After monitoring operating systems there might also be a wish to monitor Oracle. Of course Oracle has a bit more to offer than a database server. I will list a few links and products here that monitor the database and some that monitor other components.
First of all I want to mention the first Oracle that I was asked to monitor. It turned out to be Oracle Linux operating system. We found that this OS actually made itself known as RedHat Linux and that the SCOM discovery wizard also saw it that way. So we can pick it up as a Linux server with cross plat monitoring.
Next here are a few links to monitoring solutions for Oracle:
