Summary:  A tried and tested backup and recovery strategy is essential in preventing data loss. A database can encounter any number of problems, including power interruptions, storage media failure, and application crashes. Each of these can result in a database failure and each failure requires a different recovery action. This tutorial introduces the backup and recovery capabilities in IBM® DB2® for Linux®, UNIX® and Windows®. In addition, it presents a step-by-step approach showing how to recover data in various failure scenarios.

About this tutorial

Global support organizations are based on customer service and satisfaction. As such, protecting against failures is a huge challenge for the database administrator. In production or 24 X 7 environments, where databases are mission critical, any data loss is unacceptable. Therefore, it is vital to understand the different data recovery options offered by a database management system (DBMS) as well as have a data recovery plan in place that implements them.

Objectives

This tutorial introduces various DB2 9 recovery options and covers the following topics:

  • Database logging
  • How to change the database logging mode
  • Best practices to keep database data safe
  • How to recover an entire database after a failure
  • How to recover when a table space container gets dropped or corrupted
  • How to recover a table that is dropped by accident
  • How to recover to a specific point-in-time
