Start Asynchronous Call available on Real-Time or not?

If I work on code on an RT target the new Start Asyncronous Call nodes do not show up on the Application Control Palette.
However, LabVIEW does not complain if I trick it to run such a node on RT by adding it while editing it for a Windows target...So, is the asyncronous call supported on RT, or not? Well, it does not seem to behave the way you would expect it to..as far as I've ben able to establish so far, but should it? Will it be fully supported (show up on the palette etc.) later?
MTO

I can't comment on whether Asynchronous Call is officially supported on RT in LV 2012 (because I don't know the answer). However, I've used it extensively on RT, and I haven't experienced any problems. Keep in mind that dynamically launching background VIs is going to introduce jitter into your RT system, but that is to be expected.

Start Asynchronous Call Reentrant

I've experimented with the new LV 2011 "Start Asynchronous Call" method on reentrant VIs. I am able to instantiate multiple clones of the VI, but the input data is not propagated to the clone VI. I have tried a few different 'options' flags on "Open VI Reference."
Has anyone else observed this behavior?

Hello Jonathan,
This is Andrew Brown, an Applications Engineer from National Instruments. I will be happy to work with you to get the Start Asynchronous Call to recognize your inputs.
After examining your provided code and creating an example myself, I found one issue with your code. The only flag you should need to use for Asynchronous Call and Collect is x100. That is based off the Open VI Reference and Asynchronously Calling a VI and Collecting the Results documents located within LabVIEW 2011 Help. If you were going to pass in multiple flags, you would want to use the OR operator ( v ) rather than the AND operator ( ^ ).
I attached the example code provided by LabVIEW 2011 within the "Asynch Call and Collect.zip" file.
Based off that code, I wrote my own example that asynchronously calls a subVI multiple times with different inputs. The code for my example is attached as "Multiple Asynch Calls - Diff Inputs.zip"
Please let me know if you are still having issues after working with these examples. Thanks, and have a great day!

Real-Time does not show up as an add-in under NI Max after installing

We are trying to re-install Labview 7.1 Real-Time on a Windows 2K
PC. I insert the Real-Time disk and it completes
installation. After a Reboot, I check under
Softaware/LabView/Addins and it does not show up. It also does
not show up as a target option when I start labview. It worked
before applying the latest RIO patch. After the patch, we
uninstalled all the Real-Time stuff via the Control Panel/National
Instruments Uninstall (apparently, the uninstall from the RT CD does
not actually uninstall anything) We rebooted a directed after
uninstalling. Then we reinstalled RT, rebooted, and nothing shows
up for it. It seems like something is screwed up in the registry
or something. Can anyone help!!!!
Thanks,
Chris

It may be best to clean your registry after uninstalling everything.
This is a relatively extreme step, but after this you should be able to
install (first LabVIEW, then any DAQ, then any add-ons and toolkits)
and see everything in the right place.
After uninstalling:
Remove the following registry components from the Windows Registry:
HKEY_CURRENT_USER\Software\National Instruments Delete the entire tree!
HKEY_LOCAL_MACHINE\Software\National Instruments Delete the entire tree!
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\PCI\ , \ISA, or \PCMCIA and delete registry entries containing any keys with 1093 in them.
Do not worry if any of these trees are not listed.

ORACLE 11G "real time apply" not work?????

we have a database original on ORACLE 10.2.0.4 and we upgrade it to 11.1.0.7.
after that we create standby database and tried to use "real time apply" feature.
Primary database can transfer log files to standby database and standby database also can apply logs. The problem is it can NOT work on "real time apply".
Ant ideal what wrong?

