Discoverer Viewer printing PDF hangs

Hi all,
I have installed Oracle BI Discoverer 10.1.2.48.18. It works fine exept that it is not closing discoverer processes. As number of processes raises the amount of free memory lowers. When about 10% free memory on the server the Discoverer Viewer stops creating PDF printouts.
I open Disco session, open sheet it displays OK. I can export to csv, xls and other formats except PDF. I also can not print PDF. If I click on Page for Print I can set PDF printing options. Then click on Preview or Print and got the Printing PDF - Wait screen. It lasts and lasts...
Tried opmnctl restartproc ias-component=Discoverer, Discoverer processes disappears, still can not print PDF.
After coplete restart AS (opmnctl stopall, startall) the function recovers.
Seems to be tied with memory usage.
I can restart the AS say 1 a week, but rather use other way to keep the Discoverer printing.
Any suggestions, please.

Hi Jiri
Your CPU and memory looks ok for the Discoverer usage you have described. I'd watch BPEL though and make sure that isn't grabbing too much resource. If anything, memory would be the one to increase. As I mentioned in a previous posting, a 4:1 ratio for smaller boxes is recommended. Your ration is 2:1, although for only 5 users you should be fine.
I'm assuming you are using Discoverer in stand-alone mode? If not, and you have the infrastructure database on the same machine you are definitely underpowered.
Regarding the memory, the server is supposed to clear the sessions eventually. One way that you can definitely help is to tell your users NOT to close the browser or click the little X at the top right-hand corner of the screen. This may well close the session on the client end but the server is still holding the session for them.
Here is what I always do:
1. When changing from workbook to workbook I always click File | Close to get rid of the current workbook completely
2. When exiting Discoverer I always use File | Exit, after using File | Close.
I seem to get far fewer issues this way. It's therefore a training issue and is something that you can do right now. Hopefully this issue will be cleared in the future.
Best wishes

  • Unable to view/print pdf from Banks website.

    I am unable to view/print pdf files from banks website, a white blank screen appears.  I've uninstalled and reinstalled Adobe multiple times.  I'm running Windows Explorer 9 and Adobe Reader XI.  I am able to view/print these files from a different computer and save them to a flash drive.  I am then able to open the files on my computer directly from the flash drive.  I am thinking maybe I have a setting enabled/disabled somewhere??

    Thank you for your response.  Please be patient with my ignorance--I am not a power user.
    1)I do not know what you mean when you direct me to open the PDFs within Reader.  I typically do open PDFs that are already stored in my files on my computer, but I don't know how do vies/download pdfs that I need to view or download from the Web from within Reader.  Can you please tell me the steps involved?
    2)  Do you happen to know whether this is a new development with Chrome?  I have been using both Chrome and Adobe Reader seamlessly for several years with no issues.

  • Printing pdf hangs

    When I try to create a pdf by justing printing using the adobe printer driver, it hangs.

    Hello samc32782856,
    Please let me know what version of Acrobat are you using.
    What type of document are you trying to convert to PDF using Adobe PDF printer?
    Does this happen with some particular document or every file you try to convert to PDF?
    Please let me know more.

  • Preview won't view/print PDF's correctly.

    I have used InDesign to create some brochures, but when I export the files as a PDF and try to view it in Preview, the program screws up the artwork. If I use a gradient or a transparant gradient, Preview wants to make it one solid colored object with no gradient at all. When I change my export settings in InDesign, Preview decides to put boxes around all of my text boxes while giving me transparancy. If I try to save the file as a JPEG or a TIFF, preview wants to wash out my colors and leave everything looking dull.
    I have tried every setting I know of to resolve this, all to no avail. Are there any color settings/options in preview that will actually make the program display things properly?
    Thank you.

    Thank you Allan and Barney.
    Alas, though this did solve my question - it did not solve my problem.
    I begrudgingly set-up the Adobe Reader account and downloaded the App. 
    Between: Apple's iCloud, Google Drive, DropBox, Amazon Cloud, and now Adobe Cloud, management of storage and documents is getting "complex" to say the least.
    I was hoping to keep all these "collection-type PDF's" with all my other "normal-type PDF's" on Apple's iCloud through Preview. 
    Oh well, another account opened and another: account, username, password, and Application to manage.
    Thank you both for your help and clarity on this issue.

  • Discoverer Viewer - printing problems..

