APAR status

  • Closed as new function.

Error description

  • Datasource Connection Pool minimumPoolSize has to be 0 by
    default for newly created datasources to help in draining off
    all the connections when the connection pool is not used for
    prolonged periods as part of maintanence activity. This can
    help avoid connections becoming stale.

    * USERS AFFECTED:  All users of IBM WebSphere Application      *

    * PROBLEM DESCRIPTION: Datasource Connection Pool              *
    *                      minimumPoolSize to be 0 by default      *

    * RECOMMENDATION:                                              *
    ****************************************************************
    The default value of  Minimum connections in the datasource
    Connection Pool has been changed to 0 (previously 1),
    which helps to drain off the connections when the server is
    idle or on maintanence for prolonged time periods and thus
    can prevent connections from becoming stale.
    This change applies only to newly created datasources. For all
    existing datasources their current value for the minimum
    connections will continue to remain the same.
    

Problem conclusion

  • The WebSphere J2C component has been updated to use the
    default value of 0 for minimum connections settings for newly
    created datasources.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.9.  Please refer to the Recommended Updates
