• How to calculate the loading time of BDB startup

  Hi all
  
  I understand that Berkeley DB at startup it will read a few pages from the disk in the memory cache, but I don't know the exact number of pages that will load. I think that BDB will load default pages as much as possible in the cache until the cache is full. Is this good?
  
  And how to calculate the cost of time on the loading process? Can it be verified using db_stat?
  
  Thank you very much

• How to calculate the execution time of a SCTL in FPGA VI?

  Hello

  Can someone guide me that how to calculate the execution time of a SCTL for an iteration in the FPGA VI?

  Thank you and best regards,

  Rashid

  Hello r,.

  A SCTL will always run in a beat the clock it has been linked to.  So, if you use a 40 MHz clock, this loop will run in 25 ns.  If the code cannot complete in that, or if it requires two graduations of the watch to do the calculation, your code does not compile, then you have the guarantee that this will always be how long it takes this piece of code to run.

• How to calculate the number of days between dates

  How can I determine the number of days between 2 dates? Say today and 10/07/46
  
  Thanks Bob

  You could do it like this:

  Photoperiod var = 1000 * 60 * 60 24; number of ms in a day

  var today: Date = new Date();

  var every time that: Date = new Date (1946,6,10);

• How to calculate the polynomial graphic adjustment of waveform

  Hi all

  I am new to lab - view so would need a little assistance in one of the problem I have right now.

  My problem is: how to calculate the polynomial graph of waveform data adjustment? I need to convert the waveform to XY graph data, and then use the polynomial vi made integrated to calculate the fitting?

  Detail: My problem is that I have waveform graph, I calculate the vertices and the Valley, but because of the noise, my peaks and Valley detection is sometimes not exact, so to smooth the chart that I must apply the polynomial fit.

  If anyone can help me in this, I'll be very grateful.

  Thanks in advance

  Hi Omar,.

  have you seen the suggestion of Lynn above?

  You already have the values of Y (your table). Now, you need build the table of X as indicated, only to replace the value of dt with your spacing from point to point. Somewhere in your code, you know that the value that you have an x-axis indicated in milliseconds...

  

• How can I calculate the total time in java?

  Hello!
  
  I need to calculate the total time!
  
  For example I start time:
  Format formatter1;
  Date date1 = new Date();
  formatter1 = new SimpleDateFormat("hh:mm:ss");
  Dim startTime = formatter1.format (date1);
  startTime = "14:20:40.
  
  And I have finishing time:
  Format formatter2;
  Date2 date = new Date();
  formatter2 = new SimpleDateFormat("hh:mm:ss");
  String finishTime = formatter2.format (date2);
  finishTime = '08:30:55;
  
  
  
  Also, having calculated manually, I get the total time: '18:10:15.
  
  How can I calculate the total time in java? (Using formatter1 and formatter2 I guess)
  
  What I need is to print 'total 18:10:15 '.
  
  Thank you!

  I did the following, but I think something's wrong here:

  I've defined before: Date date1 = new Date(); Date2 date = new Date();
  And it should be exactly 5 seconds between them.

  I found the delta between date1 and date2:

  Format formatter = new SimpleDateFormat("HH:mm:ss");
  timeInMilliFromStart long = date1.getTime () - date2.getTime ();
  Date date3 = new Date (timeInMilliFromStart);
  String timeInSecFromStart = formatter.format (date3);

  and I still get
  timeInSecFromStart = 02:00:05

  But it should be exactly 00:00:05.

  What is a problem?

  Because, as I said, a Date to measure a moment in time, not a period. So when you have 5000 ms, and you that transform a Date, this means that 5 seconds after the time, which equals 00:00:05.000 01/01/1970 GMT.

  As I said, if you are not currently in GMT, then you must set the DateFormat GMT TZ. Right now, it's to show you the time in your TZ. If you have included the date in your SimpleDateFormat, you would see the 01/01/1970 or 31/12/1969, function that TZ you find.

  Bottom line: you try to use these classes in a sense they are not intended for, and while you can get the results you want for a limited set of entries if you understand how these classes and how to work with it, it is a fragile approach and comes with all sorts of warnings warning.

  Hello

  The page/site seems to load very well at the moment.

  However if want to inspect what could slow down the loading of your page I recommend using 'firebug' and select the 'network' tab to follow every chronology file loading.  Then you can see which file takes more time to load to help make adjustments accordingly.

• How to calculate the time to SELECT

  I want to know how to calculate the time taken by the SELECT query.
  
  For example: I run a select statement in TOAD (oracle version 9i) who takes 40 seconds to run, but in the output window, it displays few records. It says "list 1 of 500 records, more records exist". This table has total 20 million records.
  
  Now my question is: have you my SELECT query took 40 seconds? or it took 40 seconds to SELECT 500 records.
  
  If it took 40 seconds to SELECT 500 records then how to calculate the total amount?
  
  Any help would be much appreciated.

  To avoid the exit which is probably not really need you can make

  begin
    for c in (select * from xy /*your query */)
    loop
      null;
    end loop;
  end;
  /
  

  This gives an estimate of the time to recover all the lines.

• The loading time of a Web page takes about 30 seconds. How can I improve this

  It comes to this page: http://www.barronstudio.nl/hoogstraat-2-bergen-op-zoom.html

  Hello CreativeBarron,

  I checked your site at my end and observed that you used several large images in Muse that contributes to the load time. Please look at the screenshot below.

  By reducing the size of these images, you can certainly reduce the loading time of the site.

  I'm with you.

  > How can I writer this number in the code? Is it 0026 or 26?

  The code expects milliseconds, then 26 seconds would be written as
  this:

  26000

  If he said 01:22 (one minute and 22 seconds), you must write it like this:

  82000

  ... which is 60 seconds for now, 22 seconds
  side, then multiplied by 1,000 to get milliseconds.

• How to calculate the length of the video format (seconds)

  Hello
  
  I use the ActionScript 3.0 CookBook book and it shows how to calculate the length of a video (and also playing the video in progress) in seconds using the property at the time of the NetStream class.
  
  So, for example, the length of my video is 1070 seconds.
  
  But I want to be able to convert a format such as ' 00 (hours): 00 (mins): 00 (dry) ", '1070 seconds' how can I get this?
  
  Any help is appreciated!

  Checkpopint operations which are drivern by the volume of interval and log checkpoint are those that are 'Checkpointer' in the output of ttCkptHistory. Control points can also occur for other reasons, for example when the data store is stopped, when it is loaded in memory and recovery is necessary. These kinds of control point are marked as "Static" and "Subdaemon". You can see three of those in the output.

  The output, it seems you're checkpointing about every 4 minutes. Assuming the target settings (interval 600 seconds, Journal volume of 1 GB) were already in place at the time of these control points has occurred then it seems that all of these were led by the volume of the journal rather than the checkpoint interval (that you generate ~ 1 GB of log about every 4 minutes).

• To build the waveform.vi function how to calculate the value of dt

  Dear all

  Please guide me How to calculate the value of dt according to waveform.vi of construction

  It's all simple arithmetic. The inverse of the sampling frequency power of samples is then the dt or the time between samples the number of samples is not relevant.
