Calculating Elapsed Time For Queries In Oracle

By David Fitzjarrell

There may be times when a query is taking longer to execute than expected. With Oracle, the Automatic Workload Repository collects statistics on a regular schedule to report on how the system is performing, including elapsed time for queries. Since a full AWR report may not be necessary a script using some of the AWR data can generate elapsed time reports by sql_id. Let's look at a script that does that and see how it can report longer elapsed times.

Looking at the code there is nothing unusual:


set linesize 200 trimspool on pagesize 60 verify off
column begin_interval_time format a35
column end_interval_time format a35

break on sql_id skip 1 on instance_number

column sdate new_value sdt noprint

select to_char(sysdate, 'YYYYMMDDHHMI') sdate from dual;

spool &sdt._elapsed_time_report.log

prompt 
prompt  Historic
prompt 
prompt  Elapsed by exec
prompt 

select distinct x.instance_number, x.sql_id, x.time_per_exec, x.elapsed_time_total, s.begin_interval_time, s.end_interval_time
from
(select instance_number, sql_id, snap_id,
       round((elapsed_time_total/1000000)/(case when elapseds_total = 0 then 1 else elapseds_total end),4) time_per_exec,
       round(elapsed_time_total/1000000, 4) elapsed_time_total
from dba_hist_sqlstat) x, (select snap_id, 
                                  max(begin_interval_time) begin_interval_time, 
                                  max(end_interval_time) end_interval_time
                           from dba_hist_snapshot 
                           group by snap_id) s
where s.snap_id = x.snap_id 
and x.time_per_exec > &&1
and x.time_per_exec <> x.elapsed_time_total
order by 2 asc, 3 desc, 6 desc
/

clear breaks

prompt 
prompt  Elapsed time total, current statements
prompt 

select inst_id,
       sql_id,
       elapseds,
       round(elapsed_time/1000000, 6) elapsed_sec,
       round((elapsed_time/1000000)/(case when elapseds = 0 then 1 else elapseds end), 6) elapsed_per_exec,
       last_active_time
from gv$sqlstats
where elapsed_time/1000000 > &&1
order by 4 desc
/

prompt 
prompt  Elapsed per exec, current statements
prompt 

select inst_id,
       sql_id,
       elapseds,
       round(elapsed_time/1000000, 6) elapsed_sec,
       round((elapsed_time/1000000)/(case when elapseds = 0 then 1 else elapseds end), 6) elapsed_per_exec,
       last_active_time
from gv$sqlstats
where elapsed_time/1000000 > &&1
order by 5 desc
/

set linesize 80 trimspool off

spool off

The main report, of the overall elapsed times by sql_id, is generated using a standard group by expression; since a number of readings are taken for each snap_id this is necessary to provide the overall elapsed time. One item to notice is the target time is entered when the script is called, which eliminates any statements executing in less time than the supplied lower limit. The next sections return the elapsed times for current queries and statements as total elapsed time across all executions and as elapsed time by execution; this can be helpful in determining if a total elapsed time for a given statement indicates a problem.

Let's look at a report (that's been abbreviated) that was generated by this script:

The 0-count execution lines indicate the statement hasn't completed as of the time the report is run; the latter two sections are reported from data in the GV$SQLSTATS view, which won't be updated until an execution completes.

Having such a script handy can save time and effort in troubleshooting long elapsed query times by revealing whether or not multiple executions of a statement occurred during the snapshot window and can provide a total elapsed time across snapshots so an accurate time can be obtained. And such a report can be much easier to use than a full AWR or ASH report as it isolates the elapsed time data from the rest of the repository statistics.
