A service name is a designation by which services in the StreamBase Runtime fabric are addressed. With most epadmin commands, you must provide a servicename= parameter to identify the participant of interest.

When you install a node with an epadmin install node command, you include a nodename= parameter. Thereafter, that declared node name is used as the service name to address the node. For example:

epadmin install node nodename=B.sbuser application=...
epadmin servicename=B.sbuser start node
epadmin servicename=B.sbuser stop node
epadmin servicename=B.sbuser remove node

A cluster name can also be a service name, when used in a command addressed to all nodes in a cluster. For example:

epadmin install node nodename=A.sbuser application=...
epadmin install node nodename=B.sbuser application=...
epadmin install node nodename=C.sbuser application=...
epadmin servicename=sbuser start node
