Installation

Extract the contents of the Germain Server distribution to a temporary folder, then move the tomcat8 directory to a location of your choice. Set the CATALINA_HOME environment variable to the Tomcat directory.

Windows Service

To install Tomcat as a Windows service, navigate to the Tomcat directory and execute the following commands:

cd %CATALINA_HOME%
.\bin\service.bat install GermainAPMServer
JAVA

It will create a Windows Service with a name like "Apache Tomcat #.# GermainAPMServer".


You can adjust the Java runtime properties for the service by using the following command:

cd %CATALINA_HOME%
.\bin\tomcat8w.exe //ES//GermainAPMServer
JAVA 
For example, to have the server crash in case of running out of memory, add the following parameter:
cd %CATALINA_HOME%
-XX:+CrashOnOutOfMemoryError
JAVA
