About failover

In your Network Manager environment, a failover architecture can be used to configure your system for high availability, minimizing the impact of computer or network failure.

Failover can be implemented for each of the following products and components, which can be installed when you run the Network Manager installer:
  • The Network Manager core components, including the Polling engine and Event Gateway (which embeds the root cause analysis component)
  • The NCIM topology database
  • Tivoli Netcool/OMNIbus, including the ObjectServer (for event management)
  • The Tivoli Netcool/OMNIbus Web GUI, which is installed within the Dashboard Application Services Hub server framework
    Restriction: Network Manager does not support the Dashboard Application Services Hub load balancing feature that the Tivoli Netcool/OMNIbus Web GUI does.

You must decide for which components you want to implement failover, and the number of computers required for high availability.
