Tomcat Setting

1- Configured maximum Size for war apps

Solution

Go to the web.xml of the manager application (for instance it could be under /tomcat7/webapps/manager/WEB-INF/web.xml.

Increase the max-file-size and max-request-size:

<multipart-config>

<!– 50MB max –>

<max-file-size>52428800</max-file-size>

<max-request-size>52428800</max-request-size>

<file-size-threshold>0</file-size-threshold>

</multipart-config>

2- OutOfMemoryError: PermGen space

It’s usually happened when the Tomcat start and stop few times. It’s just funny, however you can fine tune it with some minor changes in the Tomcat configuration setting. By default, Tomcat assigned very little memory for the running process, you should increase the memory by make change in the startup.bat and catalina.bat or startup.sh and catalina.sh files in your tomcat/bin directory.

Solution (Windows)

1) Find where is cataline.bat located. We need to make some changes in “catalina.bat” file.

2) Assign following line to JAVA_OPTS variable and add it into catalina.bat file.

set JAVA_OPTS="-Xms1024m -Xmx10246m -XX:NewSize=256m -XX:MaxNewSize=356m -XX:PermSize=256m -XX:MaxPermSize=356m" 3) If not work set set CATALINA_OPTS=-Xms512m -Xmx512m -XX:MaxPermSize=256m

Or ( for 2 and 3) add at the end of the text box “Java Options” of “configure” tomcat 7 -Xms512M -Xmx512M -Xss1024K -XX:MaxPermSize=512M -XX:PermSize=512M

4) Done. Restart Tomcat.

You should change the “Xms” and “PermSize” value base on your server capability.
