Identity Manager can use one of the following drivers to communicate with the Oracle adapter:
JDBC thin driver
JDBC OCI driver
Since the Oracle Application stored procedures require unencrypted passwords to be passed to some of the stored procedures used for provisioning, you should implement encrypted communications between Identity Manager and the Oracle application resource.
Please read the Oracle publication Oracle Advanced Security Administrators Guide and your JDBC driver’s documentation to validate the level of support for encryption that your specific version of Oracle RDBMS and driver provides.
