how to increase the Performance through coding

Post by rajkamal r » Sun Aug 18, 2013 4:23 pm

Can you please help by clarify the below things related to performance?

1) We have 4 LPARs in production, When I check with my performance analyst, He had told that Z101 LPAR is hammered (heavily loaded, mostly by CICS sweeper transactions) but other LPARs are not loaded much. This scenario looks strange. Why the particular LPAR is hammered? Can you please clarify and what can be the solution for this to make the load spread across 4 LPARs?


2) I have CICS CPU,DB2 CPU, Average CPU for CICS transaction? But how to convert them into MIPS?

3) Ho much is the cost of 1 MIPS? Is this possible for us to utilize the 100% resources (MIPS) provided to us? Mostly, we have to pay without using full MIPS provided to us.

4) From you experience, Can you please tell "Golden rules in coding" to enhance the performance, decrease performance issues related to Z/OS?

5) Mostly, the MIPS increase is due to more interaction with DB2, How to make a trade-off between the DB2 interactions and the work loads?

Thanks in advance for your support !!!

You posted in the PL/1 section so where is your PL/1 question?

You need to start over with your thought about usage . . . MIPS cannot be used, MIPS is a rating not a measurement. What can be measured is how much cpu and i/o a given process uses - nothing to do with MIPS.

Your CICS system support and performance measurement people should be involved.

The particular LPAR is "hammered" because much is being done there and not so much on the other LPARS.

People in your organization are the ones who can most help with this.
Have a good one
