Use this page to view the configuration of a messaging engine. A messaging engine is a component, running inside a server, that manages messaging resources for a bus member. Applications are connected to a messaging engine when accessing a service integration bus.

To view this administrative console page, do the following:
  1. Click Service integration > Service Integration Bus Browser.
  2. In the navigation tree pane, expand the bus_name tree, and then expand the bus_member subtree.
  3. From within the bus_member tree, click the name of messaging engine.

All fields on this page are read only. To edit the properties of a messaging engine, use the version of this page available by clicking Service Integration > Service Integration Bus Browser > [content pane] bus_name > [content pane] Messaging engines > [content pane] engine_name.

Name

The name of the messaging engine

UUID

The universal unique identifier assigned by the system to this messaging engine.

Description

An optional description for the messaging engine.

Initial state

Specifies whether the messaging engine is started automatically.

The selection list contains the following options:
Started
When the associated application server is started, the messaging engine is started and is available to process messages.
Stopped
When the associated application server is started, the messaging engine is stopped and is not available to process messages.

Message store type

The type of message store used: file store or data store. Once the messaging engine has been created, the type cannot be changed.

High message threshold

The maximum number of messages 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 of this property for the messaging engine itself. In turn, 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 with which the messaging engine can register.

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 specify suitable messaging engines to connect to. When a target type of Custom is specified in the connection factory targetType property, the application connects to one of the messaging engines in the specified target group. A particular messaging engine is selected from the group according to the other connection factory properties that have been specified.

Bus name

The name of the service integration bus on which this messaging engine is configured.

Bus UUID

The universal unique identifier of the service integration bus on which this messaging engine is configured.
