• Structure of the place, table 2D, several channels

  I do data simultaneously on four-lane acquisition, and I need to store the data acquired from a large table 2D to 16 x 16. To save memory, that I decided to use the structure of the element In Place, I've extended it with four functions of Board Index but I'm struggling with what I put on the right side of the structure.

  It is clear that I wire table 2D to all functions of Index table, row and column addresses are constantly evolving and that I have to use shift registers. But how can I tell the LabVIEW I want to modify the same table on multiple channels and do not change 4 different tables?

  VI is attached.

  Thank you

  In place changes just that, in the same place of memory. The same table that you send is what you will get out, modified, even to the same memory addresses.

  The 16 x 16 is intended to hold all 4 channels, or one for each? In the former, you can simply extend the Board index to 4 entries and you will get 1 output to your shift register.

  In the second case you will need 4-Bay, either in the form of 4 individual tables, add a 3rd dimension to table or do an array of clusters (one for each channel) that contains this little picture of 16 x 16.

  How can I add data file to an existing table on Oracle RAC ASM with no OMF? Thank you!

  Hello

  So I guess you have some files in ASM, see your first existing file structure

  Select file_name

  from dba_data_files;

  and to add to an existing table, the example below (even if you're better sticking with OMFs!)-is that what you are looking for?

• What is the best way to move the data from the app and Server data structures?

  Hi guys,.
  
  I developed my application locally with Apex 4.2 and Oracle 11 g XE on Windows 7. Not far away, it is time to move the application to a server Oracle Apex. I guess that Exim is the way to go app. But what about the APA tables and data (tables/as 'customer' and 'account' created specially for the application)? I've been using a modeling tool, so I can run a DDL script to create the database server data structures. What is the best way to move the application data on the server? Is it possible to move the structures and data in a single process?
  
  Thank you
  Kim

  There is probably another way to get here, but in Developer SQL, on the navigation tree, expand objects until your table, right-click, and then click EXPORT... you will see all the options. It is a tedious process and it sucks IMO, but yes, it works. This is zero especially because 1) it's a table at a time, 2) If your data model is robust and has constraints and sequences and triggers, then you will need to disable all for the insert and we hope you can re-enable constraints, etc. without hitch (good luck, unless you have only a handful of tables)

  I prefer to use the oracle EXP command-line to export an entire schema, then the server target, I use IMP to import the schema. In this way, it is almost true. This makes the dirty life if you develop multiple applications in a single schema, and I felt pain - however - it is much easier to drop the tables and other objects is to create them! (thus, even if the process of EXP/IMP moved more than you wanted to "move".. blow everything you don't want on the target after the fact...)

  You can use method datapump oracle too.

  If not, what can be done, IF you have access to both servers of your instance of SQL developer (or if you can tnsping both already from the command line, you can use SQL * MORE), is to run a script that will identify the objects of your applications apex (usually by the prefix for the names of objects, such as % EBA_PROJ_ etc.) and do all the manual work for you. I've created a script that does just that so that I can pass data from dev to prod servers on a dblink. It is difficult because of the order that must be executed to disable constraints and then turn it back on and of course, more complicated if don't always precede you ALL your "objects demand '... (tables, views, triggers, sequences, functions, procs, indexes, etc.)

• Form of the ADF for data structure with several child records

  Jdev version: 11.1.1.2.0
  
  I have a data structure with a one-to-many parent-child relationship. I give an example of the data structure.
  
  Employee table:
  ----------------------
  EmpId
  EmpName
  Salary
  
  Table Historiqueemploye:
  -------------------------------
  EmpId
  Previous_Employer
  From_Date
  To_Date
  
  
  In the ADF form for entering data for a new employee, I want to give a layout (say, a button "Add row") for the history of the employee's employment. How can we succeed in ADF?
  
  I'm new to ADF. Would be grateful if someone can help me with detailed steps or a link showing such a demonstration.
  
  Thanks in advance.

  Hello

  If you exposed a View for the Historiqueemploye table object, then simply drag this point of view as a form and then drag and drop the create operation (within the structure of the View object in the data control palette) as a button for the new line is created. If you do not always display the historical, add it to an af:popup and start button context menu create or hide the af: panelFormLayt that a form is added by default.

• Data not entered in af:table inside the panelCollection

  Hello
  
  I created a simple page that shows the result of a ViewCriteria. BUT when I click on the search button, data is not loaded in the table instead when I click View-> Show All (or any attribute) of panleCollection while data is loaded inside the table.
  
  I created the table inside panelCollection. I want just the result to display in the table when I click search.
  
  Looks like I'm missing something :-(
  
  Please advice.
  
