Securing links between messaging engines
For a mixed-version bus, when security is enabled, you must define an inter-engine authentication alias so that the messaging engines can establish trust.
Before you begin
- It exists in the user registry.
- It is used only for messaging engine to messaging engine authentication.
- It has not been added to the bus connector access role.
About this task
If you have a secure, mixed-version bus, you must define
an inter-engine authentication alias to prevent unauthorized messaging
engines from establishing a connection. Messaging engines use the
inter-engine authentication alias to establish trust in the following
scenarios:
- A WebSphere® Application Server Version 6 messaging engine initiates a link with a Version 7.0 or later messaging engine.
- A Version 7.0 or later messaging engine initiates a link with a Version 6 messaging engine.
If you add a server or cluster as a bus member, if that action creates a mixed-version bus, you define an inter-engine authentication alias during that task, and you do not need to perform this task.
Procedure
- In the navigation pane, click .
The bus security configuration panel for the corresponding bus is displayed.
- In the Inter-engine authentication alias field, select an authentication alias.
- Click OK.
- Save your changes to the master configuration.
