Weblogic Installation

Choosing a Type of Installation

The WebLogic Platform installation program provides two types of installation: Complete and Custom.

Complete Installation

In a complete installation, the following components are automatically installed:
  • All software components included in the distribution. Software components vary depending on the software distribution method:
    • WebLogic Platform Package Installer or CD-ROM—all the software components provided with WebLogic Platform, including sample files, as described in WebLogic Platform Software Components. Sample domains, as well as the WebLogic Platform Tour, are preconfigured for use with the PointBase database, allowing you to start running the samples as soon as the installation is complete.
    • WebLogic Server Package Installer—WebLogic Server and WebLogic Workshop program files and all related sample files.
    • Net Installer—All WebLogic Platform components, including WebLogic Server, WebLogic Workshop, WebLogic Integration, WebLogic Portal, and all related sample files.
  • Two SDKs are installed on Windows platforms only: the Sun Java 2 SDK 1.4.2 and the BEA JRockit 1.4.2 SDK. For more information, seeBEA JRockit SDK.
The WebLogic Server Node Manager is not installed as a Windows service.

Custom Installation

In a custom installation, you have the following options:
  • You can choose which software components to install on your system. For a description of the software components provided with WebLogic Platform, see WebLogic Platform Software Components.
  • You can choose whether to install the WebLogic Server Node Manager as a Windows Service. See Installing the Node Manager as a Windows Service. Sample domains preconfigured to use the PointBase database are created only for the installed components.
On Windows platforms, two SDKs are installed: the Sun Java 2 SDK 1.4.2 and the BEA JRockit 1.4.2 SDK. For more information, see BEA JRockit SDK.

Installing the Node Manager as a Windows Service

When installing WebLogic Platform on a Windows platform, you can optionally install the WebLogic Server Node Manager as a Windows service. The WebLogic Server Node Manager is used to:
  • Start and stop managed servers in a domain.
  • Monitor the self-reported health of managed servers and automatically kill server instances whose health state is "failed."
  • Automatically restart managed servers that have the "failed" health state, or have shut down unexpectedly due to a system crash or reboot.
In a custom installation, you can optionally install the Node Manager as a Windows Service. In a production environment, you usually install the Node Manager only on server machines that host managed server instances of WebLogic Server. The WebLogic Server Node Manager is not installed as a Windows service in a complete installation. In a development environment, you may want to install the Node Manager on a server machine that hosts both the administration server and managed server instances of WebLogic Platform.
The Node Manager is installed as a Windows service only under the following conditions:
  • You are installing on a Windows platform.
  • You are performing a custom installation.
  • The Node Manager for the current version of WebLogic Platform is not already installed on the server.
After you install the Node Manager as a Windows service, the service is started the next time you reboot the system. You can also manually start the service from the Windows Services control panel.
When you uninstall WebLogic Platform, the service is uninstalled also.
Notes: By default, the WebLogic Server Node Manager uses port 5555. If the Node Manager for a previous version of WebLogic Server is installed on the machine, the new version does not start when Windows starts because of port contention. To make sure that the new version starts when Windows starts, reconfigure the Node Manager to use a different port.
The BEA Node Manager service is linked to a BEA Home directory. If you have multiple BEA Home directories on your machine and you uninstall WebLogic Platform in the BEA Home directory linked to the Node Manager service, the uninstaller removes the service. If you have other instances of WebLogic Server that rely on the Node Manager, you must manually start the Node Manager or reinstall the Node Manager service.
If you uninstall an instance of WebLogic Platform that is not in the BEA Home directory linked to the Node Manager service, the uninstallation program does not uninstall the Node Manager service.
For more information about the Node Manager, including instructions for installing it on a UNIX server, see the following topics in Configuring and Managing WebLogic Server:
