FTP Transport - ASCII vs Binary mode

I need to receive both ASCII files and Binary ( simple Pass thru) files into Oracle B2B using FTP. Also I need to send out ASCII files and Binary files using FTP to our different trading partners. How do I specify the mode of FTP as ASCII for one trading partner delivery channel vs Binary for another trading partner delivery channel? Is there an obvious parameter I am missing in the transport configuration? I would appreciate any help
Thanks

Unable to send file in binary mode to ftp server using AIR application

Hi, Can any one help me. i am trying to send local files to ftp server in binary mode from AIR application using sockets.
I cant use PASV mode for this FTP server because security restrictions. when i am trying to send Binary command i am always getting
error code 500 which is unrecognized command. I googled for solutions but i cant find any one using Binary mode to send data every example is using PASV mode to send
file.
code example:
private function upload():void{
sendCommand("binary ");
private function sendCommand(arg:String):void {
                                        arg +="\n";
                                        s.writeUTFBytes(arg);
                                        s.flush();
in response i am getting unrecognized command.

I'm successfully using an ftp example from http://http://projects.maliboo.pl/FlexFTP/
that I converted to spark and uses a popup progress window.
If you don't need to use sockets I can post a sample project.
I believe I still connect with PASV, but have no problems sending Binary files.
I don't think they're commands that are dependent on each other

Set up binary mode for backup over FTP

Hello!
I am about to set up the backup for Oracle DB from Tcode DB13.
My SAP systems are installed on Windows (64 Bit).
The backup data should be saved on the Unix-Samba share via FTP.
If I execute DB-Backup the backup is successful, BUT:
The file names are very strange e.g. S3FV1~6
The second problem is that the files will be written to the wrong directory
(I have set the path to "sap/backup" and the files will be written to "sap").
My question is:
I have heared about binary mode during backup procedure With which parameters in init<DBSID>.sap can I set up binary mode for the backup?
Which other FTP-server-parameters or settings in file init<DBSID>.sap are responsible for this issue?
Thank you very much
regards

Hi,
this program may help:
http://www.bombich.com/software/ccc.html (You need the older version for Panther)
You can use it to clone your internal HDD to your external one, and then clone your external one to your internal one after you erase (and write zeros to ensure everything is gone) using Disk utility (I can't vouch for the actual security of this, but 'apparently' if you do the highest setting it will be secure) after booting from an OS X DVD. This is depends on the drive having the ability to boot, however.
After you run Cabon Copy Cloner/Clone your HDD see if you can boot from the drive. (Hold option at startup). Unless there are issues with the specific drive model, your eMac should be able to boot from all FireWire devices.
I'm not sure where Tiger comes into this, however. (As you mention later in your post). The way I understand, you basically just want to erase zeros on your HDD and boot from it just as you acquired it (hence the cloning/re-cloning of the internal HDD).
Good Luck!

NFS or FTP transport protocol

what is the difference between NFS and FTP transport protocol? and when do we use them?
Regards,
Ashish Goyal

NFS stands for File System.
Both of NFS and FTP should make the following specifications for file:
File name schema:
 Name of the file
File Construction Mode:
Create file, append to existing file, or specify additional parameters for the file name
File Type:
Binary or text file (in the case of the latter also specify the file encoding as a code page)
Operating System Command:
To be executed after successful processing (you can use placeholders for the file name)
Additionally,If you specify NFS as the transport protocol, the only other specification you need to make is the Target Directory in which the file is to be generated.
But if you want use FTP, following specifications should be made:
Server
 Host name or IP address of the FTP server
Port
 Port number of the FTP server (default: 21)
Connect Mode
 The connection can be permanently open, or it can be established for each file transfer
Transfer Mode
 Text or binary data transfer
Put File
 Direct or temporary file (collected before final transfer)
Folder
 Target folder for the file
Logon Data
 User/password, or anonymous (anonymous/anonymous)
Check this one

Ftp and ascii

While accessing a windows ftp server, I sometimes get the following:
sun.net.ftp.FtpProtocolException: ASCII mode data connection for file list.
My code is very simple:
          final String baseAddress = "ftp://" + username + ":" + password + "@" + servername;
          final URL url = new URL(baseAddress + s);
          final URLConnection connection = url.openConnection();
          final InputStream inputStream = connection.getInputStream();
          return inputStream;I would always prefer a binary connection (I would be happy if there was no ascii connection at all), but I've found no way how to set it up here.

ASCII transfer is much more a bug than a feature:
1. nobody really needs it, "\r\n" works in unix quite well, "\n" work in dos-like systems, too.
2. any such transformation I can make in a few seconds: string.replaceAll("\r\n", "\n").
3. any such transformation is a desaster and can NOT be undone if applied on a "binary" file.
4. because of this stupid thing my prg lodig data via ftp sometimes fails.
But forget it. The question is: how can I switch URL.openConnection() to binary.

