Heap recommendations for Tomcat 7

[John Beaulaurier -X (jbeaulau - ADVANCED NETWORK INFORMATION INC at Cisco)]

Hello,

Is there a good formula for JDK Heap parameters for Tomcat 7 as it relates to 
hardware, or should ergonomics be allowed to define, or is it more application 
driven?


OS: RHEL 5.5

Kernel: 2.6.18-194.8.1.el5

Apache Tomcat: 7.0.39

JDK: 1.6.0_45



Thank you

-John
