Error description

  • When we use monitor feature on Liberty, we can monitor the
    several  counters like "Used", "Free", "Created" and
    "Destroyed" of  connection pool by using Liberty admin
    center.
    If we set "agedTimeout" to "-1" for a connection pool, the
    existing free connection will be destroyed until the
    number of existing free connection is equal to minPoolSize.
    Then, the remaining connection would keep to stay in the
    free pool because of "agedTimeout=-1".
    
    Let's assume the following condition.
    * agedTimeout=-1
    * minPoolSize=5
    
    Under this condition, if only two connections are created
    and used, the "Used" and "Created" counter are increased
    to 2. And when the connections are returned to free pool,
    "Used" is still "2" although "Free" counter is increased
    to "2".
    So the "Used" value doesn't reflect the actual in-use
    connection.

    * PROBLEM DESCRIPTION: The Used Connections Monitor Graph does *

    * RECOMMENDATION:                                              *
    ****************************************************************
    The Used Connections Monitor Graph does not display the correct
    value for Used Connections.  The description on the panel was
    confusing and the value displayed for 'Used Connections' was
    incorrect.
    
    The wording on the panel was corrected for the Connections from
    'Used' to 'In Use' and the correct  value is displayed.
    

Problem conclusion

  • The 'Used Connection' text was changed to read 'In Use', and the
    hover help now properly displays how it is calculated.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.3.  Please refer to the Recommended Updates page for
