Say I have multiple application connected to a single database and these applications use JMS and reside in their own cluster i.e., these applications are in 2 separate cluster. Now I have to create SIBus with cluster scope. My understanding is that if I create a SIBus with cluster scope at any given point in time I will be able to run only 1 messaging engine because of the SIBOWNERO table which can have at max 1 row which would be either of the messaging engine. Since both of my applications will be running and both require dedicated messaging engines and both of them will be pointing to the same database how to achieve the same?  I am aware that this can be achieved with 2 different schemas/database but not sure if it can be done using the same database.
