Charts Slow Report Rendering To A Crawl

Aug 23, 2006

I've searched the forums on this issue, haven't really found the answer.

I have several nifty little sales reports which crunch a ton of data quite efficiently and render in just a few seconds in Report Manager. I've pushed as much of the data processing back to the server as possible, use a stored procedure (with parameters) in a shared datasource, don't return unneccessary data, all that. It works great.

When I first developed the reports, I continued generating my charts (which use the same data as the reports, just grouped differently) in Excel and pasting them in as images. Now I want to stop that nonsense and use the SSRS charts. I fooled around with the charting function and got a reasonable facimile of my Excel charts, two per report, which use their own separate stored procedures and the same shared datasource.

Now, reports that used to render in 5-8 seconds may take 1-5 MINUTES. Help! It's definitely the charts--taking them back out fixes the problem.

I have complete control over the datasources--would it make more sense to use non-shared sources, or to create totally separate shared sources? I saw a post that recommended "making data calls non-synchronous," but I have no idea how to do that.

Thanks for any suggestions.

ASP.NET Report Viewer, Slow Rendering, Image Broken

Jan 29, 2008

Hi,

I have been using the report viewer to render my reports on a webpage. All worked fine for a time and now nothing is working correctly.

I have about ~8 report viewer on one page, all in an individual IFRAME. What happen is, sometimes I'm getting an error from IE (Internet Explorer cannot display the webpage) or the report starts loading (I see the title) but where the chart should be I have an X (broken image) icon.

Sometimes when I click on the image and choose "Display Image" the image will display.

Facts


Reports loads correctly on the report manager site (the Reporting Services webpage)
Once those errors starts appearing, the session seems to act funny and I can't even refresh the webpage (F5)
I have the latest report viewer patch installed
I have the SP2 for SQL Server 2005 installed
Running Windows 2000 Server
Running IIS 6
The website was developped using IIS 5, but was tested on IIS 6 for about 3 weeks and we started to have problems today.
The reports are linked with Analysis Services to get the data from cubes.
I'm really out of ideas right now. Maybe I should just restart the IIS server, but the thing is live and I can't do it right now. However, if I need to restart it, will the problem occurs another time? Will it become a solution to restart the server?

I already restarted Reporting Services and nothing has changed.

Thanks

Either Rendering Tiff Images In SRS Report Viewer Or Converting Tiff To Jpg Or Gif And Then Rendering

Jun 19, 2007

First of all, this is not in reference to using SRS (SQL Reporting Services) to render a report and then use one of the extensions to render the complete report as a pdf, tiff, excel etc. We have an opportunity to render a list of claims and then embed the supporting docs for each of the claims within the report. We don't have an issue referencing jpg and gif images via URLs and then rendering them within the report after the grid information. We do have an issue rendering tiff images within the report.



You can insert an image object into SRS at design time and have it render and you can convert a complete report to a tiff image but I cannot find a way to be able to render a tiff image when running the report. All you get is the red "x".



My question is has anyone encountered the same issue and, if so, what did you do to resolve the issue?



Thank you,



J Z

Slow Performance When Rendering Pages In SQL Server 2005 Reporting Services

Jul 3, 2007

I have designed a fairly simple report in report designer that uses an analysis services cube as its input, and a basic matrix object as the primary design component. Cube performance either via object browser in Analysis Services or via connection from Excel is great. It does exactly what you build a cube for, i.e. it builds aggregations you can get to quickly. However rendering from a report designer report within Report Manager is a different story.



Even though this report is being rendered from an execution snapshot, it is painfully slow at opening and closing different levels of drill down. The report does have six levels of drill down, which I am sure is a factor. If I use a smaller dataset, performance does become more acceptable. However, I don't consider the requirements of my report to be all that extraordinary.



My conclusion thus far is that larger data sets with many possible page renderings are not the best candidates for HTML rendered reports. In this case Microsoft's cube analysis add-in to Excel might be a better choice. Thoughts and feedback on either how to improve the rendering speed or other presentation alternatives that would perform better would all be welcome.

