• Slow refresh rate using a D3100 connect two monitors U2311H

  Hello

  I have a macbook pro 2016 and bought the Dell D3100 triple display USB adapter to use with it. The two monitors are connected to DVI using adapters connected to the displayport and hdmi ports. I installed the latest drivers from displaylink for El Capitan on the computer and plugged the dock on USB 3.0. The two monitors work. However, they all seem to have some considerable delay. Testufo indicates that they are both running at 60 Hz (as well as the display settings), but movement seems choppy and fuzzy, akin to 30 hz, but maybe a little better.

  I read that it would be able to run monitors 1080 at 60 Hz with little trouble. Is there something I am doing wrong?

  Thank you

  We didn't test the D3100 on Apple hardware or software is a big unknown.

  
  The slow refresh rate tells us that they're not really running at 60 Hz.

  The U2311H has the following ports video =.
  DP 1920 x 1080 60 Hz
  DVI 1920 x 1080 60 Hz
  VGA 1920 x 1080 60 Hz

  The D3100's video next ports =.
  Display Port 1.1 = 3840 x 2160 30 Hz, 1920 x 1080 60 Hz
  HDMI 1.4 = 2560 x 1440-50 Hz

  So the U2311H using DP 1. 1 a/DVI should be 60 Hz. The other at 50 Hz. But how the Apple operating system is to see these is unknown. You must post on the Apple Forum of Discussions and see if they can offer an overview or troubleshooting steps.

• MV slow refresh

  now that point of view taking an age to refresh as before, there is a newspaper of MV, I suspect that I have not used "with rowid" clause during the reconstruction of the materliazed view, how do I add with rowid clause which I think will improve the refreshment of MV.

  >
  I forgot to use the following clause, wonder can I change the MV for adherent ROWID clause? What worries me is if I do not include the ROWID clause in this MV by all means, this causes delayed refresh MV?
  >
  Re-read your previous answer.

  Just rebuilt the MV by adding the WITH ROWID clause. The reason that you have built the MV on the predefined table is because it built quickly so just build it again.

• The thick, horizontal lines appear in source and program Viewer footage set to less than 100%...

  Can anyone help?

  This suddenly started across all projects, including those that I worked on for centuries without any problem.  Everything else seems to be exactly the same in other applications than ever before, PP only is affected.  The film is all progressive (I rarely encounter interlaced nowadays), prores HQ 25 fps, usually 1080, but also 720.  Output to the screen, through MXO2 mini is fine and has not changed at all.  I can't think of updates recently, certainly not in the last week, when it started.

  It's really weird and obviously wrong, but I can't begin to find how to solve this problem, after exhausting all my standard corrections (settings in the application hardware, OS, etc. all checked and rechecked.  Made restarts - without result).

  My system is:

  MacPro 5.1 6 hearts 3.33 GHz

  12 GB OF RAM

  GTX285 Mac GPU - CUDA 5.0.45, GPU driver 1.3.4.0 (295.00.05f03)

  OSX 10.7.5

  PP CS 6.0.2

  MXO2 mini - latest drivers etc.

  All thoughts, much appreciated!

  Thank you

  Dominic

  Well, I think I have fixed it but any the wiser for why I got this problem.

  Fixed by upgrading my OS to OSX 10.8.3 (always experience trembling nerve), after my startup etc. disk cloning.  Then I updated to the latest CUDA, reinstalled my Matrox drivers and crossed my fingers!  Fortunately, everything seems fine now.  I can only think that the problem was, perhaps, something to do with CUDA, because the only time where I never had a problem has been using PP and reading less than 100% scale.

• OBIEE - new view just created. Instant results in 'view data' - slow responses

  Hello
  
  I created a view of a table with a long data type, so a function has been used to convert to varchar type. When I execute a select statement with this in Toad or query tool results come back instantly, and when I press 'View data' in obiee they show in 3 seconds. Then I created an answer and put the two columns in the view of the report and he ran so he comes to see the columns. There are 30 000 REB. It takes five minutes to list them. Is it possible to get it to run faster please?
  
  I'm actually just simply wanting to calculate the sum on them, but this takes 5 minutes also. I expected to just list people instantly well.
  
