Uninstalling Siebel Enterprise Server or Siebel Application Interface

This topic describes how to uninstall Siebel Enterprise Server and Siebel Application Interface software for the current release. Both full uninstallation and rollback uninstallation are described. Rollback uninstallation rolls back a migration installation of these modules. With a rollback uninstallation, you roll back to the previously installed software version (whether Siebel CRM version 8.1.1.x, version 8.2.2.x, version 15.x, or version 16.x).

In a full uninstallation, the installed Siebel Enterprise Server software components are uninstalled, which might include Siebel Gateway, Siebel Server, Database Configuration Utilities, EAI Connector, Siebel Enterprise Cache, and Siebel Constraint Engine. Some components might have been installed on a single computer or operating system instance, or different components might have been installed on multiple computers or operating system instances.

Siebel Application Interface is always uninstalled as a separate task, for either full uninstallation or rollback uninstallation. In the current release, Siebel Application Interface is installed in a different location than the other Siebel Enterprise Server components, although they use the same installer software. Siebel Application Interface replaces the Siebel Web Server Extension (SWSE), which in prior releases used a separate installer.

CAUTION:  Before you proceed with any uninstallation task, review all of the information in About Uninstalling Siebel Business Applications, particularly the requirements and limitations.
