Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V6.1.0 and V8.0.                     *
    ****************************************************************
    * PROBLEM DESCRIPTION: An outbound IIOP connection from a      *
    *                      WebSphere Application Server for z/OS   *
    *                      server gets unexepectedly closed by a   *
    *                      network firewall due to inactivity.     *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The property com.ibm.CORBA.EnableServerKeepAlive is used by
    WebSphere to control the TCP/IP keep alive setting for
    outbound IIOP connections.  The WebSphere code uses this value
    to set the SO_KEEPALIVE socket option, however the code
    incorrectly sets it to 0 regardless of whether the value is
    true or false.  This is due to a problem with the way
    WebSphere is setting SOL_SOCKET socket options.
    

Problem conclusion

  • WebSphere code was fixed to properly set SOL_SOCKET socket
    options, which will cause the SO_KEEPALIVE socket option to
    properly be set to 1 when com.ibm.CORBA.EnableServerKeepAlive
    is set to true.
    
    APAR PM46444 is currently targeted for inclusion in Service
    Level (Fix Pack) 6.1.0.43 of WebSphere Application Server V6.1.0
    and Fix Pack 8.0.0.2 of WebSphere Application Server V8.0.
    
    The fix will also be delivered as sysrouted APAR PM49812 in
    WebSphere Application Server V7.0 for z/OS.
