Breaking Things, Buffer Busy Waits, Siebel Analytics and the SAN, Some HOTSOS Freebies

Backup and Recovery

Here's a nice article over at the Momen Blog on how to break Oracle so you can practice fixing it. The reader will find out the fine art of corrupting a block in order to then work on how to fix corruptions.

Buffer Busy Waits and Siebel Analytics

One of our clients recently encountered some performance problems, and one of the symptoms was high buffer busy waits with timeouts. In researching it I came upon this article, which has some very good back and forth on the issues involved.

Also from the Oracle Sponge blog is this article on Siebel analytics and some of the difficulties that can come from SANs set to default to OLTP optimization rather than those of a warehouse.


Did you miss Hotsos this year? Bummer. It's an awesome Oracle performance conference. But you can get the slides from Tanel Poder's Hotsos presentations at his blog here.
