Move files from server to client

I have create txt file in server directory using UTL_FILE package,
and I put in the directory in server.
Server platform is linux. and client platform in Windows.
What I want to ask is there any possibilities to copy that file from server to client using pl/sql ? could all of you "The Gurus" give me a script example ?
Thanks a lot.

indra

> What I want to ask is there any possibilities to copy that file from server

No. Not really.
Think about it.. the file is on the server. PL/SQL code executes inside the Oracle server session that is servicing the client.
Just how is PL/SQL (on the server) suppose to reach out and push that file to a client's file system and directory?
PL/SQL cannot do this. You need something on the client that will accept the file. You need something in-between the client and PL/SQL that will handle the transfer of the file. This something can be ftp, scp, tftp, NetBIOS etc.
Anyway you look at this, it does not make sense. You are turning the server into the client that needs to push the file. You are turning the client into a server that needs to accept the file.
Why? This is contrary to the basic client-server RDBMS architecture. You are adding more complexities and more moving parts to the architecture by forcing a swap of client and server roles. The are now a far greater likelihood of errors and bugs and failures.
It does not make sense to do it this way.
What is the business requirement you are trying to satisfy? Instead of us trying to help you to hack a flawed solution, let us rather assist you in determining the correct and proper solution.

How can i transfer more than one file from server to client

Hi,
our requirement is transfer more than one files from server to client using the
webutil_file_transfer.as_to_client_with_progress.One file transfer is already working in our system.If anybody know the solution please inform
regards
mat

just an idea ...
for this purpose let us put aside security concerns and other potential problems....
-- Get the content of a server directory with Filter and create zip file
1) create a class that implements java.io.FilenameFilter ...
2) define accept() method ...
3) call File.list() with the filter as a parameter. The returned array of strings will have all the names that passed through the accept() filter
4) use java.util.Zip to create ZIP file on the server side
-- I think it is better to create this functionality as a separate Java class, put it in required folder and after it
-- use Forms->Program->"Import Java class" to create pl/sql wrappers, than to create wrappers for all classes and code in pl/sql
5) use webutil to transfer file on the client
6) use Java on client side to unzip transferred file
if you think this is not too complicated, you should try ...

Vladimir

Drive Redirection virtual channel hangs when copying a file from server to client over RDP 8.1

Problem Summary:
A UTF-8 without BOM Web RoE XML file output from a line of business application will not drag and drop copy nor copy/paste from a Server 2012 R2 RD Session Host running RD Gateway to a Windows 7 Remote Desktop client over an RDP 8.1 connection and the Drive
Redirection virtual channel hangs. The same issue affects a test client/server with only Remote Desktop enabled on the server.
Other files copy with no issue. See below for more info.
Environment:
Server 2012 R2 Standard v6.3.9600 Build 9600
the production server runs RDS Session Host and RD Gateway roles (on the same server). BUT,
the issue can be reproduced on a test machine running this OS with simply Remote Desktop enabled for Remote Administration
Windows 7 Pro w SP1v6.1.7601 SP1 Build 7601 running updates to support RDP 8.1
More Information:
-the file is a UTF-8 w/o BOM (Byte Order Marker) file containing XML data and has a .BLK extension. It is a Web Record of Employment (RoE) data file exported from the Maestro accounting application.
-the XML file that does not copy does successfully validate against CRA's validation XML Schema for Web RoE files
-Video redirection is NOT AFFECTED and continues to work
-the Drive Redirection virtual channel can be re-established by disconnecting/reconnecting
-when the copy fails, a file is created on the client and is a similar size to the original. However, the contents are incomplete. The file appears blank but CTRL-A shows whitespace
-we can copy the contents into a file created with Notepad and then that file, which used to copy, will then NOT copy
-the issue affects another Server 2012 R2 test installation, not just the production server
-it also affects other client Win7 Pro systems against affected server
-the issue is uni-directional i.e. copy fails server to client but succeeds client to server
-I don't notice any event log entries at the time I attempt to copy the file.
What DOES WORK
-downgrading to RDP 7.1 on the client WORKS
-modifying the file > 2 characters -- either changing existing characters or adding characters (CRLFs) WORKS
-compressing the file WORKS e.g. to a ZIP file
-copying OTHER files of smaller, same, and larger sizes WORKS
What DOES NOT WORK?
-changing the name and/or extension does not work
-copying and pasting affected content into a text file that used to have different content and did copy before, then does not work
-Disabling SMB3 and SMB2 does not work
-modifying TCP auto-tuning does not work
-disabling WinFW on both client and server does not work
As noted above, if I modify the affected file to sanitize it's contents, it will work, so it's not much help. I'm going to try to get a sample file exported that I can upload since I can't give you the original.
Your help is greatly appreciated!
Thanks.
Kevin

