This trending feature can be very useful in determining the impact of tuning measures. For instance, if the database in the above example were moved to a less active DASD volume, you might want to repeat the trending plot to see if the percentage of time spent waiting for the database is reduced.

IMS ID selection (SYSID keyword)

EPILOG requires that you have only one system collecting into any given EPILOG datastore (EDS) at any one time. Normally this means that all records in your EPILOG datastore will be stamped with the same IMS ID. However, there is nothing wrong with having records with different IMS IDs in the same datastore; this happens whenever you change your systems IMS ID.

By default EPILOG ignores the IMS ID stamped in a record and treats all the records in an EPILOG datastore as if they originated from the same system.

You can tell EPILOG to display only records with a certain IMS ID by adding the SYSID keyword to any display request:

DISPLAY GRP(2) SYSID(A083)
