Problem Regarding Duration of Test(Elapsed timer)

Hi All,
I am doing positive negative pressure cycle test in which positive negative cycle going on continously & shown on graph.
I have to show duration of test as cycle starts in HH/MM/SS format continously as test is going on upto a fixed no. of cycles.
I have taken elapsed time express vi in my main loop for showing this. As in my program there are various loops one inside another in main loop.
So my problem is this timer is not showing elapsed time in continous updating mode but it shows elapsed time when i press exit button. I know why it is not showing because it is going into another loop in my main loop.
Can anybody suggest me how to show my duration of test in continous updating mode?
Thanks & Regards,
Vipin Ahuja

A slightly more robust elapsed test timer than the previously linked FGV was presented as a small part of the community nugget series on application development. Once initiallized with a refnum to the GUI's elapsed time indicator, this Resouce Module can be called from anywhere or everywhere in the application to update the GUI.
A modification of the vi was also presented HERE as a GUI Element Resource Module, GERM, in a nugget I co-authored with Richard Sorrellis (AKA Broken Arrow)

Data Blocks and the Elapsed Time

Hi,
I have created 3 tables with one column only. As an example Table 1 below:
SQL> create table T8k( x char(2000));
So 3 tables are created in this way i.e. T8k,T16K and T4K
T8 = in the default database tablespace of 8k (11g v11.1.0.6.0 - Production) (O.S=Windows).
T16 = I created in a Tablespace with Blocksize 16k.
T4K = I created in a Tablespace with Blocksize 4k. In the same Instance.
Each table has 290,000 rows and all the 3 tables have equal size of 555MB (2006(rowsize with overhead) * 290,000/1024/1024 = 555MB) to test Elapsed Time (set timing on).
As these 3 tables are created under different block sizes so the allocated no. of data blocks are different as below:
T8K = 97177 BLOCKS= 00:41:20.21 (Elapsed Time)
T16K=41639 BLOCKS= 00:44:11.59
BT4K=293656 BLOCKS=00:37:29.06
Please note the difference. First table i.e. 8k block size, allocated blocks are 97177 and taking around 41 mins. Third table i.e. BT4K (in a 4k block size tablespace), allocated blocks(293656 ) are almost 3 times bigger, taking around 37 mins to execute the query. I mean the difference is only 4 mins hardly and blocks difference is 3 times.
In case of any doubt, I've created these tables bigger than the memory used for my db(memory_max_size 408M) i.e. 555 MB that If Blocks are already in cache then reading the blocks and counting the rows will nearly be the same regardless of the block sizes or the number of blocks.
Need solid suggestions and if possilble, links also which has some serious discussions regarding my issue.
Bundle of thanks.
Best Regards,

Because I was not completely satisfied with the things last time. It doesn't seem so simple to me as people said
I thought may some guru have a look today, not just to point out that i have created it again.
And I have compact my question to avoid confusion.

Elapsed timer

I am new to LabView and have an elapsed timer .vi that is not counting down. I am using this to control a heaters run time, and I want it to show the time I started the test and the elapsed time of the test, with the added control of adding or removing hours of test. I have recently upgraded to 8.6 from 8.5 and that is when the .vi stopped working correctly. Any suggestions would be great.

Resetting elapsed timer

Hello everyone,
I am working on a temperature application. I am taking thermocouple reading from a FP-TC-120 device.
I want the thermocouple reading to stay within 1 degree accuracy range, say for 10 minutes. To do that I have written the attached VI. (Required temperature value and time target are inputs to the VI.) The problem is I want the elapsed time to be reset when the temperature value falls out of range. In the application I have written it reset no matter what the thermocouple reading is. Does the problem have something to do with the case structure? (I tried to use while loop but I had trouble with getting the thermocouple reading inside of the loop)
Thanks
Deniz

The way you have it, the timer resets whenever the front panel boolean is true. You have absolutely no relationship to the thermocouple reading being in range or not. A simple fix is shown below.

