Overview
The SunPlex Manager installs Sun Java System Web Server (formerly Sun ONE Web Server) from the Sun Java System distribution. You can configure Sun Cluster HA for Sun Java System Web Server as a scalable data service or as a failover data service. For a list of the releases of Sun Java System Web Server supported by Sun Cluster, contact your Sun sales representative.
Note: By running the Sun Java System installation, you agree to the terms of the Sun Java System LICENSE.txt file.
Note: You need to install multiple instances of Sun Cluster HA for Sun Java System Web Server if:

- The location of the configuration files and installation files is different for each instance.
- The ports do not conflict.

Note: If you are running multiple data services in your Sun Cluster, usually you can set up the data services in any order. However, if Sun Cluster HA for Sun Java System Web Server depends on Sun Cluster HA for DNS, you must set up DNS first. DNS software is included in the Solaris operating environment. If the cluster gets the DNS service from another server, then configure the cluster to be a DNS client first.

For a more advanced configuration, use the Administrative Console to manually customize your Sun Cluster configuration after SunPlex Manager completes the installation. For more control over the installation than SunPlex Manager provides, perform the installation manually using the procedures in the Sun Cluster documentation.

Before Starting
Before you install the Sun Java System Web Server package, do the following:

- Ensure that the Sun Java System software is on a file system that all nodes in the cluster can access. If the Sun Java System software was delivered as a tar file, use the tar command to extract the distribution.
- Ensure that the logical host name or shared address is set up. In most cases, you set up the logical host name when you install Sun Cluster.
- Ensure that there is enough disk space for the installation. For information about the amount of disk space that the installation requires, see the Sun Java System Web Server documentation.
- Determine whether to run Sun Cluster HA for Sun Java System Web Server as a failover or a scalable service.
- Determine where you want to install the application and data files. You can install locally or globally.
- If you plan to run multiple instances of the Sun Java System Web Server data service or multiple data services on the same node, determine a unique network address and port number for each instance.
- Ensure that you have the CD that contains the data service.

Installing Sun Cluster HA for Sun Java System Web Server

Sun Java System Web Server takes approximately 10 minutes to install.

If you exit SunPlex Manager or click the Back button in your Web browser after you begin the installation, you are disconnected from the installation. This disconnection can result in an incomplete installation because of insufficient information or an unresolved error message.

To clean up an incomplete installation, remove the application files and resources and resource groups that were created.

The following table describes the information you must provide during installation:

Field | Description
--- | ---
Administrative Server Port | The port used by the Sun Java System Administrative Server. By default, the value of this field is 8888.
Administrative Server Password | The password used to access the administrative server port.
Web Server Port | The port on which the Web server accepts requests. Typical values are 80 or 8080. If you are running the Sun Cluster HA for Sun Java System Web Server service and another HTTP server, and if they use the same network resources, configure the servers to listen on different ports. Otherwise, a port conflict occurs between the two servers.
Source Directory for Sun Java System Installation | The directory that holds the Sun Java System software. The setup executable must be located in this directory.
Installation Directory | The directory where the binaries for the Sun Java System Web Server application are installed. Warning: If one or more binaries for the Sun Java System Web Server application are located in this directory, the installation fails.
Root Directory for Web Pages | The directory that holds the Web pages for the Sun Java System Web Server.
Network Resource | The logical host name or shared address that is used to access Sun Java System Web Server over the network. If a logical host name is used, one Sun Java System Web Server instance runs as a failover service. If a shared address is used, multiple Sun Java System Web Server instances run as a scalable service.
Resource Name | The name of the Sun Java System Web Server resource that is created. This name must be unique within the cluster.
Resource Group Name Used for a scalable resource | If a shared address is used, this field specifies the name of the resource group that is created. This resource group will hold the scalable Sun Java System Web Server resource. If a logical host name is used, the failover Sun Java System Web Server resource is placed in the same resource group as the logical host name.
Name Service | This option controls the Sun Java System Web Server address parameters, and normally matches the type of name service in use on the cluster. If you use DNS, the address is the logical host name or shared address. If you use NIS, the address is the numeric IP value that is associated with the logical host name or shared address.
Dots Demo | If you choose to install Dots Demo, SunPlex Manager installs additional Web pages on the cluster to demonstrate load balancing across the cluster.

To test the Web server, click the Web server URL.

SunPlex Manager tests Sun Cluster HA for Sun Java System and displays a confirmation window.
