DIA-28374
typed master key not found in wallet
Cause
An attempt is being made to access an encrypted tablespace or redo logs with a typed master key that does not exist in the wallet.
Action
Copy the correct Oracle Wallet from the instance where the tablespace was created. Close and open the keystore if the keystore was already open on the database where the keystore was copied. For a PDB unplug/plug or clone operation, verify that the keys were correcly exported and imported by listing the wallet contents using mkstore or orapki. Ensure that the TDE_CONFIGURATION is set to "OKV|FILE" if an external keystore (OKV/KMS) is being used.
