本文简介

写这篇blog的情况是这样的,rac启动有问题,但是$GRID_HOME/log下的文件太多了,我就把下边的内容清空了,结果是集群更加不能启动就连基本的日志也没有了,重启OS无效,最后在仔细的想了想查看了一下运行正常的库的$GRID_HOME/log下的文件结构,发现有的文件夹最后有个T或t的权限,由此联想到可能是权限的缘故导致的,于是上MOS搜了搜文章果然搜到几篇文章,11.2.0.3.6以上比较好解决,但是小于这个版本的就不好弄了,自己总结的方法是重新跑root.sh脚本,而跑完后集群中注册的很多资源不存在了,于是这个又涉及到OCR的备份与恢复。另外执行root.sh若是顺序不对,或者其他的原因可能导致asm实例号和主机号不一致,就是rac1上的实例名是+ASM2,这个虽然没有啥影响,但是看着着实不爽,因此更改它们直接的对应关系也比较重要,所以总体而言就引出了文章开头提出的6个问题。

相关知识点扫盲

Clusterware 在运行期间需要两个文件: OCR 和 Voting Disk. 这 2 个文件必须存放在共享存储上。 OCR 用于解决健忘问题, Voting Disk 用于解决脑裂问题。

OCR Disk

Oracle Clusterware把整个集群的配置信息放在共享存储上,这个存储就是OCR Disk. 在整个集群中,只有一个节点能对OCR Disk 进行读写操作,这个节点叫作Master Node,所有节点都会在内存中保留一份OCR的拷贝,同时有一个OCR Process 从这个内存中读取内容。 OCR 内容发生改变时,由Master Node的OCR Process负责同步到其他节点的OCR Process。

健忘问题是由于每个节点都有配置信息的拷贝,修改节点的配置信息不同步引起的。Oracle 采用的解决方法就是把这个配置文件放在共享的存储上, 这个文件就是 OCR Disk。OCR 中保存整个集群的配置信息,配置信息以"Key-Value" 的形式保存其中。 在 Oracle10g 以前, 这个文件叫作 Server Manageability Repository(SRVM). 在 Oracle 10g, 这部分内容被重新设计,并重名为 OCR.。在 Oracle Clusterware 安装的过程中, 安装程序会提示用户指定 OCR 位置。并且用户指定的这个位置会被记录在/etc/oracle/ocr.loc(Linux System、AIX) 或者/var/opt/oracle/ocr.loc(Solaris System)文件中。 而在 Oracle 9i RAC 中,对等的是 srvConfig.Loc文件。 Oracle Clusterware在启动时会根据这里面的内容从指定位置读入 OCR 内容。

OCR key

整个 OCR 的信息是树形结构,有 3 个大分支。分别是 SYSTEM,DATABASE 和 CRS。每个分支下面又有许多小分支。这些记录的信息只能由 root 用户修改。

OCR包含的内容

OCR中通常包含下列内容:

  • 节点成员信息
  • 数据库实例,节点,以及其他的映射关系
  • ASM
  • 资源配置信息(vip,services等等)
  • 服务特性(Service characteristics)
  • Oracle集群中相关进程的信息
  • CRS控制的第三方应用程序信息

OCR存储内容的表现形式

  1. 同样地与Windows注册表来类比,OCR其存储内容的表现形式与其相同,是采用键值对的方式来展现。
  2. 整个OCR 的信息是树形结构,有3个大分支。分别是SYSTEM,DATABASE 和CRS。
  3. 每个分支下面又有许多小分支。这些记录的信息只能由root用户修改。
  4. 可以使用ocrdump命令将其内容全部导出或者按分支进行导出。

Voting Disk

Voting Disk 这个文件主要用于记录节点成员状态,在出现脑裂时,决定那个 Partion 获得控制权,其他的 Partion 必须从集群中剔除。在安装 Clusterware 时也会提示指定这个位置。安装完成后可以通过如下命令来查看 Voting Disk 位置。

健忘症(Amnesia)

