Error description

  • Error Description￘
    The Local Comm code does not honor the connection timeout
    value.  This can cause a thread that does a local connect call
    to hang.
    
    LE trace back of a thread hung in this state looks like:
    
    bboclscc(bacb*,CF_SessionHandle*,void*,void*,MVS::STOKEN*,int&,i
       nt*,int*,int*,int*)
    CF_Local_Connection::init_As_Client(CF_ConnectionData*)
    CF_TCP_Request::connect(int,CF_ConnectionData*)
    Java_com_ibm_ws_tcp_channel_impl_ZAioTCPChannelCPPUtilities_loca
       lConnect
    RUNJAVATHREAD
    javaProtectedThreadProc
    j9sig_protect
    javaThreadProc
    thread_wrapper
    CELQPCMM
    
    Java stack shows:

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V7.0, V8.0, and V8.5                 *
    ****************************************************************
    * PROBLEM DESCRIPTION: WebSphere Application Server for z/OS   *
    *                      Control region thread hung trying to    *
    *                      connect to another server.              *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The server issued a local communication connect call (bboclscc)
    to establish a connection with another server.  A timing window
    was hit in termination of the target server that left the
    caller of the connect hung in the local comm PC routine
    (bboclspc).  There is no client-side timer to break the caller
    of the connect request out of its wait for the connection to
    complete.
    

Problem conclusion

  • Code has been added to honor the connection timeout value
    supplied to the Local Communication Channel.
    
    APAR PM61861 requires changes to documentation.

    The following changes to the z/OS version of the WebSphere
    Application Server Version 7.0 Information Center will be made
    available in September, 2012.
    
    The topic "Abend reason codes" will be updated to include the
    following description of the 0416001C abend reason code:
    
    Abend code: DC3
    Abend Reason: 0416001C
