Recovery Manager commands.
BACKUP Back up database files, archive logs, backups, or copies. CATALOG Add information about files to the repository. (10g+) CHANGE Update the status of a backup in the RMAN repository. CONFIGURE Persistent RMAN settings. CONNECT Connect to a recovery catalog or auxiliary database CROSSCHECK Check whether backup items still exist. DELETE Delete backups from disk or tape EXIT Exit the RMAN console LIST List backups and copies RECOVER Apply redo logs or incremental backups to a restored backup set (or copy) in order to update it to a specified time. REPORT Report backup status: database, files, backups RESTORE Restore files from an RMAN backup (or copy) RUN Some RMAN commands are only valid inside a RUN block. SET Settings for the current RMAN session. SHOW Display the current configuration SHUTDOWN Shutdown the database SQL Execute a PL/SQL procedure or SQL statement(not SELECT) STARTUP Startup the database ADVISE FAILURE Display repair options (11g Data Recovery Advisor) REPAIR FAILURE Repair database failures (11g Data Recovery Advisor) Examples: Full DR recovery, Point in time recovery (assumes archive log mode)
Start RMAN without connecting to a database
Start RMAN and run a command file:
$ rman @/scripts/rman_commands.txt
Connect to a target database and a recovery catalog:
$ rman TARGET SYS/pwd CATALOG cat_usr/pwd@cat_str
Connect to a target database without using a recovery catalog:
$ rman TARGET SYS/pwd@sid NOCATALOG
Connect to a target database and log a full debug trace file:
$ rman TARGET SYS/pwd NOCATALOG debug trace=rman.trc log=rman.log
Connect to a target database and log output messages to a file:
$ rman TARGET SYS/pwd log=rman.log APPEND
Run a command file from the RMAN prompt:
In interactive mode, RMAN displays an "RMAN>"> prompt
The commands above may be entered directly at the RMAN> prompt or used within a command file. To quit, type
RMAN records it's backup activity in the database control file.
Optional Components of RMAN:
The recovery catalog database, a separate database used to record RMAN activity against one or more target databases. RMAN's
SHOWcommands display information from this repository. It is also possible for one database to store both the RMAN repository and other data. Typically this would be a Test or Train instance (with the repository data in a separate RMAN schema.)
The flash recovery area, a disk location in which the database can store and manage files related to backup and recovery.
Media management software, for interface with tape drives/libraries.
Set the flash recovery area size and location, using
CONTROL_FILE_RECORD_KEEP_TIME controls how long backup records are kept in the control file before those records are
re-used to hold information about more recent backups.
For simplicity the syntax on this page does not cover every command available; it is based on commands that are common to both Oracle 9.2 and Oracle 10g (10.1) 10g has greatly improved RMAN data dictionary views for reporting.
RMAN was first introduced in Oracle 8.0
