Make files stored in Oracle db visible to Windows applications

Hi.
We have an application for storing images in an Oracle 10g interMedia. Now we want to make it possible for our users to access these images through normal Windows image processing tools (many different tools). Preferably it would work as if the user was browsing a network shared disk but the file information is retrieved and saved from/to the database without any "real disk" in between. We handle lots of images and they are quite big so its not an option to store them on a temporary disk. What we are looking for is something that could be described as a Virtual File System or a simpler version of such.
Does anybody know of a solution for this?
Thankyou!
/Henrik

While it's certainly possible that there are other tools to do this, I'd be a bit surprised if there were. I know Oracle invested hideous amounts of time getting IFS out the door, I would be surprised if there was enough demand for an IFS-like product to warrant a third party investing similar amounts of effort to develop an alternate implementation.

Reading an XML file stored in Oracle

Is it possible to read an xml file stored in Oracle via Oracle methods?

If by "read" you mean "read as text", then you can just select the document as a CLOB and return it.
If by "read" you mean "read and parse", then you can use the Oracle XML Parser for PL/SQL to parse the CLOB into a DOM structure.
My Building Oracle XML Applications book has lots of examples of doing this, but especially in chapter 5, "Processing XML with PL/SQL".

This file I have stored in Oracle as table of XML Type.
Now I have build a little Java Programm, that displays the XML File like the File structure in the Windows Explorer.
I want, when I choose a file in the File structure, that the ID3 Informations like album artist a.s.o. can be displayed. My problem is, I couldn't get these informations e.g. in an array from the database. Any suggestions how I could realize this in Java?
Thx for any comments
Max

Try this:
select extract(xmltypefieldname, '//xpath/field@attribute').getStringVal() from yourtable where yourwhereclause
You can also select elements that match certain attributes by using a predicate such as field[@attr = myval][@attr2 = myval2]...
Hope this helps.

Accesss Files Stored in Oracle Files from Forms

I am attempting to access the files that are stored in Oracle Files (oracle collaboration suite) from an Oracle Forms.
To be more specific I am would like to implement a solution to access Files from Custom Form in Oracle Application(11i).
Any suggestions/thoughts in this regard is very much appreciated.
Pavan

Hi we are on a project similar to this, basically you have two options:
a) Use Java-Importer to include the necessary classes to interact with IFS (e.g. rename, delete or get informations about documents).
b) Use a servlet to get files out-of and into IFS.
Because we had to do a lot of "loading" and we didn't want to run a round at client side to sign our forms jar files we decided to use method b).

Extracting Tiff files stored into Oracle 8.1.7 as Long Raw

I have around 1 million tiff images stored into Oracle 8.1.7. The field type is Long Raw. The frontend used to store images into the database is SQL Windows 5 from Gupta Corporation, now called Centura. I guess the images are stored in binary format in the database. I need to extract these images at the OS level. Each Rec_no contains one tiff file in database. The table structure is as follows:
Rec_no Number(8)
image Long Raw
My goal is to convert these tiff files to JPG files so that my web application written in ASP.Net can use them and show in IE. The files are required to be converted to jpg as IE does not have native support for showing the tiff files(I hope I am not wrong in this assumption). Can i convert these tiffs to jpg directly inside the oracle database??? or i need to extract them first, save at OS level, convert them and then write back to the database?? Pls give code examples if possible. I plan to migrate the database also from 8i to 10g shortly and this is one of the migration taks. Thanks in advance...

Oracle.Dataaccess.dll deploy windows application

I have a windows application that I developed in VS 2005 on XP. It access the DB via the oracle data provider. I just switched to vista and was adding some new items ot the application and then tried to redeploy it. I had to add a new installer to the project and whne i try to run the applciation on the client machine after it installs i get an unhandled exception. After remote debugging i get the following error. {"The type initializer for 'Oracle.DataAccess.Client.OracleConnection' threw an exception."}. I notice that the client on a previous install of the application uses 10.2.0.100 and the new client uses 2.102.2.20. Is this my problem?

The following steps can fix the """'OraOps10.dll': Access is denied.""" some times..
Solution Description:
Follow these steps to restore default access to Read and Execute access for Windows authenticated users:
1. Log on to Windows with administrator privileges.
2. Launch Windows Explorer from the Start Menu.
3. Navigate to the ORACLE_HOME directory and right click on the ORACLE_HOME folder icon.
4. Select the "Properties" option from the drop down list. A "Properties" window should appear.
5. Click on the "Security" tab on the "Properties" window.
6. Click on Autheticated Users in the "Name" list.
7. Uncheck the "Read and Execute" box in the "Permissions" list. This box will be under the "Allow" column.
8. Check the "Read and Execute" box. This is the box you just unchecked.
9. Click the "Apply" button.
10. Click the "OK" button.

