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.

Some Fun with MySQL’s History List

Why this article? First, I had fun digging in the code. Then, I was reading about the future improvements for MySQL 5.6 and about some currently in 5.5. Most of them are well covered by people with more expertise than me. So I read, but after a while I became curious, read the code, and performed tests. I was looking at how the new Purge thread mechanism work and its implications. Here’s what I found.

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.

The Postgres-XC 1.0 beta release overview

When I heard about this project a year ago, I was really excited about it. Many cluster-wide projects based on Postgres were developed very slowly, based on older (i.e. Postgres-R http://www.postgres-r.org/) or proprietary (i.e. Greenplum) versions. The features that this project hoped to achieve were ambitious, as we’ll detail in this post. And best of…

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.

New versions of PgPool released – 3.1.3 & 3.0.7

This essential tool for Postgres architectures is continually improving, and is now available in its new releases. Both are bugfix versions. For those unfamiliar with the tool, it is a middleware with functionality as a load balancer, pooler*  and/or replication system for PostgreSQL databases. The 3.1.x versions are compatible with Postgres 9.x, whose streaming replication…
