Solaris 10(x86)构建Oracle 11gR2 RAC之--配置系统环境（2）
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 SUNWarc Lint Libraries (usr) system SUNWbtool CCS tools bundled with SunOS system SUNWhea SunOS Header Files 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 ERROR: information for "SUNWi15cs" was not found
2、安装软件：
挂载Solaris 10系统安装盘
[root@node1:/]# ls /cdrom cdrom0 sol_10_910_x86 [root@node1:/cdrom/sol_10_910_x86/Solaris_10/Product]# pkgadd /cdrom/sol_10_910_x86/Solaris_10/Product SUNWi1cs pkgadd: ERROR: no packages were found in [root@node1:/cdrom/sol_10_910_x86/Solaris_10/Product]# pkgadd -d /cdrom/sol_10_910_x86/Solaris_10/Product SUNWi1cs Processing package instancefrom X11 ISO8859-1 Codeset Support(i386) 2.0,REV=2004.10.17.15.04 Copyright 2004 Sun Microsystems, Inc.

[root@node1:/cdrom/sol_10_910_x86/Solaris_10/Product]#
3、检查安装结果：
[root@node2:/]# pkginfo -i SUNWi1cs SUNWi15cs system SUNWi15cs X11 ISO8859-15 Codeset Support system SUNWi1cs X11 ISO8859-1 Codeset Support
4、系统补丁需求：
四、建立主机间信任关系（node1）
通过ssh建立信任关系
Oracle 用户：

grid 用户：
操作步骤同oracle用户相同！
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。
[root@node1:/]# svcs -a |grep ntp disabled 9:38:42 svc:/network/ntp:default disabled 9:38:43 svc:/network/ntp4:default
----默认已经被关闭
