AJAX, how to check execution time of queries?

CF8, using CFDIV to bind to a CFC. The CFC has several SQL
queries, including select, insert, update, delete. I need to check
the execution time of these queries. I have the CF Ajax logger
turned on (cfdebug), but it doesn't seem to list query execution
times. I see the query execution times from normal form pages in
the log info on that page, at the bottom as normal, but not the
queries in Ajax binded CFC's.
Am I missing a server setting? I have everything checked in
the Ajax logger. Global, LogReader, http, bind, debug, info,error,
window.
Thanks in advance for any help!
Mike

I use Ajax (in CF7) a lot to access a SQL Server database. To
determine execution times for Ajax queries, I run the application
in Firefox with the "Firebug" add-on. Firebug reports the execution
of each (and every) Ajax transaction in milliseconds.

How to extract execution time of a step

how to extract execution time of a step ?
This step calls another sequence, and
I want to know how long it take to execute that seqeuence.
I need this information during run time, not in the
report.
thanks.

Hi,
You could try.
Enable the Record Result for the step in question.
This will allow you to extract the TotalTime.
Then you could use the RemoveElements(Locals.ResultList,"[0]",1) - this assumes you have only logged one result. This is the same as not recording results for that step.
Otherwise you will have to workout the time yourself by calling the API Execution.SecondsExecuting() - API Execution.SecondsAtStart().

I think you are using for all entries statement in almost all select statements but i didnt see any condtion before you are using for all entries statement.
If you are using for all entries in gt_opbal ... make sure that gt_opbal has some records other wise it will try to read all records from the data base tables.
Try to check before using for all entries in the select statement like
if gt_opbal is not initial.
select adfda adfadf afdadf into table
for all entries in gt_opbal.
else.
select abdf afad into table
from abcd
where a = 1
    and b = 2.
endif.
i didnt see anything wrong in your report but this is major time consuming when you dont have records in the table which you are using for all entries.

How to calculate Execution Time

Hi gurus,
Can any one tell me how to calculate the Report Execution time in Seconds.
We have one requirement.My manager told me track all the reports in Development server how much time those take to execute. and Compare those with Production server.
I dont have an Idea how to calculate the Execution time in Seconds.
Please guide me on this.
Thanks in Advance
Thanks and Regards
Siri...

hi
check se30
enter the prog name and press execute.
after your execution is over press back
then press evaluate in the initial screen.
you have the analysis
in that you will get the time in microseconds and you can convert to sec

Feature request: Add current execution time to queries

When you run a query in Toad you are notified about how long a query has been currently running for. However in SQL Developer you just get the bar moving back and forth until it completes and only then you get the execution time. It would be nice to have realtime notification about query execution time.

in 4EA2, I do see 'All Rows Fetched: 60 in 0.198 seconds' above the column headers in the results grid. Is that what you were looking for?

How to get execution time for a view inside procedure ?

Hi,
I want execution time for all the views in my database. I tried "execute immediate" but it does not seem to work.
It is not waiting to complete the execution of view to go to next step.
If I am executing the same statement in sqlplus, it is displaying correct time.
Here is my code:
Begin
output_file := UTL_FILE.FOpen ('RECORDING',v_FileName, 'W', 32767);
Open viewcur;
Loop
Fetch viewcur into v_view_name;
     Exit when viewcur%notfound;
     SELECT to_char(systimestamp,'DD-MON-YYYY HH24:MI:SS.FF') into v_start_time from dual;
     v_stmt := 'Select * from ' ||v_view_name ;
     Execute Immediate v_stmt;
SELECT to_char(systimestamp,'DD-MON-YYYY HH24:MI:SS.FF') into v_end_time from dual;
v_record_str := v_start_time||','||v_view_name||','||v_end_time;
     UTL_FILE.PUT_LINE(output_file, v_record_str);
End Loop;
Close viewcur;
utl_file.fClose(output_file);
End ;

How to check the time taking to extract rows from source and time load data into destination

Hi,
Recently I have started working on Optimizing an SSIS package in 2012. The package reads data from AS 400 server and load into SQL Server table.. No transformations are being used in the package. only ADO.Net Source and OLE DB Destination are using in the
package.
The SSIS package is extracting 6500 rows and loading into database per batch. This process is taking 18 seconds. I would like to know out of 18 secs how much time is being used only to extract data from the source and how much time is taking to write the
data to the database per each batch.
Any thoughts be greatly appreciated...
Thanks,
Venu.

