1. question on multiple clusters sharing the same port
manik Feb 8, 2011 8:07 AM (in response to yelin666)Yes, a unique port for each cluster is definitely recommended. On some platforms (certain Unix versions, some Windows servers) not using a unique port causes weird crosstalk issues as well.

3. question on multiple clusters sharing the same port
manik Feb 9, 2011 8:15 AM (in response to yelin666)Take a look at the FAQs and wikis on Jgroups' site for details. It's pretty well documented there.

4. question on multiple clusters sharing the same port
yelin666 Feb 9, 2011 10:12 AM (in response to manik)Hi Manik,
I didn't see anything relevant, instead I found the following two articles:
http://community.jboss.org/wiki/Migrationfrommultiplexertosharedtransport
http://www.jgroups.org/manual/html/user-advanced.html
Based on those articles, the JGroups DOES support shared transport. Could you please get Bela or Vladimir (who is the author of the first article) to comment? Is there any performance issue with the shared transport?
Thanks,
Lin

5. question on multiple clusters sharing the same port
galder.zamarreno Feb 17, 2011 6:32 AM (in response to yelin666)Shared transport works particularly well in AS environments where you have multiple Infinispan Cache Manager's in action. JBoss Application Server uses this. I'd suggest looking into what the JBoss AS guys did for AS6 if you can't wait for Bela/Vladimir.
Even thouhg http://community.jboss.org/docs/DOC-12460 is oriented for JBoss Application Servers, the concepts are the same and you need to apply the same rules to the JGroups channels backing Infinispan if you wanna keep them separate.

6. question on multiple clusters sharing the same port
yelin666 Feb 17, 2011 2:28 PM (in response to galder.zamarreno)Thanks for the response. I got a response from Bela on JGroups forum, and clear about it.
