Pros and Cons of running Multiple JBoss instances on single server.

bensonfungjava Jan 14, 2011 4:27 AM

Hi,

There is a debate within our team regarding the running multiple jboss instances on single server.

One side favor to use separate JBOSS distribution on different location of the filesystem on the single server.

Another side favor to use 1 JBOSS distirubtion but multiple instances(i.e. duplicate default folder) on the single server.

What are the pros and cons between these two configurations? Please advise

Thanks

IMHO this is just a organisational issue because the posibillity of errors is not really different.

We decide to separate complete to avoid confusion.
We also have your own start script and store the PID of the JVM and a customized installer to adapt JBoss and add our app.

Duplicate the server (BTW I'll allways use my own config insted of default/all/etc.)
- will save disc space (which is not expensive)
- can error prone for stop/restart

Complete separation
- more effort in case of JBoss library updates (JB 5.1 use a common lib folder, JB4 a server/XY/lib)
- no difference whether same or other system

Is there any impact on the server resources?

No,
nevertheless how you start each JBoss instances is started with its own JVM.
