Hi,
I'm getting out of memory exception errors.
Exception in thread "Timer-1" java.lang.OutOfMemoryError: Java heap space

Is there anyway to see currently set jvm heap size details? Any linux
commands.
I have tried creating setenv.sh and putting the new parameters in it. but
echo $JAVA_OPTS was not giving any value. So I have put in .bash_profile
and run it. Then restarted tomcat6.
this is the line I added in .bash_profile.
JAVA_OPTS="-Xms256m -Xmx512m -Xss512k -verbose:gc -Xloggc:heap.log"
Also I checked in heap.log where catelina.out can be found. But its not
created. Then I touched and restarted. But that also didn't work.
What is the right way to do this?
