Specifies whether the local node is willing to accept incoming
 requests directed to the alias node identifier specified for
 the local node.  The alias node identifier is described under the
 ALIAS NODE parameter.  There are two options for ALIAS INCOMING:

          ENABLED     Specifies that the local node will accept
                      incoming connect requests directed to the alias
                      node identifier.  This is the default if an
                      alias node identifier has been specified.

          DISABLED    Specifies that the local node will not
                      accept the incoming connect requests
                      directed to the alias node identifier.
