Congratulations to Mr. Sabdar and Mr. Ben Prusinski

Many congratulations to my fellow Oracle ACEs,  Mr. Syed Sabdar Hussain (my brother) and Mr. Ben Prusinski (friend and co-author of my upcoming Oracle 11g RAC book) whose short interview published in Oracle Magazine's (March/April 2010 edition) peer-to-peer section.

Book Review: Oracle 11g Streams Implementer's Guide

I know its been more than a month I had promised to write a review on this book at my blog. The fact is that I was occupied by too many production critical  issues that doesn't allow me to concentrate on any thing. Nevertheless, I took sometime time to fulfill my promise and here is my chapter-by-chapter review:

Chapter 1: All the Pieces: The Parts of an Oracle 11g Streams Environment

I strongly believe in that the basic understanding of any architecture is the most important factor for  the successful implementation.This is one of the most vital chapter of the book where it discussed thoroughly setting about various types of streams environments, such as, single database, bi-directional, master-to-master plus it also talked about the their architecture and some internal mechanics.  Some very important key factors that are involved in the implementation phase, like, the importance of network design involved between the sites, important initialization parameters that are needed to tweak for the good performance also have been discussed in this chapter.

Conclusion: The chapter contains a thorough explanation about the streams setup and architecture.

Chapter 2: Plot Your Course: Design consideration

This chapter provides the guidelines on the details to be considered during the streams design phase. It talks about the business requirement of your data, talks about the strategies on 'Who, What, when, Where, Why and How' terms. The other important key factor involved in the implementation is about the resource requirements on the server and the additional cost involved with the implementation.

Conclusion: The chapter provides the insights needed to design and the strategies, server resources and other important factors required during the stream implementation phase.

Chapter 3 : Prepare the Rafts and Secure Your Gear: The pre-work before configuring Oracle 11g Streams

This chapter talks about the the pre configuration work that is needed  for streams implementation. Where it discussed the importance of having reliable and stable network setup, important database parameters, setting up supplemental logging on the database, required Streams Administrator user and its permissions. It also suggest to have a separate tablespace for the LogMiner to avoid using SYSTEM or SYSAUX tablespaces are being used.

Conclusion: Over all, its a nice chapter discussing the pre work that is required for the streams implementation.

Chapter 4: Single-Source Configuration

This chapter demonstrated how to setup a single-source (uni-directional) streamed environment utilizing one of the convenient methods, Enterprise Manager (DB Console) wizards. Subsequently discussed the code which run behind the screen step-by-step. It also demonstrated how to schedule the jobs.

Conclusion: The first hands-on chapter for the readers.

Chapter 5: N-Way Replication

This chapter neatly explains about building N-Way replication(between multiple sources) topic, such as, pre-planning, techniques,avoiding conflicts, setup and etc.

Conclusion: It contains some very good examples which is can be very handy.

Chapter 6: Get Fancy with Streams Advanced Configurations

As the heading states, this chapter explained some of the advanced configuration features of Streams, such as, synchronizing capture, tag, rules, heterogeneous replication (basics) and etc. I particularly liked all the examples shows on its way of explanation about the advanced features.

Conclusion: A bit lengthy chapter, but, contains very useful set of examples.

Chapter 7 : Document What You Have and How It Is Working

I must totally agree with the authors on this point (preparing documents). This chapter started with a strong question, 'concern of loosing a key member of any team?'. Correct me if I am wrong saying if there is any boring part for the technical guys is the documentation part, don't you agree with my guys? The goal of this chapter is to use some of the Oracle packages to learn how to document, set up and monitor Streams environment.

Chapter 8: Dealing with the Ever Constant Tides of Change

This chapter has discussed the techniques for identifying and troubleshooting issues with Streams when there is a change or even no changes made. There is an in-depth explanation about the approach while doing any changes to the Stream environment, whether the change directly reflects the Streams environment or may impact from the outside of the environment.

Conclusion: A good proactive chapter.

Chapter 9: Appendix and Glossary
This chapter discussed various other options, such as Streams on Oracle RAC, Oracle GolddenGate and alternative method of monitoring streams.

Overall Impression:

I strongly recommend this book to fellow Oracle DBAs who are planning to setup Streams Environment or also who already implemented the streams and wanted to monitor their environment. I thoroughly enjoyed and learned many practical implementation details and insights in this book.  Finally, I thank Shernell at Packt Publications for providing me an opportunity to read and write a review for this book.
