ORA-600 krhpfh_03-1210故障处理

发表于 2024 年 8 月 26 日 由 惜分飞

rac数据库多个节点均处于open状态,数据查询正常,但是应用入库有些时候会失败报类似ORA-01187: cannot read from file because it failed verification tests错误：
ora-01187

故障最初原因是由于有坏盘,换盘之后,有两个节点数据实例crash

但是数据库人工启动成功,查询所有数据文件均处于online状态

可是有部分入库进程非常慢大量等待在enq:HW – contention

File 1399 not verified due to error ORA-01122

基于这种情况,初步判断：
1. 是由于该集群本身多节点(6个节点),只要有节点是open状态,其他节点关闭再启动依旧可以正常启动,但是无法写入数据到报ORA-01207错误的数据文件中(可以读取数据).
2. 如果所有节点关闭关闭,然后数据库无法正常启动会报ORA-01207: file is more recent than control file错误

这样的情况,根据以往经验,ORA-01207: file is more recent than control file通过重建ctl即可恢复,先关闭所有节点,然后尝试启动一个节点

和预期的一样,重试重建ctl,然后数据库报ORA-00600 [krhpfh_03-1210]错误

ORA-01110: data file 1399: '+DATA/xifenfei99.dbf'

这里的提示是有fhcpc和fhccc值不对导致,通过bbed查看相关值

BBED> set file 1399
	FILE#          	1399

BBED> p kcvfhccc
ub4 kcvfhccc                                @148      0x00043227 ===>274983(10进制)

报错比较明显通过bbed修改这两个值

分布式存储故障导致数据库无法启动故障处理

发表于 2024 年 5 月 11 日 由 惜分飞

国内xx医院使用了国外医疗行业龙头的pacs系统,由于是一个历史库,存放在分布式存储中,由于存储同时多个节点故障,导致数据库多个文件异常,数据库无法启动,三方维护人员尝试通通过rman归档进行应用日志,结果发现日志有损坏报ORA-00354 ORA-00353,无法记录恢复,希望我们给予支持

接手故障之后,通过尝试恢复发现除该错误之外,还有ORA-600 4552之类错误
ORA-600-4552

跳过这些异常文件恢复,最终确认异常文件有如下部分
20240511223413
这些文件由于日志无法正常应用(有日志损坏无法应用，有日志和数据文件block不匹配导致无法应用),这样的情况直接通过自研的Oracle Recovery Tools小工具直接修改文件头信息
orarecovery
然后尝试OPEN数据库结果报ORA-1207
ORA-1207
对于这个故障可以通过rectl或者using backup ctl方式处理,然后open数据库成功
20240510224845
由于该系统是历史库,不会有新业务写入,通过对异常表和索引进行处理之后,客户测试业务可以正常访问,完成本次恢复

ORA-1200/ORA-1207数据库恢复

发表于 2023 年 11 月 14 日 由 惜分飞

由于系统性能问题或者底层io问题,数据库alert日志报一下控制文件损坏错误然后crash掉

********************* 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.
