best regards
Abdul Qadir

If you have the metalink access, you can check out the list of bugs reported under "Report Server Hangs". We found those to be very useful in helping us figure out the reports hanging which we encountered a lot of during our initial conversion from reports 6i to 10g.
Would be helpful if you could gather as much information as you can on the error to help figure it out.
- Oracle App Server version ?
- Any REP-xxxxx or ORA-xxxxx messages reported in enterprise manager (drill down to the job and report engine)?
- A particular report only or random ?

  • Crystal Reports hanging in Enterprise

    Just suddenly we are facing issues with some of the crystal reports . they were working fine in Business objects up to yesterday but today they are hanging , even when we try to open/modify parameter they hang. we are using Crystal report 2008 and BO R3.1.
    evnthough some reports hangs the others just run fine.
    we noticed that , the reports which are stopped working are the ones that have  " Printer Option" unchecked in Crystal Report designer . when we open these reports in designer and check that option on pagesetup and  save them back in enterprise they are working.
    I have no luck to find the rootcause of this issue. what have changed that caused this issue.
    It is happening on both test and production environments. I read somewhere on forum that it might be  related to printer driver, but we haven't updated any driver and nothing seems to be changed.
    any ideas?

    In the page setup put the option Microsoft XPS Document Writer in the Printer option before publishing it to BO Server .

  • Crystal Reports Hangs on .Load event

    Hi ,
    We are using CR 2011 on Windows environment (2008 R2) and  run the following workflow.
    1. We have created a rpt with 9 sub reports.
    2. We would like to print the port to a particular printer and hence have set the flag <NO Printer> on the report
    3. The application is a windows based application and not a web based application.
    4. We have tested the report by launching the report and printing it on the desired printer.
    5. We have a windows service that executes the code of reading the report and printing it out as a pdf / printer.
    6. Step 4 is an event based activity that occurs as frequently as every 2 minutes.
    7. The database is Oracle 11g
    PROBLEM:
    1. Generally all runs well, however once / twice a day the report hangs.
    2. We have created a dump file and observed that the hang occurs on .LOAD event.
    3. We are using the .LOAD with a single parameter that of the report name.
    4. We also observed that the spooler service hangs
    5. We are disposing the report immediately after printing it.
    After the problem occurs we are forced to start the windows service and the printer spooler service.
    Solutions tried so far:
    1. Changing the No Printer flag did not give any results.
    2. We have created a job that restarts the windows service and the spooler service after a period of 30 mins. - This has minimized the occurances but not eliminated the problem.
    Pseudo code:
    ReportDocument CR = new ReportDocument()
    CR.Load(<report file name);
    //Set Main data Source
    CR.Database.Tables[0].SetDataSource(ADODB.Recordset)
    //set sub reports
    CR.Subreports[<Index>].Database.Tables[0].SetDataSource(data table)
    //here it prints on default printer or the set printer. (Printer s are UNC printers, however we register them - they are visible as local printers on the given machine -  locally before printing)
    CR.PrintToPrinter(noOfCopies, false, fromPage, toPage);
    CR.Close()
    CR.Dispose()
    IF required we can also provide the rpt file and any other details.
    Our customers are really suffering cause of this and any help would be really appreciated.
    Thanks
    Anil

    Hi Ludek,
    In continuation, please find the stack for the hang.
    As we can see there is a OutOfMemory exception followed by a Stack Overflow exception and then we have the CrstalReports function calls.

