Subject: Need to understand TCB CPU and SRB CPU
Posted: Mon Mar 20, 2017 9:32 pm (GMT 5.5)
Hi, I have merged 2 cobol pgms to read the input only once. I have tested the new program with 10 million records. In the spool I found the details - CPU: 0 HR 10 MIN 38.06 SEC SRB: 0 HR 00 MIN 05.97 SEC for old pgms and CPU: 0 HR 10 MIN 50.81 SEC SRB: 0 HR 00 MIN 02.34 SEC for new pgm. The CPU got increased little bit and there is 50% reduction in the SRB time. Can you help me to understand how SRB time affects overall run time of the job and Can I consider SRB time reduction as valid savings?