Hi Dharmesh,
Thanks for your reply!
The issue does seem to affect multiple users. I'm not fully clear on whether it's multiple users and the same employee's file, but I suspect so.
The issue happens with a specific XML file and I've since determined that it seems to affect the exported RoE XML file for one employee (record?) in the software. Other employees appear to work.
The biggest issue is that there's limited support from the vendor in this scenario. Their app is supported on 2012 R2 RDS.
What I can't quite wrap my head around are
why does it work in RDP 7.1 but not 8.1? What differences between the two for drive redirection would have it work in 7.1 and not 8.1?
when I examine the affected file, it really doesn't appear any different than one that works. I used Notepad++ and it shows the encoding as the same and there doesn't appear to be any invalid characters in the affected file. I wondered
if there was some string of characters that was being misinterpreted by RDP or some other operation and blocked somehow but besides having disabled AV and firewall software on both ends, I'm not sure what else I could change to test that further
Since it seems to affect only the one employee's XML file AND since modifying that file to change details in order to post it online would then make that file able to be copied, it seems I won't be able to post a sample. Too bad.

How to download file from server to client's local ??

How to download a file from the server to the client's local machine in a particular folder without users intervention ie. 'Save As" prompt of the browser should be avoided and if the client clicks on "Download" button, the file should get automaticaly downloaded to say, "c:/reports/' on his/her local machine. This is for Java based web appliaction.

Help :- Send Large File From Server To Client

Hey guys, I am stuck with a problem.Hope u guys might be able to help me out. My problem is :-
From client i am doing an operation which results in calculation of results by server and saving a file on the server..But i want to see what results have been computed by the server and hence i want to stream that file back to the client..
The file may be of 100MB as well , that is, the size of the file may be huge.
I want u guys to tell me how to stream that file back to the client..I tried returning byte array which gets serialized and then received at client side but as i said the file may be huge so memory problem may arise, so returning byte[] from function is not a good solution..
I am looking something where server can send the file back to the client in chunks..Client keeps receiving these chucks and keep putting them in the file.
So how to make server send file in chunks??Also, i don't know the hostname and ports...so sockets i can't use...
Any Another way to do it...??
is PipedStream a solution??
Please guys, help me
Thanks in advance

So i wanted to know if we can without using sockets send file back to Client..I would have the RMI return the connection details where the result can be obtains, .e.g with hostname, port, and file name to use.
I would suggest trying to compress the stream as well (just wrapp the stream on the sender/reciever), especially for files over 1 MB.
Tell me something abt PipedStreams as well..If they are of any use here or not?I don't see how. PipedStreams can be used to share data between threads in the same process.
If RMI is your only choice you can perform a method which would return alot of data and have seperate methods to download portions of it.
e.g.
public int loadBigFile(String filename); // returns the number of portions.
public byte[] returnPortion(int n);
int portions = rmi.loadBigFile("my-big-file.xml");
for(int i=0;i<portions;i++) {
byte[] bytes = rmi.returnPortion(i);
// do something with bytes.
}You can have the server cleanup the file when the last portion is read.

Passing contents of file from server to client

We have a Visual Basic 6 application that uses OO4O to access a 9i database.
We have a requirement to retrieve a text file from the database server and display the contents in our VB 6 client.
We already do this for small files. Basically we call a stored procedure that reads the file using utl_file and returns the contents of the file in a OUT_VALUE_LONG variable which VB then displays.
The issue is that we now need to do the same but for a much bigger file. Is there a limit to the amount of data we can pass in an OUT_VALUE_LONG?
If there is a limit, what other options do we have?

