4、管理Voting disk
<ol><li><span><span>[oracle@node-rac1 ~]$ crsctl query css votedisk </SPAN></SPAN></LI><li><span> 0. 0 /dev/raw/raw3 </SPAN></LI><li><span> 1. 0 /dev/raw/raw4 </SPAN></LI><li><span> 2. 0 /dev/raw/raw5 </SPAN></LI><li><span>Located 3 voting disk(s). </SPAN></LI></OL>
（2）备份Voting disk
（4）删除voting disk镜像盘
<ol><li><span><span>[root@node-rac1 ~]#/app/oracrs/product/11.0.6/crs/bin/crsctl \ </SPAN></SPAN></LI><li><span>></SPAN><span>delete css votedisk /dev/raw/raw5 </SPAN></LI><li><span>Successful deletion of voting disk /dev/raw/raw5. </SPAN></LI><li><span>[oracle@node-rac1 ~]$ crsctl query css votedisk </SPAN></LI><li><span> 0. 0 /dev/raw/raw3 </SPAN></LI><li><span> 1. 0 /dev/raw/raw4 </SPAN></LI></OL>
（5）添加voting disk镜像盘
<ol><li><span><span>[root@node-rac1 ~]#/app/oracrs/product/11.0.6/crs/bin/crsctl add css votedisk /dev/raw/raw5 Now formatting voting disk: /dev/raw/raw5. </SPAN></SPAN></LI><li><span>Successful addition of voting disk /dev/raw/raw5. </SPAN></LI><li><span>[oracle@node-rac1 ~]$ crsctl query css votedisk </SPAN></LI><li><span>crsctl query css votedisk </SPAN></LI><li><span> 0. 0 /dev/raw/raw3 </SPAN></LI><li><span> 1. 0 /dev/raw/raw4 </SPAN></LI><li><span> 2. 0 /dev/raw/raw5 </SPAN></LI></OL>
5、管理OCR
OCR磁盘主要用于记录节点成员的配置信息,如数据库、服务、实例、vip地址、监听器、应用进程等CRS资源配置信息，OCR可以存储在裸设备或者群集文件系统上。
<ol><li><span><span>[oracle@node-rac1 ~]$ ocrcheck </SPAN></SPAN></LI><li><span>Status of Oracle Cluster Registry is as follows : </SPAN></LI><li><span> Version: 2 </SPAN></LI><li><span> Total space (kbytes): 4000280 </SPAN></LI><li><span> Used space (kbytes): 3840 </SPAN></LI><li><span> Available space (kbytes) : 3996440 </SPAN></LI><li><span> ID: 1806962807 </SPAN></LI><li><span> Device/File Name: /dev/raw/raw1 </SPAN></LI><li><span> Device/File integrity check succeeded </SPAN></LI><li><span> Device/File Name: /dev/raw/raw2 </SPAN></LI><li><span> Device/File integrity check succeeded </SPAN></LI><li><span> Cluster registry integrity check succeeded </SPAN></LI></OL>
（2）OCR的备份与恢复
<ol><li><span><span>[oracle@node-rac1 ~]$ocrconfig -showbackup </SPAN></SPAN></LI><li><span>node-rac2 2011/03/11 13:10:27 /app/crs/product/11.0.6/crs/cdata/rac-cluster/backup00.ocr </SPAN></LI><li><span>node-rac2 2011/03/11 09:10:25 /app/crs/product/11.0.6/crs/cdata/rac-cluster/backup01.ocr </SPAN></LI><li><span>node-rac2 2011/03/11 05:10:24 /app/crs/product/11.0.6/crs/cdata/rac-cluster/backup02.ocr </SPAN></LI><li><span>node-rac2 2011/03/10 21:10:20 /app/crs/product/11.0.6/crs/cdata/rac-cluster/day.ocr </SPAN></LI><li><span>node-rac2 2011/03/10 21:10:20 /app/crs/product/11.0.6/crs/cdata/rac-cluster/week.ocr </SPAN></LI></OL>
恢复OCR的方法也很简单，例如：
（3）添加OCR镜像盘
<ol><li><span><span>[oracle@node-rac1 ~]$more /etc/oracle/ocr.loc </SPAN></SPAN></LI><li><span>ocrconfig_loc</SPAN><span>=/dev/raw/raw1 </SPAN></LI><li><span>ocrmirrorconfig_loc</SPAN><span>=/dev/raw/raw2 </SPAN></LI><li><span>ocrmirrorconfig_loc</SPAN><span>=/dev/raw/raw11 </SPAN></LI><li><span>local_only</SPAN><span>=</SPAN><span>FALSE</SPAN><span> </SPAN></LI></OL>
执行命令“ocrconfig -import”将OCR备份信息导入磁盘
6、快速卸载CRS
CRS安装非常简单，但是如果CRS出现问题，需要重新安装时，卸载CRS并不是一件轻松的事情，下面就重点讲述下如何在Linux下卸载CRS程序。本文来源gao.dai.ma.com搞@代*码#网 ，即：
<ol><li><span><span> [root@node-rac1 install]# /app/oracrs/product/11.0.6/crs/install/rootdeinstall.sh </SPAN></SPAN></LI><li><span>Verifying existence of ocr.loc file </SPAN></LI><li><span>Removing contents from OCR mirror device </SPAN></LI><li><span>2560+0 records in </SPAN></LI><li><span>2560+0 records out </SPAN></LI><li><span>10485760 bytes (10 MB) copied, 3.90308 seconds, 2.7 MB/s </SPAN></LI><li><span>Removing contents from OCR device </SPAN></LI><li><span>2560+0 records in </SPAN></LI><li><span>2560+0 records out </SPAN></LI><li><span>10485760 bytes (10 MB) copied, 3.84383 seconds, 2.7 MB/s </SPAN></LI></OL>
接着，在机(集)群中的任意一个节点上执行$ORA_CRS_HOME/install/rootdeinstall.sh。
（3）用图形界面OUI卸载crs
（4）删除剩余其它文件
<ol><li><span><span>rm -rf /app/oracrs/product/11.0.6/crs/ </SPAN></SPAN></LI><li><span>/bin/rm -rf /var/tmp/.oracle </SPAN></LI><li><span>/bin/rm -f /etc/oraInst.loc </SPAN></LI><li><span>rm -rf /etc/oracle/ </SPAN></LI><li><span>rm -f /etc/oratab </SPAN></LI></OL>
所有操作执行完毕后，重启集群的每个节点，重新安装CRS即可。
