CATVMFX EXTEND Requirements

Before performing the dynamic extend, ensure that the following conditions are met:

• The new VMF is initialized with CATVMFI.
• The new VMF and the alias belong to the same user catalog, for example, their high level qualifiers must match.
• The last VMF backup was no longer than three hours before the dynamic extend.
• The new VMF is large enough to contain all active records in the old VMF.
• The new VMF has enough AUX records to contain those records that are used in the old VMF.
• The new VMF contains the VSNs of all the active volumes in the old VMF.
• The new VMF is cataloged to the same user catalog as the old VMF.
• XUPD user exits, that open the VMF for record processing, must process CLOSE calls from TLMSUPDT. CATVMFX requires a successful deallocation of the old VMF to complete. See the sample in HLO.CTAPSAMP(TLMSXUPD). If you use a custom TLMSXUPD exit, contact CA Support to review your exit.
