length, it’s only a 1/5th of the cost and you get 10 tracks and 2 1/2 days of pure technical content.

The networking opportunities with the biggest companies in the US, along with your local peers is priceless!

conf16

As for RMOUG’s board and the Training Days committee?  We’ll keep introducing Training Days to new potential attendees and hope that the missing members will return to this impressive and incredible conference.   We’ll keep spreading the word to companies about how inexpensive and valuable the training is at Training Days in hopes the next generation of DBAs, Developers and Database specialists have this incredible opportunity to better themselves and their career.

If we kept this information so transparent, you, as a member or attendee of RMOUG Training Days wasn’t aware of it, start thinking of our Oracle regional user group as our community and that by contributing by attending just has the additional benefit of helping out our own career!  Now I’m going to enjoy a few weeks off before the planning starts again for next year!

There is an incredible power with the simple act of doing.  People have a tendency to complain about the world, but there are only a few that refuse to simply accept it as it is and reach out to change it.

The Gift, The Anarchy

This video with the Red Pill Analytics guys, Stewart and Kevin, was a great opportunity to talk about something that is very important to folks like Jeremy Harms, (@EmeraldCube) and I.  Jeremy is very active in the Atlanta area with his Code Crew events, introducing technology to locations that may not have the resources to offer this type of opportunity to the community.  I also wanted to introduce it to my own community a while back and started working with my own resources at RMOUG as a Special Interest Group, (SIG), partnering up with Devoxx4Kids and Raspberypi.org.  It’s incredibly rewarding as a teacher/coach/volunteer and really offers kids something they may not be able to get anywhere else.

Herding Cats and Future Technical Geniuses

I finished a great class this last Saturday, partnered up with Tuliva and Devoxx4kids.  We had a really great time and productive, too!  The kids learned about programming, development jobs and then I had them code two games, first a dice game and then Pass the Pigs, all in Python.  Of the 20+ kids, over 85% finished their games and were able to play the games themselves or with one of the other attendees!

CRiFQvWUwAAXDzL (1)

They just did a really great job and I was really thrilled with how the class did! Tuliva offered us a great venue to hold the class and their guys did a wonderful job ensuring everyone was up and running, (after we found out the Raspberry Pi’s didn’t like the VGA to HDMI converters for the monitors!)

CRiHyBAUAAEbAL_ (1)

I have no doubt that giving back and helping to focus the future of technology is what inspired Jeremy Harms of Vine City Code Crew.  Schools don’t have the resources and it’s up to us to give back and build up technology for young people in the world.

VC3

Forty-one out of fifty states in the US still don’t require technical courses to graduate from high school and of those that do, a large majority of those classes are based on Office Technology vs. logical thinking or high technology, such as basic programming classes.  One of the motivators for me was when I went to my children’s new high school and found out their pride in their multiple computer labs, all loaded with Windows 2000, how they would teach Microsoft Office programs and how to format a USB drive.  This is not technology and when I asked about programming classes, I was told they did have them in the district, but kids needed to go offsite and attend the vocational school, called Bowman.  This is both frustrating and depressing when we think that the only ones going into Tech out of high school are those that can’t make it in traditional high school.

Involvement

So how can you get involved?  There are a number of initiatives local and national you can reach out to.

  • Check Meetup to find groups local to your area that work with kids, like Girls who Code, Devoxx4Kids, Black Girls Who Code and others!
  • Join your local user groups to see if they already a STEM/STEAM program and if they don’t, see about starting one.  I knew nothing when I started mine, just figured out as I went-  trust me, genius is about 70% initiative!
  • Reach out to local schools and see if they have a computer program or even one after school that they need help with.
  • Start blogging and posting videos of projects you’re doing with your Raspberry Pi or other physical computing.  Raspberry Pi found me on Twitter and my blog and reached out to me through these forums to become part of Maker Faires to present on youth education for STEAM.
  • Ask your employer if they have any volunteer opportunities in the community for tech education.  I gained the ongoing coaching spot with Oracle Education Foundation by reaching out to Jake Kuramoto from Oracle App Labs who was aware of need for coaches with my skills.

