最近在還原Oracle數(shù)據(jù)庫(kù)后open的時(shí)候碰到了ORA-00392: log 3 of thread 1 is being cleared, operation not allowed,其字面含義則是日志文件正在被清除,不允許操作。
通常情況下,當(dāng)我們基于不完全恢復(fù)的時(shí)候,日志文件需要被清空,而此時(shí)是正在被清空。不是很好理解啊。下面是這個(gè)問(wèn)題的解決方案。
一、故障現(xiàn)象
code class="hljs vhdl">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語(yǔ)句表名3個(gè)日志文件都處于clearing狀態(tài)
SQL> select group#,bytes/1024/1024||'M',status from v$log;
GROUP# BYTES/1024/1024||'M' STATUS
---------- ----------------------------------------- ----------------
1 50M CLEARING
3 50M CLEARING_CURRENT
2 50M CLEARING/code>
二、故障處理
code class="hljs vhdl">code class="hljs vhdl">下面直接執(zhí)行clear logfile 命令
SQL> ALTER DATABASE CLEAR LOGFILE GROUP 1;
Database altered.
SQL> ALTER DATABASE CLEAR LOGFILE GROUP 2;
Database altered.
SQL> ALTER DATABASE CLEAR LOGFILE GROUP 3;
Database altered.
--再次查看狀態(tài),此時(shí)狀態(tài)顯示為常見(jiàn)的幾種正常狀態(tài)
SQL> select group#,bytes/1024/1024||'M',status from v$log;
GROUP# BYTES/1024/1024||'M' STATUS
---------- ----------------------------------------- ----------------
1 50M UNUSED
3 50M CURRENT
2 50M UNUSED
--再次嘗試open resetlog,依舊錯(cuò)誤,實(shí)例終止,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

--查看是否存在pmon進(jìn)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

--下面嘗試upgrade,因?yàn)楫?dāng)前基于一個(gè)11.2.0.1的備份恢復(fù)到11.2.0.4,所以需要upgrade
SQL> startup upgrade;
