Which two new features of the Oracle 10g database could you use to automate this task?

In an online transaction processing (OLTP) environment, you find that the transaction tables get heavily fragmented during the week. You decide to defragment the transaction tables on every Friday at 9:30 p.m. to gain performance. Which two new features of the Oracle 10g database could you use to automate this task? (Choose two)

A.
The DBMS_AQ package

B.
The DBMS_JOB package

C.
The OS level job automation tool

D.
The DBMS_SCHEDULER package

E.
Enterprise Manager job scheduling

Explanation:
D: Oracle 10g’s new DBMS_SCHEDULER package offers significant improvements over DBMS_JOB for scheduling jobs and tasks.
Here is an example of scheduling with DBMS_SCHEDULER. Note that the syntax is now much clearer, and the parameters even now make sense when compared to DBMS_JOB. And gone at last is that wacky INTERVAL parameter! BEGIN DBMS_SCHEDULER.CREATE_JOB ( job_name => ‘HR_STATS_REFRESH’ ,job_type => ‘PLSQL_BLOCK’ ,job_action => ‘BEGIN
DBMS_STATS.GATHER_SCHEMA_STATS("HR");END’; , START_DATE => ’09/01/2004
09:30 PM’ ,repeat_interval => ‘WEEKLY BYDAY=5’ ,enabled => TRUE ,comments => ‘ Refreshes the HR schema every friday at 9:30 PM’) ; END; Not B: DBMS_JOB is not new with 10g)
