  2. A warning message will be written to the alert log of the database, but no adverse impacts to the database will be experienced.

  3. The database will shut down, and will not restart until you correct the out-of-space situation.

  4. The database will continue to try to write to the archive-log destination directory for one hour. After one hour, the database will shut down normally.

  5. Once Oracle has cycled through all online redo logs, it will stop processing any DML or DDL until the out-ofspace condition is corrected.

If a log file becomes corrupted, it may cause the database to stale. How would you correct such a situation?

  1. Recover the online redo log from backup.

  2. Delete and re-create the log file.

  3. Use the ALTER DATABASE CLEAR LOGFILE command to clear the log file.

  4. Shut down the database and restart it.

  5. Shut down the database and then mount it. Clear the log file with the ALTER DATABASE CLEAR LOGFILE command and then restart the database with ALTER DATABASE OPEN RESETLOGS.

Answer: C Explanation:

If you don#39;t use the ALTER DATABASE CLEAR LOGFILE command to clear log online, after the database restarted, the log file will be INVALID.

So the simple way is to clear the log file directly.