  • Crystal Viewer report hangs

    Hello,
    I am having a problem deploying a Crystal report to run under IIS/aspx using the CrystalReportViewer.
    I rdp to the windows 2008 server, start crystal reports and the report works under Crystal on the server fine.
    Running the same crystal report on the same server using IIS/aspx and the viewer has a problem. I load the aspx page, the viewer shows a prompt with server name, database name, user name and password information. The details are all right, I enter the password and I just get the message 'Please wait while the document is being processed' that just stays there indefinitely. Everything is on the same server except the SQL Server and database. Crystal Reports and ODBC reach SQL Server fine and Crystal shows the report from the server, but the viewer just hangs.
    I have done this on two other customer servers and the above worked fine - the crystal report showed in the viewer. There is something different on this server that I cannot figure out.
    I stripped down the report to a single table and a few fields u2013 no multiple tables, joins, sub-reports, created a very simple report to try and isolate the problem. I also removed all the VB code behind u2013 pretty well just load the report and display.
    I loaded the CRRuntime_32bit_13_0_2 on the server, created an IIS application, copied over the report and aspx/code behind and tested.
    the web config has the Version=13.0.2000.0 assemblies.
    Any help resolving this issue would be appreciated. I have looked at 100s of google posts, most very similar, but none have helped get this report going.
    Thanks Nick

    Hello,
    I took a step back to basics.
    I copied one of the sample projects and made the changes needed to get it working properly.
    crsdk_net_samples_12_0_\Reduced_Code_Tutorials\ReducedCode_DBLogon\CS_Web_ReducedCode_DBLogon\CS_Web_ReducedCode_DBLogon.
    The report appeared properly in the browser now - no hanging after entering login inforamtion.
    I tested with the client 10 and native SQL Server drivers and both worked fine.
    I thought great problem solved, but when went back to version using some code behind same problem. I checked the aspx and made it identical to the one that works. So the aspx, IIS app, Crystal report, everything else is identical. The only difference is the cod behind.
    **** Using this works
    <Report FileName="C:\inetpub\wwwroot\CrystalReports\Transcript_ReportV3.rpt">
    **** replace with codebehind creates hang
            Response.Write("Report Path = " & Server.MapPath("Transcript_ReportV3.rpt") & "</BR>")
            Test1.Load(Server.MapPath("Transcript_ReportV3.rpt"))
            With CrystalReportViewer
                .ReportSource = Test1
            End With
    The full code used is below.
    Getting closer but still not there yet.
    Any other ideas appreciated.
    Thanks Nick

  • XL Reporter hangs during activation

    Hope somebody could provide solution to our problem.  First of all we are running SB1 2005 version, we performed backup monthly or yearly and version of XL Report  PL 25. We encounter this problem (XL Reporter hang) recently when we restore a previous database from a backup to another server in order for us to review reports made under XL Reporter.  We click the start button to activate XL Report, we waited for it to activate but it  never did.  So we end the XL Reporter process and retry again but the same problem encountered.  We even waited for it for several hours to no avail.  It did not even suggest error message.
    We appreciate for the support you could provide us.
    Thanks

    When you say when we restore a previous database from a backup to another server, you have to make sure the other server has exact environment like your current server.  That would be extremely difficult to match.  However, without match the chance for your XLR to run smoothly would be slim.  May I know why you need to restore your db to another server?
    Thanks,
    Gordon

  • 9i Reports hangs

    We've successfully installed 9iAS Release 2 and Report 9i Server on Solaris 8. Then I called :
    http://migserver:7778/reports/rwservlet?report=test.rdf&server=rep_migserver&destype=cache&desformat=pdf&userid=user/pwd@mydb
    1. I'm able to see the result from
    http://migserver:7778/reports/rwservlet?
    2. I've disabled Single Sign-On
    3. When I call test.rdf, I dont get any mistakes, but report hangs.
    We figure out the problem is : Oracle 9iASR2 doesn't have a built-in
    that was in 9iASR1 - vncserver.Uur production environment is built on SunFire v880 servers (over $250k) that do not have any video adapters natively. They require a product like vncserver or exceed to
    redirect the DISPLAY into. Even if we use the exceed to start the reports server, if the exceed session closes, any reports return an Oracle-Toolkit error.
    We heard, Solaris 9 is supporting vncserver.
    Does anybody solved this problem ?
    Thank you for any help.

