ORA-00312: online log 3 thread 1: '/opt/oracle/oradata/nuage/redo03.log'

从上面不难看出数据库无法归档.那什么原因造成的呢?通过查看了alter的日志,分析在某个时点出现了异常随后找了相关的了解下情况,主要是开发人员在不正常的情况下关闭数据库,这样一来使得在没有运行完毕的SQL语句造成数据库线程停止.知道了原因接下来就解决问题吧!

SQL> alter database clear unarchived logfile '/opt/oracle/oradata/nuage/redo03.log';
Database altered.

SQL>shutdown immediate
Database closed.
Database dismounted.

通过这次的故障给我们敲响警钟,在任何情况下都得正常的关闭数据库.
