Manually configuring the PATROL Agent for clustering

Setting up PATROL to run in a Windows cluster environment consists of several standard tasks. The standard cluster administration tasks and the PATROL-specific tasks are described in general terms. This section provides a high-level overview of building a Windows cluster and integrating PATROL into that environment.

You can use the process defined in this section to run multiple PATROL Agent executables on your CPU based on your requirements.

Install the application on each cluster node

Install the cluster application on the local disk. The PATROL Agent executable must be installed on the local disk.

Install the PATROL Agent on each cluster node

Install the PATROL Agent on the local disk of the node. You must have two Agent instances running on the node as follows:

• One to monitor the node's operating system
• One to monitor the cluster application

Install the agent once, and include only those KMs that support the application and the operating system. For information about setting up a second agent to monitor the cluster application, see Create and register a new service for the PATROL Agent.

Assign a unique port number

During installation of the agent on each node, assign a unique, listening port number to the PATROL Agent bound to the cluster application. This port must be the same across all nodes within the cluster.

Define the PATROL cluster-specific environment variables

Create and set the PATROL Cluster-Specific variables. For more information, see Define the PATROL cluster-specific environment variables

Create and register a new service for the PATROL Agent

Set up a separate PATROL Agent process that can be bound to the cluster group. For more information, see Create and register a new service for the PATROL Agent.

Define the PATROL Agent as a member of the group

Associate the PATROL Agent process with the cluster application. For more information, see Define the PATROL Agent as a member of the group.

Letting applications outside the firewall connect to the PATROL Agent

When installing Microsoft Windows Vista or Microsoft Windows Server 2008 operating system on the PATROL Agent, you are prompted to add the PATROL Agent executable to the Windows Firewall Exception list. From the installation wizard, select yes if you want to let applications outside the firewall to connect to the PATROL Agent.
