MASTFAC (z/OS and z/VSE) Keyword—Override Default Facility

Valid on z/OS and z/VSE.

Use the MASTFAC keyword to override the default facility, controlled by a batch or started task ACID, associated with a multi‑user facility such as IMS or CICS. (By default, CICS uses the CICSPROD facility, and IMS uses the IMSPROD facility. MASTFAC allows use of other defined facilities such as CICSTEST and IMSTEST.)

The following describes when the MASTFAC attribute is valid.

• MASTFAC is only of value to the BATCH or STC ACID which controls the region, not to the ACIDs that sign on.
• MASTFAC is valid only for online multi‑user regions such as CICS, IMS, CA‑Roscoe, and CA‑IDMS.

The facility name used as an operand for MASTFAC must be defined to CA Top Secret in the systems Facilities Matrix.

Additional facilities can be defined via the NAME sub-option of the FACILITY control option. For information, see the Implementation: CICS, Implementation: IMS, or Implementation: Other Interfaces Guide.

This keyword has the following format:

TSS ADDTO(region acid) MASTFAC(facility)

This keyword is used with:

• The commands CREATE, REPLACE, ADDTO, and REMOVE
• The User ACID type
• MISC9(MASTFAC) authority

Examples: MASTFAC keyword

This example assumes that the administrator had already CREATED the batch or started task ACID (CICST1) andindicates that facility CICSTEST is controlled by ACID CICST1:

TSS ADDTO(CICST1) MASTFAC(CICSTEST)

This example removes the relationship between a region and a facility:

TSS REMOVE(CICST1) MASTFAC(CICSTEST)
