Multiple JVM in Tomat
Hi all,
Do you have any documentation link on how to setup
tomcat to spawn a different JVM per webapp ?
Cheers,
Jerome

The same impact as a single Tomcat starting multiple VMs (however /that/
would work).

Yes. More JVMs means more memory required.

Look at the RUNNING.txt file that comes with every Tomcat distribution.
If you have a package-managed bundle of Tomcat, just download one of the
"real" packages from the Tomcat web site and read that file. It should
still be accurate.

OK so I would have several tomcat instances running on
different ports. This is fine but how would that
impact memory usag eon the server ? I guess every
tomcat instance needs quiet a bit of initial memory.
Then that means this amount of memory would be
multiplied by the number of webapps...
Also, any link on that doc ? Can't find it in the main
Tomcat documentation...

"By hand". See the documentation on setting up multiple instances - to
my knowledge, there's no way of setting up Tomcat to spawn JVMs. Note
that each instance will require its own set of ports.
