You should check to see what the difference is for your shell. catalina.sh just calls /bin/sh which could be anything, depending on your system. I'm pretty sure that all shells will make the mentioned variable available to sun-processes of the current process. catalina.sh IIRC only uses those variables on the command lines of processes it invokes, and therefore there is no difference whether you export or not. > 2.

Read the top of catalina.sh: # JAVA_OPTS (Optional) Java runtime options used when the "start", # "stop", or "run" command is executed. versus: # CATALINA_OPTS (Optional) Java runtime options used when the "start", # or "run" command is executed. There's probably no need to have Tomcat start-up a 1GiB JVM just to send a "shutdown" command, for instance ;) > All we care about is memory utilization and allocation, not > environmental variables per se. Thanks! Then my example above is a good one. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkqYKdQACgkQ9CaO5/Lv0PC9uwCfewlhtvPFrXjK4L/pbWR4dyEu v8YAn3vNEWzySX7nASrp/Vqg4ORzgo5/ =GxRi -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
