No, they're in the registry. Use the tomcat5w.exe program in the bin

Hi,
I notice an auto increase (no webapp running) of memory heap with

Any idea ?
It's almost impossible to have absolutely nothing running. If you have

that watch files to detect changes). However, you still

Howdy,
Is there a rule-of-thumb for setting the heap size based on how many
concurrent Tomcat processors/threads? Mine are mostly basic jsps and
servlets generating HTML. As I'll be running several Tomcat instances
for different apps, I need to allocate my 512M RAM to each Tomcat.

Shapira,
Howdy,
Yoav - Where do you specify heap size? I understand it is a parameter
of
the java command, but is in a Tomcat startup script somewhere? Or do I
just
execute it at the command line?
Add
JAVA_OPTS='-Xmx512m'
to
$CATALINA_HOME/bin/catalina.sh
on unix. On windows, you can do this with a

Thanks!

Subject: Re: heap size config
i deleted the message, but somebody was asking about how to specify heap
size in the params to tomcat, and i said you could probably pass such as a
param to startup.bat/startup.sh - not true. command line arguments are
passed through to the actual tomcat invocation, but *after* the classname,
my understanding is that any parameters you pass to bin/startup.bat or
bin/startup.sh on the command line will be passed through to the java vm,
such as mx128m or -D property=something .
The official way to do it is to set a
TOMCAT_OPTS
or
CATALINA_OPTS
variable with the string that you would normally feed the VM. (like -Xms or
whatever). TOMCAT is for 3.x, CATALINA is for 4.x
