Cluster Properties: General Tab
Cluster Properties Dialog Box (General Tab)

Description

You displayed this dialog box by right clicking on a SmartCluster icon and selecting Properties…Use this box to see a listing of all current SmartCluster members. That is, all the Web servers that make up the selected SmartCluster.

1.	Type -- This indicates that the type of property dialog box you are looking at is for a SmartCluster.

2.	Cluster Members -- List of all Web servers that are currently members of their SmartCluster.


Create NewCluster Dialog Box

Description

Use this dialog box to create a new SmartCluster.

1.	Cluster Name -- Unique SmartCluster name for the new SmartCluster.

2.	Server Name -- Name of one of the IIS servers you will be adding to the new SmartCluster. Make sure to include the FQHN (fully qualified host name) for the server you entered in the hosts file or are registered with DNS. This Server becomes the default Admin Manager for the SmartCluster.

3.	License Key -- This field specifies the current license key specified for this SmartCluster. You can update the license key by modifying the "License Key" field in Cluster Properties · Administration Tab. If updating, the Web server acting as the Administrative manager must be accessible.


Cluster Properties: Administration Tab
SmartCluster Properties Dialog Box (Administration Tab)

Description--

Use this tab to select your SmartCluster Administrative Manager, modify the existing license key, and enable or disable Bright Tiger Authentication, and enable or disable session aware load balancing.

1.	Administrative Manager -- This field lists the current administrative manager. In each Bright Tiger SmartCluster, one of the Web servers is designated as the administrative manager. When a SmartCluster is created, the first server added becomes the default administrative manager. You can change the designated administrative manager if you need to delete the server that's currently the administrative manager. The administrative manager is responsible for allowing other Web servers to be added and deleted from the SmartCluster.

2.	License Key -- This field specifies the current license key for this SmartCluster. The user can update the license key by modifying this field. The Web server acting as the administrative manager must be accessible in order to change this field.

 Authentication Mode -- These fields let you specify the mode of Authentication you want to implement on a per-SmartCluster basis.

The modes include --

No Authentication

When Authentication is turned off on a specific SmartCluster, any ClusterCATS Explorer can add that SmartCluster to their Cluster Manager view. Once the SmartCluster is added, you will have unrestricted access to the content in that SmartCluster.

Windows NT Domain Authentication

Note: Windows NT Domain Authentication does not work on ClusterCATS on Windows 95. Before you can enable NT Domain Authentication on any specific SmartCluster, you must create a special global group with a name in the form of, "BT_Clustername" within that domain.

You or the domain administrator can do this through the standard Windows NT User Manager system management utility. Once you create a "BT_Clustername" group, any of the members you add to that group are authenticated to view the SmartCluster. All members of the SmartCluster must be from the same Windows NT Domain unless a trust relationship has been set-up by the system administrator. A “BT_Clustername” global group must exist in the domain from which the ClusterCATS Explorer is executed. ClusterCATS Explorer determines what servers exist in which NT Domain by communicating with any Windows NT Domain controller for the domain. The list of servers that exist in the Windows NT Domain can be viewed by looking at the Network Neighborhood Windows NT utility. If no trust relationship exists, then SmartCluster members must be from the same Windows NT Domain.

Cluster/Server-based Local-User Authentication

In the Authentication field, select Local User. Click on OK. Local User authentication for the selected cluster is enabled. Only authorized administrators can add the cluster to their ClusterCATS Explorer view.

Make sure all authorized users for Local User Authentication have an account on each machine running the IIS server and are listed in a local group with the name “BT_clustername" where the cluster name is name of the cluster. Alternatively, authorized users can also be administrators listed in the Administrator's Group (on each machine running the IIS server).

4.	Username --  Username of authorized server account

5.	Password --  Password for the account

6.	Remember Box -- Click here if you want Bright Tiger to remember the account password between sessions and not prompt you the next time you added a SmartCluster to your view.

7.	Enable Session-Aware Load Balancing  — When this feature is enabled, the ClusterCATS software only load balances users off the current Web Server when the user is establishing a new session. A new session is defined as a user typing in a URL, using a bookmark, or by following a link from another site. Once the session is established the user will not be load balanced off of that Web Server.

This feature is an alternative to the "Do not redirect on server busy" found in the folder property box.

Server Properties Dialog Box (Access Tab)

Description

The server properties dialog box is displayed when you right click on a server icon and select, Properties…. The Access tab provides the following information.

1.	Current Status -- This field indicates whether the selected server is busy, restricted, available, or unavailable.

2.	Restriction Status -- This field allows you to restrict or un-restrict a Web server. Select one state or the other. When a Web server is in the restricted state any user requesting a URL on this Web server will be redirected to a different Web server in the SmartCluster.

3.	Load Balancing -- Turn on load balancing here. Number is the percentage of the load at which the server will start redirecting all requests to other SmartCluster members.  A value of 0% redirects all the HTTP requests, a value of 100% disables load balancing.

4.	Gradual Redirection  -- Turn on gradual redirection here. Number is the percentage of load at which the server will start gradually redirecting some requests to other servers in the SmartCluster.
