A topic space mapping allows subscribers on the local topic
space to receive messages published in the foreign topic space. You
can create topic space map entries between two service integration
buses.
About this task
To
map a topic space on a local bus to a topic space on a foreign bus,
use the administrative console to complete the following steps.
Note that for publishing and subscribing between
a service integration bus and a foreign bus that represents a WebSphere® MQ network, you
must define topic mappings on the broker profile associated with the WebSphere MQ link.
Procedure
- In the navigation pane, click .
A list of buses is displayed in the content pane.
- In the content pane, select the bus for which you want
to create topic space map entries, that is, the local bus.
- In the content pane, under Topology,
click Foreign buses. A list
of foreign buses is displayed.
- Select the required foreign bus. This is the
service integration bus that you want the topic space on the local
bus to map to.
- In the content pane, under Additional properties,
click Service integration bus link routing properties.
If this option is not available, but there
is a link titled WebSphere MQ link routing properties,
the foreign bus represents a WebSphere MQ
network rather than another service integration bus, and you do not
need to create topic space mappings.
- In the content pane, under Additional properties,
click Topic space mapping.
- In the content pane, under General properties,
enter a description for the mapping in Description and
click Apply.
- In the content pane, under Additional properties,
click Topic space map entries.
- Click New.
- Specify the mappings as follows:
- Local topic space
- The name of the topic space on this (local) bus that is mapped to the remote topic space on the foreign bus.
- Remote Topic space
- The name of the topic space on the foreign bus that is mapped to the local topic space.
Note: The names of the local and foreign topic space
do not have to match, but the names of the topics must match in both
local and foreign buses.
- Click OK.
- Save your changes to the master configuration.
Results
The remote topic space is mapped to the local topic space.
