Node Panic During Initialization of Sun Cluster Support for Oracle Parallel Server/Real Application Clusters

If a fatal problem occurs during the initialization of Sun Cluster Support for Oracle Parallel Server/Real Application Clusters, the node panics with an error message similar to the following error message:

panic[cpu0]/thread=40037e60: Failfast: Aborting because "ucmmd" died 30 seconds ago

To determine the cause of the problem, examine the system messages file. The most common causes of this problem are as follows:

• The license for VERITAS Volume Manager (VxVM) is missing or has expired.

• The ORCLudlm package that contains the Oracle UDLM is not installed.

• The amount of shared memory is insufficient to enable the Oracle UDLM to start.

• The version of the Oracle UDLM is incompatible with the version of Sun Cluster Support for Oracle Parallel Server/Real Application Clusters.

• A reconfiguration step has timed out.

To correct the problem, perform the appropriate recovery action for the cause of the problem and reboot the node that panicked.
