ORA-00392 ORA-00312 错误处理

问题描述

还原回复数据库后，在open数据库时报如下错误：

SQL> alter database open RESETLOGS;
alter database open RESETLOGS
*
ERROR at line 1:
ORA-00392: log 17 of thread 1 is being cleared, operation not allowed
ORA-00312: online log 17 thread 1: '/oradata/redofile/redo17.log'

看起来是，在线日志文件online log 17 正在被清除，不允许操作。
