Sometimes we may need to add new JVM arguments to Liferay
Portal Tomcat server.
We have different ways to add JVM arguments to server
and here are the options.
Tomcat provided setenv.bat and setenv.sh files
in bin directory and we will add new JVM arguments in these files under “CATALINA_OPTS”
variable.
JVM Argument syntax
-D[ARGUMENT_NAME]=[ARGUMENT_VALUE]
|
Windows Operating System
In Windows Operating system, we have to use setenv.bat
file to add new JVM arguments
Open setenv.bat file in editor and add your JVM
argument as follows and save the file
set
"CATALINA_OPTS=%CATALINA_OPTS% -Djavax.xml.bind.JAXBContextFactory=com.sun.xml.bind.v2.ContextFactory"
|
Make sure we have to keep the %CATALINA_OPTS% always
which means that we are adding new JVM arguments along with existing arguments.
You can also create your custom options and finally
append to “CATALINA_OPTS”
Example:
set
"LIFERAY_OPTS=-Djavax.xml.bind.JAXBContextFactory=com.sun.xml.bind.v2.ContextFactory"
set
"CATALINA_OPTS=%CATALINA_OPTS% %LIFERAY_OPTS%"
|
Unix/Linux Family Operating Systems
Open setenv.sh file in editor and add your JVM
argument as follows and save the file
CATALINA_OPTS="$CATALINA_OPTS
-Djavax.xml.bind.JAXBContextFactory=com.sun.xml.bind.v2.ContextFactory "
|
Make sure we have to keep the $CATALINA_OPTS always
which means that we are adding new JVM arguments along with existing arguments.
You can also create your custom options and finally
append to “CATALINA_OPTS”
Example:
LIFERAY_OPTS="-Djavax.xml.bind.JAXBContextFactory=com.sun.xml.bind.v2.ContextFactory"
CATALINA_OPTS="$CATALINA_OPTS
$ LIFERAY_OPTS"
|
Liferay Portal already have many existing CATALINA_OPTS
and we have to add new JVM argument to existing list.
setenv.bat
Example setenv.bat file in Liferay Portal Tomcat (tomcat-9.0.17\bin)
set
"CATALINA_OPTS=%CATALINA_OPTS% -Dfile.encoding=UTF8
-Djava.locale.providers=JRE,COMPAT,CLDR -Djava.net.preferIPv4Stack=true
-Duser.timezone=GMT -Xms2560m -Xmx2560m -XX:MaxNewSize=1536m
-XX:MaxMetaspaceSize=512m -XX:MetaspaceSize=512m -XX:NewSize=1536m
-XX:SurvivorRatio=7"
set
"CATALINA_OPTS=%CATALINA_OPTS%
-Djavax.xml.bind.JAXBContextFactory=com.sun.xml.bind.v2.ContextFactory"
|
setenv.sh
CATALINA_OPTS="$CATALINA_OPTS
-Dfile.encoding=UTF8 -Djava.locale.providers=JRE,COMPAT,CLDR
-Djava.net.preferIPv4Stack=true -Duser.timezone=GMT -Xms2560m -Xmx2560m
-XX:MaxNewSize=1536m -XX:MaxMetaspaceSize=512m -XX:MetaspaceSize=512m
-XX:NewSize=1536m -XX:SurvivorRatio=7"
CATALINA_OPTS="$CATALINA_OPTS
-Djavax.xml.bind.JAXBContextFactory=com.sun.xml.bind.v2.ContextFactory"

Restart servers then new configuration applies to the
server.
Liferay IDE/Liferay Developer Studio
If you are using Liferay IDE/Liferay Developer Studio
then use server configuration to add new JVM arguments.
Servers View --> Double Click on Liferay Server --> Open Launch Configuration --> Click Arguments --> Edit VM arguments Input
Its editable text area and we can add new variable as
follows and Make sure each argument separated by SPACE.
Restart server then new configuration applies to the
server.
IntelliJ Idea
If you are using IntelliJ Idea Liferay Plugin Developer
Studio then use server configuration to add new JVM arguments
Liferay Server Edit Configuration
Add new JVM arguments in VM Options list as follows
and click on OK then configuration will be saved. Make sure each argument separated
by SPACE.
Example
-Djavax.xml.bind.JAXBContextFactory=com.sun.xml.bind.v2.ContextFactory
|
Restart server then new configuration applies to the
server.
