Error description
Using a Sysplex Optimized workload, a CMAS may remain frozen in the workload if it is restarted.

Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex SM V4R1M0 Users * **************************************************************** * PROBLEM DESCRIPTION: - When a workload becomes frozen * * because a CMAS terminates while CPSM * * WLM routing and target regions * * connected to it are active, if at * * least one target region is still * * active when the CMAS is restarted, * * the workload may not be unfrozen. * * * * - When WLMAWTOR records are requested * * through the API or WUI, the OWSTATE * * attribute may display as INACTIVE * * for a routing region even though * * Sysplex optimization is active for * * the region, if the region is * * connected to a CMAS other than the * * CMAS to which the API program or WUI * * server connected. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, all CMASes and MASes must be * * restarted. Note that the restarts do not * * need to occur at the same time. * **************************************************************** - When a CMAS termination causes a workload to become frozen, all target regions connected to the CMAS at the time of its termination have a flag turned on in their EYURWAOR control block to indicate that they were lost due to their CMAS being terminated. When the CMAS is restarted, and the still active target regions re-connect to the CMAS, the flag is used to unfreeze the workload. A logic error in module EYU0WMWD (WMWD) causes the flag to be reset before it can be used to unfreeze the workload, resulting in the workload remaining frozen. - A CMAS considers a routing region to be either local (connected to the CMAS) or remote (connected to another CMAS). For local routing regions, method EYU0WMTJ (WMTJ) is called to perform Workload Join of the routing region after the region is Topology Connected to the CMAS. For remote routing regions, WMTJ is called either when the CMAS imports the workload, or if the region is not active at that time, when the region is Topology Joined to the CMAS. If a CMAS is importing the workload at the same time it is performing Topology Join for one of the routing regions associated with the workload, it is possible that WMTJ may be called for workload import before Toplogy Join completes for the region. When that occurs, the region's CICS version will not be set in the CICS system descriptor block (CSDB) for the region. As a result, WMTJ will treat the region as a pre-CICS V6R6M0 region, and will not set the OWSTATE attribute to ACTIVE.
Problem conclusion
- WMWD has been updated to not clear the EYURWAOR lost contact flag before it can be interrogated when a CMAS connects to a target region. - WMTJ has been updated to not perform Workload Join for a remote routing system until after Topology Join has occurred. This will ensure that the region's CICS version will be set in the CSDB before WMTJ runs.
