Examine this list of possible tasks: 1. Ensure that STATISTICS_LEVEL is set to TYPICAL or ALL. 2. Ensure that TIMED_STATISTICS is set to TRUE. 3. Set MAX_DUMP_FILE_SIZE to UNLIMITED and DIAGNOSTIC_DEST to an appropriate destination. 4. Ensure that SQL_TRACE is set to TRUE. 5. Enable tracing at the database instance level by using the DBMS_MONITOR.DATABASE_TRACE_ENABLE procedure. 6. Enable tracing in the required session by using the DBMS_SESSION.SET_SQL_TRACE procedure. 7. Run TKPROF with the EXPLAIN parameter on the output trace file. 8. Run the trcsess utility on the output trace files, and then run TKPROF on the output of the trcsess utility. Select the minimum tasks to perform, in the correct order, to generate both a formatted trace file with timing information and an explain plan for each SQL statement for all sessions. (Choose the best answer.)
