Overview of Oracle DCE Integration

This chapter provides brief descriptions of the Distributed Computing Environment (DCE) and the Oracle DCE Integration product. For more detailed information, see the list of related books and papers in "Related Publications" in the Preface of this guide.

This information includes the following:

9.1 System Requirements

Oracle DCE Integration requires Net8 or higher and Oracle8.0.3. It enables Oracle applications and tools to access Oracle8 servers in a DCE environment.

Note:

Oracle DCE Integration is based on the Open Software Foundation (OSF) DCE V1.0 and V1.1, and will be compatible with OSF's future DCE releases.  

Note:

OSF recently merged with another standards group,
X/OPEN, to form The Open Group. This group will continue to support DCE.  

9.2 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, the 2.1.6 clients will not be able to take advantage of external roles.

A DCE Integration 2.3.2 or later client will not be able to 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 2.3.2 or later server in order to connect to a database.

9.3 Overview of Distributed Computing Environment (DCE)

The Distributed Computing Environment (DCE) from the Open Software Foundation (OSF) is a set of integrated network services that work 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.

For more detailed information on DCE, see "Related Publications" in the Preface of this guide.
