DCOM Explained by ROSEMARY ROCK-EVANS

DCOM Explained describes what services DCOM provides, both development and runtime. Thus the aim of the book is not to teach how to program using DCOM, but to explain what DCOM does so readers will become better able to use it more effectively, understand the options available when using DCOM, and understand the types of applications that can be built by using DCOM.

This book describes:
· what each of the services mean, including load balancing, security, guaranteed delivery, deferred delivery, broadcasting and multi-casting, and session handling.
· what the service aims to do, such as saving time and effort or providing a secure, resilient, reliable, high performance network
· how the service could be provided, and what other solutions exist for achieving the same end
· how Microsoft has tackled the problem

Provides a complete, easy to understand, and compact picture of all the services of DCOM
Written from a designer or manager's point of view
Compares DCOM with other middleware

The Waite Group's COM/DCOM Primer Plus

Very good book for DCOM beginners. This book does a very good job of presenting DCOM for the developer that isn't quite ready to dive into DCOM head first. I was honoured to work with such a great crew of writers. If you're an advanced DCOM user, then place your order now for the upcoming DCOM Unleashed book by MCP.

Synopsis
Microsoft's Component Object Model (COM) is a specification for developing software components that can be dynamically interchanged. DCOM is a technology that enables software components to communicate directly with each other across network and the Internet.

Mastering COM and COM+

COM (Component Object Model) is Microsoft's specification for building distributed applications that work across networks and the Internet. It is a highly complex and mysterious topic, which ties in to everything Microsoft is doing with Windows. In this book aimed at experienced programmers, Ash Rofail unlocks the secrets of programming COM, writing in the classic Mastering style. This is no theoretical treatise but a practical exploration of how to do real things with COM, including creating COM objects, working with the Registry, reusing components, and getting the most out of ActiveX controls. Includes coverage of DCOM and COM+, Microsoft's latest version of the standard for Windows 2000.

Understanding COM+

ISBN: 0735606668
Author: David S. Platt
Publisher: Microsoft Pr
Edition:
Language: English
Paperback: 235 pages
Summary:Written for the IS manager or developer, Understanding COM+ explains the details of the emerging Windows 2000 COM+ standard and the real advantages it provides for enterprise computing. Clearly written and illustrated with easy-to-understand diagrams, this title succeeds in explaining the fairly difficult "plumbing" of COM+ and its impact for the future of businesses running on the Microsoft platform.Though it provides a good deal of technical detail, the standout feature of this book is its focus on real-world business problems in the enterprise and the solutions offered by COM+. Any IS manager or developer will be able to understand concepts like transactions, resource management, events, and asynchronous communications through the author's carefully rendered diagrams and business scenarios. There's not much actual code here, but the author does suggest techniques for designing components to take advantage of COM+.Standout material includes a full discussion of the built-in support for transactions in COM+ and a new feature that has real potential for better performance for today's Web sites: In-Memory Databases (IMDBs). (With IMDBs, instead of optimizing code, administrators can just add more RAM to the server for a real performance boost.)As the author notes, COM+ builds on the success of COM on the Microsoft platform. For any IS manager or programmer working on Windows, Understanding COM+ delivers a useful introduction to what's best in the new COM+ on Windows 2000. --Richard DraganTopics covered: Enterprise applications and COM+ overview, COM+ architecture and infrastructure, interception, COM+ components and catalogs, context and transactions, security, threading models and synchronization, resource management, Just-In-Time (JIT) object activation, object pooling, queued components (QC) and asynchronous communications, queue moniker, COM+ events (publishers and subscribers, COM+ In-Memory Databases [IMDBs], and load balancing).
