Register Database

Each database to be backed up by RMAN must be registered:

C:>rman catalog=rman/rman@orcl target=sys/orcle@orcl


__________If the above step did not occur then do the below steps--2----

SQL> sho user

USER is "SYS"

SQL> GRANT connect, resource, recovery_catalog_owner TO rman;

Grant succeeded.

Full Backup

First we configure several persistant parameters for this instance:

RMAN> configure retention policy to recovery window of 7 days;

RMAN> configure default device type to disk;

RMAN> configure controlfile autobackup on;

RMAN> configure channel device type disk format 'D:\ORACLE\PRODUCT\10.1.0\ORADATA\rman\Backup%d_DB_%u_%s_%p';


Next we perform a complete database backup using a single command:

RMAN> run {

backup database plus archivelog;

delete noprompt obsolete;

}

Restore & Recover The Whole Database

If the controlfiles and online redo logs are still present a whole database recovery can be achieved by running the following script:

# use abort if this fails

run {

shutdown immediate;

startup mount;

restore database;

recover database;

alter database open;

}

run {

shutdown abort;

startup mount;

restore database;

recover database;

alter database open;

}

run {

startup mount;

restore database;

recover database;

alter database open;

}

run {

restore database;

recover database;

alter database open;

}

---------------
Restore & Recover A Subset Of The Database

A subset of the database can be restored in a similar fashion:



run {

sql 'ALTER TABLESPACE users OFFLINE IMMEDIATE';

restore tablespace users;

recover tablespace users;

sql 'ALTER TABLESPACE users ONLINE';

}

run {

sql 'ALTER TABLESPACE users2 OFFLINE IMMEDIATE';

restore tablespace users2;

recover tablespace users2;

sql 'ALTER TABLESPACE users2 ONLINE';

}
