Oracle Backup and recovery is one of the essential duties of Oracle DBA oracle dba interview questions for experienced professionals : check out awesome oracle dba interview questions and answers to succeed in any oracle database interviews. To generate a list of copies and backups restricted by object or other conditions:.

Every time you reset the online redo logs of a target database, you create a new incarnation of the database. The incarnation is distinguished by its incarnation key. To gain more detailed information from the RMAN repository, generate a report.

The information that you obtain from reports can be extremely important for your backup and recovery strategy. The DAYS parameter indicates that recovery must begin by using logs more than integer days old. Note that RMAN prompts you for confirmation before actually deleting the files. Specify FORCE to delete the files and remove their repository records regardless of whether the files exist.

If the employee table is located in datafile 3, then the REPORT command can flag backups of this datafile as unrecoverable. For example, enter:. If you use a recovery catalog, then you also generate historical reports of the database schema at a past time. You do not need a recovery catalog, however, to report the current schema.

To report the database schema at a specified point in time:. If you use a recovery catalog, then you can use the atClause to specify a past time, SCN, or log sequence number:. This type of information is useful for incomplete recovery because you can determine the schema of the database for the time to which you want to recover. These settings are persistent in the sense of being configured for use with any RMAN session. By using the SHOW command, you can perform the queries discussed in the following sections:.

For example, enter the following:. Note that the output is displayed so that you can paste it into a script and run it as an RMAN command file; hence, you can easily change your entire configuration.

You can even run the script on a different target database. The DISK device type is preconfigured. Note that you cannot disable the default device type: it is always either DISK default setting or sbt. To show the tablespaces excluded from whole database backups:.

For example, if the value is 3 , RMAN produces a total of three identical copies of each backup piece in a backup set. The size of a backup set is measured in the total bytes of the included backup pieces.

If desired, you can save the output to an RMAN log file. Note that you must connect to the target database that you connected to when you created the script. To list the scripts for the current incarnation of a target database:. Oracle9i Recovery Manager Reference for reference information about the recovery catalog views. The recovery catalog views are not normalized, but are optimized for RMAN usage rather than user queries.

RMAN obtains backup and recovery information from the target database control file and stores it in the catalog tables. In general, the recovery catalog views are not as user-friendly as the RMAN reporting commands. If you have 10 different target databases registered in the same recovery catalog, then the catalog views show the information for all incarnations of all databases registered in the catalog.

You often have to perform joins among the views to distinguish the specific incarnation of the target database that you are interested in. Most of the catalog views have a corresponding dynamic performance view in the database server. The primary difference between the catalog and server views is that each catalog view contains information about all the databases registered in the catalog, whereas the server view contains information only about itself. The two types of views often use different primary keys to uniquely identify rows.

When querying information about a specific incarnation of a target database, you should use these columns to specify the database. Then, you can perform joins with most of the other catalog views to obtain the desired information. The corresponding catalog view uses a derived value as its primary keys and stores this value in a single column.

The DBID, which is a unique system-defined number given to every Oracle database, is what distinguishes one target database from another target database in the RMAN metadata. Assume that you want to obtain information about one of the target databases registered in the recovery catalog. Use the LIST command to query the contents of the recovery catalog or the target database control file if no recovery catalog is used.

You can use several different parameters to qualify lists. For example, if you only need to be able to recover the database to a point within the last two weeks, then issue this command:.