    Some suggestions
    1) It is certified only on XP professional (not home edition)
    2) If it is already so, then remove PC Anywhere related PATH elements from SYSTEM PATH and try
    Also restart machine and try.
    3) Turn on tracing in $OH/reports/conf/rwbuilder.conf - uncomment trace element
    Then try. Then see logs in $OH/reports/logs. That will give a clue

    I am using developer suite release 9.0.4.0.0 and to run reports i use web.showdocument i face a big problem
    1.The reports hangs (as if the request goes and never comes back)
    and to stop hanging we close the oc4j and reopen it and this is nonsenese
    we tried to fix the parameter engineResponseTimeOut in rwserverconf.dtd file
    to a time it works for some time and return back to the same problem
    any one can help

    Suggestion is to apply latest patch of 9ias (9024 or 9023 I think). Patch is available in metalink.
    Lot of bug fixes have gone there .
    (Best is to go for 10g which is even more stable, but apply patchset if that is not acceptable)

  • Windows developed report hangs on Unix Reports server ??

    Hi,
    We recently migrated from a Windows BI tier to HP-UX Itanium. The problem I have is that one particular report just hangs in the Unix reports server. The basics of the report are that it has repeating frames which displays three record blocks per page. I use a formatting trigger on a derived field to alternate the background colour of the frames.
    After making several modifications to the report I've discovered that the trigger to alternate the background colour is the issue. I can use the same field with a trigger to say conditionally display a field or hide another frame and that works ok. I can set the background of the frame to another colour and the report works fine.
    As soon as I use a formatting trigger to change the background it hangs.
    In terms of report development I'm stuck with only Windows as Report builder is not available for our platform so troubleshooting this is a tedious process.
    Has anyone seen anything like this before ????
    Cheers,
    Ron

    hello,
    oracle reports has always had this dependency. it needs the x environemtn for rendering of the output. so you need an active xsession for the reports server to point DISPLAY to.
    a possible work around is the use of a soft-terminal such as VNC or xvfb (see oracle9i application server release notes for details).

    Please help me onthis

    Hello,
    Try exporting in the 'fully formated grids and text'. It shouldl give you the 'member alias' used in the report.
    Looks like if you export in the 'querry ready grids and text' it will show the 'member name' as in database although the report may have used the 'member alias'.

  • Web printing crystal report hangs on report.PrintOptions.PrinterName

    Hello,
    I have a report web page that displays a crystal report.  I have added a modal popup to allow them to select their printers.  When I go to print the report is hangs on the line of rpt.PrintOptions.PrinterName = li.Text.  The printer names are added to the list box using a Java applet.
    Here is the Sub it is running.
        Public Sub PrintReports()
            rpt = CType(Session("rpt"), ReportDocument)
            For Each li As ListItem In Me.lbPrinters.Items
                If li.Selected AndAlso li.Text <> "" Then
                    rpt.PrintOptions.PrinterName = li.Text
                    rpt.PrintOptions.PrinterDuplex = CType(Me.cboDuplex.SelectedItem.Value, CrystalDecisions.Shared.PrinterDuplex)
                    rpt.PrintToPrinter(CInt(Me.txtNumOfCopies.Text), True, CInt(Me.txtPageStartRange.Text), CInt(Me.txtPageRangeEnd.Text))
                End If
            Next
            Me.mpePrint.Hide()
        End Sub
    Any help would be greatly appreciated.
    Thanks,
    Patrick

    Sounds like you're trying to implement server side printing in your app. Which is fine, except the CR ActiveX print is client side printing. Just in case you're interested, the way to enable activeX print is to go to the property of the CR viewer and find "PrintMode". It will more than likely be defaulted to PDF. Change that to ActiveX.
    Now, back to the issue. This may still be a matter of permissions - essentially what Adam was after. Probably the easiest way to determine that is to use the [Process Monitor|http://technet.microsoft.com/en-ca/sysinternals/bb896645.aspx] utility. Once you have the log, search it for "Access Denied" messages.

  • Blocking locks by user report hangs

    Please,
    "Blocking locks by user" report under "Database Administration Section" of "Data Dictionary Reports" is hanging
    every time we try to run it against any database.
    Please, confirm this issue in Oracle Sql Developer 4.0 EA since it was working perfectly in

    Also, allow us an estimate deadline for correction.

