RAC 安装DB 软件runInstaller 看不到节点 解决方法，racruninstaller
Clusterware 安装正常，但安装Oracle 软件的时候，runInstaller 看不到节点信息：
[grid@rac1 bin]$ crs_stat -t

[grid@rac1 bin]$
导致这种现象的原因是因为Clusterware 的Inventory信息不准确，重新更新一下即可。
解决方法:
切到GRID用户，进入$ORACLE_HOME/bin
[grid@rac1 bin]$ pwd
/u01/gridsoft/11.2.0/oui/bin
[grid@rac1 bin]$ ls
addLangs.sh attachHome.sh filesList.bat filesList.sh resource runInstaller runSSHSetup.sh
addNode.sh detachHome.sh filesList.properties lsnodes runConfig.sh runInstaller.sh
[grid@rac1 bin]$
--更新inventory：
[grid@rac1 bin]$ ./runInstaller -silent -ignoreSysPrereqs -updateNodeList ORACLE_HOME="/u01/gridsoft/11.2.0" LOCAL_NODE="rac1" CLUSTER_NODES="{rac1,rac2}" CRS=true
Starting Oracle Universal Installer...
Checking swap space: must be greater than500 MB. Actual 15999 MB Passed
The inventory pointer is located at/etc/oraInst.loc
The inventory is located at/u01/oraInventory
'UpdateNodeList' was successful.
恢复正常。
