I have one instance of Tomcat running for a single app. Is is possible
to create additional instances of tomcat, then cluster or load balance
the instances, to help my user performance?
That's going to depend entirely on the app, and what your limiting
factor is right now. If you just want to support more simultaneous
users, then probably yes. If your app doesn't perform well for even a
single user due to memory restrictions, then probably not.

The most a 32-bit OS can give to any process is ~3GB, and anything over
2GB requires changing some boot settings. But you'll be able to run a
bunch of tomcat instances, all with 2 or 3GB, with that much physical
RAM.

Windows Server 2003<- is this a 32 bit OS?
And if not, are you using 64 bit java vm?

Hi,
Apache Tomcat 6.0.20
Windows Server 2003
50G RAM
I'm running Apache Tomcat 6.0 as a service on a Windows 2003 Server
with 50G of RAM. I want to fully utilize the 50G of RAM (40G) but I
cannot get the Apache Service to start again if I go any higher than
the setting listed below:
-Xms1024m -Xmx1024m
-XX:MaxPermSize=256M
-XX:PermSize=512
I initially used the Tomcat Configuration Manager to attempt to
adjust
these setting. I also tried setting them in the registry,
HKLM/software/ApacheSoftwareFoundation/Procrun2.0/Tomcat6/Parameters/
J av e (jvms and jvmx). I also tried adding creating an Environmental
Variable; JAVA_OPTS -Xms1024m -Xmx1024m.
Thanks,
Rob
