I just finished setting up a group of RedHat Linux
boxes and have succesfully run distributed tests on
them.  I wanted to share some lessons learned:

1) Hosts:
a) Get rid of the server name alias to 127.0.0.1. 
Only alias the server name to the NIC's address.
b) Make sure all of your machines have each other in
their local host files.  Make a master and copy it.

2) RH 7.x has a /usr/bin/java.  Rename it.
3) RH 8.x not only has /usr/bin/java, but also
/usr/bin/rmiregistry.  Rename it.

4) The GUI must be the same build as the servers.  OS
doesn't seem to matter (I've used Win2K, RH8.0, RH7.2)
- It's Java!

5) I'm using Sun's J2SDK-1.4.1_01 on all machines
without obvious problems.  I wouldn't mix JVMs.

I am just starting a distributed load test and I'm
sure I will learn more.  I'm now looking into
performance tweaks (memory).