So, reach out and be the change you want to see in the world.  If we don’t do it, who will?

So I’ll be heading out for Oracle Open World 2015 in just over another week.  This is the first year in a while that I won’t be speaking, (my own fault, as dummy here hasn’t figured out how to submit sessions internally yet, duh!)   but I’m still going to support the demo grounds, meet with customers and speak at Oak Table World!

oaktableworld2015

Per Steve Karam, if you need to know who’s speaking and why you should attend the sessions at the Children’s Museum, well here’s a few:

Jonathan Lewis – Yes. That Jonathan Lewis. Also an alien of extraordinary ability.
Tanel Poder – Doer of things you didn’t know SQL could do and the snappiest snappermaker
Alex Gorbachev – Jack of all trades, master of…well, all of them really.
Kellyn Pot’Vin-Gorman – Cloud Control control, techno wiz, and data lacquerer
Tim Gorman – Kellyn’s hype man. And world renowned Oracle expert.
Kevin Closson – Refusing to party like it’s 1999 since 1999
Gwen Shapira – A fifty petabyte machine learning datastore in human form
Cary Milsap – His advice has probably saved your database and career
Oak Table World – The best Oracle speakers outside of OpenWorld. Literally, not figuratively.

Now if that doesn’t sum it up, well, let’s be honest, there are over 60 members and more speaking that listed here, so if you have time, it’s the best “unconference”, EVER.

With that said, we’ll get back to why everyone is there in the first place and it’s because of my awesome employer, Oracle!

OOW-01

I’m busy preparing my new sessions for post Oracle Open World, which I have three conferences in November, (San Antonio, Chicago and Germany) and ensuring customers I’m in charge of for OOW preparation are ready to go when the stage lights go up!  It’s a fun kind of crazy chaos and the kind I commonly thrive under, so we’re all good!

With that said, there are a few events I’m looking forward to-

Sunday, Oct. 25th, 8:30am- Bridge Run with Crazy Oracle Peeps

Yeah, me and my arthritis will be walking that bridge, but it’s still a great event and I’ll be going.  I’m not doing the bay swim or the bike event.  Enough is enough, you crazy, exercise nuts! 🙂

Monday, Oct. 26th, 1:30pm- Managing at Hyper-Scale: Oracle Enterprise Manager as the Nerve Center of Oracle Cloud [CON9710], Moscone South–300

I have wonderful peers at Oracle and Akshai Duggal is one of them!  She’s going to be explaining how our SCP teams build out the REALLY massive Enterprise Manager environments, ensuring uptime, clear and concise monitoring, along with understanding pesky things like metrics and templates.  Check out her session with real use cases, how can you beat that?

Monday, Oct. 26th, 5pm- in the RAC Attack Area-  Enterprise Manager SIG from IOUG and Oracle.

Come meet up with all the top EM specialists in the world as we discuss the best topics surrounding Enterprise Manager and enjoy the hospitality of the OTN lounge area!

 

Monday, Oct. 26th, 6pm, the ODTUG Reception, (another invite only event…)

Another event I look forward to every year and even though I’m over booked this year, I’ll make sure to stop in for this, too!

Tuesday, Oct. 27th, 10-10:50am- Oak Table World-  Stewart Bryson and I are going to talk about OBIEE and AWR Warehouse.  Children’s Museum 

We just wanted to play around a bit and see how much trending and analysis we could do with the product and had a great time building this out.  Come check it out and then head on over for….

Tuesday, Oct. 27th, 11am-  General Session: Oracle Management Cloud—Real-Time Monitoring, Log, and IT Operations Analytics [GEN9778]  Moscone South—102

The big boss is talking, no not Larry, but my boss, Prakash Ramamurthy!  He’s going to be discussing the coolest of the cool in new stuff that I’m totally obsessed with right now and if you miss out on this session, you’re going to be missing out on the best!

