Error description

  • For DDF threads, the termination of related execution unit,
    which is doing work on behalf of a stored procedure (DSNX9TRE),
    should terminate agent connection(s). This APAR is to implement
    the logic of DSNLCTAC to DSNX9TRE, to make sure the agent
    connection(s) are cleared.

    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    If an stored procedure thread is waiting for a reply
    from a remote location, the thread cannot be terminated
    when it goes to EOT. This is because currently in EOT
    processing there is no mechanism to terminate the TCP/IP
    connections and therefore the cancel operation
    that causes the EOT cannot be fully honored.
    DSNX9TRE
    

Problem conclusion

  • DB2 code has been enhanced so that it can terminate the
    connections in case the thread is in DDF waiting for reply.
    This will allow DB2 to complete the stored procedure thread
    termination.
