Another option which uses fewer resources but doesn't provide quite the same degree of isolation is to run two hosts in the same Catalina service. If your DNS maps www.mydomain.com and test.mydomain.com to the same IP address, they can share the same ports. Each one can have its own logs, Servlet mappings, and set of apps.

Yes. I run up to four on this machine - two (one 4.1, one 5.0) are running as I type this. Here's a Windows script that works (give or take the HOME path) for Tomcat 4 and 5.0 - untested on 5.5, but I can't see why it should fail. The UNIX equivalent is pretty obvious. Check out CATALINA_HOME - where Tomcat is installed - versus CATALINA_BASE - where this instance stores its files. Note the JAVA_OPTS for increased stack and heap sizes, too; this line is optional. C:\cattery is where I store the data for the four instances. -- snip -- set CATALINA_HOME=C:\Program Files\Apache Group\Tomcat 4.1 set CATALINA_BASE=c:\cattery\instance1 set JAVA_OPTS=-Xms64m -Xmx256m cd %CATALINA_HOME%\bin startup -- snip -- Under CATALINA_BASE for each instance, you'll need conf, logs, temp, webapps, and work directories. The easiest way to create these is to copy them from CATALINA_HOME. You'll then need to modify conf/server.xml to make sure each instance is running on its own ports - don't forget to change the shutdown port! Good luck, yell if you have any problems getting this to work. - Peter --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
