  This is a follow-up question 11g: additional statistics - effects of bad implementation

  In a system, who should use additional statistics, global statistical imagined fault someone intentionally.

  These aggregate statistics seems to stop to move to additional statistics.

  As a special field table user_tab_col_statistics has to mean here.

• Audio effects delayed the implementation

  I have a documentary type sequence, I'm about to finalize. I've implemented a number of audio effects to remove static (e.g., DeNoiser) that sound great on the Board of Directors/pre-production edition. I have audio clips 20, and each audio clip of clear sound effects.

  When I exported the sequence, however, something goes wrong every time. I tried three times (tried exporting as wmv and avi) and the same guard question arising therefrom. For about the first three seconds of each audio clip in the exported videos, audio effects sound as if they are not implemented. After three seconds, it reformats almost itself, apply audio effects, I added initially. I returned and erased each and every animation audio effect, thinking that maybe the problem, and the issue is not resolved.

  This is a flaw known when using noise.

• implement the new iMac

  I currently use an iMac 2009 and 2011 MacAir. I just got a new 2016 21 "iMac and the desire to be very effective in the implementation.

  I currently have a personal user profile and a grad student user profile.

  What would be the ideal way to set it up again?

  (a) continue with the profiles of separate user or use views of segregated funds (and I do not remember how to do this).

  (b) OS partition from the document/data files

  (c) any other useful ideas.

  Thanks for your help.

  How to set it up is to you and do not be in a bad mood, but I think you're overthinking it. Read it please move your content to a new Mac - Apple Support and which should help you a lot!

• How to implement user (specific application) in pl/sql roles

  Hello
  I have an application that stores information for project management. This information is accessible by users who may have different roles with different privileges (for example, project_manager role with privileges to view/update schedule/cost/skills data, developer of role with privileges to view data to schedule etc.).
  
  Based on the role assigned to a user, the pl/sql code should hide information or prevent updates when requestd by the user.
  
  One way to implement it is using very rough logic (a role table and if else or switch case) while selecting / update of the data.
  This logic works perfectly with a handful of roles/privileges and very less information (tables/columns); but gets messy with increase of roles and information. In addition, it is not easy to maintain.
  
  All the world is facing a similar problem before?
  Is there an effective method to implement this kind of security policy in pl/sql?
  
  Thank you

• What is advised to collect statistics for the huge tables?

  We have a staging database, some tables are huge, hundreds GB in size.  Auto stats tasks are performed, but sometimes it will miss deadlines.

  We would like to know the best practices or tips.

  Thank you.

  Improvement of the efficiency of the collection of statistics can be achieved with:

  1. Parallelism using
  2. Additional statistics

  Parallelism using

  Parallelism can be used in many ways for the collection of statistics

  1. Parallelism object intra
  2. Internal parallelism of the object
  3. Inner and Intra object jointly parallelism

  Parallelism object intra

  The DBMS_STATS package contains the DEGREE parameter. This setting controls the intra parallelism, it controls the number of parallel processes to gather statistics. By default, this parameter has the value is equal to 1. You can increase it by using the DBMS_STATS.SET_PARAM procedure. If you do not set this number, you can allow oracle to determine the optimal number of parallel processes that will be used to collect the statistics. It can be achieved if you set the DEGREE with the DBMS_STATS. Value AUTO_DEGREE.

  Internal parallelism of the object

  If you have the 11.2.0.2 version of Oracle database you can set SIMULTANEOUS preferences that are responsible for the collection of statistics, preferably. When there is TRUE value at the same TIME, Oracle uses the Scheduler and Advanced Queuing to simultaneously manage several jobs statistics. The number of parallel jobs is controlled by the JOB_QUEUE_PROCESSES parameter. This parameter must be equal to two times a number of your processor cores (if you have two CPU with 8 cores of each, then the JOB_QUEUE_PROCESSES parameter must be equal to 2 (CPU) x 8 (cores) x 2 = 32). You must set this parameter at the level of the system (ALTER SYSTEM SET...).

  Additional statistics

  This best option corresponds to a partitioned table. If the INCREMENTAL for a partitioned table parameter is set to TRUE and the DBMS_STATS. GATHER_TABLE_STATS GRANULARITY setting is set to GLOBAL and the parameter of DBMS_STATS ESTIMATE_PERCENT. GATHER_TABLE_STATS is set to AUTO_SAMPLE_SIZE, Oracle will scan only the partitions that have changes.

• Can I use After effects with a processor i5 with no problems?

  I am looking for a new computer for editing in After Effects:

  * Do I need a processor i7 or i5 processor yourself run 3D effects and more without any problem?

  * Is enough 8 GB RAM or could go for 16 GB of RAM?

