Cluster workload exit call and data structures
This chapter provides reference information for the cluster workload exit and the data structures it uses. This is general-use programming interface information.
You can write cluster workload exits in the following programming languages:
- C
- System/390(R) assembler (WebSphere MQ for z/OS)
The call is described in:
The structure data types used by the exit are described in:
- MQWXP - Cluster workload exit parameter structure
- MQWDR - Cluster workload destination-record structure
- MQWQR - Cluster workload queue-record structure
- MQWCR - Cluster workload cluster-record structure
Constants relating to the cluster workload exit are listed with their values in Chapter 12, Constants for the cluster workload exit.
Throughout the following topics queue-manager attributes and queue attributes are shown in full, as defined in the WebSphere MQ Application Programming Reference book. The equivalent names that are used in the MQSC commands described in the WebSphere MQ Script (MQSC) Command Reference book are shown in Table 4 and Table 5.
