You can configure the properties of a messaging engine
in the administrative console. You can select whether the messaging
engine is started automatically when its associated application server
is started, how many messages it can deal with, and target groups
that the engine can join.
About this task
To
configure the properties of a messaging engine, use the administrative
console to complete the following steps.
Procedure
- In the navigation pane, click .
- In the content pane, click the name of the bus to which
your messaging engine belongs.
- Under Topology, click Messaging
engines. A list of messaging engines
is displayed.
- Click the messaging engine name.
- Under General properties, specify
the following properties:
- Description
- An optional description for the messaging engine, for administrative purposes.
- Initial state
- The initial state determines whether the messaging engine is started automatically. If
this property is selected, the messaging engine starts automatically
when its associated application server is started. Until the messaging
engine starts, it is unavailable.
- High message threshold
- The maximum total number of messages that the messaging engine can place on its message points. When the messaging engine is created,
the high message threshold of the bus is used to set the default value
for this property.
When a message point is created on this messaging
engine, the value of this property is used to set the default high
message threshold for the message point.
- Target groups
- A list of target groups that the messaging engine should join.
Custom target groups are a type of target group used by JMS connection
factories. When an application creates a connection to a service integration
bus, it uses connection factory properties to indicate suitable messaging
engines to connect to. When a target type of "Custom" is specified
in the connection factory targetType property, the application will
be connected to one of the messaging engines in the specified custom
target group. A particular messaging engine is selected from the
group according to the other connection factory properties that have
been specified.
- Click OK.
- Save your changes to the master configuration.
