That's a big upgrade. From an unsupported release of z/OS to a version of z/OS that isn't the latest anyway.
You don't say how you measure CPU usage (your 'detection' methodology). Are they standardized RMF reports? Has there been an associated hardware upgrade (i.e. any change in MSU's)?

Sent: Friday, 13 March 2015 5:26 PM To: [email protected] Subject: Migrating z/os version and increase of cpu usage We have migrated from Z / os 1.7 to Z / os 1.13. Applications that run on "mainframe" are the same. We detected a significant increase in CPU usage both transactions "Cics" and processes "batch". I understand the code of the operating system and software products has increased to provide added functionality or new facilities. My question and / or question is whether software version change involves additional cost sensitive consumer cpu?
