Message Bus usage in clustered environment

[15年前 に Charanjeet singh Hora によって更新されました。]

Hi All,

I read about Message Bus capabilities of liferay on Wiki http://www.liferay.com/web/guest/community/wiki/-/wiki/Main/Message+Bus.

It says that

The current implementation doesn't allow to send remote messages.

My question is can we use message bus in clustered environment and if yes then how we can use it?

Please reply me asap.

Thanks

Please let me know if there is update on this. Can we use message bus in a clustered environment in liferay 6.0?

Not that I know of.

However it would be an easy matter of using JMS to join your clustered environments:

• Set up ActiveMQ on all instances.
• Add a message bus listener to get messages from the LMB and publish via JMS.
• Create a JMS listener to receive these messages and publish back to the LMB.

It should be possible. LiveUsers uses the message bus to send message to all the nodes. See messaging-misc-spring.xml to see how it's wired up.

I think what you do is register a ClusterBridgeMessageListener along with your own MessageListener to a destination and the ClusterBridge will broadcast the message to all the other nodes.
