Error description

  • WASPostUpgrade hangs due to large number of files collected
    by WASPreUpgrade.
    The wstemp directory can get very large. During WASPreUpgrade
    files are copied from wstemp to the migration backup directory.
    However, WASPostUpgrade keeps alot of the data it works with in
    memory - because it does most of the merging work, and therefore
    it may need to rollback the changes when a problem occurs. With
    large migration backups, this can cause memory problems and
    hangs in its processing.
    
    WASPreUpgrade should be smarter about what it is collecting from
    the wstemp directory.  If it collects only what needs to be
    processed by the isclite component, then the wstemp directory in
    the WebSphere Application Server migration backup directory
    will be smaller in size. Because there are less files
    collected WASPostUpgrade wiil not hang.

    * PROBLEM DESCRIPTION: WASPostUpgrade hangs due to an          *
    *                      unexpectedly large amount of file       *
    *                      being processed.                        *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    WASPreUpgrade collects all of the files in the wstemp
    directory within a profile.  Then when WASPostUpgrade is run,
    it hangs due to trying to process the entire wstemp directory.
    

Problem conclusion

  • When running WASPreUpgrade, we filter out all of the
    unnecessary files and directories in the wstemp directory.  The
    only file that will be processed in the wstemp directory is
    any prefs.xml file in the hierarchy.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.5.0.1, 8.0.0.5, 7.0.0.27.  Please refer to the
