Multiple Rice Instances on the Same Server

Given:

You have multiple Tomcat instances, each with different shutdown and AJP ports
You have an Apache server

You want to host multiple Rice Standalone Servers on the same server like so:

Rice Standalone Server	CATALINA_HOME	Rice Configuration	application.url	Shutdown port	AJP port
A	/usr/share/tomcatA	/usr/local/rice/instanceA/rice-config.xml	https://rice-sandbox.sampleu.edu/instanceA	8500	8010
B	/usr/share/tomcatB	/usr/local/rice/instanceB/rice-config.xml	https://rice-sandbox.sampleu.edu/instanceB	8501	8011

Apache Mod Proxy AJP Configuration

MOD AJP

/etc/httpd/conf.d/proxy_ajp.conf

...
ProxyPass /instanceA ajp://localhost:8010/instanceA
ProxyPass /instanceB ajp://localhost:8011/instanceB
...

Rice Standalone Server Instance A Configuration

Rice Configuration Home

/usr/local/rice/instanceA

Rice Configuration

/usr/local/rice/instanceA/rice-config.xml

<param name="server.url">rice-sandbox.sampleu.edu</param>
<param name="machine.url">rice-sandbox.sampleu.edu</param>
<param name="application.url">http://${server.url}/${nonroot.context}</param>
 <!-- change these two lines -->
<param name="nonroot.context">instanceA</param>
<param name="rice.config.path">/usr/local/rice/instanceA</param>

CATALINA_HOME

/usr/share/tomcatA

Catalina Properties

/usr/share/tomcatA/conf/catalina.properties

# Kuali RICE configuration path for Instance A
# Necessary to allow multiple rice installations on a single server
additional.config.locations=/usr/local/rice/instanceA/rice-config.xml

Tomcat Configuration

/usr/share/tomcatA/conf/tomcat5.conf

CATALINA_OPTS="-Xms128m -Xmx256m -XX:PermSize=64m -XX:MaxPermSize=128m
export CATALINA_OPTS

*(optional) Tomcat Configuration in DEBUG mode *

/usr/share/tomcatA/conf/tomcat5.conf

CATALINA_OPTS="-Xms128m -Xmx256m -XX:PermSize=512m -XX:MaxPermSize=128m -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"
export CATALINA_OPTS

Tomcat Connectors

/usr/share/tomcatA/conf/server.xml

<!-- A "Server" is a singleton element that represents the entire JVM,
     which may contain one or more "Service" instances.  The Server
     listens for a shutdown command on the indicated port.
...
<Server port="8500" shutdown="SHUTDOWN">
...
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="8010" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />
