Use this command to determine how long TSM saves records in the recovery log and what kind of database recovery you can use. You cannot change the log mode during a database backup.
Privilege Class
To issue this command, you must have system privilege or unrestricted storage privilege.
Syntax
>>-Set LOGMode-+- Normal------+-------------------------------->< '- Rollforward-'
Parameters
In NORMAL mode, you cannot use a database backup trigger.
In ROLLFORWARD mode, you can use the database backup trigger. If the trigger is defined when you change to ROLLFORWARD mode, TSM immediately runs a full backup. If the trigger is not defined, your next database backup must be a full backup. If you attempt an incremental backup, the operation fails.
Examples
Task
Change the log mode from roll-forward to normal.
