• Cannot install the sample applications manually

  Hello

  I'm having a time difficult installation SDK push sample applications on a remote computer. I try a manual install of Tomcat. The machine runs on Linux Red Hat.

  The error I get is:

  [org.springframework.web.context.ContextLoader.initWebApplicationContext()] - Context initialization failed
  org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'registerListeners' defined in class path resource [sample-push-initiator-context.xml]: Invocation of init method failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Communications link failure
  
  The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.)
  

  It looks like a problem with the JDBC connector, but I do not know how to solve. Among the things that I've done are:

  • Generate the database manually.
  • Fill the PushSDK.properties with the database and JDBC information. Copy this file in each directory WEB-INF/classes of applications examples of
  • Copy the mysql connector jar file in the directory WEB-INF/lib of each application
  • Edit the file app.properties with the information from my BB (app id, base url PGG etc.). Copied in the directory WEB-INF/classes of applications. I did the same thing with suspension - context.xml and app - context.xml
  • Edit conf/server.xml of Tomcat to set the http and https ports and the UTF-8 encoding for the request URL query component. In fact, I have only port 8080 available in the machine and I have configured HTTPS to work.
  • A self-signed certificate and shows its location in the conf/server.xml file. Indicates its location in conf/server.xml
  • Edit bin/catalina.sh to set the JAVA_OPTS UTF-8 encoding

  The initial Tomcat page seem to be working in https://machine_ip:8080.

  But there are errors with the BB apps:

  • https://machine_ip:8080 / sample-push-initiator returns 404
  • https://machine_ip:8080 / pushsdk returns 404
  • https://machine_ip:8080 / debug-Portal opens the Debug Portal, but displays the following message:

  Internal Server Error: 
  
  Sorry, we are unable to properly process your request at this time. Please contact a system administrator to investigate the problem by examining the logs.
  

  Does anyone have an idea of what's going on? I would be very help appretiate

  Hi all!

  Finally, I could solve this problem. MySQL was not allowing the JDBC connection. I have

  delete the line:

  skip-networking
  

  in MySQL configuration file (/ etc/my.cnf) and now the sample applications seem to work ok.

  I still cannot subscribe to the good customer, but that's another story...

  The problem here is that the query is not designed to handle the case where more than one employee sharing the same value of ENAME. In the sample data that comes with the Application Express, there is no name used twice, so the problem does not occur, but it's easy when playing with the data to add a duplicate and then name that breaks queries in the service who assume a single result is possible and that's why the error message. This was the case in my own work space.

  I had to delete the EMP and DEPT tables and then perform the SQL workshop | RESTful services | Reset the sample data to restore the original data set, and then the service works as expected:

• "Cannot complete order because the extension could not be loaded." with the sample CEP5

  Hello

  I have trouble with my extension porting to CEP5. I get the error message "Cannot finish order because the extension could not be loaded." when I open the Panel.

  Is it possible to get more information about what happened and why? My post was properly signed zxp and managed Extension installed without problem.

  Also, to debug the problem, I tried to open the Test HTML CEP Extension - https://github.com/Adobe-CEP/Samples/tree/master/CEP_HTML_Test_Extension_5.0

  I copied on '~/Library/Application Support/Adobe/CEP/extensions/com.adobe.CEPHTMLTEST ", created .debug inside (https://gist.github.com/m6k/39a49786b7a85a9e312b), empty the file inside Photoshop CC 2014.app .debug (to remove the verification of the signature). When I open Photoshop CC 2014, I see test listed in menu extension panels, but when I try to open them, I also get the error "cannot complete order because the extension could not be loaded.".

  
  

  No reference to what I'm doing wrong and what I can do to debug this problem?

• Instruments of the sample of user-specific does not see EXS24

  Logic Pro X 10.2.0 EXS24 sees the Instruments of the sample in my folder/library specific to the user, but only those in the global folder/library.

  But Logic Pro 9.1.8 EXS24 can see both.

