I have a client who recently was forced to reformat and reinstall Windows Server 2008 R2. Their ORACLE_HOME (Oracle 11g) and all of the data was located on a D: drive that was not reformatted. Can I associate this pre-existing ORACLE_HOME with Windows, or do I need to reinstall?
I'm thinking that all I should need to do is add the missing registry entries, recreate the listener, and use oradim to recreate the system service. If this would work, am I missing anything?
