Overview of this book

Business planning is no longer just about defining goals, analyzing critical issues, and then creating strategies. You must aid business integration by linking changed-data events in DB2 databases on Linux, UNIX, and Windows with EAI solutions , message brokers, data transformation tools, and more. Investing in this book will save you many hours of work (and heartache) as it guides you around the many potential pitfalls to a successful conclusion. This book will accompany you throughout your Q replication journey. Compiled from many of author's successful projects, the book will bring you some of the best practices to implement your project smoothly and within time scales. The book has in-depth coverage of Event Publisher, which publishes changed-data events that can run updated data into crucial applications, assisting your business integration processes. Event Publisher also eliminates the hand coding typically required to detect DB2 data changes that are made by operational applications. We start with a brief discussion on what replication is and the Q replication release currently available in the market. We then go on to explore the world of Q replication in more depth. The latter chapters cover all the Q replication components and then talk about the different layers that need to be implemented—the DB2 database layer, the WebSphere MQ layer, and the Q replication layer. We conclude with a chapter on how to troubleshoot a problem. The Appendix (available online) demonstrates the implementation of 13 Q replication scenarios with step-by-step instructions.

Preface

Chapter 6. Administration Tasks

In this chapter, we discuss:

  • Q replication administration tasks, which cover setting up the Q replication environment (as shown in the following diagram)

  • Administration of a running system

These tasks are represented by the various boxes, and will be highlighted as we go through the chapter:

Many of the administration tasks that we need to perform can be achieved using either the Replication Center (only on Linux and Windows) or ASNCLP commands.

The Replication Center can be started either by typing db2rc from a command prompt, or on Windows through the Start menu:

Start | All Programs | IBM DB2 | DB2COPY1 | General Administration Tools | Replication Center

Many of the Replication Center fields have an eclipse button next to them:

If we are unsure as to the correct value for a field, we can press this button and a list of possible values to choose from will be displayed.

The final step of any task that we perform through the Replication Center takes us to the Run Now...
