7.2.1 Report utility<br />
The list command queries the recovery c<strong>at</strong>alog, and its primary purpose is<br />
to determine which backup copies are available for use when recovery is<br />
needed. You require this list to loc<strong>at</strong>e and publish inform<strong>at</strong>ion, such as a list<br />
of backup sets containing:<br />
A backup of a specific d<strong>at</strong>a file<br />
Backups for a specific tablespace<br />
Backups for the whole d<strong>at</strong>abase<br />
The crosscheck command queries the recovery c<strong>at</strong>alog and verifies whether<br />
backup sets marked available or expired are available.<br />
For objects stored on disk (type disk ): The command determines whether<br />
the header of the backup piece is valid.<br />
For TSM objects (type sbt_tape ): The command simply checks th<strong>at</strong> the<br />
backups exist.<br />
You can use this utility regularly to verify if your backup is still available.<br />
Following are examples of how you can use these utilities to perform<br />

to the <strong>Oracle</strong>8i Recovery Manager User’s Guide and Reference, A76990-01.<br />
