Oracle Backup and Recovery

“The developer who has failed in design can be forgiven, but the administrator who has failed in backup and recovery cannot be forgiven.” 

Just as the above indicates, backup and recovery requires a lot of experiences and knowledge along with discretion. However, it would be too risky to learn the backup and recovery by practicing it, because a simple failure in the backup and recovery will generate tremendous loss. That is why you have to study how to respond and keep a good book at hand so that you can get help from the book whenever you want. In this sense, I can guarantee that this book will serve as a strong anchor when you are in trouble.  


One of the characteristics of the book is that it presents various types of errors and failures you may encounter at the field. It analyzes error and failure causes from the different perspectives, and explains how to actually do the recovery, particularly focusing on the practical work. 


It also contains many case-by-case scenarios that are easy to find, so you can get the solutions you need without any difficulty. For example, when you start up the Oracle you may face “ORA-00205: error in identifying control file, check alert log for more info” message and see the Oracle server doesn’t start. In this case, you can refer to the case 1 in the chapter 5 to immediately know the solution. If you drop a table by mistake, you may refer to the chapter 9 in order to recover the table without stopping the server. If you want to respond to the errors and failures that happen in a RAC environment, you can go to the chapter 12 and refer to the cases of various error types. Simply speaking, this book classifies all the errors and failures based on their types, and explains their causes and the responses to them. 


Sometimes you may successfully do the recovery, not knowing how the recovery is done. This is because you simply memorize how to respond. If you understand the principles of the recovery, going beyond simple memorization, you can always respond to a more complex and difficult situation. Understanding the principles will help you put your knowledge to practical use. Various examples and easy explanations on the principles of the book will surely enhance your ability to apply your knowledge. 


Make sure you keep this book in order to become the professional engineer who never fails in backup and recovery!
