6 Deinstalling Oracle WebCenter Portal

This chapter describes how to remove Oracle WebCenter Portal and related products from your system.

You should always use the instructions provided in this chapter for removing the software. If you try to remove the software manually, you may experience problems when you try to reinstall the software again at a later time. Following the procedures in this section will ensure that the software is properly removed.

The following topics are covered:

6.1 Deinstalling Oracle WebCenter Portal

The deinstaller will attempt to remove the Oracle home from which it was started. Before you choose to remove your Oracle home, make sure that it is not in use by an existing domain, and also make sure you stop all running processes that use this Oracle home.

This procedure will not remove any WebLogic domains that you have created - it only removes the software in the Oracle home.

Properly removing Oracle WebCenter Portal from your system involves the following tasks:

6.1.1 Stopping Oracle Fusion Middleware

Before deinstalling Oracle Fusion Middleware software components, you should stop all servers and processes.

For instructions, refer to "Starting and Stopping Oracle Fusion Middleware" in Oracle Application Server Administrator's Guide.

To stop Node Manager, see the instructions in "Stopping Node Manager" in Oracle Fusion Middleware Node Manager Administrator's Guide for Oracle WebLogic Server.

6.1.2 Removing Oracle WebCenter Portal Schemas

Run the Repository Creation Utility (RCU) to drop the WebCenter Portal schemas from your database.

For instructions, refer to "Dropping Schemas" in Oracle Fusion Middleware Repository Creation Utility User's Guide.

6.1.3 Removing Oracle Universal Content Management

If you installed Oracle UCM separately from the Oracle WebCenter Portal installation, you must first remove this software separately from the Oracle WebCenter Portal software before you remove Oracle WebCenter Portal.

To remove Oracle UCM 11g from your system, refer to "Deinstalling Oracle WebCenter Content" in Oracle WebCenter Content Installation Guide.

To remove earlier versions of Oracle UCM, refer to Content Server Installation Guide for Microsoft Windows and Content Server Installation Guide for UNIX at the following URL:

http://download.oracle.com/docs/cd/E10316_01/owc.htm

After you remove Oracle UCM, you can then proceed with the deinstallation of Oracle WebCenter Portal.

6.1.4 Removing Oracle WebCenter Portal

Deinstalling Oracle WebCenter Portal involves removing the WebCenter Portal Oracle home and the Oracle Common home directories.

The deinstaller will attempt to remove the Oracle home from which it was started. This procedure will not remove any WebLogic domains that you have created - it only removes the software in the Oracle home.

Before you choose to remove any Oracle home, make sure that it is not in use by an existing domain, and also make sure you stop all running processes that use this Oracle home. After you remove the software, you will no longer be able to use your WebLogic domain.

6.1.4.1 Removing the WebCenter Portal Oracle Home

To start the deinstaller, navigate to the WCP_ORACLE_HOME/oui/bin (on UNIX operating systems) or WCP_ORACLE_HOME\oui\bin (on Windows operating systems) directory and start the deinstaller.

On UNIX operating systems:

./runInstaller.sh -deinstall -jreLoc JRE_LOCATION

On Windows operating systems:

setup.exe -deinstall -jreLoc JRE_LOCATION

Note:

Specify the absolute path to your JRE_LOCATION; relative paths are not supported.

Follow the instructions in Table 6-1 to deinstall Oracle WebCenter Portal.

If you need additional help with any of the deinstallation screens, refer to Appendix B, "Oracle WebCenter Portal Deinstallation Screens" or click Help to access the online help.

Table 6-1 Flow of the Oracle WebCenter Portal Deinstallation Screens

Screen Description and Action Required

Welcome

The installer displays this screen when you are about to deinstall one or more Oracle Fusion Middleware software components.

Deinstall Oracle Home

Verify the Oracle home you are about to deinstall.

Click Deinstall to continue.

On the Warning screen, select whether or not you want the deinstaller to remove the Oracle home directory in addition to removing the software.

Click Yes to have the deinstaller remove the software and Oracle home, No to remove only the software, or Cancel to return to the previous screen.

