If you run “ps” and “grep” for something like “java”, “catalina”, etc.. you can find your running Tomcat process. On Linux this should show the full command that was run. Alternatively, you could use “jinfo <pid>”. That will dump a bunch of info including the VM Flags. > > I have tried creating setenv.sh and putting the new parameters in it. but > echo $JAVA_OPTS was not giving any value. How did you install Tomcat? Did you use your distro’s package manager? Did you download from tomcat.apache.org? How are you starting your server? Are you using the included start script? Are you using an init.d (or other) script you created? Are you using commons daemon? > So I have put in .bash_profile and run it. Don’t do that.

If you downloaded from tomcat.apache.org and installed from the zip, you’d put them in bin/setenv.sh and it would work. If you’re using a packaged version of Tomcat from your Linux distro, then it may well be different. If you gave more details, perhaps someone on the list could help.
