Large report

Hi,
What is the size limit to display the BI report on portal/web. If the the report is very large what is the best way to handel it. Should we use Information broadcasting or open hub. Please advise.
thanks,
Isac

check for query performance here:
OSS note 557870
you can restrict the dialog runtime with the parameter
rdisp/max_wprun_time
This will affect all dialog processes and is not user specific, so setting it to 5 minutes is probably not feasible.
The result set of a query can be restricted with the safety belt (see note 1127156), but again the setting is not user specific.
Another possibility is to restrict the memory per session (parameter ztta/roll_extension etc.), but again this is a global parameter.
As far as I know there is no way to have a resource limit for some users but not for others. Your best possibilty is to restrict the access to the 'dangerous' queries.
ztta/roll_extension and rdisp/max_wprun_time can be different on different servers, so it might be possible to set them to small values on one server and force the users on this server. This could be difficult if webreporting is used and it is also important that no other processes are running on this server as they might fail due to the restrictive settings.

Crystal Reports 10 Enterprise Server Issue - Exporting Large Reports to PDF

Weu2019re implementing a Crystal Reports 10 Server for a customer but weu2019re having an issue with exporting large reports to PDF. The report size that starts to show this issue is roughly 300 pages with 20 records per page. We use the default Crystal ActiveX viewer.
Basically what happens is that the user will launch the report in the ActiveX viewer and the large report will take a while to load, as much as 3 to 4 minutes. The user may then wish to export to PDF. Once they attempt it with these large reports the viewer will basically hang and possibly be processing but will then time-out after roughly 5 minutes with this error:
u201CProxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST /thinqreports/THINQCrystalInterface.asp.
Reason: Error reading from remote server
IBM_HTTP_Server/6.1.0.9 Apache/2.0.47 (Unix) Server at lmsproxy.aurora.org Port 443u201D
We believe this error is coming from a server on our network. We have a proxy server between users and the Crystal Server that has a 5 minute time-out for connections. What we want to know is:
- Is there a way to speed up this export to PDF process?
- Should the Crystal Viewer be keeping an http connection alive to the Crystal Report Server while its doing this export process?
- If not, what port does Crystal Viewer use to communicate with the Crystal Report Server?
- Is there something we can set in Crystal to keep an http connection open?
- What is actually occurring during this export process?
Occasionally, we may get the above error when simply launching a report, not just attempting to export to PDF. We presume that is because loading the report into the Crystal Viewer from the Crystal Report Server is taking longer than 5 min.
Anyone have any thoughts? Thanks.
Scott

Scott,
As this is happening within Enteprise (and I am assuming the report does not time out in the Crystal Reports Designer) I would suggest posting this to the BusinessObjects Enterprise Administration
forum.
My limited Enterprise knowledge would be to suggest scheduling the report as PDF but I don't know if that is a viable option for you.

Best approach for batch mode generation of large report via SSRS

I have revised this question now that I've determined that we *will* be using the Enterprise edition of SQL Server 2012.
I have a report (that I will deploy to an SSRS 2012 server) which can vary greatly in size. When the report is expected to be small (which we can determine ahead of time by means that are not relevant to this post), it will be rendered by a .NET 4.5 web
application using a ReportViewer control (in remote mode).
When the report will be large, we want the web app to "trigger" the report server to generate the report and deposit it as a PDF file or Excel file in a folder on a file share, and then send an e-mail notification to a configured user. Because
the reports can be very large, I would prefer not to stream them to the web app and from there to the file share. We have experienced browser timeouts in the past, and so I would prefer to have the SSRS server deposit the generated report directly to the file
share.
About 8 parameters have to be passed to the stored procedure which serves as the report’s data source.
The database where the stored procedure resides will soon be upgraded to SQL Server 2012.
I am fairly new to reporting services and wanted to ask what approach would be best suited for accomplishing the above-stated goals.
From what I've read so far, I know that one possible approach would be to use data-driven subscriptions but the question then becomes: after inserting report parameters into the subscription table, how does my web app trigger report generation?
Also, I want to deposit the report in a file share and send an e-mail notification to the user. Do I have to create two subscriptions? There is a configuration option when setting up e-mail notification to embed a hyperlink in the e-mail rather than actually
include the report in the message. If I select this option, do I give up the ability to specify the destination folder?

