ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务

在安装完Oracle10g后，使用PL/SQL工具连接，提示如下的问题： ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务解决办法是手动修改监听配置文件： # listener.ora Network ConfigurationFile: d:\oracle\product\10.2.0\client_1\network\admin\listener.ora

# GeneratedbyOracle configuration tools.

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = d:\oracle\product\10.2.0\client_1)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = ORCL)

(ORACLE_HOME = G:\oracle\product\10.2.0\db_1)

(SID_NAME = ORCL)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))

(ADDRESS = (PROTOCOL = IPC)(KEY= EXTPROC0))

)

) 其中红色粗体部分是添加部分。 以上是在一台机器上既安装了Oracle服务器，又安装了客户端的情况。 下面是仅仅在一台机器上安装了服务器，并且是在服务器本机上安装PLSQL使用Oracle数据库的情况： # listener.ora Network Configuration File: E:\oracle\product\10.2.0\db_1\network\admin\listener.ora