  Any ideas please?
  
  Kind regards
  Hilary.

  Hi hilary,

  Have you used this datbase opinion that has been created in RPD in the physical layer by accessing the properties of the table and use SQL and write your review.

  Apply a guest on one of the attributes of your report, so you can filter the data in it and you will get less data out of it that gets you in no time.

  If the answer scores points for all your discussions. Its label of forum and it would be useful to others.

  See you soon,.

• Ali g 11, view is not refreshed when model

  Hello
  Really miss me something adf faces (jdev 11.1.1.3.0).
  
  I have a web app with jspx, tabpanels and pojo data controls.
  
  Since there is no complex logic to open new pages/tabs, sometimes I have to open new pages/tabs programmatically, and I also sometimes
  to refresh the model behind pages/tabs programmatically.
  
  When I say "programmatically" I mean that the updating of the model is not started by an action of the user on the Web page, but it is started by logic in the model layer
  (say, for example, you receive a JMS message and you want to reload the entire page content).
  
  I can correctly update the model, using debug println I can see that the template is updated, but there is no way that I can update the view.
  
  I tried with the code "addPartialTarget" and so on, but it does not work.
  
  
  I have also bought and read "Oracle JDeveloper 11g Handbook" and "Oracle Fusion Developer Guide", but I can't find anything that can help me.
  
  
  Can someone explain to me: what don't understand me? I don't know there's some notion in ADF Faces I missed: this framework is too
  big not to offer what I need, so I missed something for you.
  
  I hope to have an answer, I hope Shay reads this too.
  
  
  Thank you all.

  Hello

  Active Data Services (Chapter 20 of the book) is what allows you to synchronize the screen with changes made to the model. The problem you face is because the data that you see is what is stored in the link layer iterators. An alternative to the use of the ADS is to use an af:poll component that updates the display component when the model has changed. To do this, your model exposes a method that returns a timestamp which changes each time the data has changed. On the expiry of af: poll, he calls a managed bean method, which - through the ADF link layer - checks the timestamp and compares it to a local saved copy (whenever the timestamp has changed, the client side he wrote for example to the viewScope or pageFlowScope). If the timestamp has changed, the managed bean reruns the method of the iterator for the user interface components and then issues a partial refresh of the components. "Instead of PPR'ing each element in turn, you can try setting the property ChangeEventPolicy of the ppr iterators.

  This should solve the problem. The last example is also explained in the chapter 20, but ADF in British Colombia

  (2) in the inline view more trees, he used ROWID in where clause. I tried to create an index on the ROWID and error

  Note: I checked that I have the index of all the areas in which all the clauses contained in the DML except rowid.
  
  Thanks for help.

  1 apparently Oracle Flashback technology is used when no newspaper materialized view have been implemented

  2 rowid is the external representation of the physical location of a line. The rowid points to a file and a block and a rowid in this block.
  The nodes of an index comprised of a key and the corresponding rowid.
  As a rowid is never stored, you also can't index.

  Your performance issue is the result of outerjoining all tables.
  It is a design error. Outer joins always lead to table scan complete and joins of hash for obvious reasons.

  As your MV is a MV complex is not a candidate for FAST REFRESH ON COMMIT.

  I can see via dba_jobs it as the next refresh (next_date-> 14 January 10, next_sec--> 07:00:00. Everything seemed fine, but labour does not automatically run this morning. I can (and have) run the job manually using:
  Run DBMS_JOB. RUN (109);
  
  Some tips on how I can know what is the problem? I guess I think it's maybe a permissions thing? Thank you.

  What is the result of the above query

• Why is the Event Viewer so slow?

  This question runs through the back of my mind for years, so I give him another chance. Since Windows is using newly designed event viewer (from Windows 7 / Windows Server 2008), it takes an unusual amount of time to display the list of events when you first click on a certain event log. I'm talking about 5 to 20 seconds and I can observe this behavior on every machine we have. I guess that the MMC load all alone before display event log chosen and therefore takes this huge amount of time. It's always annoying if you open Event Viewer, several times a day and I'd love to have this problem.

  I guess that the MMC load all alone before display event log chosen and therefore takes this huge amount of time.

