Table to Display db time from AWR

Expert Oracle Database Tips by Donald BurlesonMarch 31, 2015


Question:  I would like to get db time percentage for every sql_id as I can see in AWR report.  Is there a way to get this db time information from the AWR?

Answer:  :  The db time metric is the amount of elapsed time spent performing Database user-level calls.  

The db time percentage for a SQL statement indicates the cumulative time that is spent processing user requests, so the db time percentage is a system metric.  

For a SQL statement, the db time does not really apply because db time is a system-level metric:

Statistic Name                     Time (s) Percent of Total DB Time
---------------------------------- -------- ------------------------
DB time                                 169
sql execute elapsed time                156                       93
DB CPU                                  153                       90
PL/SQL execution elapsed time            77                       46
background cpu time                      53                       31
parse time elapsed                        6                        4
hard parse elapsed time                   4                        3
connection management call elapsed time   0                        0

Normally, DB time is displayed in the v$sess_time_model and v$sys_time_model views, and for historical SQL, any SQL ID has execution statistics in the dba_hist_sqlstat table.

However, to display db time, you may want to join dba_hist_sqlstat into dba_hist_sys_time_model:

select . . . .
  stat_name = 'db time'
and . . .;

If you want to download a pre-tested working script to display details for SQL in AWR, see the Oracle script collection.
