5.1.1 Stopping Oracle Fusion Middleware

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

Stop the WebLogic Managed Servers.

On UNIX operating systems:

MW_HOME/user_projects/domains/domain_name/bin/stopManagedWeblogic.sh managed_server_nanme admin_url username password

On Windows operating systems:

MW_HOME\user_projects\domains\domain_name\bin\stopManagedWeblogic.cmd managed_server_nanme admin_url username password

Stop WebLogic Administration Server.

On UNIX operating systems:

MW_HOME/user_projects/domains/domain_name/bin/stopWeblogic.sh username password admin_url

On Windows operating systems:

MW_HOME\user_projects\domains\domain_name\bin\stopWeblogic.cmd username password admin_url

For both commands, specify the admin_url using the following format:

http://admin_server_host.admin_server_domain:admin_server_port

For more information about starting and stopping Oracle Fusion Middleware, refer to "Starting and Stopping Oracle Fusion Middleware" in Oracle Fusion Middleware Administrator's Guide.

5.1.2 Removing Oracle WebCenter Schemas

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

5.1.2.1 Starting RCU

Insert the RCU CD-ROM and start RCU from the rcuHome/bin (on UNIX operating systems) or rcuHome\bin (on Windows operating systems) directory:

On UNIX operating systems:

./rcu

On Windows operating systems:

rcu.bat

If you download the RCU .zip file from OTN, then you can also start RCU as shown above from the rcuHome/bin (on UNIX operating systems) or rcuHome\bin (on Windows operating systems) directory on your system.

5.1.3 Removing Oracle Universal Content Management

If you installed Oracle UCM as part of the Oracle WebCenter installation, then you can skip this section.

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. Instructions for doing so can be found in 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 them proceed with the deinstallation of Oracle WebCenter.

5.1.4 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.

5.1.4.1 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 5-1 to deinstall Oracle WebCenter.

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

Table 5-1 Deinstallation Flow

No.	Screen	Description and Action Required
1	Welcome Screen	Click Next to continue.
2	Deinstall Oracle Home Screen	Verify the Oracle Home you are about to deinstall. Click Deinstall to continue.
3	Deinstall Progress Screen	This screen shows the progress and status of the deinstallation.
4	Deinstall Completed Screen	Click Finish to dismiss the screen.

After this is done, you must manually remove the WebCenter Oracle Home directory 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.

5.1.4.2 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 5-1 to remove the Oracle Common Home.

5.1.5 Removing Oracle WebLogic Server

To remove Oracle WebLogic Server:

Start the deinstaller from the WebLogic_Home/uninstall (on UNIX operating systems) or WebLogic_Home\uninstall (on Windows operating systems) directory. You specified the location of the WebLogic Home directory on the Choose Product Installation Directories Screen in Section 2.1.4, "Install Oracle WebLogic Server and Create the Middleware Home".

On UNIX systems:
```
./uninstall.sh
```
On Windows systems:
```
uninstall.cmd
```
On Windows systems, you can also start the deinstaller from the Start menu by selecting Programs > Oracle WebLogic > Uninstall Oracle WebLogic.
Welcome Screen

Click Next.
Choose Components Screen

By default, all components are selected.

Click Next.
Uninstalling WebLogic Platform Screen

Click Done.

After this is done, 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.

5.1.6 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.

5.1.7 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 11.1.1.2.0
Oracle WebCenter 11g - Home1
Oracle WebLogic

5.2 Reinstallation

The installer does not allow reinstallation of an Oracle WebCenter instance in a directory that already contains an Oracle WebCenter instance. To reinstall Oracle WebCenter in the same directory, you have to deinstall and then install it.
