• understanding DBMS_RESOURCE_MANAGER. Output CALIBRATE_IO

  Hi all

  on 11.2.0.3

  I am trying to understand DBMS_RESOURCE_MANAGER. CALIBRATE_IO. So I ran:

  SQL > SET SERVEROUTPUT ON

  SQL > DECLARE

  2 lat INTEGER;

  ARE 3 Ops / s WHOLE;

  4 Mbit/s INTEGER;

  5 BEGIN

  6 DBMS_RESOURCE_MANAGER. CALIBRATE_IO (< RECORD >, < MAX_LATENCY >, IOPS / s, Mbit/s, lat);

  DBMS_RESOURCE_MANAGER 7. CALIBRATE_IO (2, 10, Ops ARE / s, Mbit/s, lat);

  8

  9 DBMS_OUTPUT. Put_line ('max_iops =' |) ARE OPS / s);

  10 DBMS_OUTPUT. Put_line ("latency time = ' |") LAT);

  11 dbms_output.put_line ('max_mbps =' |) Mbit/s);

  12 end;

  13.

  And he gives:

  max_iops = 86

  latency = 10

  max_mbps = 47

  PL/SQL procedure successfully completed.

  This what should I understand max_iops = 86; latency = 10; max_mbps = 47?

  They are good? They are bad? How to improve?

  I have reviewed the following:

• 11.2 DBMS_RESOURCE_MANAGER. CALIBRATE_IO

  Dear experts!
  
  We use oracle 11.2 standard edition on the windows platform.
  
  When I start the following procedure:
  
  SET SERVEROUTPUT ON
  DECLARE
  LAT INTEGER;
  ARE OPS / s WHOLE;
  Mbps INTEGER;
  BEGIN
  DBMS_RESOURCE_MANAGER. CALIBRATE_IO (1, 20, Ops ARE / s, Mbit/s, lat);
  DBMS_OUTPUT. Put_line ('max_iops =' |) ARE OPS / s);
  DBMS_OUTPUT. Put_line ("latency time = ' |") LAT);
  dbms_output.put_line ('max_mbps =' |) Mbit/s);
  end;
  /
  
  I get the result:
  
  max_iops = 41
  latency = 23
  max_mbps = 28
  
  Which tells me the new io calibration function on? How can I use these values for the tuning of my database? For example, change the spfile settings.
  
  Thank you
  Markus

  No, the results are not used by the optimizer to do this, you use DBMS_STATS. GATHER_SYSTEM_STATS.

  with calibrate_io you just measure the IO subsystem. you may have a requirement of (x iops) for a new database. then, you set up the system and check if the conditions are met.

  Macarius,

  Because this seems to be not just a school problem, but also a review, I'm not very accurate so that I don't do your work for you.

  Your program can meet the required specifications.  She doesn't have a lot of understanding the power of LabVIEW.  The documentation is non-existent. Style leave much to be desired.

  Depending on what you are supposed to have learned, I would give it a passing beam but low grade.  It could be planning a lot with relatively little effort.

• "The device has changed and no output channel is present. Open Audio hardware preferences? »

  Hello

  I installed an infusion of SSD and fresh install of Windows 7 64-bit, including the installation of Adobe CC with premiere pro and other related applications. My audio works fine, I have a portable speaker connected to the back of the audio 'line in the green plug' at the back of my office, have not had any problems with her.

  However when opening Adobe PP for the first time I get the message "the device has changed and no output channel is present. You want to open the Audio hardware preferences. At the opening of the entry default preference reads "no devices available (does not). I was unable to change the value by default using the box entrance, but was able to change the default output. I changed the default output to ' speakers (device 2-high definition audio) and after that I got an error that read "sorry a serious error has occurred which caused Adobe PP stopped." We will try to save your work)".

  Is anyone able to help with this, I don't know how to set up the audio setting is all new to me. Also do not know why this has happened given my audio works fine in any other program that I use on my pc. Any help from an expert on this forum would be greatly appreciated. Cheers, Joel.

  

  My first guess is to check and possibly update the audio driver.

• Satellite L650 speakers and sound output stopped working

  Hello

  The sound in my L650 just stopped working all of a sudden. It was ok and then nothing.

  When connecting to the headphones, I can't hear a sound of crackling, that maintains the same volume regardless of the volume of system being 100% or mute.
  I don't have any other way to test audio output (no cables hdmi or USB speakers).