SoapException While Rendering Report Through WebService - Error During Processing Of ‘ReportParameterTime’ Report Parameter

May 5, 2008

I am extracting RS reports through a WebService:
report = execService.Render("EXCEL", null, out extension, out mimeType, out encoding, out warnings, out streamIds);

Some works fine but some are generating the following SoapException:

Error during processing of €˜ReportParameterTime€™ report parameter. ---> Error during processing of €˜ReportParameterTime€™ report parameter. ---> Error during processing of €˜ReportParameterTime€™ report parameter.
I set required parameters to their default values. In this specific report I have two required parameters:
1: ReportParameterTime, String
2: ReportParameter1, String

I set them to their default values (ReportParameterTime to "[Czas].[Kalendarzowy].[Rok].&[2007]" - means
Time Calendar Year 2007) but I am getting the exception above. I set parameters using this code:

execService.SetExecutionParameters(parameterValues.ToArray(), CultureInfo.CurrentCulture.Name);

Where parameterValues is a List<ReportExecution2005.ParameterValue>.

When I am using Microsoft.Reporting.WinForms.ReportViewer the report is generated without
any problems. I can see one parameter to choose: "Kalendarzowy" (means adj. Calendar) and can
select years, the default value is "2007".

What am I doing wrong and how can I fix this error ? Does anybody know ?

Regards,
Daniel

SSRS Report Rendering Different In VS2005 And In Report Viewer Via URL Access

Apr 17, 2008

Hello,
I'm using Reporting Services to render a text (stored in sql as varchar(max)). The text is all plain text, with some lines having trailing spaces.

Source text file i've imported to SQL via SSIS:
CLIENT: 10055
STATEMENT 2007
DATE:1002993
THIS IS THE OTHER STATEMENT
COLUMN1 COLUMN2 COLUMN 3
TRY THIS


*Note the trailing spaces on the line before 'STATEMENT 2007'.

I've designed a report using the Report Project in VS2005 to retrieve this text via a stored procedure. When I test the report using the 'Preview' tab in the IDE, it looks good
CLIENT: 10055
STATEMENT 2007
DATE:1002993
THIS IS THE OTHER STATEMENT
COLUMN1 COLUMN2 COLUMN 3
TRY THIS



But when I deploy the report and run it using URL Access:

CLIENT: 10055
STATEMENT 2007
DATE:1002993

THIS IS THE OTHER STATEMENT

COLUMN1 COLUMN2 COLUMN 3
TRY THIS

On all lines with trailing spaces, they (the trailing spaces) have been removed. This is affecting my formatting of some reports and statements. We really want to use the report viewer as it has built in paging, print and export capabilities.

Why does it look okay in VS2005 but different in Report Viewer via URL Access and Report Manager?

Note: When I export as PDF, it looks okay.

The stored procedure I use to return the data is a CLR Hosted assembly as below:



Code Snippet
Partial Public Class StoredProcedures
<Microsoft.SqlServer.Server.SqlProcedure()> _

Public Shared Sub GetPagedDocument(ByVal inText As SqlString)
Dim dr As SqlDataReader
Dim row As New SqlDataRecord(New SqlMetaData("RowText", SqlDbType.Text))
Dim cmd As New SqlCommand("select cast(doc as varchar(max)) as 'DOCTEXT' from testdoc WHERE id='" + inText + "'")
Dim cn As New SqlConnection("context connection=true")
cn.Open()
cmd.Connection = cn
SqlContext.Pipe.SendResultsStart(row) 'initialise the resultset to be returned
dr = cmd.ExecuteReader
'If no records in result set, return.
If Not dr.HasRows Then

row.SetString(0, "There is no document to display or you do not have permission to view the document.")
SqlContext.Pipe.SendResultsRow(row)
SqlContext.Pipe.SendResultsEnd()
' SqlContext.Pipe.Send("There is no document to display.")
Return
End If
'Read rows in the result set
dr.Read()

'Get the entire text
Dim docText As String = dr.Item("DOCTEXT")
'debug
row.SetString(0, docText)
SqlContext.Pipe.SendResultsRow(row)
SqlContext.Pipe.SendResultsEnd()
Return
'end debug

End Sub
End Class




Any help will be appreciated.

