oracle 9i -RMAN-20201 datafile not found in the recovery catalog:

Certo dia tivemos um problema com uma tablespace de dados que nao estava mais no catalogo do RMAN, ao verificarmos a mesma  tinha sido deletada e  ao tentar  restaurar apenas o backup full:
#restaurando o backup full
shutdown immediate;

startup nomount;

alter database mount;

run{
set newname for datafile 1 to 'D:\oracle_novo\ora90\oradata\brasil\system01.dbf';
 set newname for datafile 2 to 'D:\oracle_novo\ora90\oradata\brasil\undotbs01.dbf';
 set newname for datafile 3 to 'D:\oracle_novo\ora90\oradata\brasil\cwmlite01.dbf';
 set newname for datafile 4 to 'D:\oracle_novo\ora90\oradata\brasil\drsys01.dbf';
 set newname for datafile 5 to 'D:\oracle_novo\ora90\oradata\brasil\example01.dbf';
 set newname for datafile 6 to 'D:\oracle_novo\ora90\oradata\brasil\indx01.dbf';
 set newname for datafile 7 to 'D:\oracle_novo\ora90\oradata\brasil\tools01.dbf';
 set newname for datafile 8 to 'D:\oracle_novo\ora90\oradata\brasil\users01.dbf';
set newname for datafile 9 to 'D:\oracle_novo\ora90\oradata\brasil\tbs_dados_01.dbf';
set newname for datafile 10 to 'D:\oracle_novo\ora90\oradata\brasil\tbs_dados_02.dbf';

 SET UNTIL SCN 268118;
 RESTORE DATABASE;
 SWITCH DATAFILE ALL;
 RECOVER DATABASE;
 }

Apareceu a mensagem de erro:
RMAN-20201 datafile not found in the recovery catalog.
RMAN-06010 error while looking up datafile 9

Ao fazer a busca pelo backups verificamos que a tablespace deletada estava sendo encontrada:

alter database open;

RMAN> list backup;

Para resolver esse problema foi necessário primeiro restaurar o controlfile do ultimo bkp full.

shutdown immediate;

startup nomount;

restore controlfile from 'd:\oracle_novo\backup\testebkpfullcomnfe_300810.bkp';

shutdown immediate;


startup nomount;


alter database mount;

alter database open resetlogs;

RMAN> list backup;