集群环境配置文件不是集中存放的,而是每个节点都有一个本地副本,在集群正常运行时,用户可以在任何节点更改集群的配置,并且这种更改会自动同步到其他节点。有一种特殊情况: 节点 A 正常关闭, 在节点 B 上修改配置, 关闭结点 A,启动结点B。 这种情况下,修改的配置文件是丢失的, 就是所谓的健忘症。OCR 用于解决健忘问题。

健忘是由于某个节点更新了OCR中的内容,而集群中的另外一些节点此时处于关闭,维护或重启阶段,OCR Master进程来不及将其信息更新到这些异常节点缓存而导致的不一致。譬如,在A节点发出了添加ocr镜像的命令,在这个时候B节点处于重启阶段。重启后A已经更新完毕,而此时B并不知道已经为ocr增加了一个新的镜像磁盘,健忘由此而生。

如下例,节点bo2dbp添加了新的ocr之后,配置文件发生了变化,此时节点bo2dbs的ocr.loc会被更新,如果bo2dbs处于关闭或重启阶段,则该文件得不到该更新,此即位健忘一例。

脑裂(Split Brain)

在集群中,节点间通过某种机制(心跳)了解彼此的健康状态,以确保各节点协调工作。假设只有"心跳"出现问题, 各个节点还在正常运行, 这时,每个节点都认为其他的节点宕机了, 自己是整个集群环境中的"唯一建在者",自己应该获得整个集群的"控制权"。 在集群环境中,存储设备都是共享的, 这就意味着数据灾难, 这种情况就是"脑裂"解决这个问题的通常办法是使用投票算法(Quorum Algorithm). 它的算法机理如下:集群中各个节点需要心跳机制来通报彼此的"健康状态",假设每收到一个节点的"通报"代表一票。对于三个节点的集群,正常运行时,每个节点都会有 3 票。 当结点 A 心跳出现故障但节点 A 还在运行,这时整个集群就会分裂成 2 个小的 partition。 节点 A 是一个,剩下的 2 个是一个。 这是必须剔除一个 partition 才能保障集群的健康运行。对于有 3 个节点的集群, A 心跳出现问题后, B 和 C 是一个 partion,有 2 票, A只有 1 票。 按照投票算法, B 和 C 组成的集群获得控制权, A 被剔除。如果只有 2 个节点,投票算法就失效了。 因为每个节点上都只有 1 票。 这时就需要引入第三个设备: Quorum Device. Quorum Device 通常采用饿是共享磁盘,这个磁盘也叫作Quorum disk。 这个 Quorum Disk 也代表一票。 当 2 个结点的心跳出现问题时, 2 个节点同时去争取 Quorum Disk 这一票, 最早到达的请求被最先满足。 故最先获得 Quorum Disk的节点就获得 2 票。另一个节点就会被剔除。

OCR命令系列

ocrdump

该命令能以ASCII的方式打印出OCR的内容,但是这个命令不能用作OCR的备份恢复,也就是说产生的文件只能用作阅读,而不能用于恢复。

命令格式: ocrdump [-stdout] [filename] [-keyname name] [-xml]

参数说明:

-stdout: 把内容打印输出到屏幕上

Filename:内容输出到文件中

-keyname:只打印某个键及其子健内容

-xml:以xml格式打印输出

示例:把system.css键的内容以.xml格式打印输出到屏幕

[root@raw1 bin]# ./ocrdump -stdout -keyname system.css -xml|more

\

\03/08/2010 04:28:41\

\/dev/raw/raw1\

\./ocrdump.bin -stdout -keyname system.css -xml \

......

这个命令在执行过程中,会在$CRS_HOME/log/\/client 目录下产生日志文件,文件名ocrdump_\.log,如果命令执行出现问题,可以从这个日志查看问题原因。

ocrcheck

Ocrcheck 命令用于检查OCR内容的一致性,命令执行过程会在$CRS_HOME/log/nodename/client 目录下产生ocrcheck_pid.log 日志文件。 这个命令不需要参数。

ocrconfig

该命令用于维护OCR 磁盘,安装clusterware过程中,如果选择External Redundancy冗余方式,则只能输入一个OCR磁盘位置。 但是Oracle允许配置两个OCR 磁盘互为镜像,以防止OCR 磁盘的单点故障。 OCR 磁盘和Votedisk磁盘不一样,OCR磁盘最多只能有两个,一个Primary OCR 和一个Mirror OCR。

