Performance problem with Orcacle / Crystal reports 8.5 / ASP

Hi,
I have a performance problem with reports running crystal reports 8.5 with oracle databases.
Fetching data appears to be slow. Oracle trace reports (tkprof) shows that fetchsize=1.
Fetchsize in Oracle ODBC is 15 (default).
How can I update te fetchsize in crystal reports?
I would appreciate any help.

CR XI R2 is also still available for purchase. This is the last version of CR to use the RDC. Contact sales at 866-681-3435.
Make sure the installed versin is 11.5.12.1838 - if it is not, apply SP6:

  • Problem with the crystal reports XI

    Portuguese
    Boa Tarde, tenho um problema com o cristal reports XI.
    ele esta em producao fazendo a consulta em um servidor mas quando eu acesso passando parametro connectionInfo.ServerName = <endereco do servidor> para um servidor de teste pelo VStudio 2005, ele nao busca os dados deste e continua acessando o servidor de producao.
    gostaria de saber como consertar isso

    Good afternoon, I have a problem with the crystal reports XI. him this in production making the consultation in a servant but when I access passing parameter connectionInfo.ServerName =  I address of the servant > for a test servant for VStudio 2005, he doesn't look for the data of this and it continues accessing the production servant.

    Fabiano, here is what I understand of the issue:
    1) You are using CR XI (I am not sure if release 1 or release 2)
    2) you are using .NET 2005
    3) you are trying to change the server name, but the report keeps giving you data from the original server
    Please answer the following:
    1) Are you using CR XI release 1 or release 2?
    2) Can you change to the new server, using the Crystal Reports Designer?
    3) Can you duplicate the issue on your development computer?
    4) What Crystal Reports service pack are you on?
    5) Are you connecting to the database using OLE DB?

  • Default printer and problem with printing Crystal Report

    Good morning
    I have SAP B1 and on the client the default printer is "AMM_4014DN_PCL6_domain-srv FRONTE-RETRO"
    Then i have another printer "AMM_4014DN_PS_domain-srv".
    Before the default printer were the "AMM_4014DN_PS_domain-srv".
    Now the default printer is "AMM_4014DN_PCL6_domain-srv FRONTE-RETRO".
    When i push the button "Print" in the menu bar to print for example an invoice, instead of printing on the default printer AMM_4014DN_PCL6_domain-srv FRONTE-RETRO is always printing on then AMM_4014DN_PS_domain-srv.
    The report to print was made with Crystal Report 2008 and on the report I also set the correct default printer (AMM_4014DN_PCL6_domain-srv FRONTE-RETRO).
    So what's the problem ? Why is continue to print to the older printer ?
    So i also delete the older printer (AMM_4014DN_PS_domain-srv) and very strange still printing on the old printer.
    I also shut down the client, but no effect.
    The operating system of the client is Win Vista and SAP B1 is host on a Win2008 server.
    Thanks in advance.

  • CRVS2010 Beta - Problems with printing Crystal Reports for VS 2010

    Good afternoon,
    We have the following problem, we used the version of Crystal Reports that came integrated with visual studio for several years. But we are migrating to the version of Visual Studio 2010, and we are using the version of Crystal Reports for this same version, running on screen is correct, and run all the reports, but in print there is a failure we could not solve. Our customers use printers dot matrix as the "Epson LX300 +", but when you print the report leaves the impression defective in the previous version of Visual Studio 2005 "The impression is quite clear, we have attempted to overcome this problem with the options of PrintMode with activex and pdf in the CrystalReportViewer, and RenderingDPI option with multiple values. Obviously when using other types of printers such as laser or inkjet printing is perfect, but due to cost our customers use the printers mentioned. The server where the application is Windows server 2008 and client computers are windows xp, windows 7, windows vista. As network hardware and printers are working properly, and from other applications and from the other server with versions of Crystal Reports If anyone knows how to solve this problem I would like to receive support and ideas.
    Thanks

    I have a question about printing reports. We are using VS2008 and the CR reportviewer with printmode = ActiveX. Many of our users absolutely hate the number of steps they must go through and the time it takes to print a Crystal Report when printmode = PDF. In our environment several times per day, we need to produce hard copies of reports for legal reasons. Making the users first render the report, then had it off to Adobe to print simply takes too much time which is why we are using the ActiveX print control.
    We recently started looking at VS2010 and discovered the issue with the unbundling of Crystal Reports. We have not downloaded CR for VS2010 yet.
    My question is this: for VS2010, what happened to the ActiveX print control? I read somewhere that it was going to become some WPF-type thing but there weren't many details about that. So when a user clicks on the print button in the Crystal Report Viewer intended for VS2010, what can they expect? Can they still print straight to a printer (is there something that gives them this capabitliy like the Active X print control did?), or has that capability been deprecated and they have to go through PDF? Thanks in advance for any information you can give me.