Uploaded Files stored in Oracle 10G database or in Unix File system

Hey All,
I am trying to understand best practices on storing uploaded files. Should you store within the database itself (this is the current method we are using by leveraging BLOB storage) or use a BFILE locator to use the files system storage (we have our DB's on UNIX) . . .or is there another method I should be entertaining? I have read arguments on both sides of this question. I wanted to see what answers forum readers could provide!! I understand there are quite a few factors but the situation I am in is as follows:
1) Storing text and pdf documents.
2) File sizes range from a few Kb to up to 15MB in size
3) uploaded files can be deleted and updated / replaced quite frequently
Right now we have an Oracle stored procedure that is uploading the files binary data into a BLOB column on our table. We have no real "performance" problems with this method but are entertaining the idea of using the UNIX file system for storage instead of the database.
Thanks for the insight!!
Anthony Roeder

Anthony,
First word you must learn here in this forum is RESPECT.
If you require any further explanation, just say so.
BLOB compared with BFILE
Security:
BFILEs are inherently insecure, as insecure as your operating system (OS).
Features:
BFILEs are not writable from typical database APIs whereas BLOBs are.
One of the most important features is that BLOBs can participate in transactions and are recoverable. Not so for BFILEs.
Performance:
Roughly the same.
Upping the size of your buffer cache can make a BIG improvement in BLOB performance.
BLOBs can be configured to exist in Oracle's cache which should make repeated/multiple reads faster.
Piece wise/non-sequential access of a BLOB is known to be faster than a that of a BFILE.
Manageability:
Only the BFILE locator is stored in an Oracle BACKUP. One needs to do a separate backup to save the OS file that the BFILE locator points to. The BLOB data is backed up along with the rest of the database data.
Storage:
The amount of table space required to store file data in a BLOB will be larger than that of the file itself due to LOB index which is the reason for better BLOB performance for piece wise random access of the BLOB value.

