This isn’t a tutorial on how to code PL/SQL. It’s designed to show you how to code PL/SQL well. It shows you how to write code that will run quickly and won’t break in high-load, multiuser environments. It covers the vast array of the functionality that PL/SQL provides, including effective handling of relational and abstract data, security, triggers, dynamic web content presentation from within the database, creation of a DBA toolkit, and effective debugging techniques. This book sets out to redress the unjust criticism leveled at PL/SQL in years gone by. It gives you the tools and techniques to ensure that, whatever your needs are, the PL/SQL you build will run as efficiently as possible. The practical solutions provided in this book will help you to realize the true power and functionality PL/SQL can offer your projects. Mastering Oracle PL/SQL: Practical Solutions is targeted primarily toward the DBA or developer charged with the implementatio. . . More >>

Oracle Scheduler does a lot of out of the box things, and if the demands are not too high, Oracle Scheduler can cover most of the situations. When your application has to run many thousands of jobs in an hour and log them over a long period, a little more attention is needed. In cases where the demands are high, we need to take care of a few more things to keep the system happy. What we need to do depends on how the Scheduler is used and what kind of load it is supposed to handle.
In this chapter, we will take a closer look at how we can control this beast. We will take a look at the privileges for job creation, job execution, and Scheduler management. We will also examine how to control logging retention and find a way to prevent jobs from running when the database starts.
Like most object types in the database, as seen at the beginning of Chapter 1, Oracle enables us to create Scheduler objects. The privileges create job and create external job are very important. They should normally be used when building an application system . Also, there is a create any job privilege, which can be useful when you need to create a job in a different schema. Normally, this privilege should not be granted to anyone. It will allow the grantee to run an arbitrary code on any schema, which is not particularly desirable. Instead, just log on to the correct schema and perform the tasks using the correct privileges.