Tuesday, Oct. 27th, 12:15pm, Oak Table Ted Talk!  Secret Topic! Children’s Museum

I can’t tell you what I’m going to talk about, but I’m going to tell you what I can’t tell you now.  Yeah, I really just said that… 🙂

Wednesday, Oct. 28th, 11am- Using Oracle Enterprise Manager Effectively to Become an Oracle Enterprise Manager Champion [CON9711] Moscone South 104

Courtney Llamas and a slew of great folks will be on stage talking how to become an EM Champion!

Wednesday, Oct. 28th, 4:15pm- Hybrid Cloud—Pivot to the Cloud with Oracle Enterprise Manager Cloud Control [CON9712] Moscone South 300

I really enjoy working with Steve Steltling in our SCP team and he’ll be presenting with Phillip Brown on Hybrid Cloud!

Wednesday, Oct. 28th- Bloggers Meetup from Pythian…..I’m waiting….still waiting….no invite yet….Where is it?

This is an event that I always enjoy and wait for the invite from Pythian each year, but nothing yet and will be pestering Alex Gorbachev until it shows up… 🙂

Wednesday Oct. 28th, evening- NOT GOING TO TREASURE ISLAND

Yeah, you heard that right.  Every year, even when I did get a wrist band, I gave it to someone deserving and then Tim and I enjoy the quiet city for a dinner out in ANY restaurant we like… 🙂  We just aren’t much into concerts and love the opportunity to allow someone else to go that may not have by giving them Tim’s band, (now that I’m with Oracle, I no longer get one…)

Thursday, Oct. 29th, 12pm- Oracle Management Cloud Best Practices for Mining Oracle Enterprise Manager Data [CON9714] Marriott Marquis—Salon 10/11

Werner DeGruyter, our EM Yoda and Shailesh Dwivedi are going to talk about a great topic.  I love mining Oracle EM data, so if that’s something you are impressed with, don’t miss out on this session!

If you want to see all the best of the Enterprise Manager sessions, here’s the Oracle Open World Schedule specific to EM!

Friday is the flight home, pick up my dog, DaVinci from the pet hotel and find out if my youngest son, Josh, still knows who I am!

I’ve been a bit busy traveling and speaking, but I wanted to discuss the great events I’ve been lucky enough to be part of the last couple weeks.

Indianapolis Oracle User Group

I spoke at the INOUG back on September 17th.  The user group in Indiana is incredibly welcoming and I had a great time with the wonderful attendees for my three back-to-back sessions.  We discussed AWR Warehouse, ASH and AWR Mining and a new session on Optimization for EM12c and the Hybrid Cloud.

East Coast Oracle Conference

September 21st-23rd was my first visit to the great city of Raleigh, NC and ECO!  I’ve always wanted to visit the location and had a great time not just because I got to hang out with friends like Jeff Smith, Ric Van Dyke, Kent Graziano, Scott Spendolini and Tim St. Hilaire, but I also received an incredibly warm welcome from the ECO attendees!  Linda Hoover and her team put on a great conference and the interaction from those in the sessions were phenomenal, both during and afterwards.

20150922_115657

I had a great joint keynote with Jeff Smith on “Empowering Your Technical Career with Social Media”.  It was incredibly well received and even though the room felt like it was -50F, everyone stayed for the entire keynote.  Some of the best feedback was when a woman who was working in the hotel serving food came up afterwards to tell me how much she enjoyed it and asked me some questions about what I did for a living and how to get into the tech industry.

eco_jsmith_kpotvin

An attendee also came up to me in the restaurant to let me know she’d only stayed for two keynotes her entire career and that ours was one of them!  These kind words from these two women and the other attendees who approached us meant a lot to Jeff and I.  We really appreciate the support!  I also have to thank Monty Latiolais and Ray Smith for letting Jeff and I rework their social media profiles and personal branding.  It was great to see it all come together.  For those that attended my technical session which was a deep dive in AWR and ASH, thank you for offering me a standing room only in the largest room they had at the conference and for all the interaction.

