Installation guide

Before You Begin Installation
18 Sun ONE Identity Server Policy Agents 2.1 • Web Policy Agents Guide • April 2005
Remote Web Servers
You can use the installation program to install a policy agent on the web server
where Sun ONE Identity Server is installed. In Sun ONE documentation, this
server is referred to as the web server that runs the Sun ONE Identity Server. You can
also use the installation program to install additional policy agents on remote web
servers in your enterprise. A remote web server in a Sun ONE Identity Server
deployment is any web server other than the one that runs Sun ONE Identity
Server. It is “remote” relative to the Sun ONE Identity Server’s dedicated web
server.
Configuring the Agent for Multiple Web Server
Instances on the Same Computer
If you have multiple web server or proxy server instances installed on one
computer system, you can configure the agent for each server instance.
For information on how to do this, see “Configuring the Agent for Multiple Web
Server Instances.”
Providing Failover Protection for Agents
When youinstall a policy agent, you can specify a failover orbackup web server for
running Sun ONE Identity Server. This is essentially a high availability option. It
ensures that if the web server that runs Sun ONE Identity Server service becomes
unavailable, the agent can still process access requests through the secondary or
the failover web server running Sun ONE Identity Server service.
To set up failover protection for the policy agent, you must first install two
different instances of Sun ONE Identity Server on two separate web servers. See
the detailed instructions in the Sun ONE Identity Server Installation and
Configuration Guide to do this and then follow the instructions in the subsequent
chapters of this guide to install the appropriate agent. The agent installation
program will prompt you for the host name and port number of the failover web
server that you have configured to work with Sun ONE Identity Server. The
following property inthe AMAgent.properties file stores thefailover server name
and port:
NOTE
Only one instance of Microsoft IIS server can be installed per computer system;
you cannot install multiple Microsoft IIS agents on the same computer system.
