LOG_RETAINFILES
Specifies the number of log files to keep. The default is 5. The current log file is named SYSTEM.LOG. As each new log file is created, 1 is added to the serial numbers of all the earlier logs, for example, SYSTEM_002.LOG becomes SYSTEM_003.LOG, the existing SYSTEM.LOG is renamed to SYSTEM_001.LOG and the new log is named SYSTEM.LOG. Once the limit has been reached, the oldest log is discarded each time a new one is created.
Editing this option would required a MGR system restart to take effect.
