有客户联系我们,说一个19c的库,由于产生归档较多在备份过程中把部分归档删除而导致没有备份成功,从而使得他们那边一个误操作需要恢复使用备份做不完全恢复,备份厂商进行恢复并尝试强制打开库报ORA-600 kcbzib_kcrsds_1错误
ORA-600-kcbzibz_kcrsds_1


由于客户那边使用的是CDM方式备份,可以较快的准备出来一个新环境,观察客户在应用日志过程中,文件头的scn一直不变,怀疑文件头由于begin backup冻结,对其进行dump,发现确实做了hot backup操作,而且没有end backup
scn
begin-backup

由于缺少归档,不完全恢复没有成功,begin backup 也无法正常结束,对于这种情况,先尝试调整到文件头最大的scn值,尝试打开库

打开库失败,只能找出来数据库最大的block中最大scn,然后调整文件头scn的值,实现数据库open

一个12.2.0.1的库由于某种原因引起的双机切换,导致数据库无法正常mount

这个错误相对比较明显,是由于ctl异常导致,通过重建ctl,然后mount库,利用Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)脚本进行检测发现所有数据文件头的checkpoint 信息被冻结在 2024-11-29 19:00:29 (scn 2112302221),分析alert日志数据库在此后20天中正常提供服务,业务运行都正常,客户反馈在这个冻结checkpoint信息的时间点,使用备份一体机发起过备份,之后就没有再备份了.
当时急着恢复数据库,没有对文件头进行dump不然应该可以发现类似begin backup的信息,类似这样(测试环境重现):

由于raid卡bug故障,导致文件系统异常,从而使得数据库无法正常启动,客户找到我之前已经让多人分析,均未恢复成功,查看alert日志,发现他们恢复的时候尝试resetlogs库,然后报ORA-600 kcbzib_kcrsds_1错误

然后他们又重建了ctl,通过Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)检查,发现几个问题:
1. PDB$SEED不在该库记录中(由于该pdb中无业务数据,可以忽略)

2. 部分文件resetlogs 信息不正确(应该是对部分文件offline或者重建ctl的时候没有带上他们)

接手该库进行恢复,尝试resetlogs该库

通过分析这两个错误

[oracle@ora19c:/home/oracle]$ oerr ora 65088
65088, 00000, "database open should be retried"
// *Cause:   An inconsistency between the control file and the data dictionary
//           was found and fixed during the database open. The database open
//           needs to be executed again.
// *Action:  Retry the database open.
//
[oracle@ora19c:/home/oracle]$ oerr ora 01209
01209, 00000, "data file is from before the last RESETLOGS"   
// *Cause:  The reset log data in the file header does not match the   
//         control file. If the database is closed or the file is offline,  
//         the backup is old because it was taken before the last ALTER   
//         DATABASE OPEN RESETLOGS command. If opening a database that is   
//         open already by another instance, or if another instance just   
//         brought this file online, the file accessed by this instance is 
//         probably a different version. Otherwise, a backup of the file 
//         probably was restored while the file was in use.   
// *Action: Make the correct file available to the database. Then, either open
//         the database, or execute ALTER SYSTEM CHECK DATAFILES.  

ORA-65088参见官方:ORA-65088 while opening DB with resetlogs for multi-tenant DB in 12.2 (Doc ID 2449591.1),应该不是一个技术问题(由于重建ctl+resetlogs导致)
ORA-01209: data file is from before the last RESETLOGS 这个错误,可以简单理解resetlogs的信息比数据文件的checkpoint信息新,对于这种情况,以及结合上述的部分文件resetlogs信息不一致问题,索性直接使用m_scn小工具对其进行批量
m_scn


再次使用Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)检查,确认resetlogs 问题修复
resetlogs

然后顺利打开数据库,并导出数据,完成本次恢复任务

*****************************************************************
An internal routine has requested a dump of selected redo.
This usually happens following a specific internal error, when
analysis of the redo logs will help Oracle Support with the
diagnosis.
It is recommended that you retain all the redo logs generated (by
all the instances) during the past 12 hours, in case additional
redo dumps are required to help with the diagnosis.

官方关于kcbzib_kcrsds_1从解释只有:Bug 31887074 – sr21.1bigscn_hipu3 – trc – ksfdopn2 – ORA-600 [kcbzib_kcrsds_1] (Doc ID 31887074.8)
ksfdopn2


虽然关于ORA-600 [kcbzib_kcrsds_1],oracle官方没有给出来解决方案,其实通过以往大量的恢复案例和经验中已经知道,这个错误解决方案就是修改oracle scn的方法可以绕过去,以前有过一些类似恢复案例:
