IT19530: BFGBR0062E error intermittently written to agent event log

APAR status

• Closed as program error.

Error description

• An MQ V9.0.0.0 Managed File Transfer protocol bridge agent is
  acting as the source agent for managed transfers.
  Intermittently, the agent writes the following error into it's
  event log (output0.log):
  
  BFGBR0062E: An internal error has occurred. Request for session
  container for transfer Id FTETransferReference

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of the MQ V9 Managed File Transfer
  component who have protocol bridge agents that:
  
  - Act as the source agent for managed transfers.
  - Have been configured to use a ProtocolBridgeProperties.xml
  file that does not contain a <defaultServer> entry.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  When a protocol bridge agent is acting as a source agent for a
  managed transfer and receives a new managed transfer request, it
  performs some processing of that request to determine the
  transfer items that need to be included in the managed transfer.
  Once the list of transfer items has been created, the agent will
  start the managed transfer.
  
  If a transfer item contains a file path that is prefixed by a
  file server name, as shown below:
  
  server1:/home/user/file.txt
  
  then the protocol bridge agent will look in the
  ProtocolBridgeProperties.xml file for an entry for '"server1"
  and connect to that server. However, if a transfer item contains
  a file path that does not start with a file server name, like
  this:
  
  /home/user/file.txt
  
  the agent will assume that the item resides on the default file
  server, as defined by the <defaultServer> entry in the
  ProtocolBridgeProperties.xml file.
  
  If the transfer item did not start with a file server name, and
  the ProtocolBridgeProperties.xml file did not contain a
  <defaultServer> entry, then the agent would generate an invalid
  transfer item for the managed transfer. When the agent started
  processing the managed transfer, it was unable to determine
  which file server the transfer item was on. This caused the
  managed transfer to fail and the agent to report the following
  internal error in it's event log (output0.log):
  
  BFGBR0062E: An internal error has occurred. Request for session
  container for transfer Id FTETransferReference
  [endPointType=SENDER......bridgeFileServerProtocol=null]
  occurred when it is not present.
  

Problem conclusion

• The MQ V9 Managed File Transfer component has been updated so
  that if a protocol bridge agent:
  
  - Receives a managed transfer request containing a transfer item
  that does not start with a file server name
  - And the ProtocolBridgeProperties.xml file for the agent does
  not contain a <defaultServer> entry.
  
  then the managed transfer is marked as "Failed" with the
  following error:
  
  BFGIO0410E: The protocol server name has not been specified, and
  no default protocol server has been defined for the protocol
  bridge.
