• Reading excel data file in Oracle form data blocks

  Hi all
  
  I want to read the data from the excel file in the data block of the module of the form. There are many resources available that explain how to put the data in oracle forms in the excel sheet, but I can't find a single resource to achieve this functionality. Can someone please help me get around this problem. Any help will be much appreciated.
  
  Thanks in advance

  Bilal,.
  There is little documentation available through My Oracle Support, which shows how to read an Excel file in a form, but you need a support contract with Oracle to access the document (how to read data from an EXCEL worksheet in a form using WebUtil Client_OLE2 [813535.1 ID]).

  I've seen this issue come up in the forum from time to time, so I wrote a small form demo which illustrates playback in Excel in a form. Discover forms: how to read an Excel file in a form. This demonstration uses the WebUtil library, so you must make sure have WebUtil correctly configured in the Forms Designer, as well as on your application server.

  Hope this helps,

• RMAN & read-only data files

  DB: 10.2.0.4 (just upgraded from 8i)
  Win 2008 64-bit operating system
  
  This is the first backup of the 10g database after the upgrade & with RMAN.
  I copied all the backup files to another server to test and try to create a new database.
  
  The backup script was: -.
  run
  {
  backup as compressed backupset database more archivelog delete all entries;
  }
  
  When I run the BACKUP from the LIST, I can see the data files read-only listed with the rest of the files.
  
  On the second test server, I mounted the database & run a restore command.
  run
  {
  allocate channel d1 type disk;
  restore the database;
  }
  
  He restored all the files except those unalterable. So now, I get an error "alter database open resetlogs ' may fail because the RO data files are missing.
  
  I tried to do the restore using RESTORE DATABASE CHECK READONLY, but now I get an error saying: -.
  
  RMAN-00571: ===========================================================

  RMAN-06023: no backup or copy of 7 found to restore
  
  But the BACKUP from the LIST is displayed data readonly files in the list.
  
  How to make this work?

  If you have physical copies of the datafiles made after the Tablespace has been read-only restoring them (using the operating system utilities).

• merger acquisition of data to read input data 2 or several at once

  Hi all

  I'm using or usb-6009 more then 2 incoming signals.

  the problem is that I can't read 2 signals at the same time. 1 my daq assistance will be apeared to be error.

  so, how can I set the .vi (attached) so that he could read 1 more signal since the acquisition of data?

  I also tried to separate daq support but error. I also try to merge the two signals with a different port (a1 and a0)

  can anyone help?

  Thnx for the reply

  Frankly, I went through all the tutorials and looked for answers in the forum and the conclusions I have difficulties to understand the technical language... I have been looking for everywhere labview users and found someone who could guide me carefully... im have desperately need guidance... not to give up hope trying to find the answer, but a sort of feedback that is giving advice that you need to take the driver's seat... FYI... I take the driver's seat... that look like a real Nubian now needs help...

  is there any order step by step so that I could add channels more 1 1 daq help?... I've done it before, but it occurs.

  for example, I want to create channel 1 to read the value of the resistance and channel 2 for playback of tension... but what happened when I create more than 2 channels, it is be will configure this channel only 1 located in the block diagram... both channal will give only data for the value of the resistance.

  Sorry for my broken English.

• Simulation read data file (*.) (DAT) by using the worksheet (file reading eror - zeros)

  Dear OR community,

  IM pretty new in LabVIEW, so I have a few broblems with reading the data.

  I take a screenshot and mark a problem like part - A and part b below:

  

  The description of the goal:

  I do a mathematical simulation, using the old software whitch exporting results as shown in 1... DAT file, as it shown in the picture (Notepad).

  First of all I need not read these data then I need to draw the graph XY.

  Description of the problem:

  I created a LabVIEW program and im using a funciont reading of spreadsheet per section B - but when im trying to read data im getting all zeros...

  so I can't identify my problem... What is the problem?

  I try different file to read its Case_test_working.txt and everything is good with this data but when im trying to read *. DAT file zeros is array...

  I tried to use seperator different symbols, also try to imort data to exel then export to *.scv, *.txt formats, but the performance was the same as that indicated in part-A.

  Whenever I get zeros, but not a results as in *. DAT or another file format exported with the same data.

  Please be respectifull and understand that im still newbie in labview but I think its excellent software of filtering of the analysis of data and calculations, so I want to master this software for my future use.

  Respectfully,.

  I would like to give you an excerpt, but I've not updated this machine yet.  It's a pretty boring delimiter, if you know what's good for you, you start to use commas, tabs or simple spaces (my order of preference).  It is far too easy start add or remove spaces and then you need to use more complex methods to obtain data from worksheet.

• Read large binary files in addition to 1,000 records

  I have a few large binary data files created in Labview which cannot be entirely read in Labview. Normally acquire us data in Labview and analyze in Matlab. But now we need to read them in Labview. The files have a header that tells us very well. Then there is data of 64 channels. There is a piece of data of each channel for each stamp of time for 300 000 locations. The table of data read in is therefore 64 lines by 300 000 columns.

  MATLAB reads these files in their entirety. But Labview will show only the first 1000 columns. After reading the data file my table is only 64 lines per 1000 columns. It seems that is the default maximum table size or the maximum number of records for Binary File.vi reading is somehow limited. I searched and didn't find an answer.

