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 "<tablespace_name>";

Note. <tablespace_name> 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(<db_key>, <db_id>);

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 <number>;
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#
/
