> Queues
> Queues can import messages, but cannot export them.
> Configuration
> You can configure queue definitions (in the configuration file queues.conf) with the import property that specify one or more external transports.

> • | import instructs tibemsd to import messages that arrive on those transports from Rendezvous, and deliver them to the EMS destination.

> (For general information about queues.conf syntax and semantics, see queues.conf on page 234. You can also configure queues using the administration tool command addprop queue.)
> Example
> For example, the following tibemsadmin command configures the queue myQueue.in to import messages on the transports RV01 and RV02.
> addprop queue myQueue.in import="RV01,RV02"
> Rendezvous messages with subject myQueue.in arrive at tibemsd over the transports RV01 and RV02. EMS clients can receive those messages by subscribing to myQueue.in.
> Import—Start and Stop
> When a queue specifies import on a connected transport, tibemsd immediately begins importing messages to the queue, even when no receivers exist for the queue.
> For static queues (configured by an administrator) tibemsd continues importing until you explicitly delete the queue.
> Wildcards
> Wildcards in the import property obey EMS syntax and semantics (not Rendezvous syntax and semantics); see Destination Name—Syntax and Semantics.
> EMS clients cannot subscribe to wildcard queues—however, you can define wildcards queues in the EMS server for the purpose of property inheritance. That is, you can configure a static queue named foo.* and set properties on it, so that child queues named foo.bar and foo.baz will both inherit those properties.
> If you define a queue that imports foo.*, tibemsd begins importing all matching messages from Rendezvous. As messages arrive, tibemsd creates dynamic child queues (for example, foo.bar and foo.baz) and delivers the messages to them. Notices that tibemsd delivers messages to these dynamic child queues even when no consumers exist to drain them.
