IT41242: MFT Audit Information can incorrectly report DESTINATION_FILE_SIZE as -1 for a recovered transfer request

APAR status

• Closed as program error.

Error description

• Upon failover of a high availability IBM MQ MFT agent, the
  Logger will record DESTINATION_FILE_SIZE=-1 for the  recovered
  managed transfer.  This is even though the transfer is
  successful and has the same SOURCE_CHECKSUM_VALUE and
  DESTINATION_CHECKSUM_VALUE.

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of MQ Managed File Transfer.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  When an MQ Managed File Transfer agent is acting as the
  destination agent for a transfer request containing multiple
  files and the agent is stopped immediately and restarted,
  entered agent recovery or fails over to the standby agent.  It
  is possible that the destination agent completed the one of the
  file items, but did not send the audit information to the
  sending agent.  So that when destination agent recovers the
  transfer request, the audit information can have
  DESTINATION_FILE_SIZE set to -1 and an empty
  DESTINATION_LAST_MODIFIED value.  This results in the transfer
  summary information showing the destination size as -1 and last
  modified value being empty.
  

Problem conclusion

• The code has been changed to make a further attempt to obtain
  the destination size/last modified attribute if available after
  the agent has started.  There are still valid reason why the
  DESTINATION_FILE_SIZE could be -1.  One example would be if the
  destination file has been move by another process.
