• What is the best way to backup of virtual machines on a standalone ESX with the data store local

  Hello

  I want to save the virtual machines on a host ESX autonomous. and all of these virtual machines is the local data store.  What is the best way to save these virtual machines in this situation?

  And probably we don't provision VTL on the local data center, so it is possible to use VCB to backup? And VCB is a good choice compared to the traditional method that installs the backup client in each virtual machine?   Because I think that in this situation with the data store local, it cannot not reduced the load on ESX hosts and network overhead can be avoided.

  Thank you!

  LAN

  > 1. VCB usable remote tape library? I mean it's not local library and uses the tape library to another network data center.

  VCB is completely unrelated to the tape library, it is a framework, not a backup solution. If your standard backup software can work with the remote tape library you can try it to ungrateful with VCB.

  > 2. what the difference bwteen hot - added NBD and modes if there is that an ESX host with store data local and want to use a virtual machine like VCB proxy? I think that they are the same: the VCB proxy read data through the I/O of the ESX host stack in this situation.

  NBD works on network and the backup traffic goes through the service console connection. Hot add uses special machine for assistance to connect vmdk to and uses of e/s disk stack instead of e/s network.

  > 3. Veeam Backup is free software?

  No, it isn't.

• Need to get Max Value day in a table with hourly data of SQL

  I have a table "tmp" with these columns:
  
  ID, date, time, value
  
  I want to get the 'time' when 'value' max is reached in each 'day '.
  
  the query:
  
  "SELECT id, day, hour, max (value) from group tmp by id, date, time"
  does not return the desired lines.
  
  You have an idea to get what I want?

  Maybe this:

  with tmp as
  ( select 1 id, trunc(sysdate) day, 10 hour, 100 value from dual union all
    select 2 id, trunc(sysdate) day, 11 hour, 110 value from dual union all
    select 3 id, trunc(sysdate) day, 12 hour, 120 value from dual union all
    select 4 id, trunc(sysdate) day, 13 hour, 130 value from dual union all
    select 5 id, trunc(sysdate-1) day, 10 hour, 100 value from dual union all
    select 6 id, trunc(sysdate-1) day, 11 hour, 90 value from dual union all
    select 7 id, trunc(sysdate-1) day, 12 hour, 150 value from dual union all
    select 8 id, trunc(sysdate-1) day, 13 hour, 100 value from dual )
  Select ID, Day, Hour, Value
  From Tmp
  Where (Day, Value) IN (
  Select Day, Max(Value)
  From Tmp
  Group by Day)
  

  Results:

          ID DAY             HOUR      VALUE
  ---------- --------- ---------- ----------
           7 08-DEC-08         12        150
           4 09-DEC-08         13        130

• Best way to generate a PWM for a stint with LabView2010 and a laptop

  Hello

  as mentioned in the title, I'm looking for the best way to generate a PWM signal to a relay. I want to use a laptop computer and the LabView2010 for she. I have read through several topics, but after a time that he just got more confused. For example the NI USB-6008 OEM case seems to be a solutiion at low prices, but I don't know if I can use for the generation of PWM signals like this thread says is not possible:

  http://forums.NI.com/T5/Multifunction-DAQ/using-PWM-on-NI-6008/m-p/231860/highlight/true#M13339

  But then again this thread right here makes it seem as if it was doable:

  http://forums.NI.com/T5/Digital-I-O/generating-a-PWM-using-USB-6008/m-p/421654/highlight/true#M5527

  Once again in abbreviated form.

  What I need:

  -the best way to generate a PWM signal to control a relay

  What I have so far:

  -LabView2010

  -Laptop

  If possible, it would be good to have two channels for two separate signals, but it is more low importance right now.

  Hey Kambra,.

  The first thread you mention is correct, you can't make output PWM in any deterministic mode with a 6008. The 6008 is strictly software timed, which means that each digital writing that is done in the unit must go through the operating system and down to the device. And there is a lot of jitter of the involved BONE. The second article you mention says the same thing. They emphasized that they could reduce the jitter of some, but still can not remove it entirely. In the second thread, they mention using a M-series USB device do output PWM deterministic (timed material).

  The compromise really down to your application and its requirements. If your application to control the relay requires no determinism, then you can use the 6008. If you need precise control over the relay, try the USB M series.

• Best way to generate signals of activation (square wave) with my 9401 on my 9022?

  Hi, I tried seriously over the past two days to find the best way to do it. I am trying to generate a very precise square wave, controlling the duty cycle and frequency, with the OID on the 9401 in testbed cRIO 9022.

