Writing a file to an Oracle Directory

Hello,
I'd like to use a database trigger or PL/SQL to write a text file to to a directory on my database server. Is that possible? I know I could write a daemon that runs on the OS, but I'd lie to run it from the database itself.

OK, figured it out. This was helpful: http://www.adp-gmbh.ch/ora/sql/create_directory.html

Copying a BLOB to a File in an Oracle Directory

Is there a straightforward way to copy a BLOB into a file in an Oracle Directory?
The BLOB contains a binary (pdf) file.
Thanks in advance

Assuming you're on 9i or later, you can loop over the BLOB and use the UTL_FILE.PUT_RAW method to write out 32k chunks of the PDF at a time.

Processing OS Files in an Oracle Directory

I have an application that gets XML files and stores them in a directory. I'd like to write a PL/SQL program that I can schedule to process all files in the directory. I won't know at run time what the file names are, so I need a way to somehow loop through all files in the directory, do my processing, and exit when I've run out of files.
I've been reviewing documentation and it doesn't look like fileGetName or fileExists will work for this type of processing, since they either assume a known file name or return the directory name, which I'll need to specify since there are multiple directories used by this process.
In pseudo-code, here's what I have in mind:
declare
cursor all_files is
select filename from xml_in; --xml_in is my Oracle directory where the files will live.
eachFile all_files%ROWTYPE;
begin
open all_files;
loop
fetch all_files into eachFile;
exit when all_files%NOTFOUND;
--Do my XML processing here
end loop;
close all_files;
end;
Is it possible to do this kind of processing on external files? If so, how can I get something that would function like the cursor described above to work?

The files are unknown to Oracle, I'm using an Oracle directory just as a save point for processing. I've got an external application written that will process the xml (actually, it calls an already-completed PL/SQL stored procedure) but I'd like to have portability between the different OS's.
Short answer to your question...No.

Need to create file in unix (oracle directory path)

Is it possible to create a file in oracle directory path (in unix folder).
I am using a dynamic procedure to create the External Tables, when the given pattern file is present the procedure will create the External table, if the file is not present then it should create an empty file so that the corresponding External table would return zero(0) records. It should not fail.
It has to be through plsql not using unix script.
UTL_FILE.FGETATTR(V_DIR_NAME, V_FILE_NAME, V_EXISTS, V_FILE_LENGTH, V_BLOCKSIZE);
IF v_exists=FALSE THEN
--------create an empty file
v_file_name:=empty_file;
end if;
--Create table script which will dynamically create the external table
v_sql := 'CREATE TABLE '||V_RX_NAME||' ( '||RTRIM(v_cols,', ')||' )' ||
' ORGANIZATION EXTERNAL '||
' ( TYPE ORACLE_LOADER '||
' DEFAULT DIRECTORY "'|| v_dir_name || '"'||

Creating a text file in an oracle directory

Hello all,
I created a directory in oracle called sampledata (create directory sampledata as 'c:sampledata'). How do I create a new text file in that directory? That's it.
Thanks,
Ad

I created a directory in oracle called sampledataYou mean you created with sys, right? I think only sys can create directories. Make sure you grant privileges to your user. So let's walk trough this:
connect sys@orcl as sysdba;
create or replace directory temp_directory as 'c:\temp';
grant read, write on directory temp_directory to scott;
connect scott@orcl;
declare
output_file utl_file.file_type;
begin
    output_file := utl_file.fopen('DIR_TEMP', 'test_file.txt', 'w');
    utl_file.put_line(f, 'Testing output file');
    utl_file.fclose(output_file);
end;

I granted priveleges to a different directory that I created. Take a look here:

Writing the file to a specific directory on server using DATASET

Hello Friends
I know that using dataset command we can create a file, write to a file, read from a file etc.,
But by default it uses the directory DIR_SAPUSERS which is the ./ directory.
But this particular directory DIR_SAPUSERS also has other system related log files etc.,
Is there a way to make the command DATASET write to a user created directory instead of this ./ ??
Any suggestions or comments will be highly appreciated.
Thanks
Ram

IF NOT p_ufile IS INITIAL.
OPEN DATASET p_ufile FOR INPUT IN TEXT MODE.
IF sy-subrc <> 0.
EXIT.
ENDIF.
here p_ufile will contain the path where ever u need to place the file i.e. use specific path.... ex: "usr/sap/bin/interface"

Writing an file to a specified directory

I have an application in Tomcat. In this application i write data into an xml-file. When i check this, i see that the file is written in the bin directory of tomcat. Now I want to write this file into another directory, for example: /tomcat/webbaps/catalog/orders/order.xml
Can someone tell me how my code to place it in this specified directory looks like?
Thx !

When you specify the file name, prefix it by the directory you want it stored in. You didn't show any code that explains how you are doing it now, so I'm not showing you any code that might be irrelevant. There are many ways to write an XML file to disk.

Upload a CSV file directly to an Oracle directory?

