I have the following problem:
When I create an awr report within two snapshots say 24139 and 24140 , I get from the part of "SQL ordered by Elapsed Time" the following information:
SQL ordered by Elapsed Time DB/Inst: DEVC/DEVC Snaps: 24139-24140
-> Resources reported for PL/SQL code includes the resources used by all SQL
statements called by the code.
-> % Total DB Time is the Elapsed Time of the SQL statement divided
into the Total Database Time multiplied by 100
Elap per %
So far so good.
The problem is that I want to retrieve the same information from the DBMS_SQLTUNE.SELECT_WORKLOAD_REPOSITORY for the same snapshot interval I get:
exec dbms_sqltune.create_sqlset ('MYSQLSET2');
OPEN cur FOR
DBMS_SQLTUNE.LOAD_SQLSET(sqlset_name => 'MYSQLSET2',
populate_cursor => cur);
When I query the information I realize that nothing matchs with the AWR report (for example , the same sql_id as different number of executions)
SQL> SELECT sql_id,elapsed_time,cpu_time,executions, round(((elapsed_time/1000000)/decode(executions, 0, 1, executions))
2 'MYSQLSET2', -- sqlset_name
3 NULL, -- basic_filter
4 NULL, -- object_filter
5 NULL, -- ranking_measure1
6 NULL, -- ranking_measure2
7 NULL, -- ranking_measure3
8 NULL, -- result_percentage
9 NULL) -- result_limit
11 where sql_id ='dccxnr2d9b3xd'
12 order by 2 desc;
SQL_ID /ELAPSED_TIME /CPU_TIME /EXECUTIONS /RATIO
dccxnr2d9b3xd / 63592931 / 62241266 / 3 / 21.2
Does anyone have an ideia why the values are different while query the same repository?
I need to retrieve the correct information and I don't know which of the sources I should rely.
Thank you in advance for any help
