Stopping a node means to stop the running EventFlow or LiveView fragments in the node, and thus to stop processing tuples sent to any of a fragment's Input Streams. Stop a running fragment node with a command like the following:
epadmin servicename=A.sbuser stop node
Stopped nodes can be restarted with another epadmin start node command. This resumes processing of incoming tuples.
Nodes installed and started at the command line show up in the Clusters view of StreamBase Studio, and in the output of an epadmin display services command.
