3. Perform Prerequiste checks,选Ignore all;
4.安装到76%时报错：OUI-10094:Problem in saving inventory. Installation cannot continue./opt/app/oracle/orainventory/ContentsXML/comps.xml (Permission denied)
执行以下语句：
1).使用deinstall.sh删除不成功的安装;
2). 重新创建$ORACLE_HOME目录，并在该目录下Create a new oraInst.loc file:
This file should have the follow content:
inventory_loc=/opt/app/oraclegrid/product/11.2.0/grid/oraInventory
inst_group=oinstall
./runInstaller -invPtrLoc $ORACLE_HOME/oraInst.loc
The -invPtrLoc flag is used to locate the oraInst.loc file.
5.执行root.sh
6. 在update Inventory 报错了 [INS-20802] update Inventory failed. 网上说这是个dummy进程可以忽略，于是跳过;
7.此时 +ASM实例已自动创建，并自动启动，listener也自动启动，端口为1521，此时oracle database的listener不需要再启动，会zidon注册到这个listener中。

四、将数据迁移到ASM：
1.使用sys用户登录到EM，在server标签中选择Migrate to ASM，升级后所有文件都迁移到"+DATA"目录下：
+DATA/ipcdb/datafile/system.257.835737429
