When installing Oracle, what's the quickest way to check rpm packages and install what is  missing? When installing Oracle, there is a step which is to install all necessary packages. I use the following command to test whether a package is installed and install them if they are missing:

rpm -qa | grep binutils


I know I can verify all packages in this way, but I want to know whether there is a better and quicker way to do this task. 

Thanks.
