You can add a role from inside or outside a session.
Be sure that there are no spaces or < > characters in the security role name. Security role names are case sensitive. The BEA convention is that all security role names are singular.
ALSB Console saves the role and the role becomes available immediately to all sessions. If you are in a session when you add the role and then you discard the session, ALSB Console does not delete the new role.
When you click OK to create the role, the next step is to define the conditions under which the role applies.
