SHCDSvvvThe data set nameThe job with which the unit of recovery was associatedThe step within the job with which the unit of recovery was associatedv Whether the unit of recovery will be committed or backed out if it is retriedShunting is caused by errors such as the following:v C-FAILED: A commit failed.vvvvvvvB-FAILED: A backout failed.IO-ERROR: An I/O error occurred on the data set.DS-FULL: The data set was full; no space on DASD to add records.IX-FULL: A larger alternate index is required.LOCK: A failure occurred during an attempt to obtain a lock during backout.LOG: A log stream became or was made unavailable.CACHE: A cache structure or connection to it failed.This parameter requires that you have UPDATE authority to the data setspecified.Abbreviation: LSHLISTSUBSYS(subsystem|ALL)Lists information about a specific subsystem or all subsystems known to theSMSVSAM server:vSubsystem status– Active for batch– Active or failed for onlinev A summary showing whether the subsystem’s shared data sets have:– Lost locks– Retained locks– Non-RLS update permittedFor an active subsystem, LISTSUBSYS gives the number of held locks, waitinglock requests, and retained locks. For a failed subsystem, LISTSUBSYS showsthe number of retained locks.Abbreviation: LSSLISTSUBSYSDS(subsystem|ALL)Lists information about a specific subsystem or all subsystems known to theSMSVSAM server, including data sets that it is sharing. For each subsystem,this parameter lists the following information:vvvSharing protocol (online or batch)The status (active or failed)Recovery information for each shared data set:– Whether it has retained locks owned by this subsystem– Whether it has lost locks owned by this subsystem– Whether there are locks not bound to the data set– If forward recovery is required– If non-RLS update is permitted– The permit-first-time switch settingAbbreviation: LSSDSL342 z/OS V1R6.0 DFSMS Access Method Services for Catalogs
SHCDSLISTRECOVERY(base-cluster)lists data sets requiring recovery and the subsystems that share those data sets.Recovery indicators listed are:v Lost locksv Retained locksv Non-RLS update permittedv Forward recovery requiredAbbreviation: LRCVYLISTALLLists all information related to recovery for subsystems and VSAM spheresaccessed in RLS mode. The output from this parameter can be quite large.Abbreviation: LALLFRSETRR(base-cluster)This parameter sets the forward-recovery-required indicator. Until reset withthe FRRESETRR parameter, access is prevented until forward recovery iscomplete.If you use a forward recovery utility such as CICSVR that supports RLS,DFSMStvs, or both, do not use this parameter.Abbreviation: SETRRFRUNBIND(base-cluster)This parameter unbinds the retained locks prior to restoring or moving thedata set. These locks protect uncommitted changes and are needed for eventualbackout. They must be rebound by using the FRBIND parameter.If you use a forward recovery utility such as CICSVR that supports RLS,DFSMStvs, or both, do not use this parameter.Abbreviation: UNBFRBIND(base-cluster)Use this parameter after BLDINDEX to rebind the associated locks to therestored data set.Attention: Between the unbind and the bind, do not delete any clusters in thesphere or change their names.If you use a forward recovery utility such as CICSVR that supports RLS,DFSMStvs, or both, do not use this parameter.Abbreviation: BINDFRRESETRR(base-cluster)Use this parameter after forward recovery is complete and after locks havebeen bound to the new location of the data set using FRBIND. This allowsaccess to the newly recovered data set by applications other than the forwardrecovery application.If you use a forward recovery utility such as CICSVR that supports RLS,DFSMStvs, or both, do not use this parameter.Abbreviation: RESETFRDELETEUNBOUNDLOCKS(base-cluster)The FRDELETEUNBOUNDLOCKS parameter lets you delete locks in the rarecase when a successful forward recovery is not possible.
