In order for VSAM RLS processing to take place,
you must ensure
the following:
- Run all systems performing RLS as a Parallel Sysplex®
- Define and activate
at least two sharing control data sets (SHCDS),
and one spare SHCDS for recovery purposes
- Define CF cache
and lock structures to MVS, using the CF resource
manager (CFRM) policy. Define CF cache structures in the SMS base
configuration.
- Associate
CF cache set names with storage class definitions, and write ACS routines
to associate storage class definitions that map to CF cache structures
with data sets.
- Change the attributes for a data set to specify
whether the data
set is to be recoverable or nonrecoverable. Specify LOG(NONE) if the
data set is nonrecoverable; specify LOG(UNDO) or LOG(ALL) if the data
set is recoverable.
For more information about using the CFRM policy to define CF structures,
see z/OS MVS Setting Up a Sysplex.
For more information about specifying recoverable and nonrecoverable
data set attributes, see z/OS DFSMS Using Data Sets.
