Top 10-20 SQL
Hi all,
I am new in this forum and also new working as DBA. Oracle 9.2.0.6 under Unix.
How will I find out the top most 20 SQL which are being fired.
Thanks a lot in advance.
Cheers
Ben
If you dont have experience with STATSPACK and your concer is just to have top 10-20 queries, with the criteria of disk_reads (physical reads), buffer_gets (logical reads), parses and etc, you can always refer v$sql, v$sqlarea,v$sql_plan_statistics_all dynamic views.
Those dynamic performance views will hold the information from time database has started and statspack report gives you the report between the snapshot time.

Equivalent for TOP 1 of SQL Server used in subqueries
Hi all,
I am trying to migrate a sql query from SQL Server to Oracle 9i, which uses the SQL Server TOP keyword in correlated subqueries.
How should I write it in Oracle?
The query is more complicated, but in principle looks like:
SELECT TAB1.t1_id, TAB2_t2_id,
ISNULL((select top 1 val_num
from values where values.val_id = TAB1.val_id ) ,0),
TAB1.date,
(select top 1 TAB3.t3_id from TAB3 where TAB3.name = TAB1.name)
FROM TAB1, TAB2
WHERE TAB1.org_id = TAB2.org_id
AND TAB1.date > TO_DATE('2006-01-01', 'YYYY-MM-DD')
TAB2.required IS NOT NULL
If I would remove in each subquery the "top 1" and add "and rownum = 1", it will not work.
Any suggestions?
Thanks,
Paulhttp://www.ispirer.com/doc/sqlways38/Output/SQLWays-1-044.html

How to get top CPU consuming sql oracle 10g
I can see the top sql by running ASH report. but there is too much infomation. is there a way I can just display TOP SQL section, and filter out other parts? this way I can use it in a shell script, and loop through the database.
or is there a query can do the ASH job?
thanks.
KarlHi,
What you will do if the EM console bug present?
As a best pratice, i will do like below
1) execute the TOP command and you see process consuming high CPU
2)
SQL> oradebug setospid <&OSPid>
SQL> oradebug tracefile_name --This will list the name of tracefile with location
SQL> oradebug unlimit
SQL> oradebug Event 10046 trace name context forever, level 12;
Let it run for 20 mins around
SQL> oradebug Event 10046 trace name context off;
SQL> exit
3) Tkprof with explain plan
4) check any plan change for that sql
Kind Regards,

hi
How can i get the top 5 or 2 users who consuming large physical and logical i/o s,like we getting the top sessions in OEM.I dont want to use OEM.Is it v$filestat and v$session?
with regards
ramyaYou can use v$sesstat and v$session. Something like :
select * from (select
b.username,
b.terminal,
to_char(b.logon_time,'dd/mm/yyyy hh24:mi:ss'),
b.program,
a.value
from v$sesstat a, v$session b
where a.statistic# in (40, 41, 42) and
b.sid = a.siD and
b.username is not null and
b.username not like 'SYS%'
order by a.value desc)
where rownum < 6;In v$statname you can see all statistics, and eventually change statistic#. -
How to find top 10 SQL statments which are consuming more cpu time.

Is there any command or script to monitor the top 10 sql statments which are consuming more cpu time.
I know by using AWR REPORT we can find it, i want the command or script to find the top cpu utilization sql statments.

