Hello,

Which problem(s) are you trying to address?

Why did you run Strobe in the first place?

The job is taking more time so we have started tuning cics db2 vsam cobol.
The strobe report its pointing below places

DB2 DSNGEDM DSNGEPLC LOC SKPT SEC IN DASD/EDM - 11%
NUCLEUS IEATTUSD SUPERVISOR SERVICES - 4%
LELIB CEECCICS CEEVGTSI GET A STACK INCREMENT 3%
NUCLEUS IEAVELK SPIN LOCK SERVICE - 2%
DB2 DSNBBM DSNB1GET RETRIEVE REQUESTED PAGE - 2%
DB2 DSNXGRDS DSNXECW RDS AGENT LOCL NOTIFICTN - 2%

So . I need reduce CPU consume time .. Please let me know any idea .

For example
The below strobe report ,CPU consuming is 11% its pointing in DB2.
DB2 DSNGEDM DSNGEPLC LOC SKPT SEC IN DASD/EDM - 11%
Please let me know Any idea to tune this DB2 tunning or Do we need to use any parameter in Db2

More time than what? How was the determination that this is "too long"?

If this is cics, which "job"(s) are taking too long?

Are you referring to "wall time"/response time?

One "problem" with looking at database cpu time is that when more cpu% is used it is often because the data was already in the buffer and did not need to be physically read from disk (which would make the run even slower, but may reduce the cpu%).

Have you checked with your cics support (if this is actually a cics issue) about how much load is on the cics region(s)?

Thanks for the Help!! Please find the my response

More time than what? How was the determination that this is "too long"?
We are finding High MIps consuming jobs(we are analysing only TOp 50 Jobs) with help of SAS program.

this is cics, which "job"(s) are taking too long?
This region job

Are you referring to "wall time"/response time?
I don't know How to do check "wall time"/response time

My strobe report is pointing the below

DB2 DSNGEDM DSNGEPLC LOC SKPT SEC IN DASD/EDM - 11%

so I need to know DSNGEDM( what is this) .. Why strobe is pointing..
then Is there any possible way to tune this job?

Hello,

For EDM (environmental descriptor manager) look here:

Quote:

This region job
What is "this region job"?

Quote:

Do you mean jobs or cics transactions within one region?

Quote:

Wall time/response time is the time on the clock on the wall (or a wristwatch). It is the least scientific measurement, but often the most visable - people really notice the wait. . .

As has been mentioned before, nothing you posted indicates a performance problem. . .
