• Cost of the execution plan is different in the two databases

  Hi gurus,

  I have two databases, which are 12 C.

  The execution plan cost is different in the two databases for the same query.

  is it possible to copy the execution to another plan.

  Thank you in advance

• Pixel dimensions and how it differs from the size of the file

  Ihave this photographer who sends me a picture of a print document.

  There he cropped to the correct size:

  
  

  But, the image is grainy and I'm afraid it all there just resampled it. It is hung on the fact that it is of 74.6 M in this screenshot, but the file is a JPG of 10 MB. He repeats to me that image must be big enough, because he is 74.6 MB and I do not have "uncompressed" it properly.

  So my question is, how I clearly explain how the Dimensions in pixels of 74.6 M is really different from a file that is 74.6 MB in size and is not really an indication of the image quality in this case? Or am I missing something, is there a way that I have to process this file so that it is high resolution enough for printing?

  Thanks for your help!

  I really want to add to that. An easy way to see what jpeg compression is doing to an image is to enlarge your image and drag the slider down to 1 it does is "lumpy" colors together and in doing so, throwing the color information to get the size down.

  You will see the "tuft" image as the file size goes down.

  It does not change the number of pixels. If you open your file it will be 74 MB, and the pixel dimensions are the same quality 1 or 10 quality.

  But the image will be "sick" to healthy and 1 to 10. You save space, but that's what you get.

  Here's the "liquidation".  If you want to print, download a flat tiff file. In ancient times the modems and readers of 500 MB, jpeg may have made sense, but there are terabyte, DSL speeds and cloud like Dropbox storage disks. It's cheap send a uncompressed file ready to print.

  

• Why image compression information is different on the method used

  The size of the new image is 72 dpi @ size 1280x800px resolution.

  The final output settings target when using "Save for Web" in Photoshop should be:

  resolution of 72 dpi @ 1280x800px dimension

  JPEG quality: 75 @ 246,7 kilobytes.

  1. If I re - upload the image which is supposed to be 246,7 kilobytes in Photoshop, then click on the image size.

  He told me that the image is 2.93 MB.

  2. If you use Apple app 'Preview' and click the Inspector he tells me that the image is 253 KB (kilobytes).

  3. When you use the 'Quick look' feature of Apple, by selecting the image and then press space bar, he tells me that the image is 247KO

  (rounded) parameters of 246,7 kilobytes of output which is closer to the original final goal.

  4. Finally, when I click on order I for the information of the image, it tells me it is 253 bytes or (254 KB on disk).

  Why all these news image available so different and what method do I use or trust?

  Hi Choiceimport,

  Don't sweat the little things. The subtle differences between preview, Quicklook and command-i are due to a variety of things such as sectors how this program could look to get all the data. Some programs cantilevered sector reading. One area where you will see really is if you have saved your image is 253 kb and when you put it in a mail client, it might be (and I do this number upward) 370 KB.

  The big problem, that is why it is so big in PS. To understand this, we must remember that JPEG images are compressed in a lossy format. There are two types of compression here, frozen appearance (because the format actually loses information (ergo with loss), so that more compression, more data is removed and thrown (never to return) and General format compression algorithms.) For example, the file has a size of storage 247KO (or about), but when it is developed, so it can be seen is 2.93 MB. How much is the PS must take care in what concerns the ram to work with the image but not its storage size.

  And FWIW, I specifically call on "storage size" by referring to the size of the document is on the hard disk, as opposed to the size of the image that is (for me) refers to the dimensions of the image (either MPXL or X pixels wide by Y pixels maximum).

• What is the use of FPGAS and how it differs from the IO Modules

  Hi all

  Maybe it's a silly question for most of you.  But I have very less knowledge about the basic concepts of electronic (FPGA, real-time) to cRIOs. I know that FPGA

  can be used to generate circuits within the chip that helps by some logical functions.

  I've just started working in the cRIO.  My question is that we have Modules e/s making it outputs all the application entry.  So, what is the purpose of e/s in the FPGA.

  Lets consider that we entered for an application of RTD.  In this case the module NI 9217 itself exits 24 bits of data from the RTD measurement which may be the process of the LabVIEW VI.  What will be this FPGA between the i/o Modules and the processor will help in?  Also I want to know what type of communication is used to send data between the FPGA and host modules.

