ORA-00392ORA-00312日志正在清除故障
最近在还原Oracle数据库后open的时候碰到了ORA-00392:log3ofthread1isbeingcleared,operationnotallowed，其字面含义则是日志文件正在被清除，不允许操作。
通常情况下，当我们基于不完全恢复的时候，日志文件需要被清空，而此时是正在被清空。不是很好理解啊。下面是这个问题的解决方案。
一、故障现象
<codeclass="hljsvhdl">SQL>alterdatabaseopenresetlogs; alterdatabaseopenresetlogs * ERRORatline1: ORA-00392:log3ofthread1isbeingcleared,operationnotallowed ORA-00312:onlinelog3thread1:'/oradata/sincnet/redo03.log' --查看故障描述信息 SQL>hooerrora00392 00392,00000,"log%softhread%sisbeingcleared,operationnotallowed" //*Cause:Anoperationencounteredthisonlineloginthemiddleofbeing //cleared.Thecommandthatbegantheclearingmayhaveterminated //withoutcompletingtheclearing. //*Action:Iftheclearcommandisstillexecutingthenwaitforits //completion.Ifitterminatedthenreissuetheclearcommand,or //dropthelog. --下面的SQL语句表名3个日志文件都处于clearing状态 SQL>selectgroup#,bytes/1024/1024||'M',statusfromv$log; GROUP#BYTES/1024/1024||'M'STATUS ------------------------------------------------------------------- 150MCLEARING 350MCLEARING_CURRENT 250MCLEARING</code>
二、故障处理
