SQL Toolkit crashing with multiple threads

• Problem with multiple threads

  I have a program that interacts with an ESX 3.5 server using the VIX API, written in c#. I'm from multiple threads in c# program with each thread running an automation process which creates a connection to a virtual machine on the ESX Server, some automated process, and then disconnects. I'm having problems with this. When I call Disconnect() from one of the threads, it seems to cause problems with my other son if they have not yet disconnected. I connect to an another VM on the server in each thread. The problem is if I don't call disconnect, I get errors, but if I call disconnect in a thread it causes errors. Y at - it something similar? Any suggestions on how to make this run smoothly? Thank you!

  This sounds a lot like you are getting hurt by the host sharing of handle.  If HostConnect() is called with the same parameters, the handle of the host gets reused.  HostDisconnect() will clean this handle, even if his commune.  It's actually documented behaivior.  We have also decided that there may problems like the one you have reached, so it will be removed in a future release.

  So your application will share the handful of host among all discussions, and as soon as we call disconnection, the host handles in other countries also becomes invalid.

  Make a unique HostConnect() and share this handle inside threads is a way to avoid this.  HostConnect() is generally quite expensive, so we recommend in all cases.

• Create a procedure SQL with SQL toolkit

  Hello

  I use the SQL Toolbox to get data from a MySQL database (using ODBC connectors).

• Database MySQL with SQL Toolkit

  Hello

  We use CVI 2012 and the SQL Toolkit 2.2 and we want to connect to a MySQL database.

  The MySQL database has been created with MySQLServer. When we try to connect with the BD connection, we get an error.

  How can connect us to the MySQL database?

  What do we have to type in the connection string to the DB? What is the name of the database, the path to the database or anything else?

  Have experience with the SQL toolkit?

• Svchost.exe is free running and leaves multiple windows open all gel. Re-loaded windows XP after a crash with original rescue records.

  Original title: Windows XP - free race - is lost.

  Just re - load windows XP after a crash with original rescue discs, svchost.exe is free running and leaves several Windows Open gel, all on and offline. Any ideas? I ran ms-fixit beta for all listed. I also disabled Norton and now use Windows Defender, still no luck.

  Hi MarkBerri,

  ·         How long have you been faced with this problem?

  ·         Did you do changes on the computer before the show?

  Svchost.exe is a process name generic host for services that run from dynamic link (dll) libraries. The Svchost.exe file is located in the folder C:\Windows\System32. At startup, Svchost.exe checks the registry services part in order to build a list of services that it needs to load. Multiple instances of Svchost.exe can run at the same time. Each Svchost.exe session can contain a grouping of services. Therefore, separate services can run, depending on how and where Svchost.exe is started. This grouping of services enabling better control and easier debugging.

  Svchost.exe groups are identified in the following registry key:

  HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Svchost

  You can run the auditor of system files on the computer.

• With CVI SQL Toolkit, how to add the new variable param column in a table.

  Dear all:

  I used the CVI Sql toolkit to create a database, but now I don't know how to add a new column to a table in variable param.

  I know, to add a column with the name of constant column could be down by below:

  DBImmediateSQL ((hdbc, "alter table table1 add column1 char [100]");

  But if Column1 is a param variablae how can I write the code? Please advise?  It will be appreciated if you could give me an example.

  Best regards!

  HI -.

  If you look at the parameters that you pass to the SQL function, you can see that the second parameter is a string constant. In your code, you can create an array of characters (string). You can then use sprintf to programmatically determine what will be the contents of this variable. In the function call, you can put the variable instead of the literal string, and you will have a customizable SQL statement.

  Hope this helps-

• Audition with multiple monitors and nVidia - crashing / flicker

  When using mulitple monitors hearing signal several times at the start, take longer to start and often crashes.  When you use a single monitor, hearing throw very well.  We run Windows 7 Pro on to Lenovo T430 with nVidia NVS 5400 M card.  I have also some Lenovo x 230 who have Intel Graphics.  When you use multiple monitors with Intel graphics card, it works fine.

  E-mail log files (na not see an option on attach firmly to this topic).  It seems that the main difference is not only with multiple monitors, but rather with nVidia graphics.  Multiple monitors on a laptop computer Intel Graphics ONLY works great... no problems.  Multiple monitors on a computer of graphics from nVidia has problems.  However, when the didn't use a monitor on nVidia computer, it works fine.

  I do the work of an EJB on Weblogic Server and I used the JDev "Entities of Tables" Wizard to generate the code for each table.
  
  The code works fine most of the time. However when there are multiple threads using the EJB, I think that the allocation of the sequence becomes the same set IDS on different threads. The Session Cache for my persistence has the default "(soft low)".
  
