Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V8.5 Performance Monitoring          *

    ****************************************************************
    * PROBLEM DESCRIPTION: PMI shows negative values when pretest  *
    *                      connection fails                        *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    If the pretest connection fails, a test connection timer
    starts, which creates a new connection. If the connection
    creation is successful it returns that connection to the free
    pool. When the connection is returned to the free pool without
    being allocated also, the free pool size is incremented  which
    results in the free pool size being greater than the pool size,
    which in turn causes negative PMI values.
    

Problem conclusion

  • When the connection is created in test connection timer, the
    free pool size is not incremented when the connection is
    returned to the free pool.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.6.  Please refer to the Recommended Updates
