• Trend ServerProtect Real Time Scan kills Performance

  I've just virtualized a Windows 2003/Citrix Presentation Server 4.5 server on a host of vSphere with a NetApp FAS2020 using NAS as the data store where the virtual machine is stored.  There is no other guests of the VM on the host for the moment and the NetApp is not still used for other purposes (i.e. nothing should be taxing the material).  I found that ServerProtect V5.58 time real scan running on the Citrix server limits the CPU at a constant 100% once about 8 users are connected.  If I disable the real-time scanning, everything goes back to normal.

  Clearly, I must be able to protect users from malicious software Citrix sessions.  What is the best way to achieve this with Citrix/Terminal Server VMware?

  Someone at - it a version more recent ServerProtect or even OfficeScan running successfully within Citrix/Terminal Services hosted on VMware?

  Thank you

  Hello

  Moved to the Security Forum.

  Reinstall the trend after a P2V could help but maybe not.

  Trend also made programs specifically for virtualization and vSphere that will do A / V of the analyses using the API that will not also drastically affect performance vStorage, it's something to look into. Maybe but not 'real time' will allow better overall analysis.

• can not turn on real-time scanning 0x8000705b4 error code

  got fed up with Mcafee so I removed the product with the programs and features and then used their cleaning cleaning tool Development than anything flying over. When I try to turn on real-time scanning, I get the 0x8000705b4 error code.  The defender service is running.  I have windows 8.

  I decided to solve the problem by setting another disorder, that I'd been procrastinating. I've migrated my operating system on an SSD and could not be upgraded to win 8.1. A little research revealed that I was not the only 1 with this disorder.  In any case, a clean install of win 8.0 followed to upgrade to win the 8.1 and the problem disappeared.  Thanks for your help.

• difference between the real time module and module fpga

  Hi experts,

  I was wondering if someone could tell me the difference between the FPGA and the module in real time (in short).

  My understanding is that the FPGA module facilitates code LV that can then be designed for the specific advice of RIO, I have used this a bit in the past.

  The real time module, I'm a little more unsure about, all I know is that it allows the creation of a 'real time' i.e. deterministic environment.

  My request is this: I wish I had several control loops running on two tables of RIO, with the host PC mainly used for recording data and user interface. I see that I have no need of RT on the host (Win XP should be good).

  Do I need the RT module?

  You are right.  In the scenario you describe, you won't need to LabVIEW RT. LabVIEW RT is used to create a deterministic execution on specific targets for intel such as the PXI-8106 and PXI-8108.  You can still use strings and floating point on RT.

• Subtract the model image of a real-time video and image/video subtracted from output

  Hi all

  I have a case in which I need to acuiqre a video (of circular loop) to a camera (which I am able to do with the vision development module in avi format) and subtract the model standard (for loop) image of him and display the output for each frame subtraction. The subtraction will tell me how much movement there was in the loop in real time. Is it possible to do?

  I donot want to save any image or video, just want to show the subtraction of real time to the user

  Hello AnkitG,

  Subtract the IMAQ VI removes one image from another or a constant. You can then view the removal from the user or save the images if necessary. Here a link to the reference IMAQ subtract VI.

• Real-time display and receive data from txt files

  Hello

  I am creating a Flash component and I'm doing an editor for him.

  The component itself receives all its parameters to a .txt file.  The editor is a form of reading/record, that initially loads the settings in the form fields, then replace the .txt file when the user presses submit.  Then, you update the component on any Internet site, you have to see the changes.  I plan also to import the swf of the component in the editor.

  Here is the php code I found to help me will do:

  <? PHP
  Enter the data in the table of $_POST
  $title = $_POST ["title"];
  $comments = $_POST ['comment'];
  $image = $_POST ['image'];
  Make a chain in a Flash format
  $toSave = "title =". "." $title. "& comments = '. '. $comments. "& image =". " $image;
  Open a file in write mode
  $fp = fopen ("anastasio.txt", "w");
  If (fwrite ($fp, $toSave)) echo "write = Ok;
  else echo "write error";
  fclose ($FP);
  ? >

  If I have correctly configured as3 to send and receive on the fields of form a dozen as an experiment.

