See DMCL1DY.Action for rolled-off GDS has been specified forthis Management Class. See DMCRLOMG.The number of generation data group elementsthat can occupy primary storage in for thisManagement Class has been specified. SeeDMCPELEM.DMCFBKFQ The backup frequency for data sets associated withthis Management Class has been specified. SeeDMCBKFQ.The partial release criteria for non-VSAM data sets in thisManagement Class. The bit combinations in this field showwhether or not data sets in this Management Class can haveunused space automatically released and the release conditions.This field is mapped by constants DMCRLFYE, DMCRLFCN,DMCRLFNO, DMCRLFYI, and DMCRLFCI. The following areindicated if the specified bit is ’1’.DMCPREL Unused space is released unconditionally.DMCPRCN Unused space is released only if the data set has asecondary allocation.DMCPRIM This bit indicates that the release is to be doneeither during the Space Management cycle or whenthe data set is closed, whichever comes first.Generation Data Group (GDG) Attribute Flags.DMCRLOMG This flag denotes the action to be done on aGeneration Data Set (GDS) when it is rolled-off.1 The GDS is to be migrated afterbeing removed from the GDG.0 The GDS is to expire after beingremoved from the GDG.This field shows how many of the newest generations of aGeneration Data Group (GDG) can occupy primary storage. Anygenerations older than this set of newest generations are eligible tomigrate. Possible values range from 0 to 255.Data set expiration criteria flags. The following is indicated if thespecified bit is ’1’.DMCARNOLThis flag indicates that the number of days to keepthe backup is unlimited.This field indicates the action taken when a data set expires in thisManagement Class. It is mapped by DMCEANUL, DMCEADELand DMCEARC.0 Expiration action is null.1 Expiration action is delete.2 Expiration action is backup.This field specifies the number of days to retain the backup copyof a data set managed by this Management Class.Data set retention flags.Appendix F.
