  Amina,

  You have two choices. First choice, that's what you do, but your syntax is off. It should be:

  REPLICAT load6
  Sh@docqvoice_db username, PASSWORD sh
  ASSUMETARGETDEFS
  CARD sh.products, sh.products of the TARGET.

  Second choice is to create a view on the source using the link from the target database and map display just as in:

  REPLICAT load6
  Username, PASSWORD sh
  ASSUMETARGETDEFS
  CARD sh.products, sh.view_on_products of the TARGET.

  Good luck

• I have a problem when you try to receive data using the socket connection.

  Hello

  I created a socket connection between a pc (sever, win32) and a blackberry (client) and I have only two questions:

  -When I send a string to the sever I get the unexpected result, I doubt if it's a problem of encoding between platforms.

  -When I try to receive data, (an array of char as a string object), the customer demand freeze (drawing and management of events, so basically the main UI thread), even if I did all the stuff of connection in a separate thread, until I have shut down the server and also no data is received.

  I left the codes below and would assess any response from you.

  C++, win32 console application:

  SOCKET _Socket;

  Thanks for your help.

  You treat on the thread of events.

  You have the following code:

  UiApplication.getUiApplication () .invokeLater (new Runnable() {}

  public void run() {}

  try {

  open_connection();

  .....

  Now invokeLater essentially tells the operating system that the associated executable must be run on the event Thread.  You need start a separate Thread.  Extend this Thread, add your code in the run() method, and then start the Thread with start(). (not run()).  Then you must run the networking of processing on a separate Thread.

  This will cause you problems updating the user interface.  Take a look at this help:

  http://supportforums.BlackBerry.com/T5/Java-development/update-a-screen-on-the-main-event-thread/TA-...

  Printing, this means that invokelater a separate Thread is a common misconception.  I recommend you to look at this:

  http://supportforums.BlackBerry.com/T5/Java-development/what-is-the-event-thread/Ta-p/446865

  In addition, I recommend that you take a look at the socketDemo which must be included as a sample-, otherwise you can find it on github:

  Hi Maury,

  There is no need in step 2 that u mentioned above. I donot find useless a webservice?

  The process will be launched by the CSV file, then using the processing activity, you can put it in the DB.

  There should be no way where you can manually test it by giving an entry. All you can do to test is to put the file in the folder you mentioned when configuring the file adapter.

  You just need to have the composite as below:

  ReadCSVFile---> BPEL--> DB adapter

  And in your BPEL process:

  Recieve--> Transformation activity--> call activity

• How to insert data into the database using smartview

  Hello
  I am trying to insert data into the database using * "Send data" * button on the Ribbon of Essbase.
  My database is empty.
  
  I opened an ad hoc network, it returns * "#missing" * in all cells
  I have modified the cells and provided data in the cells that I want to. Now, I supported on * "Send data" * button.
  It just reloaded the adhoc grid instead of submit data, I rechecked the data through data console Administrative Service are not inserted.
  
  I am following the right way to insert data? If not, could you please suggest me how (Populate) insert default data in the database?

  You go about it the right way, once you have submitted if you réactualisiez then data values should be there, if you POV is against members of dynamic calc and then data not written to the database, you need to check the Member properties of your POV.

• Adjust the data in the database with the variables

  Hello

  For my internship, I have an assignment to read and set a database with the variables. This SQL server 2005 database contains variables of a controller. These are read and write variables. The assignment is to display the read variables and the user can adjust the variables of Scripture. The first part was "easy" because the forum contained a lot of examples of this. The second part is more difficult because the forum contains absolutely no example of this. Can I use LabVIEW 2010 and 2011, and also I downloaded the 30 day trial of the database connection tool. If it's useful, I can recommend my company to buy this package. Playback vi makes use of a UDL (Microsoft data link) connection.

  So you guys my question is: is it possible to adjust the specific variables in a database using LabVIEW? And maybe you can give me a little advice on this topic...

  Thanks in advance!

