收到一个请求，客户说安装11.2.0.2 的RAC数据库的时候，到prerequisite check这一步报错PRVF-5300和PRVF-5434。
我们可以运行下面的命令来追踪：
|
1 |
./runInstaller -debug -logLevel finest >inst1.out 2>inst2.out |
运行debug后，我们还在OUI中操作，到了prerequisite check那一步，我们看看在inst1.out的trace中写了什么：

在这里，我们看到报错的原因了，是用11.2.0.2的installer安装在11.2.0.3的crs上，所以报错，而且是在运行/oracle_grid/11.2.0/grid/bin/crsctl query crs activeversion 的时候，返回结果11.2.0.3，而installer是期望返回11.2.0.2，因此报错。这个报错根据可以忽略。见Top 11gR2 RAC Installation Issues (Doc ID 1372375.1)中：

Symptoms: PRKC-1137 : Unable to find Version object with string value 11.2.0.2.0 OR PRVF-5434 : Cannot identify the current CRS software version Possible Causes: Installing lower version of database software in higher version of Grid Infrastructure, i.e. installing 11.2.0.2 RAC in 11.2.0.3 GI cluster Solutions: Validate clusterware with "crsctl check crs" and "cluvfy stage -post crsinst -n all -verbose", if output shows no issue, ignore the error, or invoke runInstaller with -ignorePrereq option. |
