IC89944: WEBSPHERE WMQFTE V7 BRIDGE AGENT DOESN'T CLOSE AN FTP SESSION GRACEFULLY

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

• The protocol bridge agent does not perform a user logout
  (i.e., does not send a QUIT command to the FTP(S) server) before
  it disconnects. Some FTP/FTPS servers may handle a client
  closing the connection without logout (QUIT) as an error.
  Therefore when transferring a file to a file server and not
  performing a logout prior to disconnecting may result in the
  file server treating the transfer as a failure and
  subsequently block application access to the transferred file.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of the WebSphere MQ File Transfer
  Edition protocol bridge agent connecting to an FTP or FTPS
  file server.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM SUMMARY:
  The protocol bridge agent of WebSphere MQ File Transfer
  Edition is used to send / receive files to an FTP or FTPS file
  server outside of WebSphere MQ File Transfer Edition network.
  When the transfer has completed, the protocol bridge agent
  closes the connection to the external file server. Before
  closing the connection to the file server, the protocol bridge
  agent did not issue a QUIT command to logout the user used to
  connect to the file server. This caused some file servers,
  that require the FTP client to issue a QUIT command before
  disconnecting, as an error in transmission and to treat a file
  transfer as a failure.
  

Problem conclusion

• A new protocol bridge agent property (that accepts a boolean
  "true" or "false" value) has been created that when set,
  instructs the protocol bridge agent to issue a QUIT command to
  the FTP(S) file server prior to closing the connection to it.
  
  This property is called,
  "protocolBridgeLogoutBeforeDisconnect" and can be set within the
  agent.properties file for the protocol bridge agent by adding
  the line:
  
  protocolBridgeLogoutBeforeDisconnect=true
  
  By default, the value of this new property is false. This
  ensures that the protocol bridge agent will maintain current
  behaviour and disconnect without issuing a QUIT command.
