Enable TDE in the database

You must protect sensitive data by encryption. Oracle Empirica Signal 9.1 supports encrypted tablespaces in an Oracle Database where Transparent Data Encryption (TDE) is enabled.

Before upgrading from Oracle Empirica Signal 8.1.x to Oracle Empirica Signal 9.1, perform the following steps:

1. Export all tablespaces from the 8.1.x database.
2. Import all tablespaces from the 8.1.x database into encrypted tablespaces in the 9.1 database.
3. Enable TDE in the 9.1 database.
