• What is the difference between levels 1 to 4 of the performance monitoring? What is the default level?

  What is the difference between levels 1 to 4 of the performance monitoring? What is the default level?

  Collection and levels of collection intervals are two things that are used to monitor and collect statistics of performance for entities.

  Research in detail what intervals of Collection and collection levels mean:

  Collection intervals determine the duration for which the statistics are gathered. VirtualCenter currently has four intervals of collection: day, week, month and year.

  Every interval between two collections has a default collection level that determines how the counters are used when collecting statistics. Default collection-level is set to 1 (because the minimum number of counters). This level is configurable and can be set from 1 to 4.

  For more details on the intervals of the collection and the collection level (with respect to the measurements taken at each level), please see the "Collecting statistics" section, page 281 base System Administration Guide.

  http://www.VMware.com/PDF/vi3_35/esx_3/R35/vi3_35_25_admin_guide.PDF

  Hope that the information above will clarify your doubts regarding the level of default collection and what they mean.

• What is the cache shared between processes?

  Hello
  
  When I set the cachesize to 200 MB in each process, this means that each process will 200 MB? Or is there a chance that it is shared? As I use PHP scripts in a multiprocessu environment to access the database I want to know the impact on memory consumption.
  
  Thank you

  Hello

  I don't understand. If they do not share the environment, they not have to access the same data? (so what's the question?)

  Fix. You can ignore these remarks; I just wanted to highlight some effects of the process does not share is not the same environment (for example when the process may incorrectly specify different environment directories).

  If these numbers seem very good, Don't they?

  From our point of view, it would be ok if latency increases when you increase the load with multiple virtual machines. But as already out doubled over our cluster becomes broken after increasing the number of virtual machines at some point.

  We are currently testing with a subset of four nodes VSAN with the above config. In this group, we were able to turn on 187 load generation machines before that three of the four hosts entered the State "is not responding.

  We wonder if anyone has also made large performance tests. If so, we would be very interested in comments you make. Maybe this helps us to find the fault of our construction.

  Kind regards

  Daniel

  With the help of VMware we discover that the problems we face are caused by virtual machines gen load... each vm is generating 2048 ios in circulation... so with 187 VM on the cluster, we unreal ios in circulation (382976... when I remember the graphic observation of our cluster it would reduce up to 13000 per host) which we will never see in real world scenarios. With this high traffic vsan 6.1 ios has problems and vmware is working on a solution... maybe with 6.2 and qos that is resolved?

  A few other changes:

  -a newer driver for our network cards intel x 710

  -new driver and firmware (beta version of dell) for our h730 perc controller

  and some advanced settings:

  esxcfg-advcfg - 100000/LSOM/diskIoTimeout s

  esxcfg-advcfg - s 4/LSOM/diskIoRetryFactor

  esxcfg-advcfg - s LSOM/2047/heapSize (with these parameters, we were able to create 3 starts - with 7 metal discs and 1 flash device - for each host)

• Number of elements must be set to the logical level

  In the channel Business model, mapping, dimension > logic > > number of items at this logical level
  
  I came across two different versions of how to treat this
  
  First version - the OBE and the server admin guide, it says "the number does.
  no need to be exact, but the numbers of one logic level to the other, rates should be accurate."
  
  Second Version - a question asked about what defines the number level both as best practices
  
  To set the number of items at each level of a dimension, what number would you use?
  
  A. the number of columns in a logical table
  B. the number of levels in a dimension
  C. the number of dimensions in a business model
  D. the number of tables in a physical model
  E. the number of separate lines in the physical column

  The relationship between the levels, which is important according to me. BI Server will use this information to determine which source of aggregation to use. You must use the number of separate lines as the value.

  You can also right-click on the hieracny and "Levels of estimate" allows you to automatically fill in the numbers for you.

• Where is the information on the "Patch level" of a particular version

  Hi all
  
  Where I can see what is the last "Patch level" a particular version of Tux. For example, what is the last level of Tuxedo 9.1 patch, where I can find on?. This information is public? We need an oracle contacts?
  
  Thanks in advance

  Hello

  If you try to determine what is the last level of patch available for a given version, you will need to contact Oracle customer support. I don't think that we have a site accessible to the public that provides this information.

• What is the log message of consistency for the expiration of cache framework?

  Hello

  I have an obligation to monitor consistency logs when framework automatically empty the cache based on the value of timeout.

  Can someone tell me what the logging level you should see that message and what message should expect?

  Thank you

  Akanksha

  I could be wrong, but I think consistency of these data logs fine grain.  Easy, just test well - just turn the level up to 9 newspaper and expel some entries!

