Chapter 6 Uninstalling Policy Agent 2.2 for SAP Portal 6.0/Server 6.40

The agentadmin program is used for initiating the installation and uninstallation programs of Policy Agent 2.2 for SAP Portal 6.0/Server 6.40. The difference is that the installation program is started with the --install option while the uninstallation program is started with the --uninstall option. For more information about the agentadmin program, see Key Features and Tasks Performed With the J2EE agentadmin Program. The uninstallation program is similar to the installation program in that it provides step by step explanations of the information you need to enter. However, the uninstallation program has fewer and simpler steps.

The uninstallation process follows a series of tasks similar to the installation process. First, perform the pre-uninstallation (preparation) steps. Then, perform the uninstallation, itself. Finally, remove the agent files unless you want to configure a new agent using the same files.

Removing the agent files varies depending upon the format of the deliverable files used during the initial installation of the agent. Package formatted deliverable files are removed differently than files that are not package formatted.

You must access the PolicyAgent-base directory for uninstallation-related tasks. For more information about this directory, see J2EE Agent Directory Structure in Policy Agent 2.2.

This method of uninstalling Agent for SAP Portal 6.0/Server 6.40 applies to all the supported platforms.

This uninstallation process involves two phases as described in the following subsections.

Launching the Uninstallation Program of Agent for SAP Portal 6.0/Server 6.40

Perform the steps outlined in this section to launch the uninstallation program of Policy Agent 2.2 for SAP Portal 6.0/Server 6.40.

To Launch the Uninstallation Program of Agent for SAP Portal 6.0/Server 6.40

To launch the uninstallation program, perform the following steps:

1. Change to the following directory:

   PolicyAgent-base/bin

   These two commands are different in that the --uninstallAll option removes all configured instances of the agent.

   After you issue one of the preceding commands, the uninstallation program launches and presents you with the first prompt as illustrated in the following section.

Using the Uninstallation Program of Agent for SAP Portal 6.0/Server 6.40

The steps in the uninstallation program are displayed in the following example. The interaction process of this uninstallation program is similar to that of the installation program.

Removing the agent files is a simple process. However, the process is different depending upon how the agent deliverables were originally installed.

Two task descriptions follow. In most cases the first task description applies. Perform the appropriate task.

To Remove Files of Agent for SAP Portal 6.0/Server 6.40 on All Systems — Non-Packages

Perform the steps in this task description if the following conditions applied when the agent was originally installed:

• On any supported platform.

• Without package formatted deliverables.

1. Delete the PolicyAgent-base directory from the file system.

To Remove Files of Agent for SAP Portal 6.0/Server 6.40 on Solaris Systems — Packages

Perform the steps in this task description if both of the following conditions applied when the agent was originally installed:

• On a supported Solaris platform.

• With package formatted deliverables.

1. Issue the following command:
