A session is a specific connection of a user to an Oracle instance through a user process. For example, when a user starts SQL*Plus, the user must provide a valid user name and password, and then a session is established for that user. A session lasts from the time the user connects until the time the user disconnects or exits the database application.
当你连到数据库是SQL*Plus给你建立一个数据库会话，当你断掉连接是会话将会断掉。要想连接到数据库必须有建立会话的权限。
