IWMPQRY – Querying Active Service Policy

The query active service policy routine is given control from the IWMPQRY macro. The query active service policy macro will complete the parameter list with callerprovided data and generate a stacking, space switching, program call to the query service.

The purpose of this routine is to return a representation of the active policy which could be used to explain how the system/sysplex is being managed and could be used in conjunction with current measurements to evaluate the condition of the system/sysplex. The information returned is not serialized upon return to the caller, and so may be out-of-date due to a change in policy.

The Query Active Service Policy macro is provided in list, execute, and standard form. The list form accepts no variable parameters and is used only to reserve space for the query parameter list. The standard form is provided for use with routines which do not require reentrant code. The execute form is provided for use with the list format for reentrant routines.

The parameter list must be in the caller's primary address space or be addressable by the dispatchable unit access list.
