Top SQL's vs. Longops

I'm trying to understand the difference vs TOP SQL statement vs. what is showing up in the longops table. I pull a report showing my top 25 SQL statements but yet when I look at the long ops table the statements taking more this 1 minute are different then what shows up as my top SQL.
What should I be spending my time tuning whats in the long ops or my top SQL statements?

Top sql shows in the statspack or AWR report shows the top sql during the time period for which you run the report.
e.g if you run report for 4-5 pm,it will show the sql which consumes most resources(CPU,gets,reads etc)
V$session_longops This view displays the status of various operations that run for longer than 6 seconds (in absolute time). These operations currently include many backup and recovery functions, statistics gathering, and query execution, and more
operations are added for every Oracle release."You can also set rows in this view using the procedure dbms_application_info.set_session_longops"

sqlexecprogression_cost with the description: "sql execution progression monitoring cost threshold" and the default value of 1,000
cost = 1000 equates to elapsed time = 6 seconds

Top SQL by DB user in Oracle 10g DB Console

Is there a way to filter Top SQLs on 10g DB Console by a specific DB User? I know you can get all the SQLs by a specific user from Search Sessions, but it doesn't rank them by CPU usage. Any help is greatly appreciated.

nice idea, because SQL itself doesn't contain info about session executing it.
See Top SQL/Consumers
in OEM 10: goto Perfomance - Top Activity - here you can see Top SQLs (left side) and Top Sessions (right side) and ! if click on SQL ID from Top SQL you can see sessions executing it on Activity page.

Top sql in java enterprise manager 10G

i,
in the java enterprise manager 9i, I could use 'top sql', 'top sessions' from the java applications.
I recently installed 10G enterprise manager client, and I now miss the top sql and top sessions apps.
I know that they are available in the web interface for enterprise manager 10G, but I can't use the webinterface right now. I would like to use the standalone java enterprise manager. How can I get the top sql in there?
Greetings,
Ivo

anybody?

Sql for top sql

Dear DBAs
Application team has asked me to provide TOP Sql statements in testing database which can help them to improve code. Developer gave OEM top sql example from his last job.
Currently I do not have OEM installed. I am on 10.2.0.1.0 . I was thinking
to create a job to run sql and email everyday.
What sql can I use to generate that report ? What does OEM reports on when it show TOP Sql ?
Thanks

OEM will show you TOP sql by different catogories (each of which can be sorted) such as:
Disk Reads Per Execution
Buffer Gets Per Execution
Executions
Disk Reads
Buffer Gets
Buffer Gets Per Row
Buffer Cache Hit Ration
Sorts
Shareable memory
Rows Processed
CPU Time
Elapsed Time
Now having said that....just because the TOP sql statement is the TOP sql statement does not mean that anything needs tuned. Your developers should be examining their SQL using insite gained from reading articles and documentation.
Tuning use explain plan:

ADDM Findings Top SQL Statements

Hi,
I have run addmrpt.sql for 1 month of time using snapshots and every ADDM report says that sql statement having id **** listed under top sql statements findings and recommendation is to tune using sql tunning advisor. It has 2-4 seconds elapsed time.But when i go through AWR report instance efficiency report and all are normal.
Can anyone please confirm whether I should recommend to tune this SQL statement to my vendor ?
Thanks,
TK

below is the sql I found in ADDM. As I understood it is an intername SQL not an application SQL. When i searched it in internet found that it is related with check_oracle_health plugin. can you please help me to understand this nagios concept and the relationship it has with oracle software. And also how should I identify which methods we are using to monitor database internally?

Emailing Top SQL report metrics

I have performance monitoring configured on a database using 10g Em grid control. Is there a mechanism through which I could email the 'Top SQL' page that we get to see using EM? Ideally I would like to come up with the sql that EM uses to get the top SQL for a particular 24 hour period. Based on what I found, most of the information is in perfstat.stats$sql_summary. Has anyone done this before, and if so, could you share the sql script.?
Thanks,
Sunil.

