~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-- Explanation:
--   In the "Activity Over Time" section of the ASH report,
--   the analysis period is divided into smaller slots
--   and top wait events are reported in each of those slots.
-- Default:
--   The analysis period will be automatically split upto 10 slots
--   complying to a minimum slot width of
--     1 minute, if the source is V$ACTIVE_SESSION_HISTORY or
--     5 minutes, if the source is DBA_HIST_ACTIVE_SESS_HISTORY.
Specify Slot Width in seconds to use in the "Activity Over Time" section:
Defaults to a value as explained above:

Specify Report Targets （using ashrpti.sql） to generate the ASH report
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-- Explanation:
--   ASH Report can accept "Report Targets",
--   like a particular SQL statement, or a particular SESSION,
--   to generate the report on. If one or more report targets are
--   specified, then the data used to generate the report will only be
--   the ASH samples that pertain to ALL the specified report targets.
-- Default:
--   If none of the report targets are specified,
--   then the target defaults to all activity in the database instance.
