[Cosmo] Cosmo and Jrockit oh so good!

[Brian Kirsch]

Hi Jared,
To facilitate performance / bug testing between Cosmo 0.2.4 and Chandler 
I would like to have a server on cosmodemo (halua)
that is leveraging the jrockit vm.

I have gone ahead and installed jrockit, cosmo0.2.4 and an environmental 
config script in my local halua environment /home/bkirsch.

I have set my .profile to include:

JAVA_HOME=/home/bkirsch/jrockit
export JAVA_HOME

COSMO_HOME=/home/bkirsch/cosmo-0.2.4
export COSMO_HOME

JAVA_OPTS="$JAVA_OPTS -Xns:750m -Xms:1000m -Xmx:1000m"
JAVA_OPTS="$JAVA_OPTS -Xgcpause"
JAVA_OPTS="$JAVA_OPTS -Xgcreport"
JAVA_OPTS="$JAVA_OPTS -Xverbose:memory"
JAVA_OPTS="$JAVA_OPTS -Xverboselog:/home/bkirsch/gc.log"
JAVA_OPTS="$JAVA_OPTS -Xmanagement"

export JAVA_OPTS

PATH=$JAVA_HOME/bin:$COSMO_HOME/bin:$PATH


The server when started via cosmoctl has the following configuration:


/home/bkirsch/jrockit/bin/java -Xns:750m -Xms:1000m -Xmx:1000m -Xgcpause 
-Xgcreport -Xverbose:memory -Xverboselog:/home/bkirsch/gc.log 
-Xmanagement -server -Dcom.sun.management.jmxremote 
-Dical4j.unfolding.relaxed=true -Dderby.stream.error.file=logs/derby.log 
-Dderby.infolog.append=true 
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager 
-Djava.endorsed.dirs=/home/bkirsch/cosmo-0.2.4/tomcat/common/endorsed 
-classpath 
:/home/bkirsch/cosmo-0.2.4/tomcat/bin/bootstrap.jar:/home/bkirsch/cosmo-0.2.4/tomcat/bin/commons-logging-api.jar 
-Dcatalina.base=/home/bkirsch/cosmo-0.2.4/tomcat 
-Dcatalina.home=/home/bkirsch/cosmo-0.2.4/tomcat 
-Djava.io.tmpdir=/home/bkirsch/cosmo-0.2.4/tomcat/temp 
org.apache.catalina.startup.Bootstrap start

What I would like to do is kill of some of the current running cosmo 
java processes and have this new jrockit vm Cosmo running on 8080 for 
load testing against Chandler.

This will allow us to pinpoint any major points of failure between Cosmo 
and Chandler as well as do in depth performance and memory profiling.



Thoughts?

-Brian
