Oracle Study之-AIX6.1构建Oracle 11gR2 RAC(1)
环境：
操作系统： AIX 6100-09（SP3)
Cluster： HACMP6.1
集群软件： GI 11.2.0.1
数据库： Oracle 11.2.0.1
构建AIX平台下RAC 依据共享存储的使用方式可以分两种：
1、建立基于并发卷组（VG concurrent）的共享存储
2、建立基于ASM下的RAW的共享存储
由于本系统阵列（SUN T300）不支持并发存储，不具有reserve_policy或reserve_lock属性；所以在使用ASM做并发存储时，其中一个节点访问磁盘后会锁定磁盘，而另外的节点就不能再访问共享盘；所以本次环境是通过HACMP实现并发卷组的共享，然后再通过逻辑卷建立ASM DISKGOUP. 这样整个系统多了hacmp，增加了管理的复杂性。
系统架构：
本次系统架构为：AIX 6100-09(SP3)+HACMP6.1+ASM+Oracle GI + Oracle 11gR2

-------- 本次构建不使用DNS Server，所以在hosts文件解析scan ip。
二、创建配置用户