  Background:

  I had my mid-2010 27 "iMac running OS X 10.8.5 and Logic Pro 9.1.8 (as well as Logic Studio 7) I upgraded to El Capitan without incident. I bought and installed Logic Pro X on the App Store without incident.

  The menu of Logic Pro X EXS24 instruments shows that the Instruments that are in the global folder:

  Instruments of Macintosh/Library/Application Support/logic/Sampler

  The menu Logic Pro 9 EXS24 instrument shows the Instruments that are in both aggregate AND user-specific folders.

  The menu instrument show the structure of:

  Instruments of Macintosh/Users/me/Library/Application Support/logic/Sampler

  It adds an entry listed as 'Factory' under which it places the Instruments found in:

  Macintosh/Library/Application Support/logic/Sampler instruments.

  If I load a project in Logic Pro 9 that uses some of the Instruments found in the user-specific directory in Logic Pro X, Logic Pro X reports errors that he cannot find the instruments and gives no possibility to 'find' and opens the project with a bunch of sounds of the sinusoid default loaded instead of the missing instruments.

  You can see two directories with the Global Directory on the specific to the user on the right and the left in my attachments.

  I have also attached a picture of the EXS24 Instrument Menu in Logic Pro 9 and Logic Pro X.

  Any guidance would be greatly appreciated.

  Thanks in advance!

• reading of the sampling frequency of the NI9862

  Hi all

  I use a DAQ chassis with modules 9205 (analog input) and 9862 (NOR-XNET CAN).

  I have a program to synchronize the modules for acqustion based on the attached example. My question is how to determine the rate at which data comes the 9862?

  It seems to be double the rate of the 9205 when I set the sampling rate for the 9205 to 500 Hz.

  Is there a property node or a method that I can use to find the rate? I looked in the manual, and it gives no information.

  Thank you

  Griff

  griff32,

  Baud rate XNET CAN occur in your database. You can also check using a property node. In the example, in the XNET Session property node, you can develop, select the Interface > baud rate. You can do a right click on it and change it to read and son in an indicator.

  Alternatively, you can write to this property node to replace the transmission speed in the database. Baud rate must be compatible with the speed of your network. It also has a max of 1 mbit/s. If you want both to acquire the same amount of data, I would recommend changes in the rate of the analog input task or samples to read through.

• cwdsp. Sine wave is where the sampling rate?

  Hello

  According to the method above (CWDSP. Sine wave), the parameters are the following:

  (n, a, f, Phase)

  n As Variant - [Input] number of samples to generate.
  Amp as Variant - [Input] Amplitude of the signal that results.
  f As Variant - [Input] frequency of the signal resulting in standardized units of cycles/sample.
  The phase as a Variant - initial phase [output] in degrees of the generated signal. Output, the Phase is the phase of the next portion of the signal. Use this setting in the next call to this function to simulate a generator of continuous functions.

  We are not lack of sampling frequency?

  example:

  I want to generate the next sine-

  FREQ = 1 kHz

  sampling frequency = 10 kHz

  (Number of samples) block size = 1024

  Amp = 1

  How will you use this function for this signal?

  I think (but I'm not sure of it...) is: CWDSP. SineWave (1024, 1, 1/10, 0)

  There is an example: "power spectrum".  In this example, they do not mention the sampling frequency and the signal is generated as follows:

  CWDSP. SineWave (1024, 1, 0, 1000/1024)

  No mention of the sampling frequency.

  Thank you

  Hey Rafi,

  Both of your assertions are correct.  The frequency of de.1Hz at no time is the equivalent of what you would get from sampling equipment of a wave of 10 kHz to 1000 s/s; in both cases, you will see a cycle of the wave every 10 samples, as you are pointing out.

• DMM (NI 4070), how to correctly set AC Freq (bandwidth) by the sampling rate

  using a NI4070 multimeter and I see the max connection is 300 kHz by respect it.  But I don't understand how to set the min and max, acFrequency according to the sampling frequency or speed reading.