Youtube videos won't show duration time and elapsed time!

Hello all.
I have a problem with YouTube on iOS 5.1.1
Whenever I play a video from YouTube in safari there is no duration time or elapsed time dispayed .
However restoring from an iCloud backup fixed the problem.
A few days later this problem occurred again. So I searched iCloud for any safari related elements, I found com.apple.webviewservice
I google it but I couldn't find any relations with playing videos;(
Then I discovered videos from other web page play without any problems so the problem only occurs only when i play YouTube videos from safari
Also I think this is a problem with the video player not safari because I used another browser (mercury) and tried to watch a video on YouTube, same problem. So I hope any of you have enough knowledge unlike me to help me solve this problem.

Thanks for your support lllaass.
The YouTube app works just fine.
I just want to know what causes the problem.
Or is it a YouTube bug after all?

The elapsed time problem !!

Hi ! am working on a program that calculates the elapsed time (for the needle of the gauge to reach a value which is previousely defined) also the elapsed time while the needle is maintained at the same value, which means there are two time counters, the first one stops when i reach the value and the second one stops when i leave it.
everything works except that when i reach the value the needle gets stuck there and can't be moved so the second timer doesn't stop.
regards...

AGI = attitude gyro indicator ( it indicates the degree of turn of the plane)
i hope u understood what's it all about
thank you
What he's trying to say is he doesn't understand why the time delay is hanging off the end of the while loop like that. Since it won't execute until after the first while loop is complete, what does it do? If you're hoping it will induce a wait in between the two while loops, it might accidentally work that way, but since the second while loop and the time delay are running in aprallel, there's no way to determine which will happen first.
BTW - if you already know what the code does, what, exactly, is your question? How does what it is doing differ from what it should be doing?

Problems implementing the elapsed time express vi into my vi

I am trying to implement the Elapsed Time Express VI into my VI so that my VI runs for a specified amount of time. I currently have the express VI working, but now that I have implemented it into my VI, my graphing functions do not work. If anyone has any suggestions, I would greatly appreciate your help. I have attached my VI for reference.

Inj&Sam_C348_C_wrt_File_and_Timed.vi ‏405 KB

The way you have your VI configured, the outer while loop will only run once. It will run, but will not be able to continue until the inner loop has completed. The inner loop will continue to acquire data until the desired time has passed. A this time a true will be written to the stop terminal on the inner loop, and then passed to the stop terminal on the outer while loop, stopping it when it has only run through one iteration. I'm not sure what you are trying to do, but my guess is that you want your second while loop to be outside of the first one. You can then stop them both by using a local variable or some synchronization mechanism.

Problems with my Mobo - Hangs at "Testing Real Time Clock" - Whats up?

Specs:
MSI K7 Master - MS-6341
AthlonXP 1800+
512 PC2100 DDR
40 gig Maxtor or Seagate 7200rpm, 2mb cache - tried both
Pine 56x CD Rom
eVGA GeforceFX 5200
Generic 420watt PS AND Antec TruePower 430 watt PS - same results
Alright, I can access the BIOS, etc. but after the first startup screen (with ram, processor type, IDE config, etc.) the screen just has a underscore blinking at the top left...and the error system says Testing Real Time Clock - Ive basically narrowed it down to the IDE connectors since I can unplug the hard drives and it gets past that section and asks for a boot drive - anyone have similar problems? I know he board is old but its for the family and Im stuck right now and I got some anxious members of my family wanting to know whats up with the system - any help will be appreciated...
It should be noted that I was able to install/run Windows for a couple of days - then I got stability problems which was from the BIOS overclocking my ram past spec but I fixed that and Windows was fine but now I cant boot back up and it cant be virus or bad hard drive because Ive tried more than one - some people who also have this problem can sometimes boot to their OS but its usually not the case...thanks again for the suggestions..
Things Ive Tried:
Replaced the CMOS battery
Cleared CMOS
Change IDE channels
Tried just the hard drive
Removed jumper from hard drive
Cleared CMOS
Reseated the ram
Reseated Video card
Cleared CMOS
If someone can find a working solution for this, Ill give them something in return - like some DVDs or cash or something, I really need some help..
- Adam/vicks

