Writing Datalog Files with record length

How do I write a Datalog File with a record length of 128 int16s?

Each I16 number in LabVIEW that you write uses 2 bytes because 8 bits equals 1 byte. If you write 128 numbers, the file will be 256 bytes long. You can modify the VI to write I32 (4 bytes) or I8 (1 byte) just by changing the representation of the number. You also need to change the subVI that does the actual writing (Write File+ [I16].vi). Be sure to rename the VIs that you change. I would think that your Fortran program would work as long as the data types match.

Send a flat file with fixed lengths to XI 3.0 using a Central File Adapter?

Hello,
I'm wondering if someone have experience setting up conversion for different record structures. The example shown,
/people/michal.krawczyk2/blog/2004/12/15/how-to-send-a-flat-file-with-fixed-lengths-to-xi-30-using-a-central-file-adapter,
(in a greate way) only picture one kind of structure.
How should it be done if the file would contain
10Mat1
20100PCS
The first record structure has columns
ID(2),Material(10)
The second redcord structure has columns
ID(2),Quantity(3), Unit of messure (3)

Interface output file : tab limited vs flat file with fixed length

hey guys,
any idea on difference b/w to file type : flat file with fixed length or tab limited file
thanks

Tab Delimited:
Two Field are seperated by a TAB
eg. SANJAY SINGH
First field is First Name and Second is Sir Name.
Nth field will be after N -1 tab
Fixed Length:
Every field has a fixed starting position and length
eg. SANJAY SINGH
Here First field start from Position 1 and has lenght 10 and 2nd field start from 11th postion and has lenght 10.
Fixed Length -> The lenght of each field is fixed, while in tab delimited the lenght of field is not fixed but we know it ends when the Seperatot (Tab) is encountered.

Suppress writing cache files with rwrun.exe

Hello,
we`re using rwrun.exe (9.0.4.2.0) with parameters to create pdf-files in a loop:
REPORT=mytest.rdf
USERID=scott/tiger@orcl
BLANKPAGES=no
DESTYPE=file
DESNAME=mytest.pdf
DESFORMAT=PDF
OUTPUTIMAGEFORMAT=GIF
CACHELOB=NO
Each process write a cache file in the directory \reports\cache. Reports eats the hard disk :-(
I`ve found the EXPIRATION command in the documentation, which defines the point in time when the report output should be deleted from the cache. But this command strictly runs with rwclient.exe and reports server, but Reports server isn`t installed on our server.
Can we suppress writing cache files with rwrun.exe?
Steffen

Hello,
Why don't you add a command del in your loop ?
Example:
del %ORACLE_HOME%\reports\cache\*.*

Transferring data to a flat file with a length greater than 255 bytes??

Is there a way to do this? At the end of the month, my dataset will reach a length of anywhere between 271 and 335. Even though I have the transfer field setup with a length of 512, I am only getting 255 characters worth of data when I pull the flat file in from the server.
Has anyone discovered a way to handle this? I cannot break the record up into blocks of 255, the Transfer has to be able to handle something greater than a length of 255.
Many Thanks!

Writing to file with ObjectOutputStream

ApartmentWriterProgram asks information about apartments
and saves it to a file.
For some reason it doesnt save information, it writes:
Writing to file "+file+ " failed.
So there happens IOException in the method write(Apartment apartment).
Or in the run().
I dont know what's wrong. Do you?
public class ApartmentFileHandler extends Object implements Serializable {
 private OutputStream outStream;
 private ObjectOutputStream obStream;
 private String filePath;
 public ApartmentFileHandler(String filePath) {
 this.filePath = filePath;
/** Writes the given apartment data in the file. If the file already
exists, the old contents are overwritten.
Parameters:
apartment - the apartment to be written in the file
Throws:
IOException - if other problems arose when handling the file (e.g. the
file could not be written)
 public void write(Apartment apartment)
 throws IOException {
 outStream = new FileOutputStream(filePath);
 obStream = new ObjectOutputStream(outStream);
 obStream.writeObject(apartment);
import java.io.*;
import java.util.*;
public class ApartmentWriterProgram
extends Object
 private KeyboardReader keyboardReader;
 private List roomsInList;
 private Room[] rooms;
 private int numberOfRooms;
 private String file;
 public ApartmentWriterProgram()
 this.keyboardReader = new KeyboardReader();
 this.roomsInList = new ArrayList();
 this.rooms = new Room [numberOfRooms];
/** Runs the writer program. The program asks the user for some
apartment data and a file name, and saves the data in the file. */
 public void run() {
 try {
 numberOfRooms = keyboardReader.getInt("Give number of rooms: ");
 for (int i =1; i<numberOfRooms+1; i++) {
 String type =keyboardReader.getString("Give " +i+ ". " + "type of the room: ");
 double area =keyboardReader.getDouble("Give " +i+ ". " + "area of room: ");
 Room room= new Room(type, area);
 this.roomsInList.add(huone);
 roomsInList.toArray(rooms);
 Apartment apartment = new Apartment(rooms);
 System.out.println();
 file = keyboardReader.getString("Give name of the file: ");
 ApartmentFileHandler handler = new ApartmentFileHandler(file);
 handler.write(apartment);
 } catch (IOException ioe) {
 System.out.println("Writing to file "+file+ " failed.");
 public static void main(String[] args) {
 ApartmentWriterProgram program = new ApartmentWriterProgram();
 program.run();
}

