# 2.1 Summary of RMAN Commands

Table 2-1 provides a functional summary of RMAN commands that you can execute at the RMAN prompt, within a `RUN` command, or both. All commands from previous RMAN releases work with the current release.

For command line options for the RMAN client, refer to "cmdLine".

Table 2-1 Recovery Manager Commands

Command | Purpose
--- | ---
"@" | Run a command file.
"@@" | Run a command file in the same directory as another command file that is currently running. The `@@` command differs from the `@` command only when run from within a command file.
"ALLOCATE CHANNEL" | Establish a channel, which is a connection between RMAN and a database instance.
"ALLOCATE CHANNEL FOR MAINTENANCE" | Allocate a channel in preparation for issuing maintenance commands such as DELETE.
"allocOperandList" | A subclause that specifies channel control options such as `PARMS` and `FORMAT`.
"ALTER DATABASE" | Mount or open a database.
"archivelogRecordSpecifier" | Specify a range of archived redo logs files.
"BACKUP" | Back up database files, copies of database files, archived logs, or backup sets.
"BLOCKRECOVER" | Recover an individual data block or set of data blocks within one or more datafiles.
"CATALOG" | Add information about file copies and user-managed backups to the repository.
"CHANGE" | Mark a backup piece, image copy, or archived redo log as having the status `UNAVAILABLE` or `AVAILABLE`; remove the repository record for a backup or copy; override the retention policy for a backup or copy.
"completedTimeSpec" | Specify a time range during which the backup or copy completed.
"CONFIGURE" | Configure persistent RMAN settings. These settings apply to all RMAN sessions until explicitly changed or disabled.
"CONNECT" | Establish a connection between RMAN and a target, auxiliary, or recovery catalog database.
"connectStringSpec" | Specify the username, password, and net service name for connecting to a target, recovery catalog, or auxiliary database. The connection is necessary to authenticate the user and identify the database.
"CONVERT" | Converts datafile formats for transporting tablespaces and databases across platforms.
"CREATE CATALOG" | Create the schema for the recovery catalog.
"CREATE SCRIPT" | Create a stored script and store it in the recovery catalog.
"CROSSCHECK" | Determine whether files managed by RMAN, such as archived logs, datafile copies, and backup pieces, still exist on disk or tape.
"datafileSpec" | Specify a datafile by filename or absolute file number.
"DELETE" | Delete backups and copies, remove references to them from the recovery catalog, and update their control file records to status `DELETED`.
"DELETE SCRIPT" | Delete a stored script from the recovery catalog.
"deviceSpecifier" | Specify the type of storage device for a backup or copy.
"DROP CATALOG" | Remove the schema from the recovery catalog.
"DROP DATABASE" | Deletes the target database from disk and unregisters it.
"DUPLICATE" | Use backups of the target database to create a duplicate database that you can use for testing purposes or to create a standby database.
"EXECUTE SCRIPT" | Run an RMAN stored script.
"EXIT" | Quit the RMAN executable.
"fileNameConversionSpec" | Specify patterns to transform source to target filenames during `BACKUP` `AS` `COPY`, `CONVERT` and `DUPLICATE`.
"FLASHBACK" | Returns the database to its state at a previous time or SCN.
"formatSpec" | Specify a filename format for a backup or copy.
"HOST" | Invoke an operating system command-line subshell from within RMAN or run a specific operating system command.
"keepOption" | Specify that a backup or copy should or should not be exempt from the current retention policy.
"LIST" | Produce a detailed listing of backup sets or copies.
"listObjList" | A subclause used to specify which items will be displayed by the LIST command.
"maintQualifier" | A subclause used to specify additional options for maintenance commands such as DELETE and CHANGE.
"maintSpec" | A subclause used to specify the files operated on by maintenance commands such as CHANGE, CROSSCHECK, and DELETE.
"obsOperandList" | A subclause used to determine which backups and copies are obsolete.
"PRINT SCRIPT" | Display a stored script.
"QUIT" | Exit the RMAN executable.
"recordSpec" | A subclause used to specify which objects the maintenance commands should operate on.
"RECOVER" | Apply redo logs and incremental backups to datafiles restored from backup or datafile copies, in order to update them to a specified time.
"REGISTER" | Register the target database in the recovery catalog.
"RELEASE CHANNEL" | Release a channel that was allocated with an ALLOCATE CHANNEL command.
"releaseForMaint" | Release a channel allocated with an ALLOCATE CHANNEL FOR MAINTENANCE command.
"REPLACE SCRIPT" | Replace an existing script stored in the recovery catalog. If the script does not exist, then `REPLACE` `SCRIPT` creates it.
"REPORT" | Perform detailed analyses of the content of the recovery catalog.
"RESET DATABASE" | Inform RMAN that the SQL statement `ALTER` `DATABASE` `OPEN` `RESETLOGS` has been executed and that a new incarnation of the target database has been created, or reset the target database to a prior incarnation.
"RESTORE" | Restore files from backup sets or from disk copies to the default or a new location.
"RESYNC" | Perform a full resynchronization, which creates a snapshot control file and then copies any new or changed information from that snapshot control file to the recovery catalog.
"RUN" | Execute a sequence of one or more RMAN commands, which are one or more statements executed within the braces of `RUN`.
"SEND" | Send a vendor-specific quoted string to one or more specific channels.
"SET" | Sets the value of various attributes that affect RMAN behavior for the duration of a RUN block or a session.
"SHOW" | Displays the current `CONFIGURE` settings.
"SHUTDOWN" | Shut down the target database. This command is equivalent to the SQL*Plus `SHUTDOWN` command.
"SPOOL" | Write RMAN output to a log file.
"SQL" | Execute a SQL statement from within Recovery Manager.
"STARTUP" | Start up the target database. This command is equivalent to the SQL*Plus `STARTUP` command.
"SWITCH" | Specify that a datafile copy is now the current datafile, that is, the datafile pointed to by the control file. This command is equivalent to the SQL statement `ALTER` `DATABASE` `RENAME` `FILE` as it applies to datafiles.
"tempfileSpec" | Specifies a tempfile by path or by file number.
"TRANSPORT TABLESPACE" | Creates transportable tablespace sets from backup for one or more tablespaces.
"UNREGISTER DATABASE" | Unregisters a database from the recovery catalog.
untilClause | A subclause specifying an upper limit by time, SCN, or log sequence number. This clause is usually used to specify the desired point in time for an incomplete recovery.
"UPGRADE CATALOG" | Upgrade the recovery catalog schema from an older version to the version required by the RMAN executable.
"VALIDATE" | Examine a backup set and report whether its data is intact. RMAN scans all of the backup pieces in the specified backup sets and looks at the checksums to verify that the contents can be successfully restored.
