Controlfile sequence number

这个是一例子客户数据库运行过程中突然报:The controlfile header block returned by the OS has a sequence number that is too old.然后数据库无法正常启动的数据库恢复case
以前处理过一些类似case:Controlfile sequence number in file header is different from the one in memory
故障现象
alert日志中报The controlfile header block returned by the OS has a sequence number that is too old.错误，然后数据库crash

********************* ATTENTION: ******************** 
 The controlfile header block returned by the OS
 has a sequence number that is too old. 
 The controlfile might be corrupted.
 PLEASE DO NOT ATTEMPT TO START UP THE INSTANCE 
 without following the steps below.
 RE-STARTING THE INSTANCE CAN CAUSE SERIOUS DAMAGE 
 TO THE DATABASE, if the controlfile is truly corrupted.
 In order to re-start the instance safely, 
 please do the following:
 (1) Save all copies of the controlfile for later 
     analysis and contact your OS vendor and Oracle support.
 (2) Mount the instance and issue: 
     ALTER DATABASE BACKUP CONTROLFILE TO TRACE;
 (3) Unmount the instance. 
 (4) Use the script in the trace file to
     RE-CREATE THE CONTROLFILE and open the database. 
*****************************************************
USER (ospid: 15912): terminating the instance

这个错误比较明显是由于控制文件的sequence number比较老导致，出现这种问题，一般是由于io过慢，或者底层不稳定（比如虚拟化平台，文件系统异常，硬件不稳定等）导致（官方参考文档：The controlfile header block returned by the OS has a sequence number that is too old.）

尝试重启数据库报ORA-01207错误

该错误的官方解释

[oracle@xifenfei.com ~]$ oerr ora 1207
01207, 00000, "file is more recent than control file - old control file"
// *Cause:  The control file change sequence number in the data file is 
//         greater than the number in the control file. This implies that
//         the wrong control file is being used. Note that repeatedly causing
//         this error can make it stop happening without correcting the real
//         problem. Every attempt to open the database will advance the
//         control file change sequence number until it is great enough.
// *Action: Use the current control file or do backup control file recovery to 
//         make the control file current. Be sure to follow all restrictions 
//         on doing a backup control file recovery.

由于数据文件比控制文件更新，导致该问题，通过查询v$datafile_header发现更多类似异常文件(可以使用Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)收集信息）

alert日志文件中也有明显的写错日志信息

这些二进制内容和监听日志内容被写入到了alert日志中，证明当时文件系统或者操作系统甚至更底层出现了异常，这个客户是运行在云平台上的，具体运营需要平台厂商才能分析

故障处理
重建控制文件并进行recover

第 1 行出现错误:

数据库启动报ORA-600 2662错误，这个是典型的文件头scn过小的问题,通过自研小工具Patch_SCN可以快速解决，以前类似文章:

标题：Controlfile sequence number in file header is different from the one in memory

最近一段时间遇到多个客户类似如下错误,由于某种原因导致rac两个节点oracle实例一段时间之后就crash,然后重启,系统非常不稳定,严重影响业务使用,一个节点alert日志有类似日志

该错误在mos,互联网上没有任何信息,不过在alert日志中发现类似信息

Mon Jun 06 23:03:58 2022
Error: Controlfile sequence number in file header is different from the one in memory
       Please check that the correct mount options are used if controlfile is located on NFS

初步判断可能和这个错误有关系,解决相关问题后,尝试open库

ORA-01216: thread 2 is expected to be disabled after CREATE CONTROLFILE

SQL> !oerr ora 01216
01216, 00000, "thread %s is expected to be disabled after CREATE CONTROLFILE"
// *Cause:  A thread that was given during CREATE CONTROLFILE is enabled, but
//          the datafiles indicate that it should be disabled.  This is
//          probably because the logs supplied to the CREATE CONTROLFILE
//          are old (from before the disabling of the thread).
// *Action: This thread is not required to run the database.  The CREATE
//          CONTROLFILE statement can be reissued without the problem thread,
//          and, if desired, the thread can be recreated after the database
//          is open.

ORA-01216这个错误比较也比较少见,但是感觉和thread有关系,大概的意思是thread 被disable了

SQL> select thread#,STATUS FROM V$THREAD;

   THREAD# STATUS
---------- ------------------
         1 CLOSED
         2 CLOSED

通过人工强制把thread个open,然后数据库启动成功

SQL> select thread#,status from v$thread;

   THREAD# STATUS
---------- ------------------
         1 OPEN
         2 CLOSED

SQL> alter database open;

Database altered.

然后启动thread 2,open 第二个节点
