Introduction to Oracle DCE Integration

Introduction to Oracle DCE Integration
The
integrated network services that works across multiple systems to provide a
distributed environment. The network services include remote procedure calls
(RPCs), directory service, security service, threads, distributed file service, diskless
support, and distributed time service.
DCE is the middleware between distributed applications and the operating
system/network services and is based on a client/server model of computing. By
using the services and tools that DCE provides, users can create, use, and maintain
distributed applications that run across a heterogeneous environment.
Oracle DCE Integration enables Oracle applications and tools to access Oracle
database servers in a DCE environment.

System Requirements

Oracle DCE Integration requires Oracle Net Services and Oracle Database. It is
based on the Open Software Foundation (OSF) DCE protocol (V1.1 and later).
Note that OSF has merged with X/OPEN, another standards group, to form The
Open Group. This group is committed to continuing DCE support.

Backward Compatibility

Oracle servers running DCE Integration 2.3.2 and later are backward compatible
with clients running SQL*Net/DCE 2.1.6 or 2.2.3; however, Release 2.1.6 clients
cannot take advantage of external roles.
A client running DCE Integration 2.3.2 or later cannot connect to a SQL*Net/DCE
2.1.6 or 2.2.3 server. A DCE Integration Release 2.3.2 or later client requires a Release
2.3.2 or later server in order to connect to a database.

Components of Oracle DCE Integration

Oracle DCE Integration has two components: DCE Communication/Security and
DCE CDS Native Naming.
