Recovery Manager is a great tool for backup, restore and recovery operations. Here is a practical setup procedure to get you started.
Setting up the RMAN environment involves several steps. Assuming you'd like to take advantage of the benefits provided by a recovery catalog (recommended), you must install the RMAN catalog. For anything but easily-recreated test environments, this would be done on a separate machine from the target database. Here is a summary of the steps:
Install recovery catalog on separate database
- Set up a DB to hold recovery catalog
- Create a tablespace to hold recovery catalog
- Create user RMAN
- Grant privileges to RMAN
Register the target database
- Connect to RMAN
- Create recovery catalog
- "Register" the target DB(s) in the new catalog
Execute this code from SQL*Plus, logged in as SYSTEM, and connected to your CATALOG database (i.e., the database you want to build your recovery catalog on). It will need to be adjusted to reflect the correct OS file paths and the service name of your recovery and target databases:
-- Setup RMAN with a recovery database.
-- Create a tablespace to hold the recovery catalog.
create tablespace rmancatalog datafile 'c:\oracle\oradata\prod\rman\catalog.dbf' size 50m;
create user rman identified by rman temporary tablespace temp default tablespace rmancatalog quota unlimited on rmancatalog;
grant recovery_catalog_owner, connect, resource to rman;
-- Log any errors.
$rman catalog rman/rman@prod log=c:\rman\rman_create_catalog.log cmdfile=c:\rman\createcatalog.rman
$rman target=sys/change_on_install@prod catalog=rman/rman@prod log=c:\rman\rman_register_db.log cmdfile=c:\rman\registerdb.rman RMAN Script: createcatalog.rman create catalog; exit; RMAN Script: registerdb.rman register database; exit;
