LabVIEW executable not feasible using the asynchronous call

• Start the asynchronous call brutal Typedef Bug

  There is a nasty bug which I think is the cause of many anomalies weird I see with the events of the user, like where some get fired and if I probe the refnum of the event on a VI that was launched using the asynchronous call node start I get some weird value for reference as 8450 or 5500 instead of some great typical integer. It is not also match the value that I get when I initialize the reference. This happens only intermittently, but I can reproduce the bug that I see on a smaller scale to a certain extent. This is not exactly the same as what I see in my current project, but I guarantee you both are related. Also, I'm pretty confident that this has to do with the help of LVlibs as well.

  So... to reproduce some questions:

  Unzip the attached code and open the project

  Open Main.vi. It is hard to see because it's pink, but notice the point of constraint on the node to call asynchronous start. This is provided at this point because I have a cluster of non-typedef in the connector pane, but a TD cluster plugged into it.

  Now open AsyncCall.vi

  Drag the eventcluster.ctl of the project on the façade of the asynccall.vi

  CTRL + x on the typedef cluster that has placed you on the front panel

  Select the non-typedef cluster by clicking it

  CTRL + v to replace the TD not cluster with the cluster of TD and save

  Return to main.vi, you will notice that the point of constraint does not go far.

  Open context-sensitive help and notice that the ctrl types match, but it's as if LV does not recognize it on the beginning of the node of the asynchronous call.

  Remove the node from asynchronous start call, then replace it. The cluster to the top wire. Voila, no point of constraint.

  Second question - same result but different method to get there.

  Now that you have components of connector typedef stress points and no more because you've taken the first steps of this 'exercise', remove the EventCluster.ctl from the library and record.

  WOAH, look the points of back strain, because node call asynchronous start still referencing the typedef cluster that he thinks that should be in the library. This can be seen by removing the cluster on main.vi and then right-click on the node to call asynchronous start on the side of the connector and creating a new constant of cluster

  It is creates a greyed out of control! Why? Well, we will reopen the context-sensitive help. Whadda you know, it's always looking for the control in Bug.lvlib that no longer exists.

  Now, the question that I'll have in my complete project that I can't post and can not reproduce on a smaller scale updates the typedef causes the dot of coercion. Otherwise I can't update my typedef cluster that contains all my events without going and replacing EVERY SINGLE launch async call node EVERY time I have add a new event.

  Major problem.

  Please let me know if these steps to reproduce were not clear or you have difficulties to reproduce the problem. I use LV2013 SP1. I opened the project in 2014 to see if it has been fixed in a later version, but I saw the same thing.

  I can repro with measurements of @GregFreeman and also confirm that I saw this same issue at least since the LV2012, but they have not reported it having not been able to provide a minimum test (thanks, @GregFreeman!) scenario

  For the record, it seems that the bug here, it is the spread of type sometimes makes an incorrect assumption / optimization as to if the conpane of the start the asynchronous call node must be updated when the source changes.

  A more obvious change - say, add/remove an entry, reverse order, or change data types altogether - always seems to spread properly.

  Incorrect optimization seems to be a terminal retains the same type of database, but transforms the type definitions - or, if the type definition is re-related or related outside a library owner.

  @GregFreeman watch the bug goes from non-typedef typedef, but it's actually worse in the other direction - when a link to a missing file is maintained.

  Call the asynchronous starting node seems to maintain a list of links that is distinct from that of the VI, and this list of links separated, this is what seems to not be properly invalidated. For example, in the screenshot, I illustrated example of Greg that the node generates no error in the compiler even after parenthood and rename the Typedef...

  

  ... even when we "Create Constant" on this terminal incriminated with list obsolete links, we get a compilation error. Since then, the grayed out type highlighted in the contextual help cannot be found, because 'Bug.lvlib:EventCluster.ctl' no longer exists, but the list of links separated from this node was not notified:

  

  It is worth noting that "Bug.lvlib:EventCluster.ctl" does not appear in the list of links of the VI at this stage.

  Often, no compiler error is generated after this failure occurs and as Greg reports, you could end up with undefined behavior (e.g. suspicious Refnums and events that seem to not fire not) (and I'll add it to this list a hearty portion of DAborts with diversion total number of messages).

  In addition, you * could * receive errors of cryptic linker for generations, but maybe not (the above screenshot, you'll notice I added two builds, neither of which seems to have a problem of building). (It seems that the broken link is travel with the distribution of the source, even if 'Disconnect the definitions of Type' is selected during the build process. That is why I believe anecdotally that node maintains a list of link separately the list of VI, and it's maybe part of the problem).

  It is noted that during this refactor (de-parent and rename) all screws and control remained open and in memory and all files have been saved. No funny business where LabVIEW would be unable to update links in a file that was not in memory.

