A lot more to dB2 than just standard SQL 4 out of 5 stars.
5 of 7 people found this review helpful.
If you have been a sysadmin and are familiar with the concepts of full and incremental backups of an operating system, then this book's descriptions of dB2's abilities in this field are very impressive. dB2 offers far more fine grained control/resolution over the backing up of its data. Like the means of having circular or archival logging. So if you are just starting out as a dB2 administrator, you have quite a bit more to learn, just in this field.On a tangential note: Suppose you have your own non-database application, with its own native data file format, and you want to regularly save its activities. Try looking at the ideas in this book for how dB2 does its duties. You might be able to abstract out the ideas and reinstantiate them in your context. The book presents the right level of discussion for this. One caveat is that IBM has a portfolio of patents around dB2, and I do not know the extent that you might be able to implement some of the book's ideas without infringing on the patents.
Of course, there is far more to dB2 than backups. The book goes into other topics. Like how to define and run a standby database, by sending log files to it in a systematic fashion. Or, how to make a "split mirror" warm standby.
My overall impression is that IBM has engineered a vast amount of backup and availability into dB2, to handle almost any level of transaction load. There is a lot more to dB2 than just being able to handle standard SQL.
Editorial Review:
This book clearly addresses all aspects of minimizing system failure. From basic backup and recovery concepts all the way up to advanced recovery tuning and configurations for High Availability and Disaster Recovery, this book has unique coverage not found elsewhere. The day-to-day responsibilities of the reader would range from architecting, planning and configuring highly available enterprise database systems to tuning and monitoring existing systems to maintain maximum availability. After reading this book, database administrators will be able to setup, tune and monitor highly available DB2 systems and have an understanding of how to choose the availability option that best meets their needs.
