I am not into FUD. I just want to know if a JBoss JINI based cluster is
just a vanilla install on a bunch of Linux nodes, or if it requires a
sysadmin to actually change the networks configurations of all the node
(something that is not vanilla).
As it is now you can basically take a RedHat CD, install OS, download a
JDK, download JBoss. And then you are off. I really do like that
simplicity (especially compared to how complicated it has allwas been to
download the apache source for example and get it up an working - and
hey I have done that plenty of times).
So, just a simple question. Would the following work?
Install RedHat on 2 linux boxes (vanilla install).
Install JDK on both boxes
Install JBoss on both boxes.
Possibly doing some simple JBoss configuration.
Start the JBoss:es, and clustering is on.
Would JINI based clustering work here, or would I have to do some more
steps?
If you say that this will work, fine, and then I would really like to
have JINI in JBoss (then I could start using JavaSpaces - which is a
concept I really like).
Please Richard, I am not out to fight.
