Rem CATALINA_OPTS (Optional) Java runtime options used when the "start", If you open the catalina.bat or catalina.sh file, you will see this approach is recommended by Tomcat itself: JAVA_OPTS is also used to start JVMs that only interact with Tomcat (for example the JVM instance that is used to send the shutdown message to a running Tomcat instance). ![]() The former is only used when actually starting the Tomcat instance. Note that CATALINA_OPTS is a better place than JAVA_OPTS for putting JVM heap memory settings. On Linux, you can also set in the startup.sh file which is also available in the same bin folder. Xms – is the minimum or initial size of your heap Steps to increase heap size in Tomcat on Linux:Įxport CATALINA_OPTS=-Xms1023m -Xmx2048m The above command will increase the heap size of the tomcat to 2GB for both startup and maximum memory. Steps to increase heap size in Tomcat on Windows: Setting it in catalina.sh would apply to the process started by shutdown command as well, which may not be necessary. Don't worry that it will not override any previous JVM options, all the places a new value is set they ensure that it is appending to the existing values.ītw, I prefer setting it in the startup.sh instead of catalina.sh. When you increase heap memory by setting the JAVA_OPTS option as shown below. You should only extract this bin/tcnative-1.dll and nothing else, otherwise you will corrupt Crowd binary files.If you open the catalina.bat property you will see the advice given by the Tomcat creator itself on how to give additional JVM options to the Tomcat process. ![]() It contains the 圆4-compiled version of the same library.
