This IBM Redbook recommends strategies that you can use to replace the Distributed Computing Environment (DCE) dependencies in your environment and move to new technologies. The following topics are covered: - DCE overview and recap - Replacement technologies - Replacement strategies - Replacement scenarios - Replacement coding examples This book is a valuable information source if you are an executive, administrator, or developer of an IBM customer environment that uses IBM DCE for a distributed systems and application infrastructure. Although strategies for replacing DCE are described, the book does not cover strategies for replacing dependencies to IBM products that use DCE, such as DFS and TXSeries.

This redbook, the result of a residency conducted at the ITSO Austin Center, was written to assist those individuals who need to understand the benefits, planning, installation, administration, and basic problem determination of the Directory and Security Server for OS/2 Warp product. We describe many of the benefits that can be reaped with use of the Directory and Security Server for OS/2 Warp. These benefits result from the integration of OSF/DCE Version 1.1 and the existing OS/2 LAN Server architecture. This integration is described in detail to help you understand and appreciate the power and scalability of DSS. A description of the core DCE components is also included for the DCE novice. As products gain features and capabilities, it becomes increasingly important to plan the implementation carefully. We discuss planning and design issues so that the installation is not only successful but also flexible enough to allow for evolving business needs. Poor planning can result in costly reconfiguration and unnecessary downtime. Sample scenarios are also included, some of which represent actual customer environments. Installation and configuration are covered in detail since they can be challenging or frustrating at times. We cover the most common installation scenarios and describe the configuration options and our recommendations. The DSS administrator now has many new capabilities and functions not present in OS/2 LAN Server and OS/2 Warp Server. We describe not only the existing functions but also the ne

This redbook provides information about the OS/390 OpenEdition DCE Security Server and its ability to interoperate with RACF; these two elements constitute the OS/390 Security Server. The book explains how to customize and use the DCE Security Server element on the OS/390 platform. It provides information and guidelines on how to develop DCE client/server applications and also provides a few simple application code examples as well as instructions on how to run them. In addition, it explains how DCE application servers can use the new RACF services. One chapter is dedicated to the RACF-DCE interoperation, with detailed instructions and examples on how to set it up. The last chapter addresses some DCE operations and debugging considerations. This redbook will be of value to OS/390 DCE application developers, OS/390 system programmers, and system administrators.

This document is unique in its detailed coverage of AS/400 DCE Base Services/400. It focuses on DCE RPC application development in AS/400 DCE Base Services/400 by providing real example applications that are used to demonstrate DCE functionality and interoperability with OS/400 and DB2/400 data. This book uses the AS/400 system primarily as the server of data and an RS/6000 as the client, but any DCE system (including another AS/400 system) can be used as the client due to the portability of the client code written for this project. This document was written for analysts and programmers. It is not a replacement of the formal manuals that describe AS/400 DCE Base Services/400, but answers many of the questions raised by the system analyst and programmer about how to integrate OSF's DCE into OS/400. Some knowledge of OSF's DCE, OS/400, and AIX is assumed. A diskette that contains all of the sample applications is included.

This redbook provides an implementation of the design for RACF and DCE security interoperation proposed in the International Technical Support Organization publication, GG24-4481-0 MVS/ESA OpenEdition DCE: Application Development Cookbook. The purpose of the redbook is to help expedite the acceptance of MVS/ESA OpenEdition by demonstrating the use of OpenEdition, including both POSIX and DCE. This is a guide for the MVS programmer, with perhaps a strong systems orientation, into the new world of OpenEdition. The redbook shows how DCE security can be used with RACF security in an MVS environment.

This is a guide for the MVS programmer, with perhaps a strong systems orientation, into the new world of OpenEdition. Its purpose is to leverage existing MVS skills into the open systems environment. The assume business orientation is a large mainframe environment with millions of dollars invested in CICS, IMS and other applications.