Oracle RAC OCR 的备份与恢复

Oracle Clusterware把整个集群的配置信息放在共享存储上,这些信息包括了集群节点的列表、集群数据库实例到节点的映射以及CRS应用程序资源信息。也即是存放在ocr 磁盘(或者ocfs文件)上。因此对于这个配置文件的重要性是不言而喻的。任意使得ocr配置发生变化的操作在操作之间或之后都建议立即备份ocr。

因为OCR的内容如此重要,Oracle 每4个小时对其做一次备份,并且保留最后的3个备份,以及前一天,前一周的最后一个备份。 这个备份由Master Node CRSD进程完成,备份的默认位置是$CRS_HOME/crs/cdata/\目录下。 每次备份后,备份文件名自动更改,以反应备份时间顺序,最近一次的备份叫作backup00.ocr。这些备份文件除了保存在本地,DBA还应该在其他存储设备上保留一份,以防止意外的存储故障。

与Oracle数据库备份恢复相似,OCR的备份也有物理备份或逻辑备份的概念,因此有两种备份方式,两种恢复方式。

常用命令:

crsctl query css votedisk

lquerypv -h /dev/rhdisk2

crsctl stop has -f

crsctl start has

crsctl stat res -t

dd备份恢复

备份表决磁盘:

dd if=/dev/raw/raw3 of=/tmp/votedisk_lhr.bak bs=1024k count=4

恢复表决磁盘:

dd if=/tmp/votedisk_lhr.bak of=/dev/raw/raw3 bs=1024k count=4

注:11g不推荐使用dd来进行备份恢复,盘头一般是前4K

kfed恢复磁盘头

dd if=/dev/rhdisk2 of=/asm_rhdisk2_dd.bak bs=1024 count=4

dd if=/dev/zero of=/dev/rhdisk2 bs=1024 count=4

kfed repair /dev/rhdisk2

http://blog.itpub.net/26736162/viewspace-1694199/

md_backup和md_restore恢复磁盘头

asmcmd md_backup /oracle/app/11.2.0/grid/cdata/ZFTPCCDB-crs/asm_md_backup.bak

asmcmd md_restore /oracle/app/11.2.0/grid/cdata/ZFTPCCDB-crs/asm_md_backup.bak

dd if=/dev/rhdisk2 of=/asm_rhdisk2_dd.bak bs=1024k count=4

dd if=/dev/zero of=/dev/rhdisk2 bs=1024k count=4

crsctl stop has -f

crsctl start has

ASMCMD [+] > startup force nomount;

ASMCMD [+] > md_restore /asm_rhdisk2_dd.bak

ASMCMD [+] > md_backup /rman/asm_md.bak

dd if=/dev/zero of=/dev/rhdisk2 bs=1024 count=4

crsctl stop has -f

crsctl start has

ASMCMD [+] > startup force nomount;

ASMCMD [+] > md_restore /rman/asm_md.bak

关于md_backup和md_restore更多内容可以参考:http://blog.itpub.net/26736162/viewspace-2121309/

物理备份与恢复(自动备份)

缺省情况下,Oracle 每4个小时对其做一次备份,并且保留最后的3个副本,以及前一天,前一周的最后一个备份副本。用户不能自定义备份频率以及备份文件的副本数。

对于OCR的备份由是由Master Node CRSD进程完成,因此备份的默认位置是$CRS_HOME/crs/cdata/\目录下。

备份的文件会自动更名,以反应备份时间顺序,最近一次的备份叫作backup00.ocr。

由于是在Master Node的节点之上进行备份,因此备份文件仅存在于Master Node节点。

对于Master Node的节点crash之后则由剩余节点接管。

备份目录可以通过ocrconfig -backuploc \ 命令修改。

OCR磁盘最多只能有两个,一个Primary OCR 和一个Mirror OCR。两者互为镜像以避免单点故障。

对于物理备份恢复,不能简单的使用操作系统级别的复制命令(使用ocr文件时)来完成,该操作将导致ocr不可用。

对于物理备份,仅仅只能使用restore方式来进行恢复,而不支持import方式

注:

