Use the startup procedure keyword CDSSHR with the RLS parameter to invoke RLS serialization. Whenever the control data sets are accessed in RLS mode, any values specified for CDSQ and CDSR are ignored. You can specify the CDSSHR keyword in the following manner:

    CDSSHR = {YES | RLS | NO}

where

YES

Performs multiprocessor serialization of the type requested by the CDSQ and CDSR keywords

RLS

Performs multiple processor serialization using RLS

NO

Does not perform multiple processor serialization
