$

 

You can enter optional commands after the prompts Sqldba> and $ in order to recover errors (e.g. to stop a database, rename a file, etc.). When you have finished, just enter %? to return to ora_recut. You can then decide whether you want to continue the recovery using ora_recut or whether you want to abort it.

!

If the recovery is meanwhile aborted, it is not possible to restart it from

that point any more. The database has to be restored first before a

 

new recovery attempt with ora_recut can be made.

After the recovery is completed ora_recut opens the database using the following command:

database reset logfiles

! The database should be backed up as soon as possible after a successful recovery.

5.2.2Fully-automatic Recovery

In the event of a physical fault in your database you can carry out a fully-auto- matic recovery. You can carry out a fully-automatic recovery with the assistance of the nsrora_rec command.

nsrora_rec [<ORA-SID>]

Under normal circumstances, this file does not require any options. If only one Oracle database is configured, the recovery is also performed immediately. If several databases are configured on this machine, the user is asked to choose a database using the ORACLE_SID. This can also be specified in the call.

#nsrora_rec
