Set Tomcat Startup Memory Size

To configure the memory size of Tomcat, you can either modify the startup script or add parameters to the startup command of Tomcat. Here is a common method.

1. Open the startup script for Tomcat, which is usually catalina.sh or catalina.bat.
2. If you cannot find the configuration item JAVA_OPTS in the script, it can usually be located at the beginning or end of the script. If not found, you can manually add the following configuration.

export JAVA_OPTS="-Xms512m -Xmx1024m"

Alternatively

set JAVA_OPTS="-Xms512m -Xmx1024m"

In it, -Xms indicates the initial heap memory size, and -Xmx indicates the maximum heap memory size. In the example above, the initial heap memory is set to 512MB and the maximum heap memory is set to 1024MB.

1. Save and close the startup script, then restart the Tomcat service for the memory size settings to take effect.

Please note that you can adjust the memory size settings as needed based on actual circumstances and application requirements.
