System queues and the system topic

IBM® MQ Managed File Transfer has a number of system queues and one system topic that are for internal use only.

Any queues with a name beginning SYSTEM.FTE are internal system queues for Managed File Transfer (MFT). Do not delete these queues, as doing so prevents IBM MQ MFT from working correctly.

If an agent is participating in message-to-file or file-to-message transfers, the definition of the SYSTEM.FTE.STATE.agent_name queue might need to be modified to allow these managed transfers to take place. For more information on this, see Guidance for setting MQ attributes and MFT properties associated with message size.

Attention: You should not change the definitions of the other system queues.

Also, do not modify or delete the SYSTEM.FTE topic as this is also for internal use only.

Temporary queues

IBM MQ Managed File Transfer creates temporary queues for a number of purposes. The name of each queue starts with WMQFTE. by default. (The period is part of the default prefix.) If you want to change this prefix, you can use the dynamicQueuePrefix property in the command.properties file or the coordination.properties file or both. The property in the command.properties file is used to set the prefix of temporary queues that are created for responses to commands that require a response from the agent. The property in the coordination.properties file is used to set the prefix of temporary queues that are created for other purposes; for example, the WMQFTE.FTE.TIMECHCK.QUEUE, where WMQFTE. is the value defined by the dynamicQueuePrefix property.
