若Oracle出现“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 :
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 = d:/oracle/product/10.2.0/db_1) (PROGRAM = extproc) ) (SID_DESC = (GLOBAL_DBNAME = orcl) (ORACLE_HOME =d:/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 = D:/oracle/product/10.2.0/db_1) (SID_NAME = orcl) )
