IC98612: WMQ FTE MESSAGE TO FILE TRANSFER DOES NOT TRANSFER ALL MESSAGES IN A GROUP IF THE GROUP IS OUT OF SEQUENCE

WebSphere MQ File Transfer Edition V7.0 Fix Pack 7.0.4.4
WebSphere MQ V7.5 Fix Pack 7.5.0.4

APAR status

• Closed as program error.

Error description

• Working with WebSphere MQ File Transfer Edition V7.0.4. The FTE
  resource monitor " message to file transfer " does not work
  properly, if message grouping is used. In case messages are put
  on a queue in an unordered manner, where messages that belong to
  a messageGroup are put on the the queue mixed with messages that
  do not belong to a messageGroup, not all messages are written to
  the final destination.

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of WebSphere MQ File Transfer Edition
  7.0.4 and WebSphere MQ Managed File Transfer 7.5 who are using
  the message to file transfer feature to transfer message groups.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM SUMMARY:
  When specifying a message to file transfer the user can define
  the group id of the message group that will be transferred.
  The WebSphere MQ FTE/MFT agent should then wait until the
  complete group of messages is available on the queue before
  reading them off the queue.
  
  If first message defined in the group was not the first
  message physically on the queue then the FTE/MFT agent would not
  read this message. The FTE/MFT agent incorrectly read the
  grouped message closest to the front of the queue rather than
  the first logical message in the group on the queue. The
  result is that the file at the destination side would only
  contain a subset of the expected message data, the transfer
  log would report no error and the message count contained within
  the transfer log would be correct for the data that was
  transferred i.e. if a message group contained 10 messages but
  only 8 messages were transferred then the message count would be
  8.
  

Problem conclusion

• The FTE/MFT agent has been modified to retrieve the first
  logical message in the group when processing a message to file
  transfer that is using message groups.