  Nothing has been installed recently. The drivers are up to date. Reboot didn't solve it. Uninstallation and reinstallation of its controller either.

  Everything looks fine on the part of the treatment (equalizer and its move from bars).

• Synchronization of analog and digital output with the external sample clock

  Hello

  First of all sorry for my English, I will try to explain what I want to do.

  I want my PCIe-6321 to send two custom signals (modification sawtooths) on a mirror controller. I would also like to generate output with my card at the beginning of each tooth of saw. Everything must be synchronized with an external k-clock signal of 100 kHz. The idea is that whenever the PCI receives a trigger to external clock, it sends two analog output voltages and when he received 1024 clock ticks it will also send a pic of triggering TTL. What I do is first prepare the map and after that in a loop sending and modifing the output values of the two signals and at the same time send a digital signal Boolean in each arch, so when's done it 1024 iterations of the loop I send an event to the digital port. Attached you can see.

  The problem is that I don't know how to synchronize both. Can I use the sample clock just to the analog output? I can use sample for the two outputs clock, or do I need to use the output of the meter? If don't know how to use it here.

  If I do nothing else bad/wrong, I would be grateful for feedback.

  Thanks in advance,
  Pablo

  I don't know how but I find the solution. I'm generating more than a positive value (as I was triggered maybe very fast the oscilloscope has been absent there). If I put the sample clock of digital output to use the sampling/ao/Dev1 clock that it doesn't, but if I put to use the same source as the OD (terminal where my external clock is connected), but the trigger to start the DO to be Dev1/ao/StartTrigger this works. I don't really know why, but it does.

  Thank you for your patience and your help. I put here the final code.

• Problem setting up an encoder input and PWM output tasks on CompactDAQ

  I use a chassis with a modules 9474 cDAQ-9174 and 9411. I do not think it is important, but they are the cRIO-XXXX modules NOR old provided with a test configuration that has been distributed to early adopters. I use DAQmx tasks in an application (C libraries) to read (angular position) quadrature encoder and drive a motor directly with PWM current (pulse output). For various other needs, my tasks Setup is as follows:

  [DAQmx] MajorVersion = 9

  MinorVersion = 2

  [DAQmxChannel venture 9411 wheel entry/AngularPosition]

  CI. AngEncoder.PulsesPerRev = 500

  CI. AngEncoder.InitialAngle = 0

  CI. Encoder.ZIndexVal = 0

  CI. Encoder.ZIndexPhase = a Low high B

  CI. Encoder.ZIndexEnable = 0

  ChanType = input meter

  CI. MeasType = Position: angular encoder

  CI. AngEncoder.Units = ticks

  PhysicalChanName = cDAQ1Mod2/ctr2

  CI. Encoder.DecodingType = X 4

  [DAQmxChannel venture 9474 PWM output/PulseOutput]

  CO. LTD.. Pulse.IdleState = low

  ChanType = output meter

  CO. LTD.. OutputType = Pulse:

  CO. LTD.. Pulse.HighTime = 5.0000000000000004E - 006

  CO. LTD.. Pulse.LowTime = 5.0000000000000002E - 005

  CO. LTD.. Pulse.Time.InitialDelay = 0

  CO. LTD.. Pulse.Time.Units = seconds

  PhysicalChanName = cDAQ1Mod1/ctr3

  [DAQmxTask venture 9411 wheel entry]

  Channels = venture 9411 wheel input/AngularPosition

  SampQuant.SampMode = continuous samples

  SampClk.ActiveEdge = Rising

  SampQuant.SampPerChan = 100000

  SampClk.Rate = 100000

  SampTimingType = sample clock

  SampClk.src=/cDAQ1/100kHzTimebase

  [DAQmxTask venture 9474 PWM output]

  Channels = venture 9474, output PWM/PulseOutput

  SampQuant.SampMode = continuous samples

  SampQuant.SampPerChan = 100000

  SampTimingType = implied

  RegenMode = allow regeneration

  [DAQmxCDAQChassis cDAQ1

  ] ProductType = cDAQ-9174

  DevSerialNum = 0x18B3EC0

  [DAQmxCDAQModule cDAQ1Mod1]

  ProductType = NOR 9474

  DevSerialNum = 0xDEDF40

  CompactDAQ.ChassisDevName = cDAQ1

  CompactDAQ.SlotNum = 1

  [DAQmxCDAQModule cDAQ1Mod2]

  ProductType = NOR 9411

  DevSerialNum = 0xDEDB24

  CompactDAQ.ChassisDevName = cDAQ1

  CompactDAQ.SlotNum = 2

  Each task works fine on its own (i.e. without the other). The problem is that if I start the task of the encoder first and then the task PWM, the latter causes an error:

  Error-89137 occurred to the DAQ Assistant
  Possible reasons:
  Specified route can not be satisfied, because it requires resources that are currently in use by another route.

