3.6 Redundant Manager Operation Model

Redundant Manager operation is a function that increases the availability of an entire system by monitoring the system using two Managers.
Because two Managers with the same functions are used, management information is maintained by both Managers. Even if a problem occurs in one server, monitoring can continue on the other server without the need to perform any switching operations. This minimizes business shutdown time and ensures the system provides high availability.

Note

Performance information collected cannot be managed by using the agent for Agentless Monitoring function with the Redundant Manager .

Execution environment

This function is provided by Systemwalker Service Quality Coordinator Enterprise Edition. To use this function, the Manager must be Enterprise Edition, but the Agents can be either Standard Edition or Enterprise Edition.

The following example explains how a redundant Manager system is installed in a new Systemwalker Service Quality Coordinator environment.
