Parameter type


Default value


Parameter class


Range of values

0 to number of session licenses

Real Application Clusters

Multiple instances can have different values, but the total for all instances mounting a database should be less than or equal to the total number of sessions licensed for that database.

LICENSE_MAX_SESSIONS specifies the maximum number of concurrent user sessions allowed. When this limit is reached, only users with the RESTRICTED SESSION privilege can connect to the database. Users who are not able to connect receive a warning message indicating that the system has reached maximum capacity.

A zero value indicates that concurrent usage (session) licensing is not enforced. If you set this parameter to a nonzero number, you might also want to set LICENSE_SESSIONS_WARNING (see "LICENSE_SESSIONS_WARNING").

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