  Concerning
  Sameer

  OK, I see your problem.

  Here is my solution:
  (1) use an af:query with table to start
  (2) select the table in the window of the structure
  (3) right click and select "Surround with...» "and select af:panelCollection. You can do this directly by hand if you want.
  (4) select the af component: query in the structure window and open the property inspector. You should see that the 'ResultComponentId' in the 'Common' section has a red border. This is because the Table that contains the result of the query is now in a different naming container. Click on the arrow down on the right side and the search for the table that is now inside the panelCollection (this is the same work that I described with the partial trigger) and select it.
  (5) save your work and run the page.

  You now have an af:query with table inside a panelCollection

  Here is the code that results in my test scenario:

• question about 'STRUCTURE to VALIDATE the TABLE ANALYZER' in 9i

  Hello
  I have a 9.2.0.8 database on AIX. After a copy of storage of my produztion datafiles from a site to another, I performed a DBV to ensure that all copies were correct. After that I started my db correctly.
  Now might be a good idea to perform a "ANALYZE TABLE tabname VALIDATE STRUCTURE;" statement on any table of my database to ensure that I don't have a corruption? Are there disadvantages of this operation?

  Hello
  You can "validate" it roughly following the steps:

  Start the instance and open the database.

  see the alert log for possible errors.

  check the status of the data files of dba_data_files
  check the status of all storage spaces
  Check for invalid procedures, functions, or triggers and recompile them.
  Check the statistics and you can collect the again.

  If everything is good, so well done and hope for the best.

• Faster performance? : QueryNew, Structure or SQL temporary table?

  Hi there, hope someone can help me. I created a rather complicated calendar application that needs to loop through each week of a month and a scan for orders for this day there show out them well. Because long-term (LT) orders can extend over several days and weeks, so I group them in a HTML TableRow (TR) throughout the week. So to do this, I have the week prior analysis first, write all data in a QueryNew and then empty results in TRs (I can NOT all just a loop for queries per day, unfortunately, long-term arrested because he had to stay is grouped together). And I have to do the pre-scan to determine what day of the week has the largest amount of long-term arrested and other so I don't know how many slots TR banding to explain (and it is also possible to sort otherwise where orders rubanées display, etc.).
  
  Anyway, just believe me when I say that this pre-scan in a QueryNew is necessary.
  
  The problem I have now is that this page takes 52 seconds to load for some customers who have a LARGE number of long-term orders (say 20-40) which analyze several weeks because the QueryNew takes some time to set up and when I interrogate the QueryNew for the post of enforcement LT TR, he took 47ms by command LT per day (which adds up to nearly 52 seconds with all the others) queries). For some reason, the query of a query seems to take more time than a query to an SQL database.
  
  Then I start thinking that the QueryNew wasn't the way to go? Should I use a structure or a Temp Table in SQL instead? Someone at - it any THOUGHTS? I would appreciate so much! Thank you!!!
  
  BTW, here is a screenshot of part of my this QueryNew CFDUMP, I want to talk. DisplayOrder1 is the day of the month and DisplayOrder2 is the number of TR: http://www.planet-k.com/test/queryforcalendar.cfm

  I think SQL Temp Tables is the most correct approach. I thnk that's the
  more effective.

  Scanning/filtering data in sql tables looks like something from the database
  should do?

  Good luck!

• Several Sources of data in a single logical table

  I'm new to OBIEE and I encountered a problem. I apologize if this information is in the forum somewhere, but I've searched and can't find it.
  
  My situation is that I would have a logical table that contains multiple sources of data, which all have the same columns. I already have the configuration of session variables to differentiate the security of the user through the variable for a specific column and a session variable to another column that determines the association of the user with the data source to which they belong to. This security works well when the data sources are separated in the business model and mapping party, but the question that arises is that the user cannot share reports when data sources are separated in the BM & M.
  
  I slipped and fell on a table in the physical model to the BM & M, I dragged then the second source of data (with the same meta data structure) on the "Sources" folder in the first data source table into the BM & M. on the content tab or each table data source, I've defined as WHERE clause where VALUEOF (NQ_SESSION. ("" SCHOOL session variable ") is my filter in the column and VALUE (NQ_SESSION. ("" GROUP filter ') is my critical data source:
  
  sandbox. ». SANDBOX. OBIEE_CROSS_ENROLLMENTS. HOME_SCHOOL = VALUEOF (NQ_SESSION. ("" SCHOOL ") AND sandbox. » ». SANDBOX. OBIEE_CROSS_ENROLLMENTS. DATA_SOURCE = VALUEOF (NQ_SESSION. "" GROUP")"
  
  Unfortunately that returns the values in the BI responses for the first drag and drop material table in the BM & M layer and not the second drug physical table in the folder 'Sources '. I also tried to create a new logical table and drag two tables in the "Sources" folder without success. I have experimented with the Fragmentation in the tab "Content" of the separate logical tables, checking the "this source must be combined with other sources at this level", which gives me an error in the responses of BI that there is no such thing as a column which has really.
  
