The servlet.config File
You may need to change the following entries:
Environment Variables
The SERVLET_JSP_HOME environment variable must be set, as follows:
Set env(SERVLET_JSP_HOME) /usr/tandem/webserver/servlet_jsp
Filemaps
For each new application (a collection of related servlets, JSP and other resources) you
must add a corresponding filemap in the servlet.config file.
For example, assume you have a new application called orders, you will have to add the
following filemap.
Filemap /orders $server_objectcode
Server Directive
•
Among many other entries, Numstatic and Maxservers are set in the server
directive. The default situation is that both are set to 1, because the NonStop Servlets
for JavaServer Pages process is multithreaded.
To support sessions, all processes in the web container must be static. That is, the
Numstatic and Maxservers attributes of the web container must have the same value.
If the values are not equal, the LINKMON will bring up additional dynamic Servlet
server processes based on the system load. If a dynamic Servlet server process is
shut down because the system load has decreased, all the session data it contained
will be lost.
The following entries must not be changed:
•
Arglist parameter. The arglist parameter in the server directive has been used to
specify the following configuration:
The class file which the servlet server process loads immediately upon startup.
org.apache.tomcat.startup.Tomcat
The NonStop Servlets for JavaServer Pages home directory
-Dtomcat.home=$env(SERVLET_JSP_HOME)
The name of the customized server.xml file for NonStop Servlets for JavaServer
Pages to use
-f conf/iTP_server.xml
