Universal Messaging provides automatic log file rolling. This means when the size of the log file reaches a certain threshold, the server closes the current log file and opens a new one. The maximum size for a log file is set to 100,000,000 bytes (approximately 100 MB) by default. This value can be changed by modifying the -DLOGSIZE property in the Server_Common.conf file under <InstallDir>/UniversalMessaging/server/ directory. You can also change this via Enterprise Manager's "Config" panel in the "Logging Config" group. The 'DefaultLogSize' property specifies the default size of the log in bytes.

Depending on the log level set and the level of activity, these logs files can grow quite large and occupy considerable amounts of disk space. It is recommend to archive and clean up the old journal log files periodically.

Depending on what is being logged to the audit file, the file can grow quite large. As it is an audit and provides historical data, there is no automatic maintenance of the file. It is up to the realm administrators on when the file is archived. The 'Archive Audit' button in the Audit panel of the Enterprise Manager rolls the audit log file by renaming the existing audit file to a name with the current date and starts a new audit file. It is recommend to archive and clean up the archived audit log files periodically.
