V. Resync the catalog with the target controlfile
VI. Delete a backup
VII. Backup a database
VIII. Restore/recover a database
IX. Show the controlfile backup record
X. Misc commands

Create a catalog
create a tablespace
create a user
grant connect, resource, recovery_catalog_owner to user;

rman catalog user/pass@db
create catalog tablespace "";

Note. is case sensitive (i.e. it must be uppercase)

Note. If you get the error 'rman: can't open catalog', make sure that oracle's rman is being run (which rman). X11 also has a command called rman. Rename it if necessary.
Register a database
Note. ensure the target db has a password file
rman catalog user/pass@rmandb target user/pass@db

register database


Un-register a database
sqlplus user/pass@rmandb
select * from rc_database;
select db_key, db_id from db;

execute dbms_rcvcat.unregisterdatabase(, );


Reset the catalog after a restlogs on the target
reset database;


Resync the catalog with the target controlfile
resync catalog;


Delete a backup
allocate channel...
delete backuppiece ;
release channel;


Backup a database
backup database plus archivelog format '/u01/ora_backup/rman/%d_%u_%s';

run {
allocate channel t1 type disk;
backup current controlfile format '/u01/ora_backup/rman/%d_%u_%s';
backup database format '/u01/ora_backup/rman/%d_%u_%s';
backup archivelog all delete input format '/u01/ora_backup/rman/arch_%d_%u_%s';
release channel t1;
}

run {
allocate channel t1 type disk;
backup archivelog all delete input format '/u01/ora_backup/rman/arch_%d_%u_%s';
release channel t1;
}
Cold backup (archivelog or noarchivelog mode)
run {
allocate channel t1 type disk;
shutdown immediate;
startup mount;
backup database include current controlfile format '/u01/ora_backup/rman/%d_%u_%s';
alter database open;
}

run {
allocate channel t1 type disk;
backup archivelog all delete input;
}


Restore/recover a database
Full restore and recovery
startup nomount;
run {
allocate channel t1 type disk;
allocate channel t2 type disk;
allocate channel t3 type disk;
allocate channel t4 type disk;
restore controlfile;
restore archivelog all;
alter database mount;
restore database;
recover database;
}
sql 'alter database open resetlogs';
Restore and roll forward to a point in time
startup nomount;
run {
set until time ="to_date('30/08/2006 12:00','dd/mm/yyyy hh24:mi')";
allocate channel t1 type disk;
allocate channel t2 type disk;
allocate channel t3 type disk;
allocate channel t4 type disk;
restore controlfile;
restore archivelog all;
alter database mount;
restore database;
recover database;
}
sql 'alter database open resetlogs';

If the archive logs are already in place:

startup mount;
run {
set until time ="to_date('08/02/2007 14:00','dd/mm/yyyy hh24:mi')";
allocate channel t1 type disk;
allocate channel t2 type disk;
allocate channel t3 type disk;
allocate channel t4 type disk;
restore database;
recover database;
}
sql 'alter database open resetlogs';

startup mount;
run {
allocate channel t1 type disk;
recover database;
}


Show the controlfile backup record
set pages 999 lines 100
col name format a60
break on set_stamp skip 1
select set_stamp
, to_char(ba.completion_time, 'HH24:MI DD/MM/YY') finish_time
, df.name
from v$datafile df
, v$backup_datafile ba
where df.file# = ba.file#
and ba.file# != 0
order by set_stamp, ba.file#
/
