APAR status

  • Closed as program error.

Error description

  • When more than one coregroups are configured in one cell and
    coregroup bridges will be configured between all these
    coregroups, HMGR0232E exceptions may happen at runtime.
    
    Sample exception:
    
    [2/5/18 13:04:09:008 CET] 0000006f GlobalBBoardB E   HMGR0232E:
    The active coordinator received a message from
    TEST_WAS90_CELL\TEST\nodeagent indicating this process is a core
    group bridge; however, there are no core group bridges currently
    configured.

    * PROBLEM DESCRIPTION: WebSphere coregroups at version 9.0     *
    *                      bridged to coregroups at versions       *
    *                      prior to 9.0 may not function properly  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    A change went into WebSphere version 9.0 to change the default
    wire format and HA protocol versions to the highest available
    values. This should only have affected the configurable
    protocol values for the main corestack, but also changed the
    non-configurable protocol values for the internal Access Point
    Group corestack. As a result, when a coregroup at version 9.0
    is bridged to a coregroup at a version prior to 9.0, the
    Access Point Group will contain a mix of v9.0 and non-v9.0
    servers and may result in a protocol version mismatch.
    

Problem conclusion

  • Code was changed to return the protocol versions for the
    Access Point group corestack to the lowest protocol values for
    compatibility when bridging coregroups at version 9.0 to
    coregroups at versions prior to 9.0.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 9.0.0.8.  Please refer to the Recommended Updates
