running two clusters on the same network

[ericl]

Hi,

I'm trying to run two clusters (development / production) on the same network. I've read several suggestions in the forums indicating that I need to change the multi-cast address in cluster-service.xml, ie:

<UDP mcast_addr="228.1.2.3" mcast_port="45566"... to
<UDP mcast_addr="...something else..." ...

this seems easy enough. I was just wondering, is there a way to tell JBoss to grab the value from a System property? I'd like to launch JBoss with, say -Dmcast_addr=... as it would make distinguishing between partitions much easier.



On a related and probably easier note, how do the clients differentiate between the clusters? There's no cluster-service.xml in the client of course, so how do they know which one to use?

Thanks for any help you can offer.

Sincerely,
Eric

No, there's no system property for mcast_addr. The problem is that a JBoss node can be member of multiple clusters, then you wouldn't be able to use a single system prop.
