I dealt with the Flashback Table feature in 8. I discuss the Flashback Database and the Flashback Drop features later in this chapter. In addition, Oracle Database 11g has introduced a brand-new Flashback feature named Flashback Transaction Backout, which I discuss in this chapter as well. Media recovery: Media recovery is probably the most drastic way of fixing a persistent failure. If you lose a datafile, for example, you must restore a copy of that datafile from the backups. However, restoring the backups only gets you so far, since the backups are from a previous point in time. Depending on the frequency of your backups, they could be several days or even weeks old. To update the restored file, then, you must next recover the database by updating with the archived redo logs and online redo logs, which is generally what is known as media recovery. You can use several types of media recovery, as explained here: Block media recovery Datafile media recovery Complete recovery Point-in-time recovery

The three major components of ASM are the ASM instance, ASM disk groups, and ASM files Let s look briefly at these important ASM components The ASM instance is a special Oracle instance it does not have its own data files like a regular Oracle database does A single ASM instance on a server can manage the ASM file systems for all the Oracle databases on that server The ASM instance looks after disk groups and gives the database access to the ASM files The database makes the initial contact with the ASM instance to get information on the data files, but it accesses those files directly.

In this chapter, I discuss the three major methods of repairing persistent failures in the database. However, before we start discussing the recovery alternatives, you first need to become familiar with the basic concepts of Oracle database recovery.

The ASM instance must be running for an Oracle database to use the ASM file system, and the ASM instance can t be shut down while the other Oracle databases using ASM file systems are still running, since those databases will crash without the ASM instance ASM disk groups are somewhat analogous to logical volumes created by a Logical Volume Manager Unlike the usual Oracle database files, you don t access ASM files directly Disks in an ASM context are rather loosely defined and can include a partition of a disk spindle or the entire disk spindle itself This depends on how the storage system represents the logical unit number (LUN) to the operating system Any LUN or a disk represented to the operating system is called a disk Since each operating system could have a different disk-naming system, check your disk-naming system.

You can broadly divide Oracle database recoveries into crash and instance recoveries on one hand and media recoveries on the other. Let s clarify the differences between these two types of recoveries.
