After you issue the agentadmin command and accept the license agreement (if necessary) the installation program appears, prompting you for information.
The steps in the installation program are displayed in this section in an example interaction. Your answers to prompts can differ slightly or greatly from this example depending upon your specific deployment. In the example, most of the defaults have been accepted. This example is provided for your reference and does not necessarily indicate the precise information you should enter.
The following bulleted list provides key points about the installation program.
Each step in the installation program includes an explanation that is followed by a more succinct prompt.
For most of the steps you can type any of the following characters to get the results described:
Type the question mark to display Help information for that specific step.
Type the left arrow symbol to go back to the previous interaction.
Type the exclamation point to exit the program.
Most of the steps provide a default value that can be accepted or replaced. If a default value is correct for your site, accept it. If it is not correct, enter the correct value.
The following list provides information about specific prompts in the installation. Often the prompt is self explanatory. However, at other times you might find the extra information presented here to be very helpful. This extra information is often not obvious. Study this section carefully before proceeding.
Enter a Universal Resource Identifier (URI) that will be used to access Agent for Sun Java System Web Server 7.0. The default value is /amagent.
The web agent uses the value of the com.sun.am.policy.agents.config.agenturi.prefix property in the web agent AMAgent.properties configuration file to support some essential functions such as notification and POST data preservation. Web agent URI prefix is a configurable subset of Web Agent Deployment URI. It is important to set a valid URL for this property. Its value should be http://agentHost1.domain:port/web-agent-deployment-uri where agentHost1, domain and port are FQDN and port number of the Sun Java System Web Server 7.0 instance where the agent is installed and web-agent-deployment-uri is the URI where the Sun Java System Web Server 7.0 instance will look for web-agent related HTML pages. Its default value is amagent.
The following is an example of an Agent Deployment URI:
http://agentHost1.example.com:80/amagent
An agent profile should have been created as a pre-installation step. The creation of the agent profile is mentioned in that section. For the pre-installation steps, see Preparing to Install Agent for Sun Java System Web Server 7.0. For the actual information on creating an agent profile, see Chapter 5, The Relationship Between the Agent Profile and Web Agents in Policy Agent 2.2.
In summary, the web agent communicates with Access Manager with a specific ID and password created through an agent profile using Access Manager Console. For web agents, the creation of an agent profile is not mandatory. However, Access Manager uses the agent profile to authenticate an agent. This is part of the security infrastructure.
The web agent profile password file should have been created as a pre-installation step. For the pre-installation steps, see Preparing to Install Agent for Sun Java System Web Server 7.0.
When the installation program prompts you for the password for the agent, enter the fully qualified path to this password file.
After you have completed all the steps, a summary of your responses appears followed by options that allow you to navigate through those responses to accept or reject them.
When the summary appears, note the agent instance name, such as Agent_001. You might be prompted for this name during the configuration process.
About the options, the default option is 1, Continue with Installation.
If you are satisfied with the summary, choose 1 (the default).
If you want to edit input from the last interaction, choose 2.
If you want to edit input starting at the beginning of the installation program, choose 3.
If you want to exit the installation program without installing, choose 4.
You can edit your responses as necessary, return to the options list, and choose option 1 to finally process your responses.
The following example is a sample installation snapshot of Policy Agent 2.2 for Sun Java System Web Server 7.0. By no means does this sample represent a real deployment scenario.
The section following the installation summary section, Implications of Specific Deployment Scenarios in Agent for Sun Java System Web Server 7.0, explains specific deployment scenarios, such as installing multiple agent instances. Review the information in that section before proceeding with the installation. That information is divided into subsections as follows:

At the end of the installation process, the installation program prints the status of the installation along with the installed web agent information. The information that the program displays can be very useful. The program also displays the location of specific files, which can be of great importance. In fact, you might want to view the installation log file once the installation is complete, before performing the post-installation steps as described in Chapter 6, Post-Installation of Policy Agent 2.2 for Sun Java System Web Server 7.0.
The location of directories displayed by the installer are specific. However, throughout this guide and specifically in Summary of Agent Installation shown in this section, PolicyAgent-base is used to describe the directory where the distribution files are stored for a specific web agent.
The following example serves as a quick description of the location of the web agent base directory (PolicyAgent-base) of Policy Agent 2.2 for Sun Java System Web Server 7.0.
The following directory represents PolicyAgent-base of Agent for Sun Java System Web Server 7.0:
Agent-HomeDirectory/web_agents/sjsws_agent |
where Agent-HomeDirectory is the directory you choose in which to unpack the web agent binaries.
Information regarding the location of the web agent base directory is also explained in Location of the Web Agent Base Directory in Policy Agent 2.2.
The following type of information is printed by the installer:
SUMMARY OF AGENT INSTALLATION ----------------------------- Agent instance name: Agent_001 Agent Configuration file location: PolicyAgent-base/Agent_001/config/AMAgent.properties Agent Audit directory location: PolicyAgent-base/Agent_001/logs/audit Agent Debug directory location: PolicyAgent-base/Agent_001/logs/debug Install log file location: PolicyAgent-base/logs/audit/install.log Thank you for using Access Manager Policy Agent |
Once the agent is installed, the directories shown in the preceding example are created in the Agent_00x directory, which for this example is specifically Agent_001. Those directories and files are briefly described in the following paragraphs.
Location of the web agent AMAgent.properties configuration file for the agent instance. Every instance of a web agent has a unique copy of this file. You can configure this file to meet your site's requirements. For more information, see the following sections:
Location of the web agent local audit trail.
Location of all debug files required to debug an agent installation or configuration issue.
Location of the file that has the agent install file location. If the installation failed for any reason, you can look at this file to diagnose the issue.
The following sections refer to specific deployment scenarios involving Policy Agent 2.2 for Sun Java System Web Server 7.0. These scenarios are likely to affect how you respond to prompts during the installation process. You might also need to perform additional configurations.
After you install the agent for a specific Sun Java System Web Server 7.0 instance, you can install the agent on another Web Server 7.0 instance by executing the agentadmin --install command again.
Installing Agent for Sun Java System Web Server 7.0 on the Access Manager Host is not recommended for production deployments in that performance is degraded.
To install this web agent on the Access Manager host, on the same Sun Java System Web Server 7.0 instance, add all of the URLs related to Access Manager to the not enforced URL list. Configuring the not-enforced URL list is described in Configuring the Not-Enforced URL List. If you are installing the agent on a different Sun Java System Web Server 7.0 instance, configuration of the not-enforced URL list is not required.
