Logs consume disk space on Essbase Server. If you have Administrator permissions, you can delete logs from Essbase Server. For more information, see the Oracle Essbase Database Administrator's Guide.
Before you delete a log from the Essbase Server, consider copying the log to a different location as a backup. An Essbase Server log is stored in the MIDDLEWARE_HOMEuser_projects/epmsystem1/diagnostics/logs/essbase/instance directory and is named ESSBASE.LOG. An application log is stored in the application directory (for example, MIDDLEWARE_HOMEuser_projects/epmsystem1/diagnostics/logs/essbase/instance/appname) and is named appname.log.
To delete a log:
From Enterprise View or a custom view, select an Essbase Server or an application.
Right-click and select Delete, then Log.
Click OK.
If log chart information exists for the log, you are prompted to delete that information from the Log Analyzer database.
