You can perform other keystore operations, such as exporting TDE master encryption keys, rotating the keystore password, merging keystores, or backing up keystores, from a single instance only. This parameter has been deprecated.Oracle recommends that you use the WALLET_ROOT static initialization parameter and TDE_CONFIGURATION dynamic initialization parameter instead. Oracle data encryption is called Transparent Data Encryption (TDE). Transparent Data Encryption (TDE) column encryption protects confidential data, such as credit card and Social Security numbers, that is stored in table columns..