Report Pagination For Charts

Feb 15, 2007

Hi,

We have developed few reports displaying data using chart layout. In the Data tab, we have specified MDX query that will return top 10 records.

But now, instead of restricting to just top 10 records, we would like to display all records and go in for pagination.

Is there some setting in the chart properties, where in I can display the first n records in first page, and the next n records( if available) in the next page and so on?

Can I specify the value of n somewhere in the propeties?

I read through many posts regarding pagination but those couldn't help me much.

Please help me in solving this problem.

Any help would be appreciated.

Thanks in advance!

Probelm With Report Charts

Sep 20, 2007



I have two data sets but from the same data source. I created two different tables from these two data sets. Now I want to include a chart too. But When I insert the chart, it gives a erorr message.

The dinfinition of the report/my report name is invalid.
More than one data set, data region or grouping in the report has the name'chart1_seriesgroup1'. data set, data region and grouping names must be unique within a report.


Does any body know why this happen?

Report Rendering (II)

Apr 30, 2007

Hi,



I have been using the following code, (thanks to Shyam), to display address fields. This works great when using preview in BIDS, but the address shows on one continious line when the report is redered in Reporting Services.





=First(Fields!Name.Value) & IIf(First(Fields!Address1.Value) <> "", Chr(10) & Chr(13) & First(Fields!Address1.Value), "") &
IIf(First(Fields!Address2.Value) <> "", Chr(10) & Chr(13) & First(Fields!Address2.Value), "") &
IIf(First(Fields!Address3.Value) <> "", Chr(10) & Chr(13) & First(Fields!Address3.Value), "") &
IIf(First(Fields!Town.Value) <> "", Chr(10) & Chr(13) & First(Fields!Town.Value), "") &
IIf(First(Fields!County.Value) <> "", Chr(10) & Chr(13) & First(Fields!County.Value), "") &
IIf(First(Fields!Post_Code.Value) <> "", Chr(10) & Chr(13) & First(Fields!Post_Code.Value),



Any one any ideas?

Report Not Rendering In Report Manager

Dec 19, 2007



Hi All,
I have a report which gets data for around 5 different parameters for 5 servers. It needs to render different graph for each parameter, each server. It renders it properly (after running long though, which can be understandable) on the Visual Studio Preview. But when deployed on the Report Manager, it does not produce the graphs. It runs for long time and ends up with this error:


The following error was encountered:
We can not connect to the server you have requested.



This means that:
The server might be busy at this time.

The server is not reachable.

Please try later to see if you can go through.

Though I have configured the report execution NOT to time out. As such, subscriptions also do not work, It says, "Failure sending mail: An error has occurred during report processing."


So, has anyone faced similar problem and fixed it? If yes, can you please share the same?

Thanks a lot.

Manoj.

Reporting Services :: Charts Not Visible In Report Manager

I am able to preview my report in Microsoft Visual Studio with a chart embedded at the top of the report. However after uploading the report to Report Manager, the chart is blank. How can I get the chart to be visible in Report Manager?  I am using SQL Server 2012 on a Windows Server 2012 R2 machine.  I can see the chart if I edit the report in Report Building in the print layout mode.  I can also see the chart in my Microsoft Visual Studio Project.

Report Rendering - Performance

As far as I know there are 2 ways to render the report in a Web page:
1. Using ReportViewer control and call its Render method
2. Using URL access

Which of the method is faster? As we are in the process of increasing the Performance of our Reporting Web Application.
I appreciate any suggestions in this regard.

Report Rendering/Exporting

Jan 10, 2008



My report is currently rendering about 50,000 rows and can still be increased.I am using SSRS 2005.I am exporting my rdls into HTML,Excel and PDF.My problem is when i export all the rows in PDF it won't continue and an error was produced.It says "Too many results, please constrain your parameters or try the other format."But using the same parameter which brings out the 50,000 rows,it works fine in HTML and Excel.

Which of the 3 rendering extension is the fastest in performance?Could it be HTML?What could be the reason why it wont work on PDF?Can't it contain such bulk record?Or is there anything can be done to solve the problem?
If anyone have encountered the same problem,we will be happy to hear from you.Any ideas and comments will be greatly appreciated..Thanks

HTML String Rendering In A Report

Jun 16, 2006

We have a "Comment" field that is saved as a HTML string to the DB. This field needs to be pulled into a report as rendered HTML.

