ABSTRACT OF PROBLEM
___________________
Provide fixes for TPF/MQSeries channel problems


COMMENTS ON PROBLEM
___________________
With  the  Turbo MQ support(PJ27023), several TPF/MQSeries prob-
lems have been uncovered. The problems are:

o   When TPF cycles up to Norm state,  a  receiver  channel  may
    stay  active and no remote sender channel can connect to the
    receiver channel because the receiver channel had never been
    shut down when TPF cycled down to 1052 state.

o   CTL-10 dumps taken out of CMQR during cycle down.

o   ZMQSC START CHL-ALL may not respond with a  message  to  the
    console.

o   When  starting  a  sender channel, if the transmission queue
    associated with the sender channel is not defined, no appro-
    priate error message will be sent to the  operator  console.
    Instead,   MQSC0315I START SENDER CHANNEL SUCCESSFUL will be
    seen.


SOLUTION
________
CMQS has been updated to fix all the problems.

o   Upon cycling TPF up to Norm state, at  start  of  the  local
    queue  manager,  TPF/MQSeries will reset each channel status
    to stopped.  This  will  allow  remote  sender  channels  to
    connect to TPF receiver channels.

o   When  the local queue manager stops, a receiver channel will
    exit. This will avoid CTL-10 dumps.

o   A new message, MQSC0230I will be seen in response  to  ZMQSC
    START CHL-ALL.

o   When starting a sender channel, if its transmission queue is
    not defined, MQSC0338E is sent to the console.
