We're currently doing this exact thing. What we ended up having to do was
to create a configuration file in the $JRUN_HOME/bin directory and then
manually kick the JRun instance off telling it where the configuration file
is by using the command line parameter '-config {config filename}'. Once
you've done this, you have to always do so to start that JRun instance off
(the web based GUI tool will start the JRun instance off, but will instead
use the global libraries and resources that were set up for all of the
instances).
So, for instance, we have a JRun server instance named:
jsm-foo
We have a jsm-foo.config file in /opt/java/jrun4/bin with the following
content:
#
# VM configuration
#
# Where to find JVM, if {java.home}/jre exists then that JVM is used
# if not then it must be the path to the JRE itself
#
# If no java.home is specified a VM is located by looking in these places in
thi
s
# order:
#
# 1) JAVA_HOME environment variables (same rules as java.home above)
# 2) bin directory for java.dll (windows) or lib/<ARCH>/libjava.so (unix)
# 3) ../jre
# 4) registry (windows only)
#
java.home=/usr/jdk1.4.1
# Arguments to VM
java.args=-Xms25M -Xmx51m -Djava.awt.headless=true
java.class.path={application.home}/servers/lib,/opt/java/jdbc/oracle/Oracle_
driver_9.2.0.3_jdk_1.4.jar
#
# where to find shared libraries, again use commas to separate entries
java.library.path=
We then have a script we kick off that runs the following command (to start
jsm-foo):
jrun -config jsm.foo.config -nohup -start jsm-foo > ../logs/jsm-foo.out 2>&1
And that's how we're handling multiple JRun configurations on the same
machine.

Subject: JVM settings
Saw a previous post for this with no replies...
Is there any way to have unique JVM settings for each Jrun4 server on a
machine? We have a very small and very large site on one machine and
don't want to have the same heap allocation for both.
thank you!