    I have created a report where I want to "hide" the content of some columns. Some of the columns in the report are formated so that they have the font-color as the backgroud-color of the column - and therefore the content of the column does not show.
    When printing from Plus or Desktop the report looks fine - it does not show any numbers/text in the columns that have same font-color as the background color.
    The report looks fine in Viewer (on screen - even when shown in printer-friendly version), but when printing it - the formating seems to disapear... and the content of the columns are show on paper..
    Does anybody know how to keep the color-fomating when printing form Viewer?

    Hi
    As luck would have it I posted something on hiding columns tonight in another thread. It might help here too, so here goes:
    There are two ways that I know of, and there could be more, to hide a particular column in Viewer.
    The simplest is to move the column to the far right of the report and then tell Viewer to only display n-1 columns, where n = the number of columns in the report. To do this, follow this workflow:
    1. Click the Layout link
    2. Use the Move option to move the column(s) you don't want to display to the right of the last item that you do want to display
    3. Count the number of columns that you want to display
    4. Click the Rows and Columns link
    5. In Columns type in the number of columns that you want to display
    6. Click the Go button
    This second method works for tables and crosstabs that don't use Page Items. Use this workflow:
    1. Click the Layout link
    2. Click the More link
    3. For the column(s) you want to hide, click the Up arrow alongside each one and move it to Page Items
    4. Uncheck the box called Show Page Items
    5. Click the Go button
    I hope this helps
    Regards

  • Discoverer Viewer 10.1.2.55.26 PDF Printing Issue

    Hope someone can help with this as i am at a bit of a dead end as i have trawled google looking for the same issue but no one seems to report this.
    Using Discoverer Viewer i generate my report and then click the Printable Page link, then click the Printable PDF button, the PDF appears to get generated but when i click on the PDF doc then Adobe reader displays the message "The File is damaged and could not be repaired. Loca\EWHg7{w#h5d" When i go onto the app server and browse to the "$ORACLE_HOME\j2ee\OC4J_BI_Forms\applications\discoverer\discoverer\WEB-INF\export_output" i can see the generated PDF file but it shows as a 4kb file and if i try to open it i get the same message about it being damaged.
    I have another machine that does produce the file correctly, but it is the only machine that does so. It is still a win 7 machine using IE9 the only difference being that i have logged onto the machine as a different user. I though this may somehow be a user issue ? but why would my domain authentication account have any impact on the PDF process in disco viewer? not using single sign on, i am logging into discoverer viewer as the same user each time.
    Any help or ideas would be greately appreciated as this is very frustraiting.
    Thanks in advance
    Eddie

    Michael,
    Our server guy confirms that Version 6 Update 24 is what we have on the servers. He has been trying to solve this issue for two months with no real success. I just logged into Discoverer and did not see the errors. It's not every time a user logs in, but it's often enough to be quite a bit of trouble.
    Another issue that I see before me (literally on my screen) is when the dialogue box is up to open an existing workbook and the little blue text boxes, sometimes called "hints", pops up with the name of the workbook and it's owner, if the mouse pointer is not moved right away then that little blue box stays on the screen in that spot and does not move or erase. It will stay there until you exit Discoverer and exit from all Internet Explorer windows. When I minimize all windows, the blue text box is still in that spot on the screen now on my windows background.
    This blue box error has bugged some of my users but at least a user can move the screen around it. The other error is more serious because it keeps a user from getting their reports.
    Thanks for your help,
    Mike

  • Print report parameter and column headers PDF format from Discoverer Viewer

    Hi,
    From Discoverer Viewer 4i I'm presently using the printer friendly version to print my workbooks. I would like to know if their is a way to include report parameters and print column headers on every page.
    I would appreciate any pointers or workarounds to this issue at the earliest.
    Thanks
    T

    Hi T
    I don't think this is possible with 4i.
    Have you considered upgrading to 10g R2?

  • Discoverer Plus - Problem with Page Orientation when printing pdf's

    Hi,
    When printing pdf's in Disco Plus I have a problem:
    My workbooks are a mixture of landscape and portrait pages.
    I am printing the entire workbook and then using cutepdf to produce a pdf.
    If I print to paper I get the correct landscape/portrait settings.
    If I print to pdf then landscape pages appear vertically when I view on screen so that the text is running from bottom to top of the page.
    So it is picking up th portrait/landscape settings from the individual worksheets but cutepdf has not realised that the pages are landscape so they appear on the screen vertically.
    This was not a problem on discoverer desktop so I am confident that this is not a problem with cutepdf.
    Any thoughts?
    Justin

    Thanks 2257648922,
    Version details are as follows:
    OracleBI Discoverer 10g (10.1.2.3)
    Oracle Business Intelligence Discoverer Plus 10g (10.1.2.55.26)
    Discoverer Model - 10.1.2.55.26
    Discoverer Server - 10.1.2.55.26
    End User Layer - 5.1.1.0.0.0

    Oracle Database 10g Release 10.2.0.4.0 - Production

    So I assume that means my version doesn't have the bug you mention.
    Any other thoughts would be appreciated.