  6 1/2 digits resolution, the speed can vary from 0.25 s/s to 100 s/s and this range corresponds to a lower end on the connection (minimum acFreq) from 1 Hz to 400 Hz.

  (Q1a) - is the playback speed, controlled by the minimum setting of IviDmm_ConfigureACBandwidth?   or vice versa?

  Otherwise, I do not see how to control the rate of reading or the sampling frequency.   IviDmm_ConfigureMeasurement only allows you to control the range and resolution.

  (Q1b) - is there a way to directly control the sample rate (digitizer) or playback speed (dmm)?

  (T2) - the upper limit of the bandwidth of AC always seems to be at 300 kHz... is there still a reason to reduce this maximum value?

  (T3) - Finally, unlike the traditional niDmm function, the resolution via the IVI configuration should be passed as absolute value; does directly when number of digits and the beach?   For example if I want to 6 1/2 digit to 300V range, I guess that by the specifications that the resolution should be set at 0.001 V... followign, if I want 5 1/2 digits to 1V range, the resolution should be set to 0.00001 V?

  Hi Rjohnson,

  I'll try to answer your questions as best as I can:

  Q1A.  The ConfigurACBandwidth function is used by the driver OR DMM to calculate the good aperautre for the measure.  So yes, by adjusting your minimum frequency, you will affect your reading speed.

  Q1B.  Your reading rate will depend largely on your measuring cycle.  To get a fast measuring cycle, there are a few things that you can adjust.  You can programmatically control your time aperature, as well as your time to settle.

  Q2. I can't find a reason to change. This parameter is only used for error-checking and verifies that the value of
  This setting is less than the maximum frequency of the device.

  Q2B.  I think what you say is right, but I'll need to check on that - I'll let know you as soon as.

  Hope that helps.  "" "I would recommend checking the explanation of the Cycle of the DMM measurement in DMM help' devices ' NI 4070" DMM Measuments "DMM measurement Cycle.

• Change the sample DAQmx and Terminal configuration mode

  Hello

  I'm studying 'Timing and synchronization features of NOR-DAQmx' from the following link,.

  http://zone.NI.com/DevZone/CDA/tut/p/ID/4322

  Could someone tell me how to Figure 2, Terminal configuration entry in the part "DAQmx virtual channel creat? Shoud I double-click on the icon to change it? Or there is some way that I can show it in the block as the sample mode diagram in the DAQmx part?

  How can another question, in the DAQmx calendar part, I put "Continous Samples" here? It comes from the function palette? Thank you.

  Hi Oly,
  To make the configuration of senior year to enter the channel 'DAQmx create' you will need to create a constant or control over this VI either.  When you hover over a VI, as the VI "DAQmx Create Channel", you will notice that the dots appear around the edge of the square.  "" When you roll your mouse over these points, you mouse pointer will appear a coil of cable/wire how you can right click your mouse and select 'Create' constant ' or 'create' control '.  If you create a control, you have a user control in your front, where as if you create a constant, you will have a drop-down list in your block diagram.
   
  It goes the same for continuous samples, simply hover over the VI, right-click on the corresponding 'point' and select this option to create a constant.
   
  In case my instructions are unclear, that I have attached pictures of how to go about doing this, the first is to show 'points' I speak around the VI and the second picture shows the possibility to choose after you right-click on the point.
   
  Good programming!

• Digital filter on the sample clock 6601/6250

  Hello

  I use a PCI-6601 (Dev1) and the card PCI-6250 (Dev2) connected via a cable RTSI.

  I apply a PWM signal to the 6601 ctr0 (Dev1 / / PFI38) and activate the digital filtering (100 ns) on the respective task (measure of the period).

  I apply an analogue signal to AI0 map of 6250. As I am interested in a sample of analog measurement when the PWM signal changes from low to high, I put the clock sample of the AI task source ' Dev1 / / PFI38 "and the side assets of clock sample"Insurrection. "

  Everything works fine, but I have a question:

  The sample for the AI clock is the task the filtered PWM signal or not filtered PWM signal?

