2.7 Cluster System Operation ModelThe management mechanism provided by a Manager can be operated in a cluster system. This improves the availability of management operations because if a problem develops on one node, operations can continue on the remaining normal node.
Cluster system operation and corresponding installation types
Enterprise Manager
An Enterprise Manager can be used in cluster configurations.
Manager
A Manager can be used in cluster configurations.
Proxy Manager
The servers making up a cluster system can be monitored individually.
Agent for Business
The servers making up a cluster system can be monitored individually.
Agent for Server
The servers making up a cluster system can be monitored individually.
Agent for Agentless Monitoring
The servers making up a cluster system can be monitored individually. To do so, they must be able to communicate with the physical IP address of each server.
Note
When collecting the performance information of Managers or Enterprise Managers that make up a cluster system, performance information cannot be collected at the standby node.
If an Agent for Server, Agent for Business or Proxy Manager is installed on servers making up a cluster system, each of the servers in the cluster system is monitored individually. For this reason, performance information cannot be collected from middleware and other software that is not running on the standby node.
