    Note

    Note the following for the Topic name:

    • Topic name can starts with any of the following: * , alphanumeric characters (a-z, A-Z or 0-9). These can be used any number of times delimited by dots. 
    • Topic name can end with the following: * , alphanumeric characters, hash (#).  
    • The “/” symbol (TENANT_SEPARATOR) can only be used to separate the tenant domain from the topic name when creating topics/subscribing to topics from external clients.
    • The colon (":") can be used in Topic names if the <allowStrictNameValidation> property is set to false in the broker.xml file (stored in the <MB_HOME>/repository/conf folder). This is only applicable for AMQP.
  4. Now you need to grant permissions for users in your system to publish and subscribe to the topic you are creating. You will be granting these permissions to users based on the user's role. As shown below, all the user roles in your tenant domain will be listed. You can select the relevant check box against each role:
    • If the Subscribe check box is selected, the users linked to the role has permission to subscribe to the topic.
    • If the Publish check box is selected, the users linked to the role has permission to publish information to the topic.
    If you want to create new user roles for topic subscription and publishing see the documentation on creating users and roles.