@JoeSchmoe115: Thanks for your suggestion. Using a web service or WCF service would still mean dealing with potential timeouts for very large reports (granted you can adjust those timeouts).
I think an approach using a console app could work, but rather than having the web app spawn it, an alternative would be to do the following: (1) have the web app insert report generation requests (including all necessary report parameters) into
a database table, and (2) have a console app, periodically invoked by Windows Task Scheduler, which reads that database table and then uses the SSRS API as you describe to generate the report, save the byte stream to a file, and finally send
the e-mail notification to the user.
mkedwards
What you've described will work but saving report generation requests in separate table may not be necessary. I don't have much experience with web services but can they just spawn C# console app with needed parameters and exit without waiting for console
app to complete?
The positive side of using database to store report generation requests is that you would have complete log of all requests. Your console app can then update database with completion status.

Apex+Cocoon PDF Printing issue on printing Large Reports

Hello All,
I m in a real hard situation with PDF printing in apex.. The application manages to push the report into PDF with lesser record reports but for Large reports, it says File corrupted when i open the downloaded PDF file..
I use Apex+Coocoon and fop printing. I found from some forums as this issue was with Java Heap size being lesser and asked me to increase the size.. so i increased the size from 128MB to 1024MB and my server settings allows me to set 1550MB at the maximum..
If i cross this limit the TOMCAT server stops from running...
But all of the above was not much fruitful, since it throws again the same errors if report rows crosses 6000+ rows, can any one help me out, do i need to check any other settings to make my large reports printable in PDF.
My application needs to print around *20000+ rows each report may have at least 20 columns* to get printed...
Much awaited for your assistance

Matt,
On this note, it probably also makes sense to mention that with APEX 3.1 we introduce a PL/SQL API that gives you much broader control over what is generated how and the method it's made available to the client. You'll get the ability to retrieve the PDF in a BLOB directly on the server, store in your own tables for later download or send via email attachment. You'll also get the ability to write your own download process using after-submit page processes. And you can have combinations of your own XML with your own stylesheets, or combine report queries with customer stylesheets at runtime, or just simply retrieve the results of pre-defined report queries / report layouts in BLOBs.
I'll talk about this much more on my Blog once 3.1 is out, and will provide whitepapers, how-to's etc

Marc

Large Report in XML Format issue

I am running an Oracle report with an output to XML but I am not getting all the the data. Is there a limit on how much data can be shown in an XML output? Is there a way to get large reports to show in XML Format? We are running Oracle ERS 12 on database 11g. Thank you

I wasn't getting an error at first but now I get the following error:
The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.
Not enough storage is available to complete this operation.
I don't have this issue with any other format.
I was wondering how much storage is needed?

Oracle 10g Discoverer Reports & export to xls fails for large reports

Hi ,
We have following configurations:
1: RHEL 5.4
2: Discoverer :Version 10.1.2.48.18
3: Oracle10g Apps Version : Version 10.1.2.0.2
Issue:
Most of small reports works fine ....but when large discoverer reports are executed the page
keeps on refreshing for 15-20 hours but no output ....same for export to xls ......
But same reports works fine in oracle9i for same data voulme....
Observations:
When on linux with top command the processes are monitored its observed that discoverer process
dis51ws dies for large reports after 1-2 minutes ...& the page keeps on refreshing but no output....
for 1-2 minutes it consumes 50-80% cpu utilisation then process disappears & cpu 80% idle ...
It seems that as 10g Apps is installed on RHEL 5.4 ...non certfified OS causing an issue...
Can any one adds more inputs in this regards......
we have checked logs : below are log details :
Below logs gives "Logkeys: exceptions discoiv.servlet_exceptions" for this report ...

