Oracle GRID install failed -INS-40404
Posted by FatDBA on November 9, 2016
Many times while doing some crude deletion or cleanup of GRID directories you have faced an error with the GUI or at the CLI during the progress when you were almost sure that you have deleted everything what is needed.
Bam! right at that moment an error appears saying “The installer has detected a configured instance of Oracle grid infrastructure software on the server” with error code INS-40404.
You tried recalling everything you did to clean and remove every trace of it …. No Luck 😦
Solution to the problem is:
Go to oracle folder under /etc directory.
Remove the ‘ocr.loc’ file which keeps on pointing the local ocr locations.
Hope It Helps!
