测试安装三节点Oracle 12C RAC，笔记本配置双核I5 16g内存，每台虚机分配4G 内存。

在数据库软件安装过程中，主实例异常重启，重新安装数据库软件，但是遇到报错。报错如下：

[INS-32025] The chosen installation conflicts with software already installed in the givenoraclehome.

处理方法如下：

1.修改inventory文件

[root@rac01 ContentsXML]# less inventory.xml

<?xml version="1.0" standalone="yes" ?>

</VERSION_INFO>

<HOME_LIST>

<HOME NAME="OraGI12Home1" LOC="/u01/12.2.0/grid" TYPE="O" IDX="1" CRS="true"/>

<HOME NAME="OraDB12Home1" LOC="/u01/app/oracle/product/12.2.0/db_1" TYPE="O" IDX="2"/>--删除掉这一行，保存退出

</INVENTORY>

2.重新启动安装程序

[root@rac01 ~]# su - oracle

<rac01:orcl1:/home/oracle>$ls

database linuxx64_12201_database.zip

<rac01:orcl1:/home/oracle>$cd database

<rac01:orcl1:/home/oracle/database>$./runInstaller