There are a couple of things to look at.
1. Real time apply requires standby redo logs on the standby database. On the standby database run this query:
SELECT * FROM v$logfile where type = 'STANDBY';
if you get 0 rows back you'll need to create standby logfiles
The general guideline is to size them exactly like your redo logs but add one additional standby log to ensure it doesn't cause a bottleneck.
2. Get the size of your logfiles:
SELECT GROUP#, BYTES FROM V$LOG;
3. For example if you have 3 redo logs that are 50 MB in size, create 4 standby redo logs 50 MB each and don't multiplex them.
ALTER DATABASE ADD STANDBY LOGFILE ('/Archive/DBSBY/onlinelog/slog1.rdo') SIZE 50M;
ALTER DATABASE ADD STANDBY LOGFILE ('/Archive/DBSBY/onlinelog/slog2.rdo') SIZE 50M;
ALTER DATABASE ADD STANDBY LOGFILE ('/Archive/DBSBY/onlinelog/slog3.rdo') SIZE 50M;
ALTER DATABASE ADD STANDBY LOGFILE ('/Archive/DBSBY/onlinelog/slog4.rdo') SIZE 50M;
4. Cancel recovery on standby
recover managed standby database cancel;
5. Restart recovery using real time apply
recover managed standby database using current logfile disconnect;
6. To validate that real time is working you can check a few places.
-It will say in the database alert log on standby that it's using real time apply
OR
-Check primary
SELECT status, recovery_mode FROM v$archive_dest_status where dest_name = 'LOG_ARCHIVE_DEST_2';
If the recovery_mode is "MANAGED REAL TIME APPLY" then real time apply is working, if it's anything else then we'll need to check more things.
NOTE that if you are going to allow your current primary to switch roles and become a standby then you'll want to create standby redo logs on primary as well
Sometimes recovery gets "stuck" and simply resetting the destination parameters can resolve it:
alter system set log_archive_dest_2='service=DBSBY valid_for=(online_logfiles,primary_role) db_unique_name=DBSBY LGWR ASYNC=20480 OPTIONAL REOPEN=15 NET_TIMEOUT=30';
There are some other things we can check next but let's start with the easiest fixes first.

Agent real time display not ready time is inaccurate

Agent Not Ready Detail in Webview-Agent Realtime Reports in CAD.
I am looking at the agent: Agent Not Ready Detail Report in Webview and comparing this to the Agent Real Rime Display in CAD. If I manually add the Not Ready times (state durations) from the agent ACD state log, they equate to the Cisco Web View agent report. However, the Total Not Ready column from the Agent Detail Display report in CAD does not sync up with either Webview or CAD. Its more than an hour off.
The Eastern managers are looking closely at these numbers now and one of the agents questioned the report in CAD today and brought this to a manager's attention. It is more than an hour off which is a big difference.
It was comparing the state duration for not ready from the ACD State Log Display (for example the 5 seconds at 10:15:04 in screen shot 1) to the total not ready time from the Agent Real Time Display Displays report (3:48:59 in screen shot 2). The total individual state durations of unavailable time from report #1 does not equal report #2 and I would think it should. If not explain why?
From CAD client > Real Time Displays > Agent ACD State Log Display. If you add up all the Not Ready times and compare with webview, it matches. No problem here.
From CAD client > Real Time Displays > Agent Detail Display (this doesnt match up with webview report or the total Not Ready times in Agent ACD State Log Display).
We're looking to know either
1. How exactly the not ready state time is calculated
OR
2. Where to find the information on how this is deteremined.
I appreaciate any response. Thank you.

Is it all agents or only one/some?

Exec.State and Start Asynchronous Call

In my application I like to start a VI asynchronously by pressing a button control. I just want to have one instance of the VI running so I let the caller test if the VI is already running. Unfortunately there seems to be a bug in the Exec.State property if you use it with a VI reference that has been built with a type specifier. It returns always "Running" as state.
I found a workaround by first openening a "normal" reference to the VI, questioning the Exec.State property, closing the reference and opening the "typed" reference. That works like I think it should.
My question: Is this difference in behaviour of the "VI" property node and the "VI Interface Type 1" property node by design or is this a bug in LV 2012 (I have not tested it with another version) ?
Matthias

I just wanted to point out about the very reason of the situation:
These are the options you can read by the Execution State property. As already marked, "Running" indicates that the VI is (at least) reserved for execcution. It does not necessarily mean that the VI is actually executing!
That being said, opening a typified reference to the VI already reserves the VI for running, hence your property node returns this value.
Your workaround seems to be well-thought out and should work in any case. Y already gave another option of handling this situation.
I doubt that there is another, better solution other to these two.

