(For general information about topics.conf syntax and semantics, see
topics.conf on page 266. 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 messages on the transports
RV01 and
RV02, and to
export messages on the transport
RV02.
Rendezvous messages with subject myTopics.news arrive at
tibemsd over the transports
RV01 and
RV02. EMS clients can receive those messages by subscribing to
myTopics.news.
EMS messages sent to myTopics.news are exported to Rendezvous over transport
RV02. Rendezvous clients of the corresponding daemons 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 (which is identical to Rendezvous syntax and semantics); see
Destination Name—Syntax and Semantics.
You can import and
export TIBCO Rendezvous certified messages (
tibrvcm transport) to EMS topics. Rendezvous certified transports guarantee message delivery.
tibrvcm transports can store information about subjects in a ledger file. You can review the ledger file using an administration tool command; see
show rvcmtransportledger on page 169).
