Import Issues


This section presents issues associated with importing messages to EMS from Rendezvous—whether on a topic or a queue.

Import Destination Names Must be Unique

When a topic and a queue share the same name, at most one of them may set the import property. For example, if a topic foo.bar and a queue foo.bar are both defined, only one may specify the import property.

JMSReplyTo

When tibemsd imports and translates a Rendezvous message, it sets the JMSReplyTo field of the EMS message to the value of the Rendezvous reply subject, so that EMS clients can reply to the message.

Usually this value represents a Rendezvous subject. You must explicitly configure tibemsd to create a topic with a corresponding name, which exports messages to Rendezvous.

Guaranteed Delivery

For full end-to-end certified delivery from Rendezvous to EMS, all three of these conditions must be true:

  • Rendezvous senders must send labeled messages on RVCM transports.
  • The transport definition must set topic_import_dm or queue_import_dm (as appropriate) to TIBEMS_PERSISTENT.
  • A durable subscription for the EMS topic or queue must exist.