Hi ,
as per Note: 466697.1 ....its an memory error....& need to increase MaxVirtualDiskMem and MaxVirtualHeapMem
But we already have slowly increased MaxVirtualDiskMem and MaxVirtualHeapMem to below very high values ...but the issue remains same.......
as per note we are getting Logkeys: exceptions discoiv.servlet_exceptions error but
after that we are not getting below error ............
Unexpected error in state machine: java.lang.OutOfMemoryError
Hence I presume that its different issue rather than memmory....
Below are pref.txt values..........
CacheFlushPercentage          = 25          # Percent of cache flushed if the cache is full. valid values 0 - 100%.
MaxVirtualDiskMem          = 9294967296     # Maximum amount of disk memory allowed for the data cache. Should be greater than or equal to MaxVirtualHeapMem
MaxVirtualHeapMem          = 4294967296     # Maximum amount of heap memory allowed for the data cache.
QueryBehavior = 0          # Action to take after opening a workbook (0 = Run Query Automatically, 1 = Don't Run Query, 2 = Ask for Confirmation)
Also we have raised an SR & as per SR .............all below settings are tried as per SR except for applying a recent patch....
====================================================================
Discoverer performance is largely determined by how well the database
has been designed and tuned for queries.
A well-designed database will perform significantly better than a poorly
designed database.
Workbook design can also affect query performance.
1. Apply latest Discoverer patch as documented in <<Note:237607.1>>
'ALERT: Required and Recommended Patch Levels For All Discoverer Version'.
2. Increase the maximum JVM heap memory:
In general, the default values for the minimum heap (-Xms) memory and
maximum heap (-Xmx) memory are sufficient.
However, if your organization consistently runs large Discoverer queries
then you may benefit from increasing the maximum heap memory from the
default values.
This is recomended if your users are typically running large queries via
Discoverer Viewer.
Increasing the JVM memory can help to avoid "java.lang.OutOfMemoryError"
in Discoverer Viewer:
Please see <<Note 563960.1>>, Best Practice: Configuring The
OC4J_BI_Forms JVM For
Discoverer Viewer/Portlet 10g Performance And Stability for specific
details.
3. Disable Query Prediction:
Query Prediction provides an estimate of the time required to retrieve
the information in a query.
The Query Prediction appears before the query and consumes time.
Edit the <oracle_home>/discoverer/util/pref.txt on the middle-tier
server and set:
QPPEnable=0
Also set:
QPPObtainCostMethod = 0
4. Uncheck the 'Enable fantrap detection' checkbox.
When the box is checked, every query generated by Discoverer is
interrogated. Discoverer will detect a fan trap and rewrite the query to
ensure that the aggregation is done at the correct level.
Please refer to <<Note:210553.1>>, Oracle BI Discoverer: Fan Trap
Resolution - Correct Results
Everytime for more information on fantraps.
To disable, in Plus go to Tools -> Options -> Advanced -> Fan Trap
settings.
In Viewer go to Preferences and uncheck the box.
5. Disable Materialized Views/Summaries
In pref.txt add parameter:
MaterializedViewRedirectionBehavior = 0
Value equal to 0 ensures that Materialized View (MV) Redirection is
always performed when MVs are available.
6. Improve query performance by optimizing the SQL.
In pref.txt modify/add following parameters:
SQLFlatten = 0
SQLItemTrim = 0
SQLJoinTrim = 0
UseOptimizerHints = 0
If value of SQLFlatten is 1 then Discoverer will merge inline views in
the query SQL where ever possible.
In case of SQLItemTrim, Discoverer will remove unused folder items from
the query SQL where possible and for SQLJoinTrim Discoverer will remove
unnecessary joins from the query where possible.
UseOptimizerHints will add Optimizer hints to SQL if set >
0.Unnecessarily making Discoverer perform these checks consumes
resources and rather than increasing the performance may reduce the same. So unless you feel these checks have to be performed depending on
requirements, assign zero to these parameters.
7. When Discoverer builds a query, Discoverer makes a database security
check to confirm that the user has access to the tables referenced in
the folders. Avoiding this check can save time.
So in pref.txt underDatabase section add:
ObjectsAlwaysAccessible = 1
8. Whenever you are creating conditions, ensure that you match the Case.
This in turn can reduce the time Discoverer spends on changing the Case
and matching.
For example:
option Upper(Department) in (Upper('VIDEO SALES')
9. Ensure that summaries are refreshed periodically in Discoverer
Administrator.
10. Increase the amount of memory available for the Discoverer data cache. Please refer to <<Note 245752.1>>, Explaining Oracle BI Discoverer
Session Memory Management
And Server Cache Settings.
11. Performance may be enhanced by enabling OracleAS Web Cache.

Error moving through large report

Post Author: dbronstein
CA Forum: General
We have an ASP.NET 2.0 app with Crystal XI R2. When we try to move to the end of a large report, we get this message:
Failed to retrieve data from the database. Details: [Database Vendor Code: 17 ] Error in File C:\WINDOWS\TEMP\annproc {72FCA892-D200-4116-9D3E-BA22AEE7DD45}.rpt: Failed to retrieve data from the database. Details: [Database Vendor Code: 17 ]
Small reports work fine. We get the same error when we try to export the report to excel. Does anyone have any ideas for a workaround?

