• Flash video does not not in the opera, specific to one machine - why?

  ice http://www.eWeek.com/c/a/IT-Management/using-Predictive-Analytics-to-Improve-Customer-serv /? KC = STNL06022011STR7

  Have upgraded to the latest version of Flash (no - AX and AX versions) but I can't get the video at this link to load or display - he is not alone as there are others that won't load or play, but it is not a universal disability because the wobbly combination of machine and browser will play the confirmation Flash animation to Adobe and videos of other correct site site.  At first, I thought, it might be a problem with the limited storage (10 KB) limit in the Flash Player settings, but I changed the two worldwide and 100 KB of the site settings and tried again (without, then with a reboot), but without success.

  This may reflect an underlying BONE problem for this Win XP Pro SP3 machine, because it will not correctly run or view more Flash videos in my favorite browser primary/opera (v11.11 b2109).  However, I can view them on the same machine in FF or IE without any problem and on other machines XP Pro SP3 (or Vista/Win7) to the opera, so so the problem is specific to that one machine and the browser.  I posted a thread on this subject in opera forums, but once I had reduced the issue decided that better post here as well.  This issue started to happen after a previous update of Flash, and I thought that maybe the last update can fix the problem in a complete uninstall (no - AX and AX versions) and restart the computer before installing the new versions out this weekend.  No, so I hope that there will be a few wizard (s) lurking around here who might be able to guide me in diagnosing and fixing problems...  Thanks for the insight and attention in advance.

  Hi, thanks. This extension "noads" most likely is the problem. Try to disable it because it is probably blocking Flash content.

  Thank you

• cDAQ-9178 & NI 9401 - ASM: incremental Rotary encoder works is not beyond a certain frequency

  I use a chassis with a NI 9401 DIO module 9178 cDAQ.  I'm trying to convert the output of a rotary incremental encoder ASM (in radians) to rpm.

  Sensing head (PMIS4-20-50-240kHz-TTL24V-Z0-2M-S)

  Snap ring (PMIR7N-20-50-M-20)

  The encoder outputs 2500 pulses per rev (output 5V TTL).  The maximum speed which will see the encoder is 2800 rpm, which is equivalent to 2800 RPM * 2500ppr/60 = 116,667.67 Hz in terms of frequency.

  Since the NI 9401 of the operations specifications:

  Maximum of the input signal switching frequency by the number of input channels, by channel

  8 input channels... 9 MHz
  4 input channels... 16 MHz
  2 input channels... 30 MHz

  I use only 1 channel, so I'm assuming that the 9401 should be more than capable of handling the 116kHz which the ASM encoder is spit.

  Everything works fine until about 2100 RPM (~ 87, 500 Hz) but then I begin to see a drop in rpm, followed by a flattened behavior, then a slight increase. But never more than 2100 RPM.  Our test unit is inspected for other reasons at the moment so I can't produce a plot of the behavior (I can reupload later).  I think this must be a matter of aliasing with the meter or something of the sort.  I have a digital filter set in place with a minimum of 4.0E pulse width - 6.  It is two times smaller than the width of minimum pulse at a frequency of 116kHz (0.0000085714).  I don't think this should have an impact on the calculation.

  Any suggestions? This value of RPM is essential to our application.

  Thanks in advance,

  A 116 kHz frequency, the period is ~8.57 us, but the pulse width half duty cycle of 50%.  Ascent/descent time factor, and it is quite possible that 4 US is too long for your encoder signal.

  The shape of this graph supports this theory, if we consider that there is variation in the exact pulse of each encoder pulse width.  The shortest pulse is ignored when the filter starts to kick in, and the speed of ROTATION increases pulses longer and longer are ignored then as well.

  Try to decrease the minimum pulse of digital filter (US 2 or even 1 US) width and see how it goes.

• How to find the sql queries executed in one day with the sql and runtime text

  Hi Experts,

  Please tell me the sql query to find out the queries executed on a particular day and the runtime and the sql text of the query.

  Please reply urgent.

  Thanks in advance

  Database instance 'A' may have run 100 SQL queries today.  As for the instance of database 'B' could have exploited queries SQL 1 million today.  Instance of database 'B' to 'keep' the 1 million SQL statements - in memory or on disk do you expect?  Of course not.  There the age or flush or invalidate memory SQL statements.  He can't keep them on the disk (imagine running a completely different set of 1.2million SQL statements tomorrow and 1.3 the next day).

