It has everything to do with user licences. A 100 named user license would allow 100 specific (named) individuals to use the system, regardless of how many are using the system simultaneously (could be 1 user or all 100). A 100 concurrent user license would allow up to 100 users to use the system simultaneously, even if you have 10,000 specific (named) users defined.
It’s a very straightforward break-even analysis. Calculate each of the following, and the smaller number wins:[list]1. Estimated number of total users times price per named user license
2. Estimated number of concurrent users times price per concurrent user license[/list]Of course the hard part is the estimates, and your confidence in those estimates. If you underestimate the number of concurrent users, they’ll be quite angry if they can’t log in. Underestimate the number of total users, and you’re leaving money on the table. Fun huh!
Named user licenses (NUL)
With NULs, you get guaranteed access to the system. Ideal for heavy users, or users that
must have access to the system (for example, quarter end reporting)
For example: for managers, executives, and analysts
Concurrent access licenses (CAL).
CALs are for casual reporting users who do not login to BO that frequently.
Most companies use a combination of NULs and CALs.
Let us say, we have 10 NULs and 40 CALs.
For example if a user is a concurrent user and logs into BI launchpad, CMC, IDT, webi rich client,
they are using up 4 concurrent sessions will open = 4 CALs
CALs are based on sessions, not users.
You have to understand how many users in you company can login at the same time to access reports.
That is the number of concurrent access licenses that you will need.
You can find the information on licenses by going to
CMC → Settings → View Global Metrics
You can also go to
CMC–> License Keys
