Solaris 10下迁移10G RAC (四)

最近做了一个rac数据库的迁移，中间涉及到很多部分内容，包括rac环境的搭建、ASM的设置、数据库的迁移、升级等。
本文是这次迁移工作的第四部分：安装数据库软件。

4 安装数据库软件

安装完clusterware后，就可以进行安装数据库的操作了。

Pre-check for database installation was unsuccessful on all the nodes.

从返回的信息来看，失败的地方可以分为两个部分：

第一部分是包检测失败，这个原因在前面已经讲过了，不会影响安装，可以忽略。

第二部分是系统内核参数检测有问题，实际上我已经在/etc/system中设置了相关的内核参数，并且已经生肖，我估计是因为solaris10中，runcluvfy.sh检测的是资源控制器中设置的参数，而不是/etc/system中设置的参数，所以会报错。如果你确定已经正确地在/etc/system中设置了合理的参数，则这个错误问题不大，不会影响安装。

4.2正式开始安装oracle software

在pre1上以root执行：

# xhost +

access control disabled, clients can connect from any host

# su - oracle

Sun Microsystems Inc. SunOS 5.10 Generic January 2005

$ bash

bash-3.00$ export DISPLAY=172.0.2.1:1.0

bash-3.00$ cd /backup/soft/database/

bash-3.00$ ls

10gr2_db_sol.cpio install runInstaller welcome.html

doc response stage

bash-3.00$ ./runInstaller

在界面中选择自定义安装、下一步，选择oracle主目录

下一步，选择需要安装的节点，这里把所有节点都选择（pre1），

下一步，选择需要安装的组件

下一步，oracle进行一系列的检查，都通过后点击下一步

选择系统组（dba）

下一步，选择安装内容，这里需要用ASM，所以选择第二项，oracle会自动先安装oracle software，然后再安装ASM。

下一步，开始安装，oracle在第一个节点安装结束后，会自动把文件拷贝到其他节点中。

安装完软件后，需要配置监听，配置完监听后，oracle会自动运行dbca，配置ASM，

输入sys密码，

设置参数文件的路径，因为现在还没有共享存储，故选择第一个IFILE，注意把路径修改至：

$ORACLE_HOME/dbs/init+ASM.ora

下一步，oracle开始创建ASM实例，实例创建完毕后，进入ASM DISKGROUP设置界面：

输入DISK GROUP名称：DATA

选择外部冗余

在/dev/rdsk/c3t0d0s6、/dev/rdsk/c3t0d2s6前打勾，把这两个分区作为ASM磁盘组的磁盘，点击下一步创建磁盘组。

下一步，点击finish。

Oracle还会弹出一个界面要求建库，这里打算用其他地方恢复一个数据库到本地，所以直接选择cancel，

最后需要在所有节点以root用户执行一个脚本：

bash-3.00# /oracle/app/product/10.2/database/root.sh

Running Oracle10 root.sh script...

The following environment variables are set as:

ORACLE_OWNER= oracle

ORACLE_HOME= /oracle/app/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.

至此，oracle软件安装完毕。
