Can anyone please educate me on the below issue :
I run my application application on tomcat 5.5 with jre 1.5. It runs on a Redhat linux server machine. I use eclipse 3.3 to develop the application. Recently, there has been a requirement to make changes on the Xms and XmX parameters as we have been developing some file reading functionalities and we've been having some errors about memory issues. The problem got solved after getting done the above task on my developer client machine. The changes are to be made on the Server machine too.
On the server machine, I deploy the application by putting the WAR file in the Webapps folder. I have never tried the Xms, XmX configuration on linux. (As a matter of fact, I have done it on my client developer machine).
What I would like to know is, if i make changes on the Tomcat to alter the above parameters, will it in any way effect other applications using the system's JRE but, running on other web servers?
I believe the changes are supposed to be made to the catalina.sh or some other file in Tomcat_home and not to any other installed java files.
Can anyone please share more knowledge on all of the above matters?

The answer is "it depends". Google for something like "JVM tuning" for you particular JVM.
