• What is the fastest method producer consumer. Queue, RT-FIFO, event

  Hi all

  Another question completed for the pro:

  I recently inherited the labview code that uses RT-FIFO for the transfer mechanism in the architecture of the producer consumer.

  The code was first written in 3-4 years and is currently in LV8.6. It is possible that the reasons for the architectural decision no longer exists.

  I am qualified using a producer consumer queued architecture,

  I understand the RT-FIFO Architecture.

  I started using an architecture based on events from the user.

  (I have attached samples of each)

  I also see the existence of a priority queue

  Each method has its own capabilities and gaps, that hand, nobody knows the relative performance of each method.

  (Assuming that the only process)

  I would expect RT-FIFO to be faster, there seems to be a version of low characteristic of a standard queue.

  What is the perfornace hit to use a coding user-friendly queue more

  RT-FIFO description talks about commications between the time-critical and lower priority threads.

  Until today, I thought that the queues had the same capacity.

  

  I've included an event method that I commonly use for review by peers and help from other users...

  It allows to:

  1. several producers with different types of data

  2. process 37 production order.

  3 allows asynchronous verification of functional notifiers such as stop, start and abort.

  4. in a system not real-time, it can include interactions of façade.

  What I do not understand on this subject, that's what are overhead or thread priority changes that may occur using this architecture (it solves a lot of problems for me).

  Thanks in advance,

  Hi Timmar,

  Here's a KB article on some frequently asked questions about the RT FIFO: http://digital.ni.com/public.nsf/allkb/7AE7075AF1B2C58486256AED006A029F?OpenDocument

  The more relevant question is #4, I posted below.

  What is the difference between RT FIFO and queues? 
  Functionally, RT FIFO and LabVIEW queues are two pads of first in, first out. However, here are the main differences between them:

  • RT FIFOs run deterministically in LabVIEW and evanescent code queues are not. This comes from the fact that queues use block calls during read/write to the resource shared, while RT FIFOs use non-blocking calls.
  • RT FIFO are fixed size while queues develop when items are added to them.
  • RT FIFOs will execute the code, even if there are input errors. They can (and will) produce new errors and spread the existing errors.
  • Queues work with any type of data, while the data types that can be used with RT FIFOs are limited. Generally any type of data involving allocations of extra memory can be used with RT FIFOs to preserve determinism.

• What is the free space in Vista variant of +/-50 GB?

  Last night when I went to bed my system reported that I had 60 GB free. This afternoon, he pointed out that I have more than 111 GB of free. I have not emptied the trash, run Disk Cleanup, installed updates (it is set to "notify me but do not install" after this update in the fall of 2009, which made me unable to get on the internet) or anything that could justify such a wide gap.
  Accustomed to the amount of free space fluctuating by the swap file systems, I'm my system has only 6 GB RAM and what I have observed, I rarely fully used that. I expect a variance of + / 12 GB or more, not 50 GB.

  Is it normal for Vista 64-bit home premium with AVG free or is something current weird that I should try to trace? I only noticed because I knew I had to free 20 GB (probably more like 30-40) for a 580 GB partition on a drive of 500 GB of images and was preparing to move some installers downloaded from CDs and DVDs.

  To study disk space, use download and install Treesize (freeware).

  When you open Treesize scan select in the Menu and you will see a list of drives. Click on C and it will generate a list of files. Display names and 6 larger files sizes and the total at the top of the list.

  To reconcile Treesize figures with the size of a partition (or drive), you must make allowances according to this formula:
  Partition C + folder System Volume Information + Free space + file compression gain = ability to drive or partition

  To determine the size of the System Volume Information folder, select Start, Control Panel, system, System Protection, click Configure under Protection settings. What is the figure of the current use?

• What is the difference in coverage and coverage before holes?

  Hi all

  Anyone know what is the difference in coverage and coverage before holes?

  I can find the doc of Cisco is:

  «cover holes are displayed as alarms, coverage before holes are displayed as events»

  "The gaps or the 'holes' in coverage of radio access point are the main cause of poor audio. Detected on the client before hole events coverage provides continuous monitoring to ensure that the customer is informed about the existence of these cover holes. »

  It seems to cover before the hole is detected customer, cover hole is detected AP? However, I'm not sure.

  Another question is what trap includes alarm coverage before hole in the dictionary of alarm and event of WCS 7.0? I can only find several cover traps:

  LRADIF_COVERAGE_PROFILE_FAILED

  LRADIF_COVERAGE_PROFILE_PASSED

  However, two of them have no say if for hole cover or the front cover. Don't know what trap will be sent by the WCS to a notification receiver configured to indicate an event coverage before hole, for example:

  Minor - X - 13: 27:52 16/09/10 cisco-WCS WCS SNMP <$2>0x07 da 09 10 0d 1 b 2 c b 05 2-0 at 00: 10.1.1.12: coverage before hole reported by 00:1f:3 c: cd:c8:2 detected by 10.1.1.12: coverage before hole reported by ' 00:1f:3 c: cd:c8:2 has ' found on the controller

  Your valuable contribution is very much appreciated!