  Another note - in the original example, all source files have been unifiles, and I can add anecdotal report this bug is much more insidious when separate compiled Code is active on the source files. In this case, the source may appear to be perfect - no point of constraint, no link expired - but the code that is currently running can be broken. In other words, what you see is not what you get, which makes debugging impossible. (This bug in particular is one of the few who makes "Cache of compiled clear objects" become a normal procedure controlled throughout the application development)

  Anyway, I wanted to draw attention to this issue, given that this thread is not yet associated with a CAR and it's a serious bug that generates a behavior undefined performance caused by a fairly normal refactor now has a well-characterized small repro case.

• deployment of the asynchronous call

  I need deploy an executable on a computer of the client and for the first time, I need to use an asynchronous call in my program I don't know how I'm going to keep the path to the 'reference of VI Open' valid after I build and deploy the application.  The obvious way would be to use a configuration file to allow me to set the path independently of the LabVIEW Application.  However, when you include A VI in the always 'include' is not an EXE so not include a file in the folder of generation, which in fact had reference on the host computer.

  Teaching tips on how to proceed would be to very help full to learn to deploy this application

  Attached is a code snippet of how I am currently using an asynchronous call

  Thank you

  Mark R.

  That's how I always call a VI by reference.  Saw the ref static VI causes LabVIEW load this VI in memory and be able to find it by name when opened.

• Ideas re: ' Connect-VIServer: could not connect using the requested protocol "failure

  I know, it's a matter of weakness, but I hit the wall on this one. I've even got desperate enough that bouncing private LuD, and I tried everything we discussed, but I'm still @ deadlocked.

  I developed and tested several scripts that I am finally ready to go with Prod.

  I get this error when I am trying to connect to Vcenter server or host of the cmndline of vitoolkit (and obviously in scripts).

  «Connect-VIServer: could not connect using the requested protocol.»

  I'm runing the vitoolkit FROM the server VCenter, so I wouldn't exepct the local to be a problem connection. I expect calls the ESX servers as questions) (we have several firewalls in the game). But even once, on-site I would not expect a problem.

  I checked my ports of VC and even more precisely called listener in the connect command, but it does not help.

  I tried to watch the ports through various lines of command, but I don't see anything.

  Any suggestions?

  Add - confirm: $false and it won't be quick.

They had followed my computer (Windows 7) and noticed problems with it because it was very slow at startup (TRUE). He said that my computer has been hacked. He gave me my product windows (OK) key and me had discovered my event log that have trouble with my printer. Then he asked permission to take over my computer and fix the problem. At this point, I hesitated.

  The question is done Microsoft outsource monitoring Windows 7 computer in trouble. It seems very likely.

• The listener is down: even if a listener with the name "AUDITOR", is running on this host at the port: "1521", it has not started using "the target LISTENER. ORA file.

  
  I moved a listener on a host in a House different oracle. The headset works fine, but EM 12 c shows that the listener is down with the following summary:

  The listener is down: even if a listener with the name "AUDITOR", is running on this host at the port: "1521", it has not started using "the target LISTENER. ORA file. CORRECTIVE ACTION: To monitor this "EM listener target" with its current configuration, you must stop the process of listening running and start it using the Listener parameter file: opt/oracle/product/12.1.0.2/network/admin/listener.ora. Alternatively, you can update "this target LISTENER. Location ORA setting"with the location of the listener running, which started using the: opt/oracle/product/11.2.0.3/network/admin/listener.ora.

  EM 11 g, I simply changed the configuration of the listener for the different oracle home, argued the change and in a few minutes the listener would show that 'UP' with the oracle of new home. I upgraded to MS 12 c (12.1.0.4) and can't find how to do this. Can someone give me the procedure.

  Thank you

  Ron

  Hi Ron,

  Can you please do the following?

  -Create a for the listener listener.ora file, stop and start the receiver using the listener.ora file. If the file is located in a default location, set the TNS_ADMIN environment variable to that location before you start the listener.

  -Log on to the EM console, go to the homepage of the listener.

  -In the Oracle Listener menu, select target Configuration > Configuration of the analysis.

  -Ensure that the parameters, including the Listener.ora directory, are properly.

  Kind regards

• Get - VM: with "xyz" name VM is not found using the specified filters.

  Hello everyone!
  
  I have a script that reads a CSV with multiple host names, to connect to vCenter and should get the name of host, ip and PortGroup information to generate an external file of CSV.
  It happens that several cases vm does not exist in vCenter and returns me the below error:

  Get - vm: 04/07/2016-14:41:58

  Get - VM

  VM with the name "pxl1sso00008" was not found using the specified filters.

  How would I do to get the information from an input file, see the vCenter and if this positive results write the file, ignoring errors. Ideally, if not to find the machine, simply create a line in the output file with only the hostname with the rest in white.

