如何重装10g clusterware集群软件?
一般情况下我会说把DB、CRS停掉,手动删除ORA_CRS_HOME及/etc(或者/opt)目录下的ora*配置文件，使用dd命令清理LUN的头部。再重装一般就没有问题了，但实践过程中往往会因为清理地不够彻底而出现问题。
今天同事问我有没有彻底卸载CRS的文档，到metalink上搜了一圈结果还真没有，最后从Alejandro Vargas’ Blog上找到一份比较权威的文档，这里分享一下。

10g and 11.1 RAC: How to Clean Up After a Failed CRS Install
————————————————————
Not cleaning up a failed CRS install can cause problems like node reboots.
Follow these steps to clean up a failed CRS install:
1. Run the rootdelete.sh script then the rootdeinstall.sh script from the
$ORA_CRS_HOME/install directory on any nodes you are removing CRS from. Running
these scripts should be sufficent to clean up your CRS install. Rootdelete.sh
accepts options like nosharedvar/sharedvar, and nosharedhome/sharedhome. Make
yourself familiar with these options by reading the Oracle Clusterware and
Oracle Real Application Clusters Administration and Deployment Guide.
If you have any problems with these scripts please open a service request.
If for some reason you have to manually remove the install due to problems
with the scripts, continue to step 2:
2. Stop the Nodeapps on all nodes:
srvctl stop nodeapps -n
3. Prevent CRS from starting when the node boots. To do this issue the following
as root:
Sun:
rm /etc/init.d/init.cssd
rm /etc/init.d/init.crs
rm /etc/init.d/init.crsd
rm /etc/init.d/init.evmd
rm /etc/rc3.d/K96init.crs
rm /etc/rc3.d/S96init.crs
rm -Rf /var/opt/oracle/scls_scr
rm -Rf /var/opt/oracle/oprocd
rm /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab
Linux:
rm /etc/oracle/*
rm -f /etc/init.d/init.cssd
rm -f /etc/init.d/init.crs
rm -f /etc/init.d/init.crsd
rm -f /etc/init.d/init.evmd

rm -f /etc/rc5.d/S96init.crs
rm -Rf /etc/oracle/scls_scr
rm -f /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab

rm /etc/rc.d/rc2.d/S96init.crs
rm -Rf /etc/oracle/scls_scr
rm -Rf /etc/oracle/oprocd
rm /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab
4. If they are not already down, kill off EVM, CRS, and CSS processes or reboot
the node:
ps -ef | grep crs
kill
ps -ef | grep evm
kill
ps -ef | grep css
kill
Do not kill any OS processes, for example icssvr_daemon process !
5. If there is no other Oracle software running (like listeners, DB’s, etc…),
you can remove the files in /var/tmp/.oracle or /tmp/.oracle. Example:
rm -f /var/tmp/.oracle/*
or
rm -f /tmp/.oracle/*
6. Remove the ocr.loc
Usually the ocr.loc can be found at /etc/oracle
7. De-install the CRS home in the Oracle Universal Installer
8. Remove the CRS install location.
9. Clean out the OCR and Voting Files with dd commands. Example:
dd if=/dev/zero of=/dev/rdsk/V1064_vote_01_20m.dbf bs=1M count=256
dd if=/dev/zero of=/dev/rdsk/ocrV1064_100m.ora bs=1M count=256
See the Clusterware Installation Guide for sizing requirements…
If you placed the OCR and voting disk on a shared filesystem, remove them.
If you are removing the RDBMS installation, also clean out any ASM disks if
they have already been used.
10. The /tmp/CVU* dir should be cleaned also to avoid the cluvfy misreporting.
11. It is good practice to reboot the node before starting the next install.
12.If you would like to re-install CRS, follow the steps in the RAC Installation manual.
