ORA-12514 TNS 监听程序当前无法识别连接描述符中请求服务

在oracle服务器Oracle安装目录（我的在C:\APP下，每个人的不一样，根据自己的情况查找）Network/admin目录下找到listener.ora 我的如下图所示

# listener.ora Network Configuration File: C:\APP\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\APP)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = ORCL)
(ORACLE_HOME = C:\APP)
(SID_NAME = ORCL)
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = onest)(PORT = 1521))
)
)

标红的为我添加的部分，ORCL为监听的实例名。

添加完成后 重启orcacle服务。
