MXG Dataset TYPE75 contains these slot statistics for each paging dataset for each RMF interval:
AVGUSED ='AVERAGE*SLOTS*USED' MAXUSED ='MAXIMUM*SLOTS*USED' MINUSED ='MINIMUM*SLOTS*USED' SLOTS ='NUMBER*OF SLOTS*DEFINED' UNUSLOTS='UNUSABLE*SLOTS' Barry Merrill Herbert W.

I was wondering if there are any guidelines on what can be used today. This should be kept to z/OS V1.12, 1.13 and 2.1 which I think will be the more dominant operating systems in use right now. I know that the number of Slots will drive what I allocate. So I am looking for the following information. I have not done this in many years so I am very rusty. 1) How to calculate the number of slots per page datasets a) I need to base this on 3390 Mod 3/9/27/54 2) What do I need to stay away from when determining where the page datasets go a) For example, if I use a Mod27 and I need to place multiple page datasets on the volume Should they all be for the same LPAR if in a PLEX Should they all be for unique LPARs if in a Plex 3) What are the maximum values I can create a page dataset? Can I use a whole Mod3/9/27/54 for ONE page dataset? I have looked through Hot Flashes (Cheryl Watson) and MXG sourclib. I have run through some of the Redbooks and share presentations. I am now looking for real life thoughts. I also thought this would be a good topic for the archives.
