IC88180: WEBSPHERE MQ FILE TRANSFER EDITION 7.0.4 TRANSFERS TAKE TOO LONG TO PROCESS WHEN THE DESTINATION AGENT REACHES CAPACITY

WebSphere MQ File Transfer Edition V7.0 Fix Pack 7.0.4.3

APAR status

• Closed as program error.

Error description

• When the destination FTE agent reaches capacity, transfers
  cannot be processed. Messages fill up the source FTE agent.
  The destination agent is restarted but the transfers remain
  on the senders STATE queue.
  
  Approximately 100 minutes after the destination agent was
  restarted, the transfers did complete.
  The message from the destination agent was:
  [10/09/2012 17:58:27:604 EST] 00000080 TransferRecei I
  BFGTR0063I: Transfer ID: 123451234512345123451234512345
  entering recovery, immediately, due to recoverable error:
  BFGTR0059I: The transfer receiver timed out waiting for
  data from the source agent.
  
  Transfers should not be delayed for that amount of time if
  there is an interruption to the FTE service.

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of WebSphere MQ File Transfer Edition Version 7.0.4
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM SUMMARY:
  When the destination agent reached its capacity any new
  transfers were not processed and were placed on a list of
  'active' transfers. As the list of 'active transfers' reached
  the maxSourceTransfer limit the transfers that the destination
  agent was attempting to recover could not be processed.
  

Problem conclusion

• This APAR solves the problem by making sure that any new
  transfers that can not be processed due to the destination agent
  reaching its capacity are moved onto an 'inactive' list allowing
  the transfers that the destination agent is expected to be
  allowed to process, are processed.
