前一阵一直在测试ORACLE 10R2的RAC环境在Solaris上的安装。碰到了很多的问题，不过最后总算成功了，这里简单总结一下安装步骤，以及碰到的问题和解决方法。

这一篇主要讨论ORACLE的软件安装。

操作系统准备工作可以参考：Solaris8上安装RAC10202环境（一）：http://yangtingkun.itpub.net/post/468/271797

Oracle的Clusterware安装过程可以参考：Solaris8上安装RAC10202环境（二）：http://yangtingkun.itpub.net/post/468/271812

在上一篇文章中已经将CLUSTERWARE软件安装完毕，下面准备安装数据库。

首先检查系统是否满足数据库的安装需求：

# su - oracle

上一篇文章已经提到了VIP的错误原因。其实现在VIP已经绑定上了，但是oracle仍然没有认出来。接着的swap空间不足的错误可以忽略，在第一篇文章中已经进行了检查，系统中有足够的swap空间。接着报了4个补丁没有打，但是系统中目前安装了这4个补丁，但是安装的版本比Oracle需要的更高，估计Oracle没有认出来。下面在对一些系统包进行检查时失败，这些包是和SunCluster有关的包，由于安装RAC准备使用Oracle的Clusterware，因此这些错误也可以忽略。最后一个错误是关于系统核心参数设置的。这写设置racnode1和racnode2完全一致，而只报了racnode2的设置有问题，怀疑是Oracle的检查程序的问题。

由于上面所有的错误都是可以忽略的，下面开始数据库的安装：将Oracle的安装文件解压，利用cpio –idmv < 10gr2_db_sol.cpio命令展开。

在安装之前，需要将已经配置好的所有裸设备授权给Oracle用户，使得Oracle用户有足够的空间来建立数据库。在racnode1上：

# chown oracle:oinstall /dev/rdsk/c2t0d0s1
# chown oracle:oinstall /dev/rdsk/c2t0d0s3
# chown oracle:oinstall /dev/rdsk/c2t0d0s4
# chown oracle:oinstall /dev/rdsk/c2t0d0s5
# chown oracle:oinstall /dev/rdsk/c2t0d0s6
# chown oracle:oinstall /dev/rdsk/c2t0d1s1
.
.
.
# chown oracle:oinstall /dev/rdsk/c2t0d5s5
# chown oracle:oinstall /dev/rdsk/c2t0d5s6
# chown oracle:oinstall /dev/rdsk/c2t0d5s7

在racnode2上：

# chown oracle:oinstall /dev/rdsk/c2t500601603022E66Ad0s1
# chown oracle:oinstall /dev/rdsk/c2t500601603022E66Ad0s3
# chown oracle:oinstall /dev/rdsk/c2t500601603022E66Ad0s4
# chown oracle:oinstall /dev/rdsk/c2t500601603022E66Ad0s5
# chown oracle:oinstall /dev/rdsk/c2t500601603022E66Ad0s6
# chown oracle:oinstall /dev/rdsk/c2t500601603022E66Ad1s1
.
.
.
# chown oracle:oinstall /dev/rdsk/c2t500601603022E66Ad5s6
# chown oracle:oinstall /dev/rdsk/c2t500601603022E66Ad5s7

下面可以开始安装了，启动Xmanager，登陆racnode1执行：

# xhost +
access control disabled, clients can connect from any host
su - oracle
Sun Microsystems Inc. SunOS 5.8 Generic Patch October 2001
$ cd /data/disk1
$ ./runInstaller

启动图形界面后，点击next。选择企业版，选择简体中文语句，点击next。

设置OraDb10g_home1，由于设置了初始化参数ORACLE_HOME，Oracle自动会将/data/oracle/product/10.2/database填入，直接点击next。

然后进入cluster安装模式，选择cluster安装，将racnode2选上，然后点击next。

系统会执行检查程序，检查是否满足安装RAC数据库的需求，检查成功后点击next。

下面有三个选择，一个是建立数据库，一个是配置Automatic Storage Management，最后是只安装软件。为了简化安装，这里选择使用ASM。因此这里选择第二个，配置ASM，并输入两次ASM实例的SYS密码。点击next。

下面是配置ASM磁盘组信息，默认Disk Group Name的名称是DATA，这里改为DISK。由于共享磁盘已经采用了RAID0这里在冗余选项处选择了Extenal。

选择所有可用的磁盘，点击next。

出现汇总页面后，点击install开始安装。

安装结束后，Oracle自动执行Oracle Net Configure Assistant工具和Oracle Database Configuration Assistant工具。

工具配置完成后，使用root在两个节点上执行root脚本：

# . /data/oracle/product/10.2/database/root.sh
Running Oracle10 root.sh script...

The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /data/oracle/product/10.2/database

Enter the full pathname of the local bin directory: [/usr/local/bin]:
Creating /usr/local/bin directory...
Copying dbhome to /usr/local/bin ...
Copying oraenv to /usr/local/bin ...
Copying coraenv to /usr/local/bin ...

Creating /var/opt/oracle/oratab file...
Entries will be added to the /var/opt/oracle/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root.sh script.
Now product-specific root actions will be performed.

点击ok，点击exit，软件安装和ASM的配置完成。
