+-- | PURPOSE  : This script is responsible to configure a DBMS Job to be run    |
+-- |            every 30 minutes starting at the quarter of each hour. For      |
+-- |            example, if this script is run at 10:32 pm, the first job will  |
+-- |            be run at 11:00 pm, then the next job at 11:30 pm and so on     |
+-- |            every 30 minutes.                                               |
+-- | NOTE     : As with any code, ensure to test this script in a development   |
+-- |            environment before attempting to run it in production.          |

+prompt The following script will create a new DBMS Job to be run at the quarter
+prompt of each hour. (i.e. Every 30 minutes). The job will perform a Statspack
+prompt snapshot using the Oracle supplied STATSPACK package.
+prompt 
+prompt Note that this script should be run as the owner of the 
+prompt STATSPACK repository. (i.e. PERFSTAT)
+prompt This script will prompt you for the PERFSTAT password.

+prompt Also note that in order to submit and run a job, the init.ora parameter
+prompt job_queue_processes must be set to a value greater than zero.
