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.

My First Experience Running SLOB – Status Update 2 (first results)

I think the results we got so far may surprise you. At lease they don’t seem to be the results +Alex Gorbachev and +Kevin Closson expected to see. You can find the first related blog post here. It will give you the necessary context for further reading. Just to recap: +Kevin Closson says that “Orion may give It’s VERY easy to get huge Orion nums but reasonable SLOB” and +Alex Gorbachev says that “lots of the system IO bound below the CPU level so you should see similar number with Orion or SLOB”. Let’s see what the first results revealed.

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.

Storage Replication for Oracle Database and Licensing

While doing my high availability deep dive at Collaborate 12 few weeks ago, I stated that storage replication qualifies for the cold failover licensing rules (see slide #128). During collaborate, I spoke to one person at Oracle who definitely knows the rules. Simon Haslam also reached out to me by email pointing out that things might not be that rosy. I will update the slides accordingly. In any case, please do your own homework and don’t trust my conclusions here — don’t take this as licensing advice by any means.

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?

Log Buffer #270, A Carnival of the Vanities for DBAs

As Summer begins in many parts of the world, not only is nature waking up, but many bloggers are also coming out of hiatus and the database blogsphere is seeing new sensational activity. This Log Buffer Edition includes blogging tidbits from Oracle, SQL Server, and MySQL. Enjoy!

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.
