监听文件内容为

(SID_LIST =

   (ORACLE_HOME = /oracle/product/10.2.0)

   (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
   )
)

oracle 客户端为win7 旗舰版，32位，tnsnames.ora文件内容如下

DB_192.168.11.201 =
(DESCRIPTION =
   (ADDRESS_LIST =
   (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.11.201)(PORT = 1521))

   (CONNECT_DATA =
   (SID = db_local)
   (SERVER = DEDICATED)

  DB_192.168.11.252 =

   )
   (CONNECT_DATA =
   (SID = db)
   (SERVER = DEDICATED)
   )
)

使用tnsping命令检测正常
C:\Users\lich>tnsping db_local

已使用的参数文件:
E:\oracleclient\network\admin\sqlnet.ora

已使用 TNSNAMES 适配器来解析别名
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)
(HOST = 192.168.11.33)(PORT = 1521))) (CONNECT_DATA = (SID = db_local) (SERVE
R = DEDICATED)))
OK (20 毫秒)
但是
使用sqlplus连接时提示不能识别的SID

请问这个是怎么回事?

创建密码文件，然后把*.remote_login_passwordfile值修改为'EXCLUSIVE'，就可以了
谢谢！ ...

试一试system用户

system用户也是一样的错误提示，没有密码文件，因为我在参数文件里面设置为
*.remote_login_passwordfile='NONE'
这个应该没有问题吧?

用动态侦听吧

把listener.ora文件删除了

按你说的这个方法，我把服务器端监听停了后，把listener.ora重命名，然后lsnrctl sart,lsnrctl reload,运行lsnrctl status，显示内容如下
$ lsnrctl status

此时在客户端连接时，也提示权限不够，

你的listener中未注册任何服务，静态注册也没有设置任何服务，远程连接遇到ORA-12505 不是再正常不过的 ...

谢谢刘大指点，现在将服务器端监听文件修改为
SID_LIST_LISTENER =
(SID_LIST =
   (SID_DESC =
   (SID_NAME = PLSExtProc)
   (ORACLE_HOME = /oracle/product/10.2.0)
   (PROGRAM = extproc)
   )
   (SID_DESC =
   (GLOBAL_DBNAME = db)
   (ORACLE_HOME = /oracle/product/10.2.0)
   (SID_NAME = db_local)
   )
)

LISTENER =
(DESCRIPTION_LIST =
   (DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.11.33)(PORT = 1521))
   )
)
说明：数据库 DB_name为db，instance_name为db_local
重新启动监听，查看监听状态
$ lsnrctl status

客户端tnsnames.ora文件为
DB_LOCAL =
(DESCRIPTION =
   (ADDRESS_LIST =
   (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.11.33)(PORT = 1521))

再次在客户端连接，提示权限不够

请问我是不是还有哪个地方设置不正确?
