在Solaris 10 X86上安装Oracle 10g RAC详解 (2)

6,接下来就进入到安装界面，可以看到Oracle安装到了所有节点



同样，安装后期会提示用户在所有节点上以root身份运行脚本root.sh,这时在RAC1运行是还要进行VIP配置。
/u01/app/oracle/product/10.1.0.3/oracle/root.sh
Running Oracle10 root.sh script...
The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /u01/app/oracle/product/10.1.0.3/oracle
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 ...
Adding entry to /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.
此时Oracle安装程序会进行VIP配置，需要选择网络接口和各个节点的虚拟地址




配置完成后会出现显示整个配置的结果：



同时需要在另一个节点RAC2上运行root.sh
/u01/app/oracle/product/10.1.0.3/oracle/root.sh
Running Oracle10 root.sh script...
The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /u01/app/oracle/product/10.1.0.3/oracle
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...
Adding entry to /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.
CRS resources are already configured
以上步骤完成后，整个Oracle 10g的安装就完成了。



下面我们还需要进行Oracle网络服务的配置，具体步骤如下：
netca
Oracle Net Services Configuration:
1, 在网络服务配置时选择”Cluster configuration”,如下图所示：



2,选中需要进行配置的节点，这里选中RAC1和RAC2。



3,以后的配置可以按照缺省项一步步进行，最后直到配置成功完成。
1,在创建数据库之前，我们还需要添加一个Oracle的补丁4186426,这个补丁解决了启动Oracle实例时会失败的错误，用户可以从http://metalink.oracle.com上得到这一补丁,需要注意的是安装这个补丁时要按照它提供的步骤进行，这里不做详述.
在所有节点上创建数据库

1，由于创建oracle数据库需要多个raw devices,这里为了方便起见，将这些raw devices的设备文件连接成更易懂的文件名,同时需要设置相应的属主和权限，具体步骤如下：
cd ORACLE
mkdir db
chown oracle:root db
cd db
ls
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C800d0s0 system
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C800d0s1 sysaux
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C800d0s3 undotbs1
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C800d0s4 undotbs2
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C800d0s5 temp
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C801d0s0 example
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C801d0s1 users
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C801d0s3 redo1_1
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C801d0s4 redo1_2
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C801d0s5 redo2_1
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C801d0s6 redo2_2
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C801d0s7 spfile
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C802d0s3 control1
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C802d0s4 control2
ln -s /dev/rdsk/c3t600C0FF00000000007D35237AD84C802d0s5 pwdfile
pwd
/ORACLE/db
chown -RL oracle:dba *
chmod -R 660 *
将以上的目录做为创建数据库所需raw devices的配置文件，具体步骤为：
mkdir -p /u01/app/oracle/oradata/tree
并在此目录下创建文件tree_raw.conf,具体内容如下：
cat tree_raw.conf
system=/ORACLE/db/system
sysaux=/ORACLE/db/sysaux
example=/ORACLE/db/example
users=/ORACLE/db/users
temp=/ORACLE/db/temp
undotbs1=/ORACLE/db/undotbs1
undotbs2=/ORACLE/db/undotbs2
redo1_1=/ORACLE/db/redo1_1
redo1_2=/ORACLE/db/redo1_2
redo2_1=/ORACLE/db/redo2_1
redo2_2=/ORACLE/db/redo2_2
control1=/ORACLE/db/control1
control2=/ORACLE/db/control2
spfile=/ORACLE/db/spfile
pwdfile=/ORACLE/db/pwdfile
然后编辑文件/export/home/oracle/.profile,将以下几列加入
DBCA_RAW_CONFIG=/u01/app/oracle/oradata/tree/tree_raw.conf
export DBCA_RAW_CONFIG
2，在各节点上分别设置环境变量
RAC1,
ORACLE_SID=tree1
export ORACLE_SID
RAC2,
ORACLE_SID=tree2
export ORACLE_SID
3,和安装Oracle数据库一样，需要将节点RAC1和RAC2上的另一个CPU离线，可参照安装Oracle数据库一节中的步骤来做。
=====================================================

以oracle用户来创建一个Cluster数据库，具体步骤如下：

dbca
创建数据库步骤：
1,选择数据库的类型,这里需要选择创建Oracle Real Application Clusters database

然后选择创建一个数据库并随后在节点选择时选中两个节点RAC1和RAC2.
4,在选择模板时，这里选择创建”General Purpose”的数据库。
5,随后按照提示输入全局数据库的名字，这里设定名字为”tree”

6,在随后的数据库管理选项中选取Oracle Enterprise Manager Grid Control,即不选中”Configure the Database with Enterprise Manage”的选项

以后的步骤中需要设定密码，设定存储和恢复机制以及数据库内容和服务，这里按照缺省值设定即可。
随后要设置数据库的初始参数，在此，根据机器的内存大小，设定SGA为800M，PGA 为200M，用户可根据具体的环境来设定相应的大小

接下来需要配置数据库的存储并设置创建数据库的一些选项,所有这些设置完成后，就开始创建数据库，最终顺利建立，见下图：

在此我们还可以来起动并验证一下刚刚创建的数据库
