I\'m manually running tomcat 6 as a windows service on the console. I need to change java_opts before starting it. How do I do that? Also, Is there a way I can see the logs dyna
You can set your JAVA_OPTS environment variable either manually via the command line prior to starting Tomcat:
set JAVA_OPTS=youropts
or you can edit catalina.bat
with the values you want.
In windows, cut the quotes on the set command. Quotes are taken literally.
To change the settings, create a file named setenv.bat for windows or setenv.sh for Linux with entry as below:
Windows:
set JAVA_OPTS="-Xms256m -Xmx512m"
Linux:
export JAVA_OPTS="-Xms256m -Xmx512m"
Simply put this(setenv.bat/setenv.sh) file in %CATALINA_HOME%\bin\ folder. Your command file (catalina.bat/catalina.sh) already has a statement as below:
Windows:
if exist "%CATALINA_HOME%\bin\setenv.bat" call "%CATALINA_HOME%\bin\setenv.bat"
Linux:
if [ -r "$CATALINA_BASE/bin/setenv.sh" ]; then
. "$CATALINA_BASE/bin/setenv.sh"
elif [ -r "$CATALINA_HOME/bin/setenv.sh" ]; then . "$CATALINA_HOME/bin/setenv.sh" fi This will take care the rest.
I know this is an old thread but needed to correct some assumptions.
Just an FYI, Catalina.bat is not utilized when running tomcat as a service. here is the method to change the JAVA_OPTS for tomcat running as a windows service.
Run the command
tomcat6w //ES//Tomcat6 (substitute your service name if different)
Click on the Java tab
Add the options (each on a new line) to the Java Options box and set the initial and max memory to 1536 and 2048
-XX:MaxPermSize=256m -Djava.awt.headless=true -Djava.net.preferIPv4Stack=true
Click apply
To alter the $JAVA_OPTS
, you will probably need to edit the batch file you use to start Tomcat. I don't run Tomcat on Windows, but the $JAVA_OPTS
appears in my catalina.sh
inside the bin/
directory on my Linux installation.
As far as viewing logs dynamically on Windows, there are a couple of options I'm aware of.
tail -f logfilename
like you would in Linux.
