I dont believe you can force JAVA VM to run in 'server-mode' configuration
on any windows box
perhaps if you try to use -server option configured in the %JAVA_OPTS%
with a AMD64 bit processor?

C:\Programme\Java\jdk1.6.0_04\bin>java -version
java version "1.6.0_04"

Server class detection only describes the rules for automatic
client/server choice. You can always force your choice.
David: if you don't specify via -server/-client, it will be client VM on
32 Bit Win.

Subject: Tomcat 4.x, 5.x Client mode vs Server mode and JAVA_OPTS,
how-to-know which is running?
Hello TC committers, contributors and users. I am a long time TC user
and
it is the reason I have my current gig. In spite of the length of time
using
Tomcat I was not aware of the Client vs Server mode using the JAVA_OPTS
variable in catalina or the startup script. Currently, I am using JMeter
to
assess the webapps running under TC. I suspect a lot of my clients
problems
reside with the deployed webapps and not-so-such problems with TC. This
being said I would like to investigate performance issues with TC i.e. the
so-called Client vs Server mode. Is there some definitive test to know
which
mode a currently running TC instance is running under? There are 3
instances
I have to deal with: development deployment, test deployment and
production
deployment. Obviously, I cannot do anything to the Production app server
that would risk bouncing or shutting down the box. JMeter monitoring does
not work under TC 4.x because there is no manager/status page from which
to
parse the XML
data. The currently running TC instances are deployed as Services under
Windoe 2003 servers. I examied the properties dialog boxes from the
Services
application and I do not see any reference to JAVA_OPTS or any type of
startup params. If anyone has TC Client vs Server mode expertise or if you
just want to rant and rave please reply. The particulars follow. Thanks,
David.
OS: Windows 2003 server SP1
TC: 4.x and 5.x
JDK: 1.3.x and 1.4.x
Deployed as a service in all instances.
