Upgrade Exadata to 11.2.0.3

I’ve recently done two Exadata upgrades to 11.2.0.3 and want to share the experience. I hope this short note will help someone to make the decision, calculate an estimation, and prepare for maintenance. I am going to talk about upgrade from the version 11.2.0.2 BP10 to 11.2.0.3 BP2.

Oracle Database Appliance as a Consolidation Platform

I had the chance to talk to several Oracle Database Appliance users at the annual Collaborate 2012 conference last month in Las Vegas. A common theme in these discussions, as well as discussions with Pythian clients, is an interest in using the ODA as a large-scale consolidation platform. I found this interesting and decided to dig a little further.

Hardware Component Failures – Survey Results

When preparing for the the IOUG Collaborate 12′s deep dive on deploying Oracle Databases for High Availability, I wanted to provide some feedback on which hardware components are failing most and least frequently. I believe I have a reasonably good idea of the answer, but I thought that providing some more objective data would be better. I couldn’t find results from a more scientific research, so I decided to organize a poll. This blog post shows the results, which I promised to share with several groups.

Two Database Engines, One Table

Our flagship tool, Support Track, is steadily migrating over to use DBIx::Class to read and manipulate our databases. This is a very useful tool, for many reasons that can be better explained by others. One of these reasons is that, thanks to the magic of SQLite, it lets us write unit test scripts, and other quick prototyping codes, without needing to set up a heavy database server to run against. However, Support Track is powered by Oracle, not SQLite, and while DBIx::Class abstracts most of the differences out of our code, it can’t completely eliminate them. How do we overcome the syntactic differences?

Collaborate 2012 as Seen by a MySQL DBA

I spent last week at Collaborate 2012 in Las Vegas, and it was a really great experience in many ways. I am a MySQL DBA and have been working with MySQL for most of my career, so Collaborate didn’t seem like an obvious choice. It turned out that I had so much to learn from Oracle professionals and the Oracle community that could be applied in the MySQL world. For me, an indication of a good conference is when you come back inspired and full of ideas.

Around the World in a Day: Oracle Apps Upgrades the Pythian Way

Pythian’s Oracle Apps DBA team recently upgraded a client’s E-Business Suite system to version 12.1.3, bringing them into compliance with Oracle’s baseline support requirements for Release 12.1 nearly one year ahead of deadline. We’d like to tell you a bit about this project — not to toot our own horn (though that’s nice too, we are kinda proud), but because it provides an ideal illustration of the power of the Pythian service delivery model, particularly as it applies to large enterprise-class projects.

Elaborate on COLLABORATE

COLLABORATE is all about quality and content, presenters elaborating based on their specific areas(s) or expertise. The show may be elaborate, but “show” is secondary to education. A handful of tier 1 shows throughout the calendar year do just that. The primary focus is on the user community, the people who live the software from day-to-day.

YACR! (Yet Another Conference Review!)

I made the epic journey with my Pythian (and former Nokia) colleague Andrew Moore, and once at the conference we met up with more members of our Pythian MySQL team: Marco Tusa, Raj Thukral, and Singer Wang. We all ran into former colleagues at the conference, caught up with old friends, and made some new friends. The conference this year was buzzing with enthusiasm, learning, and creativity. I’m delighted to say it delivered everything I anticipated and more.

MySQLboy @ MySQL Conf 2012 [part 1/2]

The Keynote talks included some words from Peter and Baron of Percona, Martin Mickos now of Eucalyptus Systems, and Brian Aker of HP. I was impressed by the new HP cloud product powered by OpenStack and now with an Aker-driven DaaS backed by a tuned Percona Server. It was interesting to watch the demo video on creating new instances as well as the snapshots of existing instances to create cloned instances. I would like to review this for myself and now will since the HP guys were offering to send beta access to the attendees.
