Latest Delphix Blog Post and Upcoming Webinars

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.

Installation of Rundeck with the Ansible plugin on Centos 7

This post shows you how to install Rundeck with the Ansible plugin on Centos 7. The installation is done with nginx as the web server and using SSL with a self signed certificate. Please read the Ansible installation script, and modify anything that should be different for your situation. You will be amazed how well readable the installation script is!

Rundeck is a web based user interface that allows you to run commands against a group of hosts. Rundeck has an ansible plugin. Using that plugin, it could perform the similar functionality as Ansible Tower (commercial product) or Semaphore (open source).

After a fresh installation of Centos 7, do the following as root:

The $50 Million Hyphen

There are a plethora of mishaps in the early space program to prove the need for DevOps, but Fifty-five years ago this month, there was one in particular that is often used as an example for all.  This simple human error almost ended the whole American space program and it serves as a strong example of why DevOps is essential as agile speeds up the development cycle.  

DevOps and Webinars- July 19th and July 25th

Doing three or four webinars in a month doesn’t seem like a big deal until you actually try to do it…and present at two or three events and make sure you do everything for your job outside of that, too.  Suddenly you find yourself scrambling to keep up, but I’m known for taking on a few too many things at once… </p />

DevOps is Ruining the DBA?

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.

Ara: ansible run analysis

This is a short blogpost meant as both an introduction for those who don’t know Ara and a guide on how to install Ara.
Ara means ‘Ansible Runtime Analysis’, and is a tool for storing metadata that Ansible uses during execution. It is very valuable, because it takes a lot of guesswork and entering debug statements in your playbook away.

This is a guide on how to install Ara on Oracle Linux 7. I assume ansible is already installed. If want to start fresh, add EPEL and yum install ansible and git. That’s all you need to begin!

First, become root and install ara using a playbook:

Its All About the DevOps Roll of the Dice

Different combination in the game of tech create a winning roll of the dice and other times create a loss.  Better communication between teams can offer a better opportunity to deter from holes in development cycle tools, especially when DevOps is the solution you’re striving for.

DevOps and Source Control

The topic of DevOps and and Agile are everywhere, but how often do you hear Source Control thrown into the mix?  Not so much in public, but behind the closed doors of technical and development meetings when Agile is in place, it’s a common theme.  When source control isn’t part of the combination, havoc ensues and a lot of DBAs working nights on production with broken hearts.

Do You Even TDM, (Test Data Management)?

Along with the deep learning I’ve been allowed to do about data virtualization, I’ve learned a great deal about Test Data Management.  Since doing so, I’ve started to do some informal surveys of the DBAs I run into and ask them, “How do you get data to your testers so that they can perform tests?”  “How do you deliver code to different environments?”
