Suppose if the databases control file is lost permanently (no backup).
Can we retrieve the data from data file in Oracle database?
In general – ‘yes’. But the circumstances matter. If you know what should be in the control file then you can recreate it (or rather, them; they should be multiplexed anyway) – see this article for example. That uses the
create controlfilecommand with appropriate options and parameters to recreate the control file matching your existing data files. Really make sure you understand what it’s doing and what impact it may have – you don’t want to make things worse than they already are.Or google for “oracle recover control file”.
Don’t rely on this being possible though – it’s no substitute for a real backup and recovery strategy.
