解决oracle数据库“监听程序当前无法识别连接描述符中请求的服务”
今晚搞了几个小时的oracle配置，现在终于连上了，同时也发现好多人每次重装系统后都得重装oracle，现将我如何处理这一类问题的方法分享如下，嘿嘿，屡试不爽的，更重要的是不用修改ip，直接用本地连接localhost，不论是否联网都可以这样配置！
我的oracle安装路径在F盘的app文件夹下，
首先找到F:\app\Administrator\product\11.1.0\db_1\NETWORK\ADMIN下的listener.ora和tnsnames.ora这两个文件，用记事本打开就可以
用下面的这些代码替换listener.ora中原有的代码
注：路径要是自己的安装路径
# listener.ora Network Configuration File: F:\app\Administrator\product\11.1.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = F:\app\Administrator\product\11.1.0\db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = F:\app\Administrator\product\11.1.0\db_1)
(SID_NAME = orcl)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
)
# tnsnames.ora Network Configuration File: F:\app\Administrator\product\11.1.0\db_1\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
用下面的这些代码替换tnsnames.ora 中原有的代码
# tnsnames.ora Network Configuration File: F:\app\Administrator\product\11.1.0\db_1\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
替换完成之后重启oracle数据库服务就可以了