  Yes, it takes a lot of time to read all the newspapers from the hard drive, fill in the table in memory, then filter for the one (s) you selected.  I've heard a lot of work going on in this Windows 10, but as it is rarely used (and Windows 7 is beyond the end of the chronology of support), you get any updates to fix on Windows 7.

• folder view is not refresh after deleting file

  Win7 64

  Folder view is not updated after deleting the file.

  Needs of F5 update or change directory...

  Erraticly appear.

  It's just impossible to give such a system a simple user.

  Apparently a problem experienced in years...

  Just thinking about moving to Linux entire PC fleet.

  Hello

  Step 1:

  You can check if the problem continues in a new user account. To create a new user account:

  Step 2:

  If the new user account works fine then the old account has been corrupted, you can follow the link given below to fix the corrupted user profile.

  You do not have show us the request, the view definition or the predicate for the plans section; but speculation obvious that you have included the rownum inside the view definition - which makes a view no-that can be merged that must be instantiated before the predicate of the query can be applied.

• Lighroom 5.4 develop view does not refresh when you change cursors

  Just updated to Lightroom 5.4 (using Adobe CC) on Win8. After "saw to develop" on any photo and change the exposure or any other cursor does not update the main view of the photo. He however update the thumbnail in the strip of film and the second monitor window correctly. I have tried everything I can think of:

  (1) demotion to 5.3 LR (which used to work)

  (2) force the regeneration overview standard and 1:1

  (3) uninstall the re - install Lightroom (5.3 and 5.4)

  (4) maximize the catalogue

  (5) remove the folder AppData Adobe

  (6) creating a new catalog with zero pictures, import a single photo and try to change exposure/contrast on this

  None of these results in the view to develop the image change when I change the cursors.

  Guys do you have experience with this?

  Hey entombed123,

  It seems that I found what the problem is - it's to follow the color profile. Attempt to set the default and check again. It worked for me and a few people who have had this problem before.

  Good luck.

• View LOV slow object

  I have a page with a selectonechoice field that has an LOV element based in a view accessor.
  
  This view accessor based vo that has 900 records in the database. This is a table of multilangueage of the countries (238 in four languages-> about 900 records).
  
  The problem is that when the page is displayed the first time it takes about 30 seconds to appear. When I ask againg for the page, then it is much faster (I guess because the original Version is already loaded).
  
  I have being debugged it and it seems that this is the time that ADF has to load all the records of 900.
  
  Run the aPPModule and the VO of country, when I ask for the last record it also takes about 30 seconds.
  
  What can I do to speed it up? I don't know why ADF takes so long to load 900 records? In fact the LOV display only 238 records because there is an active viewcriteria filtering by language, but it takes the same 30 seconds.
  
  This original Version is only for the purpose of the LOV and so it's a read only VO.
  
  Any idea?

  have you tried not tuning your LOV VO?
  See these -.

• materialized view full refresh much slower that recreate

  Hello!
  
  We use the view materialized for our DWH, which freshen every day to demand and full. I noticed that after some time refreshing take very long materialized view (1 h), recreating the view materialized and refreshing it at the same time just takes a few minutes. The result is exactly the same thing.
  Can someone explain to me why this is the case? And is there a better way to recreate materialized view that copying and running the entire SQL statement?
  
  Thanks for your help!

  Since 10g or 10 g 2, the default behavior for a refreshment FULL of a MV is DELETE and INSERT.
  (In 9i, it was TRUNCATE and INSERT - which was, obviously, faster).
  The advantage with the DELETE and INSERT, is that the data are still visible in the MV while it is updating.

  See Oracle's Support article:
  Refresh complete reading consistency behavior during refresh and refresh complete Performance influenced by the setting of refresh ATOMIC_REFRESH [ID 553464.1]

• Smart view in the slow with office 2010 but fast zoom with office 2007

  Smart zoom view in slow for a user with office 2010, but the same zoom in fact with office 2007 comes back almost instantly.

  What version of Smart View / APS?  How many lines is returned by the zoom?

  Do you know that absolutely all of the options are identical to get it back ('use Excel put shaped' makes a big difference to big zooms)?
