Subject RE: Tomcat Out of memory
Date Thu, 23 Jan 2003 09:37:22 GMT
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"
-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 -? 

Hope that helps.