There is nothing to gain in not putting the throws IOException in the write method, since the exception object will have the information about the actual problem.
Is this a typo for the this post? this.roomsInList.add(huone); should be room nes pas.
What exception is actually thrown? To find out useSystem.out.println("Exception: " + ioe);Then wonder why you have the AppartmentFileHandler implement Serializable when you are not writing that object to the file.

Trouble writing to file with FileWriter

Hey I'm pretty new to Java and even newer to file classes so I'd appreciate it you could look over what I've done. My FlashCard object has its own toString() method which prints out what I want it to so basically all I need to know is why it doesn't print anything?
File f;
//..Constructors and other methods for a JFrame
 private void printList() throws IOException
 writer = new PrintWriter(new BufferedWriter(new FileWriter(f)), true); //f is a File object declared below
 writer.println("test");
 java.util.Iterator<FlashCard> e = cards.iterator();
 String s = "";
 while(e.hasNext())
 s = "" + e.next();
 writer.println(s);
 System.out.println(s); //Debugging line, prints out what i want to be put in the file correctly!
 writer.close();
 FileWriter writer2 = new FileWriter(f, true);
 writer2.write("hi");
//....more code
private class ClickListener //subclass of the class containing the code above
 implements ActionListener
 @Override
 public void actionPerformed(ActionEvent e)
 if (e.getSource() == create)
 boolean temp = false;
 String fileName = "c:\\FlashCards\\";
 f = new File(fileName);
 f.mkdir();
 f = new File(fileName + stackName.getText() + ".txt");
 try {
 temp = f.createNewFile();
 } catch (IOException e1) {
 //...More code here for responding to file not being created successfully
 f.setWritable(true);
 control.currentFile = f;
 }This the the only code I thought to be relevant but if there's a declaration you need that I left out let me know! The annoying thing is I copied this from another class I wrote (with modifications of course) and it works perfectly, no problems!
Thanks in advance!

OK I've done the things you've mentioned, thank you for me notice i was missing some code organization. The problem unfortunately is not yet solved but now I think I have a better idea of what the problem is! Here's the code:
This is what I'm using to make a file
private void createFile()
 boolean temp = false;
 String fileName = "c:\\FlashCards\\";
 f = new File(fileName);
 f.mkdir();
 f = new File(fileName + stackName.getText() + ".txt");
 try {
 temp = f.createNewFile();
 } catch (IOException e1) {
 //TODO fill in exception catchs
 if(temp)
 //Do something
 else
 JOptionPane.showMessageDialog(addCard, "File Name Already Exists");
 return;
 }And this is where the file is being used by a writer:
 private void printList() throws IOException
 String temp = f.getAbsolutePath();
 PrintWriter writer = new PrintWriter(new BufferedWriter(new FileWriter(new File(temp), true)), true);
 java.util.Iterator<FlashCard> i = cards.iterator();
 while(i.hasNext())
 writer.println(i.next()); //TODO fix this writer so that it prints properly onto the document!!
 writer.close();
 }The problem I think is either caused by a) the new File doesn't like properly to the FileWriter for some reason or b) the file I've made does not work for output for some reason. I think this because I can make a new file with a literal pathname such as "c:\\file.txt" and it works fine but as soon as I use my file f to make it it doesn't print anything out!! any ideas?

Writing a file with the OutputStream

I'm trying to upload a file using Java's included ftp functionality.
currently I'm trying to figure out how to upload a file. The connection and works.
The code I found for the ftp connection indicated that I should use the following code to upload..
URLConnection urlc = url.openConnection();
OutputStream os = urlc.getOutputStream();
I've read the documentation for the outputstream and looked for help tutorials on the web etc, but still haven't been able to figure out what I'm doing.
I need the output stream to write a file to the ftp server. I can get it to put a file there, but so far its just been an empty file. How do I get it to actually write the file with its contents etc.
thanks for the help

never mind :) I think I figured it out.
I just created a File object for the file, then opened a fileinputstream to read the file in and wrote that output using the output stream.
it seems to work.

