Oracle Exadata坏盘导致磁盘组无法mount恢复

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

标题：Oracle Exadata坏盘导致磁盘组无法mount恢复

接到朋友求救有客户oracle exadata一体机的 asm磁盘组无法mount,希望我们提供恢复支持服务
经过分析和了解，大致问题是：磁盘空间已经超容量使用（部分数据不能完成ASM镜像），最近又损坏一块盘，导致asm 磁盘组无法mount。我们分析后，通过重构exadata celldisk数据，将asm 磁盘组 mount成功后，实现五套数据库全部open成功（由于底层磁盘部分数据损坏，导致部分数据访问报错，需要在oracle层面进行处理）。

本次问题的具体分析和处理如下：
存放数据库文件的磁盘组不能mount

根据客户的反馈该磁盘组几乎全部被使用,asmcmd lsdg看到Usable_file_MB已经出现负值.证明该磁盘组本身的normal没有完全存储两份数据,在这样的情况下,继续坏盘会导致部分数据只有一份,因此也就出现了这里的磁盘组无法正常mount成功.

linux 7安装11.2.0.4集群注意避开特定kernal版本

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

标题：linux 7安装11.2.0.4集群注意避开特定kernal版本

根据官方认证信息Orace RAC 11.2.0.4通过了Linux 7的认证

但是根据mos上描述对于linux 7的某些Kernel上可能会遭遇到OHASD启动失败,主要参考:ALERT: Grid Infrastructure Fails to Start OHASD With RedHat Linux or Oracle Linux with RedHat Compatible Kernel (RHCK) Version 3.10.0-514.21.2.EL7.X86_64 through 3.10.0-514.26.2.el7 (Doc ID 2282371.1)
具体报错类似:

---In Oracle restart:
# crsctl start has
CLSU-00100: operating system function: waitpid failed with error data: 0
CLSU-00101: operating system error message: Error 0
CLSU-00103: error location: usrgetgrp12
CLSU-00104: additional error information: child returned 232
CRS-4000: Command Start failed, or completed with errors.
CLSRSC-199: Timed out waiting for OHASD to start
---In Grid infrastructure:
#crsctl start crs
CLSB:1076092480: Oracle Clusterware infrastructure error in CRSCTL (OS PID 22363):
 GIPC API termination failed with error code 910

关于该问题的详细说明,请见:OHASD Fails to Start With Kernel Version 3.10.0-514.21.2.el7.x86_64 (Doc ID 2281492.1),建议在选择linux 7 安装11.2.0.4的集群最好避开Kernel:3.10.0-514.21.2.el7到3.10.0-514.26.2.el7之间版本

Oracle 11g丢失access$恢复方法
 11.1.0.7版本也会出现access$表丢失导致数据库无法启动
总结主要两类:1. 由于某种bug导致access$表丢失的故障,另外一种是由于坏块导致数据库核心基表损坏引起,对于这个库进行分析

dbv 检查坏块

通过Oracle Database Recovery Check脚本检查数据库结果

通过这里可以看出来,数据库需要的redo确实是721,但是recover无法应用成功,出现该问题的原因是由于控制文件信息不对导致

因为这个系统有一段历史,以前是客户的核心生产库,虚拟化资源给的比较多128G,后来核心生产迁移到其他系统,该系统跑一些边缘小业务,所以怀疑客户有可能下调了虚拟化的资源(cpu和内存),检查机器硬件资源

果然系统内存从128G下调到了32G,但是数据库sga估计没有对应降低

sga_target                           big integer 80G

基本上就是由于虚拟机内存下调,但是数据库sga配置过大导致该问题.

