ORA-01113: file string needs media recovery tips

Oracle Error Tips by Burleson Consulting (S. Karam)


Question:  I get this error when starting my Oracle database.  What is the ORA-01113 error?

SQL> alter database open;

alter database open

ERROR at line 1:
ORA-01113: file 1 needs media recovery
ORA-01110: data file 1: 'F:\DB\SYSTEM01.DBF'


Answer:  You should be able to begin Oracle normally after ORA-01113 has been resolved within the database.  The Oracle docs note this on the ORA-01113 error:

ORA-01113: file string needs media recovery
Cause: An attempt was made to online or open a database with a file that is in need of media recovery.

Action: First apply media recovery to the file.

The ORA-01113 error can be thrown when you begin to start Oracle with the "startup" command.  The ORA-01113 has many causes: 

- Bad RMAN cloning
- True file in need of recovery condition

After conforming that the file is need need of recovery, consider issuing the  recover datafile '<datafile-name>'  command to apply the archived redo logs.

As a note, if you are using a standby database, many people often make the mistake of using a hot backup, while forgetting to issue an 'alter tablespace...begin backup...end backup' under tablespace.
