Heavy binary files must be stored in the database?

I was asked an interesting question: If a database contains all the data? Or large binary files must be stored in the file system?

Example of large binary files: videos or PDFs heavy (+ 200 MB).

With an old aspx web app (1.1) I tried to open a 200 MB pdf file stored as a BLOB in a base of Oracle 11 g and it has run out of memory.

However, same asp.net web application had no problem to open the same pdf file stored in the file system on a server. It could be that maybe there is some way to open fields heavy blobs with asp.net.

For reasons of integrity, I say that all data must be stored in the database, but my cases described showed me that maybe it's not the way.

SQL Server allows the content of the columns of varbinary (max) to be stored on the file system, maybe there is something similar in Oracle?

Depends entirely on how to open BLOB.
A simple way is enter any value in table (like getArray()). It can be risky when there are great values.
More sophisticated is to read in chunks.
In environments such as Java or ASP.net programming should be operable methods BLOB as a stream of data. In Java, it is ResultSet.getBinaryStream)
You can spend this additional flow, for example the browser connection. It will read the BLOB value into small pieces (or 64K) and pass it to the browser or whatever the customer.

  • View the file stored in the database in the customer's computer

    Hello

    I use oralce forms Release 10.2.0.1.0.

    In my application, files (.xls, .pdf, doc, gif etc.) will be stored in the database as BLOB table. I have to add the service to display the file in the client browser.

    I tried to use the webutil function to transfer the DB file to the client, then client to ACE and showed the file using web.show_document. The problem with this solution is file created guard as a server. is there a way I can programatically delete the AS file, after using web.show - posting document.

    Or did somebody suggest another solution for the same.

    Thanks in advance.

    Hello

    There is no need to transfer the file on the AS, if they are stored in the database.

  • Huge table with PDF (1.4 TB) be stored outside the database

    We have a table with BLOB where a PDF one stored. Now, we want to bring these data from the database (backup reaseans etc..).

    Any solution? Maybe a total another data store - stuff 'BIG DATA '?

    Thanks - regards

    Oliver

    If some give me a solution for a way to store PDF files outside the database.

    If you want to store the PDF file outside the database, then there are usually two approaches.

    (1) in the database, there is a table that stores the name of the file and the location on disk of the PDF. The written application the PDF file in the file system and then updates the database with the location and the name of this PDF file. If the application must Access the PDF, it looks up info in the database and then retrieve this file. The application must be able to read and write to the disk outside the database.

    (2) use such BFILE as mentioned previously.

    In both cases, your PDF documents is stored outside the database, but in my opinion, this does not eliminate the need for backups. If these PDF are lost, and there is no backup, then the data are lost. Because its outside of the database, a database backup backs up only data. The backup may be different and however different backup method is used. But I've seen cases where the db backup was performed at a given time and the binary backup was done at another time and restoration, there were inconsistencies that needed reconciliation.

  • Given Oracle Spatial are stored in the database tables?

    Given Oracle Spatial are stored in the database tables?

    Oracle spatial is DBMS oracle server functionality. It allows you in NATIVE mode, store and manage all standard types of spatial data and their attributes and metadata in the oracle database enterprise, in the way that you are quite familiar with. on top of standard oracle database features, adds types of geographic data, spatial index, geometric operators and queries, functions, spatial and analytical, to name a few.

    MapViewer is a feature of Oracle Fusion Middleware, which makes cards using spatial data managed by Oracle Spatial. That's what you called "generator of maps. but of course, it's not just a map generator, he has much more to offer, such as MapBuilder, WMS, Oracle cards.

    Hello

    try to do a procedure from your original like this code:

    procedure make_pdf(p_subscriber_no in number, p_subscriberdno in number)
    is
       l_blob blob;
       l_mime_type varchar2 (100);
       l_blob2 blob;
       l_mime_type2 varchar2 (100);
       mport varchar2(200);
       mrserver varchar2(20);
    begin
       warn('fsubdno'||p_subscriberdno);
       commit;
       mrserver := rserver();
       mport := 'http://'||mrserver||'/jasperreportsintegration/report';
       -- generate the report and return in blob
       xlib_jasperreports.set_report_url (mport);
       warn('firststrikeeee');
    
       xlib_jasperreports.get_report
          (p_rep_name => 'reinvx',
          p_rep_format => 'pdf',
          p_data_source => 'chess',
          p_rep_locale => 'de_de',
          p_rep_encoding => 'utf-8',
          p_additional_params => '&Psubscribe_no='||p_subscriber_no||'&Psubscribed_no='||p_subscriberdno,
          p_out_blob => l_blob,
          p_out_mime_type => l_mime_type
          );
       blob_loadb (mid(),p_subscriber_no,null,'renewal_invoice','renewalinv'||p_subscriber_no,l_mime_type,l_blob);
       -- release resources
       dbms_lob.freetemporary (l_blob);
    exception
       when others
       then
          xlog ('prc_get_report_tunnel', sqlerrm, 'error');
          raise;
    end;
    

    Then, you can call this procedure in a database job that you create with an apex as this process:

    begin
      dbms_scheduler.create_job (
        job_name        => 'make_pdf_job',
        job_type        => 'PLSQL_BLOCK',
        job_action      => 'begin make_pdf(' || :P103_SUBSCRIBER_NO || ',' || :P103_SUBSCRIBERDNO|| ') end;',
        start_date      => systimestamp,
        repeat_interval => null,
        end_date        => null,
        enabled         => true,
        comments        => 'Make pdf job from Apex page 103.');
    end;
    

    Kind regards

  • You want to read binary files in some parts of the 500th row in the 5 000th row.

    I have files of 200 MB of 1000561 lines binary data and 32 columns when I read the file and sequentially conspire full memory of the generated message.

    Now, I want to read the file in pieces as the 500th row 5,000th row with all the columns and it draw in the graph.

    I tried to develop logic using functions file advanced set file position and the binary file reading block, but still not get the sollution.

    Please, help me to solve this problem.

    Thanks in advance...

    Hi ospl,.

    To read a specific part of the binary, I suggest to set the file position where you want to read the data and specify how many blocks you must read binary file for reading binary file.VI

    for example, if you write table 2D binary file, and then mention you data type this 2D chart and make your account (5000-500). Then together, you produce position. If you have 32 DBL data type and column then it is 256 to the second row and 256 * 500 for line 501th. Use this number as input into your position.vi file get.

    I hope you find you way through this.
