• Read file, reformat the data, write new file

  Oracle 11g PL/SQL.

  I have a need to read an existing file, reformat the drive and write to a new file format.

  My solution has been to read the file using utl_file and store it in an array of procedure1.  There is a column of data to hold 1000 bytes of data for each line of the file.

  Then in procedure2, read the data through a cursor column, with a certain logic and fill in the fields of a record type object by using the function substr on the data column.  The type of record object has about 80 columns, all TANK types.  The OUT of procedure2 parameter would be the type of record object.

  Then in procedure3, record object would be the parameter, and this recording would be used to write the new line of the file.  The problem I see now is that I can't convert the object record type a TANK in order to write the file.  So that would mean that I have to reference each of the 80 columns once again in procedure 3 and concatenate each for the parameter buffer utl_file.put_file.

  I don't want to assign values for columns of 80 exit more than once because that makes the code very long and detailed, so I thought that I assign values to the time in the record object, then pass the record object to the write file procedure.

  I'm looking for suggestions on a better design, or have I missed some very basic code design?

  Thank you.

  Thanks for all the great suggestions.

  The original file is from a COBOL program.  What I ended up doing was reference and readability, I have defined/filled all fields of provision of COBOL in my program and then concatenated fields during the construction of the output string.  It's a bit verbose, since the 80s fields appear twice, but the code is clear and easy to understand for support purposes.

  Thanks again for all the thoughtful suggestions.

• How can I write snapshot of my data to the file measured every 5 seconds

  Hello

  I try to take a snapshot of my stream once every 5 seconds and write it to a. File LVM. I have problems with the VI "write to a measurement file. The pace at which it writes data to the file seems to be dictated by the 'Samples to Read' parameter in the DAQ assistant. I tried placing the VI 'Write in a file measure' within a business structure and the launch of the structure to deal with a "time up" VI. As a result only in a delay of 5 seconds before the insiders 'Write in a file as' VI. Once the VI 'Write in a file as' is launched, it starts writing at 20 x per second. Is there a way to change it or dictate how fast the exicutes VI 'Write in a file measure'?

  My reason for slowing down the write speed are, 1) reduce space occupied by my data file. (2) reduce the cycles of CPU use and disk access.

  The reason why I can't increase the value of 'Samples to Read' in the DAQ Assistant (to match my requirement to write data), it's that my VI will start to Miss events and triggers.

  I don't know I can't be the only person who needs high-frequency data acquisition and low-frequency writing data on the disk? However, I see a straight road to key in before that.

  The equipment I use is a NI USB DAQ 6008, data acquisition analog voltage to 100 Hz.

  Thanks in advance for your help

  See you soon

• Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM

  System:

  Toshiba Satellite A-75

  WIndows XP Home Edition
  Fully updated with Svc Pk 3
  HITACHI Travelstar hard drive 80 gig

  Nice day

  I'm getting this ' file is missing or damaged:------WINDOWS-SYSTEM32-CONFIG-SYSTEM ' error and Windows does not start in the F8 boot options. When I disable the auto reboot, I get a BSOD 51 registry error, consistent with the file "missing or corrupt" error Surprisingly "Recovery Console" works so I used to run chkdsk. This has not solved the problem, but even once, surprisingly, the utility reported no fixed error. Ok. I do research online (using another computer of course) and check out the many tips that I copy some files in my "c:\windows\repair" folder in the folder 'system '. Before I had time to do that, however, I found an article from Microsoft stating that this should not be done if you have an OEM System... what I'm doing. Apparently, hives system on these OEM installed OS set other passwords that can permanently block you on your records if you use this method. Thanks for the warning. My system restore disc is nothing more than a tool of re-insall OS that will wipe all my data in the process, and this is not desirable. Currently, I see again all my data on the drive by using the "recovery console". I'm ready to thread the needle on this one in the hope of re - access the operating system, although in some limited capacity. Any help would be greatly appreciated.

  When you run chkdsk in RC, did you use the /r switch? This is the key! In other words, this should be the command:

  Chkdsk /r

  (there is a space before the slash)

  Moreover, KB307545 can be run safely on most OEM XP installations. Of course, nothing is guaranteed 100%.

