ASH Samples in this Workload Repository schema  
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
  
Oldest ASH sample available:  03-Mar-16 23:59:55   \[  29641 mins in the past\]  
Latest ASH sample available:  24-Mar-16 14:01:18   \[  0 mins in the past\]  
  
  
Specify the timeframe to generate the ASH report  
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
Enter begin time for report:  
**--选择开始时间，这里输入的是** **03/23/16 13:13:00，时间格式是** **\[MM/DD\[/YY\]\] HH24:MI\[:SS\]，**  **默认值为15分钟之前**  
\--    Valid input formats:  
\-- To specify absolute begin time:  
\--  \[MM/DD\[/YY\]\] HH24:MI\[:SS\]  
\--  Examples: 02/23/03 14:30:15

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

Specify MODULE name (eg: from V$SESSION.MODULE) report target:

PLSQL\_ENTRY report target specified:  
  
Specify the Report Name  
**--指定报表名称，直接回车系统会自动生成名称**