  * Can I run 3D effects and more without problem with GeForce GTX 760 2 GB?

  I have the version of AE called 'After Effects CC 2015' and I can go the feuture uppgrade.

  It is also possible I buy Photoshop...

  Thanks for the replies!

  Bad idea. After Effects is not software editing. You want to Premiere Pro for editing of a film. That's much, much, much better at home because that's what it's designed to do. When it comes to Visual effects, compositing and motion graphics, so you must use After Effects to these tasks.

  Lukwin8 wrote:

  An i5 will work to launch After Effects. The clock speed of the processor will make a big difference in the AE speed makes things.

  Lukwin8 wrote:

  Get 16 GB or more.

  Lukwin8 wrote:

  What are the 3d effects you plan to use? There could be several things that you hear here.

  If you're talking about ray-traced rendering introduced in CS6 engine, I would advise against using it. She is considered obsolete by the After Effects team and I don't know any people who used it professionally.

  If you're talking about the substitute continually improve the ray-traced rendering engine (the inclusion of Cinema 4 d with your subscription to After Effects), the GPU is not relevant. C4D renders on the CPU.

  If you talk about AE own 3d space (which is technically 2.5 d), the GPU is not relevant AE makes it only on the processor.

  If you talk about third-party plugins as item 3d, 3d Zaxwerks Invigorator, Shapeshifter of the courage, etc., you will need to check on their needs.

  If you have after effects CC 2015, then you have a subscription with Adobe which includes AE CS6, CC, CC 2014, 2015 CC and next version of After Effects coming out for as long as you are subscribed.

  How to find and install previous Version of Adobe Apps in 2015 CC

  Lukwin8 wrote:

  If you only subscribe single-app for After Effects, just get the regular subscription to creative cloud. It's cheaper than to make two single-app subscriptions and it includes After Effects, Photoshop, Premiere Pro, Audition, SpeedGrade, Illustrator, Muse, Animate, Dreamweaver and many other professional programs like that.

  If you want to do video editing, you'll want to have Premiere Pro. After effects is ideal for animations, compositing and effects Visual, but it's TERRIBLE editing. Premiere Pro, use for this!

  Hope that helps.

• Replace with After Effects composition

  I am trying to move a clip in Premiere Pro to after sets by using Dynamic Link 'Replace with After Effects composition', when I do so it begins to After Effects and creates a new composition but does not move no matter what media Premiere Pro to After Effects at all. There is just a blank publication.

  Teodor salvation,

  Most of the time that this happens when versions of Premiere Pro and After Effects corresponding bad (works of dynamic link between the same two versions of applications). Make sure that Premiere Pro and After Effects have the same versions, for example, first Pro CC 2014.2 (8.2) and after effects CC 2014.2 (13.2)

  What versions of Premiere Pro and After Effects are installed on your computer? You can check this information under 'On first Pro', and ' After Effects'

  When I click to open the waveform of an audio layer I get this error message:

  «After effects error: not implemented function.» (10::48) "and to make them disappear.

  Remove the MP3.  It is not any kind of audio compressed which works well in AE.  Change the MS to wav or aiff.

• Import clips with first effects in AE

  Hi, I had a search on google and also look through the forums, but found nothing on the subject to:

  I'm trying to import an After Effects project. The project itself is composed of many jpg all places one after the other, and with the transition effect "dissolve" applied (stop-motion for all intensive purposes). However, when I try and import the project into After Effects, the transient effects do not transfer in all leaving me with just the images in the order (which have much less convincing air without dissolving it applied).

  In addition, After Effects doesn't seem to get a preview of the video correctly every time that I start to use the above-mentioned project (the little green bar which marks something like the rendering is quite nervous. Not sure if it's just a problem that occurs naturally when working with projects on AE, but it's pretty boring.

  

  Someone has an idea how to fix any of these issues or are they just inherent problems when working with projects on AE?

  I suggest you to read about the effects and transitions are actually supported when importing projects in AE on aid and whether or not using DynamicLink would help in your case. With regard to the bars of preview RAM - look normal to me. Still images are only cached once to save RAM, if they do not move or have other animations and applied effects. The bar won't green at the actual opening, during work or after the preview.

• Types of implementation of models?

  Experts,
  I was debugging a problem prod for 3 days.
  Somehow I analyzed the problem-
  I have a requirement as below-.
  I have a model rtf, the XML 30000KB size and 46 columns in the report. Output type is Excel.
  Model RTF I have is quite simple (developed by automaticlaly loading all the fields of the data source)
  I can't get an overview of the report using the rtf for these big data and the columns.
  I tried posting the report reducing xml file very less size of about 2000 KB. I could get a glimpse to now.
  
