Interrupt the Visa waiting on event

• VISA waiting on user event

  I have a producer/consumer program that uses an event Structure to manage the keys of the user interface.  I want to be able to use the VISA waiting on the event to read the characters of the RS232 port.  So I created my structure of the event a case for dynamic user events.

  I also create a while loop that has the VISA check and VISA waiting on event inside. I activated the "Serial character" event only.  When I get this event I use the create user Event.VI and the register of events to get an event Refnum

  How the Refnum of the event of this loop in my loop of producer?

  No, this isn't the code. It's a Subvi and a photo. Where you await events VISA? When you generate your user event? Based on the image you call the Initialize_Controller_Communication and remaining in this code to stop buuton is pressed. You start your event structure in the loop from the producer to the end of this VI. So, if you are not hitting the stop button to complete your initializtion it is no wonder that you never see your event executed structure.

  Hi all

  As the example below, I question what is the measure of the value "Waiting" in the section "event wait" AWR report?

  Because "Expected" the value is high, but "Queue time Total (s)" is low. example "SQL * Net message from dblink the" a 30 115 "expected' but 'Queue time Total (s)' lower 'DB file scattered read' w 28 659 'wait '.

  Could you please explain more about the value "waiting"?

  Thank you

  Hi all

  As the example below, I question what is the measure of the value "Waiting" in the section "event wait" AWR report?

  It is simply a... count the number of times where the system had to "WAIT" on the specified event.

  Because "Expected" the value is high, but "Queue time Total (s)" is low. example "SQL * Net message from dblink the" a 30 115 "expected' but 'Queue time Total (s)' lower 'DB file scattered read' w 28 659 'wait '.

  Watch "AVG time-out.    In one case, there are fewer occurrences of the event, but the average wait by event time was higher.

  If I buy 3 burgers and pay $1000 each

  or I buy 500 burgers and pay $1.00 each.

  Why 3 hamburgers cost more than 500 burgers?

  Could you please explain more about the value "waiting"?

  "Waiting" is the number of times that the system had to wait for the named event, during the sampling period.

  "Total wait time" is the total time (measured in seconds) spent waiting on all occurrences of the specified event, during the sampling period.

  "Avg" wait"is the time (expressed in milliseconds) means spent on each occurrence of the specified event, during the sampling period.

  It seems pretty obvious.  You count how many times it happens something (wait), you measure it, time spent doing this something fracture (total wait time) and tells you the total time spent (total wait time) by the number of times it happened (waits) to find out the average time spent on each occurrence of that something.

  Edit:

  I know that maybe it's a little late to come and see this post was several months ago, but I had the same problem.

  I ended up turning off the machine and opening printer and check the ink cartridges (I had seen just to find the part number for a new cartridge).  I found that the blue cover which snaps into place on the ink cartridges was broken not closed completely.  This has caused the printer constantly tries to go into maintenance mode, but it could never align cartridges.  She also told me that there is a paper jam, even when there is no paper in the machine.  I even let the maintenance run all night without success.

  Once the cartridges have been broken in place and the blue cover has been fully guaranteed, the printer worked.

  above compositions of this thread:

• "the db file sequential read" waiting for event slow down an application.

  "the db file sequential read" waiting for event slow down an application.
  
  It is a rather strange problem. There is an update statement that hangs on the wait event 'db file sequential read' and until you restart the database, the query works fine. It happens once a week, usually Monday or after several days of large amount of work.
  
  I checked the processor and is fine, memory is very good, although the SGA and PGA have taken maximum memory. Flow of the disc seems to be ok since each another session on the basis of data looks very good.
  
  I guess that there is a missing configuration to avoid having to restart the database each week.
  
  Any help is greatly appreciated.

  and for small tables, you can try adding for example FULL (your) FULL (wsr)

  It can be rewritten in a different way, but it's the fastest way to try how query will be if you rewrite it. Check the explain plan command if certain partially ordered tables are not joined because you can get the Cartesian join, it seems that it will be ok.

  View query result in the em console.

• Den inst and Mettler balance does not not for the Visa print command

  Hello, I am working at the interface a S-8001 Instrument in Denver and an analytical balances Mettler Toledo PB5001 in the same .vi. Using the subvi VISA I can get two scales to account for their mass in the .vi, but only if I send them constantly of the data (i.e., baud and comm port, etc. are configured correctly). My problem is that ongoing surveys are both unnecessary and are prone to error and the .vi are save only a part (or a zero) in any event given sample. I can confirm in addition to using hyperterminal print control correct for the Denver Instrument balance is "esc + P", and I think that the command of Mettler is a variant of '' IF. '' However, enter either of these commands (and other variations) in the terminal 'chain to write' the visa write .vi does not appear to send the necessary information to the balance to deal with the measure. I spoke with support technique both Metter and DI and after spending time with each other that they were unable to solve the problem... but suggested that perhaps the wonderful world OR maybe get an idea. Forward to your response. Thank you!

  How do you send the esc character? You can just type esc. Hex 1B then you could do a right-click on the control of the chain and select "hexadecimal display. There are other such features a cast and table byte in string that are useful when doing non-ASCII.

• Why "limit maximum instances of this event in the queue" in the dialog box change events?

  Why I "would limit the maximum instances of this event in the queue" in the dialog box change events?

  

  I think that this is new for LV 2014, but I couldn't find an explanation for an instance of good use. A research on OR displays only the 2014 help text, which explains what it does, but not why?

  Does anyone know good arguments to use this option?

  Thanks in advance.

  It is useful for user interface elements that can enqueue actions as quickly as they can be made.

  For example, say it takes takes 1 second to take a picture and save it. The user presses the button "Take a photo", but they do not see a new image file again after a wait of 250 ms (human beings humans can be impatient) so they press twice. Finally, they see a new file image... and then another... and then another... To get rid of this possibility, check this box.

  Or that you have a cursor to adjust some settings. Moving the cursor updates very fast! If the user swipes from 0 to 1 then the program might try to send all the rest as a parameter to your instrument, which takes some time. Instead of sending all of these values, it is probably better if the software can keep up with the cursor and send a value of about 1 at the same time, the cursor said 1. If you do not check this box, the user can be 1, but the unit will continue to receive values from 0.53, 0.54, 0.55...

• What is the cause of the message "Waiting for Service ' Console CVD activity

  I have two related questions.

  basis, I just started centralizing 200 computers ish, all except 2 appears fine, 2 questions, one below and another with VSS errors.  This message is just for the question "in waiting for the Service.

  1. What is the cause of the message "Waiting for Service ' Console CVD activity and is there anywhere that documents these meanings of status.
  2. No idea where I should start troubleshooting the message "Waiting for Service ' I get to the computer below.

  I have a computer with this status which comes to have installed the client and will not be to centralize.  Other computers seem to work properly (centralized).

  The computer is to ping requests, but appears as disconnected in the console.

  I have a new mini iPad 4. I can't delete a game called Float that gives the message waiting. The cross and the oscillation with delete option appear, but it won't when I select Remove. I don't know how it came to be. Any ideas please? Thank you.

  First try a reset to see if it finishes downloading. Press and hold the home and power buttons until the Apple logo appears. Release the two buttons. Wait until the iPad tour starts on its own.

  Check if you can remove the application. If not go into settings > general > use iCloud and storage > storage > storage management. Wait for the list of apps to open. See if the float is on the list. If it is delete it from there.
