Validate and recover database irrecoverable data loss (Incomplete recovery)
On this scenario, we’ve been very bad guys and have no good controlfile backup from a recent archive backup, and also had lost some archivelog (let’s guess that the archivelogs lived on the FRA and all the diskgroups where corrupted). That means we have lost some data in time, but on some recovery scenarios, that means better than having nothing, for instance, on non production environments.
This database doesn’t fit on a tipical development environment, though, as it’s on archivelog mode. Anyway, it’s a perfectly valid example as the only valid database backup is an old full backup, and that’s definitely a damn development scenario. The SAN storage is quite old, did something weird and completely corrupted all development data, and all we have is an old last week’s full backup…WTH…
How we get to know this? After recovering the hardware outage, the database starts, but the rman validate command finds data corruption:

Good! Then, we’ll see what excatly means, as the database started and open with no erros…

Now we see some light (or to day better, darkness). We had some data corruption on the SAN storage outage…
We try to restore only that datafile with RMAN:
SQL> alter database datafile 3 OFFLINE; Database altered. SQL> recover datafile 3; ORA-00283: recovery session canceled due to errors ORA-01110: data file 3: '+DATA/racora/datafile/undotbs1.269.729858657' ORA-01122: database file 3 failed verification check ORA-01110: data file 3: '+DATA/racora/datafile/undotbs1.269.729858657' ORA-01210: data file header is media corrupt
Ouch! OK, this is a controlled error, we can bypass it by removing the datafile manually and then performing the restore:

If after all of this, your database still doesn’t opens, saying that datafile 1 (System tablespace datafile) needs recovery, then we’ll have to dismiss all data from last controlfile backup.
As we said, all we have is a full backup including controlfile. We’ll restore the controlfile from that backup and recover the database to that controlfile’s SCN.
First of all, we recover the controlfile with the database started in “nomount” mode:
