To delete alerts immediately, that is, during your current online TSO session, enter Y in the Immediate delete of alerts field. Press Enter.
To define the lifetime for particular alert states in days, place the cursor in the Day Until Deleted column and enter the maximum number of days that an alert with this state should be kept. You can use this delete option in addition to the use of the TSO online delete process. The lifetime definitions are used the next time job APCBJREO is executed to reorganize the database.
To disable the delete process for a specific alert state, enter a lifetime value of 999.
