Quiescing or enabling a secondary lock structure

To quiesce (stop) or enable a VSAM RLS secondary lock structure, enter the VARY SMS command, as follows:

 V SMS,CFLS(lockstructurename),Quiesce|Enable

When a VSAM RLS secondary lock structure is enabled, SMSVSAM attempts to connect to the structure during open processing for a VSAM data set using a storage class containing a lock set that references that lock structure. Once the data set is open, the lock structure holds record locks for the sphere.

The quiesce option stops access to the VSAM RLS secondary lock structure. SMSVSAM does not allow any new spheres to access this lock structure. All spheres that are already connected are allowed access until they close. When all of the connected spheres close, the lock structure transitions from Quiescing to Quiesced and SMSVSAM disconnects from the lock structure.

Note: The VARY SMS command is not valid for the primary CF lock structure IGWLOCK00.
