- Windows running Tomcat 5.5 and later : Go to the "Apache Tomcat x.x"
folder in the Start Menu. Start the "Configure Tomcat".
Select the "Java" tab in the configuration dialog.
- *Server mode:* this is determined by the jvm.dll specified in the
"Java Virtual Machine" text box. (One should not specify the "-server" or
"-client" JVM option.)
The server .dll is usually placed under a "server" directory in the
JRE directory.
For example: "C:\Program
Files\Java\jdk1.5.0_07\jre\bin\server\jvm.dll".
The complete SDK should be downloaded for this from Sun, as the JRE
installers only contain the "client" directory.
- *Maximum heap size:*The "Maximum memory pool" text box coresponds to
the heap size limit.
(If using this text box it is not needed to specify "-Xmx" Java
option.)
- Advanced JRE options can be specified in the "Java Options" text
area. Append your other Java options at the bottom of the option list.
- Windows running Tomcat 4.1 or earlier : place the Java options into the
CATALINA_OPTS environment variable. To do this, run Control Panel / System,
select Environment Variables and create the CATALINA_OPTS variable, and set
the desired option, for example "-server -Xmx400m".
- Linux : place the Java options into the CATALINA_OPTS environment
variable. For example: "-server -Xmx400m".
