Error description

• After implementing Sysplex Omtimized Workload management within
  some workloads for certain target AOR regions, any WUI workload
  views (ie. WLMAWAOR, WLMATARG, etc) received message:
  .
    EYUVC1278E unable to obtain data for requested View. 'GET'
    (GET) request failed (Failed, Exception).
  .
  None of the routing regions have been set optimized yet.
  The APIGET failure was the result of an RSSR failure occurring
  in WABA / WABB on a RSSR_INQUIRE_TARGET_STATUS function with a
  response of 02 RSSR_EXCEPTION and a reason of 0A
  RSSR_TARGET_NOT_KNOWN.   The region that received the RSSR
  failure was located on a different plex then the region where
  the request was executed.
  .
  The trace may show either of the following exception:
    WABA XLSD XLST WLM EXCP.     14 DFHRSSR EUI  G333297  CMAS
  .
  where the WABA entry trace point id 14 indicates DFHRSSR failed
  and around x'580' in the STAK, the RSSR structure shows the MAS
  having the problem at +2C.
  .
  Or...
    WABB XLSD XLST WLM Lv-13 13003 RSSRRESP Ext  B326599  CMAS
  .
  where the RSSR parm list (RSSRplst) shows the MAS having the
  problem at +34.

  *                 do not need to be brought down and restarted *

  ****************************************************************
     When Sysplex Optimized Workload is active for target regions,
  status is maintained by the RS Domain in a Coupling Facility
  Data Table.  Because a coupling facility can only be accessed by
  one sysplex, region status information will only be available to
  regions executing in the same sysplex as the target region.
     When a target region is activated in a CMAS which manages an
  active workload, the optimization state is set from attributes
  of the CICS System Definition (CSYSDEF) resource for the region,
  without considering whether Region Status is available in the
  local coupling facility.
     Modules EYU0WABA (WABA - Browse Active AORs) and EYU0WABB
  (WABB - Browse Active Target Regions) call the RS Domain to
  retrieve Region Status information.  If the target region is
  in a different SYSPLEX, the RS Domain will return a response of
  02 (RSSR_EXCEPTION), and a reason of 0A (RSSR_TARGET_NOT_KNOWN).
  WABA and WABB interpret this as a failure, and erroneously re-
  turn a response of EXCEPTION and a reason of METHOD_FAILED.
  

Problem conclusion

• Modules EYU0WABA and EYU0WABB were modified to detect reason
  0A (RSSR_TARGET_NOT_KNOWN) and set the reported Optimization
  Status for the target region to INACTIVE.  Several modules which
  initialize or update the WLM AOR Descriptor (WAOR) in a CMAS
  were modified to compare the local SYSPLEX with the SYSPLEX in
  which the target regions executes, and to set the local optimi-
  zation state to INACTIVE if they are different.  This prevents
  TORs which connect to the CMAS from attempting to use region
  status information which is not available in the local SYSPLEX,
  in making routing decisions.
