RMAN configuration step by step in oracle 10g

Step 1: First of all your must mount point out your database using ORACLE_SID in windows ORAENV in linux.
C:>set oracle_sid=samdb
C:>sqlplus “/as sysdba”
SQL*Plus: Release 10.2.0.1.0 – Production on Thu Jan 6 19:51:53 2011 Copyright (c) 1982, 2005, Oracle. All rights reserved. Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 – Production With the Partitioning, OLAP and Data Mining options
SQL> select log_mode from v$database; LOG_MODE ———— ARCHIVELOG

Step2 : Create Rman Tablespace
SQL> CREATE TABLESPACE RMAN01 DATAFILE ‘F:oracleproduct10.2.0oradatasamdbRMAN01.DBF’ SIZE 100M REUSE AUTOEXTEND ON;          Tablespace created.

Step 3: Create RMAN user and password. Here i have been using rman01 and rman01 and assign default tablespace RMAN01 and temporary tablespace TEMP.
SQL> CREATE USER RMAN01 IDENTIFIED BY RMAN01 DEFAULT TABLESPACE RMAN01 TEMPORARY TABLESPACE TEMP;
User created.

Step 4: Grant appropriate permission to rman user (the above user)
SQL> GRANT CONNECT, RESOURCE, RECOVERY_CATALOG_OWNER TO RMAN01;
Grant succeeded.

Step 5: Lanch rman tool.
C:>RMAN
Recovery Manager: Release 10.2.0.1.0 – Production on Thu Jan 6 20:51:53 2011 Copyright (c) 1982, 2005, Oracle. All rights reserved.

Step 6: Connect catalog database using the above rman user.
RMAN> CONNECT CATALOG RMAN01/RMAN01@samdb                                   connected to recovery catalog database

Step 7: Once you connect catalog database immediately run the following query using the given tablespace. RMAN> CREATE CATALOG TABLESPACE RMAN01;               

 recovery catalog created The recovery catalog will store information about target database. 

Step 8: Once connect target databse immediately Register your database. this is called incornation database (reference for the catalog database). Once incarnation database register there are some steps configre targer databaes. The target database that will store information about bacup’s and recovery.

C:> RMAN TARGET / CATALOG RMAN01/RMAN01@ADAPTIME Recovery Manager: Release 10.2.0.1.0 – Production on Thu Jan 6 22:51:53 2011 Copyright (c) 1982, 2005, Oracle. All rights reserved. connected to target database: KEYSTONE (DBID=3390662877) connected to recovery catalog database
