Embedded Tomcat Java Heap Size

[Geng, Kelly]

Hello All,

Does anyone know how to adjust the Java heap size if you run the embedded tomcat for CAS5? We tried to update it in the build.cmd file in the overlay project, and tried to add -Xms and Xmx flags in the java command line, but none seems to take effect. 

Thanks!

We use systemd to run our CAS service. Here's our configs for running CAS with a larger heap:

/etc/systemd/system/cas.service:

[Unit]

Description=CAS Webserver

After=syslog.target

[Service]

EnvironmentFile=/etc/sysconfig/cas

User=cas

ExecStart=/bin/java $JAVA_OPTS -jar /opt/cas/cas.war

SuccessExitStatus=143

[Install]

WantedBy=multi-user.target

/etc/sysonfig/cas:

JAVA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8 -server -Xms1g -Xmx6g -XX:-UseGCOverheadLimit -XX:+UseConcMarkSweepGC -XX:-UseCompressedOops"

I don't recall if the embedded tomcat uses the JAVA_OPTS environment variable or the command line flags.
