EMS Destination Features

TIBCO Enterprise Message Service allows you to configure destinations to enhance the functionality of each messaging model.

The EMS destination features allow you to:

  • Set a secure mode for access control at the queue or topic level, so that some destinations may require permission and others may not. See Destination Control.
  • Set threshold limits for the amount of memory used by the EMS server to store messages for a topic or a queue and fine-tune the server’s response to when the threshold is exceeded. See flowControl and overflowPolicy.
  • Route messages sent to destinations to other servers. See Routes.
  • Create bridges between destinations of the same or different types to create a hybrid messaging model for your application. This can be useful if your application requires that you send the same message to both a topic and a queue. For more information on creating bridges between destinations and situations where this may be useful, see Destination Bridges.
  • Control the flow of messages to a destination. This is useful when message producers send messages much faster than message consumers can receive them. For more information on flow control, see Flow Control.
  • Exchange messages with TIBCO FTL. Queues can receive messages. Topics can either receive or send messages. See Interoperation with TIBCO FTL.
  • Set queues to be exclusive or non-exclusive. Only one receiver can receive messages from an exclusive queue. More than one receiver can receive messages from non-exclusive queues. See exclusive.
  • Specify a redelivery policy for queues. When messages must be redelivered, you can specify a property on the queue that determines the maximum number of times a message should be redelivered. See maxRedelivery.
  • Trace and log all messages passing through a destination. See trace.
  • Include the user name of the message producer in the message. See sender_name and sender_name_enforced.
  • Administrator operations can use wildcards in destination names. The wildcard destination name is the parent, and any names that match the wildcard destination name inherit the properties of the parent. See Wildcards.
  • Use the store property to cause messages sent to a destination to be written to a store file. Set the destination store to store=$sys.failsafe to direct the server to write messages to the file synchronously and guarantee that messages are not lost under any circumstances. See store for more information.
  • Specify that a consumer is to receive batches of messages in the background to improve performance. Alternatively, you can specify that queue receivers are to only receive one message at a time. See prefetch for more information.