I know this has been hashed out before, but has anybody found a good solution in the past couple of months?

We are thinking about storing two versions of the Comment in the DB: one with HTML, one as simple text. Has anybody found this an acceptable solution? I know it flies in the face of good DB design, but it seems the quickest, easiest solution...

Any word if this will be fixed in the next major release of SSRS? Can we expect this release any time soon?

Thanks for looking,

Horrible Report Rendering Performance

Feb 11, 2008



Hello! We are having a strange problem with Reporting Services 2005. Our RS server is located in a DMZ with the supporting RS database housed in our internal network. We have a batch of reports that perform well when rendering to browsers in our internal network. However, when accessing these same reports externally, the reports take a very long time to render. The difference between internal vs. external is huge; we are looking at maybe a minute tops to render the report from an internal browser vs. 10-15 minutes from an external client browser. The website and reports are setup for anonymous access, so it shouldnt be an authentication problem.

The RS execution log doesnt indicate much difference between the two. The data retrieval does take a little longer (only a second or two), according to the log, for an external request. But still, the times recorded in the Execution Log dont match at all what we are experiencing for external requests.

The various logs, both for reporting services and IIS arent picking up any anomalies either and Im at my wits end as to what else I can use to try and troubleshoot this problem. Has anyone seen this behavior before, or have any ideas what might shed some light on this?

Rendering A Report Using Custom Assembly

May 17, 2007

I have created a custom assembly and referenced it and the program builds successfully. When I try to run the report in design mode, it will not render, it throws an exception when it tries to create a PDF. When I remove the assembly, the reports work well. So I'm not sure what it is that I'm doing wrong - does anyone have any suggestions?



namespace Calculations

{

public class calcPercentage

{

public static decimal Percentage(decimal decValueOne, decimal decValueTwo)

{

decimal decPercentage = 0;

if (decValueOne == 0 || decValueTwo == 0)

{

decPercentage = 0;

}

else

{

decPercentage = (decValueOne - decValueTwo) / decValueOne;

}

return decPercentage;

}

}

}

Then in my textbox I put:

=Calculations.CalcPercentage.Percentage(SUM(Fields!PreviousYTDExpenseAmount.Value, "Template_OutputData_Sales"), SUM(Fields!PreviousYTDExpenseAmount.Value, "Template_OutputData_CGS"))



I referenced the assembly and added it to C:Program FilesMicrosoft Visual Studio 8Common7IDEPrivateAssemblies and I still get that error message so I do not know what the problem is.



The line where the exception occurs happens here:

byte[] bytes = MyReport.rvOutput.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);





Thanks so much for you help! If you have any suggestions about my next error...i'm all ears!

Sorting A Report After Rendering To Excel Or Pdf

Apr 2, 2008

Ok guys, here's the problem. Normally if I were sorting a report that needed to be rendered to pdf or excel, I'll sort the data in the dataset before loading it into the reportviewer in my code. This is in vb, for example:

dataSetName.Tables(0).DefaultView.Sort = "field ASC"

But for this particular case, I have to load the data into the report first, because in the actual report I have to combine two columns based on certain criteria (i do this using an expression for a column in my table) , and after those two columns are combined then they must be sorted.

But since the data is already loaded into the reportviewer I can't sort like I normally would, the report is rendered in either excel or pdf so interactive sort is pointless. I can't sort through table or properties or the properties of the text box because both fields are combined and you can only sort based on one field.

Any ideas?

Rendering PDF Report With URL, Force Requery Of Datasource

Oct 11, 2007

Greetings,

Let say I first use a URL in a web browser to render a PDF file.

Next the data changes.

Now I use the same browser session and call the URL again to render the PDF file; in the second rendering, the PDF report reflects the old data and not the changed data.

How do I force RS, using the same browser session, to render the second PDF file by requerying the data? Has any body come across the phenomenon? If I open a new browser session, the rendered PDF file reflects the new data. I have used Profiler to look at the SQL calls and sure enough, the second URL RS request does not requery the datasource.

Thanks
