IBM Communication Controller Migration Guide

IBM communication controllers have reliably carried the bulk of the world's business traffic for more than 30 years. Over the years, IBM controllers have been enhanced to the point that the functional capabilities of the current products, the 3745 Communication Controller and the 3746 Nways Multiprotocol Controller , surpass the capabilities of any other data networking equipment ever developed. Beyond the SNA architecture PU Type 4, beyond APPN, even beyond IP routing, these controllers support an extraordinary set of functions and protocols. Because of their long history and their functional richness, IBM controllers continue to play a critical role in the networks of most of the largest companies in the world. Over the past decade, however, focus has shifted from SNA networks and applications to TCP/IP and Internet technologies. In some cases, SNA application traffic now runs over IP-based networks using technologies such as TN3270 and Data Link Switching (DLSw). In other cases, applications have been changed, or business processes reengineered, using TCP/IP rather than SNA. Consequently, for some organizations, the network traffic that traverses IBM communication controllers has declined to the point where it is in the organization’s best interest to find functional alternatives for the remaining uses of their controllers so they can consolidate and possibly eliminate controllers from their environments. This IBM Redbooks publication provides you with a starting point to help in your efforts to optimize your communication controller environment, whether simply consolidating them or migrating from them altogether. We discuss alternative means to provide the communication controller functions that you use or ways to eliminate the need for those functions outright. Where multiple options exist, we discuss the relative advantages and disadvantages of each.

DB2 UDB for z/OS: Design Guidelines for High Performance and Availability

Conducting business via the Web and remaining open for business 24 hours a day, seven days a week is now commonplace. Customers come in with unexpected workloads through the Web and operate in a self-service fashion with mostly context-sensitive metadata to guide them. The strong requirement is availability. However, even with new Web applications, most of the core business systems considerations still apply, and performance is critical. Technology has been accelerating for mainframe systems. They had become adept at providing business resiliency accommodating strategic software that has been around for the last several decades such as IMS™ , DB2® , and CICS® , and they have also become a host for developing and running Web applications built in Java™ accommodating the latest business requirements. Businesses need to leverage, extend and integrate the strategic assets which represent multi-year investments to support leading edge technology. DB2 for z/OS® has come a long way and provides facilities to exploit the latest hardware and software technologies, accommodating a majority of user requirements. However, special considerations are required to build high performance applications. If you want to achieve high performance or high availability, you must use the design, programming, and operational techniques applicable to DB2.

