Error description
When trying to load a workload specification the following messages occur: . EYUWM0400I Workload Specification (WLSPC) has been successfully installed for context (PLEX) - initiated by CMAS (CMASA) EYUWM0401E Workload Specification (WLSPC) failed to install for (PLEX) - initiated by CMAS (CMASA) EYUWI0081I WLM Workload build process for context (PLEX) has been completed - initiated by CMAS (CMASA) EYUWI0082E WLM Workload query process failed for context (PLEX) - directed to CMAS (CMASB) EYUWM0401E Workload Specification (WLSPC) failed to install for context (PLEX) - initiated by join of router (region3) . The query workload request if failing because SCLA is returning a status of XCLA_DUPLICATE_KEY on the ADDCLST function. From the EYUWI0082E message, CMASA believes CMASB has the workload.

In most situations, the second instance of WMWC will wait for the first to complete, at which time it will recognize that the workload has been built, and will not attempt to build the workload also. However, in some situations, both WMWC processes can execute simultaneously, resulting in the errors documented above.
Problem conclusion
WMWC has been updated to issue a CICS ENQ upon starting. The resource name of the enqueue will be a concatenation of the CICSplex name and the workload name (WLMSPEC) that the routing region is associated with. After completing the workload build, WMWC will release the enqueue. This will ensure that the workload build process is serialized.

A CMAS may fail to install a CPSM WLM workload properly when two or more routing regions start at the same time and attempt to import the workload. The following messages may be issued by the CMAS to indicate the failure: EYUWM0401E Workload Specification (<wlmspec>) failed to install for context(<plexname>) - initiated by CMAS (<cmasname>) EYUWI0081I WLM Workload build process for context (<plexname>) has been completed - initiated by CMAS (<cmasname>) EYUWI0082E WLM Workload query process failed for context (<plexname>) - directed to CMAS (<cmasname>) EYUWM0401E Workload Specification (<wlmspec>) failed to install for context(<plexname>) - initiated by join of router (<torname>) Examination of the CMAS's auxtrace dataset may show the following exceptions: Method TPID Debug text ------ ---- ---------- WMWB 1 WMWBXCLA WMQB 14 WMQBWMWB WMQM 13 WMQMWMQB WMWC 16 WMWCWMQM WSPL 17 UnlkB4Lk When a workload does not exist under a CMAS, its creation is initiated when the first routing region for the workload starts.