  • Problem with starting Crystal Report document from SAP Gui

    Dear all,
    in Crystal Reports I created my first report (based on a BW query), which is executed successfully, when I run it directly from CR or from Infoview. The report is stored directly in BW and has been published successfulyl to BOE.
    If I try to run it native from the SAP Gui, the following steps happen:
    Internet Explorer is started with the following link:
    http://dtcmbbwp01.ctc.ch.rcc:1080/sap/bw/ce_url?(ce_protcl):(DS)(ce_server)/(ce_path_pr)/viewreport.csp(Q)bw_id=4I4B2HQG8KK2ICFPONVIG5D9Q&sap_sysid=(sysid)&sap_client=010&language=EN&sap-client=010
    this link is transcoded to the following:
    http://dtcmbbwp01.ctc.ch.rcc:1080/sap/bw/=ce_protcl)%3a//MONHAMBO020.world.mon:8080%2fSAP%2fviewreport.csp(Q&sap_sysid=BWP&sap_client=010&language=EN&sap-client=010&sap-language=EN&cmsname=MONHAMBO020.world.mon
    (I already entered /CRYSTAL/CL_BW_HTTP_HANDLER handler in the ce_url service)
    and afterwards I get an error 404 -> corresponding service not available
    which is obvious, as a service =ce_protcl is not existing at alkl.
    If I then execute my CR document again from SAPGui (without closing the IE), the standard BOE login page for the infoview is displayed, but I get an error:
    Account information not recognized: The credentials passed to secSAPR3 [] are invalid. Use the following format: sid~clnt/user
    I can logon with my BW credentials, and afterwards I can see my CR document.
    Any idea, what went wrong?
    Thanks,
    Andreas

    Dear Ingo,
    the basic installation of all BOE components was done by the SAP installation service and I checked several times your blog(s) and the corresponding parts on the BOE server and in BW. From my point of view we did all necessary configuration steps on BOE and BW (/CRYSTAL/RPTADMIN) which are necessary to setup the BOE software and the connections.
    I checked again the HTTP handler and it still says:  /CRYSTAL/CL_BW_HTTP_HANDLER
    I stopped and restarted the service, but with no effect at all -> I do not think that I need a restart of the server, right?
    My user is as well existing on the BOE server and I can logon to the BOE with my SAP credentials.
    I guess as well that the key to the success is the HTTP handler. The first link I provided is the link that is shown in IE, before I logged on to the BW server and I think this is correct, as the transcodification is done after(!) I logged on to the BW server.
    A part of the transcodification is as well working, as I can see the replacement of my ce_server, sysid, etc. But it seems to me that the first part of the string is crap:
    http://dtcmbbwp01.ctc.ch.rcc:1080/sap/bw/=ce_protcl)%3a
    Any further ideas?
    Thanks and best regards,
    Andreas

  • Problem with Exporting crystal report to Excel

    Hi !
    I am new to crystal world. I have an application which has csp code. From the csp code (internal website) we invoke crystal using viewer.cwr to view or export reports. Last week we upgraded from Crystal 10 to Crystal Reports XI Release 2. Due to this upgrade we did some modification to the Viewer.cwr url ( Changed to Viewer.asp too). Now the View option is working fine but when the report is exported to an Excel the columns are squeezed up.
    Here is the code for the viewer.asp :
    ExcelWindow = window.open("http://servername/crystalreportviewers115/viewrpt.asp?id=" + id + "&apstoken=" + escape(token) + <%Response.Write("'"&sReportLogin&"'")%>'&promptex-REPORTDATE='pRptDate'&promptex-State='pState'&promptex-usertype='pUserType'&promptex-startreport='pStartpSelect'&cmd=export&export_fmt=U2FXLS:3&',"ExcelWindow", windowprops);                                                         
    Is there any way to solve this formatting issue ? I tried changing the export format option as "export_fmt=U2FXLS:4" but this pulled up the data with the report header and sub heading in one row. Please help.