Hello
We need more information regarding your system. If you are using SQL 2014 then you can use the new DMV
sys.dm_exec_query_profiles which is doing this exactly. Check out this URL: http://msdn.microsoft.com/en-us/library/dn223301.aspx
While executing your SSIS project you can examine each and every process and get the percentage it already did and all the information regarding it.

How to set execution time of the step with business days in the workflow

As we know, we can set how many days later the step should be execuated after previous step. now, the problem is how to set the business days (days except sunday and sataurday) for it. any one has good solution on it.

Hi Nick,
In order to find the Next working day you need to check for the Factory calendar days for eg, if a workitem has invoked today and if the Approver doesn't release the workitme for which u want to send a mail/reminder to the approver after say next 5or 6 working days, you need to create a function module.
For eg: In case of Purchase order, if the approver doesn't release the PO .
Create a Method saying "Next working day" , in which you will be passing the import parameters : PO, Factory calendar day and the sy-datum
and export parameter : date.
Create Input date and No of days as container elements of the Task and in the method create a Function module
In case of PO, consider the Factory calendar key from the T001W by joining the table EKPO there by passing the PO.
then pass the date, No of days(say 5 days) and the Factory calendar key to the "WDKAL_DATE_ADD_FKDAYS" , you will get the next working day of the employee.
Don't forget to check the Binding properly.
Do implement this logic and check the same.
Regards
Sharief

How to improve response time of queries?

Although it looks that that this question relates to Reports but actually the problem is related to SQL.
I have a Catalogue type report which retrieves data and prints. That is not much calculations involved.
It uses six tables.
The data model is such that I have a separate query for each table and then all
these tables are liked thru link tool.
Each table contains 3000 to 9000 rows but one table contains 35000 rows.
The problem is that the report is taking too much time - about 3-1/2 hours while
expectation is that it should take 20 to 40 minutes max.
What can I do to reduce the time it takes to produce report.
I mean should I modify data model to make a single query with equi-join?
A)Specially I want to know what is traffic between client and server when
1) we have multiple quieries and LINK tool is used
2) Single query and equi-join is used
B)Which activity is taking most of time ?
1) Retrieving data from server to client
2) Sorting according to groups (at client) and formating data and saving in file
Pl. guide.
Every body is requested to contribute as per his/her experience and knowledge.
M Tariq

Generally speaking, your server is faster than your PC (if it is not, then you have bigger problems than a slow query), let the server do as much of the work as possible, particularly things like sorting, and grouping. Any calculations that can be pushed off onto the server (e.g. aggregate functions, cola + colb etc.) should be.
A single query will always be faster than multiple queries. Let the server do the linking.
The more rows you return from the server to your PC, the more bytes the network and your PC have to deal with. Network traffic is "expensive", so get the result set as small as possible on the server before sending it back over the network. PC's generally have little RAM and slow disks compared to servers. Large datasets cause swapping on the PC, this is really expensive.
Unless you are running on a terribly underpowered server, I think even 30 - 40 minutes would be slow for the situation you describe.

How to reduce execution time of this SQL?

This SQL will output only 2 rows. I tried using hints (an index) but to no avail.

Or, is it NOT possible, limit of query optimization has reached?

How can i create time charateristic queries in BEx

I don't know how iam allowed to create a time characteristic query in BEx
Iam also looking for a solution to change query settings during the runtime

hey thanks for the answer
i changed the query design into an other order and now it looks better. But i still have a problem.
I just want to select a intervall from a year.
For instance its may 2007 now so i want to show all values for may 2007 to may 2008
But i am only allowed to filtering for each info object so my filters for the year are
2007, 2008 and for month may, juni, july......may
The result is i get all values for 2007 and 2008 i need a refrence from month for each year.

How to check logout time

Hello,
I am developing a site using JSP, in which I have to store login and logout time in database. I have noted the logout time when the client is properly logged off. But, if client just closes the browser, how can I note the time?
Please guide me.
Regards

Hi,
You need to define a class, say Timeout,which implements javax.servlet.http.HttpSessionBindingListener. Create a Timeout object and add it to the user session. When the session is removed, Timeout.valueUnbound() will be called by the Servlet engine. You can implement valueUnbound() to do the required operation.The logout time that was getting recorded depended on the timemout set on the server.
Refer servlet API : http://java.sun.com/products/servlet/2.2/javadoc/index.html
Hope this helps.
Thanks,
