The access authority you need to the input and output dump data sets depends on many factors not under DFSMSdss control because access-authorization checking is performed by Open/Close/End-of-Volume (O/C/EOV) processing. The primary considerations are as follows:

• You need READ access if the input dump data set is protected.
• You need either UPDATE or ALTER access if the output dump data set is protected.
• You may need UPDATE access to the catalog if the output data set is going to be cataloged.