  What I want to do now is to do more in real time, so that the changes are reflected in the component that the user types parameters in, rather than submit them htting and then having to refresh the component swf to see the changes.

  What is a good way to go about this?

  Thanks for your help on this one.

  Shaun

  AS3 textfields have a change event that is sent when a textfield text changes.  You can use it to update your text file.  refresh a component in another swf file will require you to use the localconnection class to communicate between the two rulers.

• RAC, listener to scan and firewall

  Hello

  We have a 11.2.0.3.8 SE RAC on linux 6.5 server two oracle. An instance must be accessiable by clients behind one firewall, either case, not. My solution is a second local listener with a different port. If you know another way, I'll be happy to hear, thank you.

  Best regards

  Thomas

  There are a number of considerations.

  The TNS connect string wants to connect to a service. This service can have multiple points of termination (supported by a number of bodies and registered with the listener by these bodies).

  You can connect to server1 public static IP, port 1521 and ask a connection service dbname1. But as dbname1 was recorded by all RAC servers and that the listener also has port 1527 as tcp listener endpoint and addresses are used as a number of IP static and virtual - your client could very well be redirected by the database instance listener 5 Server5, via a virtual IP address and the port 1527.

  If a connection request by the client on port 1521 to server1, doesn't mean that's where the real Oracle client-server session will end.

  If you are planning that the static tcp, the listener port should only be listening on a single port. I've seen listeners set up for multiple ports (1521 and 1527), with only one port opened through a firewall, with intermittent connectivity - result as any other connection get a redirect to the other port.

  The listener also distributes host names (assuming a good config listener.ora and network) when the redirection of a client connection.  For example you connecting host server1 name and get a redirect to Server5.

  If server1 is only accessible IP the current network (firewall, etc.), we can address the redirect on the client - in solving all host names passed by the listener to the IP address that works. For example local hosts file customer resolve server1 Server5and server1-vip to Server5-vip, this unique IP to work.

  If you want a client to select a specific instance of the CARS to connect to (or force connections to a single specific instance), you can use the service_name parameter. This is by default the value db name and db-domain on multiple RAC instances. This means that all levels of RAC record the same service with listeners. Allowing a connection of client for this service will be handled by any instance RAC (high availability, etc.).

  You can also add a unique service for this instance RAC instance RAC. This service will be so registered by a single instance of the FCAC and the client connections requesting this service (connection via SCAN or other listeners CARS), will always get redirected to this forum.

  In the scenario you described, I would not use a secondary headset. I would like to use a unique service name to limit client connections to one specific instance of the CAR and the hostname/IP server. I would not use several ports tcp as listener endpoints. And then ask this IP and port to be open on the firewall and giving that service name to the clients that connect through the firewall.

• Real-time, semaphores and Subvi

  Hello

  We use a handful of semaphores in our application of Realtime (2015) on a cRIO.  For cleanliness, I wanted to encapsulate each semaphore in their own VI.  When I did the semaphores didn't work properly.  I feel like it is fundamentals of labview which it reveals, and I need to know!

  So, below, is more or less the standard semaphore HelloWorld program - it's similar to the Labview Semaphore.vi Simple example.  'Digital' and 'Digital Slow' indicators increase more or less increments.

  

  The next thing I did was create a VI load functions of semaphore to acquire and release, as shown below.  You can ask "what's the point?  In my desired version of VI the semaphore would not control well, rather "prevail" within the VI (and avoid passing the semaphore throughout our program).  For this display (and test) I wanted to make things as simple as possible so that I spend in the semaphore.  Notice that the VI is not reentrant, making simple threaded.

  

  Using the VI in the test program is shown below (in a disabled state)

  

  It does not work!  I followed the program and acquiring works (a product thread and the other blocks), but will block the release (on the thread of the "Acquis").  Look in the Labview Release Semaphore.vi code I don't see a reason it would block (I can't add the points stop or probes to this code).

  Can someone make sense this for me?

  Thank you

  Steve

  I made this error even with a motor of Action using queues.

