Are you setting up a brand new system? If not then you should use the existing observed system data - SMF 78 from RMF - as systems vary widely. If not then the answer is probably to establish the best values when you DO have such a system.
Rules Of Thumb are inadequate in this case - as getting it wrong can seriously affect stability.

Mukhopadhyay" <[email protected]> To: [email protected] Date: 03/09/2014 04:32 Subject: z/OS IEASYSxx memory parameter values Sent by: IBM Mainframe Discussion List <[email protected]> Hello, Is there a general guideline (or a thumb rule) that can help system programmers decide the memory related parameters (like SQA, CSA etc) in IEASYSxx parmlib member? For example if 5GB of memory is allocated for an LPAR, what values (or range of values) can be generally assigned to these parameters? And does the type of predominant workload (batch/online) on that LPAR influence these values?
