IC88255: NEW FUNCTION TO ALLOW LARGE MESSAGES TO BE PUT TO A QUEUE WHEN USING FILE-TO-MESSAGE FUNCTIONALITY

WebSphere MQ File Transfer Edition V7.0 Fix Pack 7.0.4.3
WebSphere MQ V7.5 Fix Pack 7.5.0.2
WebSphere MQ v7.5.0.2 Hypervisor for RHEL

APAR status

• Closed as program error.

Error description

• This new function in v7.0.4.3 allows the creation of messages of
  up to 100MB in size when transferring to a single message in a
  file-to-message transfer.
  
  Without this new function the maximum size of a single message
  on a queue in a file-to-message transfer is 33MB.

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users wishing to put large files to a queue using
  file-to-message functionality.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM SUMMARY:
  Due to the design of WebSphere MQ File Transfer Edition, it
  was not possible to put a single file to a single message when
  that file was larger than 33MB.
  

Problem conclusion

• You can now submit a large one file to one message transfer,
  up to a file size of 100 MB. To reduce memory usage for large
  one file to one message transfers, you are recommended to set
  the -qs parameter on the fteCreateTransfer command equal to
  the size of message being written. If you have a file larger
  than 100 MB, and you also specify the -qs parameter on the
  fteCreateTransfer command, the file is split into multiple
  messages.In the case of recovery of binary one file to message
  transfers, the transfer restarts from the point that the last
  checkpoint was written. In the case of recovery of text
  transfers, the transfer restarts from the beginning of the file,
  which might result in an incomplete group of messages on the
  destination queue. When the failed text transfer is restarted, a
  completely new group of messages is written.
  
  The new function for 7.0.4.3 or 7.5.0.2 depending on release
  version must be enabled to take advantage of this new function.