I believe KBase [1200141 - How to set the focus of the .NET Windows CrystalReportViewer so the report preview scrolls without clicking|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_erq/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes.do]. Unfortunately as I type this, there is something wrong with the search and I keep getting 403 errors. Below is the contents of the kbase:
*Symptom *
In Crystal Reports XI and XI R2 the report page view for a .NET Windows application will not scroll up/down with the mouse wheel.
*Cause *
This is the default behavior of the CrystalReportViewer control for .NET Windows applications but can be changed with some custom code.
*Resolution *
In order to fix this problem you must set the focus of the Windows application to the main report tab in the CrystalReportViewer control.
This action must be done in the parent form's Activated event. Below is some sample code that demonstrates how this can be accomplished.
// This is a member variable which allows us to set the focus on the first time the parent form is activated.
// The form is activated quite often and we only want to focus change to happen once.
bool m_bFirstTimeActivated = true;
private void Form1_Activated(object sender, System.EventArgs e)
   if (m_bFirstTimeActivated)
   // The CrystalReportViewer control is made up of 5 controls. The control in the first position is the PageView
   // control and is the one that needs to be modified. The PageView contains a TabControl that allows us to
   // have the main report and all subreports displayed as other tabs.
   // We set the focus to the first tab in the collection so scrolling works automatically.
   System.Windows.Forms.TabControl oTabControl = (System.Windows.Forms.TabControl) crystalReportViewer1.Controls[0].Controls[0];
   oTabControl.TabPages[0].Focus();
   m_bFirstTimeActivated = false;

Trouble with large report

Software:
Oracle database 10.2.0.4.0 on Unix
Forms, reports, OAS 10.1.2.0.2 on my computer Windows XP SP3
Internet explorer 7.0
This is a conversion from 6i to 10g.
I have converted everything but am having problem with large report. It runs fine from report builder, runs fine from the command line, however, when called from a form, it looks like the report was running (about 100 pages) and then for some reason started over…data overlays data. Wish I could include a sample of the output...hard to describe.
If I restricted the report to the first 600 rows of data, it runs fine when called from a form.
Has anyone else had a problem like this? If so, how did you fix it?
Thanks in Advance for any help.
Puzzled

Have you manually created page 3?
What do you exactly want to do on page 3?
Do you want to see and update the data from the selected record in the single record view at the top of the page or
do you want to change the data in the tabular form at the bottom? Because in that case you need a "Multi Row Update" process. Just create a tabular from with the wizard and you can see which processes normally exist.

JRC degraded performance, large reports using exportPDF of JRC sample code

All,
I am using JRC, Weblogic, and Oracle in order to dynamically create reports using Crystal. The problem I am seeing is that for very large reports (e.g. 600K +), the performance degrades substantially.
There are not a lot of subreports, and I've narrowed it down that the queries are not taking significant amount of time to execute. I'm using the JRC Helper Sample code, exportPDF call in order to create these reports.
For small reports (e.g. < 40k) we are looking at a few seconds. When we start executing the larger reports we are seeing them in 6-20+ minute range.
Weblogic version is 8, jdk 1.4.
Any suggestions? We are not using stored procs, just straight JNDI/JDBC calls.
Thank you for your time,
Scott

Hi Scott,
I recommend to put this question in our [Java dev f|Java SDK Application Development;orum

Very large report

Post Author: ny3ranger
CA Forum: Crystal Reports
Can anyone tell me if the crystal report xi developer supports the generation of very large reports. Like a report that is 30 inches wide lets say.
What we are trying to to do is either
1. Generate very large report thta we print on a special printer.
or
2. Generate a smart report that will allow ups to use regular or legal paper to print. But then the printing must be done in a way that the row width should be equal to the entry in that row that has the most text. So for example
Page 1                                       Page 2                                             Page 3                                Page 4                                   Page 5
Row1 (3 lines)                             (5 lines)                                            (7 lines)                                (10 lines)                               (1 line)
Row2 (1 line)                               (1 line)                                             (1 line )                                 (1 line)                                  (3 lines)
So we need row 1 with fix width columns to be 10 lines long on all pages becase the same row in the other pages is 10 lines. And row 2 to be 3 lines because page 5 has that row with 3 lines.
This way we cna put the whole report together x pages side by side. Is this possible???

It should support large reports. Select that "Special Printer" and be sure the page is setup to 30 inches wide. CR should let you use that entire page.