  Your problem is that only 1 appeal to the Subvi can arrive on time.  If you have a thread the semaphore by the Subvi.  Meanwhile, the other thread is waiting to be able to use the Subvi to acquire the semaphore so.  If the first thread finishes the consecutively Subvi and fact its task.  Meanwhile the other thread is blocked in the Subvi waiting for the semaphore to be released.  Now the first thread is made his duty and try to go to the Subvi to release the semaphore, but this is impossible since the second thread always uses the Subvi.  If the second thread blocks the first thread to use the Subvi and the first thread blocks the second thread by being not able to release the semaphore.  You are in a bind.

  Why do you use semaphores anyway?  I found that they are rarely needed in a properly modulated code.

• cRIO - creation and deployment of real-time independent startup application troubleshooting

  I use cRIO-9024 with a chassis 9112 for a control system. I use LV2011 SP1. When you run the system in development mode (by pressing the run button), everything seems to work properly. When the autonomous real-time construction and running in startup application, something stops working.

  In order to know if the application is running or not, I toggle the user LED on the cRIO using this code:

  

  When I turn off all the code in the main VI except this loop, the application deploys and runs at startup without problem (the LED flashes). I then add progressively more loops that I want to run (by disabling the code less and less), and the problem seems to be in the open FPGA VI reference block. If I disable this block, the slopes of autonomous real-time application (I guess the error 63195, handful of peripheral communication not valid, will spread along the line, but I know that the app works because the LED flashes).

  

  I tried several configurations for this block open FPGA VI and mixed results. For example, if I set it up this way:

  

  The application in real-time to start runs with the reference block opened VI FPGA active but work stoppages as soon as I turn on a code that makes use of this reference in the subVIs .

  Someone at - it an idea of what could go wrong? I have explored the messages thrown by cRIO at startup but can not see the error messages (in fact, the console output is the same when I managed to deploy an application that is running (by disabling the code). I also tried to explore the error logs (via right click on target Utilities > view error log) but cannot decrypt any useful info on their part.

  

  Any ideas will be greatly appreciated.

  Hi kkguner,

  My problem is that the code runs (apparently) ok in development mode, but it seems that, when it is deployed as a stand-alone application in real time, it does not at all. As I was not able to get messages through to watch the console output when restarting my cRIO or explore the Project Explorer error logs or error, I can only imagine what is happening.

  I feel that QFang suggestions go in the right direction, but I've yet to be able to determine the exact cause and the solution of the problem.

  The solution I set it with has been to deploy my application as a source with a start VI distribution instead of as a stand-alone application in real time. You can try this option.

  What I could try when I have some time is to clean my system from LV (whether in mass compilation or by reinstalling completely). I tried a massive compilation of vi.lib and I got a good amount of (UN) insanities, the wrong screws and several other unfortunate messages.

  kkguner, let us know what you discover in your inquiry, or if none of the suggestions solves your problem.

  Thank you QFang and xseadog for your help. Best regards!

• Algorithm of PID in 'PID and Fuzzy Logic Toolkit' and 'real time Module ".

  Hi all

  I am recently using LabVIEW 2011 and 2011 real time Module. My application requires the PID control.

  Now, I have a problem. In the manual for "And Fuzzy Logic Toolkit PID", Chapter 2 "algorithm PID" it indicates non-interactive algorithm (also called the ideal algorithm, Standard or ISA) be used in all the screws of PID in the Toolbox. It seems that Yes from source code. However, in Chapter 3, "Using the PID software" arrays of calculation of PID parameters based on method of Ziegler-Nichols, which was developed for the interactive algorithm (also called the series, the real classic algorithm). D action has been included in the scheme of control, the settings may be different for the two algorithms. In fact, Cohen Coons and adjustment PID Lambda rules can be used for the algorithm used by the box tool with no conversion.

  In addition, there is a PID function block comes with the real time Module, and I know not what PID algorithm it uses. Can someone help me?

  Thank you in advance.

  Su

  In the "and Fuzzy Logic PID Toolkit, we use the University structure to implement all algorithms. Tuning techniques we show on the manual to express the original work and we try to keep the same as you would look at the literature. However, in our implementation of autotuning internally converted to the structure used by our algorithms to keep compatibility with our own implementation.

