I’m thrilled to see the outpouring of support for EM13c already out with it just being announced on Friday! As technologists all over the world jump in and start installing the newest and greatest version of Enterprise Manager, there is a second group already working on the task of upgrading their existing EM12c environments, (seen a few already, including one from Gokhan!) Along with other requirements, like setting optimizer_adaptive_features set to false, there is pre-requisite that I’d like to recommend that everyone perform on any EM12c environment before endeavoring on an upgrade- do a health check with EM Diagnostics. Enterprise…

SQL Monitor is one cool tool. Via EM12c, it empowers everyone, (yes, that means the developer, too, so give them the access to view this data via Cloud Control, please!) This is a top five list, but it doesn’t stop there, just remember, this is my favorite features when using Cloud Control with SQL Monitoring. Once logged into the database, you can gain access to SQL Monitor by clicking on Performance –> SQL Monitoring. 1. High Level View The main view of active and inactive processing, (just remember, SQL Monitor processes will age out, so keep that in mind that this…

After my AWR Warehouse session at DOAG in Nuremberg, Germany last week, an attendee asked me if he really needed to use trace files anymore with the value provided by AWR, (Automatic Workload Repository) and ASH, (Active Session History.) I responded that trace files were incredibly valuable and should never be discounted. To use an analogy, when I was 22 years old, and entered a doctor’s office missing a small percentage of my visual field after an apparent migraine, doctors used a number of different “tools” at their disposal in an attempt to diagnose what had happened. They first started…

Working with test data is always fun and teaches those of us inside Oracle how best to use the new products that will be offered to benefit customers. To me, it’s pretty straight forward and I didn’t first understand why it was necessary, but as I sit in on calls as we do performance testing of these great, new products, I understand why they need to direct so many, so often. Anything performance is as much a mindset as it is a science. Application Performance Monitor, aka APM, is no different. I didn’t exactly “follow” the hands on labs each time we’ve been…

This Saturday I’ll be part of a nationwide event being put on by the Raspberry Pi Organization and Barnes and Noble book stores. Makers Faire’s have been gaining international attention as the place to see really cool tech and inventions “in the wild” by everyday people making a difference. Barnes and Noble Maker’s Faire Event I’ll be presenting at my local Westminster, CO store and am really looking forward to the event. I was approached by Matt Richardson from the Raspberry Pi organization to participate and I was really honored to be picked to be part of this. The event…

So I’m about to depart for one day in San Antonio, Tx. to present at the International Performance and Capacity Conference, but I wanted to try to get another blog post out, this time regarding my survival at the 2015 Oracle Open World. I’m not sure if it just that the schedule was a month later than usual or that it was just more demanding this year, but I left on Friday, feeling utterly exhausted and judging by the tweets and posts from others on social media, I don’t think I was the only one! I always regret what I didn’t…

This is one of about 40 blog posts I’ve been eagerly awaiting for permission to post on the Oracle Management Cloud, (OMC)! There are three main products that will be offered initially through the Oracle Management Cloud– Application Performance Monitoring, (APM) Log Analytics IT Analytics This post will focus on one area of the third offering of IT Analytics– Database Performance Analytics. How can advanced IT Analytics investigate database performance at the cloud level vs. on premise? We’ll take a look deeper into this Oracle Management Cloud feature today and hopefully give you just a taste of this incredible upcoming suite…

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…

So in honor of coaching a Python introduction class with Devoxx4Kids this weekend, I thought I would update my pass the pigs game and add in the scoring and just rewrite it a little. If you aren’t familiar with this fun little game, here’s the gist- It consists of two pigs that you roll like dice. Depending on how the pigs land, you get a particular score- I’ve simplified my original script even a bit more and added a function to set up the roll. I’ve added the scoring in, along with information on if you roll doubles and the…

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! 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…

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,…

So as I prepare for next week, coaching with some other great folks with the Oracle Education Foundation using the Raspberry Pi, I wanted to add some fun music into my code to work with our motor mascot project. To do so, you need a few things: A small speaker with a 3.5 plugin to the Raspberry Pi. I have a small, round, rechargeable one that I love. Have an FM radio station that streams music that you can use in your code. Install and use music libraries If you haven’t done so recently, run an update on your Rpi: sudo…

So I’m going to start this post with an admission- I don’t have access to a cloud environment to test this out, but I know what I would do first if I experienced slow response time on database creation or cloning via EM12c to the cloud and I would like to at LEAST post what I would do to give others the chance to test it out and see if it offers them some help. Knowing what is causing slow performance is essential to trouble shooting any problem. I’ve had a few folks come to me with complaints that their hybrid…

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…

So one of the things I like to do is test out a lot of my python gaming code, (as far as for the coding and syntax) on my Oracle Virtualbox image of my Raspberry Pi. Another great thing about building games on the Raspberry Pi, is a built in module called Pygame. Well, that doesn’t exist on the Raspberry Pi image and it really limits what we can do when it comes to the VNC build we play on the Oracle Virtualbox, (that’s a mouthful… :)) Get Outside Access The first step is to first get out to all…

Everything I do with the Raspberry Pi is about finding ways to incorporate STEAM, (Science, Technology, Engineering, Art and Math) into my projects. This is no easy feat, but I have a lot of fun while I try. This latest project, we’re still working on ways to “enhance” and understand how code can be used with multiple projects and to satisfy multiple requirements. Science Kit Projects, to the Nth Level Our first project used DC motors to make an art project or spinner turn at the appropriate rotation required. I then was able to repurpose this same code to bypass…

Creating a trace file from EM12c is quite easy and doesn’t require a DBA offering up the world to allow a developer or support person to perform this action. Enterprise Manager also removes some of the syntax options that could get a developer or app support person that is less specialized in creating trace files, all the options and the knowledge of the syntax, etc. from getting into trouble, which creates an option for everyone to be successful. The proposed solution that I’ll post here is where the EM12c user will be able to create trace files, but the DBA will control the…