High demand architecture, large reports, distributed printing, best practic

Hi,
I have a client with high demand for printing reports in different country regions and large reports (10000 pages some of them), today they are doing this with Oracle Reports, but the server regularly gets overloaded and some reports never complete. They use reports in PDF format.
Can you please suggest an appropriate architecture for this scenario. Or refer some documentation on Best Practices for high demand and distributed reporting?.
Case description
They have a centralized Reports Server and reports are used in different remote regions of the country.
Some reportrs have 6 pages and others may be more than 10.000 pages.
Reports server has communication with some remote facilities at 10 mbps, and some regional offices at 10mbps, but most offices connect at 512 o 1024 bps.
The idea would be having reports like "client reports" in the offices and request only "Data" to the server, so they can reduce network traffic, they believe most problems come from the fact that Reports Server sends heavy PDF thru the network causing lags and fails, some reports never complete, they have to resend them.
Some othes ideas also include : Reduce the business logic placed into reports, use of regional servers, or even they have thought in changing Reports for another tool.
Any comment or suggestion would be appreciated.
Thanks in advance for your attention.

i think better way is to keep business logic into database and generate ur reports using Forms(Oracle forms) based parameter forms and save results into temporary tables
show some progress bar status on ur forms so it will be easy for users how long they have to wait for report to generate
in reports there should not by anything more than select * from mytemptables

Performance: How to manage large reports with high data volume

Hi everybody,
we actually make some tests on our BO server system, to define limitations and oppertunities. Among other things we constructed a large report with a high data volume (about 250.000 data records).
When executing the query in SAP Query Designer it takes about 10 minutes to display it. In Crystal Reports we rebult the row and column structure of the query. The data retrieval in Crystal Reports Designer last about 9 minutes - even faster as in the query.
Unfortunately in BO InfoView the report is not displayed. After 30 minutes of loading time we get a timeout error RCIRAS0244.
com.crystaldecisions.sdk.occa.managedreports.ras.internal.ManagedRASException:
Cannot open report document. ---
The request timed out because there has been no reply from the server for 600.000 milliseconds.
Also a refresh of an report with saved data is not possible.
Now we are asking us some questions:
1. Where can we set the timeout for InfoView to a value larger than 30 minutes?
2. Why is InfoView so slow compared to Crystal Designer? Where is the bottleneck?
3. Whats the impact of SAP single sign-on compared to Enterprise logon on the performance?
Thanks for any helps and comments!
Sebastian

Hi Ingo,
thank you for your reply.
I will check the servers and maybe change the time limits.
Unfortunately we have a quite slow server system that probably cause this timeout. In CR Designer we have no problems, its really quick. Is it to expect that CR Designer and InfoView have almost the same performance?
Another nice point: When we execute the query in SAP BEx Query Designer it takes about 10 minutes to open it, in Crystal Designer it needs just about 5-6 minutes. We integrated exactly the same fields in the report, which exist in die SAP BEx query.
What may cause the difference?
- Exceptions and conditions in the query?
- Free characteristics in the query?
- anything else?
Best regards,
Sebastian

Large Report Errors out with Java Heap Space in EBS 12.0.6

2)As XML Publisher Administrator navigate to Administration->Configuration.
Under Temporary Directory pick a temporary file location on your concurrent processing node. This should be at least 5GB or 20x larger than largest XML data file you generate
Under FO Processing, set:
Use XML Publisher's XSLT processor set to True
Enable scalable feature of XSLT processor set to False (see #4 below),
Enable XSLT runtime optimization set to True
3)We also have tried to to apply the workaround mentioned in the document 747750.1
In to Concurrent -> Program -> Define, in the 'Executable' group, there is a field named 'Options'.
Enter the value '-ms1024m -mx1024m' as the value for this field.
None of these seem to have worked.
Also refered to the the previous forum entries on these. But did not find anything specific to EBS. Most of them were related to Standalone installations.
CAn anyone help me.

CPU reach 100% when saving a large report in pdf format

We have some reports that are fairly large. When we schedule them to save in pdf format, the job server takes all the CPU resources, and makes other servers slow. Is there a way to limit how much CPU the job server can take?

Just give
destype=mail desformat=pdf desname=emailid
in cmd line
Which reports version are you using ?
In 9i you have to specify outgoing mail server in
$OH\report\conf\server_name.conf
in this xml element (uncomment it)
<pluginParam name="mailServer">%MAILSERVER_NAME%</pluginParam>
