环境:Oracle11g R2 + PL SQL Developer + SQL Plus 问题:Oracle主服务和监听器服务已经启动,使用SQL Plus能够正常连接,使用PL SQL Developer连接报次错误:ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务。如图: 解决: 打开H:\Oracle\pr

环境:Oracle 11g R2 + PL SQL Developer + SQL Plus

问题:Oracle主服务和监听器服务已经启动,使用SQL Plus能够正常连接,使用PL SQL Developer连接报次错误:ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务。如图:

解决:

打开H:\Oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN(不同机器目录可能不同)目录下的listener.ora文件,发现此文件内容如下:

  1. #listener.ora Network Configuration File:
  2. H:\Oracle\product\11.2.0\dbhome_1\network\admin\listener.ora
  3. #Generated by Oracle configuration tools.
  4. SID_LIST_LISTENER=
  5. (SID_LIST =
  6. (SID_DESC =
  7. (SID_NAME = CLRExtProc)
  8. (Oracle_HOME =H:\Oracle\product\11.2.0\dbhome_1)
  9. (PROGRAM = extproc)
  10. (ENVS ="EXTPROC_DLLS=ONLY:H:\Oracle\product\11.2.0\dbhome_1\bin\oraclr11.dll")
  11. )
  12. )
  13. LISTENER=
  14. (DESCRIPTION_LIST =
  15. (DESCRIPTION =
  16. (ADDRESS = (PROTOCOL = IPC)(KEY =EXTPROC1521))
  17. (ADDRESS = (PROTOCOL = TCP)(HOST =localhost)(PORT = 1521))
  18. )
  19. )
  20. ADR_BASE_LISTENER= H:\Oracle

修改成如下内容(注意红色部分的内容):

#listener.ora Network Configuration File:

H:\Oracle\product\11.2.0\dbhome_1\network\admin\listener.ora

#Generated by Oracle configuration tools.

SID_LIST_LISTENER=

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = ORCL)

(Oracle_HOME =H:\Oracle\product\11.2.0\dbhome_1)

(SID_NAME = ORCL)

)

(SID_DESC =

(SID_NAME = CLRExtProc)

(Oracle_HOME = H:\Oracle\product\11.2.0\dbhome_1)

(PROGRAM = extproc)

(ENVS ="EXTPROC_DLLS=ONLY:H:\Oracle\product\11.2.0\dbhome_1\bin\oraclr11.dll")

)

)

LISTENER=

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY =EXTPROC1521))

(ADDRESS = (PROTOCOL = TCP)(HOST =localhost)(PORT = 1521))

)

)

ADR_BASE_LISTENER= H:\Oracle

说明:每台电脑的Oracle安装目录和实例名不尽相同,修改此文件的ORACLE_HOME(本机Oracle安装目录)和SID_NAME应该按照你自己的设置。
