In this book, I addressed the DBA tasks in separate sections such as Monitoring, RMAN backup and recovery, Oracle ASM, Data Guard, Database Security, and Version upgrade.
The best method of learning is the practical learning. With this in mind I gave particular importance to the screen shots. Thus, you can do practic by following the book.
Comments and suggestions about the book is very valuable for me. You can send your comments and suggestions to my e-mail address talip_hakan_ozturk@hotmail.com
Hope to get the most from my Oracle books…
