CPU Binding - How to enable sun 1.3.1 for multi cpu

I am using the following JAVA version

java version "1.3.1_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3. Java 
HotSpot(TM) Client VM (build 1.3.1_03-b03, mixed mode)

I have noticed that only 1 CPU on a 4 CPU machine is handling load for
JAVA, can anyone help in how to configure JAVA to span the total number
of processors ?

Regards,
John

Good day,
 
Does anyone know how one sets Tomcat 4.0.6 to utilise more than one CPU
in a multiple CPU machine.
 
Tomcat is running on Windows Server 2003 on a 4CPU IBM machine, and all
the utilisation graphs indicate that the tomcat service is only using
one CPU, I have trawled the documentation and cant seem to spot the
config details to do this ?
 
Regards,
John

Posted by Antonio Fiol Bonnín <fi...@terra.es>.
On Linux, you can choose "green threads" or "native threads". The former 
means single process, so one CPU, and the latter means multiple 
processes, so it benefits from multiple CPUs.

No idea under Windows.

Good luck.
