若Oracle出现“ORA-12514: TNS:监听程序当前无法识别连接描述符中请求的服务”这个错误可以按照以下方法解决：
可以通过这个路径找到一个文本文件：
oracle\product\10.2.0\db_1\NETWORK\ADMIN\listener.ora 还一个在同路径下的tnsnames.ora文件，这两个文本中的一些信息要是这样的：
listener.ora
# listener.ora Network Configuration File: F:\oracle\product\10.2.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = F:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = F:\oracle\product\10.2.0\db_1)
(SID_NAME = orcl)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
)
)
出现“监听程序当前无法识别连接描述符中请求的服务”一般是因为缺少了上面中间位置的
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = F:\oracle\product\10.2.0\db_1)
(SID_NAME = orcl)
)
只要把它加在上面就ＯＫ了！！！！！！！！！！！！！
tnsnames.ora
# tnsnames.ora Network Configuration File: F:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(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)
)
)