  Hello!

  A front cover is when a client remains for 5 seconds in a coverage hole. In other words, when a customer is heard for a while to wrong signal and is not roaming, it must mean that this area is a coverage hole. This event is informational

  A coverage hole event is when several clients are pasted into the same hole in coverage. Then the AP will increase its power if possible.

  WLC waits for several clients before trigger power avoids crazy behaviors of increasine/reduction/increase/decrease.

  The settings for cover hole events can be configured on the part of MRR of WLC (number of customers, etc...)

  Nothing is configurable for cover before hole because it's just '1 customer only reached the hole in coverage thresholds '.

  Hope that clarifies.

• What is the difference between OCÉ and (OCP and OCS)

  What is the difference between ECAS and (OCP or OCS).

  For example, I heard that OCS helps with the language

  and the marketing of a product.

  Could this be true as ECAS focuses on how to do things.

  and not so much things to a much higher level.

  For example, how do you set up, how you use it, how do you start, etc.

  Thank you Roger

  Roger,

  OCÉ Doghouse more. These certifications can be more CERT of intermediate or high level certificates. These were specifically developed for the gaps in the certification that did not match our OCA, OCP, hierarchy of the CMO.

  Generally, the CERT of the OCS tend to focus more on implementation. These certificates have been developed for the Oracle PartnerNetwork for areas of certification which specifically serve Oracle partners and qualify them for levels of specialization. These certifications are available for all candidates, but are directed towards members of OPN.

  I hope this helps.

  Kind regards

  Digital badges are a concept that allows employers to be certain that no one 'X' that says that they hold (for example) Oracle Database Administrator Certified Professional 12 c credential - really holds them there. No 'X' can now fill their LinkedIn profile "Certifications" section with any number of impressive certifications - if they have really them.  Digital badges, however, are verified by a collaboration between Acclaim (a service digital badging from Pearson view) and LinkedIn.  Someone cannot display a digital badge of a credential given without having actually been verified to hold.

  http://certmag.com/Digital-badges-may-help-bridge-certification-credibility-gaps/

  In any case - to my knowledge - there is nothing you need to do.  Application of digital badges Oracle is in the baby-steps stage and I know they will continue to roll out over the coming months.  They should send email to certification holders to allow them to perform the badging process.  I think they started with the CMO credentials as a test and increase outside with others.

• What is the range of values of type of data accepted by prepareBulk file?

  In the Oracle documentation under "bulk 7.12 load graphics Using RDF Semantic support for Apache Jena", I see the code example for perpareBulk. The third parameter is documented as "type of data file: can be RDF/XML, N-TRIPLE, etc.". I found a thread code example that uses "TTL." as a value as well. It seems that "TTL" is accepted but not documented. What is the range of accepted values for the type parameter of data to prepareBulk file?

  Hello

  You can use the triple data serialization format following as string values:

  "RDF/XML", "N-TRIPLE", "TURTLE" (or "TTL") and "N3".  "RDF/XML-ABBREV" is a synonym for "RDF/XML".

  For the quads, you can use either "N-QUADS" or "TRIG".

• How to replace the real gaps between the waveform with Silence?

  Is there any Automation I can use for this? I tried the diagnosis, but it was not what I was looking for. Toppings of diagnoses, or real breaks removes or gaps, I like to keep the correct gaps, I want to just reduce to silence all at once, with a single command. Help, please!

  There is no way to do this completely automatically. However, there are two ways that might be time saving. Normally, it is easier to do it manually but which may seem tedious. If you assign a shortcut to the command of Silence key, then this is fast enough to get through the file manually mark each region one both and use your shortcut key to shut parts of the selection.

  Another way is to use the Noise Gate or Expander mode Dynamics Processor to automatically reduce the level of any audio below a certain level. Try the Noise Gate > 20dB preset but move the 20dB point to something that is below the level of any speech search.

  Although generally it is clear that sounds a little artificial if you cut all the gaps completely since the human ear is used to hear some background noise during gaps in the speech. Usually, the best way is to find a fairly quiet background piece and which allows to replace unwanted sounds in the interstices.

• What are the relationships between the logging and IKM?

