So this week I’m back on the other coast, Raleigh, NC at ECO17 after last week in Seattle. I’ve switched from SQL Server to Oracle and we won’t discuss how many times I had to correct myself as I said, “transaction log” instead of “archive log” and pointed west instead of east for the ocean…My expression at times was similar to Obi Wan’s- For the next month, I’ll be sticking to the Oracle side, as this is going to be a crazy month for travel. My two sessions at ECO this week were well attended and I really enjoyed talking…

This week I had the opportunity to present at Microsoft’s Pass Summit, which was one of two events I had on my list for this year, (the other was Oracle Open World.) Although I’m still learning about all the events on the Microsoft side, unlike Oracle, where there’s one, massive event in San Francisco each fall, Microsoft has split their annual events into three to focus on each audience. In less than two months, there was MS Ignite in Florida, focused on tomorrow’s technology, IT Dev Connections, geared towards development and then this week, Pass Summit, for the Data Platform…

I travel and a seriously good amount. I will present at about 35-40 events, attend company functions/meetings and this year with a considerable amount of those outside of the Denver area, this means I’ll be on a plane around 5-6 trips per month. Women commonly pack more, but I receive a few comments per my average three day trip on how I’m able to travel with a 16 inch carry-on. I’m picking up new tricks every day, but the one thing I’ve come to learn, once you find a great travel trick, you have a tendency to look no further…

The network has often been viewed as “no man’s land” for the DBA- Our tools may identify network latency, but rarely does it go into any details, designating the network outside our jurisdiction. As we work through data gravity, i.e. the weight of data, the pull of applications, services, etc. to data sources, we have to inspect what connects it to the data and slows it down. Yes, the network. We can’t begin to investigate the network without spending some time on Shannon’s law, also known as Shannon-Hartley Theorem. The equation relates to the maximum capacity (transmission bit rate) that…

It was a really busy summer and ended with me returning after a week of vacation in Singapore. What should I do after a 17hr flight and jet lag? Two webinars and a SQL Saturday event! What better way to get over jet lag and get my game back on and just jump back in! I started out by having a webinar this morning on “DBA to DevOps to DataOps- the Revolution.” I had a feeling with the jet lag, I’d be done faster than I’d hoped, but with the amount of questions from the over 400 attendees, it was…

Data gravity and the friction it causes within the development cycle is an incredibly obvious problem in my eyes. Data gravity suffers from the Von Newmann Bottleneck. It’s a basic limitation on how fast computers can be. Pretty simple, but states that the speed of where data resides and where it’s processed is the limiting factor in computing speed. OLAP, DSS and VLDB DBAs are constantly in battle with this challenge. How much data is being consumed in a process, how much must be brought from disk and will the processing required to create the results end up “spilling” to…

In my latest blog post on the Delphix site, I continue my conversation with why DevOps is the next step for DBAs and how DBAs can embrace this next step in their evolution. This is an extensive series of blog posts, (four so far) to be followed by an ebook, a podcast and two webinars. One is to be announced soon from Oracle called, “The DBA Diaries” and the other will be a from Delphix, titled, “The Revolution: From Databases and DevOps to DataOps“. The goal for all of this is to ease transition for the Database community as the…

After returning from KSCOPE two weeks ago, I was again approached to be a judge this year on the Geekathon 2017. I was thrilled when the option was left open to me to compete this year. instead of be a judge. As much as I love to offer my insight and expertise in a judging capacity, I really do love a great maker opportunity, which I haven’t had much time to allocate to with all the work I’m doing at Delphix. Needless to say, I’m looking forward to this year’s competition, so look out maker’s, there’s a new…err, old gun….old…

Database Administrators, (DBAs) through their own self-promotion, will tell you they’re the smartest people in the room and being such, will avoid buzzwords that create cataclysmic shifts in technology as DevOps has. One of our main role is to maintain consistent availability, which is always threatened by change and DevOps opposes this with a focus on methodologies like agile, continuous delivery and lean development. Residing a step or more behind bleeding edge has never phased the DBA. We were the cool kids by being retro, those refusing to fall for the latest trend or the coolest new feature, knowing that…

