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 7. Monitoring and Reporting

This is the last chapter of the book. In this chapter, we discuss:

  • How we can monitor our Q replication setup

  • The tools available to report on the setup, for documentation, and trouble-shooting purposes

We will start by looking at what we need to monitor at the three different layers (database layer, WebSphere MQ layer, and Q replication layer). We then go on to discuss the Replication Alert Monitor and other tools to monitor the environment. The chapter concludes with some what if scenarios, some comments on Q replication performance, and a discussion on some common error messages.

The answer to the question What do we need to monitor is almost the same as the answer to the question How long is a piece of string. The simple answer is it depends—which we are sure, will not come as a big surprise to you. What we hope to do in the following sections is—give you a manageable list of items to monitor to cover most situations.
