解决 ERROR - ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务
服务器莫名其妙的报这个错，之前一直正常，从google获取解决方案，解决之，记录如下：
1. Open the ""<OracleHome>/network/admin/listener.ora" file in the host,and you will see: SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = D:\oracle\product\10.2.0\db_1) (PROGRAM = extproc) ) ) 2. Add the following lines after the 7th line in the above (SID_DESC = (GLOBAL_DBNAME = ORACLE) (ORACLE_HOME = D:\oracle\product\10.2.0\db_1) (SID_NAME = ORACLE) ) 3. At last the content of the file become to the following section: 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 = ORACLE) (ORACLE_HOME = D:\oracle\product\10.2.0\db_1) (SID_NAME = ORACLE) ) ) 4. Save the file and restart the TNSListener service in the host. That's OK!?
