Installation Guide for Oracle Self-Service E-Billing > Configuring the Oracle Database >

Opening the Encrypted Wallet

The external security module stores the master encryption key in an Oracle wallet. The database must load the master encryption key into memory before it can encrypt or decrypt columns. Opening the wallet allows the database to access the master encryption key.

NOTE:  Once the wallet is open, it remains open until you shut down the database instance. When you restart the instance, you must open the wallet again if it is set to manual open mode.

This task is a step in Process of Implementing Transparent Data Encryption and inProcess of Implementing Tablespace Encryption.

Follow these steps to open the encrypted wallet.

To open the encrypted wallet

1. Change to the directory of the Oracle Self-Service E-Billing database installation files, where EDX_HOME is the directory where you installed Oracle Self-Service E-Billing:
   • UNIX. EDX_HOME/db/ebilling/oracle
   • Windows. EDX_HOME\db\ebilling\oracle
2. Type Ant to run the build script.

   By default, Ant picks up the build.xml file in the current directory.

3. Select Option 3, Encrypt sensitive data.
4. Select option 3, Open Oracle Wallet.

NOTE:  If you forcibly shutdown an encrypted database (a shutdown abort), the following error message might occur when restarting the database without opening the wallet. This error can occur because during recovery background processes might require access to encrypted redo and undo logs.

ORA-28365: wallet is not open

ORA-28365: wallet is not open

ORA-00600: internal error code, arguments: [kcrp_init_1], [], [], [], [], [],

[], []

The Wallet must be open before opening the database:

SQL> startup mount;

SQL> alter system set wallet open identified by "password";

SQL>alter database open;
