The resulting trace file. Answer: C Explanation: The resulting trace file should be used to diagnose the problem and determine how to prevent the deadlock from occurring again in the future. When Oracle's deadlock detection mechanisms discover a deadlocking situation on the database, they write a message to the ALERT lo for the Oracle instance. The DBA should take note of the "deadlock detected while waiting for a resource" error messages, and any included process information from the ALERT log sent to assist the DBA in determining the cause of the deadlock.

Both the background process trace files and the ALERT log will be found in this directory. Incorrect Answers: A: UTL_FILE_DIR parameter represents directory for different purpose, not for background processes trace files. B: CORE_DUMP_DEST parameter shows directory for core files, not for trace files. C: LOG_ARCHIVE_DESC directory is used for archived redo log files. - The Power of Knowing 1Z0-024 Oracle 8,...
