MQXCLWLN - Navigate Cluster workload records

The MQXCLWLN call is used to navigate through the chains of MQWDR, MQWQR, and MQWCR records stored in the cluster cache.

The cluster cache is an area of main storage used to store information relating to the cluster.

If the cluster cache is static, it has a fixed size. If you set it to dynamic, the cluster cache can expand as required.

Set the type of cluster cache to STATIC or DYNAMIC using either a system parameter or macro.

  • Use the system parameter ClusterCacheType on Multiplatforms.
  • Use the CLCACHE parameter in the CSQ6SYSP macro on z/OS .
