Multiple brokers on the same host
Hi -
trying to run multiple brokers on one host for testing I ran into issues of
port 9999 already being used. I created a new properties file for each
broker and changed the regular broker port to listen on a different port
(btw - if using ZK for service registration / discover, is there any reason
as to why one would have to use a fixed port?) - however for some reason
RMI is requiring port 9999 - what's that used for? Is there a properties
flag that changes this?
Thanks
Flo

Never mind - this was my negligence - sorry for the spam.

Thanks - I forgot that there's JMX being used... makes all sense now!

You can override that with the JMX_PORT environment variable. So something
like:
env JMX_PORT=10000 [server start script]
