ORA-01152: File 1 was Not Restored From a Sufficiently Old Backup

Oracle Database Tips by Donald BurlesonJune 14, 2015

Question:  I am performing a database recovery and I get this ORA-01152 error:

SQL> alter database open
2 ;
alter database open

ERROR at line 1:
ORA-16004: backup database requires recovery
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '+DATA/dprod/datafile/system01.dbf'

How do I get around this ORA-01152 error and restore my database?

Answer:  We start by using the oerr utility for information on the ORA-01152 error:

ORA-01152: file 1 was not restored from a sufficiently old backup  

Cause: An incomplete recovery session was started, but an insufficient number of logs were applied to make the database consistent. This file is still in the future of the last log applied. The most likely cause of this error is forgetting to restore the file from a backup before doing incomplete recovery.

Action: Either apply more logs until the database is consistent or restore the database file from an older backup and repeat recovery.  

As you see, you need to take one of the following actions to alleviate the ORA-01152 error:

  •  Continue to apply logs from your archived redo log filesystem: Ensure that you are in ARCHIVELOG mode and check your redo log file destination to ensure that you have enough redo logs.  If you are in NOARCHIVELOG mode, the only way to get around the ORA-01152 error is to perform a full restore from your last cold backup, losing any updates since the backup was taken.  This will most likely result in you getting fired for ineptitude.
  •  Restore from an older backup:  If you restore from an older backup the ORA-01152 error will not appear because Oracle will be able to fully recover the database into a consistent state.