If you select No, go to 0, "Manually Removing Your Oracle Home Directories" for instructions on how to manually remove your Oracle home directory.

Deinstallation Progress

This screen shows the progress and status of the deinstallation.

Deinstallation Complete

This screen summarizes the deinstallation that was just completed.

Click Finish to dismiss the screen.


6.1.4.2 Removing the Oracle Common Home

This section describes how to remove the oracle_common directory. This directory contains its own deinstaller in oui/bin (on UNIX operating systems) or oui\bin (on Windows operating systems), just like any other Oracle home directory.

To start the deinstaller, navigate to the MW_HOME/oracle_common/oui/bin (on UNIX operating systems) or MW_HOME\oracle_common\oui\bin (on Windows operating systems) directory and start the deinstaller.

On UNIX operating systems:

./runInstaller -deinstall -jreLoc JRE_LOCATION

On Windows operating systems:

setup.exe -deinstall -jreLoc JRE_LOCATION

Note:

Specify the absolute path to your JRE_LOCATION; relative paths are not supported.

After the deinstaller is started, follow the instructions in Table 6-1 to remove the Oracle Common home.

6.1.4.3 Manually Removing Your Oracle Home Directories

If you selected No on the warning screen during deinstallation, you must manually remove your Oracle home directories and all sub-directories. For example, if your WebCenter Portal Oracle home directory was /home/Oracle/Middleware/Oracle_WC1 on a UNIX operating system:

> cd /home/Oracle/Middleware
> rm -rf Oracle_WC1

On a Windows operating system, if your WebCenter Portal Oracle home directory was C:\Oracle\Middleware\Oracle_WC1, use a file manager window and navigate to the C:\Oracle\Middleware directory, then right-click on the Oracle_WC1 folder and select Delete.

The same procedure can be used to manually remove the Oracle Common home (oracle_common) directory.

6.1.5 Removing Oracle WebLogic Server

Instructions for removing Oracle WebLogic Server are provided in "Uninstalling the Software" in Oracle Fusion Middleware Installation Guide for Oracle WebLogic Server.

After the software is removed, you must manually remove the Middleware home directory and all sub-directories. For example, if your Middleware home directory was /home/Oracle/Middleware on a UNIX operating system:

> cd /home/Oracle
> rm -rf Middleware

On a Windows operating system, if your Middleware home directory was C:\Oracle\Middleware, use a file manager window and navigate to the C:\Oracle directory, then right-click on the Middleware folder and select Delete.

6.1.6 Removing Oracle JDeveloper

If you have installed Oracle JDeveloper on your system, refer to "Uninstalling Oracle JDeveloper" in Oracle Fusion Middleware Installation Guide for Oracle JDeveloper (Oracle Fusion Applications Edition) for instructions on how to remove this software from your system.

6.1.7 Removing the Program Groups (Windows Only)

On Windows systems, you must also manually remove the program groups from the Start menu. You can do this by either:

  • Selecting the item in the Start menu, then right-click and select Delete to remove the selected item.

  • Removing the folder from the directory on your system (for example, the C:\Program Data\Microsoft\Windows\Start Menu\Programs folder).

The following program groups should be removed:

  • Oracle Common Home 11g - Home1

  • Oracle WebCenter Portal 11g - Home1

  • Oracle WebLogic

6.1.8 Rebooting Your System (Windows Only)

On Windows operating systems, you should reboot your computer after you have finished removing all your programs to ensure proper cleanup.

6.2 Reinstalling Oracle WebCenter Portal

The installer does not allow reinstallation of Oracle WebCenter Portal in a directory that already contains an Oracle product. To reinstall Oracle WebCenter Portal in the same directory as before, you must follow the instructions in this chapter to deinstall the software, then follow the instructions in Chapter 2, "Installing Oracle WebCenter Portal" to reinstall the software.

If you need to reinstall Oracle WebCenter Portal because of a partial installation or configuration, see important information in "Recovering From a Partial or Interrupted Installation or Configuration" in Oracle Fusion Middleware Installation Planning Guide.
