long processing time but why?

Posted on Jan 09, 2007 at 12:43 PM 162 Views

Hi all .......

in TCode STAD "SAP WorkLoad: Single Statistical Records - Details".

some time or many times I found that, processing time is 10 time of cpu time.

and there no bottleneck in CPU its always free and also Roll wait time.

So can some one tell me where the long waiting time come from?

Thank you

    Hi,

    SAP note 8963 eplains the definition of the processing time. And SAP note 99584 explains why a very large processing time might appear in STAD.

    If a long running dialog step performs many DB operations then an overflow in the DB statistic may occur. Reason: a 4-byte counter for microseconds will wrap around after approx. 71 minutes. Then the measured DB time is very small compared to the response time. This is the reason why a very large processing time is shown.

    Maybe this explains your situation. It has been solved with SAP_BASIS 700 where larger counters have been implemented.

    I hope this information helps.

    Kind Regards,

    Andreas

      Hi ben

      Actually I don’t have problem in my system.

      But when I check STAD "SAP WorkLoad: Single Statistical Records - Details".

      Some record shows long processing time maybe 10 times longer than CPU time.

      CPU always free. And no roll wait time, so why it shows long process time with out processing much because CPU time is so less.

      Thank you very much
