Installation and Upgrade


  1. Edit the configuration file.
    • On Ubuntu, the configuration file is <TomcatPath>/bin/
    • On CentOS/RHEL, the configuration file is /etc/tomcat/tomcat.conf.
    • On other Linux distributions, the configuration file is /usr/share/tomcat/conf.
  2. Add the following line:
    set JAVA_OPTS=%JAVA_OPTS% -XX:MaxMetaspaceSize=512m -Xmx1024m -Xms256m
  3. 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.
