ORA-12154:TNS:监听程序无法识别连接描述符中请求的服务--用plsql和sqlplus都连接不上数据库了

 

问题：用plsql和sqlplus都连接不上数据库了

描述：
1.oracle服务都已经启动了
2.用plsql连接数据库提示：ORA-12154:TNS:监听程序无法识别连接描述符中请求的服务
3.cmd--》sqlplus---》输入用户名和密码能登陆
4.cmd--》可以用命令导出数据库
5.在log中显示：
2010-12-08 08:32:09.921: [  OCROSD][1672]utgdv:1:could not open registry key SOFTWARE\Oracle\ocr os error 操作系统找不到已输入的环境选项。

2010-12-08 08:32:10.046: [  OCRRAW][1672]proprinit: Could not open raw device

2010-12-08 08:32:10.046: [ CSSCLNT][1672]clsssinit: error(33 ) in OCR initialization

解决办法：

改成和tnsnames.ora以及listener.ora中的一样

# listener.ora Network Configuration File: E:\oracle\product\10.2.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = E:\oracle\product\10.2.0\db_1)