We were able to do the same thing with Oracle Application Server and Oracle WebLogic Server. I cannot remember how different the processes were, but it seems like they were very similar. I am going to give you the instructions on how we implemented a "Read PDF" procedure on the WebLogic Server. If you are still on the Application Server you may have to do some Google searches, but it all boils down to the mod_plsql DAD Configuration file.
Our PDF was located in a table with the following structure:
CASE_DOCUMENTS
   (id_document                    NUMBER NOT NULL,
    doc_blob                       BLOB,
    note                           VARCHAR2(240),
    created_by                     VARCHAR2(20) NOT NULL,
    created_dt                     DATE NOT NULL,
    case_id                        NUMBER NOT NULL,
    filename                       VARCHAR2(100) NOT NULL)Based on that table structure we created a procedure named READ_PDF which you will reference below in the dads.conf file below:
CREATE or REPLACE procedure read_pdf (p_id_document IN number)
is
view_file     blob;
BEGIN
select doc_blob
    into view_file
    from case_documents
   where id_document = p_id_document;
OWA_UTIL.MIME_HEADER ('APPLICATION/PDF', FALSE);
HTP.P ('CONTENT-LENGTH: ' || DBMS_LOB.GETLENGTH (view_file));
OWA_UTIL.http_header_close;
WPG_DOCLOAD.download_file (view_file);
END;
GRANT EXECUTE ON read_pdf TO financial_user_role -- Name of role to execute
/Basically, you are passing in one parameter and that is the primary key for your table. You are selecting the pdf stored in a BLOB for that primary key. The commands below that allow the pdf to open up so you can view it – we got this off some search we did a few years ago.
Now, you need to add logic to your Oracle Form that will call the procedure above, but the URL is based on the dads.conf file that we will set up below… Anyway, we created a button on the form module with a label of "View". In the WHEN-BUTTON-PRESSED trigger the logic looks like this:
-- The View logic uses the DAD (Database Access Descriptors) method to view a .pdf file from the form.
-- The DAD was created on WebLogic Server with the name findadgen. This allows an http request be made
-- to the database.
declare
v_file          varchar2(400);
v_success       boolean;
ret_val         number;
v_http_link     varchar2(400);
begin
-- The format of the link is as follows: hostname:port/pls/DAD_name/procedure_name
v_http_link := 'http://finas03:8888/pls/findadgen/read_pdf?p_id_document=' || :case_documents.id_document;
web.show_document(v_http_link, '_BLANK');
end;The name of our WebLogic Server is "finas03" so that is what is listed in the URL. The "findadgen" is the name of the <Location> in the dads.conf file below, the "read_pdf" is the name of the procedure we created above, the "p_id_document=" is the IN parameter listed in the READ_PDF procedure created above, and the ":case_documents.id_document" is the reference to the primary key in our Oracle Form.
For WebLogic, you can either go through Enterprise Manager (directions below) or update the dads.conf file on the filesystem directly (if you update the dads.conf file directly then skip to step 4 and ignore step 5):
1.     Enterprise Manager -> Web Tier -> ohs1
2.     Oracle HTTP Server (pull-down) – Administration – Advance Configuration
3.     Select File – dads.conf
4.     Add something similar:
# ============================================================================
#                     mod_plsql DAD Configuration File
# ============================================================================
# 1. Please refer to dads.README for a description of this file
# ============================================================================
# Note: This file should typically be included in your plsql.conf file with
# the "include" directive.
# Hint: You can look at some sample DADs in the dads.README file
# ============================================================================
<Location /pls/findadgen>
    SetHandler pls_handler
    Order allow,deny
    Allow from All
    AllowOverride None
    PlsqlDatabaseUsername financial
    PlsqlDatabasePassword sdo_3#d1
    PlsqlDatabaseConnectString ffindbTNSFormat
    PlsqlNLSLanguage AMERICAN_AMERICA.WE8ISO8859P1
    PlsqlAuthenticationMode Basic
    PlsqlDefaultPage read_pdf
</Location>You are adding the <Location> section to your dads.conf file. The "finddadgen" is the name that you will reference in a change you fill make to your Oracle Form. The "financial" is the Schema, the "sdo_3#d1" is the password for that Schema, the "ffindb" is the database that the stored procedure is located on, and the "read_pdf" is a stored procedure you will have to create in order to read the pdf.
5.     Press the "Apply" Button
6.     Obfuscate the DAD password by running the dadTool.pl script located in $ORACLE_HOME/bin (This was done on Unix on our server with the following commands):
$> LD_LIBRARY_PATH=$ORACLE_HOME/lib;export LD_LIBRARY_PATH
$> cd $ORACLE_HOME/bin
$> perl dadTool.pl -f /u01/app/oracle/middleware/asinst_1/config/OHS/ohs1/mod_plsql/dads.conf
7.     Restart the Oracle HTTP Server using Fusion Middleware Control:
Enterprise Manager -> Web Tier -> ohs1
Oracle HTTP Server – Control – Shutdown
Oracle HTTP Server – Control – Start Up
If you followed the instructions above, you should have created a stored procedure, added logic to your Oracle form to reference that stored procedure, and created an entry in the dads.conf file. Once you move the form onto the server and you restart the HTTP Service, you should be able to view a pdf that is stored in a table directly from your Oracle Form.

Link multiple XML files stored in oracle database

Link multiple XML files
Can any one give some code example regarding my issue:
If I have for example file1.xml stored in one relational table and another file2.xml stored in another table ….etc
And I want to put link and reference which will make me able to link these files and make query or insert…etc
May be I need to use Xlink, Xpoiner or Xinclude . But if this is the solution to this problem please can you give a simple example that will help to understand the solution especially that I want to develop my project in oracle and I will register xml schema to insert the xml files in the database
Thanks lots and I am waiting for your solution

no answer for my question
is this thread is a write place or I have to move my query to another part of the forum
thanks

Reg. PDF file stored in oracle server directory

Dear All ,
How to stored PDF generated file in oracle server directory.
Thanks & Regards
shailesh

You need a directory object in Oracle for that server directory. That directory needs to be accessible (permission/ACL wise) to the local database processes to read/write from/
The schema that will be doing the read/write using that directory object, needs read/write privs on it.
UTL_FILE is used by PL/SQL code to write database contents to file.

How to make files stored in APEX available to non-APEX user?

Our application generates a number of files that are stored within apex_application_files.
Some of these are to be made available to a non-APEX application. We intended to do this through a granting access to a view to the non-APEX schema.
In order to access apex_application_files you need to set-up workspace security, etc. This can be done (details are in this forum), but relies on querying apex_applications - this view filters the applications using 'USER'. Therefore, it will only return applications where the parsing schema matches the user making the query.
So... how can we make some files available to the non-APEX schema?

If making serious use of file storage in the database then the best approach would be to store the files in application tables rather than relying on apex_application_files. This gives you total control over security, storage, associated metadata and so on.
