Viewing audit history of processed segments

Select option 4. View audit history of processed segments to view a trace of all the segments of a database that you viewed while you navigated through the database.

About this task

This feature is available only from the time when IMS Database Repair Facility is invoked for a selected database until it is re-invoked and option 2. View/Update database is again selected for that database. At that point, the history file is reallocated.

Procedure

Select option 4. View audit history of processed segments in the Main menu and press Enter.

In the Select IMS system panel, select the IMS system ID that is associated with the history of segments that you want to review by entering an S in the input field that corresponds to the IMS system ID. Then, press Enter.

In the Specify database panel, specify the database name or, for a partitioned database, the master DBD name in the DBD name field. Then, press Enter.

If you specify the master DBD name of a partitioned database, the Partition Selection List panel is displayed. Select a partition in the panel by entering an S for the partition. Then, press Enter.

Review the history of processed segments in the Audit history of processed segments panel. This panel includes the RBAs of all segments that were accessed while you navigated through the database. Additional information is also shown to help you identify the segment and how it was accessed during IMS Database Repair Facility run.

The segment that was most recently accessed is shown at the top of the list. Identifying information about the segments is provided under the Time heading.
