Tomcat

In Tomcat 5.5, the manager GUI comes packaged, but not configured. To configure:

cp tomcat5.5/server/webapps/manager/manager.xml tomcat5.5/conf/Catalina/localhost/

vi tomcat5.5/conf/tomcat-users.xml

add:

<role rolename="manager"/>
<user username="admin" password="test1234" roles="tomcat,manager"/>

restart Tomcat.

The manager GUI can now be seen at:

http://hostname:8080/manager/html

and you will be prompted for the username and password you provided in the tomcat-users.xml

To improve performance (most of the time) for Tomcat (and most any other java application server), the server can be run with the Java option "-server", which optimizes performance at startup, and can increase start up time quite a bit in some instances, but typically increases performance under normal use.

This can be set anywhere that you set JVM options, but for Tomcat, I set these options in the tomcat user (tcsh) profile as such:

setenv CATALINA_OPTS "-server -Xms128m -Xmx128m -XX:NewSize=48m -verbose:gc"