Hello Alan,
Thank you very much for your answer. I implemented you solution as follows: I programmed a job exactly as you said and then I created a custom report which diplayed the 'output' column from mgmt$job_step_history. Unfortunately, although the 'output' column is CLOB and displays very nicely in any sql developing tool, when included in a report it seems that Information Publisher takes all the end-of-line out of it and thus it is displayed horribly, with no "enters"... Maybe if i used some pl/sql i would somehow manage to trick Information Publisher into displaying end-of-line characters...
In the end, i will use one of the two workarounds:
- program a job just like you said and set Grid control to notify me by email when succeded; this also includes the job's output, and so I can get the Top SQL reports via email. If more than one people would have to be notified by this, an email group would have to be set up by the email administrators in the company, and also a new user in grid control (a simple administrator with view privileges on the target, no super-user is necesary) with a notification rule that would send emails on succeed for the programmed job(s).
- send the output of the ADDM report per email from the target db - the grid control is no longer involved; the steps are:
select task_name tname from dba_advisor_tasks where created = (select max(created) from dba_advisor_tasks);
SELECT dbms_advisor.get_task_report('&addm_task_name', 'TEXT', 'TYPICAL') FROM dual;
Send the result by email. See Note 730746.1.
Thanks a lot,
Ana.

Top sql elasped time, how true is that

hi guys,
i am viewing an addm report and is concern about a top sql activity.
i have an sql having top elasped time.
<i>
2,372      2,275      128,690,535      0.00      4.28      fphtjnquzzpud      [email protected] (TNS V1-V3)      SELECT USER_ID FROM SUBSCRIBER...
</i>
q1) what is the meaning of elasped time ?
the time taken per execution of an sql statement ?
q2) is the elasped time in the report shown above = sum of all the the elapsed time per execution of the sql ?
if that the case, the most/frequently i run a SQL statement, the higher the elasped time it will be and thus higher db time.
but how can we say that it is an inefficient sql since it has the most elasped time just because it is run way too frequently then other sqls ?
Please advise
Regards,
Noob

How to Get TOP Sql

Hi All,
I need to get TOP sql query in 11g Database.
I dont know about PT.
User will carry on some testing activity on the Database, i need to get the top sql from the database.
There is no access to AWR, ADDM and Entriprise console.
I need to get the output of the queries by executing some sql.
Can some body help me in this regards.
Thanking You
Pramodh

>
Whether it is possible to get the full set of sql, i tried executing this it is gives the report part by part.
>
I am not sure what the problem is.
You get the top 5 SQL statements because of the "<6" part of the code. Would be top 10 if "<11" and so on.
Maybe you have got to format the output a little in SQL*Plus to get it better readable - I leave that up to you :-)
Kind regards

How to get top SQLs in a time period

HI, How can identify top SQL over a period of 1-month. Top SQL tab only displays top SQLs in last 24 hours in grid control.
Neeraj

AWR is your answer. Find the snapshots from Month old to current or what ever time you want and create a preserved snapshot set. and then create a report.
That will give you the top 10 sql with in that range.
AWR can be found under Adminstration tab.

Hi,
on 10g R2, in OEM (DB control) For Top SQL: Application I have :
Data for the chosen interval is not available.
Why ? Should I enable something or set a parameter ?
I have this setting :

Lock monitor, top sql and trace data viewer

can any one please tell me how can i access lock monitor, top sql and trace data viewer
i am also not sure whether these tools are installed on my machine or not, if they are please tell me how can i access them, if not please tell me how can i install them
thanks a lot

Hey,
You can launch OEM from a client machine and then:
- Log in as system for example;
- go to tools,
- then - Diagnostics Packs, then you will have:
a) Lock Monitor
b) Perfomance Manager
c) Performance Overview
d) Top Sessions
e) Top SQL.
I hope this can help you a little.

Top Sqls by Execution time

Hi,
Can you please provide a query which gives top 5 SQLs ordered by Execution time ( i.e Elapsed Time/No of Executions), for one day.
Appreciate your help.
Thanks
Sravan

Hi,
welcome to the forum!
Here is the query:
select sql_id, sum(elapsed_time_delta)/1e6 total_elapsed_seconds, sum(executions_delta) total_executions
from dba_hist_sqlstat st,
dba_hist_snapshot sn
where st.snap_id = sn.snap_id
and sn.begin_interval_time between sysdate-1 and sysdate
group by sql_id
order by 2 desc;Keep in mind that in order to use it you need the diagnostic pack license.
Best regards,
Nikolay

2 from v$sqlarea
3* order by CPU_TIME desc;