What is the diffrence between ASCII and BIN mode

Hello All,
What is the diffrence between ASCII and BIN mode
Regards,
Lisa.

'ASC' :
ASCII format. The table is transferred as text. The conversion exits are
carried out. The output format additionally depends on the parameters
CODEPAGE, TRUNC_TRAILING_BLANKS, and TRUNC_TRAILING_BLANKS_EOL.
'IBM' :
ASCII format with IBM codepage conversion (DOS). This format correspond
to the 'ASC' format when using target codepage 1103. This codepage is
often used for data exchange by disc.
'DAT' :
Column-by-column transfer. With this format, the data is transferred as
with ASC text. However, no conversion exists are carried out and the
columns are separated by tab characters. This format creates files that
can be uploaded again with gui_upload or ws_upload.
'DBF' :
The data is downloaded in dBase format. Because in this format the file
types of the individual columns are included, import problems, for
example, into Microsoft Excel can be avoided, especially when
interpreting numeric values.
'WK1' :
The data is downloaded in Lotus 1-2-3 format.
'BIN' :
Binary format. The data is transferred in binary format. There is no
formatting and no codepage conversion. The data is interpreted row by
row and not formatted in columns. Specify the length of the data in
parameter BIN_FILESIZE. The table should consist of a column of type X,
because especially in Unicode systems the conversion of structured data
into binary data leads to errors.

OSB 11g - FTP Transport - Active or Passive connections?

Hi,
When we create a Proxy Service in OSB to use FTP transport, which type of connection OSB establishes with the server? Is it active FTP or passive FTP conecction?
Thanks,
Sanjay
Edited by: Sanjay Bharatiya on 20-Dec-2010 11:46 AM

OSB uses passive mode for proxy services and active mode for business services. There is a patch available which will make both proxy and business services to use passive mode. If you need the patch please open a Service Request in MyOracle Support and mention the support Note (860423.1)
Passive mode is desired if you want to open the firewall ports, if any, from OSB server to FTP server only and not other way from FTP Server to OSB server.

How to code j2ssh SFTP in Binary mode??

Dear Friends:
I use java to code j2ssh SFTP, but I did not know How to use j2ssh send/retrieve file in binary mode or ASCII mode, Please advise if any good suggestion.

Regular expressions for file/FTP transport within OSB. How?

The OSB transport/polling guides say for the FILE, FTP and SFTP transports that the "File Mask" can be a Regular Expression but I can't get it to pick up files this way. Is there some trick to enabling regular expression mode or some strange syntax required?
For example I set up a very simple pattern of [A-Z]+ which should match any filename with one or more uppercase alphabetic characters only, but it does not pick up anything. It seems only to support the usual wildcard * operator in the non-regular expression mode.
Any help much appreciated.

Good point, but if you think about this description, you have to realize it just doesn't make sense. Again ...
Enter a regular expression to select the files that you want to pick from the directory. The default value is \*.*The problem is that \*.* is not a regular expression at all. :-)
1. The documentation is a mess in this particular point.
2. FTP servers (at least those I have experienced) don't have a support for regular expressions.
So I guess you can use only wildcards and not regular expressions with FTP transport.

Issue in trasfering records to file using Transfer (in Binary mode)

Hi all,
I am using a trasfer statement to write the contents of internal table onto a file in Apllication server.
My code is
   LOOP AT i_file.
       TRANSFER i_file-rec_data TO i_pf_names-v_name.
   ENDLOOP
I am opening the file in binary mode.Its not writing the second record totally. Each of my record is 432 characters in length. Irrespective of no. of records in my internal table its writing only 1 rec completely and half of second record.
I am aware that opening a file in binary mode ignores the line breaks.
So, opening in binary mode should write 1000 characters. Its writing 511 characters and stopping. Its not writing further records though my internal table is having records.
Can you please help.

Hi,
If you are viewing the application server file in AL11, you wont be able to view the total length of the file even though it is written. To confirm this use the transaction CG3Y and download the application server to presentation server and check if the whole of the record is written

Vikranth

What is difference between TEXT mode and BINARY mode?

Hi,
          What is difference between TEXT mode and BINARY mode? In TEXT mode what is "ENCODING DEFAULT".
OPEN DATASET wl_filename FOR INPUT
                          IN TEXT MODE ENCODING DEFAULT.
OPEN DATASET wl_filename FOR INPUT
                          IN BINARY MODE .

Hi vishnu,
1. files like .TXT files are considered to be text,
   and other files like .EXE . DOC etc are binary files.
2. In text files, after each line, there are two
   internal binary characters
one for line feed and another one for newline.
3. But, we don't have any meaning for it,
   when we view such files in notepad, for eg.
   Hence, to only get the understandable content,
   we should open such TXT files, in text mode.
(we can also open them in binary mode,
but we will get two extra characters after each line,
   and such two extra characters are meaningless
for interpreting the text)
4. In binary mode, each byte by byte is considered,
   without any meaning.
regards,
amit m.