I know you’ve read the title and are thinking, “Great, I’m going to learn how to write better presentations!” The truth is, it’s about how conferences do call for papers timelines, abstracts, as well as how we manage our content. Timing Is Everything In recent years, there’s been a scramble to get on the schedule for the best speakers. I remember when I first started as the director for RMOUG’s annual Training Days conference. I had to keep the opening date for Call For Papers, (CFP) secret, since the moment I opened the portal up, IOUG, ODTUG and UKOUG were sure…

I know that right sidebar on my blog has an AWFUL lot of Microsoft events on it. There’s so many, I’ve begun to use the hashtag #MySummerOfSQL due to it. For those of you that follow me with Oracle, it doesn’t mean that I’m leaving the Oracle community- not even close. I’m as dedicated as ever to Oracle and hope to dig back into my performance roots on both platforms, but know that the summer is the quiet time for Oracle user group events, so I’ll be keeping myself busy with SQL Saturdays and the AWESOME preview to the annual…

I just returned from a week in Paris and it was fantastic! No amount of terrorist attack could hinder my enthusiasm for the week of vacation and although Tim and I were unaware a man with a hammer at Notre Dame would garner so much attention from the news outlets, I realized quick enough that I was in a slew of online, video and print as the major American tourist who witnessed…well, a person lying wounded on the pavement with police over him, guns drawn. I also became quickly alerted that there was a massive crowd coming towards me looking…

Happy National Goth Day! Although I consider myself “Goth Lite”, it’s a national holiday in my little world and I’m pondering what books I’ll write after I run out of tech titles. Needless to say, I’ve chosen the title, “Staying Geeky and Goth After 50” and chosen the following for the cover art: I’m considering adding a black choker to Ma Goth and maybe some facial piercings to Pa- we’ll see. As May winds down, I look forward to a vacation in Paris the beginning of June with my favorite person, Tim Gorman. As much as we travel together, we…

After looking at my upcoming schedule for 2017, I realized that I need to start posting on where and what conference(s) I’m at regularly. With that realization, I present “Where in the World is Goth Girl” posts that will help keep track of me, (before my husband has a homing device surgically implanted in my brain….:)) This week I’m in Manhattan for Data Summit 2017, presenting on Wednesday on Database Virtualization. As soon as I’m done presenting on Wednesday, I’m heading to the airport to fly to Cleveland for the second day of NEOOUG, Great Lakes Oracle Conference, (GLOC) 2017…

I was in a COE, (Center of Excellence) meeting yesterday and someone asked me, “Kellyn, is your blog correct? Are you really speaking at a Blockchain event??” Yeah, I’m all over the technical map these days and you know what? I love the variety of technology, the diversity of attendance and the differences in how the conferences are managed. Now that last one might seem odd and you might think that they’d all be similar, but its surprising how different they really are. Getting to Know You Today I’m going to talk about an aspect of conferences that’s very near to my heart,…

How many times have you had a developer come to you and say, “I just did a bad thing in the database. Can you recover from what I just did?” With Delphix virtualization, we make this pretty easy to address from the user interface with a simple slider to recover from a PIT before the catastrophic mistake, but today, we’ll discuss how to do this from the command line 1.Log into the Delphix engine as an admin user. ssh delphix_admin@<yourengine> delphix > timeflow delphix timeflow > ls 2. Depending on the platform that you’re using, (in our example, we’ll use…

I ended up speaking at two events this last week. Now if timezones and flights weren’t enough to confuse someone, I was speaking at both an Oracle AND a SQL Server event- yeah, that’s how I roll these days. Utah Oracle User Group, (UTOUG) I arrived last Sunday in Salt Lake, which is just a slightly milder weather and more conservative version of Colorado, to speak at UTOUG’s Spring Training Days Conference. I love this location and the weather was remarkable, but even with the warm temps, skiing was still only a 1/2 hour drive from the city. Many of…

There are a lot of people and companies starting to push the same old myth regarding the death of the database administrator role in companies. On the Oracle side, it started with release Oracle 7 and now is proposed with the introduction of cloud. Hopefully my post will help ease the mind of those out there with concerns. There are a number of OBVIOUS reasons this is simply not true, but I’m going to write a few posts over the next year on some of the less obvious ones that will ensure DBAs stay employed for the long haul. The…
