Introduction
Recovery Manager is Oracle’s utility to manage the backup, and more importantly the recovery, of the database. It eliminates operational complexity while providing superior performance and availability of the database. Recovery Manager debuted with Oracle8 to provide DBAs an integrated backup and recovery solution.
Recovery Manager determines the most efficient method of executing the requested backup, restore, or recovery operation and then executes these operations in concert with the Oracle database server. Recovery Manager and the server automatically identify modifications to the structure of the database and dynamically adjust the required operation to adapt to the changes.
This note applies to the following versions of these products:
Oracle Server - Enterprise Edition - Version: 10.2.0.1 to 10.2.0.x
Oracle Server - Enterprise Edition - Version: 11.1.0.6 to 11.1.0.x

Getting started with RMAN
The articles in this section give you a overview of the oracle utility RMAN,the new features of RMAN in Oracle 11 release 1,2 and FAQ on RMAN.

Rman compatibility
Flash Recovery Area
The flash recovery area is an Oracle-managed directory, file system, or Automatic Storage Management disk group that provides a centralized disk location for backup and recovery files. All the files you need to completely recover a database from a media failure are part of the Flash Recovery Area. Oracle creates archived logs and flashback logs in the flash recovery area. RMAN can store its backup sets and image copies in the flash recovery area, and it uses it when restoring files during media recovery. The flash recovery area also acts as a disk cache for tape.
The articles mentioned in the following section help you in understanding the concepts and working of flash recovery area,Rman integration with the flash recovery area,troubleshooting flash recovery area issues

Configuring the Environment for RMAN Backups
To simplify ongoing use of RMAN, you can set a number of persistent configuration settings for each target database. These settings control many aspects of RMAN behavior. For example, you can configure the backup retention policy, default destinations for backups, default backup device type, and so on. You can use the SHOW and CONFIGURE commands to view and change RMAN configurations.
The articles mentioned in the following section help you in configuring the rman persistent configurations,understanding their behaviour and troubleshooting them.

Recovery Catalog for Rman backups.
A recovery catalog is a set of tables and views that Recovery Manager (RMAN) uses to store metadata (information about a database structure, archived redo logs, backup sets, and data file copies) about a target database (database that RMAN backups or restores). RMAN uses this metadata to conduct its backup, recovery, and maintenance operations. Recovery catalog is optional, i.e., if a recovery catalog is not created, RMAN uses the target database’s control file to store the metadata about the target database. Although RMAN can conduct all major backup and recovery operations by using the control file, some RMAN commands work only if a recovery catalog exists.
The articles in the following section describe the configuration,managment of recovery catalog and some of the known issues related to recovery catalog.

RMAN and Media managers
Oracle designed an architecture that allows RMAN to manage the process of database backup and recovery, yet integrate with industry-leading tape storage management subsystems. The interface between Rman and media management vendor products is keyed on an Oracle design specification. This specification allows Oracle RMAN to use third party media management software to back-up to and restore from tape.
Many organizations rely on Oracle to provide solutions for very large or highly distributed mission critical systems. In addition to needing databases capable of handling large amounts of data and complex queries, these organizations also need robust backup and recovery technology. Recovery of data quickly and reliably is paramount should some aspect of the system fail. To address these needs, Oracle has created the Backup Solutions Program (BSP), a cooperative program designed to facilitate tighter integration between Oracle's backup products and those of third-party media management vendors. Together, Oracle and media management vendors provide robust easy-to-use database backup and recovery solutions to customers with high-end requirements.
The link to access the information regarding backup solutions program is:
"Under the BSP, vendors are committed to integrating Recovery Manager (RMAN) with their media management software packages and provide first line technical support for the integrated backup and recovery solutions for Oracle RDBMS."
So any issues related to the media manager functionality or configuration has to be addressed only by the vendors and not by Oracle.
Below are a few articles which help you in understanding the most common issues with rman backups to tape, environment variable used for backups to tape and procedure to check if the media manager installation has been done properly.

Rman and Dataguard
Data Guard and RMAN were both designed with the Oracle database architecture in mind. Together, they offer the most reliable and tightly integrated solution to achieve superior levels of Oracle database availability supporting your mission critical applications. Data Guard and RMAN are both fully supported features of the Oracle Database Enterprise Edition (RMAN is also provided with Oracle Database Standard Edition).Here are a few articles that help you in effectively using rman with dataguard and some of the known rman issues with dataguard.