I'm not quite sure I understand your question, but in case I do, here goes. If you're ssh'd into another machine, you're using that machine. Dragging something from your local finder into a terminal ssh session, if I'm not mistaken,hopelessly munges the path. The ssh session puts you on the other client. Trying to figure out what happens when you drag a file from your local finder to a terminal session on a remote host starts to make my head hurt. I think typing the entire path, or just navigation to the right directory would be the best bet. You can do this on multiple clients through ARD, and I imagine you could script the process as well (already posted).

What could the problem be?

What could the problem be?
The FIRST problem is that your code has NO exception handler and is just HIDING any exceptions that might be occuring.
Why are you doing that?
Code should either HANDLE an exception or let it bubble up to the caller.
Add exception handling to the code and rerun it to see if any exceptions are occuring that could be affecting the outcome.
The SECOND problem is that you are NOT showing the client side that is being used and any code that might be causing/handling/hiding exceptions on the client side.
Post a simple test case that includes both server and client that demonstrates the problem you have.

How to save file from server to client machine

Hi,
By using POI library i'm writing values to the existing excel sheet which is available in server. After i written values to the excel, i want to save the same file to the client machine.
How to achieve this.
I googled about this, but still i didn't get any clear idea.
Thanks in advance,
SAN

Sameera,
No, i can't understand what is the meaning of the following code:
public void doDownload(FacesContext facesContext, OutputStream outputStream) {
// write the neccessary code to get the download data from the Model
String data = getDownloadData();
// save to the output stream
try {
OutputStreamWriter writer = new OutputStreamWriter(outputStream,"UTF-8");
writer.write(data);
writer.close();
outputStream.close();
} catch (IOException e) {
// handle I/O exceptions
can you please explain this code little more.

How to download a file from server to client m/c

hi
my requirement is,
a form is displayed to user with a download button and
onclick of download ,user will see a box with options open,save,cancel.
if user clicks on open /save ,how to get the info about download is complete on client side because i need to set a flag in database ,
as Downloaded once the download is complete on client side
my problem is ,in the action of form the path given is of servlet class
having code of
setheader and setcontenttype as attachment but on click of download button it is opening the servlet instead of the required file,
means it is opening the page specified in action of form ,
what can be done abt it??/

Please post your code using code tags (click on CODE above the text area, when posting)
response.setContentType("application/octet-stream");Why octet-stream? Set the correct mime-type.
String disHeader = "Attachment; Filename=\"filename\"";The filename should just be the file's name. Not the complete path to the file! This will tell anyone where the file is located on the server. It's also inconvenient because by default,the browser will suggest it as the name for the download.
Your way of writing to the output stream is just plain wrong. See this snippet (picked from [http://balusc.blogspot.com/2007/07/fileservlet.html])
        BufferedInputStream input = null;
        BufferedOutputStream output = null;
        try {
            // Open streams.
            input = new BufferedInputStream(new FileInputStream(file), DEFAULT_BUFFER_SIZE);
            output = new BufferedOutputStream(response.getOutputStream(), DEFAULT_BUFFER_SIZE);
            // Write file contents to response.
            byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];
            int length;
            while ((length = input.read(buffer)) > 0) {
                output.write(buffer, 0, length);
            // Finalize task.
            output.flush();
        } finally {
            // Gently close streams.
            close(output);
            close(input);
        }

How do I trace users who delete or move files from server

We're in the process of setting up our XServe that will run on OS 10.6 and we would like to find out if it is possible to trace which user deleted which file or document from the server in case it happens. We want to do this because we will be having particular folders in which there are more than two users who have permission to remove files.
I tried searching answers in this forum but I'm probably not doing it the right way. So my apologies if it's already asked and answered, and thanks if someone can point me to such.

The answer relies on what access options the clients have to the directory in question.
If the users can ssh to the server and get a command line, you're out of luck.
If the users are using AFP, you can up the logging level on the AFP server to include file deletes.
The same goes for FTP and SMB, but there's nothing for NFS.
Other access methods may have similar options, too.

Vendor application only call the URL with parameter
to get the File in secured manner. OK.
the Vendor
application may be in java or not..NET ?
so in that case
also do.so what ? is your problem solved or not ?
you may need to make webservices.

