Service integration bus security uses role-based authorization. When messaging security is enabled, users and groups require authority to send and receive messages from the topic space root in a publish/subscribe topic hierarchy. By listing the users and groups in topic space root roles, we can find out who has access to the topic space root for a selected topic space.
Topic space root (/) is the highest level topic in a publish/subscribe topic hierarchy. The hierarchy itself is called the topic space. In this task we use the dmgr console wizard to list users and groups in topic space root roles for a selected root topic.
This task applies to the topic space root only; it does not apply to the topics within the topic space, or to the topic space. To list users and groups in topic roles, refer to List users and groups in topic roles. To list users and groups in a topic space (which is a type of destination), see List users and groups in destination roles.
The users and groups listed in this task have references in the service integration bus security configuration. The list does not include all users and groups that exist in the external user repository.
- Log into the dmgr console.
- Click Service integration -> Buses -> security_value -> [Authorization Policy] Manage topic access roles
Results
The Topic space root panel lists all the users and groups in topic space root roles for the selected bus.
We can administer the role type assignments for the users and groups displayed.
