才能是来自独创性。独创性是思维、观察、理解和判断的一种独特的方式。
系统环境：
操作系统：Solaris 10（x86-64）
Cluster： Oracle GRID 11.2.0
Oracle： Oracle 11.2.0.1.0
如图所示：RAC 系统架构
对于Oracle 11G构建RAC首先需要构建GI(Grid Infrastructure)的架构
三、安装相关软件和补丁包（所有node）
1、检查软件包：
[root@node2:/]# pkginfo -i SUNWarc SUNWbtool SUNWhea SUNWlibm SUNWlibms SUNWsprot SUNWtoo SUNWi1of SUNWi1cs SUNWi15cs SUNWxwfnt

system SUNWi1of ISO-8859-1 (Latin-1) Optional Fonts
system SUNWlibm Math & Microtasking Library Headers & Lint Files (Usr)
system SUNWlibms Math & Microtasking Libraries (Usr)
system SUNWsprot Solaris Bundled tools
system SUNWtoo Programming Tools
system SUNWxwfnt X Window System platform required fonts
ERROR: information for "SUNWi1cs" was not found

[root@node2:/]# pkginfo -i SUNWi1cs SUNWi15cs
system SUNWi15cs X11 ISO8859-15 Codeset Support

4、系统补丁需求：
四、建立主机间信任关系（所有node）
在Solaris 10通过RSH系列工具，可以建立主机间的信任关系。

[root@node1:/]# svcadm enable svc:/network/rexec:default
[root@node1:/]# svcadm enable svc:/network/shell:default

五、配置时间同步（所有node）
对于Oracle 11gR2中，可以采用Oracle Cluster Time Synchronization daemon (ctssd) 服务，来进行时间的同步，不需要采用系统的NTP服务进行同步，需要关闭系统的NTP服务。

----默认已经被关闭
