RAMAX SIZING CICS PERFORMANCE OPTIMIZATION

Postby xboss » Tue Jun 26, 2012 9:07 pm

I am trying to optimize CICS performance based on RAMAX size value. The resulting number under my consideration are CPU wait time, Virtual storage usage, Number of request processed by CICS within certain time interval. A Strobe is run against online CICS regions. I am trying to look at a performance of program/module that is responsible for communications. I see DFHZ* module perform specific VTAM function while doing communication. But there are a lot of DFHZ* module running.

DFHZCA VTAM WORKING SET MODULE
DFHZCB DFHZHPSR AUTH PATH SRB REQOR
DFHZCC VTAM WORKING SET MODULE
DFHZCP TERMINAL MANAGEMENT PGM
DFHZCX LOCATE ISC/IRC REQUEST

My question is, Is there any specific DFHZ* module I should be looking at? Thank you in advance for sharing your knowledge.