Open data set from Text mode to Binary mode

Hello All,
In a program i am using the command
    OPEN DATASET file FOR OUTPUT IN TEXT MODE
    ENCODING NON-UNICODE IGNORING CONVERSION ERRORS.
Now i want to change this open data set to binary mode. I mean to change the command like below.
OPEN DATASET file FOR OUTPUT IN BINARY MODE.
when i do this. the output in the file is totally changing. I mean previously i have some text now i have some diffrent characters.
How can i use this command with out change in the output as previous output. Please tell me the changes and why i have to do.
OPEN DATASET file FOR OUTPUT IN BINARY MODE.

Text Mode means that the records in the file have a carriage return marking the end of each record.
Binary Mode means the file is a string of data.
You can't read a text file in BINARY MODE, or a binary file in TEXT MODE.
If you are changing the mode, then you must be supplied with a file in the new mode.

Open data set problem with binary mode

Hi everyone,
I am trying to read into a buffer the content of a binary file (like Excel) and to write that content file using open data set into a folder destination.
The file destination has a size diferent than from the original one and cannot be open.
Here is the code.
DATA: lv_file_name(100),
         lt_content LIKE sdokcntbin OCCURS 0 WITH HEADER LINE.
MOVE '\computerTestA1.xls' TO lv_file_name.
OPEN DATASET lv_file_name FOR INPUT IN BINARY MODE.
IF sy-subrc NE 0.
    EXIT.
ENDIF.
DO.
    READ DATASET lv_file_name INTO lt_content-line.
    IF sy-subrc NE 0.
      EXIT.
    ENDIF.
    APPEND lt_content.
ENDDO.
CLOSE DATASET lv_file_name.
* DELETE DATASET lv_file_name.
CLEAR: lv_file_name.
MOVE '\computerTestB2.xls' TO lv_file_name.
OPEN DATASET lv_file_name FOR OUTPUT IN BINARY MODE.
IF sy-subrc NE 0.
    EXIT.
ENDIF.
LOOP AT lt_content.
    TRANSFER lt_content-line TO lv_file_name.
ENDLOOP.
CLOSE DATASET lv_file_name.
THanks in advance.

Hi,
I solve the problem.
In fact, when I try to write the last line of lt_content, it does write all the line even if this line is not full of data.
Solution :
DATA: lv_file_name(100),
         lt_content LIKE sdokcntbin OCCURS 0 WITH HEADER LINE,
         alen TYPE i,
         pos TYPE i.
MOVE '\mr0221TestA1.xls' TO lv_file_name.
OPEN DATASET lv_file_name FOR INPUT IN BINARY MODE.
IF sy-subrc NE 0.
    EXIT.
ENDIF.
SET DATASET lv_file_name POSITION END OF FILE.
GET DATASET lv_file_name POSITION pos.
SET DATASET lv_file_name POSITION 0.
DO.
    CLEAR lt_content.
    READ DATASET lv_file_name INTO lt_content-line ACTUAL LENGTH alen .
    IF sy-subrc NE 0.
      APPEND lt_content.
      EXIT.
    ENDIF.
    APPEND lt_content.
ENDDO.
CLOSE DATASET lv_file_name.
* DELETE DATASET lv_file_name.
CLEAR: lv_file_name.
MOVE '\mr0221TestB2.xls' TO lv_file_name.
OPEN DATASET lv_file_name FOR OUTPUT IN BINARY MODE.
IF sy-subrc NE 0.
    EXIT.
ENDIF.
LOOP AT lt_content.
    AT LAST.
      TRANSFER lt_content-line TO lv_file_name LENGTH alen.
      EXIT.
    ENDAT.
    TRANSFER lt_content-line TO lv_file_name.
ENDLOOP.
CLOSE DATASET lv_file_name.
Thanks.

Data transfer from application server to sap system in binary mode

HI,
Syntax for reading the file
OPEN DATASET file FOR INPUT IN BINARY MODE
if sy-subrc = 0.
DO.
READ DATASET file INTO wa_record.
ENDDO.
CLOSE DATASET file.
endif.
syntax for writing file.
OPEN DATASET file FOR OUTPUT IN BINARY MODE .
if sy-subrc = 0.
transfer wa_record to file.
CLOSE DATASET file.
endif.
You can also transfer file from application server to presentation server using transaction CG3Y by specifying source path(app ser),destination path(presentation ser) and tranfer format (BIN).
To copy the file from one location to other location in application server
use the FM 'ARCHIVFILE_SERVER_TO_SERVER'
reward points if needful..

How to read file header/open filein binary mode

i am using FileConnenction API to read from a file. how can i open a file in binary mode so that i can read file header. In other words i want to open a file in binary mode.

You can always try looking at the [Header Signatures|http://www.techpathways.com/uploads/headersig.txt]. But it would probably be easier to adjust your application so it doesn't have to guess.