No problems with the mobo physically - I got it new from a trusted guy on some forums I goto (anandtech) new from an RMA - still sealed...
I have it running....again....it doesnt like that 1st IDE channel for some reason - Ive restarted/rebooted a few times and nothing has happened so hopefully its fixed but still not cool - Im almost 100% sure it will happen again...

How to get elapsed time in case struture?

I'm trying to get Elapsed Time VI to work but couldn't figure out how to use it properly.
I have a subVI with state machine structure to decode data stream from serial port.
State1 uses VISA read to read a byte and check if it is the Start of Frame. If TRUE, goes to State2. If FALSE, loop back to State1 and try again.
If the State1 keeps getting FALSE for certain time (e.g. 5 seconds), stop the subVI and insert custom error code.
So I have to calculate the elapsed time since State1 starts to be FALSE and keeps to be FALSE.
I tried to use Elapsed Time VI but have problem of understanding it well.
Is there any other better solution than using Elapsed Time VI? Also, how long is the execution time of Elapsed Time VI?
Any suggestion will be very much appreciated.

Hi,
The Boolean output (Time Elapsed) in Elapse Time VI should give True when time got elapsed.
Else we can simulate using "Tick Count (ms)", which counts the ticks in milisecond. You can move on to state 2 when count reaches to reauired duration.
We can give you better idea if you post the code VI.

Calculate elapsed time with VBS/PowerShell

I'm trying to calculate MDT task sequence execution time. What could be the best method for this? It can be PowerShell or VBS code.
Plan is to execute a script at the beginning of a task sequence that stores a start time in variable and at the end of task sequence execute another script that reads that start time from variable and calculates total time taken and saves it to another variable.
I have tried few VB scripts but I have had some odd results some times with them. We are using 24 hour clock and it might have caused some problems for my previous scripts.

I think you can enable monitoring and then validate from a console the elapsed time. It's a slow morning so I also wrote something that would work in powershell for fun -
param($start, $stop)
$file = $(get-date -f mmddyyyy) + '_timer.log'
$filepath = "$env:temp\$file"
function Start-Time {
if(test-path $filepath){
Remove-Item -path $filepath -force
else{
New-Item -ItemType File -Path $filepath
function Calculate-Time {
if(!(Test-Path $filepath)){
Write-Error "Calculate-Time: ERROR - Timer file was not found at path $filepath. Please validate you are running this script with the -start parameter before running with the -finish parameter."
else{
$fileinfo = gci $filepath
$stime = $fileinfo.CreationTime
$etime = (Get-Date)
$time = New-TimeSpan -start $stime -end $etime
return "Time from creation of file to finish is $time."
function Main{
if($start){
Start-Time | Out-Null
if($stop){
Calculate-Time | Out-Null
else{
return "Main: You must provide a parameter to use this tool. Parameters are -start to start the timer or -stop to end the timer and calculate time elapsed."
Main
You can modify filepath at the top to set where it saves the file. What it does is creates a file in the environment temp directory and then uses that file creation time against current date/time to give you a duration. Parameter -start creates
the file starting the timer and parameter -stop finds that file and calculates the difference in time between creation and current time. Either way I needed to get some powershell practice and maybe this will help you.

How to use elapsed time function with state machine in Lab VIEW

Hello
I've been trying to use state machine with elapsed time function in order to sequentially start and stop my code. The arrangement is to start the code for 1 minute then stop for 5 minutes. I've attached the code, the problem is when I place the elapsed time function out of the while loop it doesn't work, on the other hand when I place it inside the loop it does work but it doesn't give the true signal to move to the next state.
Could you please have a look to my code and help me to solve this issue.

