Windows Cluster Service Installation

The Windows Cluster Service must be installed and configured on the cluster nodes before installing the Ingres High Availability Option. The Cluster Service is a component of Windows Clustering that creates a server cluster and controls all aspects of its operation.

Cluster Administrator

Cluster Administrator is an application used to configure a cluster. It can run on any member of the trusted domain, whether the computer is a node of the cluster or not.

Verify Windows Cluster Service Installation

To verify the Windows Cluster Service installation, a system administrator can start Cluster Administrator from the Windows Start menu. Choose Start, Programs, Administrative Tools, Cluster Administrator.

Cluster Command

As an alternative to using Cluster Administrator to verify the Windows Cluster Service installation, you can use the cluster command from the Windows command prompt. Also, the command (cluster.exe) can be called from command scripts.

To verify the installation, a system administrator can use the following commands:

Command	Description
