我的目标是从OS X机器连接到Oracle 9i实例.我按照这里的设置说明进行了操作,没有错误(最终).但是,我发现sqlplus无法连接:

[ ethan@gir ~ ]$ sqlplus xxx/yyy@zzz

ERROR:
ORA-12170: TNS:Connect timeout occurred

Enter user-name: xxx
Enter password: 
ERROR:
ORA-12162: TNS:net service name is incorrectly specified

Enter user-name:

我的tnsnames.ora档案......

zzz =
  (DESCRIPTION = 
    (ADDRESS_LIST =
      (ADDRESS =
        (PROTOCOL = TCP)
        (HOST = dbhost)
        (PORT = 1521))
    )
  (CONNECT_DATA =
    (SERVICE_NAME = zzz)
  )
)
