为了避免传说中的RAC风暴，还是将各个集群节点列出来比较合适

xman=
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.19.150)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.19.151)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.19.153)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = xman)
    )
  )
