Sorry to late reply

I was busy to test many senario and gathering information to find the cuse of problem.

and the result is as follow :

Senario 1- Whenever we restart the DB2 the result of execution time is same(7 min ) and each stream took same cpu%(3-4) and job will finished fine.
Please note that in this case related table space GBP not allocated and the job dived between to memeber via WLM.

For example : Member 1 ( Job1 - Job2 - job3 - job4) and Member2(job5-job6-job7-job8)

Scenario 2- In the second run without changing any thing with same setuation some of the jobs not taking CPU%( less than 1%) and some Taking 3-4 %. The jobs which taking CPU%(3-4%) will finished fine(7 Min )and the jobs which taking CPU% less than 1% taking time more than 30 Min.
Please note that in this senario WLM will divided defferent stream on the Members and related table space GBP will allocated.

Member1 ( job5 - job2 - job6 -job4)
Member2 (Job3 - job7 - job1 - job8)

Senario 3-Restart DB2 again and separate the strem between Members by SYSAFF. In this case everything will fine and jobs will taking expected CPU(3-4%) and execution time (7 Min) for each run.

We took accounting report but its to much complicate and to much data .

Please help me to which point of accounting report I should focus?

Senario 4- Bing up both DB2 in One Member again everything is fine.

Best regards
Manshadi
