以resetlogs方式open数据库报错ORA-00392 ORA-00312

数据库：oracle 11.2.0.4

系统：AnolisOS 7.9

问题描述：Rman恢复后，以resetlogs方式打开数据库，报错ORA-00392、ORA-00312，如下所示：

SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-00392: log 3 of thread 1 is being cleared, operation not allowed
ORA-00312: online log 3 thread 1: '/u01/app/oracle/oradata/orcl/redo03.log'

异常原因：在线日志文件log 3正在被清除，无法open数据库.
