SUBSYS parameter

Parameter type

Keyword, optional

Purpose

Use the SUBSYS parameter to request a subsystem to process this data set and, optionally, to specify parameters defined by the subsystem.

Do not use the SUBSYS parameter for an SMS-managed data set (one with an assigned storage class).

In a loosely-coupled multiprocessing environment, the requested subsystem must be defined on all processors that could interpret this DD statement. If sub-parameters are supplied, or if the job is to execute on the system, the subsystem must be ACTIVE.

Considerations for an APPC Scheduling Environment

In an APPC scheduling environment, avoid coding the system symbolic SYSUID on the SUBSYS parameter. Symbolic substitution is inconsistent when you code SYSUID as a subparameter of SUBSYS parameter.
