What are the Activity Log, Events and Summary Table.  

The Activity Log is the message log for TSM. Everything that is logged in TSM goes into the activity log. The Events Table stores information about anything that is running from the internal TSM Scheduler including admin tasks and client backups.   The Summary log is a summary of all activity that happens on the server such as admin tasks ( expiration, reclamation etc ), backups and restores.   These TSM object are stored in the TSM Database so changing any retention values will affect the size of TSM database so keep an eye out of the database utilization when increasing these values.   To change the retention values for these objects in TSM Studio, right click on the TSM Server in the TSM Server navigation windows and select Server Properties

Goto the logging tab and simply choose the new retention values for the Activity Log, Event  and Summary Tables. The values are measured in units of days