  Everyone seems it before and you know a solution?
  
  The annotations that I use for the generation of PK for the ID column (where the unique constraint is violated) are:
  
  @Id
  @Column (nullable = false)
  @TableGenerator (name = "UserContextStatesSeq", table = "SÉQUENCE",
  scheme = "SDE", pkColumnName = "SEQ_NAME,"
  valueColumnName = "SEQ_COUNT"
  pkColumnValue = "BDSS. USER_CONTEXT_STATES «(, allocationSize = 50).
  @GeneratedValue (strategy = GenerationType.TABLE,
  generator = "UserContextStatesSeq")
  Private Long id;
  
  
  The code for the EJB is shown below (only the relevant parts):
  
  
  @Stateless (name = "RuntimeEJBBean")
  @Local
  public class RuntimeEJBBean
  implements RuntimeEJBLocal
  {
  @PersistenceContext (unitName = "persist")
  Private EntityManager em;
  
  public RuntimeEJBBean()
  {
  }
  
  Private Sub createNewContextState()
  throws the Exception
  {
  NewState UserContextStates = null;
  Try
  {
  newState = new UserContextStates();
  EM. Persist (newState);
  ...
  EM. Flush();
  catch (System.Exception e)
  {
  ...
  }
  }

  According to your annotation you use table named SEQUENCE to generate the id I suggest switching to sequence if you use Oracle.

  So instead of

  @TableGenerator (name = "UserContextStatesSeq", table = "SÉQUENCE",
  scheme = "SDE", pkColumnName = "SEQ_NAME,"
  valueColumnName = "SEQ_COUNT"
  pkColumnValue = "BDSS. USER_CONTEXT_STATES «(, allocationSize = 50).
  @GeneratedValue (strategy = GenerationType.TABLE,
  generator = "UserContextStatesSeq")

  use

  @SequenceGenerator (name = "UserContextStatesSeq", sequenceName = "USER_CONTEXT_STATES_ID", allocationSize = 1)
  @GeneratedValue (generator = "UserContextStatesSeq")

  and db to create sequences:

  CREATE THE SER_CONTEXT_STATES_ID MINVALUE SEQUENCE 1 WITH AN INCREMENT BY 1 1 COVER 50 ALL;

  allocationSize = 1 in @SequenceGenerator with CACHE 50 in phrase makes any id generation caching done at Oracle no ORM.

  If go to the sequence isn't an option, I would check if all error a bind ID with values such as XXXX01 or XXXX51. If Yes, then taking into account the fact that you have allocationSize = 50, it would mean that EclipseLink does not correctly synchronize award of the new id if that's the case then maybe change allocationSize 1 would help.

• Problem connecting SQL toolkit Win7

  I use CVI 2013 and tto toolkit (2.2) of SQL to connect to a mySQL database.  I can connect to properly using my development computer, but not with the target.  Both computers are running 64-bit Windows 7 Professional (SP1).  I used to start the 64-bit ODBC drivers (mysql-connector-odbc - 5.3.2 - win64.msi) on both machines.  After I got hurt, I found an article in the Knowledge Base which indicated that I should probably use the 32-bit instead.  So I deleted the drivers of the target and installed those 32-bit using odbcad32.exe found in Windows/SysWOW64.  No change.

  I use the sample browser2.prj project included with the SQL Toolkit (default: C:\Users\Public\Documents\National Instruments\CVI\samples\sql\apps) to test the functionality of the SQL tool.  I create a distribution kit, including the runtime shared on the development computer and install it on the target.  I traced the problem to the call of DBSources() - it returns a - 100 (who, the hand is not among the list of database error codes).

  On both machines the ODBC drivers seem to work.  I can get to the database using Panel-> administration-> Data Sources (ODBC) tools.  Select the user DSN or system DSN database, and then click Configure open the MySQL Connector/ODBC Data Source Connection window.  By clicking Test in this window will connect to the database.

  If the problem seems to lie in the way that ICB connects to the database.  I'm naïve now, any suggestions would be greatly appreciated.

  Sorry if this is a stupid question:

  Have you followed the instructions help-> Reference Library-> library Toolkit SQL-> SQL language reference-> distributing a SQL Toolkit executable or a DLL?

  Or is it a mistake you get despite following these instructions?

• Urgent: continous recorders of NIDAQmx and other instruments with multi-threaded vc ++

  I'm working on a software with vc ++ to control several instruments including a NO-DAQmx6289. For example, the features of the software.

  2. connect with function via port RS232 1 generator, sending triggered bursts to the real-time features generator change state Ultrasound (G_usstatus) variable.