Mac Pro v's G5 Quad (Not again? But a real time battle not benchmarks)

I have an 8GB G5 Quad with the 7800GT graphics card. I have recently bought a stock Mac Pro and added 1 GB Crucial RAM giving it 2GB RAM in total, with the stock 7300GT card.
Having installed PhaseOne's CaptureOne Pro (universal) on both machines, I set about Batch Processing 204 Canon 1Ds MKII RAW files into 16 bit TIFFS. No corrections were made, it was just a straight forward batch.
Results: 2GB Mac Pro: 204 RAW - 16 Bit TIFFS (@ 96MB each) total time: 35 mins 14 seconds.
8GB Powermac G5 Quad: 204 RAW - 16 Bit TIFFS (@96MB each) total time: 58 minutes 22 seconds.
Never thought I'd hear myself (well read myself saying/typing this) but that's over 23 minutes slower for the Quad G5 with 4 times as much memory as the Mac Pro! Mac Pro 1.7 times faster. When time is money. . .need I say more?
Both machines were started up, nothing running other than whatever runs after start up in the background, nothing launched other than Capture One Pro. The files used were located in folders on the internal HD supplied with the machines (both have 250GB's: MP: Seagate, Quad G5: WD)
The Mac Pro toasted the G5 Quad - I'm gutted. Anyone want to buy a G5 Quad? lol
What's your experience with the Mac Pro?

As it is, most apps don't use 4 cores, never mind 8.
I'm lucky to see most apps use TWO cores effectively,
never mind 4 now. I see a precious few apps
benefiting from 8-core until developers start
thinking in a more multithreaded multicore way.
This problem is much much worse in the Windows world,
where aside from server apps multi cpu/core was very
uncommon in the consumer market.
Well said. Software engineers can do SO much with Multcore/cpu configs, but it's time and resources, and LOTS of code optimizing.
On the x86, at least it's now got everyone's full (well almost full) attention.
Pro app side will keep getting better. Cross platform software companies (adobe,etc) can focus more on x86 optimization without the worry about time/resources for optimizing on a powerpc as well. Can't wait for 10.5!

My iphone 3 is mainly showing "searching" then flicks up 5 bars but is still not able to make or recieve calls most of the time. Not sure why, wasnt an issue the day before!

I've done a complete reboot, software is all up to date, the sim works fine in another phone, so has to be something mechanical I think. Is it fixable?

[Solved] QJackCtl won't start in with real time.

Hey all,
I'm having a problem with QJackCtl, I got my version from Extra. The problem is that for some reason Jack won't start in real time mode using QJackCtl. Real Time is checked and marked under the set-up tab, but that little piece of info doesn't seem to make it to jackd. If I start Jack through CLI it works with real time, but not from the GUI.
I figured this out by starting JACK from the command line and then starting QJack. When I would do that it would be running in real time just without the rest of my settings (buffer,periods,sampling rate, etc). So in my head there's an issue with QJackCtl. I've tried to find a solution, but I can't seem to find one. This isn't the first time I've set JACK up on a system, but this is the first time I've had this problem.
The rest of the system is set up and ready to go. Rt Kernel, limits.conf and all other tuning is done.
Is there something I missed when setting this piece of software up? Any ideas?
Solved Edit:
Okay, so right after I posted this I got a crazy idea. When you enter setup in qjackctl on the first page there's a box for server path. The path defaults to "jackd". On that line I added "--realtime", so it looked like a basic CLI start-up of JACK and now it works!
So, if anyone else has this problem go to the Setup tab, in the setup window on the line that says Server Path it should look like this:
jackd --realtime
It worked for me and I hope it helps somebody else out.

