Why ALL Tools in at Your Disposal ARE IMPORTANT

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 […]

Application Performance Monitoring- First View

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, […]

Oracle Open World 2015, Survival of the Fittest!

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 […]

Be the Change You Want to See

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 […]



New Python Pass the Pigs Game

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 […]


Oracle Open World and Oak Table World Schedule!

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 […]

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 […]

Adding Music to Code On Your Raspberry Pi

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 […]



Recommendations to Address Cloud Performance Issues via EM12c

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 […]


Submit an Abstract to RMOUG Training Days 2016!

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 […]


Updating the Raspberry Pi Vbox Image

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 […]

Raspberry Pi Controlled Airplane Launcher

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 […]


Creating a Trace File from EM12

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 […]

Enhancing A Moving Art Project to Beginning Robotics with Raspberry Pi

Back on August 7th, the RMOUG’s Quarterly Education Workshop, I walked everyone through using a Pibrella board to create an art or flyer project that was powered with a python script and a motor. Today, we’re going to take that same code and reuse it with a simple robotics kit to control power and rotation […]



Python Pass the Pigs

So I don’t doubt that many parents are bleeding out money for kid’s school fees, supplies, clothing and other demands this time of year.  How many of you are in their local Target, Walmart or other store and after filling the cart with the necessary, the kids eye up the toy aisle and start to […]



The Evolution of a Programmer and the Pythonic Way of Thinking

There’s an old joke about the evolution of a programmer. It starts with the programmer in their infancy and typing: Print “Hello World” and so the output returns: The programmer continues to evolve. His coding knowledge increases and his code in the end of his evolution becomes a script of 5000 to 10,000 lines. What […]
