• What is the meaning of the optimizer based on CSSTidy referring "A ORDERED USE_NL" Please?

  Hi all

  What is the meaning of the optimizer based on CSSTidy referring "A ORDERED USE_NL" Please?

  I searched the internet without great success (indicators of optimizer). Can you please enlighten me on this? Thank you.

  My problem is that it works well on a database and another data base, it is really slow.

  Kind regards

  Michael.

  If the inner table's access path is independent of the outer table, then the same rows are retrieved for every iteration of the outer loop, degrading performance considerably.

  Can you say: join Cartesian?

  This quote is from the section explaining the nested loops. and note it gives you a clue:
  >
  See also:

  "Cartesian joins.
  >
  The sentence BEFORE the one you quoted, it is what connects your quote with the MENTION:

  It is important to ensure that the internal table is driven out of the external table (function).
  >
  This statement means that the lines of the internal table should DEPEND ON the external table.

  In a Cartesian join the inner table will depend on the external table at all:

  SELECT D.*, E.* FROM DEPT D, EMP E
  

  There is no WHERE clause, so there is nothing saying Oracle tables are related as well. Oracle will perform a Cartesian join and if a nested loop is used then, as says your quote, "the same lines are retrieved for each iteration of the outer loop, performance degradation significantly."

  All Oracle ranks visits to query external table lines will now be the inner table. But because there is no WHERE clause is no available information to EXCLUDE lines from the internal table "the same lines are extracted" (ALL) "for each iteration of the outer loop.

  Here is the same query above using the USE_NL hint to force Oracle to use a nested loop

  SQL> select /*+ use_nl (d e) */ d.*, e.* from dept d, emp e;

• What is the meaning of the colors in the business plan?

  I used the Apple Watch 2 series for the first time during jogging. IM wondering what is the meaning of the colors that appear in the map I've seen since the implementation of the activity in the report of the training session. Anyone know?

  Hello

  Line color reflects your speed (green being faster, the Red being slower).

• What is the best solution when my external drive for Time Machine is full?

  Hello

  I use the latest version of Mac OS X on my iMac 27 ". I use a drive outside of 3 TB G-Tech for Time Machine backup. Due to my recently many RAW photo images, I have less 8% left storage on my external hard drive, so I'm trying to figure out next steps in what concerns the strategy of external storage and have the following questions:

  • When my external drive for Time Machine is full, it is my understanding that older backups on external hard drive will be deleted to make room for newer backups. If the oldest backups contained pictures (whose records have not changed since the time they are initially stored), then I guess that these photos will be removed from the external drive - correct?
  • If I had to replace my external drive for Time Machine with a new external drive which is as big or bigger than the one it replaces, what should I expect on the size of the initial backup on the new drive? I guess the size of the backup would be exactly equal to the current amount of storage used on my drive hard iMac - correct?
  • Would it not be possible to connect the external drive for Time Machine existing at a new Time Machine external drive so that when the original disk is full, the overflow will be automatically stored on the new external hard drive for Time Machine? (If feasible, it seems that this strategy would maximize my external storage capacity vs just replace external drives.)

  I realize that my first two questions are rather basic, but I don't want to make any false assumptions. The third idea is intriguing and I would like to know if this is a viable option.

  Thank you

  Brian

  older files are starting to get deleted because the disk fills up then Yes, they went

  the backup drive should ideally be 4 times the capacity of your current drive, twice is good but has its limits. Also factor in what you store: a jpeg from the web and a raw photo file are the two images, the size of a is very different. If you work in high-resolution or large native files, or audio files (record pro, no music files) or video production twice the disk fills up very quickly. If you collect photos and JPEG and mp3 files or a handful of videos not so much is necessary.

  I would keep the old drive intact if you want to replace and start over with a new drive, if that's the plan. You have the old data, you can keep it somewhere safe and have a redundant backup which you can reconnect at any time to restore from. Let the new index drive itself with new data and take if from there, in the case otherwise you can copy the backup to the new drive and set the drive as the new source of backup but personally I wouldn't copy of the data, that's my preference, it may not be yours and that's fine.

• What is the meaning of the red dot with the number 1 for me for reset?

  airport utility is open on my screen there's a new red dot now displayed a number 1... When I click on this a dialog box appears asking me if it's ok to reset?

  I do not bother with the machine. I walked over to my office and found the screen as shown above.

  The Red badge is a notice that a new firmware update is available for your router AirPort.

  Click on the Red badge, and another window opens with an update button.  Click on update, if you want to.