We have some existing packaged code that reads CSV files from an Oracle directory into the database via external tables. Currently, the files are placed in the directory via FTP, but we'd like to upload them via APEX if possible.
As far as I can tell, APEX file upload will store a file as a BLOB in an APEX table. Is there any way to re-direct the file upload to put file straight into the Oracle directory instead? The files will be copied from a Windows client to an Oracle server on Unix.
We're still on APEX v.3.2 unfortunately.
Edited by: chriswebster on Mar 31, 2011 10:05 AM

Similarly, we don't really want to have to extract a BLOB from the APEX file-upload table and re-create the CSV file either, as this seems like a lot of work to do a simple thing.

Not really, just a page process...
PROCEDURE blob2file (p_blob         BLOB,

How can I write more than 32k file in oracle directory

Hi experts,
I am struggling while I write more than 32k file size in oracle directory, and throws an error ‘ORA-06502: PL/SQL: numeric or value error, like this.
This is my procedure
declare
l_s_filename   UTL_FILE.file_type;
begin
   l_s_filename := UTL_FILE.fopen ('INFO_MIGRATION', 'finfinne.txt', 'W');
FOR rec
      IN ( SELECT SQL_REDO
              FROM V$LOGMNR_CONTENTS
             WHERE seg_owner <> 'SYS' AND username = 'GENTEST'
             AND TABLE_NAME NOT LIKE '%_TEMP'
                   AND OPERATION IN ('UPDATE','INSERT','DELETE')
          ORDER BY TIMESTAMP)
   LOOP
      UTL_FILE.put_line (l_s_filename, rec.SQL_REDO);
   END LOOP;
   UTL_FILE.fclose (l_s_filename);
end;can any please help me how can I overcome this problem
Thanks,
Arun

You can write by breaking it into small chunks. Also you can try to use DBMS_XSLPROCESSOR.CLOB2FILE. For UTL_FILE the code snippets may looks like
-- Read chunks of the CLOB and write them to the file
-- until complete.
   WHILE l_pos < l_blob_len
   LOOP
      DBMS_LOB.READ (rec.l_clob, l_amount, l_pos, l_buffer);
      UTL_FILE.put_line (l_file, l_buffer, FALSE);
      l_pos := l_pos + l_amount;
   END LOOP;

Error in writing to file.................................... Oracle9iV2 on RedHat7.3

What is causing the failure of the Oracle JDBC Development Drivers component during the Oracle9i installation, I'm getting the
Error in writing to file classes111_g.jar
If I skip this component then it keep on listing other files including a file.PDF file and I checked all the permissions so it is not a file permission error.
Could someone list the steps they took to set up JAVA on their Linux box and then what you had to add exactly to your ".bash_profile"
Perhaps this is what I'm doing wrong.
Thnx.

Your error has been completely addressed here http://www.puschitz.com/InstallingOracle9i.html. This is very informative. You may want to check this out before proceeding. The straight solution to this is when this error shows up, leave it open, find the native_threads/java file from the CD to the directory Oracle is asking for this. I had this problem and it turned out when I extracted and burnt it to a CD, it didn't copy the native_threads directory and others, so you want to check this as well.

Have you checked the obvious with the OS? Disk space, file permissions etc. because the first message may be all you need worry about.

Error in writing to file - Oracle

Dear All,
We have to upgrade Oracle from 10.2.0.2 to 11.2.0.2. For this we are applying patches till 10.2.0.4. OS is AIX 6.1.
Before proceeding I have stopped SAP, DB, Listerner and emctl also.
But after starting the patches we found the msg that, Error in writing to file 'oracle/SID/102_64/jdk/bin/libdbgmalloc.a'.
[/oracle/SID/102_64/jdk/jre/bin/libdbgmalloc.a(Cannot open or remove a file containing a running program.)]
Click 'Help' for more information.
Click 'Retry' to try again.
Click 'Ignore' to ignore this error and go on.
Click 'Cancel' to stop installation.
We are in the middle of installation where deinstallation has already passed. Please help us in fixing this issue. We tried ps -ef | grep libdbgmalloc.a to check the running status but didnt find that.
Thanks,
Rableen

Hi Rableen,
You can go ahead with the solution provided above. There would be no impact on system as we have done the same on our whole landscape and did not encounter any issue after multiple round of testings.
This happens because semaphore which uses jdk library files at OS level. You would not be able to locate any process related to that.
Once you rename libzip.a to libzip.a_old and click on retry, another file libzip.a of newer timestamp will be put by upgrade tool.
hostname:orasid 7> ls -rtl|grep libzip.a
-rwxr-xr-x 1 orasid dba 109588 20 Aug 2005 libzip.a_old
-rwxr-xr-x 1 orasid dba 109803 21 Apr 2008 libzip.a
hostname:orasid 7> pwd
/oracle/SID/102_64/jdk/jre/bin
hostname:orasid 7>
Nothing to worry after renaming as upgrade tool will put a new file of new date at the same place.
Also as you are going to upgrade 11G, directory 102_64 will not be used at all after 11G upgrade. A new directory structure will be created as /oracle/SID/11202.
Cheers !!!

I go to the directory and the file is there, around 95 megs. I have deleted it and retried, and I have tried just retrying. Nothing seems to make it go. Can anyone give me further suggestions for a fix?

Having the same problem,except its on Redhat 8.1 beta. Installer crashes when copying README.TXT part any luck??Is it failing on the linking part of the install??
