Dynamic. Scope = ALTER SYSTEM. 

0 

0 to number of user licenses 

Multiple instances should have the same values. If different instances specify different values for this parameter, the value of the first instance to mount the database takes precedence. 

LICENSE_MAX_USERS specifies the maximum number of users you can create in the database. When you reach this limit, you cannot create more users. You can, however, increase the limit.

Do not enable both concurrent usage (session) licensing and user licensing. Set either LICENSE_MAX_SESSIONS or LICENSE_MAX_USERS to zero.