 IOUG Master Class at Sports Authority Stadium

I raced home at midnight on the 23rd to ensure I was available to do the keynote on the 24th for the IOUG Master class at….OK, let’s just say it, I’m a Denverite, it will always be Mile-High Stadium.  🙂

20150924_092558

The event included a good amount of RMOUG folks, along with some new folks and I got to speak with Graham Thornton from EMC, too!  It was a great day to be at the stadium and a great time was had by all as I spoke on Oracle Hybrid Cloud.

Oracle Education Foundation

Everyone knows I’ve been all about educating with small computers like the Raspberry Pi.  Thanks to Jake Kuramoto, I was offered the opportunity to come be part of the coaching team with the Oracle Education Foundation, specializing in teaching Raspberry Pi with Python.  I helped to build some of the content and it was an awesome experience to work with the high school kids.

20151007_143703

I only got to spend a week out of the two week project, because if I didn’t get home at least one week in October, Tim was going to come and get me!  It was a dream come true for me and I look forward to volunteering with the Oracle Education Foundation in the future.

On Thursday, Jake and his team, including the impressive Mark Vilrokx, came in to demonstrate a great nerf gun powered by an Adruino micro-computer and a sensor connected to the internet.  It used voice activated commands to shoot nerf ammo, even to know how many nerf bullets to shoot.

 

I’ll return home next week and enjoy some time with my family, my home and my dog before returning for Oracle Open World and Oak Table World for the end of October, so until then, check out the Arduino controlled nerf gun Twitter account, IOT Nerf and a shot of the great class I worked with for the week!

As the Training Days Director for Rocky Mountain Oracle User Group, one of my tasks is not just running the conference for RMOUG, but also promoting it.

RMOUG Training Days was the first conference I ever attended, (2004) and the first one I ever presented at, (2009.)  Its one of the reasons my career is where it is now and how I stayed in touch with the man who is now my partner in life, best friend and husband.

 

The Training Days conference is the largest regional Oracle User Group conference in the US and is held each year at the Colorado Convention Center with it’s unforgettable venue.

ccc_page

 

Our conference has an amazing group of volunteers and attendees, which can be seen easily just by a picture showing last year’s keynote from Maria Colgan:

rmoug15_mcolgan

With that said, currently the call for papers is open and I would like to recommend to everyone that they submit an abstract.  To prepare you for this task, let me go over a few reminders of what it takes to make a great abstract:

  1. Take the time to make a great abstract title and fill out the abstract and summary completely!
  2. Run it through spelling and grammar check.  If you submit a “sloppy” abstract with misspellings and errors in grammar, how can we know that you’ll take the time to ensure that the presentation will be performed professionally and technically accurate?
  3. List a few take-aways the attendee will leave with.  What is the value that will be gained by attending your session?
  4. Fill out your speaker biography.  We like to know a bit about you and why you are important to have presenting at the conference.
  5. No marketing!  Keep your session technical.  Our conference is a technical conference and nothing irks our attendees like marketing!  If they like what your teaching, they’ll search out your company and/or product-  trust me!

Our conference sessions selection is based off the scoring of our valuable abstract reviewers.  If you are selected to be a presenter, these are a few other things you can do to ensure that you are desired to return:

  1. If you’re on social media, find out what the twitter handle and hashtag are for the conference.  Promote it.  Many user groups have little to no marketing budget and appreciate the support.
  2. If you have a blog, find out if they can provide you a speaker button for your webpage or if they mind if you create one from their conference logo.  This is more marketing support that is greatly appreciated.
  3. While at the conference, tweet, post and share what you love about the conference.
  4. Fill out conference evaluations for both sessions you attend and the conference overall evaluation.  This lets speakers know how they did and what they can improve upon.  For conference evaluations, this data is invaluable in the next year’s planning and enhancements!

Finally, if it’s your first time submitting a paper, don’t hesitate to reach out and ask for mentoring or guidance.  Many conferences have senior speakers that can assist you and I know at RMOUG, we have a special selection process to ensure that our members get to hear from new speakers in the community.  Ensuring success of the next great presenter in the Oracle world is important to us all.  Take a deep breath and a dive into the great world of knowledge sharing!  Everyone wins when every one contributes!