ocssd:用于管理与协调集群中各个节点的关系,并用于节点通信。该进程非常的重要,如果这个进程异常中止,会导致系统自动重启。在某些极端的情况下,如果ocssd无法正常启动,就会导致操作系统循环重启。

crsd:监控节点各个资源,当某个资源发生异常是,自动重启或者切换该资源。

evmd:是一个基于后台的事件检测程序。

oclskd:该守护进程是Oracle 11g(11.10.6)新增的一个后台进程,主要是用于监控RAC数据库节点实例,当某个实例挂起时,就重启该节点。

逻辑备份与恢复(手动备份)

其实OCR也可以通过手动的方式导出、导入、方法如下:

ocrconfig -export /tmp/ocr_bak

ocrconfig -import /tmp/ocr_bak

使用ocrconfig -export 方式产生的备份,统称之为逻辑备份。

对于重大的ocr配置发生变化前后,如添加删除节点,修改集群资源,创建数据库等,都建议使用逻辑备份。

对于由于错误配置而导致的ocr被损坏的情形下,我们可以使用ocrconfig -import方式进行恢复。

对于这种逻辑方式也可以还原丢失或损坏的ocr磁盘(文件)。

如何修复11.2 Grid权限误操作

关于Oracle GRID HOME文件目录的权限问题

  1. chown -R 误操作了,将整个/u01/app的权限修过了如何恢复?
  2. 删除了$GRID_HOME/log文件夹下的所有内容,集群不能启动,如何恢复?

使用chown -R 误操作了,将整个/u01/app的权限修过了,导致grid无法启动。,搜了下mos发现了一篇文档:Tips for checking file permissions on GRID environment(ID 1931142.1)

该文档中描述到,$GRID_HOME/crs/utl下面的几个文件中记录了整个GRID_HOME下面的文件和目录的相关权限。

Check the permissions from the following 2 files which are created during Grid Infrastructure installation.

In $GRID_HOME/crs/utl (for 11.2 and 12.1.0.1) and \/crs/utl/\ (for 12.1.0.2) directory:

crsconfig_dirs :which has all directories listed in \ and their permissions

crsconfig_fileperms :which has list of files and their permissions and locations in \.

我们来看下是否是这样的,cd $ORACLE_HOME/crs/utl:

我们可以看到,确实是这样,crsconfig_dirs里面记录所有$GRID_HOME相关目录的权限。crsconfig_fileperms中记录了文件的权限.

校验权限

我们可以通过命令来校验:Validate the \ by using cluvfy tool.

$ cluvfy comp software -n all -verbose

解决

所以要解决这个问题其实并不难,我们大致可以通过如下几种方法来解决:

1. 根据前面的几个权限配置脚本自己参考进行修改,实际上并不难,直接UE编辑就很快搞定.

2. 根据Mos文档提供的建议通过 $GRID_HOME/crs/install/rootcrs.pl -init 或 roothas.pl -init进行解决. rootcrs.pl –init是在PSU>11.2.0.3.6下执行的,如果PSU\<11.2.0.3.6可以执行如下两条命令来实现同样的效果

\/crs/install/rootcrs.pl -unlock

\/crs/install/rootcrs.pl -patch

3.采用MOS1515018.1文档提供的脚本在正常库上生成脚本,然后将生成的脚本在异常库上执行从而来修复权限问题(应该和方法2结合使用)。

4. 11gR2可以deconfig crs的配置,然后重新跑root.sh即可。重新跑root.sh脚本并不影响数据库,所以无需担心(个人推荐的一种方式).

