Buses [Settings]


Overview

A service integration bus is a group of interconnected servers and clusters, known as bus members, which host messaging engines to which applications can attach.

To configure a service integration bus, go to...

Service integration | Buses | bus_name


Configuration tab

These property values are preserved even if the runtime environment is stopped then restarted.


General Properties


Name

The system is unable to differentiate between upper and lowercase characters in bus names. We cannot create two buses named FOO1 and foo1 because the names will not be recognized as different to each other.

Required No
Data type String


UUID

Universal unique identifier.

Required No
Data type String


Description

An optional description for the bus, for administrative purposes.

Required No
Data type Text area


Inter-engine transport chain

The transport chain used for communication between messaging engines in this bus. Must correspond to one of the transport chains defined in the settings for...

Messaging engine inbound transports

All servers automatically have a number of transport chains defined to them, and it is also possible to create new transport chains. The default transport chain is InboundBasicMessaging.

Required No
Data type String


Discard messages

Whether messages on a deleted message point should be retained at a system exception destination or can be discarded.

Required No
Data type Boolean


Configuration reload enabled

Select this option to enable certain changes to the bus configuration to be applied without requiring the messaging engines to be restarted.

Select this option to enable automatic update of configuration information about all the messaging engines on the bus.

Changes to bus destinations or mediations are applied when destinations or mediations are added to or removed from the bus.

Changes to the modifiable configuration information for any foreign bus connections are also updated automatically. The time when these changes take effect varies:

Foreign Bus Connection properties

Immediately

WebSphere MQ link properties

On channel restart, except Description (immediately), and Initial State (on messaging engine restart)

MQ sender channel properties

On channel restart, except Initial State (on messaging engine restart or sender channel creation)

MQ receiver channel properties

On channel restart, except Initial State (on messaging engine restart or receiver channel creation)

Publish/subscribe broker profile (0 to n) properties

Immediately

Service integration bus link properties

On link restart, except Description (immediately), and Initial State (on messaging engine restart or link creation)

The Configuration reload enabled property also needs to be set on the SIB Service of the application server. To ensure that dynamic configuration updates are made on an application server, click Servers -> Server Types -> WebSphere application servers -> server_name

-> [Server messaging] SIB service to display the Application Servers window, then select Configuration reload enabled.

To ensure that dynamic configuration updates are made to each node, click System administration -> Console Preferences to display the Console Preferences window then select Synchronize changes with Nodes.

Required No
Data type Boolean


Default messaging engine high message threshold

A threshold above which the messaging system will take action to limit the addition of more messages to a message point.

When a messaging engine is created on this bus, the value of this property is used to set the default high message threshold for the messaging engine.

Required No
Data type Long
Range 1 through 9223372036854775807



Bootstrap members

Bus members, servers and clusters that client applications can target to bootstrap into the given bus.

Select one of the following bootstrap member policies to limit the range of available bootstrap members:

All members of the cell with the Service Integration Bus Service enabled

This the default policy. Use any server in the cell that has the Service Integration Bus Service enabled to service bootstrap requests.

Bus members and nominated bootstrap members

Use bus members and nominated cell members to service bootstrap requests.

Bus members only

Use bus members only to service bootstrap requests.

Required No

Messaging engines

A messaging engine manages bus resources and provides a connection point for applications.

Foreign bus connections

A foreign bus is another bus with which this bus can exchange messages.

Bootstrap members

Bus members, servers and clusters that client applications can target to bootstrap into the given bus.


Destination resources

Destinations

A bus destination is a logical address within a service integration bus.

Mediations

Mediations define the information needed by a messaging engine to perform the mediation processing for associated destinations.


Services

Inbound services

An inbound service describes the web service enablement of a service destination. It provides the configuration of endpoint listeners within a port.

Outbound services

An outbound service represents a WSDL-described service.

WS-Notification services

A WS-Notification service provides access to service integration bus resources for web services publish and subscribe clients.

Reliable messaging state

Use this page to view and manage the WS-ReliableMessaging runtime state.


Additional Properties

Custom properties

Arbitrary name-value pairs of data, where the name is a property key and the value is a string value that can be used to set internal system configuration properties. Defining a new property enables you to configure a setting beyond that which is available in the admin console.

Web service gateway instances

A web services gateway allows you to configure specific endpoint listeners and deploy gateway and proxy services to those listeners.

Security

Security of your service integration bus can be managed from here.
