Hornetq cluster replication with 2 live servers

[jcas47]

Hello. I am researching a hornetq cluster solution in which I have 2 wildfly servers that are load balanced by another device (not running wildfly domain). My goal is to have the following:

Wildfly1 running live hornetq node

Wildfly2 running backup hornetq node

Wildfly1 and 2 are both running live Rest application

What I would like to happen is Wildfly1 and Wildfly2 use hornetq on Wildfly1. In the case of a failure, it will begin using hornetq on Wildfly2.

Is this possible?

Is this possible?

Yes, I think it would be possible.  However, container instances are pretty "cheap" so you might be better off separating HornetQ out from the application.

I may have to go with the setup if possible... so maybe you can help shed some light on the errors I am seeing (think regarding to MDB) when trying to accomplish what I posted. Attached are the Widfly1 config, Wildfly2 config, and the error message I am getting on only Wildfly2 when trying to start the service. Wildfly1 starts up fine.

The problem is that your application is relying on resources that are only available when the broker is active.

I would suggest to use colocated HA topology. Wildfly1 would contain live1/backup2 and Wildfly2 live2/backup1. So Wildfly servers contains backup for each other. Normally live servers will form HornetQ cluster. If one of the Wildfly servers is killed then backup on other server activates. I've attached configs for both of the servers.

That is what I am finding out. I think I might start looking the way of shared stores or moving HornetQ out of the container. The end goal would be if Wildfly1 were to go down, Wildfly2 would be able to process those messages. Thank you for your help.
