Installing the Configuration Servlet

During the Host On-Demand installation, the user choose to have the configuration servlet installed and configured on i/OS, OS/400, Windows, AIX, Linux, and Solaris for HOD Application Server.

All Web servers and servlet engines are configured differently. Check the Web server and servlet engine documentation for servlet configuration details on the operating system.

Installing the configuration servlet is necessary only if both of the following statements are true for the Host On-Demand deployment:

The user plan to configure Host On-Demand so that client communication with the Service Manager is necessary (as in the configuration server-based and combined deployment models, if the user enable License-Use Counting, or if the user use the Redirector).
A firewall protects the server(s) on which the user plan to maintain session configuration information, and the user do not want to open a port in that firewall to give outside clients access to the Service Manager.

By default, the Host On-Demand clients use port 8999 to access configuration information from the Service Manager. If any of the user clients are outside the firewall, the firewall administrator needs to open port 8999 both internally and externally. However, the user avoid opening this port by customizing your clients to use the configuration servlet to access configuration information.