Business Process Execution Language for Web Services - Second Edition

Key Features Architecture, syntax, development and composition of Business Processes and Services using BPEL Advanced BPEL features such as compensation, concurrency, links, scopes, events, dynamic partner links, and correlations Oracle BPEL Process Manager and BPEL Designer Microsoft BizTalk Server as a BPEL server Book Description Web services provide the basic technical platform required for application interoperability. They do not, however, provide higher level control, such as which web services need to be invoked, which operations should be called and in what sequence. Nor do they provide ways to describe the semantics of interfaces, the workflows, or e-business processes. BPEL is the missing link to assemble and integrate web services into a real business process BPEL4WS standardizes process automation between web services. This applies both within the enterprise, where BPEL4WS is used to integrate previously isolated systems, and between enterprises, where BPEL4WS enables easier and more effective integration with business partners. In providing a standard descriptive structure BPEL4WS enables enterprises to define their business processes during the design phase. Wider business benefits can flow from this through business process optimization, reengineering, and the selection of most appropriate processes . Supported by major vendors - including BEA, Hewlett-Packard, IBM, Microsoft, Novell, Oracle, SAP, Sun, and others - BPEL4WS is becoming the accepted standard for business process management. This book provides detailed coverage of BPEL4WS, its syntax, and where, and how, it is used. It begins with an overview of web services, showing both the foundation of, and need for, BPEL. The web services orchestration stack is explained, including standards such as WS-Security, WS-Coordination, WS-Transaction, WS-Addressing, and others. The BPEL language itself is explained in detail, with Code snippets and complete examples illustrating both its syntax and typical construction. Having covered BPEL itself, the book then goes on to show BPEL is used in context. by providing an overview of major BPEL4WS servers. It covers the Oracle BPEL Process Manager and Microsoft BizTalk Server 2004 in detail, and shows how to write BPEL4WS solutions using these servers. What you will learn Chapter 1 provides a detailed introduction to BPEL and Service Oriented Architecture (SOA). It discusses business processes and their automation, explains the role of BPEL, web services, and Enterprise Service Buses (ESB) in SOA, provides insight into business process composition with BPEL, explains the most important features, compares BPEL to other specifications, provides an overview of BPEL servers, and discusses the future of BPEL. Chapter 2 provides a detailed introduction to the Web Services Technology Stack. It discusses the important standards and specifications for using BPEL and implementing SOA with web services, such as WS-Security, WS-Addressing, WS-Coordination, WS-AtomicTransaction, WS-BusinessActivity, WS-Reliable Messaging, etc. Chapter 3 discusses the composition of web services with BPEL. The chapter introduces the core concepts of BPEL and explains how to define synchronous and asynchronous business processes with BPEL. The reader gets familiar with BPEL process structure, partner links, sequential and parallel service invocation, variables, conditions, etc. Chapter 4 goes deeper into the BPEL specification and covers advanced features for modeling complex business processes. Advanced activities, scopes, serialization, fault handing, compensations, event handling, correlation sets, concurrent activities and links, process lifecycle, and dynamic partner links are covered in detail. Chapter 5 explains how to use the Oracle BPEL Process Manager for deploying and executing business processes defined in BPEL. It describes the server architecture, tools, features, and common approaches for managing and debugging BPEL processes. The chapter also looks at graphical development of BPEL processes using Oracle BPEL Designer for JDeveloper and for Eclipse. Chapter 6 takes a detailed look at the advanced features of the Oracle BPEL Process Manager including extension functions, dynamic parallel flows, Web Services Invocation Framework, Java embedding, Notification service, Workflow service, Identity service, and Oracle BPEL Server APIs. Chapter 7 discusses MS BizTalk Server 2004 and its support for BPEL. It explains how to develop business processes in BizTalk and export them to BPEL. It also explains how to import BPEL processes into BizTalk and how to use the Orchestration Designer tool to define processes graphically, and compares BizTalk and BPEL constructs. Appendix A provides a syntax reference for BPEL version 1.1. The appendix covers standard BPEL activities and elements, functions, attributes, and faults. Who this book is for This book is aimed at architects and developers in the design, implementation, and integration phases of advanced information systems and e-business solutions, developing business processes and dealing with the issues of composition, orchestration, transactions, coordination, and security.

Learning SQL

SQL (Structured Query Language) is a standard programming language for generating, manipulating, and retrieving information from a relational database. If you're working with a relational database--whether you're writing applications, performing administrative tasks, or generating reports--you need to know how to interact with your data. Even if you are using a tool that generates SQL for you, such as a reporting tool, there may still be cases where you need to bypass the automatic generation feature and write your own SQL statements. To help you attain this fundamental SQL knowledge, look to Learning SQL, an introductory guide to SQL, designed primarily for developers just cutting their teeth on the language. Learning SQL moves you quickly through the basics and then on to some of the more commonly used advanced features. Among the topics discussed: The history of the computerized database SQL Data Statements--those used to create, manipulate, and retrieve data stored in your database; example statements include select, update, insert, and delete SQL Schema Statements--those used to create database objects, such as tables, indexes, and constraints How data sets can interact with queries The importance of subqueries Data conversion and manipulation via SQL's built-in functions How conditional logic can be used in Data StatementsBest of all, Learning SQL talks to you in a real-world manner, discussing various platform differences that you're likely to encounter and offering a series of chapter exercises that walk you through the learning process. Whenever possible, the book sticks to the features included in the ANSI SQL standards. This means you'll be able to apply what you learn to any of several different databases; the book covers MySQL, Microsoft SQL Server, and Oracle Database, but the features and syntax should apply just as well (perhaps with some tweaking) to IBM DB2, Sybase Adaptive Server, and PostgreSQL. Put the power and flexibility of SQL to work. With Learning SQL you can master this important skill and know that the SQL statements you write are indeed correct.
