ORA-00392ORA-00312日志正在清除故障

这篇文章主要介绍了ORA-00392ORA-00312日志正在清除故障的相关资料,需要的朋友可以参考下

最近在还原Oracle数据库后open的时候碰到了ORA-00392: log 3 of thread 1 is being cleared, operation not allowed,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

 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: '/oradata/sincnet/redo03.log' -- 查看故障描述信息 SQL> ho oerr ora 00392 00392, 00000, "log %s of thread %s is being cleared, operation not allowed" // *Cause: An operation encountered this online log in the middle of being // cleared. The command that began the clearing may have terminated // without completing the clearing. // *Action: If the clear command is still executing then wait for its // completion. If it terminated then reissue the clear command, or // drop the log. --下面的SQL语句表名3个日志文件都处于clearing状态 SQL> select group#,bytes/1024/1024||'M',status from v$log; GROUP# BYTES/1024/1024||'M' STATUS ---------- ----------------------------------------- ---------------- 1 50M CLEARING 3 50M CLEARING_CURRENT 2 50M CLEARING

二、故障处理

 下面直接执行clear logfile 命令 SQL> ALTER DATABASE CLEAR LOGFILE GROUP 1; Database altered. SQL> ALTER DATABASE CLEAR LOGFILE GROUP 2; Database altered. SQL> ALTER DATABASE CLEAR LOGFILE GROUP 3; Database altered. --再次查看状态,此时状态显示为常见的几种正常状态 SQL> select group#,bytes/1024/1024||'M',status from v$log; GROUP# BYTES/1024/1024||'M' STATUS ---------- ----------------------------------------- ---------------- 1 50M UNUSED 3 50M CURRENT 2 50M UNUSED --再次尝试open resetlog,依旧错误,实例终止,需要upgrade SQL> alter database open resetlogs; alter database open resetlogs * ERROR at line 1: ORA-01092: ORACLE instance terminated. Disconnection forced ORA-00704: bootstrap process failure ORA-39700: database must be opened with UPGRADE option Process ID: 30553 Session ID: 1217 Serial number: 3 --查看是否存在pmon进程 SQL> ho ps -ef|grep pmon oracle 30589 30440 0 16:02 pts/1 00:00:00 /bin/bash -c ps -ef|grep pmon oracle 30591 30589 0 16:02 pts/1 00:00:00 grep pmon --Author : Leshami --Blog : http://blog.csdn.net/leshami --下面尝试upgrade,因为当前基于一个11.2.0.1的备份恢复到11.2.0.4,所以需要upgrade SQL> startup upgrade; ORA-24324: service handle not initialized ORA-01041: internal error. hostdef extension doesn't exist SQL> SQL> exit Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing options [oracle@10134569 DBSRV]$ sqlplus / as sysdba SQL*Plus: Release 11.2.0.4.0 Production on Wed Feb 24 16:03:15 2016 Copyright (c) 1982, 2013, Oracle.