  AWR and StatsPack can make counts the number of "n" top of the page ("n" default to 30) SQL statements which are still present in the cache of the library (not years, rinsed, invalidated) when a snapshot was taken.  They can't declare "all" SQL statements.

  To return to your needs.  WHY do you need all the SQL statements?  Or are there only certain operations specific SQL would you be interested?  Could they have been treated by allowing audit (for example, UPDATE and DELETE with EXTENDED verification instructions)?

  vSphere-wssdk-ui and vsphere-wssdk-provider

  Description

  This example shows how to use the vSphere Web Services SDK (WSSDK) on the side server to access the data of vCenter that you might not be able to get with the models presented before data request. More generally the WSSDK API allows access to objects managed vSphere that can be used to manage, monitor and control the lifecycle of all the components of the virtual infrastructure operations (vms, data centers, data warehouses, networks, etc.). This example shows how to retrieve the properties of the object, but the same WSSDK could be used to implement the operations specific vCenter in your plugin.

  Its use

  This example uses WSSDK library vim25.jar of the VMware, located in/vsphereviews/vsphere-wssdk-provider/lib. For the blank server load this library during development, it must be copied to the/server/repository/usr directory, see first how to use libraries third 3rd for more details. (The other library, commons-logging - 1.1.1.jar is already part of the repository Virgo.)

• This disc contains a "UDF" file system and requires an operating system that supports the ISO-13346 "UDF" file system specification.

  I've seen other posts on this topic. Nothing seems to work, so I thought I would explain my situation.

  The machine is new. Win7 64 bit company. The problem I see is that I try to load some versions of Visual Studio on the new machine. However, none of the discs auto-run using my local internal DVD drive. They all have a Readme file with the message "this disc contains a"UDF"file system and requires an operating system that supports the ISO-13346"UDF"file system specification."

  I know that the discs are good, I used the on my old machine, and I can always use them on other machines I tested.

  The real kicker here is that I can plug an external USB DVD drive... and then the local drive starts to read the installation discs! It's like making this action allows something else in the machine.

  Also, I even restarted the machine mode of diagnosis (without external DVD drive attached)... and restart, the drive would read the installation discs. BUT when I do a full stop and then turn on the machine upward, the local drive gives me the same readme file. Again, it is as if something gets activated, and then reset to a complete stop.

  I am at a loss of what to check then. Real head-scratcher, because I know the drive works and the machine can recognize the drive and even read installation discs.

  I do not have the applications installed on the machine of DVD burning, so I don't think there is a conflict.

  Any suggestions are welcome.

  Thanks in advance!

• Hardware timed CI/CO, operation of PCI, I / AO with specific execution order

  Hi all

  I work with a USB-6361 NI data acquisition hardware and I'm writing a LabView 2011 program which sends a signal to my output device and reads several values of various measuring devices. I have a ramp voltage signal (in a table format) and I need to sequentially send the elements of this array on my AO device with very precise timing (ideally timed material). As soon as the value is written to the device of the AO, I need my tasks HERE and CI to record all available data and my task to send a single impulse before the next array element is sent to the device AO. All this needs very precisely timed such that if I perform a measurement on 1000 points in my table of ramp with a timing of 1000 Hz, the program will have exactly 1 sec. to run (less overloading caused in initialization and closing tasks) and produce a table of data consisting of 1000 steps of AI and CI. I had initially tried to achieve this by using a structure of sequence within a timed loop software, but because I won't get into multiple channels of Amnesty International and CI and tables of data, this has proved to be excessively slow. The other danger that I fear I could run is the case in which the LabView program runs more slowly than the process of acquisition data itself, thus causing data to write to the buffer and the measures being lost.

  I didn't spend a lot of time working with the procedures, timing and synchronization, so I apologize if this is a rather naïve question - I'm having trouble reconciling restrict them inherent software and order of execution with the hardware timing. What is the best way to solve this problem? I can only think of two reasonable approaches to the problem:

  (1) should I try to trigger my CI tasks and HAVE run on the completion of the task of the AO (and if so, how)?

  (2) I have the CI and tasks run on a separate clock with a start delay initial light as to compensate for these tasks if they occur reliable after that each value AO is sent to my device?

  Finally, I build an identical for a real-time embedded controller program of SMU-8100. The approach will be different in this case?

  Thanks in advance for your answer.

  I can give you an overview of the steps you'll need, but be ready to spend experiment a little time and some of these individual pieces of troubleshooting before you put them all together.

  First of all, a X-series 63xx allows all you need to accomplish a very precise synchronization in hardware.  When you then switch to a real-time controller, you must include an X-series device in the chassis to maintain this capacity of equipment.

