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:

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。