  Roy

  In SQL, the specific data are always selected with the keyword WHERE. In VI to update there is a link for options, you can for example add a constant 'WHERE id = 1457 and measure > 0.54 ".

  You can ofc. also build this chain through controls, settings and other means.

  If you prefer, you can use the Execute Query (under Advanced tab I think) to which you can send the complete query example "TestTable Update set name ="Zeus"where id > 14 and id.<>

• DDF mount data to the database

  Dear:

  I need to design an application to read the data of the DDF file and mount them in database.

  Could you please let me know how I can design an application to read these DDF files.

  I offered to do the next step:

  1 binary reading the orginal DDF file

  2 convert to ASCII code

  3. Finally, following the DASYLab format to enter data and transfer to the database file.

  Thank you

  There are two ways to do this:

  First of all, just read the data using the DATA module to READ and write again with a DATA WRITE module configured to ASCII. Please see the ASCII options to ensure that the data separator, date/time format and the number of decimal places to your needs.

  Make sure that you configure the DATA module to READ to read NOT in real time. The default is to replay in real-time.

  Second, read the data using the DATA READING module and use the module output of ODBC and an Action to write directly to the database module. This implies relatively slow data and cannot be done at high speed.

• How to get the gif file hosted by using the Http connection?

  Hello

  I have an application that downloads animation gif from a server by using the http connection. Here is the code I use to download the image.

  try {
  
              httpConnection = (HttpConnection) Connector.open(url, Connector.READ_WRITE);            httpConnection.setRequestMethod(HttpConnection.GET);
  
              if (httpConnection.getResponseCode() == HttpConnection.HTTP_OK) {                DataInputStream dS = httpConnection.openDataInputStream();
  
                  byte[] data = new byte[dS.available()];                dS.read(data);
  
                  gifImage = (GIFEncodedImage) EncodedImage.createEncodedImage(data, 0,data.length);
  
              } else {                throw new Exception("ResponseCode:" + httpConnection.getResponseCode());            }        } catch (Exception e) {                        gifImage = null;            e.printStackTrace();        }
  

  the problem with this code is, when the gif file is 1175 bytes above, it does not load the gif.

  example:-If the gif on the server is 1500 bytes, this code retrieves only 1175 bytes.

  I think that the rest of the bytes are sent in a different package. But how to get them.

  can someone please provide a code for buffering the inputstream?

  any help is appreciated.

  Dieye

  Hmm, nobody seems to know how to do, it seems. Here's how I did it.

              httpConnection = (HttpConnection) Connector.open(url, Connector.READ_WRITE);
              httpConnection.setRequestMethod(HttpConnection.GET);
  
              int responseCode = httpConnection.getResponseCode();
              if (responseCode == HttpConnection.HTTP_OK) {
                  inputStream = httpConnection.openInputStream();
                  ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
  
                  byte[] buffer = new byte[256];
                  int len = 0, imageSize = 0;
  
                  while (-1 != (len = inputStream.read(buffer))) {
                      byteArrayOutputStream.write(buffer);
                      imageSize += len;
                  }
  
                  byteArrayOutputStream.flush();
                  byte[] imageData = byteArrayOutputStream.toByteArray();
                  byteArrayOutputStream.close();
  
                  gifImage = (GIFEncodedImage) EncodedImage.createEncodedImage(imageData, 0, imageSize);
  

• How s/n know when and what account perform a function using the database link?

  Dear,

  My application of the CIM team asked DBA to create new function and run it. Function must use the database link for remote database data. So I need to create a new database to their licensing link. Cause we guess we'll experience the performance issue after the user performs this function, or another question and errors may occur. So we want to know when and who use this feature that connects to a remote database through the new database connection in advance. And I also need to know when and which connect to the remote database using this new database link. We have no idea to get this information?  Can anyone recommend how do? Thank you very much.

  Best reqards, Otis.

  Check what business purpose, it will solve.  If the function is so safe, why everyone will use. Only admin people should access.

  All of these additional controls of this kind must be avoided as much as possible to improve the overall performance of the application.

  Still if you need, see the database audit mechanism, specifically designed for this type of activity.

