Transaction Detail Trace view (ITADTRAC)

The Transaction Detail Trace view (ITADTRAC) provides a detail trace of IMS, Db2, and MQSeries events that occurred as a transaction was processed.

The content of each trace entry depends on the type of event that is displayed. The entries are either from the online trace storage buffer or, if the request specified logging, from the trace log data set. You can use this display to analyze complex IMS performance problems associated with the execution of specific transactions. The details also indicate whether control data was provided for the ICAL.

For detailed information about the fields on ITADTRAC, press your Help key or enter HELP on the COMMAND line.

If a detail trace is active for a transaction, you can access ITADTRAC for a transaction instance by:

  • Issuing the DT line command beside the transaction instance in the Trace Summary view (ITASUM) or the Region Activity view (IRGNSUMR)
  • Selecting the Detail Trace option on the Transaction Summary Data view (ITASTRAC)
  • Selecting the Detail Trace Display option from the IRGNMR Region Menu

If ITADTRAC was initiated from the IRGNSUMR view or the IRGNMR menu for an in-progress unit of work, the trace sequence number field (Seq#/Rgn) contains the region number, and the Trace ID field shows ACTIVE. For a BMP region, the Tran and User/LTERM fields will have no value, and the Arrived field will contain zeros.
