在linux AS5.4 64bit 安装CRS时，执行root.sh时报错
[root@rac02 crs]# sh root.sh
WARNING: directory '/opt/ora10g/product/10.2.0' is not owned by root
WARNING: directory '/opt/ora10g/product' is not owned by root
WARNING: directory '/opt/ora10g' is not owned by root
WARNING: directory '/opt' is not owned by root
Checking to see if Oracle CRS stack is already configured
/etc/oracle does not exist. Creating it now.
Setting the permissions on OCR backup directory

/opt/ora10g/product/10.2.0/crs/install/rootconfig: line 815: 10438 segment fault
$CH/bin/ocrconfig -upgrade $CRS_ORACLE_OWNER $CRS_DBA_GROUP
Failed to upgrade Oracle Cluster Registry configuration
首先开始检查连个节点的/etc/hosts的IP与主机名对应是否都正确，检查/etc/sysconfig/network ，裸设备的权限，检查无误后没找到其他原因
重新安装依旧失败。。。。
按照metalink做法
Failed to upgrade Oracle Cluster Registry segmentation fault executing ocrconfig [ID 393553.1]
适用于:
Linux x86-64 Oracle Enterprise Version: 10.1.0.2 to 11.1.0.7 - Release: 10.1 to 11.1
Symptoms
Segmentation fault when root.sh execute ocrconfig

导致root.sh执行失败的原因是：
The symbolic link to gcc32 and g++32 were broken .
Action:
#which gcc
/usr/bin/gcc
#which g++
/usr/bin/g++
#ls -ltra /usr/bin/gcc*
-rwxr-xr-x 2 root root 94360 Dec 1 2004 /usr/bin/gcc32
-rwxr-xr-x 1 root root 914 Feb 23 2005 /usr/bin/gcc
#ls -ltra /usr/bin/g+*
-rwxr-xr-x 3 root root 95576 Dec 1 2004 /usr/bin/g++32
-rwxr-xr-x 1 root root 914 Feb 23 2005 /usr/bin/g++
Solution
1. #cd /usr/bin
2. #mv gcc gcc.script
3. #mv g++ g++.script
4. #ln -s gcc32 gcc
5. #ln -s g++32 g++
以root身份执行以下 1-4
1.Make sure the symbolic link is right You need to see something like
#ls -lrt /usr/bin/gcc
lrwxrwxrwx 1 root root 5 Feb 16 2006 /usr/bin/gcc -> gcc32
2.ls -lrt /usr/bin/g++
lrwxrwxrwx 1 root root 5 Feb 16 2006 /usr/bin/g++ -> g++32
3. Remove the CRS Note 239998.1 How to Clean Up After a Failed Oracle Clusterware (CRS)
4. Reinstall CRS
metalink上的报错是line 815:
20749 Segmentation fault $CH/bin/ocrconfig -upgrade $CRS_ORACLE_OWNER，
但我的报错却是
line 815: 10438 segment fault
$CH/bin/ocrconfig -upgrade $CRS_ORACLE_OWNER $CRS_DBA_GROUP，错误类似，还是抱着试试的态度试了下
我的linux是AS5.4 64位的,起初按照metalink的做法并未成功，折腾了好久
最后查看/usr/bin目录下并没有gcc32
只有gcc34,后又按照metalink的 Solution 将gcc32的部分替换成gcc34,以下是执行步骤
Solution
1.root@rac01]# cd /usr/bin
2.[root@rac01 bin]# mv gcc gcc.script
3.[root@rac01 bin]# mv g++ g++.script
4.[root@rac01 bin]# ln -s gcc34 gcc
5.[root@rac01 bin]# ln -s g++34 g++
7.[root@rac01 bin]# ls -lrt /usr/bin/gcc
lrwxrwxrwx 1 root root 5 04-21 19:06 /usr/bin/gcc -> gcc34
8.[root@rac01 bin]# ls -lrt /usr/bin/g++
lrwxrwxrwx 1 root root 5 04-21 19:06 /usr/bin/g++ -> g++34
9.删除Linux两个节点的CRS
10. 分别在两个节点运行$ORA_CRS_HOME/install目录的rootdelete.sh，rootdeinstall.sh 脚本
Rootdelete.sh 接受如 nosharedvar/sharedvar, and nosharedhome/sharedhome的选项
11. Stop the Nodeapps on all nodes:
root@rac01 bin]# srvctl stop nodeapps -n
12.删除两个节点的以下目录
root@rac01]# rm /etc/oracle/*
root@rac01]# rm -f /etc/init.d/init.cssd
root@rac01]# rm -f /etc/init.d/init.crs
root@rac01]# rm -f /etc/init.d/init.crsd
root@rac01]# rm -f /etc/init.d/init.evmd
root@rac01]# rm -f /etc/rc2.d/K96init.crs
root@rac01]# rm -f /etc/rc2.d/S96init.crs
root@rac01]# rm -f /etc/rc3.d/K96init.crs
root@rac01]# rm -f /etc/rc3.d/S96init.crs
root@rac01]# rm -f /etc/rc5.d/K96init.crs
root@rac01]# rm -f /etc/rc5.d/S96init.crs
root@rac01]# rm -Rf /etc/oracle/scls_scr
root@rac01]# rm -f /etc/inittab.crs
root@rac01]# cp /etc/inittab.orig /etc/inittab
13. 如果有以下进程, kill掉 EVM, CRS, and CSS 进程
所有节点上执行
#ps -ef | grep crs
kill PID
#ps -ef | grep evm
kill PID
#ps -ef | grep css
kill PID
14. 在两个节点删除.oracle
#rm -f /var/tmp/.oracle/*
#rm -f /tmp/.oracle/*
15. Remove the ocr.loc
Usually the ocr.loc can be found at /etc/oracle
16. De-install the CRS home in the Oracle Universal Installer
17.删除CRS的安装目录
我的目录是 /opt/ora10g/product/10.2.0/crs/install
在两个节点分别执行
#rm -rf /ora10g/*
18. 清空OCR,VotingDisk裸设备
root@rac01]# dd if=/dev/zero of=/dev/raw/raw1 bs=8192 count=4000
root@rac01]# dd if=/dev/zero of=/dev/raw/raw2 bs=8192 count=4000
确保raw权限正确
[root@rac01 ~]# ls -al /dev/raw/
总计 0
drwxr-xr-x 2 oracle oinstall 120 04-21 19:14 .
drwxr-xr-x 14 root root 4660 04-21 20:50 ..
crw-r--r-- 1 oracle oinstall 162, 1 04-22 11:33 raw1

crw-r----- 1 oracle oinstall 162, 4 04-22 11:33 raw4
18.重新安装CRS 问题解决
