It has been many years since I had the need to uninstall Oracle software from a Unix server. In this case it was Oracle10g for Solaris (SPARC 64-bit). Thought maybe I could use the OUI found on the DVD. So wrong.
The problem with using the OUI version from the DVD is OUI will not allow you to remove any components. The “Remove” button is unavailable even after you select a component to uninstall.
You cannot deinstall at this time. For more information, click “Help”.
Using the “Help” button gives an explanation on why it’s not available, but no solution really.
Although OUI can list all products previously installed with another installer (orainst), it cannot deinstall them.
The proper way to uninstall is found in the Oracle® Database Installation Guide 10g Release 2 (10.2) for Solaris Operating System (SPARC 64-Bit). Use the OUI found in:
Uninstalling is a simple thing to do, however I forgot how to uninstall after not performing this action for many years. As they say, RTFM.
