DFSMS CACHE
CONNECT PROTOCOL HAS DETECTED THAT RLS_MAXCFFEATURELEVEL IS NOW SET
TO 'Z'. GREATER THAN 4K CACHING IS NOT ACTIVE FOR ANY NEW VSAM SPHERES
THAT ARE OPENED USING VSAM RLS PROTOCOLS. EXISTING VSAM OPENS USING
VSAM RLS PROTOCOLS WILL NOT CACHE DATA GREATER THAN 4K.
Explanation
A change to the SMS PARMLIB keyword Rls_MaxCfFeatureLevel
was completed by the SET SMS or SETSMS command. All VSAM spheres using
RLS protocols will not cache data that is greater than 4K into the
coupling facility.
- Feature Protocol Level
- Meaning
- Feature Level = Z
- Original state of DFSMS cache
connection code. No feature-level processing is performed.
- Feature Level = A
- Feature-level processing is performed. If all systems in the sysplex
are at this level, RLSCFCACHE values are honored.
System action
