Configuring external WebSphere application servers

You can create middleware server representations of WebSphere® application servers that are in other cells.

Before you begin

About this task

External WebSphere application servers are application servers that reside outside of your WebSphere Virtual Enterprise cell. For example, you might have two cells: one cell that is running WebSphere Application Server Version 5.1 application servers, and another cell that is running WebSphere Virtual Enterprise. In this scenario, you can install the middleware agent on the Version 5.1 nodes in the other cell, federate these nodes into your WebSphere Virtual Enterprise cell, and create representations of your external WebSphere application servers in your WebSphere Virtual Enterprise administrative console. Using external WebSphere application servers can be useful in a migration scenario because you can continue to route traffic to servers that are running an older version with the ODR while you work on migrating your servers and applications to the latest version. However, external WebSphere application servers are assisted life-cycle servers and therefore do not receive the full life-cycle management that is provided when you create application servers directly in your WebSphere Virtual Enterprise cell.

When you configure the external WebSphere application servers, if you installed WebSphere Application Server in a location other than the default directory, update the WebSphere Variables so that the installation directory is correct. To perform server operations on your server from the administrative console, you must configure the server operations for the WebSphere Application Server middleware server representation.

Procedure

  1. Update the WebSphere variables so that they match the settings on the node that is running the WebSphere Application Server. In the administrative console, click Environment > WebSphere Variables. Edit the following variables:
    WAS51_HOME
    Specifies the location of the WebSphere Application Server Version 5.1 installation.
    Default values are set at the cell scope level:
    [For Windows operating system] c:\Program Files\IBM\WebSphere\AppServer
    [For Unix operating system] /opt/IBM/WebSphere/AppServer

    If the home directory is different on different nodes in your configuration, select the node scope and create the WAS51_HOME variable for the specific node.

    WAS6_HOME
    Specifies the location of the WebSphere Application Server Version 6 installation location.
    Default values are set at the cell scope level:
    [For Windows operating system] c:\Program Files\IBM\WebSphere\profiles\AppServer
    [For Unix operating system] opt/IBM/WebSphere/profiles/AppServer

    If the home directory is different on different nodes in your configuration, select the node scope and create the WAS6_HOME variable for the specific node.

    WAS6_PROFILE_NAME
    Specifies the name of the profile in which the external WebSphere Application Server server resides on its physical computer.
  2. Update server operations for the WebSphere Application Server to include the user name and password.
    1. In the administrative console, click Servers > Other middleware servers >External WebSphere Application Server > WebSphere_Application_Server > Server operations.
    2. Edit the start and stop server operations to include the user name and password that is required to run these commands.
