Uninstalling Oracle Database XE

Oracle Database XE was used for the local or sample database with previous versions of Siebel CRM. It is still installed with the Siebel Web Client installer in Siebel CRM 17.0, and is used through Siebel CRM 20.7. The local database now uses Oracle Database SE2 and the sample database is no longer supported. This topic describes how to uninstall Oracle Database XE when it is no longer needed.

Note: Performing a full uninstallation of Siebel Mobile Web Client or restoring a prior release does not uninstall Oracle Database SE2. If you need to uninstall Oracle Database SE2, see the documentation for this product on Oracle Help Center.

Use the following procedure to uninstall Oracle Database XE. You can use this procedure if you previously installed Oracle Database XE and the local database or sample database with Siebel Web Client. Uninstalling Oracle Database XE also uninstalls the local database or the sample database. (You can also uninstall Oracle Database XE if you installed it for an earlier version of Siebel Tools.)

It is recommended that you uninstall Oracle Database XE if you installed it for use with Siebel Mobile Web Client but then determine that you will not use it. For example, you would uninstall Oracle Database XE if you uninstall Siebel CRM 17.0 or later and roll back to Siebel CRM 15.0. Uninstall Oracle Database XE before you uninstall or roll back Siebel Web Client. For full uninstallation of the current release or restoring a prior release, see Uninstalling Siebel CRM.

Note: Performing a full uninstallation of Siebel Mobile Web Client or restoring a prior release does not uninstall Oracle Database XE. The local database or the sample database are not uninstalled. In addition, the ODBC data source created for Oracle Database XE is not deleted in these uninstallation cases.

As an alternative to the following procedure, you can use one of the following methods:

• Uninstall Oracle Database Express Edition from the Windows Control Panel.

• Uninstall Oracle Database Express Edition from Programs and Features.

After uninstalling Oracle Database XE, restart the computer.

To uninstall Oracle Database XE and the local database or sample database

1. In Windows Explorer, navigate to the Siebel image location for the Siebel release from which you installed Oracle Database XE with Siebel Web Client (Siebel CRM 20.7 and earlier). Then navigate to the directory where the Oracle Database XE installer is located.

   Navigate to the following location, based on the Siebel software for which you are uninstalling Oracle Database XE:

   • Siebel_Image\Windows\Client\Siebel_Web_Client\Disk1\stage\XE\64\Disk1

     In this path, Siebel_Image is the directory for your version-specific Siebel network image, such as C:\Siebel_Install_Image\17.0.0.0, for Siebel CRM 17.0.

2. To start the Oracle Database XE installer, double-click setup.exe.

3. Click Remove.

4. After uninstalling Oracle Database XE, restart the computer.

5. Delete the directory SIEBEL_CLIENT_ROOT\oraclexe.
