Always Check Your Backups
So this is a 2 node RAC cluster on RHEL that was recently upgraded from 10.2.0.2 to 10.2.0.4. Since then clusterware restarts crs every few hours (8 in fact). A little research suggests that this can indicate problems with the automated OCR backup. The first thing therefore is to check the state of the backups.
[server] $ORA_CRS_HOME/bin/ocrconfig -showbackup
server 2006/10/25 11:21:23 /u01/crs/oracle/product/10.2/crs01/cdata/cluster_name
server 2006/10/25 07:21:22 /u01/crs/oracle/product/10.2/crs01/cdata/cluster_name
server 2006/10/25 03:21:20 /u01/crs/oracle/product/10.2/crs01/cdata/cluster_name
server 2006/10/24 03:21:13 /u01/crs/oracle/product/10.2/crs01/cdata/cluster_name

yes that’s right nearly 3 1/2 years since a successful ocr backup. When did you last check yours.
