B.1 Deinstalling Oracle Service Bus 11g Release 1 (11.1.1.3)

This topic contains procedures for deinstalling Oracle Service Bus 11g Release 1 (11.1.1.3) and contains the following sections:

Deinstalling Oracle Service Bus Oracle Home
Deinstalling Oracle Common Home

B.1.1 Deinstalling Oracle Service Bus Oracle Home

The deinstaller attempts to remove the Oracle Home directory from which it was started. Before you choose to remove your Oracle Service Bus Oracle Home directory, make sure that it is not in use by an existing domain and that you stop all running processes that use this Oracle Home.

Deinstalling Oracle Service Bus will not remove any WebLogic administration domains that you have created—it only removes the software in the Oracle Service Bus Oracle Home directory.

This topic describes how to deinstall Oracle Service Bus 11g Release 1 (11.1.1.3) using the graphical, screen-based deinstaller. However, you can also perform a silent deinstallation using a response file. A deinstall response file template that you can customize for your deinstallation is included in the Disk1/stage/Response directory on UNIX, or in the Disk1\stage\Response directory on Windows.

Perform the following steps to deinstall Oracle Service Bus Oracle Home using the graphical, screen-based deinstaller:

Verify your Oracle Service Bus Oracle Home is not in use by an existing domain.
Stop all processes that use the Oracle Service Bus Oracle Home.
Open a command prompt and move (cd) into the Oracle_Service_Bus_Oracle_Home/oui/bin directory (UNIX) or the Oracle_Service_Bus_Oracle_Home\oui\bin directory (Windows).
Invoke the Deinstaller from command line using the -deinstall option. For example:

On UNIX:
```
./runInstaller -deinstall
```
On Windows:
```
setup.exe -deinstall
```
The Welcome screen appears.
Click Next. The Deinstall Oracle Home screen appears.
In the Deinstall Oracle Home screen, you can save a response file that contains the deinstallation settings before deinstalling. Click Deinstall. The Deinstall Progress screen appears. This screen shows the progress and status of the deinstallation. If you want to quit before the deinstallation is completed, click Cancel.

Click Finish after the deinstallation progresses to 100%. The Deinstallation Complete screen appears.
Click Finish on the Deinstallation Complete screen to exit the deinstaller.

B.1.2 Deinstalling Oracle Common Home

The ORACLE_COMMON_HOME directory located in the MW_HOME directory contains the binary and library files required for Oracle Enterprise Manager Fusion Middleware Control and Java Required Files (JRF). Before you deinstall the ORACLE_COMMON_HOME directory, ensure that no other Oracle Fusion Middleware software, such as Oracle SOA Suite, depends on ORACLE_COMMON_HOME. You cannot deinstall the ORACLE_COMMON_HOME directory until all software that depends on it has been deinstalled.

Perform the following steps to deinstall the ORACLE_COMMON_HOME directory:

Stop all processes that use the ORACLE_COMMON_HOME directory.
Deinstall your Oracle Service Bus Oracle Home by performing the steps in Deinstalling Oracle Service Bus Oracle Home.
Open a command prompt and move (cd) into the ORACLE_COMMON/oui/bin/ directory (on UNIX) or the ORACLE_COMMON_HOME\oui\bin\ directory (on Windows).
Invoke the Deinstaller from command line using the -deinstall option and the -jreLoc option, which identifies the location where Java Runtime Environment (JRE) is installed. For example:

On UNIX:
```
./runInstaller -deinstall -jreLoc FULL_PATH_TO_JRE_DIRECTORY
```
On Windows:
```
setup.exe -deinstall -jreLoc FULL_PATH_TO_JRE_DIRECTORY
```
The Welcome screen appears.
Click Next. The Select Deinstallation Type screen appears.
Select the Deinstall Oracle Home option at the top of the Select Deinstallation Type screen.

Note:
The path to the ORACLE_COMMON_HOME directory appears in the text describing the Deinstall Oracle Home option.

Click Next. The Deinstall Oracle Home screen appears.
Confirm the correct ORACLE_COMMON_HOME directory is listed and click Deinstall.

The Deinstallation Progress screen appears, along with a Warning dialog box prompting you to confirm that you want to deinstall the ORACLE_COMMON_HOME directory.
Click Yes on the Warning dialog box to confirm you want to remove the ORACLE_COMMON_HOME directory. The deinstallation begins.
Click Finish after the deinstallation progresses to 100%. The Deinstallation Complete screen appears.
Click Finish on the Deinstallation Complete screen to exit the deinstaller.
