Bypassing management and storage class access checks during COPY (PN72592)

A COPY operation might not be successful when the owner of the data set does not have read access to the STORCLAS or MGMTCLAS routines that allocate the target data set, even though the ADMINISTRATOR keyword is specified. The ADMINISTRATOR keyword gives access to the data set, not to the automatic class selection (ACS) routines that are used for STORCLAS or MGMTCLAS processing.

This function is affected by setting the flag at offset X'3D' in ADRPATCH. The settings are listed below:

X'00': DFSMSdss functions normally as described above.
Any setting other than X'00': When the ADMINISTRATOR keyword is specified, DFSMSdss causes SMS to bypass access authorization checking to the ACS routines for STORCLAS and MGMTCLAS when allocating the target data set during a COPY operation.

To set the flag to on dynamically, use the SET PATCH command. To set the flag to on permanently, modify the sample JCL (see Sample JCL) as follows:

//SYSIN DD *
   NAME ADRDSSU ADRPATCH
   VER   3D        00
   REP   3D        FF
