DCE integration
Distributed Computing Environment (DCE) integration enables users to transparently use Oracle tools and applications to access Oracle servers in a DCE environment. The Oracle DCE integration product consists of two major components:
DCE communications/security adapter
DCE CDS (cell directory service) naming adapter
The DCE communications/security adapter provides:
- Authenticated remote procedure call (RPC)
RPC is the transport mechanism that enables multivendor interoperability for DCE integration. RPC also uses additional DCE services, including directory and security services, to provide location transparency and secure distributed computing.
- Integrated security
DCE integration works with the DCE security service to provide security within DCE cells. It enables a user logged onto DCE to securely access any Oracle application without specifying a username or password. This function is referred to as external authentication to the database. In addition, clients and servers not running DCE authentication services can interoperate with systems that have DCE security by specifying an Oracle password.
- Data privacy and integrity
DCE integration uses multiple levels of security to ensure data authenticity, privacy, and integrity. Users are provided with a range of choices, from no protection to full encryption for each connection, with a guarantee that no data has been modified in transit.
