Deregistering as an Eligible Server

When a server is no longer available for processing work, the server should issue the IWMSRDRS macro to deregister. A server should issue IWMSRDRS at address space termination. This makes the system aware that the server is no longer a candidate for future work requests, and can remove it from the list of eligible servers.

For complete information about the IWMSRDRS macro, see IWMSRDRS – Deregister a Server for Sysplex Routing.
