IC94262: WEBSPHERE MQ MFT V7.5 TRANSFER DOES NOT RESUME AFTER THE PROCESS CONTROLLER IS STOPPED AND THE AGENT IS RESTARTED

WebSphere MQ V7.5 Fix Pack 7.5.0.3

APAR status

• Closed as program error.

Error description

• A WebSphere MQ Managed File Transfer V7.5 file transfer is
  started and then the
  destination agent is stopped immediately while the transfer is
  in flight.
  After a few minutes restarting, the destination agent does not
  continue the transfer causing the transfer to enter into a
  stalled state.

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of WebSphere MQ Managed File Transfer v7.5
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM SUMMARY:
  When a transfer was started and the destination agent process
  was immediately stopped or killed before the transfer completed,
  then the transfer entered a recovery state when the transfer
  acknowledgment timeout was reached (transferAckTimeout *
  transferAckTimeoutRetries).
  
  Once the transfer was in the recovery state, if the
  destination agent was then restarted, then the transfer did
  not continue as expected. The transfer progress would then
  change to a 'stalled' state.
  
  If a new transfer was started then this would run and also
  restart the 'stalled' transfer. If no new transfer was started
  then only restarting the source agent process would allow the
  'stalled' transfer to continue.
  

Problem conclusion

• The WebSphere MQ Managed File Transfer logic has been modified
  to resolve the issue and allow a transfer that has entered
  recovery state to continue automatically once the destination
  agent has restarted.
