在suse linux上安装10gR2 RAC问题还是很多的，这里先说下Remote ‘AttachHome’ failed on nodes错误，这个错误基本都会遇到。

这个错误提示的很明显，怎么解决已经给出了方法，只要照着做就可以了，当然图上显示的解决方法是不能直接复制的，去图上提示的log文件，在最下面可以找到命令的代码，只需要把LOCAL_NODE改成操作的节点名字就可以了，如上图，我搭建的是3节点的RAC，在安装节点(RAC31)可以找到安装日志。

SEVERE: Remote 'AttachHome' failed on nodes: 'rac32,rac33'. Refer to '/u01/app/oracle/oraInventory/logs/installActions2014-04-30_05-21-34PM.log' for details.
You can manually re-run the following command on the failed nodes after the installation:
 /u01/app/oracle/product/10.2.0/crs/oui/bin/runInstaller -attachHome -noClusterEnabled ORACLE_HOME=/u01/app/oracle/product/10.2.0/crs ORACLE_HOME_NAME=OraCrs10g_home CLUSTER_NODES=rac31,rac32,rac33 CRS=true  "INVENTORY_LOCATION=/u01/app/oracle/oraInventory" LOCAL_NODE=.

当然，执行提示的操作需要在其他节点运行，而且需要用oracle安装用户，不要使用root用户。
RAC32节点：

oracle@rac32:~> /u01/app/oracle/product/10.2.0/crs/oui/bin/runInstaller -attachHome -noClusterEnabled ORACLE_HOME=/u01/app/oracle/product/10.2.0/crs ORACLE_HOME_NAME=OraCrs10g_home CLUSTER_NODES=rac31,rac32,rac33 CRS=true  "INVENTORY_LOCATION=/u01/app/oracle/oraInventory" LOCAL_NODE=rac32
Starting Oracle Universal Installer...

No pre-requisite checks found in oraparam.ini, no system pre-requisite checks will be executed.
'AttachHome' was successful.

RAC33节点：

oracle@rac33:~> /u01/app/oracle/product/10.2.0/crs/oui/bin/runInstaller -attachHome -noClusterEnabled ORACLE_HOME=/u01/app/oracle/product/10.2.0/crs ORACLE_HOME_NAME=OraCrs10g_home CLUSTER_NODES=rac31,rac32,rac33 CRS=true  "INVENTORY_LOCATION=/u01/app/oracle/oraInventory" LOCAL_NODE=rac33
Starting Oracle Universal Installer...

No pre-requisite checks found in oraparam.ini, no system pre-requisite checks will be executed.
'AttachHome' was successful.

其他节点都运行完提示的命令，点击OK就可以继续往下操作了。
