‘Multi-server’ domain may require more management
Last time we looked at the right way to approach Named User licensing—by counting individual people and devices that access Oracle software.
What happens when you have a number of systems and a set of Named Users? Does each user require a license for each system? Also, what about user minimums?
Let’s look at what a Named User license actually allows that user to do. The majority of Named User metrics (with notable exception of the old Named User Single Server license) allows a single licensed user to access that software on any server.
An excellent example of users who could benefit from this, and that have access to many systems, are database administrators. They will probably need to access every database server in an Oracle estate. They really only need one Named User Plus license for this privilege.
So, each Named User only needs a single license and then they can access any Oracle database in your organisation?
Not so fast. There’s an important caveat to this: any server licensed by Named User must be correctly licensed. This means means that the number of Named User licenses allocated to that server must be the greater of the Named User ‘minimum’ (see below) or the actual Named User population taking users with access to more than one system into account. Your users must also be licensed for the correct products they will access on that server. We’ll come to that in a moment.
When you think about it, this minimum complicates the Named User metric. It is not just a metric based on users, it is also related to servers and the products on those servers.
The diagram below shows a simple example with three systems running Oracle Enterprise Edition database. For each system, I have shown the actual users who can access it, and considered if there is any overlap of users between systems. In this case, 100 users of System A can also use System B—these users therefore do not need further license beyond the license they are allocated for System A. At all times, you have to consider which is the greater number—your user population or the minimums required, and you must purchase the greater of the two.
