Chapter 18: Deploying Applications

Overview

An OC4J administrator's primary duties are setup, configuration, monitoring, and application deployments. In the previous chapter you saw how OC4J is architected, configured, and monitored . This chapter will focus on how the administrator deploys J2EE applications provided by the developers. We'll show how the administrator acts as a deployer to take a Java application from the developers and deploy it into a production 10g AS environment. You'll do this with the GUI Application Server Control (ASC) utility and via the command line with dcmctl . Finally, we'll show you how to change some application-specific settings via the ASC utility.

In this chapter, we'll cover the following:

• Deployment overview. How applications are developed and released within 10g AS

• Creating a dedicated OC4J instance. How to create a dedicated OC4J instance to support a specific application

• Deploying and undeploying an application via the ASC. Using the ASC tool to deploy and undeploy applications is quick and easy

• Deploying and undeploying an application via command line dcmctl commands. The ability to deploy applications via the command line is useful and we show you how
