IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
IBM Tivoli Monitoring cluster setup
A basic cluster setup includes two computers that participate as nodes in the cluster. Each computer must have two Network Interface Cards (NICs): one for the heartbeat function between the two computers, the other for public access.
The Tivoli Monitoring requirements for the cluster server are:
- A shared persistent data storage for the IBM Tivoli Monitoring installation directory and for any component-specific data.
- A virtual IP address to be assigned to the component that runs on the cluster.
Some important characteristics of a clustered IBM Tivoli Monitoring setup include:
- The shared persistent storage and virtual IP Address must be available before you can install IBM Tivoli Monitoring; also, the node where Tivoli Monitoring is installed must own these resources.
- Install an IBM Tivoli Monitoring component (such as the hub monitoring server) only once on the first node of the cluster (on the shared directory); then, configure it on the second node. In the Windows environment, this means that the IBM Tivoli Monitoring registry keys must be replicated to the second node.
- The IBM Tivoli Monitoring component must be bound to the virtual IP address such that the infrastructure's other IBM Tivoli Monitoring components can reach it no matter which node it is running on. To do this, set the network interface where the component listens on.
- Only one instance of the component can be active at a time.
- When IBM Tivoli Monitoring is running under the cluster, its services cannot be automatically started. Likewise, its services cannot be directly started or stopped through the command line or through the Manage Tivoli Enterprise Monitoring Services GUI. Instead, the services must be controlled through the cluster manager.
The following table shows the high-level steps required to set up the main Tivoli Monitoring components running in a cluster.