Bi for a realtime scenario with SQL Server
Hi ,
i need to create a dashboard to extract data in realtime mode that means an automatic refresh of data each 1 or 2 minutes.
The dashboard must show data that are the result of the execution of SQL store Procedure in MS SQL Server 2008.
We have BI 4.1 platform SP2.
Thanks in advance for your suggestions.
Best Regards.
AndreaHi Andrea,
Create universe on top of your SQL server DB and create reports on tops of it.
Later you can use Live office / QAAWS/BIWS to fetch the Data to xcelsius dashboard.
there are few settings in Dashbaord designer which will refresh the dashboard on the refresh every option.
PF the below screenshot. -
.Don't plz send the links ... plz provide with sme solution ...
....Suppose ..i want to find TOP 3 earners of the Company so tht i can do .by using ..Inline vies.......
...My query is ..how to find ...the THIRD highest Earner of the Company .......
The Table is Employees ..Which is located in HR schema.....I don't understand what you are trying to say, sorry.
My point is:
If you know how to get the top 3 earners:
SQL> get t1
1 select v.*, rownum rn
2 from ( select *
3 from emp
4 order by sal desc
5 ) v
6* where rownum <= 3
SQL> /
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO RN
7839 KING PRESIDENT 17-NOV-81 5000 10 1
7788 SCOTT ANALYST 7566 09-DEC-82 3000 20 2
7902 FORD ANALYST 7566 03-DEC-81 3000 20 3
SQL> then it is easy to select only the 3rd row from this result set:
SQL> get t2
1 select *
2 from (
3 select v.*, rownum rn
4 from ( select *
5 from emp
6 order by sal desc
7 ) v
8 where rownum <= 3
9 ) v2
10* where v2.rn >= 3
SQL> /
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO RN
7902 FORD ANALYST 7566 03-DEC-81 3000 20 3
SQL> So I can not get your point.

Hi Gurus,
I need a whole bunch of SQL monitoring SQLs in other words some data dictionary SQL scripts to monitor SQLs like following
--Top 5 worst sqls
select c.*
from (select disk_reads, buffer_gets, rows_processed, executions,
-- address,
-- hash_value,
first_load_time, sql_text
from v$sqlarea
where parsing_user_id !=0
order by buffer_gets/decode(executions,null,1,0,1,executions) desc ) c
where rownum <= 5
order by disk_reads desc;
Thanks
Amitava.Just look at the AWR data / run an AWR report.

Hi Wang,
If you mean to look at the SQL query CR generates, then open the report in the CR Designer > Go to the Database option on the top > Click Show SQL.

Using Ranking on MS SQL Server 2005
Hello,
We are on BOXI3.1 base version and have a universe on top of MS SQL Server 2005.
My question is regarding use of rank functions. BO guides state that
You can perform a database ranking only if your database supports
it. If this is not the case, the Add a database ranking button is disabled on
the Query Panel toolbar. Databases that support ranking are Oracle, DB2,
Terradata and Redbrick.
So SQL Server is not in the list. However the add database ranking button is enabled on
my report panel. If i add a ranking the query runs for a long time and times-out.
Is there any universe parameter i need to enable to use ranking? Has any-one mangaged to
use ranking functionality with SQL Server 2005.
Thanks in advance.Hi Bashir Awan,
When we create this Object (using your example) at Universe level is the ranking hardcoded ?
My questions is, say i have Product object (with values A, B, C, D, E), and sales aggregated (10, 20, 30, 40, 50, 60, 70, 80, 90, 100)
Say the table is as follows
Product; sales
A; 10
A; 70*
B; 50
B; 20*
C; 30
C; 60*
D; 40
D; 90
E; 80
E; 100
Note: * represents Oversees sales outside US
Case 1: Now when we rank whole data to select top 3 we should get (E, D, C in Desc order)
Case 2: Now if I apply prompt on Country of sales as US will I get (E, B, D) or is it still (E, D, C as earlier).
Case 3: Similarly if I apply prompt on Product (no prompt on Country) in the filter pane and select (A, D, E) will my results show (E, D, A) or (E, D) as the value of A may be restricted due to ranking formula based on sales at Universe level.
I am sorry I may be asking a very basic question. Thanks

Expensive SQL Statements of the day?
Hi...
How can i find out Expensive SQL Statements of the day please.?
Our SAP Version is ECC 6.0 on Oracle 10.2.0.4.0
RgdsHi Srinivas,
On ECC 6.0, go to ST04 t-code --> performance --> SQL Cache --> You see SQL Statements where you need to sort by SQL Statements by Total Execution Time(ms).
I have tried on one of my R/3 4.7EE system, ST04n --> Resource COnsumption --> Top SQL Statements --> you will see 50 Top most expensive SQL Statements interms of wait time.
also Read: [Re: Diagnosis of the expensive ABAP programs having database time > 90%;
[Please Read before Posting in the Performance and Tuning Forum;