  Before you do this or else, you really must ensure all data is stored safely. One way to do this is to start on a live Linux CD and then copy the files to an external hard drive. Another way is to connect the problem hard drive into a working PC and copy the files in this way. This could be done by the servo drive or with an adapter like this:

• Windows system32\config\system file corrupt / missing

  I have Windows XP Home edition on my Sony Vaio. Cannot start Windows because I get a msg saying following file is damaged or missing windows system32\config\system
  Sony support suggested I start mode F8 and select know last good configuration. I tried and got a msg saying that Windows could not start because the following file is missing or damaged

  Corrupt des/windows system32\config\system missing file? How to fix without losing my data? Support Sony says full recovery of the system, but I'll lose data and sounds very drastic!

  e star,
  For your Windows CD, which would have been provided by the PC manufacturer.  Sometimes they have a partition on the hard disk that contains the recovery software and can be viewed during the start up.  You should check with the manufacturer of PC for more information about the recovery options.  Also if they did not provide a CD sometimes they offer the recovery media for sale.

  The problem here is that something has happened to the ntoskrnl.exe file.  It is difficult to replace just this file because the version that's on a CD may be different for the version that you had on your system.  If replace you it with another that it could potentially cause other problems.

  At this point, you will need to do a repair install or restore clean install\factory.  Mike - Engineer Support Microsoft Answers

• 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.

• DASYLab how to write data to a file every 15 minutes

  Hi all

  I use dasylab and datashuttle/3000 to record data. What I want to do is to write data to a file every 15 minutes. I use the milti-file, which can write data to the file diffenret, but how do I control the timing, as the journal data every 15 minutes automatically.

  The other problem is that I use FFT analysis of the frequency spectrum. How can I determine the value of frequency where the peaks that happens.

  Thank you

  Write less data in the file that you have collected requires the reduction of certain data.

  There are three techniques to consider.

  With an average or an average of block - both reduce the data by using a function of averaging, defined in the module. To accomplish the reduction of data, choose block or RHM mode in the dialog box properties, and then enter the number of samples/data values that you want to reach on average.

  Average - when you reduce the data, you also should reblock data using the block length of the change in the output parameter. For example if you enjoy at 100 samples/second with a block size of 64, the average module configured on average, more than 10 samples will take 10 times longer to fill a block. The initial block represent 0.64 seconds, the output block represent 6.4 seconds at a sampling rate of 10 samples/second. If you change the size of output in one block, the program remains sensitive.

  Average block - average values in a block against each subsequent block, where the average is based position. The first samples are averaged, all second samples are average... etc. The output is a block of data, where each position has been averaged over the previous blocks. This is how you will be an average data FFT or histogram, for example, because the x-axis has been transformed in Hz or bins.

  Second technique - separate module. This allows to reduce the data and the effective sampling rate jumping blocks or samples. For example, to reduce the data in 1000 samples / second to 100 samples per second, configure the module to keep a sample, jumping 9, keep one, jumping 9, etc. If you configure to skip blocks, you will not reduce the sampling frequency, but will reduce the overall amount of data in a single block 9, for example. It is appropriate for the FFT data or histogram, for example, to have the context of the correct data.

  Finally, you can use a relay and a synchronization module module to control. For example, to reduce a sample data every 15 seconds, configure a generator module of TTL pulses for a cycle of 15 seconds of time. Connect it to a Combi trigger module and configure it to trigger on rising and stop the outbreak directly, with a trigger value after 1. The trigger output connects to the X of the relay command input.

  In addition to these techniques, you can change the third technique to allow a variable duration using a combination of other modules.

  Many of these techniques are covered in the help-tutorial-Quickstart, as the data reduction is one of the most frequently asked questions.

  In regards to the FFT... use the module of statistical values in order to obtain the Maximum and the Max Position. The Position of Max will be the value of the frequency associated with the Maximum value. The output of the statistics module is a single sample per block. Look at the different FFT sample installed in the worksheet calculation/examples folder.

• Try to write data to the file, but error 200279

  I have problems when writing data to a file. 10 seconds in the recording process, I get the error 200279. I did some research on the subject, but I am unable to corect my code. I think I want to increase the size of the buffer, but he prefers, I suppose, to read the data more frequently. The way that I save my file is, before starting the VI, I attribute a location and name of the file (e.g. data.csv). The date and time is added at the end of the actual when file the I start to record the data (e.g. data_07-26 - 13_122615.csv). If the file does not exist, it creates a new file, and then adds the data of this file after each iteration of the loop. The reason why I did this way was so I don't have to worry about running out of memory, but apparently my code is wrong.

  

  

  I will include a copy of the faulty section of my code. Any help would be greatly appreciated.

  Thank you.

  Your problem is that the writing on the disk is slow.  It is pretty slow so it causes your DAQ buffer overflow and cause error and loss of data.  What you need to do is to implement a producer/consumer.  This will put the data acquisition and recording on the disc in separate loops.  This will allow data acquisition work at speed, that he needs to deal with incoming samples and writing on disk can run at all what pace, he can.  You send data from data acquisition to the loop of logging using a queue.

