The profile data set has these requirements:
- Organization can be either sequential or partitioned
- Record format must be fixed or fixed-block (RECFM=FB).
- It must be cataloged. Catalog the profile data set in the MASTERCAT
to avoid a deadlock between SMS and CATALOG during IPL with contention
in the SMS ASID, or a SYSZTIOT might occur.
When modifying the profile, use a disposition of OLD (DISP=OLD).
The data in the profile might be corrupted if you use a disposition
SHR.
