Table of Contents Overview of DCE Technology Components

B.3 Implementations

All major IBM platforms implement DCE. The various implementations are detailed below.

The Open Software Foundation (OSF) on April 7th 1995 named IBM's AIX Distributed Computing Environment (AIX/DCE) as the industry's first certified implementation. The certification process assures customers that any implementation of DCE, a base for open, distributed, client/server computing, fully interoperates with other certified DCE solutions. IBM intends to submit all of its DCE implementations for certification with OS/2 DCE the next in line.

B.3.1 MVS

DCE support is provided in the following features of MVS/ESA SP V5 OpenEdition:

• MVS/ESA OpenEdition DCE Base Services Feature
• MVS/ESA OpenEdition DCE User Data Privacy Feature
• MVS/ESA OpenEdition DCE Application Support (orderable as a separate product)

IBM intends to upgrade MVS/ESA OpenEdition DCE to OSF DCE Version 1.1. OSF DCE Version 1.1 will provide a foundation for RACF-DCE interoperation and for support of single sign-on between MVS/ESA and DCE environments.

MVS/ESA OpenEdition DCE will provide support for DCE RPC over SNA networks in addition to the TCP/IP networks supported today.

IBM also intends to enhance and extend the set of MVS/ESA OpenEdition DCE servers. The MVS/ESA OpenEdition DCE Application Support Program Product will be enhanced to exploit the security extensions provided in the MVS/ESA OpenEdition DCE Base Services and additional IMS transaction types will be supported.

New MVS/ESA OpenEdition DCE servers will include DCE Security Server and DFS Program Products.

B.3.2 VM

DCE support is provided in VM/ESA V2 with OpenEdition VM/ESA. VM/ESA V2 OpenEdition is based on OSF's DCE V1.02 and provides DCE RPC, DCE Threads, DCE Cell Directory Service (CDS) client support and DCE Security Service client support.

B.3.3 OS/400

• Remote Procedure Call (RPC)
• Cell Directory Client function
• Security Client function
• Time Services

In order to develop DCE applications in the OS/400 environment the following is required:

• Integrated Language Environment C/400

B.3.4 AIX/6000

The IBM DCE for AIX family of products for AIX/6000 V3.2.5 was extended in October 1994 with the addition of two new members:

• IBM DCE Manager for AIX V1.3
• IBM DCE NFS to DFS Authenticating Gateway for AIX V1.3

• IBM DCE Base for AIX V1.3
• IBM DCE Security Server for AIX V1.3
• IBM DCE Cell Directory Server for AIX V1.3
• IBM DCE Global Directory Server for AIX V1.3
• IBM DCE Enhanced Distributed File System for AIX V1.3
• IBM DCE Threads for AIX V1.3
• IBM DCE Global Directory Client for AIX V1.3

IBM DCE for AIX V1.3 is not compatible with AIX V4. However, IBM plans to provide these functions on an AIX V4 base in 1995.

B.3.5 OS/2 and Windows

DCE support is provided in:

• DCE Software Developer's Kit (SDK) for OS/2 and Windows V1.0
• DCE Client for OS/2 V1.0
• DCE Client for Windows V1.0

DCE for OS2 and DCE for Windows consist of:

• Security Services
• Directory Services
• Time Services
• RPC
• Threads
