AIX Distributed Computing Environment (DCE)

Distribute the POWER


The AIX(r) Distributed Computing Environment (DCE) product family Version 1.3 extends the industry-leading distributed computing technology to the RISC System/6000(r) (RS/6000(tm)) workstations and servers.


AIX DCE Version 1.3:

Open, distributed computing for the 1990s

DCE is the foundation for distributed, client/server computing in the open enterprise for the 1990s. With DCE, you have access to enterprisewide data and hardware. Even better, you can develop distributed applications in a network-independent manner without having to develop generic functions like RPC, security, naming, and time services.

So, if your business needs programs like distributed decision support, process control, office productivity tools, program distribution and on- line transaction processing (OLTP) systems, DCE is your solution.

Best of all, DCE allows you to exploit the unique power and flexibility of RS/6000 workstations and servers to run a broad range of distributed applications. And, DCE builds on the commercial strength of AIX(tm), an enhanced version of the UNIX(r) operating system primed with features like real-time support, system management tools, and superb file and volume capabilities.

The following components comprise AIX DCE:

In addition, the DCE for AIX family now provides advanced monitoring of the DCE environment through the DCE Manager for AIX and an NFS to DFS authenticating gateway (both separately orderable products).

Here are some of the ways you can put DCE to work for you:

Why RISC System/6000?

Here are some of the reasons why IBM's RS/6000 stands out as the best solution for your technical and commercial computing needs:

IBM's innovative POWER Architecture (tm), combined with a 32-bit Micro Channel(r) bus, for extraordinary processing power and floating-point capability.

Impressive benchmarks, from 8.8 double-precision Linpack MFLOPS[1] in the POWERstation/POWERserver 230 to 38.1 MFLOPS in the POWERserver 980B. This makes RS/6000 the perfect choice for numeric-intensive jobs and complex graphics applications.

Support for thousands of technical and commercial applications that gives you the flexibility to run everything from engineering design packages to business accounting in multiuser environments.

Interoperability with most IBM and non-IBM systems, a must in today's multivendor environments. DCE has been tested for interoperability with DCE on other IBM platforms, such as OS/2(r), and on other vendors' offerings.

World-class service and support, available with every RS/6000 POWERstation and POWERserver.

Open, distributed, commercial power with DCE, Encina for AIX, and CICS/6000, so you can implement b usiness-criticalapplications on RS/6000 POWERstations and POWERservers.
