Do we need to set CATALINA_HOME AND CATAlINA_BASE explicitly ?

[naveen yadav]

hi ranchers,

after installing Tomcat , do CATALINA_HOME AND CATAlINA_BASE has to be set explicitly as environment variable?

In tomcat properties under java options these variables has been set by default.

-Dcatalina.home=C:\Program Files (x86)\Apache Software Foundation\Tomcat 6.0
-Dcatalina.base=C:\Program Files (x86)\Apache Software Foundation\Tomcat 6.0
-Djava.endorsed.dirs=C:\Program Files (x86)\Apache Software Foundation\Tomcat 6.0\endorsed
-Djava.io.tmpdir=C:\Program Files (x86)\Apache Software Foundation\Tomcat 6.0\temp
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=C:\Program Files (x86)\Apache Software Foundation\Tomcat 6.0\conf\logging.properties



Do have to set them explicitly ?



One more thing if i had to reset the catalina.base or set more than one catalina.base. can it done be here ?

I'm remembering that Tomcat has a setEnv.sh or setEnv.bat .. which set up the environment variables according the installation path. Please take a look into those files ...

No. Tomcat will set those. All you need to set is JAVA_HOME.

[Tim Holloway]

when you launch Tomcat using one of the scripts that starts the server, such as catalina.sh, the script will default CATALINA_HOME and CATALINA_BASE to point to the parent of the directory containing the script. You do need JAVA_HOME, though - it must point to a JDK for Tomcat6 or lower. I can't remember if they managed to finally remove this restriction in Tomcat 7.

The only times you HAVE to set CATALINA_HOME and/or CATALINA_BASE are if you want to override the default values. Most commonly, you'd do that if you were using the same Tomcat binaries to run multiple instances of Tomcat.
