I am trying to implement oracle Transparent Data Encryption.
I have updated sqlnet.ora with
ENCRYPTION_WALLET_LOCATION = (SOURCE =
(METHOD = FILE)
(METHOD_DATA =
(DIRECTORY = D:\app\ora12c\WALLETS\)))
Then I restart service and tried to run command.
ALTER SYSTEM SET ENCRYPTION KEY IDENTIFIED BY "biju$7777"
from SYS (SYSDBA) user, But I got following error
SQL Error: ORA-28368: cannot auto-create wallet
28368. 0000 - "cannot auto-create wallet"
*Cause: The database failed to auto create an Oracle wallet. The Oracle
process may not have proper file permissions or a wallet may
already exist.
*Action: Confirm that proper directory permissions are granted to the Oracle
user and that neither an encrypted or obfuscated wallet exists in
the specified wallet location and try again.