$ORACLE_HOME/crs/install/rootcrs.pl -deconfig -force -verbose

$ORACLE_HOME/root.sh

5. 如果是rac的某个节点的误操作,那么还可以通过delete node然后add node来做,不过这个相对麻烦太多了,但是或许是最保险的一种方式。oracle也推荐这样,因为你如果人为修改文件权限,很难保证以后运行过程中不会出现什么问题。

补充:

Linux环境中还可以通过getfacl和setfacl来进行操作,如下是例子:

1) getfacl /home/grid/app/11.2/grid > dir_privs.txt

2) set –restore dir_privs.txt

总结:

在安装有GI的环境下,权限、属主是严格被设定的,任何对于它们的错误修改容易引发一系列的问题,而且这些问题往往都很诡异很难按照常规的思路去诊断。万一权限或属主被修改了可以通过rootcrs.pl -init及permission.pl进行修复,rootcrs.pl –init仅修复GI的核心目录,所以其修复速度较快,如果遇到GI无法启动的问题,建议首选这种方法以使GI能够快速启动,但其缺点在于无法全量的进行修复,GI虽然正常了,并不能保证之后的运行过程中不出现这样那样的问题,这时就需要permission.pl出场了,permission.pl的运行模式决定了源库(权限正确的库)与目标库(权限错误的库)间的软件版本尽可能的一致,所以源库一定要选好,否则问题会更糟,另外如果源、目标两个库的安装目录不一样还需要对permission*脚本作调整后再执行。

所以个人建议还是跑root.sh来的稳妥一点。

MOS 1515018.1 permission.pl脚本的使用

chmod 755 permission.pl

oracle用户获取ORACLE_HOME: ./permission.pl $ORACLE_HOME

root用户获取GRID_HOME: ./permission.pl $ORACLE_HOME

Script generates two files
a. permission-\ - This contains file permission in octal value, owner and group information of the files captured
b. restore-perm-\ - This contains command to change the permission, owner, and group of the captured files

拷贝到目标主机后分别执行:

chmod 755 restore-perm-\.cmd

./restore-perm-\.cmd

如何修复ASM实例名和节点名不一致的情况

对于10g的情况,我们可以参考Dave大神的blog:RAC修改ASM实例名的步骤:http://blog.csdn.net/tianlesoftware/article/details/6275827

对于11g的情况,我们只能重新执行root.sh脚本来修复这个问题。

如何彻底清除CRS信息

ZFTPCCDB1:root:/>$ORACLE_HOME/crs/install/rootcrs.pl -h

Unknown option: h

Usage:

rootcrs.pl [-verbose] [-upgrade [-force] | -patch]

[-paramfile \]

[-deconfig [-deinstall] [-keepdg] | -downgrade] [-force] [-lastnode]

[-downgrade] [-oldcrshome \] [-version \]

[-unlock [-crshome \] [-nocrsstop]]

Options:

-verbose Run this script in verbose mode

-upgrade Oracle HA is being upgraded from previous version

-patch Oracle HA is being upgraded to a patch version

-paramfile Complete path of file specifying HA parameter values

-lastnode Force the node this is executing on to be considered the

last node of the install and perform actions associated

with configuring the last node

-downgrade Downgrade the clusterware

-version For use with downgrade; special handling is required if

downgrading to 9i. This is the old crs version in the format

A.B.C.D.E (e.g 11.1.0.6.0).

-deconfig Remove Oracle Clusterware to allow it to be uninstalled or reinstalled.

-force Force the execution of steps in delete that cannot be verified

to be safe

-deinstall Reset the permissions on CRS home during de-configuration

-keepdg Keep existing diskgroups during de-configuration

-unlock Unlock CRS home

-crshome Complete path of crs home. Use with unlock option.

-oldcrshome For use with downgrade. Complete path of the old crs home.

-nocrsstop used with unlock option to reset permissions on an inactive grid home

If neither -upgrade nor -patch is supplied, a new install is performed

To see the full manpage for this program, execute:

perldoc rootcrs.pl

根据MOS How to Proceed from Failed 11gR2 Grid Infrastructure (CRS) Installation (文档 ID 942166.1) 文档,若要重新执行root.sh脚本,我们可以如下操作:

在除最后一个节点外的所有节点执行:$ORACLE_HOME/crs/install/rootcrs.pl -deconfig -force -verbose

在最后一个节点执行:$ORACLE_HOME/crs/install/rootcrs.pl -deconfig -force -verbose -lastnode

重启OS后再执行:$ORACLE_HOME/root.sh

需要注意的一点是,我们在执行完$ORACLE_HOME/crs/install/rootcrs.pl -deconfig -force -verbose执成之后需要删除如下的文件:
