Hi, there.

If I replace Software AG’s broker by some other provider’s JMS implementation, would I notice the difference? What would it consist of?

Cheers.

You will have like tonnes of issues. Please understand that the WmBroker has been designed to fit in the webMethods architecture seemlessly and it is the messaging backbone of the entire webMethods platform. If you go about changing that the entire messaging system on webMethods can get impacted. The impact point could be Triggers, MWS, IS Doucment Types, Clients etc.

You should be able to use any JMS provider instead of broker. Though you cannot use it as wM Broker directly, and will not be able to use regular broker related services, all required functionality (like pub-sub model, guaranteed delivery etc) can still be achieved through JMS.
