IWMRQRY – Collecting Address Space Delay Information

IWMRQRY is the interface reporting products should use to obtain address space related general execution delays. Enclave related information may optionally be requested.

The macro will complete the parameter list with caller specified data and invoke a stacking, space switching PC routine in the WLM address space. Address space related data collected will be aggregated on an address space basis, while enclave related data (if requested) will be aggregated by enclave.

If a user does not know the size of the answer area required by the service, he should code issue IWMRQRY with ANSLEN set to zero. The length of the answer area will be placed in QRYLEN.

The IWMRQRY 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 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 in a dataspace accessible by the current unit of work's dispatchable unit access list (DUal).