  You can also think about changing how you write to the file.  VI is constantly open and close the file, which is a very slow process if you do it inside a loop.

• The additional write custom file VI data feed

  What I'm looking for is a way to combine these two in a log file. Is it possible to add these additional variables in the data from the signal arriving at the writing on a measure VI file? If this isn't the case, ideas on how to merge the data into the file only newspaper would be greatly appreciated!

  
  

• write table 2D data in the file but the file is empty

  Hello

  I tried to write all reading of powermeter data to a file in two ways, I can see the output in the Arrais indicator data but when I write to "File.vi of the worksheet" or write to 'text file', the files are empty.

  Please help me.

  Try to remove the vi "STOP".

  I suspect, it prevents the main vi before the backup occurs.

  As a second point: given that you save data inside a while loop be sure you add the data from the file and not crash each time.

  wire that is a 'real' terminal 'Add file '.

• What is the best method to add data to a file stored on a usb flash drive to avoid too many write cycles?

  Hello

  I'm trying to store an important data on a cRIO sampled stream in the USB flash drive.

  I believe that there are two ways to add data to a file:

  1. open the file outside of the loop, then write to the file loop, then close the file outside the loop.

  Pros; More quickly and efficiently than the opening and closing of files in a loop is resource heavy equipment.

  Disadvantages; If the program fails partially through, all data is lost.

  2. open the file, write to the file and close the file, all in the loop.

  With the advantages and disadvantages as opposed to option 1.

  As my cRIO is finally deployed in a hostile environment and data are valuable and processing speed is not an issue of concern in this project, I'm leaning towards option 2, but after a few basic calculations that I realize that I'll be writing/opening/closing the file of thousands of times and I wanted to know if this will wear out the flash memory?

  My uncertainty is due to not understanding what happens when a file is opened written to and closed.  He writes the new data to new areas of the flash, or it write all data on top?  The latter would cause me problems not too long term!

  Any help gratefully received.

  A big thank you and best regards,

  Ed

  The 'magic' is not in the File Format (PDM vs vs binary text), but in the "life" of the file.  This solution creates a file of 24 hours and maintains a different file for each day.  If the USB "dies", you lose everything you have not backed up somewhere.  If the program dies (or errors), you lose the data for the current day.  You end up with multiple files (which can be a more or less), but we must still make the trade-off between (duration) of the file and the file number opens (which relates to your concern for the longevity of the USB).  By the way, I suspect that a good quality USB key (it's what you mean, right?  Or do you mean a hard drive USB powered?  Comments probably apply both) can predict today to not die on you, everything just because you make a lot of reads/writes (of course, you could get in-a-thousand...).

• Error message on Windows XP, "Windows-Delayed Write failed, windows was unable to save all the data for the file.

  I use windows xp as the operating system. I bought the new 3G huawei data card. While surfing internet, between a pop-up is displayed

  «Windows-delayed write failed, windows was unable to save all data in the file C:\Documents and settings\new\Local Settings\Application Data\Google\Chrome\User Data\Default\Session Storage\004285.log.» The data has been lost. This error can be caused by a failure of your computer hardware.

  After this computer freezes and I have to restart my computer. Please help me how to fix this problem.

  The error basically says that he tried to write something on your hard drive and for some reason that unfinished write operation.  This could indicate a bad sector on your hard disk, damaged disk or a problem with your hardware.

  Whenever a problem involving a disk read or write appears, my first approach is to perform a verify operation of the disc to the hard drive.  Even if this is not your problem, it is a step of good routine maintenance. Run the disk check with the "/ R" or "Repair" option.  Note that the real disk check will be presented at the next reboot, will run until Windows loads completely, cannot be interrupted and can take more than a few hours to run depending on the size of your hard drive, the quantity and type found corruption and other factors.   It is better to perform during the night or when you won't need your computer for several hours.

• Write delay failed unable to save all the data for the file $Mft

  Write caching without a doubt "does apply to external hard drives", but it is usually disabled to prevent to sort the problem you are experiencing.

  I've seen several positions reporting to the same question that you do.  All of these positions were with SATA drives.  Is your Seagate eSATA drive?

  The disc is recognized as an external drive in Device Manager?  In Device Manager, go to the drive properties dialog box and click the policies tab.  An external drive should have two options: "Optimize for quick removal" and "Optimize for performance".  An internal hard drive shows the options as gray (with 'performance' selected), but there should also be a checkbox "Enable disk write cache" under the second option.

  What shows in your policies tab?

  If I understand correctly, "writeback" or "write behind" is implemented by disc material or its pilot.  If the option is not available on the drive properties > policies tab, I would suggest to contact Seagate support.
