Problem summary

  • ****************************************************************
    USERS AFFECTED:

    of a large number of clusters.
    
    Platforms affected:
    Linux (Power),Linux (x86),Linux (x86-64),Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    The cluster plug-in performs a significant amount of extraneous
    processing, including creation of a large number of threads
    when a navigator view refresh occurred. This was particularly
    evident when queue managers were members of a large number of
    clusters.
    

Problem conclusion

  • The extraneous navigator view refresh code is removed from the
    cluster plug-in.