  

  My vi is attached. The data file is too large to post on the forum. If someone can tell me how to post large files, I'll put it up.

  Any help would be greatly appreciated!

  I can't download your data file.  It is blocked by my antivirus because it is suspicious of your file hosting websites.

  You have your program that creates the data file?  See how writing can say more how the data file is packaged.

  Try to set the data type for the last reading a constant I16 rather than an array of 2D I16.  When you read a 2D picture, he expects that size data in row and column to be part of the information, in that it is reading.  If this information is not there, then it will be you end up with an error message you get.

  If the data have been written just as a series of values I16, then row and column sizes will not here.  Then read in as a type of data I16 and you will get a 1 d table as long as necessary.  Then, you would need to remodel in a table 2D of the appropriate dimensions.

• Data in the data file header

  RDBMS version: 10.2.0.4.0, 11.2.0.2
  
  During the backup hot (RMAN and user managed backup), data can be written and read from data files. But its headers are frozen. Then, where will be data for the headers of data stored up to that hot backup is made?

  Why must 'means for the headers of data data' be 'stored' somewhere?

  The header is not updated. Header updates are Checkpoint SCN, LogSequence (which is not visible to us) etc. These updates are applied to the data file when the database tablespace backup is complete. Intermediate of the SCN values need not be "stored". When the ends of backup and a control point is completed, Oracle updates the header with the current SNA Checkpoint.

• Orchestrator read the local data file

  I run my workflow on computer xyz. On this machine, I have several data files that I'd like to read and use this data in the workflow. These files are changed fairly regularly.

  I run the following code and get the following error:

  var myFileReader = new FileReader("c:\\path\file.csv");
  myFileReader.open();
  testrecord = myFileReader.readAll(); //testrecord is a String variable
  myFileReader.close();
  

  Permission denied on the file ' / var/lib/vco/app-server/bin/c:\path\file.csv', was not allowed to read

  This shows that orchestrator is trying to read the file from the device to VCO vs my local computer.

  Is it possible to have the VCO to read a file on my box local xyz? Having this file uploaded to the device to VCO on each change may be a bridge too far.

  I thank very you much for any help.

  The Orchestrator device cannot automatically access your local computer (such as any server). Instead, the files that must be accessed by Orchestrator should be provided in one of the following ways:

  • Use mimeAttachment as an input for the workflow (s) that you need to run and provide the files the workflow runtime, then download the content of the mimeAttachment in your scripts, treat you like
  • Store the files on a network share visible on the server Orchestrator (vRO device (s) would need to mount the disk AND local file system rights allowed according to the Docs vRO file-io - rights.conf)
  • Store the files as a resource on the server Orchestrator items (this option is preferable for a little static files as text from the models, the INF files, etc...)

• Satellite P500/01R reads the data, but cannot write data on CD files

  I recently bought a laptop Satellite P500/01R. I am able to read a data CD, but can't write data on CD files. The CD is read/write.

  Any ideas?

  Hello

  Have you tried different burning software?
  I m using Nero and in my opinion one of the apps better combustion.
  Here, I can choose between CD, DVD, DL or Blueray (only possible if the CD/DVD drive also supports this).

  Have you also checked diffΘrents CDs from different manufacturers?
  You should do this since not all disks are 100% compatible.
  I had several problems with different CD or DVD in most of the cases it was a compatibility issue, I tried TDK and this kind of drive is compatible with my CD/DVD drive
  I m using the standard of R.

• How to implement the reading of data from a matte file on a cRIO?

  Hi all!

  I'm still not sure, it is plausible, but I'll ask rather before you begin complicating. So far, I found no useful information on reading in the data to a device of RT from a file (type of a simulation test - data is simulated).

  I have the MatLab plugin that allows the storage of data read a MAT file, which has a number of columns that represent the different signals and lines representing the samples at a time (depending on the time of the sample - sample every time has its own line of signal data).

  I have no idea how to implement this at cRIO.

  The idea is:

  I have some algorithms running on the controller of RIO in a timed loop. As the entries of these algorithms I need to access each of the values of columns in the row, which is the time of the sample (sort of a time series - without written actual times).

  I am fairly new to RT and LV development, so any help would be appreciated.

  Thank you

  Luka

  Dear Luka!

  I think the reading of all the samples in a single channel is exactly what you need here, because reading the files may take some time and is not deterministic, so it is best to read all the data in memory (or if this is not feasible due to problems of size, fairly large pieces may be sufficient). The table read can be provided and then in the loop simulating outings, something like this:

  

  I used here separate channels so it's more graphic, but you can build all the channels in a 2D array and array index corresponding to the samples fom 1 who. You can also use for loops with indexing as tunnels are setup and then you won't need the index functions and the number of iterations is also set automatically, but you have to take care of synchronization settings.

• Add data to the input csv file

  I'm using a csv file as my data entry for a test. Test data are simply saved in a table. How can I add these data from table to the CSV of origin, as an additional column, once you click on the stop button?

  To add a new column, the only way is to read the entire file, convert a 2D array, add the new column and then write the new 2D array in file. This is a limitation of the windows way written files and has nothing to do with LabVIEW.
