If the $ORACLE_BASE is set, this is $ORACLE_BASE/admin/DB_UNIQUE_NAME/wallet, otherwise it is $ORACLE_HOME/admin/DB_UNIQUE_NAME/wallet, where DB_UNIQUE_NAME comes from the initialization parameter file.Although encrypted tablespaces can share the default database wallet, Oracle recommends you use a separate wallet for transparent data encryption functionality by specifying the ENCRYPTION_WALLET_LOCATION parameter in the sqlnet.ora file. The TDE full form is transparent data encryption. TDE can encrypt entire application tablespaces or specific sensitive columns. With the release Oracle 18c later 19c this functionality was added again step by step. TDE tablespace encryption encrypts all of the data stored in an encrypted tablespace and the corresponding redo data. A variety of helpful information is available on this page including product data sheet, customer references, videos, tutorials, and more. If the target CDB didn't have TDE, you should configure and enable the wallet for the database. ( 1) Before attempting to enable encryption, a wallet/keystore must be created to hold the encryption key. TDE encrypts sensitive data stored in data files. Encrypted data is transparently decrypted for a database user or application that has access to data. Existing tablespaces can be encrypted online with zero downtime on production systems or encrypted offline with no storage overhead during a maintenance period.
