这一篇描述数据库软件的建立并建立ASM实例。
在图形界面环境下进行ORACLE_HOME/oui/bin，运行addNode.sh，来进行新节点的添加过程：
$ cd $ORACLE_HOME/oui/bin
$ ./addNode.sh
Starting Oracle Universal Installer...

Oracle Universal Installer, Version 10.2.0.3.0 Production

选择需要安装的节点，这里是RACNODE3，然后点击继续：
检查汇总界面，Oracle将10.2.0.1版本和10.2.0.3补丁一起安装到新增节点上。
由于执行过程中出现了错误，需要手工执行远端脚本：
bash-3.00$ /data/oracle/product/10.2/database/oui/bin/runInstaller -attachHome -noClusterEnabled ORACLE_HOME=/data/oracle/product/10.2/database ORACLE_HOME_NAME=OraDb10g_home1 CLUSTER_NODES=racnode1,racnode2,racnode3 "INVENTORY_LOCATION=/data/oracle/oraInventory" LOCAL_NODE=racnode3
Starting Oracle Universal Installer...

The inventory pointer is located at /var/opt/oracle/oraInst.loc
The inventory is located at /data/oracle/oraInventory
'AttachHome' was successful.
同样运行updateNodeList的脚本：
bash-3.00$ /data/oracle/product/10.2/database/oui/bin/runInstaller -updateNodeList -noClusterEnabled ORACLE_HOME=/data/oracle/product/10.2/database CLUSTER_NODES=racnode1,racnode2,racnode3 CRS=false "INVENTROY_LOCATION=/data/oracle/oraInventory" LOCAL_NODE=racnode3
Starting Oracle Universal Installer...
No pre-requisite checks found in oraparam.ini, no system pre-requisite checks will be executed.
The inventory pointer is located at /var/opt/oracle/oraInst.loc
The inventory is located at /data/oracle/oraInventory
'UpdateNodeList' was successful.
运行完成后，需要在新节点上运行root.sh脚本：
# /data/oracle/product/10.2/database/root.sh
点击确定，完成软件的安装。
检查新建节点后台进程：
bash-3.00$ ps -ef|grep ora

下面在节点1上启动dbca来添加racnode3上的asm实例。
首先选项Oracle Real Application Clusters database选项，然后选择配置ASM。
在节点选择出选择全部三个节点，然后点击确定。
DBCA给出提示：ASM is present on the cluster but needs to be extended to the following nodes: [racnode3]. Do you want ASM to be extended?
确认后，dbca会在新增节点上启动ASM实例。
随后弹出对话框：
DBCA could not startup the ASM instance configured on this node. To proceed with ASM diskgroup management you need the ASM instance to be up and running. Do you want to recreate the ASM instance on this node?
确认后，dbca给出对话框输入asm实例的SYS用户密码，以及ASM实例的SPFILE和PFILE文件位置。
检查后台进程，ASM实例已经启动：
