RMAN Basics:

Step 1: Create a user to store the RECOVERY CATALOGAlso create a seperate tablespace for the user (Though it is not

necessary)

create tablespace madhu_rman datafile 'H:\app\Administrator\orad

ata\orcl\m_rman01.dbf' size 100M reuse autoextend on next 64k maxsize 3G;

create user rman identified by posidex default tablespace madhu_rman temporary tablespace temp quota unlimited on madhu_rman;

grant connect,resource,recovery_catalog_owner to rman;

Step 2: Create the RECOVERY CATALOG

From command prompt

C:>rman catalog=rman/posidex@orcl

rman>create catalog tablespace "MADHU_RMAN";CAUTION NOTE: the tablespace specified is case sensitive. ie., As the created tablespace name is stored in upper case in oracle, it should be given in upper only in the above command or else it throws the following error.

-----------------------error creating db

ORACLE error from recovery catalog database: ORA-00959: tablespace 'madhu_rman'does not exist

ORACLE error from recovery catalog database: ORA-00942: table or view does not exist

rman>exit

Step 3: Each database to be backup up by RMAN should be registered:

From command prompt

C:>rman catalog=rman/posidex@orcl target=sys/madhu@orclrman> register database;It gives the following messages

database registered in recovery catalogstarting full resync of recovery catalogfull resync complete

Step 4: Backup the database

RUN{

FORMAT = 'G:\orcl_db.bak';BACKUP DATABASE PLUS ARCHIVELOG;

}
