OutOfMemory on FreeBSD
Hello,
I'm trying to find how to send jvm parameters (-Xm128m) to the JVM during
tomcat startup. I have an application (openreports) that fails with
outofmemory exception intermittently.
I have seen some references here and there, but nothing that indicates which
tomcat (or java, [or freebsd]) configuration file that I need to touch.
Any pointers are appreciated.
thanks,
lane

You can set the environment variable JAVA_OPTS, e.g.
export JAVA_OPTS='-Xm128m'
Note that this would require writing a wrapper script to call the Tomcat
scripts, since it'd be silly to do this by hand all the time.
The extra script may sound like a pain, but it actually makes your setup
less sensitive to Tomcat upgrades because you won't have to modify
anything in the Tomcat tree.

Hey, I guess I can answer my own question! Don't you just love it when that
happens!
The makefile for tomcat5 on FreeBSD doesn't give the option to add additional
parameters. There is probably a better way to do this than to hard-code more
variables, but I'm not sure how to do it. So for anyone else who runs into
OutOfMemory exceptions on FreeBSD or the dreaded "Can't connect to X DISPLAY"
error, make these changes to /usr/ports/www/jakarta-tomcat5/Makefile:
In the do-install target:
change:
-e "/%%JAVA_ARGS%%/s//\"-Dcatalina.home=${APP_HOME:S/\//\\\//g}\",/g" \
to:
-e "/%%JAVA_ARGS%%/s//\"-Djava.awt.headless=true\",\"-Xms128m\",\"-Xmx256m\",
\"-Dcatalina.home=${APP_HOME:S/\//\\\//g}\",/g" \
then do:
make -DFORCE_PKG_REGISTER do-install
This will overwrite the current tomcat50ctl but will preserve your existing
tomcat installation.

liukang@bjpu.edu.cn and liukang@bjut.edu.cn appear
in /usr/ports/www/jakarta-tomcat5/Makefile
