Re: Tomcat and -server option
You are running Mac OS X. Does Apple support the Server Hotspot version? Maybe it falls back to client by default. Ronald.

Re: Tomcat and -server option
My observations have been similar as well. We discussed this on the Java Apple list as well and it seems that different vendors implement this differently.

RE: Tomcat and -server option
From: Mufaddal Khumri [mailto:[EMAIL PROTECTED] Subject: Re: Tomcat and -server option Does java.vm.name display the mode the JVM is executing in or its name of the JVM installed on my machine? It's the mode you're executing in. I don't have a UNIX/Linux system handy, but on a Windows machine, the client and server JVMs are packaged as separate DLLs. The launcher chooses which one to use based on a registry setting, if not overridden on the command line. (I presume something similar happens with UNIX.) The DLLs are stored in separate directories under your_jre/bin. The value stored in java.vm.name is hard-coded at compilation time of the JVM for each of the DLLs, so if it says client, that's what you've got. Why is the -server option not taking effect? A very good question. Check that you actually have both client and server directories under your jre/bin directory (not jdk/bin - check the jre inside the jdk). The 1.4.2 JRE for Windows does not include a server mode, whereas the JDK does, as does the 1.5 JDK. Don't know about the UNIX flavors, or the 1.5 JRE. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Tomcat 5 -server option and log files
Hello, I am trying to get Tomcat 5 to work with the server jvm, but I am having some problems. First I tried adding -server to the java options in the configure Tomcat program. When I did that Tomcat wouldn't start. Then I set C:\j2sdk1.4.2_02\jre\bin\server\jvm.dll - This worked and using stress test tool I found a significant boost in my web application - However, once I set the JVM to this path I no longer get any output to the log files of Tomcat. Neither from Tomcat itself or from my own logging commands. So, my question is two fold: 1) What is the correct way to set the JVM to use Sun's server JVM? 2) How do I get log output after I do that?

Re: Tomcat 5 -server option and log files
It looks like you should be able to add '-server' to the JavaOptions, but I haven't tried it. You could also do: tomcat //US//Tomcat5 --Java java --Arguments java -server As for the log redirection not working except for --Java=java, that's a known issue. I still haven't found something I'm completely happy with (mostly because of the messy way that MS handles output redirection).