  How to manage reports for large data.
  
  I would try an alternative for this.
  I have the model ready, rtf and xml.
  any additional info on how to implement this?
  
  I think that I am not able to view the data of such xml file large, due to the rtf model (I don't know - if someone could confirm the same thing)
  So I don't want to switch to other types of model. What type of templte will be perfect for my needs. How do I implement this.
  
  Please help me.

  Not sure if you have already done this. Try increasing the value of Java heap space.

  This is possible in Word-> option BEEP-> tools-> Options-> Preview-> Java Option.

  Set this value on - Xmx1024M and check if you are able to get a preview of the data.

• Problems of Apple TV 2015 - work, Watched & Autoplay

  Hello.

  Recently I bought the new Apple TV, and in the first 2 hours of use, I have seen a ton of bugs and bad implementations.

  1. why videos AutoPlay? Who got this idea? So when I fall asleep my Apple TV through the season and the mark as watched scrubs? How will I know the other day where I left off? (Who never had this idea isn't so bright)

  2. There are 2 LARGE VISIBLE BUGS which should not only have occurred in Apple. First of all, being the blue dot for unattended or video episodes. After watch you the episode the blue dot will not far (EVEN SAYING THAT THE VIDEO is not WATCHED). You have to go back a step and that still in the living room to see it deleted.

  3. THE most GRAND SECOND BUG VISIBLE and that I want to pull my hair out and return to the Apple TV all together is the! DISAPPEARANCE OF THE WORK FOR THE NEW SHOWS ADDED!  (IN THE MAIN HOME SCREEN)

  I use an application called iFlicks that intercepts all the metadata and the work of movies and tv shows. It works like charm on my Apple TV 3. I tested it immediately when I noticed this bug and ATV 3 works great.

  THE PROBLEM, IT IS THAT THE NEW APPLE TV DOES NOT WORK SOMETIMES, WHEN IT DIDN'T THERE HAS MORE THAN 1 SEASON.

  BUT RECENTLY, I have SEEN that HE does is not DISPLAY 1280x1280px JPG

  THE ONLY THING I CAN DO RIGHT IS NOW TOO draw ON the WORK of ITUNES, resize it to 900x900px, EXPORT AS. PNG AND CHANGE IT IN ITUNES ON THE EPISODE INFO. (then he finally shows)

  4. I use a Sony 5.1 surround sound and the new Apple TV has managed to disappoint me here as well.

  There is a mode in my system, when he receives his stereo, he mimics the sound surround. Not radically but subtle.

  THE AUTO SURROUND SOUND DOES NOT WORK. If you leave it in automatic mode it buy stereo music playback! NO! You must manually click the STEREO to listen to music in stereo.

  The only thing why I haven't yet because I hope that the updates will fix that and in my opinion, the video quality of the HD content is better than the quality of the Apple TV 3.

  Does anyone have these problems? Is there any fixes for the PROBLEM of the WORK? Why is it so hard for new mountain BIKING to work high display resolution when the former was perfection in this area.

  In addition, it provide an option where the user can change the theme of light in a dark for the interface. Like the option in Mac OS X.

  This Fund white and bright are distracting, bad for the effectiveness of TV and night viewing.

  1. I can now tell me.
  2. Others complained about that too, I don't think it works as expected and will be hopefully resolved in the future. If you have any suggestions that you think might improve Apple TV, you can send Apple your your comments here.
  3. I can now tell me.
  4. In my opinion, it works as expected, but rather that you and many others expect something different. I suspect Apple are aware of this, they have already tinkered with it in the last (and only to date) update.
  5. Regarding the theme of the light/dark, I agree, I don't like the light. If you have any suggestions that you think might improve Apple TV, you can send Apple your your comments here.

• Task Manager Windows has 5 svchost.exe/System cases and 3 instances of YahooWidgets.exe/Owner running in XP SP3

  I did a few recommended lately on the system settings.  I don't remember see these multiple entries above.

  It is normal to have several copies of svchost.exe appears in the Task Manager.  I have 8 right now in the process of execution.

  Important XP Services running "behind" these entries of svchost.exe.  Some svchost.exe process may have just XP Service running behind her, an another svchost.exe process can have several XP Services running behind it.

  In addition, malicious software has been know to dress up like a svchost.exe process to deceive you or sometimes the malware will hide behind a svchost.exe process, because he knows that you won't be able to see it in the Task Manager.

  I don't know what YahooWidgets and do not want to install any YahooWidgets to find out how it works, or if this is normal.

  Thanks to the bad implementation of the MS Answers forums, we know absolutely nothing about your system is always a good idea before troubleshooting to run some respectable scans for malware, then I'll give you some instructions, if you're curious to see what happens behind these multiple svchost.exe process see you in Manager tasks.

