Oracle 无备份情况恢复ocr和olr
Oracle 11.2 GI中OLR损坏的修复方法
Oracle RAC无备份情况恢复ocr和olr
原文地址：http://www.2cto.com/database/201404/290110.html
今天是2014-04-01，忙碌了一天终于有时间写点东西了。前段时间写了RAc中ocr存在备份的情况下如何恢复，今天写一下在没有备份情况下如何去重建ocr和olr呢？
最大的悲剧莫过于数据库坏了备份没了。让我想起了前几年流行的一句话：“最大的悲剧是人活着，钱没了”。总之备份重于一切。
情景介绍：
在11G中ocr的asm磁盘组被用户不小心删了且所有备份都误删，olr呢也损坏了。至此悲剧重演。
恢复过程：（其实就是使用root.sh重建ocr的过程，重建之后可能需要重新注册相关资源如listener or database 实例等！）
1、清空所有节点cluster配置信息：（11G中存在rootcrs.sh脚本，该脚本默认存在于$GRID_HOME/crs/install）。
注，该脚本需要在root下执行，否则会有错误提示
[grid@rac-one install]$ ./rootcrs.pl
You must be logged in as root to run this script.
Log in as root and rerun this script.
2014-04-01 17:08:12: Not running as authorized user
Insufficient privileges to execute this script.
root or administrative privileges needed to run the script.
了解该脚本的功能可以查看-help。如升级、回退、重新配置等待》
[root@rac-two install]# ./rootcrs.pl -help
Usage:
rootcrs.pl [-verbose] [-upgrade [-force] | -patch]
[-paramfile ]
[-deconfig [-deinstall] [-keepdg] [-force] [-lastnode]]
[-downgrade -oldcrshome -version [-force] [-lastnode]]
[-unlock [-crshome ] [-nocrsstop]]
[-init]
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 script is executing on to be considered
as the last node of deconfiguration or downgrade, and perform
actions associated with deconfiguring or downgrading 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 or dwongrade 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
-init Reset the permissions of all files and directories under CRS home
If neither -upgrade nor -patch is supplied, a new install is performed

二、重建ocr和olr,使用root.sh脚本完成重建，其实这就是在安装RAC中执行的脚本，默认位置为：$GRID_HOME/;
eg：

另外注意，如果asm磁盘损坏了那么需要重新修复磁盘，然后会自动重新创建之前的diskgroup.

3、检查资源信息：
现在呢开始使用srvctl和crsctl工具，这是oracle RAC 经常使用的，另外还有一个工具是oifcfg配置网卡信息等。不在 介绍了。
[root@rac-one bin]# ./crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online

4、添加资源
可以看到目前启动的缺少本地监听和database资源和实例，那么下面开始重新注册这些信息到ocr中，
注册listener：
注：使用grid用户：
[grid@rac-one ~]$ srvctl add listener -l listener
PRCN-2061 : Failed to add listener ora.LISTENER.lsnr
PRCN-2065 : Port(s) 1521 are not available on the nodes given

提示1521该端口被ora.rac-two.vip所使用，暂且跳过。

至此监听添加到ocr完毕。下面开始添加db，注意使用oracle用户：
继续添加：
[grid@rac-one ~]$ su - oracle
Password:
[oracle@rac-one ~]$ srvctl add database -h
Adds a database configuration to the Oracle Clusterware.

我们在启动clusterware 发现无法启动了
[root@rac1 bin]# ./crsctl start has
CRS-4123: Oracle High Availability Services has been started.
[root@rac1 bin]# ./crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4530: Communications failure contacting Cluster Synchronization Services daemon
CRS-4534: Cannot communicate with Event Manager
ocr和vote disk损坏恢复步骤大致如下：
1）停止所有节点clusterware # crsctl stop crs # crsctl stop crs -f 2）以root用户在其中一个节点独占模式启动clusterware # crsctl start crs -excl -nocrs 备注：如果发现crsd在运行，那么通过如下命令将之停止。 # crsctl stop resource ora.crsd -init 3）创建新的存放ocr和vote disk的磁盘组，磁盘组名和原有的一致(如果想改变位置，需修改/etc/oracle/ocr.loc文件) 备注：如发现无法创建等情况，可以采用如下删除磁盘组等排错思路 SQL> drop diskgroup disk_group_name force including contents; 4）还原ocr，并检查 # ocrconfig -restore file_name # ocrcheck 5）恢复表决磁盘，并检查 # crsctl replace votedisk +asm_disk_group # crsctl query css votedisk 6）停止独占模式运行的clusterware # crsctl stop crs -f 7）所有节点正常启动clusterware # crsctl start crs 8）CVU验证所有RAC节点OCR的完整性 $ cluvfy comp ocr -n all -verbose
