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.

JBoss AS 5 Development is a new book from Packt which helps developers create and secure their Java applications on the JBoss application server. Written by software architect Francesco Marchioni, this book teaches users how to develop, configure and deploy a complete Java EE application using JBoss AS.
JBoss Application Server is the most commonly used Java application server and is a Java EE certified platform for developing and deploying enterprise Java applications, Web applications and Portals. This book is a walk through the basics of JBoss AS such as installation of core components, JBoss Tools and plug-ins, along with covering advanced topics like developing applications with JBoss Messaging service, JBoss and Hibernate , JBoss web services, clustered applications etc.
Developers will learn to install a suitable environment for developing enterprise applications on JBoss AS and then customize each service for optimal usage. They will also learn to design Enterprise applications using Eclipse and JBoss plug-ins and learn how to enable distributed communication using the new JMS Provider: JBoss Messaging service.
This book will help users integrate Hibernate applications into the application server architecture, and see how they can store and retrieve objects using Hibernate. It also explains the theory of clustering and how to develop a Clustered Application along with secure their applications using JBoss security framework.
Java architects, developers and JBoss administrators working on JBoss application servers will find this book interesting and useful. This book is out now and available from Packt. You can read more about this book here: www.packtpub.com/jboss-as-5-development/book

This book shows you how to use NetBeans functionality to automate many of the tedious or repetitive tasks frequently encountered when developing enterprise Java applications, freeing up the developer to focus on the business logic specific parts of the application.
Java EE, the successor to J2EE, greatly simplifies the development of enterprise applications. The popular IDE, NetBeans, has several features that greatly simplify Java EE development, and this book shows you how to make use of these features to make your Java programming more efficient and productive than ever before.
With many features and great flexibility, the Java developer can become overwhelmed by the options available in NetBeans, This book helps you get control of the environment, and make it work for you so that you can concentrate on the important parts of your application.
This book takes you through the most important parts of Java EE programming and, with clear, careful instructions and screenshots, shows you how to use the features of NetBeans that will improve your development experience. This book will not only show you time-saving tricks, keyboard shortcuts and other productivity enhancements possible with NetBeans, it will take you through the major Java EE APIs and how to get them working in the NetBeans environment.
While focusing on NetBeans features, you will learn about developing applications using the servlet API and JSPs, including taking advantage of JSTL and developing custom JSP tags. Developing applications that take advantage of JavaServer Faces is also covered in detail, including how to generate standard JSF applications from an existing database schema. The book also covers how to easily develop elegant JSF applications by taking advantage of the NetBeans Visual Web designer.
The book is aimed at Java developers who wish to develop Java EE applications while taking advantage of NetBeans functionality to automate repetitive tasks and to ease their software development efforts. Familiarity with Java EE is not assumed.
