Amit. Firstly you should have RMF monitor III setup so that it can see the address spaces in all the LPARs in the Sysplex. Make sure RMF address spaces are at high priority. You can then see who is getting the CPU and how much the LPAR is using. Have the TSO userids of selected (trusted not to abuse the priority) performance people set to a single period high priority service class. Alternatively you can get someone reset to a high priority at problem times.
It is useful to have some TSO users stay logged on nearly all the time. Not sure of the best options to achieve this.

My questions might sound foolish or/and inappropriate, but can assure, are not just for Fun. eager to learn, if possible some help/experience shared.
