We have shared DASD between multiple LPARS in a sysplex I was wondering if anyone had experience of using RLS for catalogs, as introduced with with Z/OS 2.1? In particular, anyone using this with MIM. MIM has to be initialised before RLS can start (several references to this in APARS). We use RLS with endevor VSAM datasets, and this is not an issue, but as catalog access is so basic to the system, I am thinking we might have to initialise MIM before JES (and have it's parmlib in the master catalog), to avoid a chicken and egg situation. Just wondering if anyone else has considered this.
