Topics can both export and import messages. Accordingly, you can configure topic definitions (in the configuration file topics.conf
) with import
and export
properties that specify one or more external transports:
(For general information about topics.conf
syntax and semantics, see topics. You can also configure topics using the administration tool command addprop topic
.)
For example, the following tibemsadmin
commands configure the topic myTopics.news
to import and export messages on three transports.
SmartSockets messages with subject /myTopics/news
arrive at tibemsd
over the transports SS01 and SS02. EMS clients can receive those messages by subscribing to myTopics.news
.
EMS messages sent to myTopics.news
are exported to SmartSockets over all three transportsSS01, SS02 and SS03. SmartSockets clients of the corresponding RTservers can receive those messages by subscribing to /myTopics/news
.
When a topic specifies import on a connected transport, tibemsd
imports messages only when the topic has registered subscribers.
Wildcards in the import
and export
properties obey EMS syntax and semantics (not SmartSockets syntax and semantics); see Destination NameSyntax and Semantics.
