I suspect you should change nothing. . .
When system parameters are to be changed, it is not usually because someone decides to change because of some process they want to give more resources to.
Understood. I was thinking of a temporary change maybe to facilitate the running of this program.

If you -- or anyone else -- is going to be changing them, that person needs to do the research in reading the initialization and Tuning Reference manual to determine which, if any values, need to change. If you're attempting to run a software product from a vendor, the documentation should tell you what the various parameter values need to be. Otherwise, just changing values without understanding what's being changed AND WHY may cause various negative consequences, up to and including an LPAR completely unusable and requiring an IPL.
I did not say to change any particular value; someone needs to determine if any value needs changing. The point I was making earlier is that with OMVS, REGION=0M in a batch job may mean very little to what memory requirements are for the OMVS processes.

Is there some particular reason SAP is being run in "unix"?
I don't do SAP, but it has been my understanding that it typically runs in z/OS
I will most certainly do the research before making any changes. I'll post more information here when I find out what exactly that program does. All I know about the program is that the person who's running it (the DBA guy) does this once a year. He doesn't remember how it worked/he made it work last time.
EDIT: A quick Google says SAPCAR is used to compress/decompress CAR and SAR files. The statement I mentioned does a decompress.http://www.easymarketplace.de/SAPCAR.php#OnlineHelp