  Thanks in advance

  Ajay HI:

  Sorry, you do not have an answer to your original question. However, you are right about the benefits of the FPGA. You said, if you build pre-processing in the FPGA, you can unload a lot of potentially CPU calculations out of the host processor. In addition, the program running on the FPGA is highly deterministic and can run the code very quickly. So if you build a kind of guard or evanescent dog part of your application, the FPGA is a good place to put it.

  To answer your other questions, communication between the modules and the FPGA is generally above the SPI and the data can be transferred between the FPGA and host via DMA FIFO operating on the PCI bus or single point save access using read/write in the FPGA host Interface controls. You can also use interruptions in signal of disputes between the FPGA host.

  I hope this helps, but let us know if you have any other questions.

  Create a database user has access SELECT through patterns. Then, use a Pool of single login with this user id and check the box to fully qualify table names, so that when the SQL generated it precede patterns correctly. You can create patterns according to the needs, and it will work fine.

  Thank you

  NO, you don't have to copy the srf tools file to the location of the customer.

  just when compiling your project or changes you must click on the Browse button and navigate to the customer i.e. srf "/ web client/objects/enu/siebel.srf".

  but before, also compile all projects to the strategic outcomes of the client.

  the other thing you should check is client and tools should point to the same database that you should check the cfg files of the two respectively in [[example]] section connectstring = "\sample\utf-8\sse_samp.dbf."

  no doubt, maybe that's the problem.

• Suggestion: Subcategory "Security" of the category "Database".

  Hi all
  
  I managed to find that on OTN Discussion Forums, there are:
  Java-> category: security
  Technology-> Forum: security
  
  and technology: security questions apply to the Oracle database software.
  
  I always wondered why there is no 'Security' subcategory in the category "Database" (http://forums.oracle.com/forums/main.jspa?categoryID=84)
  I have read security of database on discussions in the 'Database - general' sub-category of category "Database" and always had this strange feeling of a subcategory of 'Security' missing.
  
  In my view, security of database threads would be better organize you if there a subcategory "Security" of the category "Database".
  
  Thank you

  I think there is a forum of database security - general , although it is rather well hidden at the bottom of the list of database instances.

• Aggregation in the ASO database view

  Hello world

  I am trying to create a new view of aggregation for the combination of members (Level0 and high level members) on the ASO database. Not sure to create the aggregation process.

  I poured the current view_file using the "validate a global selection on dump Appname.dbname database to view_file 'MYVIEW';'. ...

  But, how can I change this file in my combinations of members... I went through some documents, but I have found no solution for my problem...

  Could someone help me pls with this one... (With steps would be very useful)...

  Thanks in advance!

  For the better or the worse, Oracle did not have what you want (create a view for a specific set of levels) easy.  The only guaranteed way to force creation of a view to a particular set of levels is to reverse engineer the algorithm which translates integers found in the file .csc views.  I did, but I do not recommend it particularly.  Alex Pavel deserves to have a translator to work entirely online, here: http://essbase-ish.blogspot.com/2014/02/custom-built-oraclehyperion-essbase-aso.html

  I also had success with the following query "cheats", using advice outline etc..  More on these techniques in this 2011 Kscope (mine...) presentation: http://www.odtug.com/p/do/sd/topic=33&sid=709 (free associate member required).

• Discover the composer "database not supported" error

  Try to install View Composer (v3.0.0 - 691993) on my 5.1 SP1 of SQL Server 2012 with vCenter server.

• Installing Vcenter new server with the new database

  Hello

  We currently have the virtual Center 2.5 with SQL express back-end and we are planning to upgrade to vcenter server with Oracle backend. My original plan was to start over by installing vcenter on a temporary server with Oracle and eventually return the current server vcenter and use the same Oracle server. What would be the simplest solution for this? Essentially, in the end, we need to use the current server to vcenter but move from the db to the Oracle database. Our group consists of 3 servers and only active DRS at present (HA disabled for this upgrade). Can I upgrade the current virtual Center vcenter server directly and do fresh install for the Oracle database?

  Thank you

  I would also install a new server vCenter thr.

  After that, make a new configuration and Noor and if everything works correctly, uninstall the old und VC 2.5 check also the HA!

  Good luck!
