Configuring PATROL Agent to operate in a cluster
Setting up PATROL to run in a UNIX 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 UNIX cluster and integrating PATROL into that environment.
Installing the application on a shared disk
Install the cluster application on a shared disk that's available to the entire cluster.
In UNIX environments, the executable can be installed on the local disk. Such an installation strategy may require additional administrative and maintenance tasks.
Installing the PATROL Agent on each cluster node
Use the same installation strategy for the PATROL Agent that you used for the cluster application.
You must have at least one agent executable installed on the node's local drive to monitor the node's operating system. If you select to install the cluster application on the local disk, you'll also have one to monitor the cluster application.
Assigning a unique port number
During agent installation on each node, assign a unique, listening port number to the PATROL Agent bound to the cluster application. If you install the agent on each node, the port must be the same across all nodes within the cluster.
Defining the PATROL cluster-specific environment variables
Create and set the PATROL variables that are specific to clusters. For more information, see Define the PATROL cluster-specific environment variables
Defining the PATROL Agent as a member of the package
Associate the PATROL Agent process with the cluster application. For more information, see Define the PATROL Agent as a member of the group.
