I have installed Tomcat version 6 on a our zos2.2 system. It is up and running and working as expected. I have been asked to change the parameter called 'connectionTimeout' to 5hrs. Where would I add the parameter?

Thanks Matt

The Tomcat configuration on Unix/Window is in server.xml.
For the tz Tomcat distribution, these are in SERVXML and SERVVARS configuration members.
See: https://dovetail.com/docs/tomcat/config.html for details.
