Specifying the Oracle Wallet Location in the SQLnet.ora File

To implement Transparent Data Encryption on either columns or tablespaces, you must specify an Oracle Wallet location in the sqlnet.ora configuration file before creating the database instance.

After creating the database instance, the database installation script creates an Oracle Wallet in the location specified in sqlnet.ora. An external security module adds a Master Encryption Key to the Wallet.

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

To specify the Oracle Wallet location in the SQLnet.ora files

1. Change to the network administration directory of your Oracle Self-Service E-Billing database server, for example:
   • UNIX. $ORACLE_HOME/network/admin
   • Windows. %ORACLE_HOME%\network\admin
2. Open the sqlnet.ora file, and use the ENCRYPTION_WALLET_LOCATION parameter to specify the Oracle Wallet Location.

   The following example shows a sqlnet.ora file that uses the /export/home/oracle11/wallet directory as the Oracle Wallet Location:

   ENCRYPTION_WALLET_LOCATION=

   (SOURCE=

   (METHOD=FILE)

   (METHOD_DATA=

   (DIRECTORY=/export/home/oracle11/wallet)

   )

   )

   CAUTION:  The wallet location directory must have an absolute path and end with a right parenthesis. Verify that there are no invisible characters at the end of the directory path. These characters can cause Oracle Database not to recognize the directory.

3. Save and close the sqlnet.ora file.
