3.1.3 CELL_OFFLOAD_DECRYPTION

The CELL_OFFLOAD_DECRYPTION initialization parameter enables decryption offload to Oracle Exadata Storage Servers. This decryption applies to both encrypted tablespaces and encrypted columns. When the value of the parameter is set to TRUE, decryption can be offloaded to cells. The default value of the parameter is TRUE. If the parameter is set to FALSE at the system level, then the database performs all decryption with cells serving blocks. You can set CELL_OFFLOAD_DECRYPTION dynamically with the SQL ALTER SYSTEM command. For example:

SQL> ALTER SYSTEM SET CELL_OFFLOAD_DECRYPTION = FALSE;
