6 Deinstalling Oracle WebCenter

This section describes how to remove Oracle WebCenter 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 Deinstallation Instructions

Follow the instructions in this section to remove Oracle WebCenter and related software from your system. The following tasks should be completed:

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 Fusion Middleware Administrator's Guide.

6.1.2 Removing Oracle WebCenter Schemas

Run the Repository Creation Utility (RCU) to drop the WebCenter 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 installation, you must first remove this software separately from the Oracle WebCenter software before you remove Oracle WebCenter.

To remove Oracle UCM 11g from your system, refer to "Deinstalling Oracle Enterprise Content Management Suite" in Oracle Fusion Middleware Installation Guide for Oracle Enterprise Content Management Suite.

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.

6.1.4 Removing Oracle WebCenter

Deinstalling Oracle WebCenter involves removing the WebCenter 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 Oracle Home

To start the deinstaller, navigate to the WebCenter_ORACLE_HOME/oui/bin (on UNIX operating systems) or WebCenter_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.

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

Table 6-1 Deinstallation Flow

No. Screen Description and Action Required

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 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 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 Oracle Fusion Middleware Installation Guide for Oracle JDeveloper 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\Programs folder. As an example (the folder names and program group names on your system may be different), you might remove the following from C:\Documents and Settings\All Users\Start Menu\Programs:

  • Oracle Fusion Middleware 11.1.1.5.0

  • Oracle WebCenter 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 Reinstallation

The installer does not allow reinstallation of Oracle WebCenter in a directory that already contains an Oracle product. To reinstall Oracle WebCenter 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" to reinstall the software.