  3. connect with optical switch via RS232 2 port, send signals to switch between the two input channels (0,1) and six output channels (2,3,4,5,6,7) to the specified user to sequence and time interval (default: 150 ms), real-time change the channel connection variable (G_optchannel).

  Now the problem is the data acquired with daq card does not match the corresponding registered swtich optical status (G_optchannel, which specifies the light connecting channels). High readings expected certain status really appeared in any other situation.  It seems that there is a misalignment of the multi-thread data. Because the optical switching State passes to 150ms, so I put DAQmxRegisterEveryNSamplesEvent to be trigued each 50samples, which means 50ms with 1 kHz sampling to avoid missing the changes. I also check if there is any change of status during the DAQmxReadAnalogF64, by registering l_optstatus_s and l_optstatus_e, which are actually the same. I wonder if this is because the data are first registered in the buffer. When the software starts reading, at that time, optical swtich status no longer reflects the State when the data was recorded first. Is it possible to fix this?  Thank you very much!

  kGy,

  I'm glad to hear that you are progressing with your project.  Timestamp data are always a bit tricky, because the process of querying a counter on the CPU is done asynchronously with the acquisition of your DAQ hardware.  However, your equipment will ensure that the relative chronology between samples is consistent (in your case, the data will be sampled every 1 ms).  And since you have changed your program as you are now all samples acquired reading, you know that each sample follows the previous 1ms.  So, if I were to implement this I think that I take an initial horodotage when I started the task and to calculate the timestamp for all samples following this timestamp (timestamp SampleN = (*.001s + horodotage initial N) or timestamp SampleN = timestamp SampleN 1 +. 001 s).

  I would go to do that, rather than the timestamp of the end of the reading for the following reason.  As I mentioned previously, the reminder of your reading will run when the OS is planning.  Therefore, it is possible that it gets delayed or does not exactly in phase with the acquisition of hardware, and make adjustments to your code to handle this problem.  However, when you're timestamping there is another thing to pay attention to.  It's the fact that your hardware has a FIFO where sampled data can accumulate before getting transferred to the memory buffer that reading from (for example if the bus PCI were busy when the sample was acquired).  Now assume that the stars aligned against us and get the following:

  (1) the operating system is busy with other things, and our reminder read gets delayed a few ms.

  (2) at the same time, another device connects the PCI bus (or part of the data path between your device and the memory used for the buffer).

  (3) one or more samples is momentarily blocked in FIFO of the device.

  If you were to read data timestamp at the moment, your timestamp would reflect the data in the buffer as well as data that was flying in the FIFO of your device.  However, you can only read data in the buffer.  Thus, time stamp applied to data that you just read would be a millisecond or two later they should be.  Suppose that on the next read reminder, this condition has cleared up itself.  This timestamp taken here would be accurate, however, you will need to return some additional samples (those who were stuck in the FIFO last time).  If you backcalculation your timestamp at this stage, I think that the timestamp calculated for these ecaple timestamps calculated on the previous reading.  It wouldn't be ideal, nor would it reflect when the data has been actually sampled.

  One of the remaining challenges is how exactly the start of time stamp feature.  To do this, I would like to add a call to DAQmxTaskControl (taskHandle, DAQmx_Val_Task_Commit) before calling DAQmxStartTask.  This step will advance the State template DAQmx as far as possible without actually starting the task.  This will help to DAQmxStartTask as soon as possible.  Now, before the appellant beginning or immediately after, I would take my initial horodotage (perhaps timestamp before and after and take the average).  Then I would use this original time stamp and my sampling rate known to calculate timestamps for all the rest of my samples.

  That got a bit long, but I hope it has been helpful.

• SQL toolkit connection problems on ICB

  Hi all.

  I wrote this post because I'm not able to find a solution for the problem of the Telegraph...

  I have developed a program that uses SQL Toolkit, the CVI 9. I have access to a MS Access 97 database, using an ODBC (DSN = MyProgram) connection.

  The program works well, on windows 7 and windows XP (windows xp is the operating system of the end user).

  However, when I install the program on the pc to the end user (windows xp) and then create the DSN user on ODBC connections, I got an error during execution of the program. We mean the error is not possible to connect to the database (its the ODBC connection).

  As I said, on the other machine, different, with windows xp, it works!

  I'm a little lost. Do I need a special component installed to SQL Toolkit fine work?

  The PC with XP where the application works, has the same applications installed as the end user's PC.

  I tried to install on the end user the LabWindows CVI SQL Toolkit with pc, and I checked that when connecting to the DSN will be tried, I get "unknown error."

  Help will be very appreciate!

  Run it on pc without Sql toolkit, you must copy the cvidb32.dll into your your windows system32 folder.
