Oracle report formatting takes long time

hi
i am using oracle 10g Application Server 9.0.4.0.0 on Red hat linux AS 3
oracle reports are run thru JSP's
some reports take long time to execute though query in it if executed on sql plus are fast.
it is fond that that formatting is going on for those reports
what might be the reason for this??
is the data fetched first and then formatting takes place as per data??
waiting for reply

Report execution takes long time

Dear all,
we have a report which takes long time to exceute due to select statement.. here is the code..
SELECT vkorg vtweg spart kunnr kunn2 AS division FROM knvp
    INTO CORRESPONDING FIELDS OF TABLE hier
    WHERE kunn2 IN s_kunnr
    AND   vkorg EQ '0001'
    AND   parvw EQ 'ZV'.
    l_parvw = 'WE'.
SORT hier.
* select all invoices within the specified invoice creation dates.
CHECK NOT hier[] IS INITIAL.
SELECT vbrk~vbeln vbrk~fkart vbrk~waerk vbrk~vkorg vbrk~vtweg vbrk~spart vbrk~knumv
         vbrk~konda vbrk~bzirk vbrk~pltyp vbrk~kunag vbrp~vbeln vbrp~aubel vbrp~posnr
         vbrp~fkimg vbrp~matnr vbrp~prctr vbpa~kunnr
         vbrp~pstyv vbrp~uepos
         vbrp~kvgr4 vbrp~ean11
    INTO CORRESPONDING FIELDS OF TABLE it_bill
    FROM vbrk INNER JOIN vbrp ON vbrp~vbeln = vbrk~vbeln
              INNER JOIN vbpa ON vbpa~vbeln = vbrk~vbeln
    FOR ALL entries IN hier
    WHERE (lt_syntax)
    AND   vbrk~vbeln IN s_vbeln
*    AND   vbrk~erdat IN r_period
    AND   vbrk~fkdat IN r_period
    AND   vbrk~rfbsk EQ 'C'
    AND   vbrk~vkorg EQ hier-vkorg
    AND   vbrk~vtweg EQ hier-vtweg
    AND   vbrk~spart EQ hier-spart.
Can anyone say about how to reduce the execution time.?

Hi
first of all never use move corressponding.
Rather you should declare a work area for table hier.
select values into the work area and then append that workarea into the table hier.
In case of for all entries include all the primary keys in the selection and for the keys which are of no use declare constants with initial valules like:
'prmkey' is a primary field for table 'tab1' .
Constants: field1 type tab1-prmkey value initial.
and then in your where condition write.
prmkey GE field1.
I hope it is clear to you now.
Thanks

MDX report rendering takes long time and showing Conflict Message

Hi All,
This is my MDX Query
with member
[Measures].[Rent] as
IIF(IsEmpty([Measures].[Budget]),
NULL, [Measures].[Rent])
select {[Measures].[Rent]}
on columns,
[Property].[Address].[All].children *
DESCENDANTS([Account].[Account Hierarchy].[Account Group].[Expenditures],
[Account].[Account Tree].[Account]) *
[Property].[Property].[All].children
on rows
from
[Master]
When i comment [Property] Dimension member , i am able to get the result, but i need Property Dimension in MDX.
Can anyone give some idea ?
Thanks in advance

Hi Jarugulalaks,
According to your description, it take long time to render the report when using [Property] dimension, right?
In this case, the issue can be caused by that there are too many members under this dimension. In your query, you used CrossJoin function to join multiple dimensions which might cause the performance issue. If you cross-join medium-sized or large-sized sets
(e.g., sets that contain more than 100 items each), you can end up with a result set that contains many thousands of items—enough to seriously impair performance. You can use the NonEmptyCrossjoin function instead of Corssjoin function. For the detail
information, please see:
http://sqlmag.com/data-access/cross-join-performance
http://msdn.microsoft.com/en-us/library/ms144797.aspx
Besides, the total time to generate a reporting server report can be divided into 3 elements: Time to retrieve the data (TimeDataRetrieval); Time to process the report (TimeProcessing); Time to render the report (TimeRendering). For the detail information,
please refer to the link below to see Charlie's reply.

