Database Reference
In-Depth Information
The RMAN recovery catalog is an optional component that
you can use with RMAN. The recovery catalog provides an
additional place to store RMAN related metadata, such as when
backups were taken and where they were stored. In this chapter, we will review the recovery
catalog so you will be prepared to answer recovery catalog OCP exam questions. This chapter
will contain the information that you need to pass the Oracle OCP exam with respect to the
RMAN recovery catalog.
So, let's get on with learning about the recovery catalog!

Introducing the Recovery Catalog
The
RMAN recovery catalog
is a schema that sits in an Oracle database. This schema is
designed to store RMAN-related information. The information stored in the recovery cata-
log is in large part just like that stored in the control file. Since most RMAN information is
stored in the control file of a database, the recovery catalog serves as a backup repository for
RMAN information.
Using the recovery catalog has some clear benefits that need to be carefully considered.
The first is that it acts as a single location to store all your RMAN backup-related
information.
■
The recovery catalog can store backup-related information for many databases.
■
The views of the recovery catalog are well documented, and so you can build reports
from those views that will help you to understand the current status of your database
backups.