• path to vi the asynchronous call

  I'm trying to implement a splash screen that calls my main VI of asynchronously and displays messages during the charge of the VI.  Everything works fine in the development system, but it is not the case in EXE.  This is my first attempt to call a VI like that so I don't know that I'm missing something simple.

  See the image as an attachment.  The static reference points to a location on my server but I want to run the VI which is "Still included" in my EXE build, not the VI of the server.  The path of the VI comes back here is a combination of the path of the server and the location of generation, which is obviously not correct.

  What is really strange for me, it's that the main.vi is in fact running even if the path is incorrect.  The splash screen displays messages received from the hand, but when it is charged to the configuration settings, it fails because the vi path is c:\program files\tester\main.exe\z\labview\tester and it does not find my INI file.  How can I dynamically load this VI and even power give him my refnum of notification for my splash screen and return to the correct path of VI?  I tried to remove the path below property node and just add a constant path with main.vi as the value.  But it seems to get the path of the strict type reference (I understand is type only).

  

  I'd be willing to bet that your complete and complex application calls some VI who lives on the C drive, so to avoid any potential ambiguity, it uses the full path in the compiled (by chance) application, but on different drives. Your simple application probably calls subVIs that are only on the Z drive, so there is no possibility of confusion and it uses a shorter common path as a starting point.

• labVIEW does not correctly read the data

  I'm new to LabVIEW (use it for a subject in College), but I coded a short program which counts the fronts and edges of a signal (to be used with the addition of a quadrature encoder).

  I tested it at low frequency using the block to simulate Signal and it works fine, but as soon as I have the pump up to anything above 4 Hz, it starts to play up (including a positive benefit as a negative benefit). 10 Hz, it is not the edges at all. Same thing with the encoder - when turning very slowly the counties to register very well, but even a moderate speed and it will start missing.

  Don't know what the issue is. The code is pretty simple, so I don't know how this would have caused the problem. Here's a copy of my counter block (the entrance of true/false indicates whether to count the upwards or downwards).

  Are adjust you the length of your signals simulated when you vary the frequency?

  Your Subvi seems to be just looking for a transition in a waveform.

  Your simulated signal Express VI is set up for the sampling frequency of 1000 Hz and 100 samples.  If the outer loop iterates at 10 Hz.  If your frequency of 5 Hz, then you will have 1 transition in the waveform section and you will be able to detect it.  You go higher in frequency, then you could have multiple transitions in your waveform, but the Subvi seeks only to the first, and he might not even have this one.  Remember when I said that you need to run your loop two times faster than the incoming wave?  Well now you see that the ratio of 2:1.

  Adjust you the length of your simulated signals that you set the frequency so that you don't get multiple transitions on the waveform that you generate each iteration of the loop.

• How to get sqlplus not to use the output of size documents fixed?

  I want to generate the sql code to clear all data in tables in the database of flat files, one file per table, one row per record.  I thought I'd try to use the ascii code for characters inherited 31 as a delimiter to separate the fields and start sqlplus. But a problem is how do you get to specify linesize? Are there not a way to get out of creating fixed size records in sqlplus? I would prefer each line to just be so great that it must be rather than set the linesize being the absolute maximum. (32767) or understand what the maximum size is on a per-table basis.

  Is it possible to do?

  tell him to get rid of these spaces.

  OOPS I forgot something. A problem with this is that if there are embedded newlines \r \n one of those or both in a field, then this format that uses the newline to indicate the end of the recording is toast. And I know that they are inclined to do this. (Users can not live with them, can't live without 'em). More on that later.

• Try not to use the DBA role

  Hello all,.
  
  I'm now working with a database 11g on windows platform that has many schemas (200 +). Each schema got DBA, CONNECT and RESOURCE roles. I am trying to determine the minimum privileges is required for each schema.
  
  I started by revoking the DBA role, then grant the role of RESOURCE for certain privileges in the role of RESOURCE are also in the DBA role and are lost when the DBA role is revoked.
  
  I then use the front-end application to see what broke. The front-end server's Active Server Pages (.asp), I know null on .asp.
  
  I'm getting an ORA-06508: PL/SQL: called program unit could not be found.
  
  The "unit of program being called" is a call to a package.procedure with parameters. The package and procedure exist and are valid within the scheme used.
  
  Any ideas about which 202 in the DBA role privileges are required?
  
  Thanks for your help,
  
  Bob

  Bob,
  Nice detective work!

  Many details on the privileges based on roles is here:
  http://docs.Oracle.com/CD/E11882_01/network.112/e16543/authorization.htm

  The section "how roles work in PL/SQL blocks" explains when using PL/SQL roles. (Procedures 'DEFINER rights', the value by default, use no roles - "The rights of the applicant" procedures and anonymous blocks are.) Most of the time you don't have to grant privileges to table directly to other patterns that reference them in PL/SQL.
