-- 使用 runcluvfy 校验Oracle RAC安装环境
--*****************************************
所谓工欲善其事，必先利其器。安装 Orale RAC 可谓是一个浩大的工程，尤其是没有做好前期的规划与配置工作时将导致安装的复杂
度绝非想象。幸好有runcluvfy工具，这大大简化了安装工作。下面的演示是基于安装Oracle 10g RAC / Linux来完成的。
1.从安装文件路径下使用runcluvfy实施安装前的校验

信息，这是一个bug，Metalink中有详细说明，doc.id:338924.1。参考本文尾部列出的内容。
对于上面描述的failed的包，尽可能的将其安装到系统。
2.安装Clusterware 后的检查,注意，此时执行的cluvfy是位于已安装的路径
[oracle@node1 ~]$ pwd
/u01/app/oracle/product/10.2.0/crs_1/bin
[oracle@node1 ~]$./cluvfy stage -post crsinst -n node1,node2
Performing post-checks for cluster services setup
Checking node reachability...

Cluster manager integrity check passed.
Checking cluster integrity...
Cluster integrity check passed
Checking OCR integrity...
Checking the absence of a non-clustered configuration...
All nodes free of non-clustered, local-only configurations.
Uniqueness check for OCR device passed.
Checking the version of OCR...
OCR of correct Version "2" exists.
Checking data integrity of OCR...
Data integrity check for OCR passed.
OCR integrity check passed.
Checking CRS integrity...
Checking daemon liveness...
Liveness check passed for "CRS daemon".
Checking daemon liveness...
Liveness check passed for "CSS daemon".

Checking existence of VIP node application (required)
Check passed.
Checking existence of ONS node application (optional)
Check passed.

Check passed.
Post-check for cluster services setup was successful.
从上面的校验可以看出，Clusterware的相关后台进程，nodeapps相关资源以及OCR等处于passed状态，即Clusterware成功安装

4.ID 338924.1
CLUVFY Fails With Error: Could not find a suitable set of interfaces for VIPs [ID 338924.1]
________________________________________
Modified 29-JUL-2010 Type PROBLEM Status PUBLISHED

________________________________________
Applies to:
Oracle Server - Enterprise Edition - Version: 10.2.0.1 to 11.1.0.7 - Release: 10.2 to 11.1
Information in this document applies to any platform.
Symptoms
When running cluvfy to check network connectivity at various stages of the RAC/CRS installation process, cluvfy fails
with errors similar to the following:
=========================
Suitable interfaces for the private interconnect on subnet "10.0.0.0":
node1 eth0:10.0.0.1
node2 eth0:10.0.0.2
Suitable interfaces for the private interconnect on subnet "192.168.1.0":
node1_internal eth1:192.168.1.2
node2_internal eth1:192.168.1.1
ERROR:
Could not find a suitable set of interfaces for VIPs.
Result: Node connectivity check failed.
========================
On Oracle 11g, you may still see a warning in some cases, such as:
========================
WARNING:
Could not find a suitable set of interfaces for VIPs.
========================
Output seen will be comparable to that noted above, but IP addresses and node_names may be different - i.e. the node names
of 'node1','node2','node1_internal','node2_internal' will be substituted with your actual Public and Private node names.
A second problem that will be encountered in this situation is that at the end of the CRS installation for 10gR2, VIPCA
will be run automatically in silent mode, as one of the 'optional' configuration assistants. In this scenario, the VIPCA
will fail at the end of the CRS installation. The InstallActions log will show output such as:
> />> Oracle CRS stack installed and running under init(1M)
> />> Running vipca(silent) for configuring nodeapps
> />> The given interface(s), "eth0" is not public. Public interfaces should
> />> be used to configure virtual IPs.
Cause
This issue occurs due to incorrect assumptions made in cluvfy and vipca based on an Internet Best Practice document -
"RFC1918 - Address Allocation for Private Internets". This Internet Best Practice RFC can be viewed here:
http://www.faqs.org/rfcs/rfc1918.html
From an Oracle perspective, this issue is tracked in BUG:4437727
Per BUG:4437727, cluvfy makes an incorrect assumption based on RFC 1918 that any IP address/subnet that begins with any
of the following octets is private and hence may not be fit for use as a VIP:
172.16.x.x through 172.31.x.x
192.168.x.x
10.x.x.x
However, this assumption does not take into account that it is possible to use these IPs as Public IP's on an internal
network (or intranet). Therefore, it is very common to use IP addresses in these ranges as Public IP's and as Virtual
IP(s), and this is a supported configuration.
Solution
The solution to the error above that is given when running 'cluvfy' is to simply ignore it if you intend to use an IP in
one of the above ranges for your VIP. The installation and configuration can continue with no corrective action necessary.
One result of this, as noted in the problem section, is that the silent VIPCA will fail at the end of the 10gR2 CRS
installation. This is because VIPCA is running in silent mode and is trying to notify that the IPs that were provided
may not be fit to be used as VIP(s). To correct this, you can manually execute the VIPCA GUI after the CRS installation
is complete. VIPCA needs to be executed from the CRS_HOME/bin directory as the 'root' user (on Unix/Linux) or as a
Local Administrator (on Windows):
$ cd $ORA_CRS_HOME/bin
$ ./vipca
Follow the prompts for VIPCA to select the appropriate interface for the public network, and assign the VIPs for each node
when prompted. Manually running VIPCA in the GUI mode, using the same IP addresses, should complete successfully.
Note that if you patch to 10.2.0.3 or above, VIPCA will run correctly in silent mode. The command to re-run vipca
silently can be found in CRS_HOME/cfgtoollogs (or CRS_HOME/cfgtoollogs) in the file 'configToolAllCommands' or
'configToolFailedCommands'. Thus, in the case of a new install, the silent mode VIPCA command will fail after the
10.2.0.1 base release install, but once the CRS Home is patched to 10.2.0.3 or above, vipca can be re-run silently,
without the need to invoke the GUI tool

上面的描述很多，下面给出处理办法
在出现错误的节点修改vipca 文件
[root@node2 ~]# vi $CRS_ORA_HOME/bin/vipca
找到如下内容：
Remove this workaround when the bug 3937317 is fixed
arch=`uname -m`
if [ "$arch" = "i686" -o "$arch" = "ia64" ]
then
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
fi
#End workaround
在fi 后新添加一行：
unset LD_ASSUME_KERNEL
以及srvctl 文件
[root@node2 ~]# vi $CRS_ORA_HOME/bin/srvctl
找到如下内容：
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
同样在其后新增加一行：
unset LD_ASSUME_KERNEL
保存退出，然后在故障重新执行root.sh
