How to recover from a crashed Java / Tomcat

Hi,

We run a bunch of Java / JSP based programs via Tomcat Jakarata.

What should one do to totally re-start the related Tomcat Jakarata when
it crashes and as the result no JSP based pages load?

Regards,

Issue shutdown and startup commands.
Tomcat User’s Guide

I already looked at this page.
But it is not helping.

FYI, we are running RedHat Enterprise.
