Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of WebSphere Virtual              *
  *                  Enterprise component of IBM WebSphere       *
  *                  Application Server                          *
  ****************************************************************
  * PROBLEM DESCRIPTION: This problem is due to an incorrect     *
  *                      check for maintenance mode.             *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  In the HTTPDebugResponse module, in the XD dwlm client,
  there's a test for maintenance mode.  If the test returns that
  all the servers have maintenance mode set, it reports that
  as reason for not routing (503).
  However, if any (or all) of the servers are in
  "inprogress:affinity" (or whatever prefixed with
  'inprogress:') then the ODR should continue to route to those
  servers, and the HTTP Debug code should not cite that as
  reason for not routing, as it may mask the true problem.
  Rather, it might NOTE that all the servers are in
  "inprogress:..." mode, but continue testing for other 503
  conditions.
  

Problem conclusion

• The code is changed to check for maintenance mode correctly now.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.4.  Please refer to the Recommended Update
