If you're a working Oracle DBA, here's the Oracle backup/recovery reference you've been searching for--simple, straightforward, and incredibly easy to use! This book covers every type of Oracle backup, every major recovery scenario, and every technique and tool--including export/import, Rman, flash backup, mirror splitting, snapshotting, and more. Keep it by your desk, near your server...wherever you need fast, reliable answers right this minute!

The Oracle database is a complex and ever changing product that has grown increasingly complex and powerful over the years. One of the most important tasks faced every day by the Oracle DBA is backing up and recovering the Oracle database and protecting the data it stores. As the size and complexity of the database has grown, so too has the capability and complexity of the backup and recovery tools that support it. When we first started working with Oracle databases, the only tools available were export and import. And using them on a space constrained system in the days when hard drives were expensive could be an interesting exercise. Now Oracle supports not only export and import, but also the Recovery Manager (RMAN) and new for Oracle 10 g, the Oracle Data Pump. The Oracle Data Pump is a lot like a server side version of the old export/import, but the commands are often different.
This book is not an attempt to teach the new Database Administrator (DBA) everything she or he needs to know about how to backup and recover an Oracle database. That would be an interesting book challenge, but not the one we wanted to tackle. Instead, we wrote the book we've both been wishing we had, but couldn't find anywhere. A simple reference to the Oracle backup and recovery tools that are available, and some of the critical tables and views that the practicing Oracle DBA needs every day. This is a purely syntax reference, a quick way to get a reminder of what options a command takes and the exact syntax required. Most Oracle DBAs spend probably 90% of their time doing less than 5% of the tasks possible with an Oracle database. They neither need nor want a book to givethem the syntax for those commands they use every day. But when you're trying to recover a critical table that someone dropped, or trying to figure the easiest way to make a copy of subset of a database for the sales team to run locally on their laptops, having a quick reference to the syntax and options for the Oracle backup and recovery tools can be a real time saver. And that's the purpose and intent of this book--to give the working DBA a quick, little, book that they can keep on their desktop or next to server where they can quickly look up the syntax for the command they need, or find the right name for the view they know exists, but haven't had to use since the last time there was a problem. As Oracle has grown from our first days with Oracle 6 to the complexity and power of Oracle 10 g, the number of options for backup and recovery has grown enormously. If you're like us, you know there are new options and ways to do things, but often need a quick reminder of the syntax or options available. We hope you'll find this book a useful tool for that.
This book is divided up into four chapters:
Chapter 1 - covers the concepts of backup and recovery and how the Oracle tools work to support those concepts.
Chapter 2 - is a complete reference to the Export, Import and Oracle Data Pump utilities of Oracle 10 g , showing the syntax and options for each of them, in alphabetical order. We have used standard "railroad" syntax diagrams to make it easy to follow the options and syntax required.
Chapter 3 - describes the RMAN procedures used to perform the every day tasks, and some specialized ones, that the Oracle DBA needs. The procedures and commands required to configure RMAN, including setting up a Recovery Catalog, are covered, along with examples of common backup and recovery tasks. Examples are provided.
Chapter 4 - is a complete reference to the RMAN of Oracle 10 g, showing the syntax and options for each command, in alphabetical order. We have used standard "railroad" syntax diagrams to make it easy to follow the options and syntax required. Also covered are the changes to Oracle's RMAN, with a list of deprecated commands, and a complete listing of the RMAN catalog views and the corresponding V$ views.
A note on the syntax diagrams used in Chapter 4. Certain subclauses show up across a wide range of commands with no change in the syntax or options they support. In order to keep the diagrams as simple as possible, we have grouped those clauses at the end of the chapter under "Subclauses and Common." Within each command, we have broken out the syntax for the less common clauses immediately following the main command. This enables a simpler and more readable diagram while providing full information. We have underlined the names of subordinate clauses in the diagrams to make it clear that you need to break out of the main diagram for the syntax to that clause.

If you are an Oracle database administrator and you have a background as a unix or Microsoft sysadmin, then you might wonder why there is a need for an ENTIRE book on backup of Oracle's database. It is not that you doubt the need for a backup. But a whole book? In unix, you do a 'man' on the backup command and you are shown a few screens of options. Likewise for restoring. Under Microsoft, a similar situation prevails. But unix and Microsoft are general purpose operating systems. An operating system is basically about file manipulation. In essence, a file is the atomic unit to the OS. So the backup and restore options are limited to the richness of this information. But Oracle's database is a specialised and elaborate 'operating system'. The data is constrained and structured far more than files in a real OS. A backup can take advantage of this by offering hugely more options to you; a far more expressive set of commands to do a fine grained backup of fairly arbitrary subsets of the data. And of course, also with the restore. This increased power comes at a price. Remembering all those darned options, especially the obscure, rarely invoked ones. Hence this book. Its value is strictly as a memory aid. You have to already understand what those options do, from Oracle's official documentation. The book uses a common flow chart style graph for the options, for easier use.
