Specify Slot Width (using ashrpti.sql) for 'Activity Over Time' section
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


-- Explanation:
--   In the 'Activity Over Time' section of the ASH report,

--   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:
