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.
The directory /var/opt/SUNWscor/oracle_server/proxyresource contains log files for the resource that represents the Oracle 10g Release 2 or 11g RAC proxy server. Messages for server-side components and client-side components of the proxy server resource are written to separate files:
Messages for server-side components are written to the file message_log.resource.
Messages for client-side components are written to the file message_log.client.resource.
In these file names and directory names, resource is the name of the resource that represents the Oracle RAC server component.
The directory /var/opt/SUNWscor/oracle_server contains log files for the Oracle 9i RAC server resource. Each file is named /var/opt/SUNWscor/oracle_server/message_log.resource.
The system messages file also contains diagnostic information.
If a problem occurs with Sun Cluster Support for Oracle RAC, consult these files to obtain information about the cause of the problem.
