Adding, Removing and Configuring Load Distribution Domains

You add load distribution domains and session servers to a domain in the Session Server Explorer of the Administrative Console.

Session servers and management servers have different failover mechanisms. See Configuring Management Servers for Failover.

After installing Host Integrator on the first system, install subsequent servers using the Join an existing installation option. Use the management server name and password set in the first installation.

To add and edit a domain

  1. In the Administrative Console, connect to the management server cluster with the user name admin and the password set during installation or other administrative credentials set in the Administrative Console. From the Host Integrator perspective, choose Session Servers.
  2. In the Session Server Explorer tree, right-click Load Distribution Domains, and choose Add domain.

    The Add Domain dialog box displays.

  3. Type a name for the new session server load distribution domain, and click OK.

    The new domain is listed under Load Distribution Domains in the Session Server Explorer.

  4. In the Session Server Explorer, select the new domain, right-click and choose Properties.

    The properties page for this domain displays.

  5. Click Add to identify the session servers that will be used by this domain. In the Add Domain Session Server dialog box, select the session server you want to add to the domain and then enter a weight and priority.

  6. The session server has two properties associated with it; weight and priority.

    For each set of servers with the same priority, make their weight vlaues total to 100. This makes it easier to identify each server's load as a percent of the total.

For example:

With this domain setup Server A handles approximately 80% of the session requests and Server B handles approximately 20%. If Server A is unavailable, then Server B will handle 100% of the session requests. Server C will only be asked to handle a session request if both Server A and Server B are unavailable. As soon as Server A or Server B becomes available then Server C will no longer be asked to handle a session request.

Server Weight Priority
Server A 80 0
Server B 20 0
Server C 100 1
