Oracle 10g Rac root.sh Failure at final check of Oracle CRS stack 10 解决方法

一.问题说明

安装环境：Oracle linux 6.1

数据库： 10.2.0.1

安装Oracle 10g的RAC,在第一个节点执行root.sh 时报错，如下：

[root@rac1 ~]# /u01/app/10.2.0/grid/root.sh

WARNING: directory '/u01/app/10.2.0' is notowned by root

Failure at final check of Oracle CRS stack.

二．MOS上有篇文档说明这个问题：

2.1 文档一：

Root.sh failed at Failure at final check ofOracle CRS stack 10 [ID 725878.1]

Case

This particular case is caused by the OSinit system does not working.

" Failure at final check of Oracle CRS stack.
10"
means CRS daemon did not startup during 600 seconds period.

In the root.sh script, it adds CRS relatedentry in /etc/inittab, run "init q" and expect 3 CRS related daemonprocesses to start, eg:

init.cssd
init.crsd
init.evmd

With init system problem, none of thesedaemon processes are spawned, this causes CRS process startup failure as theyrely on the CRS daemon processes to start first.
--这里说明是init system problem 出现问题，导致进程无法启动。可以通过以下方法验证这个问题：

This can be verified by adding a simple entry in /etc/inittab:

test:2:once:/usr/bin/echo "HELLOTEST" > /tmp/test.log

run "init q" as root user. If the init is working, then there shouldbe a file /tmp/test.log generated.

Solution

--MOS上仅给出了AIX上的解决方案，如下：

Please consult with system administrator tofix initissue.

Here the solution is only valid for AIXplatform:

1. Starting the script install_assist (AIXGUI utility Installation Assistance)
2. Updating for example the date, then exit install_assist properly
3. Reboot the system
After that daemon process in /etc/inittab started, CRS installation completed.

2.2 文档二：

Clusterware Fails To Start DuringRoot.sh -- "Failure at final check of Oracle CRS stack 10" [ID329450.1]

The Oracle Clusterware runs as root, but for some operations itneed to run as the oracle user, and uses the "su -l" which invokesthe oracle user shell login/profile script. If that shell profile script hasinteractive or cpu bound operations or prompts this may affect theClusterware operation.

--这边文档说的是.bash_profile中的参数有交互性的参数，删除这些参数就可以了。

三．问题分析

查看相关log：

[oracle@rac1 client]$ pwd

/u01/app/10.2.0/grid/log/rac1/client

[oracle@rac1 client]$ ls

clscfg_6337.log clsc.log css.log ocrconfig_6285.log

--在一个节点用root执行如下命令，清除OCR上的信息：

[root@rac1 ~]# sh /u01/app/10.2.0/grid/install/rootdeinstall.sh

Removing contents from OCR mirror device

Removing contents from OCR device

2560+0 records out

10485760 bytes (10 MB) copied, 1.18886 s,8.8 MB/s

然后在运行root.sh 问题依旧。

尝试使用了如下方法：

1. 关闭防火墙

我在安装之前已经把防火墙关闭，所以这里只是检查一下。

[root@rac1 tmp]# service iptables status

iptables: Firewall is not running.

[root@rac1 tmp]# chkconfig iptables --list

iptables 0:off 1:off 2:off 3:off 4:off 5:off 6:off

2. 注释了如下文件：

[root@rac1 tmp]# cat /etc/pam.d/other

#%PAM-1.0

auth required pam_deny.so

account required pam_deny.so

password required pam_deny.so

session required pam_deny.so

3. 删除相关socket：

# rm -f /usr/tmp/.oracle/*

# rm -f /tmp/.oracle/*

# rm -f /var/tmp/.oracle/*

Unable To Connect To Cluster ManagerOra-29701 as Network Socket Files are Removed [ID 391790.1]

运行sh/u01/app/10.2.0/grid/install/rootdeinstall.sh清除后再次安装，问题依旧，可能还是兼容性的问题。

后来把OS换成Redhat 5.4，成功安装了，可能还是Oracle 10g在Oracle Linux 6上的兼容性问题，在Oracle Linux 6上，我测试过Oracle 11.2.0.3的RAC，安装没有问题。