  • Performance problem with Filters of Crystal Report

    Hi,
    I have been facing this problem for a month now.
    Whenever I try to run a Crystal Report from Infoview it takes 5min or more to get the prompts screen
    but sometimes(mostly when i restart all servers) the filter screen appears real quick say 5 to 10 secs(is this quick?)
    I have no idea why this is happening! Is there an issue with the servers? or is this problem related to Crystal report?
    Please help. I tried googling for this problem but could not find anything that would help.
    Thanks
    Nilesh

    I am using a universe which uses a DSN to connect to the sql2k5 database. One thing I forgot to mention is that this is a clustered environment(with 2 servers) and the input/output file repository is set to a folder on a third server.
    Note: Even though the report filters take time to pop up, but the report runs very fast; doesnt take more than 5 seconds for a fairly complex report.
    Yesterday I did a trial install on a seperate server and the reports filters come up pretty fast.

  • Performance problem with CR SDK

    Hi,
    I'am currently on a customer site and I have the following problem :
    The client have a performance problem with a J2EE application wich call a Crystal report with th CR SDK. To reproduce the problem on the local machine (the CR server), I have developped a little jsp page wich used the Crystal SDK to open a Crystal report on the server (this report is based on a XML data source), setting the new data source (with a new xml data flow) and refresh the report in PDF format.
    The problem is that the 2 first sequences take about 5 seconde each (5 sec for the opening report and 5 seconds for the setting data source). Then the total process take about 15 seconds to open and refresh the document that is very long for a little document.
    The document is a 600Ko file, the xml source is a 80Ko file.
    My jsp page is directly deployed on the tomcat of the Crystal Report Server (CRXIR2 without Service Pack).
    The Filestore and the MySQL database are on the CR server.
    The server is a 4 quadripro (16 proc) with 16Go of RAM and is totally dedicated to Crystal Report. For the moment, there is no activity on the server (it is also used for the test).
    The mains jsp orders are the followings :
    IEnterpriseSession es = CrystalEnterprise.getSessionMgr().logon("administrator", "", "EDITBI:6400", "secEnterprise");
        IInfoStore infoStore = (IInfoStore) es.getService("", "InfoStore");
        IInfoObjects infoObjects = infoStore.query("SELECT * FROM CI_INFOOBJECTS WHERE SI_NAME='CPA_EV' AND SI_INSTANCE=0 ");
        IInfoObject report = (IInfoObject) infoObjects.get(0);
    IReportAppFactory reportAppFactory = (IReportAppFactory)es.getService("RASReportFactory");
    ReportClientDocument reportClientDoc = reportAppFactory.openDocument(report.getID(), 0, null);
    IXMLDataSet xmlDataSet = new XMLDataSet();
    xmlDataSet.setXMLData(new ByteArray(ligne_data_xml));
    xmlDataSet.setXMLSchema(new ByteArray(ligne_schema_xml));
    DatabaseController db = reportClientDoc.getDatabaseController();
    db.setDataSource(xmlDataSet, "", "");
    ByteArrayInputStream bt = (ByteArrayInputStream)reportClientDoc.getPrintOutputController().export(ReportExportFormat.PDF);
    My question is : does this method is the good one to do this ?
    Thank's in advance for your help

  • Problem on using Crystal Report Viewer on windows application ("specified type is not valid ")

    Hi
    I am having problem on using Crystal Report Viewer on one of my windows application.
    I am not sure how to put the Crystal Report Viewer 11 Control onto the tool box.
    I could found a Crystal Report Viewer control on my computer, but it is version 8.5.
    I have also found another one which is Called Crytal ActiveX Report Viewer, i don't think it is the one I can use. As when I try to load a dummy report on to the Crytal ActiveX Report Viewer, It return an error. "specified type is not valid"
    Please see the Code sample below.
    private sub loadReport()
         Dim r as New ReportDocument
         'v is the name of the Crystal ActiveX Report Viewer Control
         r.Load("C:\Report1.rtp")
         v.ReportSource(r) <---It throw error on this line.
    End Sub
    Could you give me some advice about what have I done wrong, How to check if I have set up the Crystal Report Component correctly in my Visual Studio 2005 Standard edition.
    Thanks in advances.
    Many thanks

    VS 2005 Standard and Express editions do not come with Crystal Reports; only the Professional and higher editions will have CR bundled. However, I believe you can purchase CR XI R2 Developer and it will give you the components you need to create a VS .NET 2005 application using the Standard edition.

