Usage restrictions

In contrast to the usage type, usage restrictions can also be changed at short notice. There are different restrictions for creating files, file processing and for temporarily deactivating a volume set.

Usage restrictions are defined with the MODIFY-PUBSET-RESTRICTIONS command in the operands below:

• NEW-FILE-ALLOCATION
  Restrictions for creating files.
  Only physical allocation or a general lock are possible.

  A restriction may be revoked only if access to the volume set is not restricted.

• VOLUME-SET-ACCESS
  Restrictions for processing files on TSOS.

• ALLOCATION-ON-VOLUME
  Usage restrictions for single volumes.
  Only physical allocation or a general lock are possible.
