Customers using TDE tablespace encryption get the full benefit of compression (standard and Advanced Compression, as well as Exadata Hybrid Columnar Compression (EHCC)) because compression is applied before the data blocks are encrypted. The environment is single instance database. The TDE full form is transparent data encryption. If you have any benchmark about comparing those algorithm, please comment your thinking below. If you import this data into an encrypted tablespace, it will be encrypted, if you import into an unencrypted tablespace, then the data will be unencrypted. Individual table columns that are encrypted using TDE column encryption will have a much lower level of compression because the encryption takes place in the SQL layer before the advanced compression process. This approach works for both 11g and 12c databases. It is no longer required to include the "file_name_convert" clause. administer key management set keystore open identified by oracledbwr; SQL> administer key management set key using tag oracledbwr_Tablespace_TDE force keystore identified by oracledbwr with backup using TDE_backup; I have extensive experience in data related teams, giving me a variety of skills and the ability to work .