  • Adobe PDF viewer in MFC Hangs while using in Child Dialog

    Hi,
    I  am using Adobe PDF viewer ActiveX control in one of my application   made in MFC. The PDF viewer Loads PDF and Work well when i place it in  a  Parent Dialog. But, If i use it in Dialog that is embedded as a  Child  dialog to another dialog, it just hangs the entire application if  i try  to scroll up/down the viewer or click any print/zoom etc options  that  comes with Adobe PDF viewer.
    Could any  body help me on this, It already cost me a day to get a  solution.

    Thanks for the reply.
    I did forget to mention that I am now trying this under Windows 2000 Professional SP4 and VB6 SP5.
    Also I made a mistake in my previous post, I have Reader 7 on my pc, not 9.
    Adobe Acrobat Browser Control type Library 1.0 (AcroPDF.dll) can only be added to the project as a reference,
    not as a component. Project - Component does not list this. I tried selecting Project - Components - Browse.
    I then browsed to folder where I placed the AcroPDF.dll (C:\WINNT\system32). It was not listed in the default list since this lists
    only ocx files. I selected to show all files and the dll was then listed.
    If I selected this I received a message
    The file 'C:\WINNT\system32\AcroPDF.dll' was not registerable as an ActiveX component.
    Adding Adobe Acrobat Browser Control type Library 1.0 as a reference did not show anything in the toolbox.
    There was no red logo in the toolbox items.
    I definitely selected the General list and there was no sign of any Adobe or Acrobat item
    I then tried right click on toolbox, selected Components and Adobe Acrobat Browser Control type Library 1.0
    was not there.

  • Discoverer viewer -- export to pdf doesn't retain page settings.

    Hi,
    The report output in discoverer viewer is much different from that of plus. I am concerned abt the report headers. In discoverer plus, the headers are left, center and right aligned.
    But in viewer, every thing is aligned center. How can I get the report o/p (same as that of plus) in viewer??

  • How do I view/print a pdf document in an email? I'm not getting the little hand icon.

    How do I view/print a pdf document in an email? I'm not getting the little hand icon.

    Ah, yes, I'm using Adobe Reader!  That makes sense.  Thanks so much for your reply.  At the moment, I scan Word documents into my computer and they're automatically converted to PDFs.  If I had Adobe Acrobat on my computer, and scanned in documents, would they open in Reader automatically or could I open them in Acrobat and therefore add password protection?

  • Print pdf and view pdf

    hello
    i am created one pdf file from original pdf file and genereted pdf with data using itext library,but now my problem is how can view this file and print this pdf file using swing printing api

    but how to print?
    Note: Just because the PDF DocFlavor exists doesn't mean you can use it to print a PDF file. When you lookup the PrintService for the PDF flavor,it will report unsupported flavor. That means there is no print service for the flavor. Sun doesn't provide one for PDF files. To the best of my knowledge,nobody else makes one available either. Until such a time as someone does,you can't print PDF files using the new Print Service API.
    ??? is there another way to print a pdf-file directly from filesystem without using the command line like:
    C:\..\Acrobat 5.0\Reader>acrord32.exe/t test.pdf
    thanks for replys

  • Custom PDF Viewer & Printer

    Hi PDF Gurus,
    I need to develop an application in which I can:
    1- Only view a PDF document (and any other features to browse in PDF document) but not freely print it, save it as... and send it by email.
    2- with a customized button I can print document with some watermarks and text for every pages of PDF document.
    3- this application will open a document in an UNC path with access restrictions only for the application itself.
    4- The application will receive the following parameters:
    PDF file name to open, username and password to access to UNC path.
    5- Application will run on 50 client (up to 15 simultaneously) under Windows 32bit
    IS there someone that already developed it, or otherwise, could you please indicate to me a SDK Library for C++ or VB.net to develop it?
    Thanks in advance

    I'm looking for a virtual PDF-printer for PPC2003. I need to be able to print out from a database application for recording ECG on the PDA, and then print out the result from the recording to a file that can easily be sent by e-mail via GPRS from the PDA. I've searched everywhere for a virtual PDF-printer for the PPC2002 - 2005 witout success - does anyone know were such printer driver can be found, if there is any?
