Check this out, it is an earlier thread that was running on this list regarding my experience with the same problem. I've posted the entire thread below
OR If you want to make it easier on yourself, just paste the stuff below into a .bat file and execute it from the bin folder under tomcat, and it will re-install the service with the parameters specified. You will have to make sure that it has your correct directories (jdk, tomcat home, etc) and that the server memory params are what you want tomcat.exe -install "Apache_Tomcat" "C:\j2sdk1.4.1_02\jre\bin\client\jvm.dll" -server -Xmx1024m -Xms1024m -Djava .class.path="d:\Tomcat\bin\bootstrap.jar" -Dcatalina.home="d:\Tomcat" -Djava .endorsed.dirs="d:\Tomcat\common\endorsed" -start org.apache.catalina.startup.BootstrapService -params start -stop org.apache.catalina.startup.BootstrapService -params stop -out "d:\Tomcat\logs\stdout.log" -err "d:\Tomcat\logs\stderr.log" ----- Original Message ----- From: "Reynir H�bner" <[EMAIL PROTECTED]> To: "Tomcat Users List" <[EMAIL PROTECTED]> Sent: Thursday, January 23, 2003 3:37 AM Subject: RE: Tomcat Out of memory Nate, to increase the memory for your tomcat-running as service in NT / win2k/winXP you must re-install the service. You probably have noticed that the service does not start the catalina.bat file but the tomcat.exe. You can uninstall the current service and install again by using tomcat.exe Go to c:\jakarta-tomcat-4-1-18\bin\ and execute tomcat.exe to do so, you will need some parameters (all in the same line): tomcat.exe -install "Apache Tomcat 4.1" "C:\java1_4_1\jre\bin\client\jvm.dll" -Xmx512m -Djava.class.path="C:\jakarta -tomcat-4-1-18\bin\bootstrap.jar" -Dcatalina.home="C:\jakarta-tomcat-4-1-18" -Djava.endorsed.dirs="C:\jakarta-tomcat-4-1-18\common\endorsed" -start org.apache.catalina.startup.BootstrapService -params start -stop org.apache.catalina.startup.BootstrapService -params stop -out "C:\jakarta-tomcat-4-1-18\logs\stdout.log" -err "C:\jakarta-tomcat-4-1-18\logs\stderr.log" Then for instructions you can always run tomcat -?

My system (W2k IIS5.0 - JSDK 1.4.0). I'm expecting my site will have a heavy load (about 20,000 concurrent connections between several servers) My pages wont have database connections. I've read some documents about it, and I wonder if someone could tell me what's the limit of the parameters minProcessors, maxProcessors and acceptCount, when I configure minProcessors above 1000, Tomcat stops after about 30 seconds. �? Does it really improves performance? Another question: How can I increase the the memory configuration of JVM. I've read that is donde with the Xms, xms,ms and mx options, but how can I tell Tomcat to use that configuration. (i'm using Tomcat as a service) I've tried using it with no luck. Would that work if I edit cataliba.bat and add those options in %JAVA_OPTS%. Does anyone have some good tips about performance? (besides the documents found in the FAQ section) Regards.
