Anyone who says developers and DBAs can’t work together is wrong; it is vital that we work together. In many ways we share job roles and responsibilities, DevOps or no DevOps. These articles are developer-centric, or at the least feature important information for the DBA as it pertains to the development role.
Real Push Button Refresh with Raspberry Pi
In this post, we’re going to perform a push button refresh of an Oracle Database, Application Express (APEX) installation, and Tomcat webserver. “But Oracle Alchemist,” you’re probably thinking, “we know about that. You’ve told us about how Delphix can provision and refresh data.” And yes, you’d be right. But I
Deploying Application Express with Delphix
Seamless cloning of an application stack is an outstanding goal. Seamless cloning of an application stack including the full production database, application server, and webserver in a few minutes with next to zero disk space used or configuration required is the best goal since Alexander Graham Bell decided he wanted
Another Great OpenWorld
Last week I attended Oracle OpenWorld 2014, and it was an outstanding event filled with great people, awesome sessions, and a few outstanding notable experiences.

IT Stockholm Syndrome
Random thoughts on a Friday afternoon… We’ve all got problems. More to the point, every IT department or team has problems of some kind. It’s why we hire consultants, buy products, start long and arduous journeys into the great unknown depths of root cause analysis, and so on. What fascinates
The Delphix Alchemist?
Alchemists are best known for their (completely fictional and entirely ridiculous, but that’s besides the point) amazing ability to turn lead into gold. Let’s face it, there’s a lot of lead in the Oracle world. Bugs, angry developers, metrics that can seem to elude human understanding…but I digress. The question
The High Price of Data
You’ve purchased servers, storage space, switches, cables, and countless other pieces of hardware. The Oracle licenses are bought and paid for, Enterprise Edition with a few add-ons. All told, you’ve spent a small fortune on this infrastructure. It’s finally time to start up your database and begin using it for
Hadoop Streaming, Hue, Oozie Workflows, and Hive
MapReduce with Hadoop Streaming in bash – Bonus! To conclude my three part series on writing MapReduce jobs with shell script for use with Hadoop Streaming, I’ve decided to throw together a video tutorial on running the jobs we’ve created in Oozie, a workflow editor for Hadoop that allows jobs
