Extract Archived Log Files from RMAN Backupset

archivebackuporacle-11g-r2rman

I have an RMAN backup that is taken on 19th january with: BACKUP DATABASE PLUS ARCHIVELOG command. Now I need to restore Archived logs from that backupset to some other OS directory. Is there any way to extract Archived Log files from that backup?

You probably need to use catalog, because a long time passed since January.

rman target / catalog rman_catalog_user@rman_catalog_db

RUN
{ 
  SET ARCHIVELOG DESTINATION TO '/oracle/temp_restore';
  RESTORE ARCHIVELOG FROM TIME = "to_date('2014-01-19 19:20:00','YYYY-DD-MM HH24:MI:SS')"  
                    UNTIL TIME = "to_date('2014-01-19 20:00:00','YYYY-DD-MM HH24:MI:SS')";
}

Each redo log file (and archived redo log file) contains starting SCN and ending SCN. In case it is a last redo, the ending SCN is 0xffffffffffff.

Until database sees 0xffffffffffff it keeps asking for further logs. But it is not a problem, you can specify UNTIL SCN or UNTIL CANCEL for your recovery (this means you don't want a complete recovery, in other words you want to lose some recent data).

Failure Of Backup Due To Limit Exceeded For Recovery Files Since Cannot Reclaim Disk Space [RMAN-03009,ORA-19809,ORA-19804]

The db_recovery_file_dest includes a variety of files, including online AND archived redo log files; take a look at the Oracle Backup and Recovery User's Guide chapter 5 to find out the best solution; disabling db_recovery_file_dest is not a good idea. You can try

RMAN> report obsolete;

RMAN command to see what can be deleted. Then do a delete obsolete to delete them. Do you have any guaranteed restore points defined?

RMAN> list restore point all;

If you see any results with type GUARANTEED, if they are no longer needed, remove them:

SQL> DROP RESTORE POINT before_app_upgrade;

Is flashback database enabled?
