A guess,

but do green threads show up in your monitoring?

if sun uses green by default, but blackdown uses native, you may not see the
green as they are internal.

Subject: workers - loadbalancing


I am currently working on a virtual hosting solution for JSPs / Java
Servlets for my company
fyi: i am using redhat 6.2, tomcat 3.2 beta6 (eagerly awaiting the final
3.2) and the SUN JDK 1.2.2 as the platform for all of this

i am doing all fine configuring virtual hosts and i think i have
(almost) all security issues covered;

the one thing that confuses me about tomcat and / or the JDK i use is
the following:

isn't tomcat supposed to spawn more than one process when configuring
worker.ajp13.lbfactor=10 for example ? or did i misunderstand the
(rather scarce :-) documentation ?
somehow i think that this depends on the JDK that is used:
in the beginning, when i was still experimenting with (apache)jserv and
different java servlets, i used blackdown's jdk 1.2.2, and every time i
restarted apache and therefore the servlet engine / container, at least
4 or more java processes were spawned
but using the same configuration and instead of JDK from blackdown using
SUN's java development kit, only one! process was spawned from the
start! - the same now with tomcat (although i havent tried it with any
other JDK than SUN's yet, i must admit)

Or did i misunderstand the whole issue, and the loadbalancing is done in
some other way ?

I hope someone can shed some light on this!
