安裝Oracle 10.2.0.5 RAC for AIX6（二）

簡單介紹在AIX6上安裝10.2.0.5 RAC的過程。

這一篇描述CLUSTER的建立。

上一篇進行了安裝的準備工作，下面開始安裝CLUSTER，首先需要執行rootpre.sh：

# cd /home/oracle/software/clusterware/Disk1/
# cd install
# cd rootpre
# ./rootpre.sh
./rootpre.sh output will be logged in /tmp/rootpre.out_11-04-15.00:09:02
Saving the original files in /etc/ora_save_11-04-15.00:09:02....
Copying new kernel extension to /etc....
Loading the kernel extension from /etc

Oracle Kernel Extension Loader for AIX
Copyright (c) 1998,1999 Oracle Corporation

Successfully loaded /etc/pw-syscall.64bit_kernel with kmid: 0x512c3000
Successfully configured /etc/pw-syscall.64bit_kernel with kmid: 0x512c3000
The kernel extension was successfuly loaded.

Configuring Asynchronous I/O....
Asynchronous I/O is not installed on this system.
You will need to install it, and either configure it yourself using
'smit aio' or rerun the Oracle root installation procedure.

Configuring POSIX Asynchronous I/O....
Posix Asynchronous I/O is not installed on this system.
You will need to install it, and either configure it yourself using
'smit aio' or rerun the Oracle root installation procedure.

Checking if group services should be configured....
Nothing to configure.

下面執行runInstaller，開始CLUSTER的安裝，這個過長和其他平臺下的CLUSTER安裝沒有區別，這裡就不詳細描述了，基本上圖形介面上的說明已經可以幫助順利完成CLUSTER的安裝。

安裝完成後，兩個節點分別執行orainstRoot.sh：

# /opt/oracle/oraInventory/orainstRoot.sh
Changing permissions of /opt/oracle/oraInventory to 775.
Changing groupname of /opt/oracle/oraInventory to oinstall.

在節點1上執行root.sh：

# /opt/oracle/product/10.2/crs/root.sh

Running vipca(silent) for configuring nodeapps
The given interface(s), "en0" is not public. Public interfaces should be used to configure virtual IPs.

這個錯誤以前碰到過多次了，Oracle將PUBLIC的interface認為是private的，導致無法配置vip。透過手工啟動vipca圖形介面來進行配置vip，這個過程就不再重複了。Vip配置成功後，CLUSTER環境的安裝順利完成。