  Source device: cDAQ1
  Point source:
  80MHzTimebase
  Destination device: cDAQ1
  Destination
  Terminal: Ctr3Source

  Need for resources in use by Source
  Feature: cDAQ1
  Terminal of source: 100kHzTimebase
  Destination
  Feature: cDAQ1
  Destination terminal: Ctr2SampleClock

  The task name: _unnamedTask<61>

  I don't know why this is, but if I start the PWM task first, and then the task of the encoder, it also works. I should also mention that initially I was using counter 0 encoder, which caused a shift in the 100kHzTimebase to Ctr0SampleClock, which, according to the ways of device 9411, is not supported. Yet it worked (in itself). I wonder if this is happening under the hood isn't quite what is shown.

  What is exactly the conflict and what can do to avoid it? The reasons for having to use specific modes and the settings (for example, the 'continuous samples' with 100kHzTimebase clock) are rooted in various performance and requirements of optimization that were created in a previous version of our software, so I prefer not to take a completely different path, if some small changes would lead us to correct the problem.

  I appreciate your help.

  Kamen

  Hi Kamen,

  The time base of 100 kHz is not a direct route to the counter sample clocks, the device actually uses one of the other counters to complete the road (the routing table is a little misleading here because it shows 2 meter that one always doing road - in fact it will be any available counter):

  

  So in your case, when you start the task of the encoder, it uses one of the other available counters to complete the configured road (100 kHz to ctr2 sample clock timebase).  Of course, she chose meter 3.

  Possible workarounds (looks like you have already found one yourself):

  1 start the PWM before the task of the encoder task - if the task PWM starts first the counter is already booked and the task of the encoder would choose another available counter to complete its road.

  2. explicitly reserve the PWM task before you begin the task of the encoder (if you need to start the task of the encoder first).

  3. use cDAQ1/_freqout to generate the clock sample 100 kHz signal and use this instead of routing to the time base of 100 kHz to the counter sample clock.

  Change autour counters should also work, but I'm not 100% sure how the unit selects which counter to use for routing (I don't expect change in the future, but if it's not explicitly spec'ed somewhere so I wouldn't take my chances)-if it were me, I would choose one of the other options above.

  Best regards

• Basic measures and the output impedance of the change with PXI-4461?

  Hello

  I am required to build an audio station with platform PXI OR test.

  It is my first experience with Renault. So I don't really know a lot...

  The PXI-4461 is a replacement of a former HP audio Analyzer. The measure is quite simple:

  1 generate fixed freq signal and measure AC RMS power

  2 measure THD (total distortion harmic) at frequency fixed

  3 measure SNR (signal to noise) at frequency fixed

  4 generate and measure DC signals

  5. change the output impedance of 50 ohms and 600 ohms.

  If I have a good feeling on which tasks 1 to 4 are feasible. I would like to ask if the task 5 (change the output impedance) problem possible?

  If this isn't a work around?

  As for tasks 1 to 4, it is possible with out doing 'a sound vibration' Toolkit?

  How helpful the Toolbox will be for the tasks listed above (humble).

  What should be my starting point learn to manage these measurement with Labview?

  Thanks in advance

  Hi Hazkel,

  Sound and Vibration toolkit will help a lot with steps 1 through 3.  This without the Toolbox would require a very high level of knowledge with LabVIEW and you will probably run again for complications.  In response to the fifth step, I tried to adapt the output impedance and am not able to do so programmtically.  However, you can still do this in hardware by adding a shunt resistor and potentially switch between if necessary impedances.  We have an article that deals with impedance matching and a circuit configuration to set the impedance if you are interested:

  I recommend starting with examples that we have already built in LabVIEW to familiarize yourself with the concepts.  You will find them by clicking on help-> find examples-> search, then search for your application. Please let me know if you have any other questions.

  Thank you
