Maximum file size that OSB can handle for JMS

Hi,
We have a requirement to process 60MB xml files over JMS in Oracle Service Bus. While prototyping this we are facing heap space errors.
Can somebody let me know what is the maximum file size that we can process? The scenario is as below.
JMS --> OSB --> JMS --> OSB --> JMS
Thanks

if you don't need to access the entire content of the message, you can try using content streaming
(see this OSB - Iterating over large XML files with content streaming discussion)
See also here http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/context.html#wp1110513 for best practices.
Otherwise I have noticed myself that OSB is very hungry in memory when loading large messages. I had trouble even with a 5 MB binary file being loaded - this would take 500 MB RAM. in these cases I would rather look for ETL tools such as Oracle Data Integrator or Open Source Pentaho.

    What is the file size that ODI can handle ?????????
    can it handle 1GB files without any issues?????????
    Thanks

    Hi Phani,
    It also depends on the type of file you are transfering. If have used the XML file around 1GB and the performance is very low. But we used the Database schema to load the XML data and the performance had increased very well.
    I never tried the large flat files load around 1GB.

    Please advice  me what shoud be the maximum file size that can be uploaded at one time.
    Thanks in advance.

    Hi,
    By default the maximum file size is 128 MB. You can configure that in visual administrator.
    http://help.sap.com/saphelp_nw04/helpdata/en/05/35e13d8ee48f5ee10000000a114084/frameset.htm
    If you as administrator need to upload a file with larger size, you can use km file repository like etc. and can upload file from OS.

  • Maximum File Size? How can I stop a "Send" in progress?

    What is the Maximum File size you can send?
    (Can't find it indicated anywhere on the Adobe site. Just says "large" files. I hope Adobe's definition of Large matches my needs.)
    Is there a way to stop the process of a "send" ?
    I am in the middle of sending a large zipped file to an email address (around 6GB, note: apparently JPEG's don't actually get smaller when you compress them) and it's taking a long time. I'd like to stop this and send a smaller zipped file first, but the "Cancel" button did not stop the process. Anyone know?
    Thank you

    Hi mariehill,
    [Mosaicriver, I believe I saw that your questions were answered by Bob on a separate thread; let me know if you need any further assistance.]
    At the moment, the Adobe Send team is working hard to improve the service's functionality with very large files. Mariehill, how large is the file you're trying to send? You may also want to check your upload speed, as that could affect the success of the sending process. If you continue to have trouble, we recommend trying the following:
    1. First, try uploading the file you'd like to share to your Acrobat.com file storage, and then sharing the file from there. Let me know if you need more detailed info on how to do that.
    2. If you've got a subscription to Adobe Send, you can also use the old SendNow service for the time being; the two products will coexist for a while longer until SendNow is retired later this year.
    We apologize for any inconvenience; we'll post to this forum when we have updates from the team about changes and improvements to the Adobe Send service. Let me know if there's anything else I can help you with!
    Best,
    Rebecca

  • Is there a maximum file size that can be converted to pdf

    I have a 448mb tiff that I want to convert to a pdf. However, Acrobat gives me the error that the file is damaged or there is some other problem. Photoshop CS5 opens the file with no problem. It won't convert it to a PDF either.
    The tiff is at 200 resolution. If I reduce it to 60 it will convert.
    Am I trying to do something that can't be done?

    Open in PS and print to the Adobe PDF printer. However, a 448MB TIFF seems huge. At 200 dpi and 24 bit color (millions of colors) that leaves you with a 61inX61in graphic. Even at 600dpi, that is 20X20.
    For us to help you, please indicate exactly how you are trying to convert from PhotoShop. For Acrobat, are you trying to open the TIFF in Acrobat directly? Is the TIFF a single sheet, or multiple sheet? There are a lot of unanswered questions for us.
    One of the limitations on file size is the size of the temporary PS file that is created in the PDF creation process. This PS file is created in the TEMP folder that is limited by MS. So you might try emptying the TEMP folder.

  • Is there a maximum file size (or number of hyperlinks) for iWeb?

    This isn't a problem, just a concern. I've built a very large iWeb file to keep track of a genealogy project and the file is getting big: there are 1800+ people listed in the file, each with her/his individual page; each page has a minimum of 6 hyperlinks (links to parents, children, indexes and home page); and the size of the iWeb domain file is approaching 600MB. It's a tiny file compared to Wikipedia, but I'm seeing the pinwheel "cursor of death" for c. 30 seconds whenever I launch iWeb and getting a bit nervous. Am I getting close to some sort of size/complexity limit for the iWeb program? Thanks in advance for any advice. (By the way, I don't plan to publish the genealogy on any sites; I always publish it to DVD-ROMs for family use only, so uploading is not a concern.)

