It is considerably more difficult to locate the causes of user-oriented performance problems than to investigate system-oriented performance problems (using SM2).
If response or dwell times are unsatisfactory for certain users, it is necessary to interpret the task-specific measurement values as well as to assess the global workload values.
In addition, SM2 user task measurement should be performed:
/START-TASK-MEASUREMENT allows users or systems support to specify tasks which they want to have monitored.
Besides task-specific measured values, program counter statistics and SVC statistics can also be requested. The measured values are written to a user-specific file and analyzed by the software product SM2-PA (see the “SM2-PA” manual [30 (Related publications)]).
