ORA-12514:TNS:监听程序当前无法识别链接描述符中请求的服务

RA-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 Configuration File: d:oracleproduct10.2.0db_workadminlistener.ora # Generated by Oracle configuration tools. SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = d:oracleproduct10.2.0db_1) (PROGRAM = extproc) ) (SID_DESC = (GLOBAL_DBNAME = ORCL) (ORACLE_HOME = d:oracleproduct10.2.0db_1) (SID_NAME = ORCL) ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521)) (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0)) ) ) 在监听配置文件里加入上面中间的那部分，然后重启监听服务： (SID_DESC = (GLOBAL_DBNAME = ORCL) (ORACLE_HOME = d:oracleproduct10.2.0db_1) (SID_NAME = ORCL) )
