ncp_virtualdomain command line options

Use the ncp_virtualdomain command to start the Virtual Domain component.

Usage considerations

Virtual Domain is used when running Network Manager with failover.

It is best practice to configure the ncp_ctrl process, the master process controller, to launch and manage Virtual Domain. You can configure the behavior of the process when it is started by using the command line options.

Example commands

The following example command starts the ncp_virtualdomain process in the domain NCOMS:

ncp_virtualdomain –domain NCOMS