  Second, 1 kHz is not yet a challenge to LabVIEW to catch up with your hardware, even with powered lower RT controller.  You just need to program the DAQmx tasks to let the hardware & driver do most of the work.

  1. I would dedicate a counter of the 6361 to generate the clock shared for other DAQmx tasks.  I tend to create a clock and operating cycle of 90-95% for this type of application of stimulus / response to the response time & maximum stabilization.  Generate the stimulus at the cutting edge of the clock and gain response data on the edge of leak - before the next sample of stimulus.  Call it the task of the clock.

  2 set up a buffered AO task that uses the output of clock as the sample clock. Configure the polarity to be sensitive to the cutting edge (usually, this will be a rising edge).   Start the task AO * before * starting the task of the clock.

  3 configure tasks HERE and CI to use the output of clock as their clocks in the sample.  Configure the polarity to be sensitive at the trailing edge.  Start tasks I and CI * before * starting the task of the clock.

  4. the output pulse should be a task of meter output, configured to generate a single pulse redeclenchables.  Configure it to use the leading edge of the clock as the trigger signal output.  Set the time of 'low' and the 'initial period' to equal precision<1 msec="" delay="" you="" want="" to="" make="" sure="" that="" you="" get="" the="" same="" timing="" on="" every="" trigger.=""  be="" sure="" the="" high="" time="" allows="" the="" full="" pulse="" to="" fit="" within your="" clock="">

  5 examine the "producer-consumer" model so that you can separate your data from your CQI data processing.  You should stream to file continuous rather than it accumulates in large networks.  Write speed of file can be unpredictable, this is why access to the file must be in a separate loop that acts as a data consumer that the loop of CQI data produced.  When you spend real time, assign a lower priority in the process of writing file.

• How to do a bitwise operation on a specific column in the database timesten

  Hello

  I need to do a bitwise operation and (&) operation on a column of data (whose datatype is NUMBER).

  If I do something like SELECT 1010 & COLUMN1 from TABLENAME;

  It will give the error: 'type 'NUMBER' not valid for operator 'BITAND' operand in expr data '.

  Anyboday can help me?

  Thanks in advance

  Concerning

  Arnaud

  NUMBER is floating point format. Bitwise operators apply only to INTEGER values. There are several ways to work around it...

  1. If the column in the database only stores integral values and then change its definition to NUMBER (n) (choose n) properly.

  2. change the select statement to SELECT 1010 & CAST (COLUMN1 AS TT_INTEGER) (or TT_BIGINT according to the maximum value if you tore in the column)

  3. change the column to a native integer TimesTen type as TT_INTEGER, TT_BIGINT etc. It uses less space and more efficient.

  The columns should * only * be defined as NUMBER (with no precision or scale) if they really need to have this flexibility. Always use an explicit precision (and which adapted as appropriate) because this saves memory and allows to avoid this kind of issue. Better yet, use whole native types TimesTen, wherever possible. They use less memory and provide superior performance to those of all variants of NUMBER.

• Order of operations

  What is the best order of operations to perform an upgrade of RAM, upgrade the OS and firmware update on a freshly wiped Macbook?

  The laptop in question is a Macbook version 7.1; 2.4 GHz; 250GB, 2x1GB RAM.

  I have the installation discs for Snow Leopard.

  I want to upgrade to El Capitan, and I would like to install 16 GB of RAM (2X8GB), I understand that this model can accept 16BG despite the specs from Apple.

  The System Profiler indicates that the firmware is not the latest version, which is believe is necessary for the 16 GB of RAM to work.

  To update the firmware, I would need to install it (temporarily) Snow Leopard, correct? And then should I upgrade the RAM, then the OS? Or is there a better order?

  Thanks for any idea.

  a. install the original OS first to see if that works correctly.

  b. then update the firmware, and it should work correctly after that too.

  c. now you can go after your wishes, without slipping questions with you:

  install more RAM using 2x8GB modules of the correct specifications (PC3-8500 (1066 MHz) of 204-pin DDR3 SO-DIMM) have a good brand, Crucial research or OWC.

  Use the mac and see if everything is still OK.

  4. all applications you want to use to ensure compatibility with ElCapitan 10.11.6 research:

  Search developer sites, a general site that helps (not always) is roaringapps.com

  5. check the operation of your Apple ID.

  6. download ElCapitan since the Appstore. You can make a bootable stick with Setup on this topic, if you have a backup before installing ElCapitan in the Applications folder. Then install ElCapitan and enjoy.
