Increasing the memory of Tomcat

Last updated: 8/28/2025

Procedure

Edit the configuration file.
- On Ubuntu, the configuration file is <TomcatPath>/bin/catalina.sh.
- On CentOS/RHEL, the configuration file is /etc/tomcat/tomcat.conf.
- On other Linux distributions, the configuration file is /usr/share/tomcat/conf.
Add the following line:
set JAVA_OPTS=%JAVA_OPTS% -XX:MaxMetaspaceSize=512m -Xmx1024m -Xms256m
If you are an Oracle user, add the following line in order to specify the catalog and schema database parameters, and to avoid errors during Talend Administration Center startup:
Xmx<1G> -Dtalend.catalog=<catalogName> -Dtalend.schema=<schemaName>

The Tomcat memory size is now increased and the server can hold several web applications.
