10G client连接数据库

tnsnames.ora文件中的名字一定要顶格写（前面不留空格），不然连接时会如下报错。

已使用的参数文件:
F:\oracle\product\10.2.0\client_1\network\admin\sqlnet.ora
TNS-03505: 无法解析名称
C:\Users\Administrator>

错误：
   YCRDBA =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.2.0.10)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ycr.ouc.cn)
    )
  )

正确：
YCRDBA =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.2.0.10)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ycr.ouc.cn)
    )
  )
