ORA-00392 ORA-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: 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

--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;
