The License Style field indicates how these limits are enforced. If its value is NAMED, then you are restricted in how many active users you can enter into the database, even if they do not all use the application simultaneously. You may create more users than the license limit specifies, but the additional users cannot be active.

If the License Style value is CONCURRENT, then you may enter more active users than the license limit specifies, but your license restricts how many of them can log in to the application concurrently.

Note: The count of concurrent sessions is affected by the application server's handling of expired sessions. For example, in BEA WebLogic, the default setting for checking for expired sessions is every 60 seconds. So if you had the maximum number of concurrent users logged in, and one user's session timed out, another user wouldn't be able to log in until WebLogic cleaned up the expired session, which might be up to 60 seconds from the logout time. See WebLogic documentation for information about changing this setting (invalidation-interval-secs).

If you use the licensing scheme "Normal Users and Limited-Privilege Users", then there will be two limit fields visible and you must specify a License Style value for each limit. The two styles do not have to be the same. For example, you may wish to enforce a NAMED style for the normal user limit and a CONCURRENT style for the limited-privilege user limit.