  I have a VI that is theoretically able to do this, but whenever I try to go above 5 Hz or more, duty cycle and frequency becomes inaccurate (I have watch on an oscilloscope), various a lot too for my needs. I have a feeling that this is caused by my addiction on the calendar software controlled, with errors at the time (of the ms order) accumulate as they get processed and the signal is sent. I have attached a piece of code that illustrates the basic idea of what my VI have in them.

  I have avoided the square wave generators integrated because I could never work to satisfaction, but I can work with them so that will solve my problems. Selection structures and cases prevent the user to exaggerate their inputs. Unwaited so the loop was just to test.

  I'm running the 9022 as target in real time, but also tried to run in the FPGA and I was able to produce much more accurate signals using FPGA VI square wave, displaying a Boolean variable, but I couldn't see the best way to get double precision variables to work with everything (and I want more precision than variables FXP enabled clock 40 MHz).

  I feel there is just a mistake in my approach here. I've seen other discussions where people throw around using meters to edge of the test bench to produce a square wave, and I see the example screws as Gen dig pulse - continuous Train, I'm not sure if initially these screws DAQmx for my situation (eg. How to identify my counters, because they are clearly not Dev1/ctr0 by default in these examples)

  Thank you

  This implies the series VI void on the host of the RT, and not on the FPGA target.  So, you also need nodes in the Palette of the FPGA Interface to send PWM fixed Point RT frequency to the FPGA.  The complete solution of frequency may resemble the following.  It is common for FPGA programmers to build a collection of thesesub screw, that make up the API for hardware.

  

  Note that 40 MHz is hard-coded.  For increased flexibility, consider making the FPGA clock rate an entry to the Subvi with a default value of 40 MHz.

  You're right - no page element need! It took me a little bit, but I figured out how to get what I need from your example. The CSS that I use also includes: height of the line, font-size, border and width. I had serious performance problems until I removed the title of column sorting (unchecked all boxes). I added .csv and .pdf links, but they do not have the inline-block formatting so were of no use.

  Of course I learned a lot about the functioning of the reports and models. Thanks for sharing this info Paul - I appreciate it greatly.

• Best way to generate dynamic html in apex

  Hi all
  I need to create a complex page as html with tables in tables, ajax and a very large number of elements (text fields).
  Would like to have your opinion to know what the best solution to create this page. The HTML code in PL / SQL, it is difficult to manage in the future. There is another way to generate code HTML, without being inside PL / SQL?

  Hi 819517,

  You should be able to get your desired using regions and sub-regions effect.
  As you create your own custom for both templates.

  You can find issues with more than 50 fields on your form.
  You can work around this by re using domain names (as in a form of multi line).

  If you submit several hundred fields, you will need to look at settings for modplsql in apache (if you use it) because the maximum number of form fields is a parameter in the conf file.

• Best way to generate the software clock for USB-6501 of Measurement Studio for c# VS2008

  Hi all

  I wonder if there is a better way to generate a clock software for USB-6501 of Measurement Studio for VS2008 in C Sharp?

  I have developed a clock using C Sharp "Thread.Sleep (msecPauseTime)"; and statements to switch digital output high and low. There are a few things I noticed in creating a software clock in this way:

  1. The smallest delay by the Thread.Sleep command time is 1 millisecond (which means higher clock period is 2 msec-500 Hz, not holding not ball account no. 2 below).
  2. Sometimes the delay I see on an oscilloscope is considerably longer than the delay that I specified in the sleep command.

  In my application, I create signals (a clock, a latch enable and data series) to control what an attenuator step through the USB-6501 RF connected to a USB 2.0 on my computer. This particular step RF attenuator can accept clocks with frequencies up to 10 MHz, so I would like to generate a software clock (without having to connect to an external clock to a line of input on the USB-6501) which is closest to this maximum frequency, and I think that the USB2.0 line could handle clock speeds over 500 Hz. Also, I would like to know why the delays that I see on the scope are sometimes longer than the time specified by the Thread.Sleep command. Is it caused by the suspension of the execution of my program processor for something else, as I suspect? Of course, this isn't a big deal, because it does not affect the time as my serial data and pieces change compared to my clock. However, I would like to know why it does this.

  I appreciate your help.

  Thank you

  Jonathan,

  Since the USB-6501 DIO is software programmed, you are at the mercy of the planning of the operating system and won't be able to work reliably with an external clock in the software.

  You can try to set the priority of your thread 'generation of clock' to improve performance, however, because Windows is not a deterministic operating system, there are still no guarantees.  Operating systems are not required to honor the priority of threads.  You can find examples and information on the definition of the priorities of the threads in c# here:

  Realize that Oracle is that I/O block-level.
  As a general rule, any LINE is a single block.
  Realize that is 1 column "count (*)" is correct, then all the columns in the same row are correct.
  This obsessive compulsion to count each COLUMN in each LINE borders on real PARANOIA!
