Be extra cautious when enabling TDE in RAC. We could not find a match for your search. We should let the database know where to find the wallet by setting related parameters. TDE is part of the Oracle Advanced Security, which also includes Data Redaction. Due the latest advances in chipsets that accelerate encrypt/decrypt operations, evolving regulatory landscape, and the ever evolving concept of what data is considered to be sensitive, most customers are opting to encrypt all application data using tablespace encryption and storing the master encryption key in Oracle Key Vault. Customers can keep their local Oracle Wallets and Java Keystores, using Key Vault as a central location to periodically back them up, or they can remove keystore files from their environment entirely in favor of always-on Key Vault connections. A new parameter called skip_tde_key_import is introduced. Note that TDE is the only recommended solution specifically for encrypting data stored in Oracle Databasetablespace files. It stops unauthorized attempts from the operating system to access database data stored in files, without impacting how applications access the data using SQL. If you have any benchmark about comparing those algorithm, please comment your thinking below. Prepare Wallet for Node 2.
