RAC Post Deployment Fixes and Patches
This section provides the required fixes and patch information for deploying Oracle RAC 10g.
Reconfiguring the CSS Miscount for Proper EMC PowerPath Failover
When an HBA, switch, or EMC Storage Processor (SP) failure occurs, the total PowerPath failover time
to an alternate device may exceed 105 seconds. The default CSS disk time-out for Oracle 10g R2 version
10.2.0.1 is 60 seconds. To ensure that the PowerPath failover procedure functions correctly, increase the
CSS time-out to 120 seconds.
For more information, see Oracle Metalink Note 294430.1 on the Oracle Metalink website at
metalink.oracle.com.
To increase the CSS time-out:
1
Shut down the database and CRS on all nodes except on one node.
2 On the running node, log in as user root and type:
crsctl set css misscount 120
3 Reboot all nodes for the CSS setting to take effect.
