DB2FAC—Group and Protect DB2 Subsystems

Valid on z/OS.

Use the DB2FAC control option to:

• Logically group DB2 subsystems under different facility names
• Control whether the resources in a DB2 subsystem is protected

All entry methods are supported.

This control option has the following format:

DB2FAC(ssid=facility)

ssid

Identifies the name of the DB2 subsystem

facility

Indicates the facility name to which the DB2 subsystem is associated.

Examples: DB2FAC control option

This example indicates that DB2 subsystems DB2A and DB2B are grouped under DB2PROD, while DB2 subsystems DB2C and DB2D are under DB2TEST:

DB2FAC(DB2A=DB2PROD)
DB2FAC(DB2B=DB2PROD)
DB2FAC(DB2C=DB2TEST)
DB2FAC(DB2D=DB2TEST)

Protect DB2 Subsystem Resources

The mode on the facility defined for the DB2 subsystem controls the protection of the DB2 subsystem resources. Specifying a non‑DORMANT mode for the facility associated with the DB2 subsystem protects its resources. A mode of DORMANT, or no DB2FAC control option specification for a DB2 subsystem, indicates that neither CA Top Secret for DB2 nor native DB2 will protect the resources in the DB2 subsystem. For information, see the Implementation:DB2 Guide

This example allows the protection of DB2 resources:

DB2FAC(DB2A=DB2PROD)
DB2FAC(DB2B=DB2PROD)

A specified mode of the following will allow protection of DB2 resources:

FACILITY(DB2PROD=MODE=FAIL)

The mode for the checks as well as other facility options are determined by the settings of the DB2PROD facility (LOG, ABEND/NOABEND). For example, if the user is logged onto TSO the MODE as well as all other facility control options are determined by the DB2PROD facility but only for DB2 resource checks. All other normal functions of TSO continue to occur under the TSO facility.
