Messages in the BRMS log become less useful as they age. BRMS provides two methods for removing aged messages for the BRMS log.
The first method uses the Remove log entries (RMVLOGE) parameter on the Start Maintenance for BRM (STRMNTBRM) command to specify the type and date range of messages to be removed. The default behavior of this parameter is to remove all messages older than 90 days. The STRMNTBRM command provides the easiest method to maintain the BRMS log since this is a command that you should be running frequently.

F24=More keys The alternative method for removing BRMS log messages is to regularly schedule the Remove Log Entries from BRM (RMVLOGEBRM) command. You might consider using this command if you want to run BRMS log maintenance independently from BRMS maintenance, or on a different schedule. In this case, you would specify *NONE for the RMVLOGE parameter on the STRMNTBRM command.
