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?

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.

What a Difference a Space Makes

I had a very interesting experience in my “RACing up the Miles” session this morning. There were about 70 people in the room, and I hope they enjoyed the session as much as I did. I discussed a wee bit of architecture about RAC and concentrated on a very basic beginner’s primer to management activities with srvctl and crsctl.

And They’re Off….

It’s day 2 of COLLABORATE, and I have no distractions like hockey to tend with today. I have seen a nice balance between new technology and the traditional offerings in the Oracle tech space. These user group shows, in some ways, are the bastion of the technologies which, as “old” as they may be, are still in use and of interest to many attendees.

Day 1 COLLABORATE12

Ah yes, the comfort of being around my second family: the user group and fellow Pythianites. I started my day with a BIG DATA session by Ian Abramson. I have heard quite a buzz about this topic for some time, and it’s getting louder. I always love to hear about the multi-terabyte data structures/databases as it reminds me of the first time I went from a 20Mb to a 40Mb hard disk on an 8086.
