Setting the Master Encryption Key Using the Ant Encryption Menu

When implementing TDE column encryption, you can optionally set the Master Encryption Key, using the Ant Encryption menu after creating the Oracle Billing Insight database, but before encrypting the columns. Setting the Master Encryption Key using the Ant Encryption menu is only necessary if you did not set the TDE_ENCRYPT_OLAPCOLUMN and TDE_ENCRYPT_OLTPCOLUMN property values to Y in the BillingInsight.properties file before running the Oracle Billing Insight database installation using Ant.

This task is a step in Process of Implementing TDE Column Encryption.

To set master encryption key using the Ant Encryption menu

1. Change to the directory of the Oracle Billing Insight database installation files. In the directory, EDX_HOME is the location where you installed Oracle Billing Insight.
   • UNIX. EDX_HOME/db/oracle
   • Windows. EDX_HOME\db\oracle
2. Enter Ant to run the build script.

   By default, the Ant command runs the build.xml file in the current directory.

3. Select Option 2, Setup Database Encryption.
4. Select Option 1, Set Master Encryption Key. Enter your password twice.

   Ant prompts you to create an Oracle Wallet password when it is ready to create the Master Encryption Key.

5. Specify a password for the Oracle Wallet, then enter it again.
6. Specify whether you want to open the Oracle Wallet automatically when the database instance restarts.

   It is recommended to enter Y to keep the Oracle Wallet open when the database restarts. If you enter N, then you will have to open the Wallet each time you restart the database.