  What is the best method to use in the following scenario:
  I have about 20 tables with the large amount of data sources.
  I need to create interfaces that join the source tables in target tables.
  The tables are inserted every few seconds with about hundreds of thousands lines.
  There may be a gap of a few seconds between the insertion of different tables that could be attached.
  The source and target tables are on the same Oracle instance and schema.
  I want to understand the role of: 'Logging CDC' and "IKM - incremental" and
  How can I use it in my script?
  In general, what are the relationships between "Logging" and 'IKM '?
  Use both? Or maybe it's better deelte and insert the target tables?
  
  I want to understand what is the role of "Logging CDC"?
  Can 'IKM - incremental' work without "logging"?
  Must 'Logging' have PK on the tables?
  What should I do if I can't say PK (there may be several identical lines)?
  
  Yael thanks in advance

  Hello
  Thanks for your quick response!

  No probs - its still fresh in memory I did a major project on this topic last year (400 tables, millions of lines per day (inserts, updates, deletes), sup-5 minute latency). The problem is it isn't that well written on the web, that you have read the blog of the example I linked to in my first answer? See also here: http://odiexperts.com/changed-data-capture-cdc/

  Always on logging:
  My source table is inserted all the time.
  The interface to join the source table in the target table.

  In ODI, the correct term would be your source table "fits" in the table target, unless you mean literally that want to join the the source with the taget table table? My question if you want to do with the result of the join?

  What exactly the "journaling" CDC updates?
  It updates the model of ODI? interfaces? The source of data in the model of ODI? The target table?

  Logging CDC configures and deploys the data capture mechanism (Triggers or log based capture, IE Logminer/streams/Goldengate) - it is not updated the model as such, she pointed out the metadata of the model of ODI repositoty as a CDC data store, allowing you, the developer say ODI to use log data if you wish (reported in the interface) There is no change in the target table, you get an indicator of metadata (IND_UPD) against a line during the integration (in C$ and I have tables$) that tells you if its insertion (I) and update (U) or deletion (D). It had ' lines allow you to synchronize the deletions, but yoy say its inserts only then you probably used use this option. "
  So the only changes are the source table to your interface, another diary data (if you use logging) or the table of the actual source (if not using the logging).

  This is the main thing that I don't understand!

  I hope I made a little clearer.

  Try the following as a quick test:

  Reverse a source table an engineer and the target (at least) table.
  Import the update incremental LKM and IKM.
  Import of the JKM you want to use.

  Create an interface between the source and the target without any deployed JKM.
  Configure the options of JKM on the model, the "Start log" to start the process of capture - this is quite a complex stage and a lot of things to understand what is happening in the source database, better to check code ODI sends to the database and to review the documentation of Oracle database for a description of what his weight (instantiate Tables (, sets of creating change, creation of subscribers etc. establishment of newspaper groups, creating views Journalising etc.) -you will need to consult your Source DBA database initially as ODI wants to make many changes to the source DB (in mode Archivelog process max, parallelism, size, Java etc.)

  Now, edit your interface and mark the table source for use "Journalized data bank.
  Restart your interface

• What is the version of dreamweaver that creates the most web friendly search engine?

  What is the version of dreamweaver that creates search engine friendly web mostly?

  All versions of Dreamweaver are able to produce good web pages, providing the person who uses, she knows how.   It is not the tool.  It is the skill of the person using it.

  Search engine optimization comes down to the base of 3 things:

  1. You need to have lots of keyword rich, relevant and unique content on your pages.
  2. You have to organize this content in good semantic markup (h1, h2, h3... tags p and li).
  3. You must get other web sites respected post links to your web site.

• Export of Muse on the phone Gap

  Did anyone used a Muse to produce content that will be used on the phone Gap? and what are the benefits / disadvantgaes or pitfalls in the use of this process? We try to produce a few apps and would like to muse allows you to create interactions since it is a solution of Visual Basic development, not eating at all just the community was looking for an honest overview of the prospect to do something like that. Thank you.

  Although there is no direct integration between Muse and Phonegap, there doesn't seem to be any reason why the DW Muse to PhoneGap road would not work because the generated applications are basically that run in a virtual browser within the confines of a native mobile application.

  Haven't tried something like that until now and I think the results would vary depending on the complexity of the project created in Muse. Would like to know how some projects turned out of this workflow.

• What is the best way to buy an iPhone Unlocked 7?

  Hi all

  I am currently using T-Mobile and want to get the new iPhone 7. Since there is no option for a sim-free iPhone, what is the best way to buy the new iPhone? Should I get the T-Mobile one full fare? I know that he will be released version but it will come with a T-Mobile sim so what will do with the sim card? Put it away or give it to T-Mobile? Or should I wait for the version without card sim to appear, which I don't think that will come out until November, and I don't want to wait that long.

  Thank you in advance.

  If you do not want to wait to pay full price for the model from T-Mobile.  You can do whatever you want with the SIM card.
