Explanation: MENTITY(modeldsn) is an optional parameter specifying the predefined model entity. It is used to define discrete profiles to RACF® for data sets to be recovered. For modeldsn, substitute the data set name of the predefined model entity. Only those data sets previously protected by discrete profiles and defined to RACF before aggregate backup are protected by discrete profiles using the model entity. If the MENTITY parameter is specified in the ARECOVER command but the model entity is not predefined, aggregate recovery fails.
If MENTITY is not specified and a discrete profile is not predefined, the data set is recovered with a default discrete profile. The profile owner is set to the high level qualifier of the data set, and UACC is set to NONE. If a RACF profile has been predefined for the data sets, they are recovered with this predefined profile.
For more information on RACF discrete profiles and model entities, see z/OS Security Server RACF Security Administrator's Guide.
Defaults: None.
