Error description

  • Due to connection error to the federated target, Admin thread
    came down.  So any further commands to the program (like stopq /
    startq) would not be accepted since it is the Admin thread's
    responsibility.  The browser thread got a connection error while
    updating IBMQREP_RECVQUEUES table, hence it could not update the
    state to I after ASN7627E was issued.  We can take a bug that
    for federation targets, if the admin thread and all browsers get
    an error and come down, regardless of term, QAPPLY is able to
    gracefully come donw.
    

Local fix

Problem summary

  • The reason was that the error code from admin
    thread was not getting propagated to the main thread for the
    program to stop.
    

Problem conclusion

  • The problem has been fixed to honor
    connection errors from Admin thread and monitor threads bringing
    Q Apply down.  For federated target, if term=N, Q Apply may
    still come down depending on the type of sqlcode returned by the
    federation server whether it is a connection error or a generic
    error code.
    

Temporary fix