Submit your abstract today!  The deadline is September 30th, 2015!

August 4th, 2015 by dbakevlar

I’ve had a lot of people email and message me asking me what I’m doing with the Raspberry Pi and I wanted to share before the actual RMOUG Quarterly Education Workshop, (QEW) this Friday at Elitches.

rmoug_summer_qew

So a little history-  When I was a kid, I was a real handful.  My mother used to come into my room and I’d have created “webs” out of yarn strung from every piece of furniture and twisted into patterns.  I used to take apart radios and use the parts to create new toys, figuring out how the electronics worked.  Dolls suddenly became cyborgs and we wont’ talk about what I used to do to poor, defenseless stuffed animals.  My destruction and “recycling” used to exhaust her to no end, but what I used to create new toys out of, rarely occurs in today’s world and when the Raspberry Pi was introduced to the stage, I was immediately smitten…:)

20150803_194756

As many know, I’m also a grand supporter of STEAM, (Science, Technology, Engineering, Art and Math) as part of the success in filling the 1.4 million open positions that we are posed to have available in technology by 2020.  That number is only going to grow and I don’t see our public education system building out core knowledge to embrace technology in a way that kids will have been introduced to logical thinking and coding to entice them to careers in technical fields.  Public educations just doesn’t have the resources or the vision to do this and I feel its up to us who are here, in the technical arena now.

steam_logo

With that said, it took some convincing to get the QEW to include a family coding event.  We were already late getting the new board in place, so we’ve been scrambling ever since!  Devoxx4Kids will be onsite and they’ll be doing a session on how to build Minecraft modules.  I’ll be teaching the Raspberry Pi session with attendees.  The project will have all areas of STEAM covered, which is quite a challenge to do in one project with kids!

The attendees will bring their Raspberry Pi setups with their parents [hopefully] in tow, and I’ll be providing small motors, pre-soldered with connectors to attach to a pibrella board that was part of the “shopping list” from the website.  The Pibrella board is a small add-on board to the Raspberry Pi that makes it easy enhance projects and it’s one of my favorite additions to my setup.  With the motor, and a small lego base, the kids will then use ART supplies to build a small project, it can be an animal, a flower, a design from stickers, even a spinner or other flyer.  The art project can be ENGINEERED any way they want, to either spin, dance or fly off the motor.

Along with art supplies, I’ll have LED lights and small watch batteries that can be used to power the lights and add to their projects.  I also have magnets to use to “attach” flyers to bases to launch which all bring in some components of SCIENCE into the project.

raspberry-pi-led-lights1

Once they finish their creation, we’ll attach it to a motor and start up our Raspberry Pi’s.  Each attendee will open up a text editor and CODE some simple timing and spinning rotations, adding different enhancements to the code, depending on what they want their project to do, (I have three coded examples that they can edit with different times, start with the execution or use the button on the pibrella to commence, etc.)

They’ll then EXECUTE their code and see if the initial TIMES COMPUTED work with their project or if they need to adjust the MATH to make the project work.

Once they are satisfied with the project they built, we’ll discuss how they might imagine to enhance their project.  Would they add lights?  Would they add music?  Might they change the physical design or code?  I want them to use their imagination and their logical thinking skills to see how cool technology can be.

20150803_192233

My youngest son, Josh, seen above, has been helping me with this project, using his master soldering skills to assist me attaching the jumper wires to the motors, helping me test out different art projects and flyers to ensure that the code works like expected and that my new [non-brand name] Lego case secures my different card installations correctly.

Thanks for listening to me rant so I can take a break from everything and hopefully, we’ll have a RAGING turn out for the family coding event, people will stick around and listen to me also ramble on about Enterprise Manager Hybrid Cloning to the Cloud and then have a great Hands on Lab using a AWR Warehouse I created for this event!

See you Friday!
