Detecting database processing intent conflicts

The IMS Monitor records the intervals when a region is in an idle state waiting to update a database owned exclusively by another already scheduled application program.

You can see the total, maximum, and average idle times in IDLE FOR INTENT following the DL/I calls. The elapsed time during the unsuccessful scheduling of a program in that region is included in the summary line times for that region.

The region can fail to be scheduled even when ownership of that database is released. The number of times processing is held up by intent failure is separately tallied under the title INTENT FAILURE SUMMARY. The report is illustrated in the following example. In this report you can see which PSBs are in conflict because of exclusive intent for a segment type and the database name in question.
