Hi,
How could I repair my database and table if my database or table index file is corrupted (no backup available)?
Is it the way to recover it?

Database Corrupted
- Replace with original database which pre-stored in other directory

Index corrupted
-Replace CDX file with original CDX file, and issue REINDEX


is it true? Any other better ways to recover its programmatically without 3rd party tool?

Thank you
