In your test database， you find that a user’s session is executing a lot of SQL statements， resulting in the generation of a large number of trace files. While investigating the reason， you find that SQL trace has been enabled at the instance level. You want to disable SQL trace， remotely， only for that user session to reduce the volume of trace data being generated. How do you achieve this objective？（）
A
by setting the SQL_TRACE parameter to FALSE in the parameter file
B
by using DBMS_MONITOR.SESSION_TRACE_DISABLE to disable the tracing for the user session
C
by setting the SQL_TRACE parameter to FALSE by using the ALTER SYSTEM command in the user session
D
by setting the SQL_TRACE parameter to FALSE by using the ALTER SESSION command in the user session

Users of your web application have requested that they should be able to set the duration of their sessions.So for example， one user might want a webapp to stay connected for an hour rather than the webapp’sdefault of fifteen minutes； another user might want to stay connected for a whole day.
