Using the Queueing Manager Connect Exit

A queueing manager can optionally provide the name of an exit routine on the QMGR_EXIT@ parameter of IWM4CON when it connects to workload management. Through this exit, the queueing manager is informed when workload management has had to delete queued work requests associated with the queueing manager. Workload management deletes all queued requests when:

• The installation deletes the application environment (that is, activates a service policy that does not contain the application environment).
• The queueing manager address space disconnects.

When the exit routine is invoked, register 1 contains the address of a parameter list mapped by the list form of the IWMQCXIT macro. The parameter list includes an indicator of what action workload management has taken and the input values specified previously by the queueing manager when it queued the work request using IWM4QIN.

The execute and standard form of IWMQCXIT are intended for use only by the operating system.
