Oracle数据库备份导出时,报错:ORA-12514解决
Oracle数据库备份导出时,报错:ORA-12514解决
连接Oracle 10g错误:ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求
解决方法: 1. 打开<OracleHome>/network/admin/listener.ora文件,找到: SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = D:\oracle\product\10.2.0\db_1) (PROGRAM = extproc) ) ) 2. 添加: (SID_DESC = (GLOBAL_DBNAME = ORACLE) (ORACLE_HOME = D:\oracle\product\10.2.0\db_1) (SID_NAME = ORACLE) ) 3. 最后变成: 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) ) )
注意:不能添加(PROGRAM = extproc)
4. 保存文件,重启服务中的TNSListener,OK!
