Welcome to Log Buffer, the weekly news blog about blogs in the datasphere… As we kick off Log Buffer #206, our own Gwen Shapira shares a few of her weekly favorites:


Arup Nanda posted an excellent script on how to summarize backup information from the rman catalog. He also posted a tool for automatically purging time-based partitions.

Pythian’s resident Exadata expert, Marc Fielding posted links to the latest recording of his Exadata webinars.

Gary Mayers, on Sydney Oracle Lab explains Oracle user security model.

Riyaj Shamsudeen shows what really happens when you update a query with the same values it already had.

Jonathan Lewis explains how he tests list partitions, a post which gives an excellent review on how one should go about testing new features in general.


At MySQL Performance Blog, Aurimas posts a war story about a very unusual data recovery. Test your backups, or you may have to go through the same ordeal.

In same blog, Morgan Tucker gives another reason why you shouldn’t use mysqldump to take backups.

SQL Server:
MVP Edwin Sarmiento is blogging live from SQL PASS 2010 in Seattle.

Aaron Bertrand introduces a feature in SQL Server 2011, called SEQUENCE that most Oracle DBAs would recognize too.

And lastly a few general posts. One from Michael Lopp, who, on the “Rands in Repose” blog, explains how people follow conversations, with some amusing examples.

And the second from Singer Wang who reports that RedHat 6 is finally out after 4 years.

A big shout out to this week’s contributors wraps up this issue. Don’t forget, if you’re interested in hosting your own issue of Log Buffer – send an email to the Log Buffer Coordinator.
