Chapter 4 Uninstalling the Web Server

This chapter describes how to uninstall the Web Server software, and contains the following sections:

• Selecting the Uninstallation Mode

• Uninstalling in Graphical Mode

• Uninstalling in Command-Line Mode

• Uninstalling in Silent Mode

• Viewing Uninstallation Log Files

Selecting the Uninstallation Mode

There are three uninstallation modes: graphical, command-line, and silent. Use the uninstall command to specify the uninstallation mode. The syntax is as follows:

./uninstall [--help] [--console] [--silent] [--javahome java_dir][--saveinstances]

If you run the uninstall command without options, the uninstallation programs runs in graphical mode.

The following table lists the uninstall command options.

Table 4–1 Options for the uninstall Command

Option	Description
./uninstall --help	Displays the options for the uninstall command.
./uninstall	Runs the uninstaller in graphical mode.
./uninstall --console	Runs the uninstaller in command-line mode.
./uninstall --silent	Runs the uninstaller in silent mode.
./uninstall --javahome java_dir	Defines the location of the JDK installation that should be used for the uninstaller JVM, in graphical mode.
./uninstall --console --javahome java_dir	Defines the location of the JDK installation that should be used for the uninstaller JVM, in command-line mode.
./uninstall --saveinstances	Captures configuration information for a server instance before it is uninstalled, in command-line mode. All configuration information is removed during the uninstall process in silent mode. In all other modes, you are prompted during the uninstall process.

Uninstalling in Graphical Mode

The graphical interface is an interactive graphical wizard that walks through the uninstallation process. This is the default mode when the uninstallation program is started without options (./uninstall).

General navigation is as follows:

• Click Back to return to the previous screen.

• Click Next to move to the next screen.

• Click Cancel to cancel the installation.

• Click Help to display documentation specific to the current screen.

Note –

On UNIX systems, the uninstallation interface defaults to command-line mode if the DISPLAY environment variable has not been exported to your local machine and if X Windows is not supported. To uninstall in command-line mode, follow the instructions in Uninstalling in Command-Line Mode.

To Uninstall in Graphical Mode

1. Navigate to the install-dir/bin directory.

2. Start the uninstallation program

   • (UNIX) Type ./uninstall.

   • (Windows) Double-click uninstall.exe or type uninstall from the command line. You can also use the Control Panel > Add or Remove Programs option, or use Start > Programs > Oracle > Web Server 7.0 > Uninstall.

4. Click Next, and then Uninstall Now to proceed with the uninstallation.

   A progress bar shows status. Following uninstallation, a summary page displays. Click Details for more information, or Close to exit the uninstallation wizard.

Uninstalling in Command-Line Mode

To Uninstall in Command-Line Mode

1. Navigate to the install-dir/bin directory.

2. Start the uninstallation program with the following command:

   • (UNIX) ./uninstall --console

   • (Windows) uninstall --console

   The command-line uninstall interface displays.

3. Select Uninstall Now to proceed with the installation.

Uninstalling in Silent Mode

• From the command line, navigate to the bin directory in the Web Server installation directory, install-dir, and start the uninstallation program with the following command:

  • (UNIX)./uninstall --silent

Viewing Uninstallation Log Files

Log files are created during the uninstallation process. All uninstallation steps are logged, providing valuable troubleshooting information.

Uninstall Log

The uninstall log file is located as follows: install-dir/setup/Oracle_iPlanet_Web_Server_uninstall.log.

Uninstall log file entries contain information about the attempted action, the outcome of the action, and the cause of failure if applicable. Entries fall into three categories: INFO, WARNING, and ERROR. The following table describes each category.
