ORA-28315
Oracle ORA-28315: Encryption Key Mismatch
Description
This error indicates a problem with the encryption keys used for an Oracle tablespace. It typically occurs when the database cannot verify the master key or the tablespace key for a data file during startup or access.
Error Message
ORA-28315: encryption key mismatched for file # string
Known Causes
3 known causesIncorrect Encryption Wallet
The encryption wallet containing the master key is either missing, corrupted, or not accessible to the database instance. This prevents the database from decrypting the tablespace.
Wallet Sharing Issues
The encryption wallet is incorrectly shared between multiple databases. Each database should have its own unique wallet or a properly configured shared wallet setup.
Corrupted Tablespace Key
The tablespace encryption key itself has been corrupted or altered, making it unusable for decryption.
