IWM4MDRG – Deregister a Resource From Monitoring

The purpose of the IWM4MDRG service is to deregister a resource from monitoring which was previously registered via IWM4MREG. The service allows the caller to identify a resource which is no longer involved in delays to work requests. Thus, the system may no longer alter the size of the resource to balance associated delays.

The system implicitly deregisters a resource due to repetitive errors in calling exits associated with the resource. In this case, the invocation to deregister finds that the associated resource token is invalid and returns with a warning return code. The same return code will be returned in all cases where the resource token is invalid.
