DL/I-Call-Summary report

One DL/I-Call-Summary report is produced each time the DB Monitor is run, and the report describes times by PCB name and type of DL/I call.

The DL/I-Call-Summary report tells two things:

• How long IMS was inactive (no IMS code was being executed) because IMS was waiting for use of a resource or for completion of an event. This time is called IWAIT time and, for all practical purposes, can be considered the time IMS had to wait while an I/O operation took place.
• Of the elapsed time during which IMS was inactive, how much of it was actually IWAIT time.

All times in the DL/I-Call-Summary report are in microseconds. A microsecond is one millionth of a second (in other words, 7050 microseconds equals 0.007050 seconds).