    David ~ Probably. iWeb simply wasn't designed to do what you're doing with it. Although iWeb may not have a numerical limit on size or links, bear in mind that it was designed for small personal sites.
    One thing you could do to reduce the size is post some of your data on an external site such as Posterous and hyperlink to it. Posterous will automatically place PDFs in a convenient viewer, e.g.
    http://dont-panic.posterous.com
    By the way, the PDF there was converted from Posterous' web page via this:
    _Free online URL to PDF Converter_
    And Weebly allows sub-pages (and sub-sub-pages) accessible via drop-down menu. This might allow you to organize your data in a more structured way than iWeb allows:
    _Weebly Support Center: Sub-Pages_

  • What is the maximum file size for Pages?

    Hi,
    What is the maximum number of pages and maximum file size that I can have for Pages document?
    Thank you.

    chessmagnet,
    As a practicality in a large document it pays to break it up into sections in different documents with the numbering carrying on from the last one.
    Assemble the final document at the end when you need to create a T.O.C. and any hyperlinks.
    Several users have reported being unable to save very large files and other problems.
    It is a good safety measure anyway and as Yvan says it will work faster.

  • My service is converting from SendNow Plus to Adobe Send; what is th maximum file size?

    My service is being converted from Adobe SendNow Plus to Adobe Send.  There is very little detail on differences that I can expect between the two services.
    What is the maximum file size  that I can send?  Is there a maximum?
    Do I have a storage limit?  It was 2GB with SendNow.
    The files in SendNow have a time limit, but I cannot find anywhere this is defined in Send.
    Lastly, my subscription rate is higher than the rates quoted on the Adobe website, but I cannot find a way to correct this or make a change.

    Hi Raghuveer,
    Thanks for quick reply.  Sorry, I prefer not to share my designs so I cannot send you my sample of Ai file or screenshots.  I hope you understand. 
    Anyway, I have about 50 to 60 elements used 3D effects and 60 elements used brushes.   And about 20 some elements I defined as pattern swatches (about half of them used gradient). Also, added drop shadow, zigzag effect and accent edges on 5 elements.   And 3 layers filled with patterns (my artboard size is 1220 px W x 1500 px H).  I have my layers/artboard/ color & pattern swatches/ appearance panels opened up when working in Ai.
    I hope this gives you some idea how much I am doing and what I am doing with my Ai file.   And hope that you can advise if there should be problem if doing a lot in one file?  I just cannot stop designing sometimes.
    Added this- I have 18 artboards and 22 layers in my Ai file.  Photoshop doesn't have this problem  when working with a lot of layers, only Illustrator does.
    Thank you very much!!

  • What is the max file size that a Adapter Engine [J2SE] can handle ?

    We are having a scenario where a 4 GB compressed file needs to be sent across without mapping, I'm trying to explore the possible options to tackle this scenario.
    Some of the options, we are considering :
    - Sending a file from one Adapter Engine [J2SE] to another Adapter Engine [J2SE] bypassing PI. Adapter Logs will be monitored. What is the maximum file size that can be then handled assuming a standard installation ?
    - What is the max file size that Adapter Engine [J2SE] can send through PI without mapping?
    Any help with the above options or with any other possible solutions to handle extremely large file transfers will be much appreciated.

    Hi,
    j2se is not a good option here
    if you have 4gb then you need a copy solution
    a) build an proxy that will just copy the file from sender dest to receiver
    b) build an adapter that will do the same as proxy)
    this way processing of this message will be controlled with SAP PI/XI
    it will be as quick as copy & paste of the 4gb file
    I did the a) for one of the flow for 300 mb and it works perfectly

  • CLM - Maximum File Size for Contract Documents

    We did a search but did not find an answer for this.  For the CLM system does anybody know SAP's recommendation on the maximum file size that the application can reliably handle for contract documents?  We recently increased the maximum file size from 10MB to 50MB to accommodate a larger than allowed file size.  Now the business has requested the capacity to add files (pdf files) up to 115MB.  Would increasing our file limit to approximately 150MB be within the recommended parameters?

    There is no specific recommendation for maximum file sizes as this depends on how your time-out parameters are set, your server resources and network (also tunneling policies).  The fact is the higher the filesize the more risk you run in unreliable uploads.  Compressing files before uploading is a good practise for larger files.
    These are the same issues which you would run into if you for example upload to a sharepoint site or even a copy on a shared drive, it all depends on the same parameters. 
    Tunneling policies could also affect your performance as it will limit the upload speeds according the priority set on certain network activities and if it limits your bandwidth you run in the risk of time-out so as you see there is no straight answer to your question.  I know customers who can without no problem upload 150Mb files and others who already have issues with 50Mb.
    Unfortunate, as I do not know your architecture and infrastructure I can only advice to stresstest the conditions of 150 Mb uploades with several user ids and see if you get time-outs or if it degrades the network performance. One of the questions you should ask your business is how frequent are the occurences of 150Mb+ uploads and if it is the appropiate way.  It could be that these are very rare and in that case you could ask them to do this outside the busy hours of the network which will provides you less risk in problems.
