Log Transaction Analysis utility (DFSILTA0)

In an IMS DB/DC or DCCTL environment, you can use this utility to collect information about individual transactions, based on records on the system log. Many events are tabulated in the Log Analysis report produced by this utility, including total response time, time on the input queue, processing time, and time on the output queue.

You can select a start time for the report tabulation; analysis begins at the first checkpoint after the start time. To control how much transaction activity is tabulated, you can specify an interval (in minutes) of elapsed time from the start time before the utility ends the tabulation, or you can relate the activity reported to a number of IMS checkpoints.

You can retitle a Log Analysis report or change the sequence in which the detailed transaction lines are printed. You can sort by transaction code or by any of the fields in the report. You can also suppress printing so that the output is stored on a DASD data set.

Using this utility, you can create an output data set, in system log format, that is a copy of all or part of the input system logs. By having a copy of the system log, you can monitor system activity without impacting the use of the OLDS for recovery.
