在AIX 5.3+HACMP 5.4以上环境安装10gR2 10.2.0.1 RAC CRS Clusterware必须先运行Patch 6718715中的rootpre.sh，若不运行该rootpre.sh则会导致后续的诸多问题，例如：

1. 在 “Cluster Node Information” or “Specify Cluster Configuration” 2个界面窗口中无法点击灰色的ADD NODE按钮:

AIX: "Cluster Node Information" or "Specify Cluster Configuration" Window Does not Show Any Node and "Add" Button is Greyed Out

Oracle Server - Enterprise Edition - Version: 10.2.0.1 and later   [Release: 10.2 and later ]
IBM AIX on POWER Systems (64-bit)
Symptoms

Installing Oracle Clusterware (CRS or 11gR2 Grid Infrastructure), "Cluster Node Information" or "Specify Cluster Configuration" window does not show any node and "Add" button is greyed out:

Installation log

[main] [10:21:20:345] [sQueryCluster.isCluster:74]  LKMGR file =/usr/sbin/cluster/utilities/cldomain
[main] [10:21:20:346] [QueryCluster.:49]  Detected Cluster
[main] [10:21:20:346] [QueryCluster.isCluster:65]  Cluster existence check = true

Cause

The cause is IBM HACMP (or PowerHA) executable was not removed cleanly when HACMP was deinstalled. After HACMP was deinstalled, "ls" still shows one HACMP command:

$ ls -l /usr/sbin/cluster/utilities/cldomain
lrwxrwxrwx    1 root     system           29 Sep 21 13:54 /usr/sbin/cluster/utilities/cldomain -> /opt/VRTSvcs/rac/bin/cldomain

Oracle OUI depends on /usr/sbin/cluster/utilities/cldomain to determine if vendor clusterware exists, if so, it will install on top of HACMP and get list of nodes from HACMP.

In this case, since HACMP executable is detected, OUI will not allow user to manually enter node information, however, since HACMP was deinstalled, it does not have any node membership information.

Solution

The solution is to remove /usr/sbin/cluster/utilities/cldomain from all nodes and restart OUI.

2. 运行root.sh时显示ocrconfig.bin无法加载必要的库文件，或者干脆root.sh运行失败 ，显示Failed to start Oracle Clusterware stack;

由于10g CRS对于AIX HACMP有较多的依赖关系所以 随10.2.0.1附带的rootpre.sh无法有效配置oracle用户的HA信息，所以必须先下载Patch 6718715: SUPPORT FOR HACMP 5.4 IN ROOTPRE.SH SCRIPT FOR 版本10.2.0.3，否则10.2.0.1 CRS将无法正常安装。

Product : 	Oracle Database Server 10GR2 (10.2.0.x)

Bug     :       6718715 - Support HACMP 5.4

Platforms: AIX 5L (5.x), AIX 6.x

Steps to apply the patch
------------------------
1--> Login as root user 
2--> Unpack the files shipped in this patch in a temporary directory
3--> Run the rootpre.sh script
     ./rootpre.sh

Note: 
 This patch supercedes any rootpre.sh shipped with the aforementioned 
 Oracle products.
