Restricting multiple access

The user can restrict the use of multiple access by means of the following commands:

/ADD-FILE-LINK ...,SUPPORT=*DISK(SHARED-UPDATE=*NO)

PLAM libraries are opened by default with SHARED-UPDATE=*YES. An ADD-FILE-LINK command with SHARED-UPDATE=*NO and the opening of this library with the specified link name prevents further update accesses.

/SECURE-RESOURCE-ALLOCATION FILE=

The library is reserved exclusively for this task.

/MODIFY-FILE-ATTRIBUTES ...,PROTECTION=

Only users who have the necessary access rights can access the library.

For a description of these commands, see [4 (Related publications)].
