Uninstalling Oracle Database XE

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 with Siebel Tools, or 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.

It is recommended that you uninstall Oracle Database XE if you installed it for use with Siebel Tools or 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 Innovation Pack 2017 (version 17.0) and roll back to Siebel Innovation Pack 2015 (version 15.0). Uninstall Oracle Database XE before you uninstall or roll back Siebel Tools or Siebel Web Client. For patchset uninstallation (rollback), see Siebel Patchset Installation Guide for Siebel CRM, 1614310.1 (Article ID) on My Oracle Support.

NOTE:  When you uninstall Siebel Tools or Siebel Web Client, in a full installation or rollback uninstallation (including rollback of a patchset release), Oracle Database XE and 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 procedure below, 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 Tools or Siebel Web Client. Then navigate to the directory where the Oracle Database XE installer is located.

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

   • Siebel_Image\Windows\Client\Siebel_Tools\Disk1\stage\XE\64\Disk1
   • 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 Innovation Pack 2017.

2. To start the Oracle Database XE installer, double-click setup.exe.
3. Click Remove.
4. After uninstalling Oracle Database XE, restart the computer.
