Error description
The archive log size estimation used to decide when a database backup is needed can be refined. The current estimation just monitors the entire file system utilisation. When it reaches 80% a database backup is triggered to be able to reclaim space. This estimation could be adapted in case the file system is big. In that case, even if the file system reaches 80% (for example if the file system is filled by other data) there could still plenty of room for the archive logs. Another symptom would be that frequent database backups are triggered automatically. For example, if the archive log directory resides on a file system or drive that is 400GB in size, a database backup will be triggered if there is less than 80GB of free space. Those repeated database backups may cause an excessive amount of scratch tapes to be used. Tivoli Storage Manager Versions Affected:6.x all platforms Initial Impact: Low Additional Keywords: archive log, dbbackup, database, trigger, automatic
Local fix
The recommendation is to use a dedicated file system for the archive logs. If this is not possible, add the following option to the server options file : ARCHLOGUSEDTHRESHOLD XX The default value is : ARCHLOGUSEDTHRESHOLD 80 In the the case where the file system has a large amount of free space, increase the value to prevent the trigger of frequent db backups. For example : ARCHLOGUSEDTHRESHOLD 90