Which volume? Assuming you're on the most common usecase (single hw audio device) then whatever command line you use (amixer for example) it'll work fine, it'll control the volume of the device rather than the pulseaudio plugin (so other playing apps get affected as well, which is probably what you want). The 'global' volume so to speak.
For multiple hw audio devices it gets tricky though.

Error in Real Time Collaboration

Hi
We got an issue in our project.
When ever any user log's into Portal it is giving a message called
With title Real-Time Collaboration(You are logged to the same portal already. Real-time collaboration capabilities will not be available in the current portal session until you terminate the other session and then restart this one by refreshing the browser or logging on again.)
We are using EP6 SP13
And we are having 2000 Portal users every one is getting this error in portal.
And After restarting the Server we are not getting that error. And again after a month it again starts.
Thanking you in advance for help
From
Srikanth

Hi Srikanth,
We also faced the same error and it was because the same users have already logged into the portal once or more than once.
The capabilities of real time collaboration feature might not work if an user has made multiple login to the portal using same id.
Hope the issue should be same with you.
With regards

About DTP with real-time access.

Hello Gurus,
       setting for error handling only has an impact while repairing a DTP request (repair) and during the conversion of the DTP to standard DTP (for example, to correct an error during extraction).
      will you please give a simpel scenario to explain above words?
thank you very much.

Hi,
Use :
With SAP NetWeaver 7.0, SPS 14, the following changes and enhancements are available for real-time data acquisition:
●      Changes to the menu and the context menu of the monitor for real-time data acquisition
The menu and the context menus for the individual objects in the monitor for real-time data acquisition have been standardized and enhanced. In particular, it is now possible to assign daemons and data transfer processes on various levels using context menu entries. For a complete overview of the functions in the menu and in the context menus, see Monitor for Real-Time Data Acquisition.
●      Assignment of daemons for InfoPackages and data transfer processes (DTP)
To assign InfoPackages and data transfer processes to a daemon, you can call the monitor for real-time data acquisition in the following ways:
○       In the Data Warehousing Workbench using the respective context menu entry Assign RDA Daemon.
○       In InfoPackage maintenance using the Schedule tab page, and in data transfer process maintenance using the Execute tab page.
The button names for jumping to the monitor for real-time data acquisition have changed here. To jump to the monitor, choose Assign Daemon.
●      Repair process chains for repairing a broken data transfer or a missing delta in the DataStore object
In certain situations, a gap in the delta of the DataStore object can occur if there is a closed request in the PSA but there is no corresponding request in the DataStore object. For example, this is the case if a DTP request has terminated due to an error in the transformation. Here, you can create a repair process chain to repair a missing or broken update from the PSA. The repair process chain contains a standard DTP as well as any further processes required for subsequent processing (such as activating the data in the DataStore object or subsequent process chains). When the repair process chain is executed, the complete delta is loaded from the source into the DataStore object and processes for activation and further processing are executed if required.
●      Process types for starting and stopping real-time data acquisition
You can use process chains to control real-time data acquisition using process types Start Real-Time Data Acquisition (RDA) Load Process and Stop Real-Time Data Acquisition (RDA) Load Process.

How to save data in a 4D array and make partial plots in real time?