这个错误和以往版本中的kccpb_sanity_check_2比较类似,由于数据库异常关闭导致ctl写丢失导致
ORA-600 2131/kccpb_sanity_check_2解释

DESCRIPTION:
  This internal error is raised when the sequence number (seq#) of the
  current block of the controlfile is greater than the seq# in the controlfile header.
  The header value should always be equal to, or greater than the value
  held in the control file block(s).
  This extra check was introduced in Oracle 10gR2 to detect lost writes
  or stale reads to the header.
ARGUMENTS:
  Arg [a] seq# in control block header.
  Arg [b] seq# in the control file header.
  Arg 
FUNCTIONALITY:
  Kernel Cache layer Control file component.

文件系统损坏导致数据文件异常恢复

标题：文件系统损坏导致数据文件异常恢复

今天接到一个客户的服务请求,由于服务器被强制重启,数据库无法启动
ORA-1200报错

这是一个常见的ORA-1200错误,但是文件大小相差的有离谱实际大小729600个block,但是现在只有149760个block.不像是一般主机重启导致的数据库异常.通过再次咨询客户实际是什么情况,客户那边如实描述:三个磁盘的raid 5由于两个盘掉线,后来使用最后一个好的盘和最后掉线的盘,强制拉起raid,系统启动通过长时间的自检之后,就是出现这样的情况.通过进一步检查发现,发现大多数数据文件异常.
文件系统中数据文件截图

通过查询数据库确定文件大小情况

对比文件系统中的文件和数据库查询结果,可以发现绿色框中的文件全部大于文件系统中文件,蓝色框中的文件在文件系统中丢失.对于这样的情况,由于被强制online的磁盘中有坏道,导致文件系统损坏,从而出现大量文件大小异常甚至文件丢失;或者是由于选择错了上线的磁盘出现该问题(通过分析存在的文件,判断确定上线的盘没有问题),那就是文件系统故障导致.
底层重组恢复
解决该问题的方法是通过底层block恢复,重组oracle数据文件,并且检查恢复文件坏块情况.参考:Oracle 数据文件大小为0kb或者文件丢失恢复

分析文件坏块原因

由于文件所在block被覆盖或者磁盘坏道导致这部分block直接被空块填充.
这个客户比较幸运,直接open数据库成功,坏坏块进行分析判断业务表空间数据文件的坏块全部为index,业务数据0丢失.

ogg导致v$logfile查询频繁

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

标题：ogg导致v$logfile查询频繁

在某些版本的ogg中发现ogg抽取进程对v$logfile视图查询影响比较大

对应的sql语句为:SELECT 1 FROM V$LOGFILE WHERE(STATUS NOT IN (‘STALE’, ‘INVALID’) OR STATUS IS NULL) AND MEMBER <> :log_name AND EXISTS ( SELECT 1 FROM V$LOG WHERE GROUP# = V$LOGFILE.GROUP# AND THREAD# = :ora_thread AND SEQUENCE# = :ora_seq_no ) AND ROWNUM = 1
查询mos发现相关问题描述:Query On V$logfile Running Excessive Number Of Times After upgrading ogg to 11.2.1.0.32 or 12.1.2.1.5 or later (Doc ID 2116395.1)和Bug 22650790 : CE 12.1.2.1.9: Query on v$logfile running excessive number of times

根据mos描述在ogg对应版本中设置:TRANLOGOPTIONS _ENABLESTREAMLINEDDBLOGREADER

Oracle 11.2升级到18C

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

标题：Oracle 11.2升级到18C

Oracle 18c是12.2的后续版本,不管是从稳定性还是企业级用户的对数据库使用习惯(一般不使用初始版)都是一个可以考虑的选择.另外从11.2的标准服务期限将在2018年底到

还有一些客户可能需要使用到一些新功能必须imdb,far sync dg等,考虑把11.2的数据库升级到oracle 18c,结合oracle官方升级文档,这里提供一个手工升级11.2到18c的参考文档:Oracle 18C Non-CDB手工升级文档
主要参考官方文档:Oracle DB 18c – Complete Checklist for Manual Upgrades to Non-CDB Oracle Database 18c(Doc ID 2418045.1)
