If you have the ADSP attribute, RACF® automatically defines a discrete profile whenever you create a permanent DASD or tape data set that is not already protected. For a tape data set, TAPEDSN and TAPEVOL must be active. If you have the ADSP attribute, you can create and protect data sets:

• Whose names begin with your user ID.
• Whose high-level qualifier belongs to a RACF group in which you have CREATE or higher authority. Besides CREATE in the group, you also need UPDATE access to the data set when you use DFSMSdss to copy or restore a data set.
