About message logs

OLAP Services sends information to several log files to help you monitor operations and troubleshoot any problems.

You can view the following logs through Instance Manager:

• OLAP Service. Check this log if you are having trouble starting OLAP Services or if it stops unexpectedly. It contains a list of events with times and descriptions. The following I/O Management parameters affect this log:
  • EventLogPath. Identifies the path where OLAPEvent.log is written. Each OLAP service must have its own unique log path.

  • OverWriteEventLog. Controls whether OLAPEvent.log is cleared when a service restarts or whether it retains all of the information from startup to shutdown from previous executions of the service.

  • SeparateXCAEventLog. Controls whether XCA events are written to this log or a separate log file.

  The OLAP Service log is stored in a text file named OLAPService.log.

• OLAP Service Agent. This log records information that pertains to communications between the OLAP service and Instance Manager. This information is stored in a text file named OLAPServicesAgent.log

You can use a text editor or other utility to view the following additional logs:

• Instance Manager log. Check this log if you are having trouble running Instance Manager. Messages concerning startup and operation of Instance Manager are stored in a file named osim.log in the log directory of Oracle home.

• XCA log. Check this log if you are unable to connect to OLAP Services using OLAP Worksheet. Diagnostic information about XCA is stored in a file named OES_XCA_Event.log in the olap\log directory of Oracle home when the SeparateXCAEventLog parameter (located on the I/O Management sheet) is set to YES.
