Error description

  • If he same application is installed on multiple servers, but
    the servlet mappings for a WAR file in different instances
    of the application are equivalent but ordered differently,
    only one set of application instances with identically
    ordered servlet mappings will be used for routing.
    Also, if the same application is installed on servers at
    levels 8.5.5.9 or greater and on servers at level 8.5.5.8 or
    less, only one set of application instances will be used.

    If the same application is installed on multiple servers, but
    the servlet mappings for a WAR file in different instances of
    the application are equivalent but ordered differently, only one
    set of application instances with identically ordered servlet
    mappings will be used for routing.
    

Problem conclusion

  • The calculation used to determinel locations to route to was
    modified to accurately reflect identical applications. This fix
    requires that all collective controllers in the collective are
    at fix pack 8.5.5.9 or later.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 8.5.5.9.  Please refer to the Recommended Updates page for
