High CPU consumption in VSAM Record Management due to COBPACK-OS ESMS

Hi all,

While trying to tune  Batch Jobs / Cobol Programs using Strobe , I
came across this . Strobe Profile / Report shows Most CPU consuming
Procedure as VSAM RECORD MANAGEMENT. While the Attribution Table for
VSAM RECORD MANAGEMENT shows COBPACK-OS ESMS as the function which
causes much of the CPU consumption.This function  alone consumes as
high as 50% of CPU utilization. I would like to more about this
function. Can anyone help me ?

Regards,

VSAM tuning is a "big deal" in the IBM mainframe world.  There are lots of
papers on it and you may want to use the IBM-MAIN list for "hints and tips" 
-
but without more information, I doubt they will be able to help you.
