前一阵刚刚才测试环境下装完Solaris 8下的ORACLE RAC。结果发现这次采购的F490硬件居然不支持Solaris 8。只好将操作系统升级到Solaris 10。

前面已经对Solaris 8下的安装进行了比较详细的描述，这里只是简单记录一下Solaris 10下的安装步骤。和8类似的步骤会简单带过。

这篇介绍Oracle Clusterware的安装过程。

RAC安装的准备工作可以参考：Solaris10下安装Oracle10203RAC环境（一）：http://yangtingkun.itpub.net/post/468/276589

首先，解开CLUSTERWARE压缩包：

$ gunzip 10gr2_cluster_sol.cpio.gz
$ cpio -idmv < 10gr2_cluster_sol.cpio$ gunzip 10gr2_cluster_sol.cpio.gz
$ cpio -idmv < 10gr2_cluster_sol.cpio

建立安装所需的目录：

$ mkdir -p /data/oracle/product/10.2
$ mkdir /data/oracle/oraInventory
$ mkdir /data/oracle/product/10.2/crs
$ mkdir /data/oracle/product/10.2/database

建立ocr和voting disk所需的裸设备，使用Veritas的Volumn Manager建立所需的裸设备：

root@ahrac1 # cd /dev/vx/rdsk/datadg
root@ahrac1 # vxassist make ocr 300m
root@ahrac1 # vxassist make ocr2 300m
root@ahrac1 # vxassist make vot 300m
root@ahrac1 # vxassist make vot2 300m
root@ahrac1 # vxassist make vot3 300m
root@ahrac1 # chown oracle:oinstall *

利用root登陆图形界面执行，注意，一定需要在安装之前执行ssh的验证工作，否则安装过程执行一半的时候会出现错误：Specified Nodes Are Not Clusterable。

root@ahrac1 # xhost +
access control disabled, clients can connect from any host
root@ahrac1 # su - oracle

$ exec /usr/bin/ssh-agent $SHELL

$ /usr/bin/ssh-add

Enter passphrase for /export/home/oracle/.ssh/id_dsa:

Identity added: /export/home/oracle/.ssh/id_dsa (/export/home/oracle/.ssh/id_dsa)

$ cd /data
$ cd cluster_disk
$ ./runInstaller

安装步骤中在Cluster主目录位置填入：OraCrs10g_home1和/data/oracle/product/10.2/crs信息，并选择简体中文字符。

在Cluster配置页面选择默认的Cluster name：crs，并输入节点二的信息：ahrac2、ahrac2-priv、ahrac2-vip。

在interface的选择界面：由于Oracle对于IP地址的解析存在bug，因此这里将172.25.0.0的interface类型改为PUBLIC。

在orc配置界面，输入刚才建立好的/dev/vx/rdsk/datadg/ocr和/dev/vx/rdsk/datadg/ocr2，点击确定。

在Voting disk配置界面，分别输入刚才建立好的/dev/vx/rdsk/datadg/vot、/dev/vx/rdsk/datadg/vot2和/dev/vx/rdsk/datadg/vot3，点击确定。

检查弹出的汇总信息，确认无误后，点击开始安装。

安装完成后，分别在两个节点执行下面的两个脚本：

The given interface(s), "ce0" is not public. Public interfaces should be used to configure virtual IPs.

这个错误的具体描述在Solaris8的RAC安装文档中已经详细描述了，解决方法是手工启动vipca进行配置。

root@ahrac1 # cd /data/oracle/product/10.2/crs/bin
root@ahrac1 # ./vipca

在Xmanager中启动一个终端，启动vipca图形界面。点击next，出现所有可用的网络接口，由于ce0配置的是PUBLIC INTERFACT，这里选择ce0，点击next，在出现的配置中IP Alias Name分别填入：ahrac1-vip和ahrac2-vip，IP address处填入：172.25.198.44和172.25.198.45。这里如果你的配置是正确的，那么你填完一个IP，Oracle会自动将剩下三个配置补齐。点击next，出现汇总页面，检查无误后，点击Finish。

Oracle会执行6个步骤，Create VIP application resource、Create GSD application resource、Create ONS application resource、Start VIP application resource、Start GSD application resource、Start ONS application resource。

全部成功后点击OK，结束VIPCA的配置。

这时候返回Cluster Ware的安装界面，点击OK，Oracle自动启动两个工具，并再次执行验证，顺利结束后，安装完成。