  • Crystal Report Hangs

    Hi,
    Crystal Reports Server 2008 and Crystal Reports Client are installed in two different servers.  Both the serveru2019s operating system is windows 2003 SP 2.  ASP.Net (c#) is used for launching the reports. When I tried to launch the reports it hangs. After some time I got the following message
    COMException (0x80041017): Request timed out because there has been no reply from the server in 600000 ms.  
    CrystalDecisions.ReportAppServer.ClientDoc.ISReportAppFactory.OpenDocument(Object DocID, Int32 Options) +0
       ASP.crystalserver_crystal_report_server_aspx.Page_Load() in d:\TECH\report\Crystal_Report_Server.aspx:53
       System.Web.Util.CalliHelper.ArglessFunctionCaller(IntPtr fp, Object o) +8
       System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) +8664819
       System.Web.UI.Control.OnLoad(EventArgs e) +99
       System.Web.UI.Control.LoadRecursive() +50
       System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +627
    I got this error when the following statement is executed
    InfoObject infoObject = infoObjects[1];
    ReportClientDocument reportClientDocument = new ReportClientDocumentClass();
    reportClientDocument = reportAppFactory.OpenDocument(infoObject.ID, 0);
    I tried to increase the request timed out (up to 30 minu2019s) in the registry settings but also this fails.  There is no firewall available in both the servers. 
    Can any one provide me the required settings to over come this issue. 
    Please Note : Previously I was not able to login to the CMS server from the client machine.  After providing the server details in the clientu2019s host entries then I am able to connect to the CMS now.

    This still sounds like a firewall issue specificly when dealing with the RAS server.  I would refer you to the [Configuring The Crystal Enterprise SDK to Work With Firewalls|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/0047e5f4-3140-2b10-1bae-de175e4c741c] document.
    The other way to test this is by running the application on the same machine as the enterprise server and see if it still gives that error.  If it does, that means the report is taking that long to run, if it doesn't, then there is some sort of network issue.

  • Crystal report hangs when calling oracle package

    hi i have a oracle package that calls a proceadure, if i test this package in PLSQL developer it compiles and i get sensible results
    this package has been designed using a ref type cursor to be called from crystal reports. it primary objective when the report is run, is to use File util to output data to an xml file.
    when i run this from crystal reports it locks crystal reports up, and dosent output a file.
    any ideas why crystal is hanging?

    Hi yes the package uses fileutil to output a file,
    the report user has permission over the file util output directory.
    I have previously used this method to generate rpt, and other output files in parelell.
    thanks

  • Oracle Report Hang with error on 11g.

    Dear Team,
    I have following setup:-
    We are using oracle database 11g R2
    Oracle Forms & reports : 11.1.2
    O.S : Windows 7 Professional
    When I log in to forms, I am able to log in successfully, after that when i run the report from forms 11g, i receive the below error in web logic server.
    <Alert> <Diagnostics> <BEA-320016> <Creating diagnostic image in d:\oracle\middleware\user_projects\domains\classicdomain\servers\adminserver\adr\diag\ofm\classicdomain\adminserver\incident\incdir_27 with a lockout minute period of 1>
    Reports were running fine till today, but only recently i made one change in rwserver.conf, i changed maxengine = 2 there.
    Secondly I setup xampp apache server and gave a path in windows folder to instantclient for successfully connecting with php.
    Please let me know is the error coming because of the 2 changes or either of the changes. Or else, please let me know any workaround to avoid this error.
    Thank you in advance.

    Thanks Roberto for your reply.
    Now Reports were running fine, I removed xampp apache server path from windows folder and put same path at the end of oracle configuration path separated by semicolon.
    whenever I made some changes in configuration file weblogic server hangs up and it doesn't allow to run report on web while in report builder it works fine.
    What is the reason behind it, is there any permenent solution to this problem.