  What might be missing? Thank you in advance to those who respond.
  
  Thank you
  
  Kyle

  Do not check the box "this source must be combined with other sources at this level", otherwise, it will always take the first logical table source. If you need to get rid of the error message. Are you sure that you have mapped all the columns on every logical table source?

• How to import photos from iPhoto to the Photos without losing the date structure

  Hey there,

  Today, I realized that not all my photos to the Macintosh iPhotos Photos last year. At this point, I'm missing about 700 photos.

  Is it possible to merge the iPhoto to the existing photo library library while keeping the structure of date? I tried just to drag some photos but they then imported as if they were taken today.

  If possible, I want to keep the date structure so that all the photos that were taken at the same time will remain together.

  Export images from iPhoto to the Finder, and then import them to Photos.

  File-> edit

  This trick of the user

  https://discussions.Apple.com/docs/doc-4921

  a details of the options in the export dialog.

  Ignore the file date.

  There are two types of metadata involved considering the jpeg or other image file.

  One is the data file. That's what shows the Finder. That tells you nothing about the content of the file, just the file itself.

  The problem with the metadata file is that it is easy to change the file is moved from one place to another or exported, by electronic mail, downloaded, etc.

  Photographs have also obtained the Exif and IPTC metadata. The date and time that your camera broken that the photo is saved in the Exif metadata. Without worrying if that said the date of the file, this is the actual time recorded by the camera.

  Applications of photo like iPhoto, Aperture, Lightroom, Picasa, Photoshop etc. get their date and time of the Exif metadata.

  When you export from iPhoto to the new Finder file is created containing your Photo (and its Exif). The file date is reported - exactly - the date of export.

  However, does not change the Date of the Photo.

  The problem is that the Finder doesn't work with Exif.

  Thus, your photo has the correct date and the file does, but these are different things. To perform a sort on the date of the Photo, you will need to use a photo app.

• LabVIEW: Memory data structure or corrupted.

  Hi all

  I know, this is a very simple question, but I couldn't solve it. When I entered a text in hexadecimal control box. I would like this text to be converted to hexadecimal number. I use unflatten string function.

  If I get 8 characters, it does cause some errors. For ex: 1234 5678.

  But if I go, for example, 1234, it causes the following error:

  LabVIEW: Memory data structure or corrupted.

  How can I solve this problem? Thank you and best regards,

  
  

• Corrupted memory or data structure

  I have a .NET application in which to try to determine the VI in a llb file. This is the code:

  I get the error message: LabVIEW: corrupt memory or data structure.

  The LabVIEW.Application reference is correct because the loading and normal execution screw works very well.

• cwimaq vs imaqdx image data structure

  I'm using VB.net (2005) in a simple firewire camera snap and save the application.  I used before CWIMAQ com objects in VB6 without problem (using the WriteImage function).  I made a vast machine vision work in VB6 with the CWIMAQ, so I know that those tools, my trouble is now I'm trying to port to VB.net.

  Currently I can not examples of dotnet component image snap-in to work with the CWIMAQ objects in dotnet.  I tried the examples included with the NI Vision acquisition tools and have had success with the c# examples for imaqdx, not CWIMAQ. The port inherited examples from VB6 to .net, however, there are some usability issues with the structure of COM I'm not smart enough to defeat in .net.

  Here's my problem, and maybe there is a simple solution.  I need to save the image and cannot for the life of find me the imaqdx method that was similar to the cwimaq.writeimage function.  I have the snap-snap-imaqdx working in vb.net, I tried to use the CWIMAQ.writeimage, but of course, I get an error of "implicit conversion" between the CWIMAQ and the data structures imaqdx image. I can get the imaqdx.image as image system.forms.drawing?

  Y at - it an easy way to save an image using the tools of imaqdx in VB.net-similar to the way in which we used CWIMAQ. WriteImage?  Can someone point me to an example or a net which shows?

  Thank you

  James

  Hi James,

  The write functions are methods of the image of the Vision. For example, to save the image in png, you would call

  imageViewer1.Image.WritePngFile

  Our examples of languages of text can be accessed from the Start Menu (programs > National Instruments > Vision > text basic example)

  Hope this helps,