Hi, this is a little complex, so bear with me...
I have a test system that tests a number of parts at the same time. The
experiment I do consists of measuring a number of properties of the
parts at various temperatures and voltages. I want to save all the
measured data in a 4-dimensional array. The indices represent,
respectively, temperature, voltage, part, property.
The way the experiment is done, I first do a loop in temperature, then
in voltage, then switch the part. At this point, I measure all the
properties for that condition and part and want to add them as a 1D
array to the 4D array.
At the same time, I want to make a multiple plot (on an XY graph) of
one selected property and part (using two pull-down selectors near the
XY graph) vs. voltage. (The reason I need to use an XY graph and not a
waveform graph, which would be easier, is that I do not have
equidistant steps in voltage, although all the voltage values I step
through are the same for all cases). The multiple plots are the data
sets at different temperatures. I would like to draw connection lines
between the points as a guide to the eye.
I also want the plot to be updated in the innermost for loop in real
time as the data are measured. I have a VI working using nested loops
as described above and passing the 4D array through shift registers,
starting with an array of the right dimensions initialized by zeroes. I
know in advance how many times all the loops have to be executed, and I
use the ReplaceArraySubset function to add the measured properties each
time. I then use IndexArray with the part and property index terminals
wired to extract the 2D array containing the data I want to plot. After
some transformation to combine these data with an array of the voltage
values in the form required to pass to the XYGraph control, I get my
plot.
The problem is: During program execution, when only partial data is
available, all the zero elements in the array do not allow the graph to
autoscale properly, and the lines between the points make little sense
when they jump to zero.
Here is how I think the problem could be solved:
1. Start with an empty array and have the array grow gradually as the
elements are measured. I tried to implement this using Insert Into
Array. Unfortunately, this VI is not as flexible as the Replace Array
Subset, and does not allow me to add a 1D array to a 4D array. One
other option would be to use the Build Array, but I could not figure
out if this is usable in this case.
2. The second option would be to extract only the already measured data
points from the 4D array and pass them to the graph
3. Keep track of the min. and max. values (only when they are different
from zero) and manually reset the graph Y axis scale each time.
Option 3 is doable, but more work for me.....
Option 2: I first tried to use Array Subset, but this always returns an
array of the same dimensionality of the input array. It seems to be
very difficult, but maybe not impossible, to make this work by using
Index Array first followed by Array Subset. Option 3 seems easier.
Ideally, I would like option 1, but I cannot figure out how to achieve
this.
Your help is appreciated, thanks in advance!

Oracle JRockit Real Time 3.1.2 and weblogic?

http://www.oracle.com/technology/software/products/jrockit/index.html". I go to the website, and find a software called: Oracle JRockit Real Time 3.1.2 for windows 64 bit. My question is: In order to let weblogic 9.2 works in windows 2003 R2 64 bit machine, SHOULD I MUST DOWNLOAD "Oracle JRockit Real Time 3.1.2 for windows 64 bit"? Or I don't need to download anything? Actually, I just download a file called jdk-6u18-windows-x64.exe. Please clear my question, thanks! One more thing, what is the functionality for Oracle JRockit Real Time 3.1.2? Is it a kind of JRE ?

Hi,
For more information on JRocket Real Time have a read of :- http://www.oracle.com/technology/products/jrockit/jrrt/index.html
As far as I am aware you don't have to install the real time product you can installl the JRockit JVM and use that with Weblogic, I think newer version of JRocket come bundled with Real Time which is the JVM and monitoring and analysis tools. There are still standalone JRocket JVM installs available, you can get them from oracle edelivery.
JRocket is a JVM but optimized for use with Weblogic, so you should get better overall performance.
Cheers

Embedding a countdown timer, that is linked to real time, into a video

Hey,
I'm trying to figure out how to do something I have never done and got no clue where to start.
What I am trying to accomplish is to make a 10-sec video that has a real time countdown clock to a certain part of the day (Ie: 5 hours and 10 secs left till 8 pm). Designing the clock is simple, what I cannot figure out is what program i should use and how to make it link to real time. Is this possible in after efects or do i need to use flash proffessional or something else. To give you a little bit more information, typicly I design ads that just run on a loop, this ad has to be different because it needs to run in a loop and somehow go and get the countdown according to real time and not just the videos length. (I've heard of somehow making a flash SWF file that either links to computer or RSS file, but I have no idea how to do that in aftereffects.) This is what i can find, but NOT what i want: https://www.youtube.com/watch?v=K-ilCXXAQGA&app=desktop I want it to use real time for countdown.
The media player running this 10-sec video ad is apparently compatible with Flash SWF.
Any help is good and if anyone can point me in the right direction that would be great.
Thanks in advance .

Video is video. You have to use another app to overlay something else. HTML 5, javascript, Flash. Can't be done in AE.