  Kind regards

  Udo

  Hi Udo,

  Great question!  Digital filters are actually not part of the subsystem of counter, but rather the line itself PFI.  So, if you have activated the digital filter for a specific line of the PFI, the signal that you route to any subsystem of the PFI line will have already crossed the filter.

  It's actually the workaround to the PFI filters on M-series / TIO DAQ devices when you are not using meter (materials of filtering on each PFI line but the DAQmx driver allows only the filtering part of duties of counter on these devices).

  I also wanted to emphasize that the 6250 itself has 2 onboard counters, then you could do the same thing using just the 6250 (unless you use more than 2 meters).  I hope this helps!

  Best regards

• Buffer the output AO, refresh rate is different from the sample clock frequency

  Hello

  I am an AO output in the buffer using a single channel. I have a stamp with a ripple of 200000 points with a triangular waves of a 1000pts each repeated 200 times. If I want a frequency of 1 Hz, I simply update this waveform 1000pts and if I wanted to 5 Hz, then 5000pts and so on. But there is some frequency that I won't be able to use like the refresh rate (the number of samples that I ask to update) is different from the sample clock frequency, which makes synchronization with the other difficult to trigger (incomplete cycle).  Frequency 3 Hz (update 3000pts), as (update 7000pts) 7, 6 Hz (update 6000pts), 9 (update 9000pts)... 11Hz at 15 Hz and is not valid in the sense that the refresh rate is different from the sample clock frequency. That makes a whole lot of inaccessible CONFIGURED!  Can someone tell me what determines the banned frequency?  Is this something to do with the material?

  concerning

  One thing you can try is to change the number of samples per cycle. This cannot give the precise frequency accurately, but can reduce the average error.

  120 Hz, the error is currently about 400 parts per million (ppm). The accuracy of the time base is 50 ppm, then this error is less than 10 times the inherent error due to the time base.

  Consider this configuration: the closest nominal sampling you rate, you can get is 120048 Hz (1000 samples per cycle at 120 Hz). If your buffer contains 1200 samples per cycle, 100 copies of it would produce 1 second of data to 120,048 Hz. But if the buffer contained an average of 1200,48 useful Samper by cycle, you get the exact frequency.  Of course getting 0.48 of a sample is delicate. But the kind of feasible. If you use 48 cycles in the 1201 samples per cycle and the cycles of 52 to 1,200 samples per cycle, the total number of samples per second = 120048. Average frequency will be exactly what you want. Instantly, the frequency is slightly higher or lower than the exact value.  By an alternation of 1200, 1201, 1200, 1201... 1201, 1200 100 cycles that the Jig is fast.  If you group all 1200s whole and all 1201 s frequency hopping may be more sensitive.  If this kind of jitter is acceptable depends strongly on what you do with the release.

  This technique is used in some systems of frequency synthesizer.

• How to specify the sampling frequency? Must use "measurement & Automation Explorer '?

  I use to measure the input current analog OR cDAQ-9171 (chassis only location USB) and NOR-9207. I have 2010 NOR-installed DAQmx and LabVIEW.

  How can I specify the sampling frequency?

  If I use M & A Explorer to create the task, I can specify the flow rate (Hz) on the Configuration tab-> sync settings.

  For the acquisition of data NOR, it is mandatory to use M & A exploring?

  If I don't want to use M & A Explorer, how can I specify the rate (Hz)?

  Hello

  You can specify the sampling frequency with "DAQmx Timing.vi" located in the function palette DAQmx (read context-sensitive help on how to use wisely).

  You do not have to use M & A exploring (MAX) to create a task.

  A simple and quick way is to use DAQ Assistant (same configuration as in MAX) to configure your measurement.

  Another is to use blocks of DAQmx function to manually build your application code.

  In my experience Assistant DAQ is ideal for simple tasks (one measure), with regard to the more complex measures (synchronized the analog and digital inputs).

  I tend to use function blocks because they give you more freedom about code execution.

  Note: You can also build DAQmx code from a wizard configured DAQ task.
