2.6 Manager redundancy modelIn this model, two Managers are used to manage the same system. This means that if one node fails, it is possible to continue management operations by switching to the other node.
Even if one Manager cannot be used due to a network fault, etc., this system permits the Manager connected to a functioning network to take over management operations. This differs from the redundancy that is achieved using a cluster system.
Note
If Agent functions are used on Managers, performance information collected by one Manager cannot be used by another Manager.
When an Enterprise Manager is used as the host server of Managers in a redundant configuration, a separate instance of Enterprise Manager must be provided for each Manager.
When performance information is managed by using the agent for Agentless Monitoring function on each Managers in a redundant configuration, the value of the performance data might not be corresponding because of the difference of the collected timing.