  If you use an external source, you can use the Conversion.vi of Structure PID to change University, parallel or series of parameters in one used by our algorithm.

  The PID included with the real time module is a 'copy' of our algorithm, and they have the same settings and behavior. The only advantage to use this function block, you have access to the parameters through variables.

  Hope this helps...

• Deployment of local variables shared on a real-time target

  Hello everyone, once again

  I read more posts and knowledge base articles about this topic than I can count at this point, and I'm scared, I'm still not clear on exactly how it works, and I hope that someone can delete it for me, if it is to earn themselves some laurels more.

  I have a project with a real-time quote and the other Windows.  They shared communication via network-published variables.  The real-time part also uses shared single process variables to communicate between the loops.  I have the intention of all 3 libraries of shared variables (Windows-> RT, RT-> Windows and RT Local) to be hosted on RT target for reliability.  Real-time executable must start at startup and run even if side Windows is not started (on the side of Windows is optional).

  I realized that real-time executable will not start the variable engine shared and/or deploy itself shared variables.  I also read that I can't deploy the shared variables programmatically from the side of RT.  This leaves only two options that I know of:

  (1) their deployment programmatically in Windows-side program.

  (2) deploying the shared variables on the target RT manually via the project in the LabVIEW development environment, and

  About option 1, as I said running Windows is supposed to be optional, so you have to run a program on the Windows side before the side RT will work is highly undesirable.  Moreover, even if I do a little "Deploy shared variable" application that runs at Windows startup, I can't guarantee that it will work before start of the side RT executable will run.  In this case, the executable file RT will fail due to not having the variable engine shared running?  If so, and side Windows, and then starts the engine / deploys the shared variables, the side RT begins to work automatically?  If not, is it possible to trigger this restart of the Windows startup application side?

  Also, I just read everything and tried the option to build to deploy variables shared in the application of the side Windows.  Not only that my RT shared Local Library variables not listed as an option (given that the application of the side Windows does refer to it in all for obvious reasons), but when it deployed two other libraries at startup, the program side of RT (which was running in the development environment) stopped.  I'm not positive that would happen even if he was running like a real executable file, but it is certainly enough to make me nervous.  I assumed that the library is not listed may be resolved by including a variable network-a published in the local library of RT and including the app side Windows.

  About option 2, I don't understand how I'm supposed to deploy my libraries shared variables without stopping the execution of the startup on the target real-time application.  Once I did, the only way to restart the application of the RT is to restart the computer RT, correct?  In this case, I just undid all the interest to deploy the shared variable libraries?  Unless libraries remain deployed and variable motor shared running even after restarting the computer of RT, which would solve the problem I guess.  Certainly, I would like to know if this is the case.

  However, option 2 is complicated by the fact that when I manually right-click on any of my shared variables libraries and select "Deploy" or 'Deploy all', libraries still do not appear in the Manager of the distributed systems, even after clicking Refresh several times, on the local system or the target system.  The only thing that shows up, on both sides, is the Group of 'System', with FieldPoint, etc. in it.  The same is true when I run my application in real-time in the development environment, even if the shared variables are clearly working, as I mentioned earlier.

  So, if you have done so far through this mammoth post, thanks!  I have three main questions:

  (1) are that all my descriptions above correct in what concerns the variables how work sharing?

  (2) what is the best way to meet the requirements I have described above for my project?

  (3) why shared variables libraries not appearing in my manager of distributed systems?

  Thanks for any help you can give on any of these three questions!

  -Joe

  1. Yes, as soon as you deploy the project the NSV is tranactional.  EVS is loaded by MAX when you configure the RT target and begin to operate as part of the boot sequence.

  2. you can see anything on your target rt in the DSM?