  Kind regards

• Upload data to the database

  Hi all

  I have a problem with my request. I've created a sample application that I can show you my problem. I want my application to download data from database to the data grid - as ´s ok. But when I want toload data from database of the data grid, it doesn´t work - when I click on Update button, in early doesn´t of database connection. I use Wamp Server 2 to communicate with the database.

  I think that there is not problem in my source code (I checked so many examples). I think there is a problem with the Zend Framework - I'll try to explain this problem.

  I found that request not to upload data to the database when the folder structure is - look at photo. It is automatically created service in service folder - in my case Tabulka1Service). But what is confusing is that application downloads data from database without any problem:

  

  Request only download data from database when I move all the items to a folder of service - look at the picture. After that when I click the button it starts to connect to the database and downloads the data correctly.

  

  Why I ask you to help me with this problem?

  Because I think it is very bad practice to move items to the folder of service whenever I created new service - I have to completely reconfigure entire service after that - and his loss of time I think.

  I would be happy for all the help.

  Thank you

  Try

  tabulka1 = dataGrid.selectedItem as valueObjects:Osoba

  But u declare

  Tabulka1 id="tabulka1"/>
  

  your dataGrid consists of a crowd of valueObject:Tabuka1 or valueObject:Osoba?

  Here are the various objects you can not their equal.

• Current version of the data in the database has changed...

  Hi, I have an updated report which hurts...
  
  This is the SQL code for it:
  
  Select
  "ITEM_BOM_LINE_ID,"
  "ITEM_BOM_ID,"
  "ITEM_ID",.
  "ID_PROCESSUS,"
  "SEQ,"
  DECODE (ID_PROCESSUS, NULL, QUANTITY, ") AMOUNT.
  DECODE (ID_processus, NULL, UOM_CODE, ") uom_code,.
  "VOLTAGE_PROBE,"
  'POSITION ',.
  "POS."
  "DESCRIPTION".
  of ' #OWNER # '. " TOFC_ITEM_BOM_LINES ".
  where "ITEM_BOM_ID" =: P20_ITEM_BOM_ID
  
  In that select it the ID_processus or the item_id is defined. Cannot assign at the same time.
  
  The description field is what hurt. When I run the page and try to write something in the description field on a line where ID_processus is defined this error appears:
  
  Internal error in the routine mru: ORA-20001: error in MRU: line = 1, ORA-20001: ORA-20001: current version of the data in the database has changed since the user has launched the process of update. current checksum = "B54E29267EC18630B58818FF4B710D41" element = '925466414031BD2DE082A6F954889340' checksum., update of "trailers". "" TOFC_ITEM_BOM_LINES ""ITEM_BOM_LINE_ID"= value: b1, 'ITEM_BOM_ID' =: b2, 'ITEM_ID' =: b3, 'ID_processus' =: b4,"SEQ"=: b5, 'QUANTITY' =: b6, 'UOM_CODE' =: b7, 'DESCRIPTION' =: b8
  
  It works fine when I write something in the description field on a line where item_id is not null. Also all other fields work perfectly.
  
  Can someone tell me whats wrong?
  
  Thanks :)

  Hello

  After a re-read of your OP, I noticed that
  DECODE (ID_PROCESSUS, NULL, QUANTITY, ") AMOUNT.
  DECODE (ID_processus, NULL, UOM_CODE, ") uom_code,.
  in your query.
  And it breaks when ID_processus is NOT NULL (and ITEM_ID is null), isn't?
  That's because you change (sort of) the QUANTITY and the UOM_CODE when that happens. Your query retrieves different values than those contained in the database (for example "instead of the actual value). And these 'new' values are compared with the values of database and then there is a difference. Where the error.

  But now: how to solve?
  What exactly are you trying to achieve with this construction? Is there a business rule that AMOUNT and UOM_CODE must be blank if ID_processus is not null? To add a constraint validation to your table and just show the values in your table. Or to show or hide a value of the terms of use. Or use another (made) column in your query that is not bound to a database field.

  I hope this helps...
