Sources of Diagnostic Information

If the state of a scalable device group resource or a file-system mount-point resource changes, the new state is logged through the syslog(3C) function.

The directories /var/cluster/ucmm and /var/cluster/vucmm contain the sources of diagnostic information that are shown in the following table.

Source
Location
Log files for previous multiple-owner volume-manager reconfigurations
/var/cluster/vucmm/vucmm_reconf.log.0 (0,1,…)
Log file for the current userland cluster membership monitor (UCMM) reconfiguration
/var/cluster/ucmm/ucmm_reconf.log
Log files for previous UCMM reconfigurations
/var/cluster/ucmm/ucmm_reconf.log.0 (0,1,…)

The directory /var/opt/SUNWscor/oracle_server/proxyresource contains log files for the resource that represents the Oracle RAC proxy server. Messages for server-side components and client-side components of the proxy server resource are written to separate files:

In these file names and directory names, resource is the name of the resource that represents the Oracle RAC server component.

The system messages file also contains diagnostic information.

If a problem occurs with Support for Oracle RAC, consult these files to obtain information about the cause of the problem.
