Overview of this book

At times, DBAs support 100s of databases at work. In such scenarios, using a command-line tool like putty adds to the difficulty, while SQL Developer makes the life of a developer, DBA, or DB architect easier by providing a graphical user interface equipped with features that can bolster and enhance the user experience and boost efficiency. Features such as DBA panel, Reports, Data Modeler, and Data Miner are just a few examples of its rich features, and its support for APEX, REST Services, timesten, and third-party database drivers demonstrate its extensibility. You may be a newbie to databases or a seasoned database expert, either way this book will help you understand the database structure and the different types of objects that organize enterprise data in an efficient manner. This book introduces the features of the SQL Developer 4.1 tool in an incremental fashion, starting with installing them, making the database connections, and using the different panels. By sequentially walking through the steps in each chapter, you will quickly master SQL Developer 4.1.

Restore points


Oracle Flashback database and restore points enable us to rewind the database back in time to correct any problems caused by logical data corruption or user errors, and it doesn't require any restoration of backup. There are two types of restoration points, which are as follows:

  1. Normal Restore Point: Assigns a restore point name to an SCN or specific point in time. The control file stores the name of the restore point and the SCN.

  2. Guaranteed Restore Point: Is a normal restore point, but additionally serves as an alias for an SCN in recovery operation. The only difference is that the guaranteed restore points never age out of the control file and must be explicitly dropped.

    To create a restore point or view existing restore points, click on Restore Points.

  3. View Database Feature Usage: Selecting this option shows us the list of all available database features and the detected count of usages and versions of all those features.
