I'd recommend not setting these unless you really know what's going on inside your heap. It's usually more beneficial to set -Xms to the same value as -Xmx. > > Also, is there a way to start tomcat and have it > > spit out what JAVA_OPTS it's using? Some of the options are processed by the launcher, some by the JVM proper, so there's not any really good way to see them all. You can set the environment variable _JAVA_LAUNCHER_DEBUG, and it will provide some information about what the launcher is doing and what it's passing on to the JVM. Lambda Probe will let you look at System properties, some of which are derived from the command line arguments. (You can also find them in JConsole, but it's ugly.) JConsole will also show the arguments the JVM sees under java.lang -> Runtime -> Attributes -> Input Arguments on the MBeans tab. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