Download Files from Server to Client

I have a flex application that sends data to a php page that
then generates a pdf file and returns the name of that file to the
application. All of that works fine. The problems start when I try
to then download that file to the client.
This is the Flex client code:
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
import mx.rpc.events.ResultEvent;
[Bindable]
private var pdfFiles:ArrayCollection;
private function requestPDFHandler (event:ResultEvent):void
if( event.result.Files == null ) { /* Table is empty */
/*Do Nothing*/
}else if( event.result.Files.File is ObjectProxy ) { /*
Table has only one record */
pdfFiles = new ArrayCollection( [event.result.Files.File] );
}else { /* Table has many records */
pdfFiles = event.result.Files.File as ArrayCollection;
downloadPDF();
private function getPDF():void {
requestPDF.send();
import flash.display.Sprite;
import flash.events.*;
import flash.net.FileReference;
import flash.net.URLRequest;
import flash.net.URLRequestMethod;
private function downloadPDF():void {
//trace (pdfFiles.list.getItemAt(0).FileName);
var DOWNLOAD_URL:String = "
http://" + dbLoc + "/PDF/tmp/" +
pdfFiles.list.getItemAt(0).FileName;
//trace(DOWNLOAD_URL);
var fr:FileReference = new FileReference();
var request:URLRequest = new URLRequest();
request.url = DOWNLOAD_URL;
//configureListeners(fr);
fr.addEventListener(Event.CANCEL, cancelHandler);
fr.download(request,"Product List.pdf");
private function cancelHandler(event:Event):void {
trace("cancelHandler: " + event);
]]>
</mx:Script>
<mx:HTTPService id="requestPDF" url="
http://{dbLoc}/PDF/MakePDFDoc.php"
method="POST" result="requestPDFHandler(event)">
<mx:request xmlns="">
<ProdGroupID>{cboProdGroup.selectedItem.ID}</ProdGroupID><CurrencyID>{cboCurrency.selecte dItem.ID}</CurrencyID>
</mx:request>
</mx:HTTPService>
<mx:Button x="574" y="804" label="Save as PDF"
width="144" height="34" fontFamily="Verdana" fontSize="12"
cornerRadius="12" id="btnSavePDF" enabled="true"
fillColors="[#33332d, #33332d]" fillAlphas="[1.0, 1.0]"
color="#ffffff" textRollOverColor="#808080"
textSelectedColor="#808080" borderColor="#000000"
mouseUp="getPDF()"/>
When the button is clicked it sends to the php page fine and
recieves the name of the file. When it gets to
"fr.download(request,"Product List.pdf");" in the downloadPDF
function, the 'fr:FileReference' object gives me this error -
"Error: Error #2037: Functions called in incorrect sequence, or
earlier call was unsuccessful.". I don't understand what is causing
the error. Any suggestions?

Basically, you can try to:
1. create a ServerSocket to listen to client request.
2. once a request is received create a thread to handle that connection.
3. find out what file does the client want.
4. read the file into a byte array.
5. flush the byte array back to the socket back to the client.
6. once the client receive the content, start writing it to disk.
You have to look into classes like ServerSocket, Socket, DataInputStream, DataOutputStream, FileInputStream, FileOutputStream, and etc.
There are other ways to do it.
Hope this helps.

It generating an error Is there a way to move files from server to another in coldfusion

You talk to your network administrator(s) and ask them what permissions have been assigned to the user that the ColdFusion service|demeon is running as.
P.S. By default, on a windows machine, ColdFusion runs as a "localSystem" user, which usually has *no* permissions to other systems.

Applet question, how to download resource files from server

hi,
i am new at applet world.
i have an applet that reads some resource, data and configuration files. so i need to download these files from server to client. i did some resarch and could not find how to download files from server in an applet application.
how can i do this task?
thank you for your answers.

You may want to distinguish between 'resources' and data/configuration files.
'Resources' are non-class files that are part of your application, i.e without them the application would simply not work, just like class files.
Those are typically images, sounds or resource bundles (GUI elements translated to different languages) that nobody except you, the developer, would touch (when releasing an upgrade or a patch).
Those should just go into the applet jar or additional jars named in the applet tag.
Data/configuration files, that may be changed by others than the developers, should be made available through HTTP, just like the applet jar itself. The applet will have (read) access to them using java.net.URLConnection.