  Furthermore, I always ran again my production servers at the level of the journal 9.  It's pretty standard to do.

• What is the big secret...?

  I read the book of Keith Peters called "ActionScript Animation 3.0"
  
  The reason why I bought this book was because of people saying it's great for those who want the animations in flash code rather than using a calendar and frameworks for interpolation, etc..
  
  But the book is not helpful at all. Not for me.
  I order the part on the creation of an object and do move, but the parties to do that the object looks like it's lively just seem to make sense for me.
  
  A common mistake is (according to the book) use the code:
  
  for (i = 0; i < 500; i ++) {}
  ball.x = i;
  }
  
  Although the fact ball end by point x desired he wants be animated her you might want to because the "i ++" happens before the ball.x is defined.
  I understand the logic of this part.
  
  But what the book does not cover the right code to get the ball to animation to x-point (A) to x-point (B).
  
  I flipped pages in the book several times and can't seem to find the right side containing the code necessary to place the ball on the stage, while the x-point is calculated so that the ball is lively as I want.
  
  The book says that I need to create a loop that runs over and repeatedly until the new x-point for the ball is while the ball is put on the stage in the loop with the new coordinates calculated during the loop.
  It's pure logic, and I understand!
  
  But... HOW TO CREATE THIS LOOP WITH THE NECESSARY CODES?
  
  Here's what I want to do:
  I have a nail of the thumb-menu that I want to move from one side to the other when a mouse event that happens.
  
  Event occurs by clicking both mouse buttons ('next' and 'prev').
  
  I get the menu thumbnail to move from one side to the other, but it does not animate. He jumps again x-point rather than slide smoothly on the scene.
  
  So, what's the big secret?
  What is the logic seemed before is not logical...
  
  I need all the help I can get... It's for a Web site and I'm already behind schedule...
  
  Perhaps becomes just a few simple codes set up the right way, but I work with the most complex Flash and move it forward.
  
  
  

  I recommend the 'Tweener' IN the library (see the tutorial on Tweener to http://gotoandlearn.com/player.php?id=45 ). You can also use a frame entry or the Timer class event. You can find full info using Flash (press F1 in Flash).

  Enter Frame event:

  stage.addEventListener (Event.ENTER_FRAME, updateBallPos);

  function updateBallPos(ev:Event):void {}
  If (ball.x< 500)="">
  ball.x ++;
  }
  }

  ActionScript 3.0 Animation: Making things move! is a fantastic book, but requires a bit more knowledge of ActionScript.

• Clear the cache of 2nd level tabs

  Hello
  I have a question related to the clearing the cache in an application level tab structure two. If you look at the examples of Denes Kubicek, you'll see that it uses a structure of tab level two. The horizontal bar under the header is level 1 and the left 'bar menu' is level 2.
  I also tried to implement, because I think it's a real nice way to offer a good navigation structure. But I've not found a good way to clear the cache of a page that opens when someone clicks on a tab-level 2. Someone at - it an idea? Perhaps Dene itself can help out me?
  Thank you!
  Jacob

  I think you speak standard tabs as a parent as the first level and second level. I think always of them the other way around. Well, what you need to do is create a process that is triggered (by default, for each page view) depends on demand, which is the name of the tab (T_ORDERS, for example). The point process of shooting must be on submit - before the calculations and Validations. In this process, you can determine the page being presented with the help of the standard tab: APP_PAGE_ID and the name of the page layout tab, again, in using: ASK. Then, the process can call apex_util.clear_page_cache to do the cache clearing you need.

• Clear the Cache and Cookies... downside? What problems this may create?

  I'm having problems of speed, scroll wheel, etc... and didn't "clean" my MacBook Pro 15 "Late 2008 with upgrade of RAM because I do not know how to clean it up." So, I was informed that the cache and cookies from 8 years of use of the compensation would be a good start. Before you do it... What problems it will create? WilI I need to know ALL the passwords and ID to all my sites, I need to prepare and or know that I need to deal with when I do this? Are there other things 'cleansing' can I do to make my MacBook Pro works best? Thank you and God bless you!

  Start with these simple steps (after that you made that you have a backup of all your data!):

  1. Start or restart your Mac.
  2. As soon as you hear the startup tone, hold down the SHIFT key.
  3. Release the SHIFT key when you see the logo Apple appears on the screen.

  This will put you in Mode without failure, which will be even slower than you used to. Don't worry: after starting over, you can immediately restart in normal mode. In this way, a lot is 'cleaned' automatically.

  If it doesn't improve speed, thanks for posting a report of Etrecheck: http://etrecheck.com
