ACBSHR

1 ACBSHR=
2.1! N
2.1 Y

ACBSHR

Specifies whether the application control blocks (ACBs) that this IMS™ subsystem uses are also used by other IMS™ subsystems.

N

Only this IMS™ subsystem uses the ACBs.

Y

This IMS™ subsystem and other IMS subsystems use the ACBs.

When IMS™ management of ACBs is enabled (ACBMGMT=CATALOG), the ACBs are in the IMS directory data sets of the IMS catalog. Set ACBSHR to Y when multiple IMS subsystems use the same IMS catalog.

When the ACBs are managed by your installation (ACBMGMT=ACBLIB), the ACBs are in ACBLIB data sets. Set ACBSHR to Y when multiple IMS subsystems use the same ACBLIB data sets.

This parameter is optional. If it is not specified on the FMN1POPI macro statement, FM/IMS uses either the value specified on the FMN1POPD macro statement (if specified on that statement), or N (otherwise).

The user cannot override the value you specify for this parameter.
