For this book, I carried out an out of the box installation on Enterprise Linux with the Oracle-validated package applied to it. I made a simple database using DBCA, complete with sample schemas and DB Console. For storage, I made use of an NAS and openfiler on a separate installation presented as iSCSI targets.
Let's get started with simple jobs.
Simple jobs are the jobs that can easily be created using DB Console with little or no extra object creations required. The quickest way to get you started is by making the database perform actions for you. A simple job is not the same as a useless job. Far from that, many tasks can be performed using simple jobs. Sometimes we can go back and use easy, single-step jobs rather than using advanced jobs based on complicated rules.
The DB Console does provide some support for the Scheduler, which can be used for simple tasks. However, for more elaborate things we need to use a PL/SQL editor. Any PL/SQL-capable tool will do. If you like, use SQL*Plus, SQL Developer, DbVisualizer, or TOAD for a Windows-centric client. Let's start using DB Console and see what this gives us.
