Rolling Back the Siebel Application Interface

Use the following procedure to roll back the current release of the Siebel Application Interface software on a single computer and revert to the previously installed software version. You can do this only when you have installed the current release as a migration installation for an existing installation of Siebel CRM version 8.1.1.x, version 8.2.2.x, version 15.x, or version 16.x.

NOTE:  To be able to roll back the current release and revert to a previous version, you must have retained the backup directory to which the previous installation was moved during the migration installation. During that installation, if the original SWSE installation directory was named sweapp, then it was renamed from sweapp to sweapp_pre17.0.

NOTE:  This topic describes only rolling back a migration installation, not rolling back a patchset installation. For patchset uninstallation (rollback), see Siebel Patchset Installation Guide for Siebel CRM, 1614310.1 (Article ID) on My Oracle Support.

This topic is part of Uninstalling Siebel Enterprise Server or Siebel Application Interface.

To roll back the Siebel Application Interface

1. Review all of the information in About Uninstalling Siebel Business Applications, particularly the requirements and limitations.
2. Verify that the renamed original installation directory, such as sweapp_pre17.0, exists.
3. Stop the Web server.
4. You must use the correct rollback uninstallation method for your situation, as follows. For more information, see Requirements for Uninstalling Siebel Business Applications.
   • If you originally installed Siebel CRM version 8.1.1 (using the InstallShield installer) and are now rolling back to Siebel CRM version 8.1.1 through version 8.1.1.7, then use the Oracle Universal Installer uninstallation option to uninstall Siebel CRM version 17.0. Follow the procedure described in Uninstalling the Siebel Application Interface, but do not remove configuration data. After performing this task, go to Step 9. (Step 5 through Step 8 do not apply in this case.)
   • If you are rolling back to Siebel CRM version 8.1.1.8 or later, version 8.2.2.x, version 15.x, or version 16.x, then use the manual steps that follow. Go to the next step. (Step 5 through Step 8 apply in this case only.)
5. Delete the directory representing the current installation of Siebel Application Interface for the current release. For example, if the directory name is Siebel_AI or sweapp, then delete this directory.
6. Rename the backup directory representing the previously installed software to use the original installation directory name for SWSE. Rename the original (renamed) directory, such as sweapp_pre17.0, to sweapp (depending on your original installation directory name).
7. Delete the program folder that was created for the current release.

   The program directory was defined based on the installation directory. For example, for an installation directory of C:\siebel\eapps, the program folder is Siebel_Home_c_siebel_eapps.

8. If you rolled back to Siebel CRM version 8.1.1.8 or later, version 8.2.2.x, version 15.x, or version 16.x, then verify the version number by using the opatch command, as described in Verifying Installation for Siebel Business Applications.
9. Restart the Web server where you originally installed the SWSE.
10. Run the SWSE Configuration Wizard, as necessary, to perform any required configuration tasks if you had removed the SWSE configuration on the Web server before performing the migration installation of the current version.

    NOTE:  You must use the SWSE Configuration Wizard for the version of the software that you rolled back to. Additional requirements apply to the post-rollback environment

11. If Oracle Configuration Manager was not configured before you performed a migration installation of Siebel Application Interface, then, after a rollback to the original installation of SWSE, you must configure this instance of Oracle Configuration Manager manually in order for it to function properly.
