Node Panic Caused by a Timeout

The timing out of any step in the reconfiguration of Sun Cluster Support for Oracle RAC causes the node on which the timeout occurred to panic.

To prevent reconfiguration steps from timing out, tune the timeouts that depend on your cluster configuration. For more information, see Guidelines for Setting Timeouts.

If a reconfiguration step times out, use the Sun Cluster maintenance commands to increase the value of the extension property that specifies the timeout for the step. For more information, see Appendix C, Sun Cluster Support for Oracle RAC Extension Properties.

After you have increased the value of the extension property, bring online the RAC framework resource group on the node that panicked.
