Establishes a cluster alias node identifier for use by the local
 node.  The node-id is a DECnet node identifier that can be either
 a node-name or a node-address.  This alias permits the local node
 to be associated with a cluster node identifier common to some or
 all the nodes in a cluster, in addition to its own unique node-id.
 If this parameter is not specified, the local node is not associated
 with a cluster alias node identifier.  If a node-name is to be used
 as the alias node-id,  the node-name must previously have been
 defined in the database.
