Automatic TVTOC tape volume profiles z/OS Security Server RACF Security Administrator's Guide SA23-2289-00 |

RACF® creates an automatic
TVTOC tape volume profile when one of the following
occurs:
When RACF creates an automatic
tape volume profile, RACF does
not use modeling, except possibly for the owner field as specified
below. The tape volume profile that RACF creates
contains the following fields:
You can change any of these fields by using the RALTER or PERMIT command. (The most likely change is adding other users to the access list so that they can define data sets on the tape volume.) When the security retention periods for all data sets on a volume that is protected by an automatic tape volume profile have expired and a user uses the volume for output, RACF deletes the volume's profile. When a user creates a new data set on such a tape volume and specifies PROTECT=YES on the JCL DD statement or has the ADSP attribute, RACF creates a new discrete tape volume profile with a TVTOC and generates a discrete profile for the data set. If the user does not specify PROTECT=YES on the JCL DD statement or have the ADSP attribute, RACF does not create new profiles for the volume or the data set. Therefore, the volume and any data sets on it are no longer RACF-protected and any user can read or write data on the volume. |
