tnsping ORCL错误信息：

Used parameter files:

Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = zjj-redhat6)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl)))
TNS-12545: Connect failed because target host or object does not exist

---------------------

tnsnames.ora文件内容

ORCL =
  (DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = zjj-redhat6)(PORT = 1521))
  (CONNECT_DATA =
  (SERVER = DEDICATED)
  (SERVICE_NAME = orcl)
  )
  )


LISTENER_ORCL = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))


------解决方案--------------------
写成localhost则只有本机好用，远程访问全都不好用。
建议用IP地址，在服务器主机上先配置好，然后copy， listner.ora和tns.ora到各个客户端的相应目录下。
