These kinds of divisions are arbitrary. Usually, if there are too many questions in a particular category, people will sit down and try to figure out how to categorize them. So if you look in Database, you'll see not only general, but separate categories for installation and upgrade. The types of questions for installation are going to be different than for ongoing operations. Some people like to follow all of the categories, others may have particular expertise or interest. Categories can die from lack of interest, too.

One of the difference is that you can use Oracle Clusterware without RAC cluster. Oracle Clusterware can be used like any active/passive clustering solution.
