Mastering Oracle Scheduler in Oracle 11g Databases

Overview of this book

Scheduler (DBMS_SCHEDULER) is included in Oracle Database and is a tool for the automation, management, and control of jobs. It enables users to schedule jobs running inside the database such as PL/SQL procedures or PL/SQL blocks, as well as jobs running outside the database like shell scripts. Scheduler ensures that jobs are run on time, automates business processes, and optimizes the use of available resources. You just need to specify a fixed date and time and Scheduler will do the rest. What if you don't know the precise time to execute your job? Nothing to worry about, you can specify an event upon which you want your job to be done and Scheduler will execute your job at the appropriate time. Although scheduling sounds quite easy, it requires programming skills and knowledge to set up such a powerful, intelligent scheduler for your project. This book is your practical guide to DBMS_SCHEDULER for setting up platform-independent schedules that automate the execution of time-based or event-based job processes. It will show you how to automate business processes, and help you manage and monitor those jobs efficiently and effectively. It explains how Scheduler can be used to achieve the tasks you need to make happen in the real world. With a little understanding of how the Scheduler can be used and what kind of control it gives, you will be able to recognize the real power that many known enterprise-class schedulers ñ with serious price tags ñ cannot compete with. You will see how running a specific program can be made dependent on the successful running of certain other programs, and how to separate various tasks using the built-in security mechanisms. You will learn to manage resources to balance the load on your system, and gain increased database performance.

Silent install of the remote job agent

When you decide to use the remote job agent, there will be a lot of installation work. We can use the interactive installer as described before, but this can also be done in a much faster way by using the silent install option. This will work best when the machines on which you are installing have uniform installation. First, decide what the ORACLE_HOME_NAME and ORACLE_HOME locations will be. This is the standard for all silent Oracle installations. For the agent, we also need HOST_NAME and PORT where the agent will listen at the time of installation. We can easily change that later, as most of us prefer to do. Here we will see the installation of the base release followed by the patch.

Base release

For the base release, use the same Gateways CD that we used in the interactive installation. Just change the current directory to the gateways directory where you can see the runInstaller executable. The base release is We will immediately upgrade...