OK..I modded the example to stop after 2 cycles. Also recommend taking the free online LabVIEW tutorials.
run vi. case statement goes to "initialize", shift registers are initialized to their constants. goto "wait"
"start"= false, stay in current state. If true, transition to "1 min" case
reset elapsed timer with True from shift register(counter starts at zero)."time has elapsed"=false, stay in current state(1 min). If true, goto "5min" case
reset elapsed timer with True from shift register of previous case(counter starts at zero)."time has elapsed"=false, stay in current state(5 min). If true, goto "1min" case. Also, bool crossing is looking for "true-false" from "5 min" compare function to add cycle count.
Once cycle count reaches 2, stop while loop....

Direct Path Read waits are not showing in Elapsed time

Hi,
I'm having a question regarding interpretation of a SQL trace file. I'm on Oracle 11.2.0.1 HP/UX 64 bit.
Following is only the overall result of the trace (it is quite big).
My question is about the Direct Path Read waits which are totallizing 268s of wait but are not showing in the fetch elapsed time (49.58s) and are not showing anywhere in the trace except in the overall result.
I do not understand why it is not part of the Elapsed time...
For info, the trace is for the specific session that was performing all the required queries to display an online report. The database is accessed by the Java application using Hybernate.
The trace was obtained by the following SQL:
exec sys.dbms_monitor.serv_mod_act_trace_enable(service_name=>'SYS$USERS',waits=>true,binds=>true);Then I query the sessions to find the one created by the application.

I suggest you try the following to narrow down things:
1. Open the RAW trace file and check the cursor numbers of the "direct path reads" - check if you can find any references for those cursor numbers manually. The cursor numbers are those numbers behind the WAIT #<xx>, and you can check if you find any other entry unequal to WAIT #<xx> with the same #<xx>, for example EXEC #<xx> or FETCH #<xx>
A short primer on how to interpret the raw trace file can also be found in MOS document 39817.1
2. Run the RAW trace file through alternative free trace file analyzers like SQLDeveloper (yes it can process raw trace files), OraSRP or Christian Antognini's TVD$XTAT. If you have My Oracle Support access you can also try Oracle's own extended Trace Analyzer (TRCA / TRCANLZR). See MOS Note 224270.1
Check if these tools tell you more about your specific wait event and oddities with the trace file in general.

Please find the below detail 17th day my process are very slow as compare to 18th

Not only queries are different but also the number of blocks read by top 10 queries are much higher on 17th than 18th.
The other big difference is the average read time on two days

You wrote with different execution plan, I think, you saw plans. It is very difficult, you get old plan.
I think Execution plans is not changed in different days, if you not added index or ...
What say ADDM report about this script?
As you know, It is normally, different Elapsed Time for same statement in different day.
It is depend your database workload.
It think you must use SQL Access and SQl Tuning advisor for this script.
You can get solution for slow running problem.

File adapter - Write - Elapsed Time based batching not working.

We are creating an asynchronous BPEL process that creates a file every 2 mins with the messages the BPEL process received in the last 2 minutes. We are using a file adapter with only "elapsed time" set to 2 minutes (Number of Messages and File size disabled) . If we deploy this into BPEL console and use bpel console's stress test feature, it doesnt create any file at all. If we use a file adapter based on Number of messages, it works fine. Can any one of you suggest what could be the problem ?

Unfortunately, this is documented bahaviour (solution/workaround anyone?!):
Elapsed Time Exceeds:
Specify a time which, when exceeded, causes a new outgoing file to be created.
Note:
The Elapsed Time Exceeds batching criteria is evaluated and a new outgoing file is created, only when an invocation happens.
For example, if you specify that elapsed time exceeds 15 seconds, then the first message that is received is not written out, even after 15 seconds, as batching conditions are not valid. If a second message is received, then batching conditions become valid for the first one, and an output file is created when the elapsed time exceeds 15 seconds.