Adapter file receiver - file with fix length record

Hi everybody,
In the file adapter receiver, I want to create a fixed length record file .
Each record need to have the same size.
How is it possible, because I have a file which contains variable legnth depending of the lenght of message?
exemple:
<mess>
 <row>1234567</row>
 <row>123456789A</row>
</mess>
give the file
1234567<CR>
123456789A<CR>
<CR> means carriage return
and I want a file like
1234567 <CR>
123456789A<CR>
with the same lenth of record (10 in the example).
Can anyone help me, ,please?
Kind regards.
E. Koralewski

Hi Eric,
Create a value user defined function with one input argument a and name it is inputpad. Then add the following code:
Imports: java.*;
while (a.length()<Integer.parseInt("10"))
 a= a +" " ;
return String;
Here I am assuming your fixed length for the field is 10. If it is more or less then change the number. Now in your mapping do all your logic and then in the final add this like:
input ---> your logic --> inputpad udf --> target.

Reading file into SAP from foreground with record length 255

I am trying to read a text file using GUI_UPLOAD. But, some of the records are more than 255 characters in length. When I try to load them to an internal table, the rest of the characters are getting truncated. Is there any possibility of uploading all the remaining characters also? The maximum length of a record might be 400 characters.

Hi
try to define the field of your internal as char longer than 255 char, if u want to make sure u can use the type string:
TYPES TY_LINE TYPE STRING.
DATA W_LINE TYPE TY_LINE.
DATA T_FILE TYPE TABLE OF TY_LINE.

Output data to txt file with full length of the field as in database

Hi
I have a problem related to output data I ntxt file on server
for eg
CONCATENATE
wa_sagadr_outtab-seqno
wa_sagadr_outtab-bpext
wa_sagadr_outtab-name_org1
wa_sagadr_outtab-country INTO wa_sagadr_text SEPARATED BY ''.
the output is separated by single space irrespective of database length of the field , I want to display all the lenth of the database field eventhough the remaining space is blank ie if a field is 20 char in dtabase and only filled with 6 char the whole 20 char lenth should be displayed in the output file
ouput as below
required format ie space equvalent to as in database lenght
000001       700006               C4 Plant AMD Export Sdn.Bhd.so on.
my format as coming single space in between only
000001 700006 C4 Plant AMD Export Sdn.Bhd
pls suggest

For this maintain an work area with the fields and structure same as the one which you want.
ten populate the work are and write to file.
concatenate will not work.
e.g.
DATA: begin of wa_sagadr_text,
          seqno like wa_sagadr_outtab-seqno,
          bpext like wa_sagadr_outtab-bpext,
          name_org1 like wa_sagadr_outtab-name_org1,
          country like wa_sagadr_outtab-country
          end of wa_sagadr_text,
clear wa_sagadr_text.
wa_sagadr_text-seqno = wa_sagadr_outtab-seqno.
wa_sagadr_text-bpext= wa_sagadr_outtab-bpext.
wa_sagadr_text-name_org1 = wa_sagadr_outtab-name_org1.
wa_sagadr_text-country = wa_sagadr_outtab-country INTO wa_sagadr_text.
transfer wa_sagadr_text to outputfile
or write:/ your fields.

How to create an UTF8 data file with max length fields

We have a legacy application which allows for a transparent text field a maximum length of 30 Bytes.
The DB-Length of the field is 40 Chars.
In old NUC days it was so simple:
TYPES: BEGIN OF t_items,
hwmc(30) TYPE C,
A move, that was it.
Now we have migrated to unicode, use UTF8 for the external data and are puzzeling over how to create an output field with a fixed length of 30 Bytes.
Has somebody an elegant idea?

wyfwong, >> Does the schema which stores a large BLOB column has to create a large tablespace in order to store the column value or the database automatically enlarge the tablespace when a large BLOB column is loaded into the table? <<
The answer to this question would depend on how you defined the tablespace adn datafiles used to store the tablespace objects to begin with: raw partitions verse files, autoextend on or off, etc....
It would seem to me to be foolish not to predefine the tablespace at least large enough to hold the tables and indexes based on their expected near_term data loads. That is, if you know the initial load of data will be 60G then the tablespace should be larger than 60G to start with.

Read two lvm files with different length

I'm trying to read to same graph two different measurements with same starting point, starting point is OK.
But when the shorter file is coming to the end the VI stops with following message:
"Possible reason(s):
LabVIEW: End of file encountered.
=========================
NI-488: Invalid argument or arguments to function call."
How can I come over this and get both measurements into same graph in their full length with same starting point?
PS I have attached the VI file, a short and a long measurement file. Changed the file extension from LVM to TXT

Hi,
Apprently your LabVIEW is set with the option "enable automatic error handling", you can change this in tools >> options block diagram untick the option.
Doing this will only get ride of the dialog when the error occurs but not get read of the error.
So you are reading your files chunk by chunk in your while loop, so at some point you will get to the end of your files, when you do the VI you are using return an error 4 "end of file reached", from here you have different possibilities, if you want to be able to read files that have different length, here is a quick way to ignore the "end of file" error on both files independantly.
Hope this helps
