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 wi thin 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 wi thin 30 seconds ... done
(0).
INFO: Getting required database files ... failed.
ERROR-310: Unable to mount the datab ase !
ERROR-350: *** Crash Analyzer failed (RC: >20<) ***
