Sveral Brokers at once

[mark yoffe <ma...@gmail.com>]

Hi Guys

i wanted to know if it is possible to run several Brokers on the same
machine
or is there a problem with this issuse?


will running several brokers on the same machine be better or worse ?
performence wise?

is there a plan to create a mechanisim which will connect several brokers
and load balance messages betwen them if needed?
some kind of cluster maybe ( not the redundancy features mentioned in one of
the threads)


Regards

Mark

no issues - just set different ports and data directories.

that will depend on your hardware. If you start running high core count 
machines then more than
one broker may benefit you.

yes, there is work in progress with some notes here:

It is possible if you use different port numbers indeed.

If your goal is to achieve high performance/failover you would obviously
run your brokers on several boxes. Talking about the C++ broker it has
been designed for scaling with the number of cpu so you should not
benefit in running several brokers on the box. Regarding the M2.1 java
broker I am not sure about the current cpu scalability but I am sure
Martin will know.

I would paraphrase Carl: 
M2.1 supports client failover so active-passive setup can be setup with 
the type A-P software, cluster-suite, veritus etc... there is active 
-active cluster support work being done currently on the C++ trunk 
broker, there was a cluster module for Java broker, but that is being 
planned to be redone.
