Transaction Summary Data view (ITASTRAC)
| For more information, view the Quick Course 'Managing IMS traces'. |
You can use the display (shown in Transaction Summary Data view (ITASTRAC)), for example, to see how many times a transaction instance accessed a database, the types of calls it made and how many, and the transaction elapsed time. An unusually high elapsed transaction time might indicate poor DASD response time.
The ITASTRAC view provides a CALL OVERVIEW section that show call statistics and includes DL/I and ESS DL/I metrics.
For information about the any of the sections and fields in ITASTRAC, use the H line command on the section header. If a detail trace is active for the transaction, use the D primary command to access the Transaction Detail Trace view (ITADTRAC).
By using the Prev Seq Num and Next Seq Num fields, you can browse through the transaction records. You can also select a specific record for viewing by entering the sequence number in the Seq Num field.
You can access the ITASTRAC view with the S line command in the Trace Summary view (ITASUM).
