APAR status

  • Closed as program error.

Error description

  • Shared DB connections in the  background threads will cause
    connection "leak" (increase and stick to
    number of threads). One possible fix would be disable the
    shared DB  connection by default in the concurrent1.0
    package,
    or at least make it  an easy configuration option,

    ****************************************************************
    WebSphere Application Server Liberty does not have the
    capability to override the default connection sharing behavior
    when using direct lookups.
    

Problem conclusion

  • This APAR adds the property enableSharingForDirectLookups on the
    ConnectionManager to allow the connection sharing to be
    controlled. If set to true, which is the default, connections
    are shared. If set to false, connections are unshared.  This
    property will only affect resources accessed through direct
    lookup.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.1.  Please refer to the Recommended Updates page for
    delivery information:
    http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
    

Temporary fix

  • The connection sharing can be controlled by using indirect
    lookup, either using a resource reference or resource
    injection.
