Deployment Tasks

Now that you are acquainted with the deployment tools of WebObjects, you are ready to put that knowledge to work by deploying your applications.

This chapter explains how JavaMonitor allows you to perform most of the tasks required to maintain a WebObjects application site with point-and-click ease. The sections below guide you through the process of adding and configuring hosts, applications, and application instances. Also explained is the load-balancing mechanism used by the HTTP adaptor, which performs load balancing among the instances of an application (which can be distributed across more than one host) and how to set up email notifications so that you and your colleagues are notified when problems arise.

This chapter addresses the following subjects:

• “Setting Up Hosts” explains how you add and configure hosts for application deployment. Note that this is different from configuring hosts in the HTTP adaptor.

• “Installing Applications” shows you where to place application files and web server resources on an application host before deploying an application.

• “Setting Up Applications” details the ways you can customize a deployment. These include choosing a load-balancing algorithm and scheduling instances to restart at regular intervals.

• “Configuring Sites” describes the site-wide properties available. These include configuring JavaMonitor to use your SMTP (Simple Mail Transfer Protocol) server to send email notifications.

• “Setting JavaMonitor Preferences” shows you the JavaMonitor-specific settings you can use to tailor the tool’s behavior.

• “Load Balancing” explains how load balancing distributes user load among the running instances of an application in your site.

• “Deploying Multiple Sites” shows how you can maintain multiple sites on one set of computers.