Report Formatt takes long time -- Report Progress and background engine

We invoke reports from Forms using run_report_object.
A particular report takes a long time. As soon as we invoke the report, the "Reports Progress" window shows up. Right after that The "Reports background Engine" display as Formatting Page1, 2, 3 etc. It takes a long time to get this done for a three page report.
We are using Reports 6i. Any thoughts? Is this a query performance or Report format issue?
Thanks

Formatting page 1 often means that the query is still executing, not that the page is formatting page 1.
If the report is "Formating page 2" for a long while on a 3 page report (assuming page 2 is not another query in a different report section) it would seem that the query is passing bits of data back to the report a bit at a time.
In this case try adding the ALL_ROWS hint which forces Oracle to retrieve all rows (you optimizer may be set to first_rows)

Using Word Easy Table Under Report Generation takes long time to add data points to table and generate report

Hi All,
We used report generation tool kit to generate the report on word and with other API 's under it,we get good reports .
But when the data points are more (> 100 on all channels) it take a long time to write all data and create a table in the word and generate report.
Any sugegstions how to make this happen in some seconds .
Please assist.

Well, I just tried my suggestion. I simulated a 24-channel data producer (I actually generated 25 numbers -- the first number was the row number, followed by 24 random numbers) and generated 100 of these for a total of 2500 double-precision values. I then saved this table to Excel and closed the file. I then opened Word (all using RGT), wrote a single text line "Text with Excel", inserted the previously-created "Excel Object", and saved and closed Word.
First, it worked (sort of). The Table in Word started on a new page, and was in a very tiny font (possibly trying to fit 25 columns on a page? I didn't inspect it very carefully). This is probably "too much data" to really try to write the whole table, unless you format it for, say, 3 significant figures.
Now, timing. I ran this four times, two duplicate sets, one with Excel and Word in "normal" mode, one in "minimized". To my surprise, this didn't make a lot of difference (minimized was less than 10% faster). Here are the approximate times:
Generate the data -- about 1 millisecond.
Write the Excel Report -- about 1.5 seconds
Write the Word Report -- about 10.5 seconds
Seems to me this is way faster than trying to do this directly in Word.

I am unable login through sqlplus on my remote database server from clients . Where as i am able connect locally on the server.When connecting locally, the OCI client driver starts up the dedicated Oracle server process to service that session (which is why +$ORACLE_HOME+ needs to be set so that the driver can find the oracle executable and why +$ORACLE_SID+ needs to be set so that executable know which instance's SGA to attach to).
When connect via TCP, the Listener accepts the connection. If it is a dedicated server request, the Listener does this part - creates a dedicated Oracle server process.
It is this part that is failing according to the details you have supplied.
First off - a work around if this is an urgent problem that needs to be resolved (and potentially also the solution for your underlying problem) - configure Oracle Shared Server and have the OLTP clients connect to shared servers.
some times i am able to connect from clients(after 5 Mins). After that the session is working fine.This sounds like a problem with dedicated Oracle server process taking an extraordinary long time to start up. This will usually be an o/s related problem, as it is the kernel's task to allocate resources and memory, load that executable from disk, initialise it, etc.
The response of tnsping goes to 20000 msecs.This is something different - it means that the Listener is slow to accept() (a socket call) an incoming connection request. Likely this is caused by the Listener waiting on a dedicated server processes to start, or insufficient server resources to accept and process the incoming (tnsping) connection.
I have read some where that log files has reached 2GB. but in my case its not.I would expect to see some kind of server problem. Number of processes allowed per o/s user being exceeded. Lots of swapping between the swap disks and memory. Perhaps loads of connection attempts, packet drops and so on at IP stack level.

TNS-12560: TNS:protocol adapter error
TNS-00517: Lost contact
Linux Error: 32: Broken pipeThis means that the Listener attempted to start an Oracle server executable, but the the executable did not respond to the Listener (inter process communication likely needs to happen). Thus the Listener could not hand over the client connection to the server process.
There are a couple of reasons why this can fail.. most of them I would think are o/s and resource related. (assuming that your listener.log is configured correctly)
I suggest checking the server and ensuring that it is capable of handling the current processing and memory loads on it. Also double check your listener.ora file to ensure that the broken pipes (lost communication) is not caused by errant parameter settings.

