Thanks for a quick reply.

Is it only the benifit , I mean I have pc anywhere or similar tools, or even
I dont need the smart load/unload as a service.
I want  to know the comparison based on
Memory usage, performance at runtime etc.

The benefits are that you can get it to start and stop with the machine and
a non tomcat admin can start and stop it using the services. It can also be
remotely started if you have the right tools. And it doesnt require a user
to be logged in for the service to remain running.

Can any one quickly tell the comparison of running tomcat as a service or
without a windows service.
I mean what are the benifits of running tomcat as a windows service.

no, the address already in use is tcpListenPort, that has to change if you
run two instances on the same machine

Hi again,

you are right with the 2Gb, sorry. It's leaving a netto of 1.6 GB ish for
Tomcat here.

My problem was referring to the clustersection of server.xml rather than the
standard IP:

 mcastAddr = the multicast address, has to be the same for all the nodes
 mcastPort = the multicast port, has to be the same for all the nodes

So even when everything else can be configured per Instance, these addr
needs to be the same. So when I start up the second instance of Tomcat on
the server, it says that the mcastAddr (="228.0.0.4" port 45564) is already
in use and it can't bind to it ...

Memory limit should be 2 Gig for JVM's running in a 32 bit operating system.
More for the 64 bit JVM's. I think you would have to have virtual IP
addresses on that machine and run tomcats on specific IP addresses for you
to use the multicasting.

Hi,

can anyone tell me how Tomcats can be configured as a cluster with session
replication when there is more than one TC-Instance on one machine?
We need multi-instance because of the 1 Gig mem-limit to the jvm's. Or has
that changed meanwhile too?
