Administer topic space root roles

Service integration bus security uses role-based authorization. When messaging security is enabled, groups of users require authority to send and receive messages from the topic space root in a publish/subscribe topic hierarchy. By adding and removing users and groups in topic space root roles, we can control access to the topic space root.

Topic space root (/) is also called the virtual root, and it is the highest level topic in a publish/subscribe topic hierarchy. The hierarchy itself is called the topic space, and it is a type of destination. Note these tasks apply only to the topic space root; they do not apply to topics or a topic space. For information about administering topic access roles, refer to Administer topic roles, and for information about administering topic space access roles, see Administer destination roles.

We can add and remove users and groups in the sender and receiver roles for the topic space root. The topic space root can also inherit access in the sender and receiver roles from the topic space, providing the topic space is configured to inherit the default destination roles. For more information about topic inheritance, see Topic security.

For the topic space root roles to have an effect, the Topic Access Check Required check box must be selected in the topic space configuration. For more information, see Configure bus destination properties.
