I attend five sessions today and I think some of them were very interesting. Like the one on the Optimizer insight, quite informative and accurate.
It is exciting to be here, meeting again old friends and ex colleagues, but also exciting for what seems the start of a very significant conference fro MySQL. I really enjoy the introductions done from Edward Screven and Thomas Ulin. Edward highlight the fact that MySQL is increasing his presence in the market and in the community.

At Oracle Open World 2012, RAC SIG personnel will be on-hand running RAC Attack – a hands-on lab where you can build a cluster on your Windows, MAC, or Linux personal computer. This is a dream come true. I first did RAC Attack at the UKOUG show in Birmingham last December.

Recently, we had a situation where a customer asked us to move Master Database from Local Drive to SAN drive. I have outlined the steps for the task.
Oracle OpenWorld 2012 is just over a month away and yes we are organizing the Annual Oracle Bloggers Meetup — one of your top favorite events of the OpenWorld.
This post is to discuss the Microsoft Planning and Assessment (MAP) toolkit, which is a nice little tool with a few extremely useful features.
n the business world, a good RDMS is one that can provide high availability (HA) options with minimal downtime and the cheapest licenses. Vendors usually if not always provide a set of HA features to satisfy different needs. Usually, some of these features are reserved for higher-end editions. The most important factors to consider when choosing an edition are…
The traditional NoCOUG SQL challenge has been launched this year with a twist: In the wake of the “BigData” trend/buzz, it’s now been upgraded to a “SQL and/vs. NoSQL” challenge. I took on the challenge, treading through my SQL comfort zone and thinking of ways I could bend relational algebra to solve the wicked puzzle suggested this year.
