Chapter 6 Uninstalling Policy Agent 2.2 for Oracle Application Server 10g
The agentadmin program is used for initiating the installation and uninstallation programs of Policy Agent 2.2 for Oracle Application Server 10g. 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.
The uninstallation process differs depending upon the format of the deliverable files used during the initial installation of the agent: package formatted deliverable files or non-package formatted deliverable files.
If package formatted deliverables were used for installation of the agent, the uninstallation involves a single step.
If non-package formatted deliverables were used for installation, uninstallation consists of two phases. The first phase of uninstallation is the launching of the uninstallation program. The second phase of uninstallation involves interacting with the uninstallation program. During this phase, the program prompts you step by step to enter specific information while providing you with explanations about that information.
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.

Solaris Systems — Packages: Uninstalling Agent for Oracle Application Server 10g
This method of uninstalling Agent for Oracle Application Server 10g does not apply to all Solaris system uninstallations. This method only applies when the agent was originally installed using package formatted deliverables. Such deliverables are installed by issuing the following command:
# pkgadd -d
Package formatted deliverables have the string “_SUNWam” in the name of the compressed file used for delivering the Policy Agent 2.2 software. The following file name is an example of package formatted deliverable file used for Policy Agent 2.2 for Oracle Application Server 10g:
SJS_Oracle_1012_agent_2.2_SUNWamoc4j.tar.gz
For more information about package formatted deliverables for Solaris systems, see To Unpack Package Formatted Deliverables of a J2EE Agent in Policy Agent 2.2.
To uninstall this agent when the original deliverables were not in package format, regardless of the platform, see Launching the Uninstallation Program of Agent for Oracle Application Server 10g.
To Uninstall Agent for Oracle Application Server 10g on Solaris
Systems — Packages

# pkgrm SUNWamoc4j
The preceding command removes the J2EE agent packages from the directory in which they were installed.
All Systems — Non-Packages: Uninstalling Agent for Oracle Application Server 10g
This method for uninstalling Agent for Oracle Application Server 10g applies when the agent was originally installed using non-package formatted deliverables. The term “non-package formatted deliverables” refers to the format of the compressed file used for delivering the Policy Agent 2.2 software. Package formatted deliverables have the string “_SUNWam” in the name of the compressed file. Therefore, non-package formatted deliverables do not have this string in the file name. The following two file names are examples of non-package formatted deliverable files used for Policy Agent 2.2 for Oracle Application Server 10g:
SJS_Oracle_1012_agent_2.2.tar.gz SJS_Oracle_1012_agent_2.2.zip
This uninstallation process involves two phases as described in the following subsections.