Problem Export to Excel it takes long time and Takes more space.

Hello All,
when we export to Excel in portal(reports), it takes long time and it takes more space.
how to overcome this problem please any one knows provide the proper solution for this issues
Regards,
Ch.

Hi Chetans,
I have had the same problem, and I had to create a OSS message to SAP in order to solve this issue, until now I don't have an answer. They made me to change a lot of configuration in Java and BW without luck. To tell you more, when we try to export to excel the java instance restarts aumotatically.
But we have this problem, when we try to export a huge quantity of data, so I found a note which says the limitation of exporting to excel. Take a special attention to the Performance section.
Note 1178857
[https://service.sap.com/sap/support/notes/1178857|https://service.sap.com/sap/support/notes/1178857]
I recomend you that you create a message to SAP. If you find a solution, please let me know.

Payables Account Analysis report takes long time to produce xml output

Hi,
I am trying to get xml data for the Payables Account Analysis report. I have changed the output format of the concurrent program to XML.
The report takes long time to produce the xml data irrespective of the number of rows fetched. But the same report with Text output runs very fast.
Any reason why the xml output takes long time?
thanks in advance

Hi,
Thanks for the reply.
As mentioned above, i deleted the Q_FLEXDATA and ran the report. it takes less time.
But Will the report data not affected when we delete Q_FLEXDATA Group? and Why this flexdata group affects the running time?

Report takes long time to refresh

Hi Experts ,
I have an issue ,when I have only used one workshet to upload as the original workbook has about 25 worksheet tabs and is too large to upload.The report takes 20 minutes to refresh I was rebuilding the report when I noticed that when I added the formulas to the bottom to the original report the report started to take longer to run.When the bottom section of the report is not included the report refreshed in about 2 minutes.
In the file that completes faster,there are no formulas after line 353
In the file that takes long time o refresh,the start on line 357.When the bottom section of the report is not included the report refreshed in about 2 minutes.Any sugession.Thanku.
Regards
R@vi

hi,
If you discover significant high frontend time, check whether the formatting is the reason. If so, either switch it off or reduce the result lines.
As formatting information is not transferred, the time consumed in the frontend can be reduced.
But the workbook you are executing may obviously take much time.

Oracle9i reports take longer time while running in web

Hi,
I have developed few reports in Oracle9i and I am trying to run the reports in web. Running a report through report builder takes lesser time compare to running the same report in web using web.show_document. This also depends on the file size. If my report file size(.jsp file) is less than 100KB then it takes 1 minute to show the parameter form and another 1 minute to show the report output. If my file size is around 190KB then the system takes atleast 15 minutes to show the parameter form. Another 10 to 15 minutes to show the report output. I don't understand why the system takes long time to show the parameter form.
I have a similar problem while opening the file in reports builder also. If my file size is more than 150KB then it takes more than 15 minutes to open the file.
Could anyone please help me on this.
Thanks, Radha

This problem exists only with .jsp reports. I saved the reports in .rdf format and they run faster on web now. Opening a .jsp report takes longer time(file with 600KB takes atleast 2 hours) but the same report in .rdf format takes few seconds to get opened in reports builder.

It takes long time to load the parameter's value when running we run report

Hi,
It takes long time to load the parameter's value when running we run report. What could cause this? How to troubleshoot the behavior of the report? Could I use Profile and what events should i select?
Thanks

Hi jori5,
Based on my understanding, after changing the parameter, the report render very slow, right?
In Reporting Service, the total time to generate a report include TimeDataRetreval, TimeProcessing and TimeRendering. To analyze which section take much time, we can check the table Executionlog3 in the ReportServer database. For more information, please
refer to this article:
More tips to improve performance of SSRS reports.
In your scenario, since you mention the query spends less time, the delay might happens during report processing and report rendering section. So you should check Executionlog3 to check which section costs most of time, then you can refer to this article
to optimize your report:
Troubleshooting Reports: Report Performance.
If you have any question, please feel free to ask.
Best regards,
