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 analogy, when I was 22 years old, and entered a doctor’s office missing a small percentage of my visual (more...)

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, new products, I understand why they need to direct so many, so often.  Anything performance is as much (more...)

Barnes and Noble Maker’s Faire- Raspberry Pi Power, Activate!

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 (more...)

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 than usual or that it was just more demanding this year, but I left on Friday, feeling utterly exhausted (more...)

IT Analytics- Global Database Performance

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 (more...)

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 Kevin, was a great opportunity to talk about something that is very important to folks like Jeremy Harms (more...)

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 dice.  Depending on how the pigs land, you get a particular score-


I’ve simplified my original script even a bit (more...)

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 with customers and speak at Oak Table World!


Per Steve Karam, if you need to know who’s speaking and (more...)

Indianapolis, ECO, IOUG and Oracle Education Foundation, Ohm My!

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 (more...)

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:

  1.  A small speaker with a 3.5 plugin to the Raspberry Pi.  I have a small, round, rechargeable one that I love.
  2. Have an FM radio station that streams (more...)

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 I would do to give others the chance to test it out and see if it offers them some (more...)

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 where it is now and how I stayed in touch with the man who is now my partner (more...)

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 doesn’t exist on the Raspberry Pi image and it really limits what we can do when it comes to the (more...)

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 with multiple projects and to satisfy multiple requirements.

Science Kit Projects, to the Nth Level

Our first project used DC (more...)

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 the options and the knowledge of the syntax, etc. from getting into trouble, which creates an option for everyone to be successful.


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 speeds/time to the Insectoid.  This kit, puchased from the Go! store in Flat Irons Crossing mall, was $16 and can (more...)

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 ask for something?

Even teens are not immune and may be asking for games.  If you could turn (more...)

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 does the output return? You guessed it:


I often joked that I’d make a terrible developer. I over think everything, (more...)