• No problem. What is the meaning of the spinner counterclockwise in tab, spinner clockwise vs? Transmission and reception?

  No problem, but a question: what is the meaning of the Pan anti-clockwise in the tab, vs the arrow to the right? Is it in the opposite direction when sending to the cloud and to the right at the reception of the Cloud?

  Thank you

  I think it's this way:
  
  needles: rising site in domain name registration and to establish a connection to the site.
  
  clockwise: actually receive information from a site and building Web page

• What is the best way to backup a hard drive full of pictures and videos on another external hard drive?

  What is the best way to backup a hard drive full of pictures and videos on another external hard drive? I want an exact clone-

  Drag and Drop? Time Machine?

  Thank you. DB

  If you want an exact clone, you will need to use a utility like utility disk, Carbon Copy Cloner or SuperDuper!

• Toshiba Canvio 1 TB HDD - what is the meaning of blue-white LED

  What is the meaning of light blue or white light flashing on this HARD drive?

  HARD drive seems to work OK whatever color is on.

  Thank you very much

  On my model (Canvio Connect II) the port of blue led lights if connected to a port USB3 and white if connected to a USB2 (and probably USB1). I think the same thing applies to your model too.

• My computer makes a clicking noise at random - in the diagnosis of the Apple what is the meaning of error 4HDD/30 / 40000005:SATA (0,0) Please?

  My computer makes a clicking noise at random - in the diagnosis of the Apple what is the meaning of error 4HDD/30 / 40000005:SATA (0,0) Please?

  Several clues:

  1. HARD and SATA drive in the message... On the way SATA HARD drive
  2. Clicking noise, which is an early signal of imminent death for HARD drive (there are only two types of readers... those who died and those who will be)

  I would like to start keep good clones (CarbonCopyClone, bombich.com, $40) for external drives or backups Time Machine.  Any backup of the drive, not just your favorite parts.  Perform backups on a schedule without fail IMHO.

  You can also start to consider a SSD at macsales.com (their mercury collection is highly recommended) or a new HARD disk, at least start planning if the SSD cost is worth the benefit of speed on the HARD drive.  You can buy it later.

  Just my paranoid approach to this situation.

• What is the meaning of the name of an iso file?

  For example,cn_windows_server_2008_datacenter_enterprise_standard_sp2_x86_dvd_342333.iso and SW_DVD5_Windows_Svr_2008w_SP2_ChnSimp__x86_DC_EE_SE_X15-41045,What's the difference between the two?
  

  For example,cn_windows_server_2008_datacenter_enterprise_standard_sp2_x86_dvd_342333.iso and SW_DVD5_Windows_Svr_2008w_SP2_ChnSimp__x86_DC_EE_SE_X15-41045,What's the difference between the two?
  

  Any ISO file name is just a name.  You can rename this one, for example, for "Windows Server 2008 Enterprise 32-bit Edition with SP2. ISO"and it means the same thing.
   
  If you want more precisely say Microsoft ISOs - well, can extrapolate you from the example?  ;-)

  My question is that why Microsoft name an iso file in different ways? And what is the meaning.

  x86_DC_EE_SE_X15-41045"?I have heard that the former can be downloaded from MSDN subscribtion and the latter is distributed in VOL channel.
  

  Why name a file ISO in different ways?  It's a different ISO file.  Don't forget: an ISO file is simply an image of a CD or DVD.
   
  Also - if you are the one doing the download from a legitimate source, you KNOW what you get no abridged way plain before arriving anyway. by the description.
   
  In any case – why reinvent the wheel:
  http://www.betaarchive.com/forum/viewtopic.php?t=26026
   
  The short of it: it is usually the name of the product in there, the architecture (32-bit or 64-bit), the language (like the comparison you wanted, is a simplified Chinese and other English, because there is no moniker language) and the product part number (which is something useful only to resellers and Microsoft in many ways).
   
  If you don't mind me asking, what is curiosity behind the naming scheme?

  Hello
  • What version of Windows are you using?
  • How long have you been faced with this problem?
  • What were the changes made before the show?
  • What is the full error message that you receive?

  I recommend the clean boot and try to install in clean boot state.
   
  Configuration of your system in a clean boot state helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.
   
  See the following article in the Microsoft KB for more information on how to solve a problem by performing a clean boot in Windows Vista or Windows 7:

  Note: After troubleshooting, be sure to set the computer to start as usual as mentioned in step 7 in the above article.