  No matter what you use for malware protection, follow these steps:

  Download, install, update, and make at least an analysis full (not at the same time) with these free malware detection programs:
  Malwarebytes (MMFA): http://www.malwarebytes.org/products/malwarebytes_free
  SUPERAntiSpyware: (SAS): http://www.superantispyware.com/

  These comprehensive analyses can take some time, but you really need to run.  SAS will probably be just a bunch of Internet tracking cookies, but you can remove them.  Once you have done at least a full analysis, you can do quick scans in the future to save time and save the analyses complete for when you have more time or are really suspicious of an infection of the system.

  They can be uninstalled later if you wish.

  To help understand your processes svchost.exe and what is running under them, read this article and you will be smarter than the average bear:

  http://www.bleepingcomputer.com/tutorials/tutorial129.html

  You may be able to get clues with what is happening with your svchost.exe process using the Task Manager and maybe understand.

  You will always be able to understand what is happening with your svchost.exe process if you use Process Explorer.

  Download Process Explorer, so you can see what is 'really' running on your system, especially behind those svchosts several process see you in the running task manager.

  Download Process Explorer from here:

  http://TechNet.Microsoft.com/en-us/Sysinternals/bb896653.aspx

  You'll like Process Explorer when you get the hang of it.  Process Explorer is the Manager of Windows taskbar on steroids.

  Process Explorer installs nothing so it won't slow down your system since it works only on request.

  Process Explorer can seem a little intimidating at first because it has so much information, but you will begin to make love the way it works when you're looking for performance problems.   You can even say EP you want it to be your new default 'Task Manager' value in the future.  You can always run the original tasks as Manager.

  Once you get Process Explorer running, expand the columns, made drag the corners of the screen for it's largest, etc., so you can see as much information as possible in the window.  Now you can really see what is running on the system.

  Hello

  No saving necessary data and re-installing Windows Vista might be the best option, but here
  are a few others.

  You can save your files by putting the drive in another computer as a 2nd disk (best) or external
  Drive USB enclosure and then backup to removable media such as CD, DVD or other USB drives.
  Of course a real store of the computer or the manufacturer of your system can help to recover the files.

  Or you can use a boot Ubuntu CD to back up data.

  Use Ubuntu Live CD to backup files from your Windows computer dead
  http://www.howtogeek.com/HOWTO/Windows-Vista/use-Ubuntu-Live-CD-to-backup-files-from-your-dead-Windows-computer

  --------------------------------------------------------------

  You can access Mode safe? Repeatedly press F8 as you start? If yes you can try Control Panel - device
  Manager - graphics card - Double click on - driver tab - click on UPDATE driver - then right click
  on devices and UNINSTALL - REBOOT.

  A method to try to get to the desktop (try in normal Windows Mode without failure) is CTRL +.
  ALT + DELETE - Manager tasks and tab process EXPLORER.exe and COMPLETE the PROCESS on this subject - and then
  on the Applications tab - lower right - new task - type in EXPLORER.exe. Safe mode is available by
  repeatedly tapping F8 as you start. CTRL + SHIFT + ESC also begins the Task Manager.

  First check this thread in case it is simple and if not to come back to this thread.

  Black screen problems are extremely difficult to repair and all patch is usually on a base hit or miss.
  That there is no information on a black screen as it is on a blue screen just adds to the
  Difficulty. Often using a restore point or Startup Repair will have no effect. You can try a
  Google to see the proposed repairs, whom some have worked however these cover a wide
  field efforts.

  Here's a video of one of them.

  You have a Vista disk? You can try restoring the system to it. If you don't have the disks your
  system manufacturer will sell them at low prices. Or try in safe mode if you can get there.

  If necessary and you can access all ordinary Windows.

  You can try an In-Place Upgrade (hopefully save programs and data) or a repair installation
  (if all goes well, the data records and need to reinstall programs). Be sure to do a good backup or three.

  You can use another DVD that aren't copy protected but you you need to own
  Product key.

  On-site upgrade

  If nothing works, you can make a repair facility that must save the data but you will need to
  Reinstall the programs. This also requires correct Vista disks especially for OEM versions. You will be
  need to know your product Code.

  Another method that works sometimes: at the command prompt, type of Vista startup disk:
  (a line type or copy and paste one line at a time and hit enter - enter a bracket)
  or "BOLD")

  c:

  cd\

  CD c:\Windows\System32\winevt (there is a space between cd and C :)

  Ren LogsOLD Logs (there are spaces between ren and newspapers and Logsold)

  RESTART Windows

  I hope this helps.