  3. Yes, NSV and EVS are persistent resets.

• THUMBNAILS VIDEO DISAPPEARED AFTER THE INSTALLATION OF REAL TIME

  After you have installed the latest version of "Real Time Player" which is an upgrade to 'Real Player of cloud', all the video thumbnails are not visible on a single computer. 'Real time' has been installed on two computers with almost identical Windows 7 Home Premium and processors within minutes of each other.  A computer kept all video thumbnails while the other did not. So far I have uninstalled and reinstalled in real time, uninstalled and reinstalled Real Cloud, but still no thumbnail previews. I also tried the verification of the method 'display only the photos '.  I'm looking for someone who's hands are successful on empirical knowledge for this question. Thank you.

  Stanley,

  Here's a recent update on my original investigation.

  After an upgrade of RealTimes Player RealPlayer Cloud download failed to produce thousands of miniature video generated by RealPlayer cloud, I immediately started looking for answers in this forum of Microsoft.

  I have two new computers HP here on my desk. A computer has received the RealTimes Player download and continued to display thumbnails. This is the second HP computer that the thumbnails are not visible.

  Several answers to this problem repeated the same methods. I tried these methods more than once and still no pictures. Then I took action on your message and another someone from Real.com contact Real.com. The only way to contact Real.com was by email on their website. I sent them an email describing the problem. Now, it's my experience that Real.com has even good tech support for free download of RealPlayer. Their first suggestions were identical to the information I received Microsoft community. Following is a concise list of end to end on how I solved the problem before Real.com phoned for help, which may have included access remotely:

  (1) download the RealTimes Player "new" (that's their latest version of RealPlayer cloud;) I know now I should have stayed with cloud of RealPlayer).

  (2) a computer downloaded without any problems, while the second computer lost all thumbnails.

  (3) I contact Microsoft Community to get answers.

  (4) community Microsoft sends answers, including and meet someone from Real.com.

  (5) none of the above gives a solution.

  (6) I am Real.com e-mail for a few days through their website with no solutions.

  (7) I have uninstall RealTimes Player on both computers.

  (7) I call the HP Technical Support to make a 'system restore' on computers.

  (8) after the "System Restore", I reinstall MSE, and all thumbnails are restored on the computer and three external hard drives. All thumbnails are Windows Media files. None of the hundreds of RealPlayer Cloud files can be opened.

  (9) Real.com offers to call me at one time that I choose, which may include remote access to my computer.

  (10) I answer Real.com Friday that a time to call will be the following Monday.

  (11) the following Monday at the appointed hour, Real.com has not called. I waited 30-40 minutes. While I was waiting, I've been on the Real.com site read comments in the section "RealPlayer/RealPlayerCloud. In a response from Real.com Tech to one of the speakers, they gave to this speaker a link to download RealPlayer Cloud. I took a chance with this link and downloaded RealPlayer Cloud in my computer, not only did the Windows Media thumbnails remain, but I was able to play all audio Real Player and video files, and the "Download this video" button a drop down of RealPlayer has been restored. I turned so my attention on the other computer, clicked on a download link that says Cloud RealPlayer on Real.com Web site, and when the download is complete, it was the new RealTimes Player again, not RealPlayer Cloud. But, all right. All thumbnails are back in this computer while being able to play all Real Player files. Now, a computer has the 'new' RealTimes Player and the other has the original cloud of RealPlayer.

  (12) after all this was over, and two computers were back to normal, the representative of Real.com called (almost two hours late; he was on another call that lasted longer than normal). I explained that while you wait for him to call, I reinstalled Real Player on both computers and everything was back to normal. I mentioned reinstalling RealPlayer cloud on the other computer and it recommended that all was well under way, for whatever. I agree with you.

  (13) since the call of the representative, Real.com has sent me a couple of times and told me they were happy that the problem has been resolved and do not hesitate to contact them for any future problems. I asked for a download link for RealPlayer cloud which they sent a warning that they were not certain if the link has an expiration date, but to contact them for any problems or questions.

  (14) although I have Google Chrome on a single computer, all my audio/video download through RealPlayer Cloud/RealTimes drive is via Internet Explorer, not Google Chrome. I prefer the drop-down menu "Download this video" button at the edge of the screen in Internet Archive rather than the barely visible button at the top to the center of the page in Google Chrome.

  Microsoft 15 community) thanks and Real.com.

  (16) a lesson learned. When everything works fine, why switch?