  • Performance problem with Mavericks.

    Performance problem with Mavericks. My Mac is extremly slow after upgrading to Mavericks. What can i do to solve that?

    If you are still experiencing slow down issues, it maybe because of a few other reasons.
    Our experience with OS X upgrades, and Mavericks is no exception, is that users have installed a combination of third party software and/or hardware that is incompatible and/or is outdated that causes many negative performance issues when upgrading to a new OS X version.
    Your Mac's hard drive maybe getting full.
    Do you run any antivirus software on your Mac? Commercial Antivirus software can slow down and negatively impact the normal operation of OS X.
    Do you have apps like MacKeeper or any other maintenance apps like CleanMyMac 1 or 2, TuneUpMyMac or anything like these apps, installed on your Mac? These types of apps, while they appear to be helpful, can do too good a job of data "cleanup" causing the potential to do serious data corruption or data deletion and render a perfectly running OS completely dead and useless leaving you with a frozen, non-functional Mac.
    Your Mac may have way too many applications launching at startup/login.
    Your Mac may have old, non-updated or incompatible software installed.
    Your Mac could have incompatible or outdated web browser extensions, plugins or add-ons.
    Your Mac could have connected third party hardware that needs updated device drivers.
    It would help us to help you if we could have some more technical info about your iMac.

  • Performance problem with Integration with COGNOS and Bex

    Hi Gems
    I have a performance problem with some of my queries when integrating with the COGNOS
    My query is simple which gets the data for the date interval : "
    From Date: 20070101
    To date:20070829
    When executing the query in the Bex it takes 2mins but when it is executed in the COGNOS it takes almost 10mins and above..
    Any where can we debug the report how the data is sending to the cognos. Like debugging the OLEDB ..
    and how to increase the performance.. of the query in the Cognos ..

    Hi,
    Please check the following CA Unicenter config files on the SunMC server:
    - is the Event Adapter (ea-start) running ?, without these daemon no event forwarding is done the CA Unicenter nor discover from Ca unicenter is working.
    How to debug:
    - run ea-start in debug mode:
    # /opt/SUNWsymon/SunMC-TNG/sbin/ea-start -d9
    - check if the Event Adaptor is been setup,
    # /var/opt/SUNWsymon/SunMC-TNG/cfg_sunmctotng
    - check the CA log file
    # /var/opt/SUNWsymon/SunMC-TNG/SunMCToTngAdaptorMain.log
    After that is all fine check this side it explains how to discover an SunMC agent from CA Unicenter.

  • Problem with the crystal viewer

    Hi there,
    I have a problem with thw crystal viewer. I have reports developped in Crystal XI that run in vb.net within the "CrystalDecision.Windows.Forms.CrystalReportViewer" object. On all computer client everything works fin except on one of them. When the print button is pressed, it gave a "Object reference not set to an instance of an object" error. Since this error is raised by the "Crystal report windows form viewer" preview window i have no idea why this occured. We tried to uninstall the viewer and reinstall it without chance.
    The only thing i can tell is that this client use a "HP deskjet 3420 series" printer. that's the only difference there is on this computer. Anyone as an idea?
    Thanks
    Ben

    Hi Ben,
    Try moving that printer to another PC and install the print driver. If it fails there it's likely a driver issue. HP and Cr has a history of problems. Mostly it's HP drivers returning the wrong memory structure size.
    If you can find someone who is using Windows XP and Windows 2003 and see if either work. Or possibly plug the printer ina print server and see if that works.
    Next option is if you wrote the software you are running run it in debug mode and see if it captures anything when printing. If did not write it then ask the person who did to test it also.
    Next option if you want to dig deeper into the cause is go to Windows site and download a program called DebugDiag. Run this program and set it to capture crashes. It will generate a dump file which can be analyzed. It should tell you which API or function caused the crash.
    Thank you
    Don

  • Performance problems with jdk 1.5 on Linux plattform
