ORA-600 ktubko_1 恢复

oracle 12.2的rac库,pdb在open成功之后,没过多久会自动crash掉,主要报错ORA-600 ktubko_1

因为有smon报的ORACLE Instance orcl1 (pid = 44) – Error 600 encountered while recovering transaction (12, 1) on object xxx这种比较明显错误,基本上可以定位是undo问题.对undo异常事务进行处理,数据库顺利open,并且稳定不再crash,然后对异常对象进行处理(当然也可以逻辑迁移)

在oracle 12.2到18.14的rac环境的cdb库中,如果节点sga大小不一致,而且有一个节点sga大于128G,就可能出现该问题,敬请注意

标题：一键修改Oracle SCN工具升级(patch scn)

前段时间开发了基于内存修改的patch scn小程序（修改oracle scn小工具(patch scn)），用来修改oracle数据库scn,实现快速调整oracle scn的功能（特别是在一些恢复的时候很有用）,最近对其功能进一步完善，扩展了通过修改oracle controlfile实现调整scn功能,简单测试如下

.mkp和.Elbie勒索加密数据库可恢复

联系：手机/微信(+86 17813235971) QQ(107644445)

标题：.mkp和.Elbie勒索加密数据库可恢复

最近有朋友咨询了两种win机器文件加密的oracle数据库，通过判断均可修复然后正常open库
.DBF.[5D00A5FE].[Xats@privatemail.com].mkp,可以实现数据文件数据0丢失,和强制拉库效果一样

.DBF.id[10D73871-3400].[hero77@cock.li].Elbie,每个文件丢失数据小于1M

以上两种勒索加密都可以通过Oracle数据文件勒索加密恢复工具,快速open

对于类似这种被加密的勒索的数据文件（.[Xats@privatemail.com].mkp和.[hero77@cock.li].Elbie）,我们可以实现比较好的恢复效果,如果此类的数据库(oracle,mysql,sql server)等被加密,需要专业恢复技术支持，请联系我们:

系统安全防护措施建议：
1.多台机器，不要使用相同的账号和口令
2.登录口令要有足够的长度和复杂性，并定期更换登录口令
3.重要资料的共享文件夹应设置访问权限控制，并进行定期备份
4.定期检测系统和软件中的安全漏洞，及时打上补丁。
5.定期到服务器检查是否存在异常。
6.安装安全防护软件，并确保其正常运行。
7.从正规渠道下载安装软件。
8.对不熟悉的软件，如果已经被杀毒软件拦截查杀，不要添加信任继续运行。
9.保存良好的备份习惯，尽量做到每日备份，异地备份。

存储强制拉lun导致数据库异常恢复

客户那边反馈有几个lun异常,无法正常online

通过存储工程师强制拉起来lun(清除掉了cache),但是数据库无法正常mount

可以要求保护第一现场,把asm中的数据恢复到文件系统中,然后进行恢复,由于客户是10g的环境,无法直接使用asmcmd中的cp实现此项操作,数据库也没有mount成功(无法使用rman的copy),考虑使用oracle的amdu实现此项操作需求.在拷贝过程中报AMDU-00204报错

由于部分文件不是该库的,通过进一步分析,除掉不是该库的文件,重建ctl文件成功.尝试recover数据库，报大量ORA-07445错误，由于cache丢失redo损坏导致,此类操作可能导致数据文件损坏【恢复需要谨慎,最好对数据文件做一次备份】

类似此类错误的解决方案,以前写过参考:
在数据库open过程中常遇到ORA-01555汇总
 数据库open过程遭遇ORA-1555对应sql语句补充
 Oracle Recovery Tools恢复—ORA-00704 ORA-01555故障
 使用_allow_resetlogs_corruption导致ORA-00704/ORA-01555故障
解决该问题,数据库启动正常,逻辑导出数据，导入数据完成此次恢复任务,实现绝大部分数据恢复

ORA-00316 ORA-00312故障处理

联系：手机/微信(+86 17813235971) QQ(107644445)

标题：ORA-00316 ORA-00312故障处理

数据库启动报ORA-00316,ORA-00312,无法正常启动

通过Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)分析,确认是当前redo损坏

对于这种情况,只能是屏蔽一致性,强制拉库,结果在拉库过程中报ORA-600 2662错误

这个错误相对比较简单,修改下相关scn即可,数据库open成功

asm disk被分区,格式化为ext4恢复

联系：手机/微信(+86 17813235971) QQ(107644445)

标题：asm disk被分区,格式化为ext4恢复

有客户因为没有认识到linux中的磁盘被asm使用,对其进行分区并且做成了ext4的文件系统，从history中获取客户操作命令

  600  fdisk -l
  601  fdisk /dev/sdb
  602  mkfs ext4 /dev/sdb1 
  603  fdisk -l
  604  mkfs -t ext4 /dev/sdb1 
  605  cd /
  606  mkdir u01
  607  mount /dev/sdb1 /u01
  608  df -h

确认磁盘情况,确认sdb直接被asm磁盘使用(asmdisk1)

[grid@racdb3 trace]$ ls -l /dev/asm*

磁盘前几个au被破坏严重.而且相关的备份block都已经损坏,基于这种情况,直接参考:
asm磁盘dd破坏恢复
 asm disk header 彻底损坏恢复
 asm disk 磁盘部分被清空恢复
通过底层恢复出来相关数据文件,并检测正常

进一步通过au分配列表获恢复redo,ctl等文件

H:\TEMP\asm-ext4\other>dir 
 驱动器 H 中的卷是 SSD-SX
 卷的序列号是 84EB-F434

 H:\TEMP\asm-ext4\other 的目录

导出数据库,遭遇个别表如下ORA-08103和ORA-01555两种错误，这种是由于个别block在做成文件系统的时候被损坏,底层恢复的时候block被置空导致,对其异常表进行单独处理即可

通过上述操作,实现客户数据的恢复,最大限度挽回客户损坏,再次提醒对于asm disk进行了误操作,建议第一时间保护现场(不要有任何的写入操作,可以最大限度恢复数据)
