Classifying z/OS workload for WS-Notification
WS-Notification work requests for the z/OS® Workload Manager are assigned a default transaction class (TCLASS) value of SIBUS. The z/OS Workload Manager uses the TCLASS value to classify inbound work requests and to assign a service class or a report service class to each request.
