Recovery

Performing a recovery

INFO: Following database files are required to perform a recovery:

/oracle/7_0_16/dbs/benutzer1NSR.dbf INFO: *** Crash Analyzer finished ***

INFO: *** Invoking Database Restauration ***

INFO: Trying to restore /oracle/7_0_16/dbs/benutzer1NSR.dbf

recover: Using ufo as server for ufo Recovering 1 file into its original location

Total estimated disk space needed for recovery is 4.1 MB Requesting 1 file, this may take a while ...

./benutzer1NSR.dbf

Received 1 file(s) from NSR server ’ufo’ INFO: *** Database Restauration finished ***

INFO: *** Invoking Database Recovery ***

INFO: Mounting the database ... was previously done.

INFO: Ensure that all database files are online ... done.

INFO: Recovering the database.

INFO: Database accessible.

INFO: Recovery finished successfully!

INFO: *** Database Recovery finished ***

The second example deals with a situation in which all database files are intact. In this case, an appropriate message is displayed after the database has been analyzed:

#nsrora_rec

INFO: *** Invoking Crash Analyzer ***

INFO: Trying to shutdown database within 30 seconds ... done (20).

INFO: Getting required database files ... done.

INFO: No damaged files found !

INFO: *** Crash Analyzer finished ***

INFO: *** No Database recovery required (RC: >5<) ***

Finally, the third example demonstrates the behavior of the crash analyzer in a situation in which an automatic recovery is not possible (e.g. when a control file is lost). You will have to carry out a manual recovery in such cases:

#nsrora_rec

INFO: *** Invoking Crash Analyzer ***

INFO: Trying to shutdown database within 30 seconds ... done

(0).

INFO: Getting required database files ... failed.

ERROR-310: Unable to mount the database !

ERROR-350: *** Crash Analyzer failed (RC: >20<) ***
