Dualog Connection Suite - Uninstalling the Oracle Database 11G


Connection Suite is a conglomerate of modules held together by a database running in the background. This database, known as Oracle, is running independently from Connection Suite and needs to be uninstalled separately when completely redirect.jpg removing Connection Suite from the Dualog PC.

It is critical that each uninstallation step is thoroughly followed to be able to prospectively redirect.jpg reinstall Connection Suite on the same computer. Skipping a step might cause issues during the reinstallation procedure.


Oracle is one of the most widely used databases in the world and it might be in use by other applications on the same PC that can be disrupted if Oracle is uninstalled. Please verify with your IT department if there are other applications or programs sharing Oracle with Dualog before proceeding.


To perform the following procedure, you must have complete access to the Dualog machine (redirect.jpg find the physical Dualog PC onboard.)
