Concurrent sessions

You can limit the number of concurrent sessions that are owned by a single user, and you can set different concurrent session values for each user.

A user can be limited by inherited restrictions from a group.

If the number of concurrent sessions is not set for a user, the system uses the minimum value specified for the groups to which the user belongs.
If the user or any of the groups do not have a concurrent session limit, then the number of concurrent sessions is unlimited.

For example, to set the number of concurrent sessions to 3 for user John Doe:

SYSTEM.ADMIN(ADMIN)=> CREATE USER jdoe CONCURRENT SESSIONS 3;
