Slides from MOW2010 presentation.
The presentation provides practical understanding of Oracle Clusterware/CRS and knowledge required for independent troubleshooting of Clusterware issues - why nodes are evicted, why resources don't start or fail for no reason. After the presentation, a DBA will know where to look for the answers instead of blindly running cluvfy.sh utility. The session includes demos of how to troubleshoot clusterware issues such as evictions. The presentation does goes into Oracle Clusterware internals but it's appropriate for all DBA's from beginners to experienced.
