Hi

I'm using CA insight to monitor threads. I have a job whic is running for a very long time.query being used is fine. Now there in the response time, there is a row 'Other DB2 Time' which shows that it is here that most of the time is consumed. Can someone let me know, what the reasons accountable for this?

Hello,

One reason may be the process is waiting on something in use.

The query may not be fine if it processes to many rows or tries to acquire a high number of locks. . .

you're welcome.
The article is just two days old.
Pure coincidence that it answers the question so clearly. (or is mailsaurabh.tripathi Dave Beulke in disguise?)

Hello,

Something less than elegant you might try - is to run the problem process at a time when there is no other DB2 activity (possibly in the early a.m. on a weekend).

If the process runs acceptably when it runs alone, then the search is on for the processes that interfere with it. Keep in mind that it is probably interefering with other processes as well.

If the process still has the same problem, it is time to look at the query(ies) or the database definitions.
