Performance control

Database calls from the program units can only be recorded for the IUTMDB interface and not for to XA databases such as Oracle.

To control the performance of the UTM application, the UTM event monitor KDCMON can be implemented with the formatting tool KDCEVAL. Some of the lists formatted with KDCEVAL also contain database-specific information:

• The TASKS list contains the proportion of time spent on DB calls in the database column.

• The KCOP list specifies how often DB measurement data was written in NOOP.

• The TACLIST list specifies the number of DB calls for each TAC.

• The TRACE and TRACE2 lists are trace lists containing both the UTM calls and DB calls.

More details on KDCMON and the associated evaluation lists can be found in the section“KDCMON - UTM event monitor”
