Tibco RV vs Tibco EMS

March 28th, 2006, 20:39.

I’ve stumbled upon an article on a blog about Tibco RV vs Tibco EMS. It’s a short review of how RV and EMS compare. Some of the shortcomings that have been mentioned in the article are not really valid, yet there are others that should, I think, be addressed. I’d start with the comparison of RV and EMS:

Rendezvous or RV for short is a technology that brought TIBCO it’s fame. It’s native implementations for many platforms as well as great speed made it perfect choice for tracking real time data: stock tickers, telecommunications, etc…

However, it’s great lack was in certifiable message delivery. By default, it uses a communication mode called “Reliable RV” - and the fun is that it’s a complete misnomer. There’s nothing reliable about it. There are further extensions of RV known as Certified Messaging (RVCM) which use sender based temporary files to raise delivery reliability.

EMS on the other hand is seeing more and more use in TIBCO’s platform. It’s an implementation of the Java Messaging Service (JMS). It is getting more and more penetration into the TIBCO landscape. By now every TIBCO adapter can communicate using EMS along with RV. Any of the custom adapters you might have developed with Adapter SDK are also easy to switch to EMS communication.

The basic model for communication of the EMS system is the so called hub and spoke. The hub is represented by the central EMS server, while the spokes are clients which produce to or consume messages from the server. EMS however, offers some features that I am not aware exist in other JMS implementations.

First off, the EMS servers can be installed on several machines and controlled via the TIBCO Administrator interface or via Hawk. This concept extends even more. If you install several servers, you can load balance messaging queues and topics between the servers, easing off the traffic from loaded nodes.

One feature that I particularly love is the ability to make EMS servers run in fault tolerant clusters. If you combine this feature with a network area storage solution for the data files, you can create a near-instantaneous, fully reliable messaging platform.

Rendezvous is getting old. Lately I’ve been witness to more and more core TIBCO components offering EMS functionality along with RV. It is my oppinion that in the long run, TIBCO will choose to use EMS over RV for it’s primary messaging platform.

Give EMS a try and I’m sure you’ll like it.
