• Insert time consuming

  I have an insert query that inserts into a fairly small table which takes up to 3 minutes to complete. The table has only 52 k in there files. Other tables in this database can be inserted into at least 1 second.
  
  Race explain the plan on the insert gives only 1 line which is not very useful and which basically said the execution should be very fast.
  
  My question is, if I really want to get to the heart of oracle 11g and debugging, what should the tools that I use or what should I look at to know why this insertion takes so long?

  If you can, turn off the trigger, then check the time of insertion.

• Events of waiting "log file parallel write" / "log file sync", in CREATE INDEX

  Hello guys,.
  my current project I'm running a few tests of performance for oracle data guard. The question is "How LGWR SYNC transfer influence the performance of the system?"
  For the performance of the values, that I can compare I just built a normal oracle database in the first step.
  
  Now I perform various tests such as creating index 'broad', massive parallel inserts/validations, etc to get the marks.
  
  My database is an oracle 10.2.0.4 with multiplexed on AIX log files.
  
  I create an index on a table of "normal"... I have run "dbms_workload_repository.create_snapshot ()" before and after the CREATE INDEX for an equivalent period for the AWR report.
  Once the index is built (round about 9 GB), I made an awrrpt.sql for the AWR report.
  
  And now take a look at these values of the AWR

                                                                     Avg
                                               %Time  Total Wait    wait     Waits

  log file sync                           293     .7           4      15       1.0

  How can it be possible?

  -> synchronization of log file: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/waitevents003.htm#sthref3120

  Wait Time: The wait time includes the writing of the log buffer and the post.

  -> log file parallel write: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/waitevents003.htm#sthref3104

  Wait Time: Time it takes for the I/Os to complete. Even though redo records are written in parallel, the parallel write is not complete until the last I/O is on disk.

  This was also my understanding... "log file sync" wait time should be higher than the 'parallel log writing' timeout, because of, it includes the e/s and the response time for the user's session.
  I could accept it, if the values are near each other (perhaps around 1 second about altogether)... but the difference between 132 and 4 seconds is too visible.
  
  Is the behavior of the log file sync/write different when you do a DOF as CREATE INDEX (maybe async... like you can influence it with COMMIT_WRITE initialization parameter?)?
  You have no idea how these values born?
  
  
  Ideas/thoughts are welcome.
  
  Thanks and greetings
  

• I can't sync my Iphone 6

  My iphone and itunes are both up-to-date regarding their updates, but my phone syncs with my laptop. I need help.

  Sync your iPhone, iPad or iPod touch with iTunes using Wi - Fi connection

  Use iTunes to synchronize information on your iPhone, iPad or iPod touch with your computer by Wi - Fi.

  This article is for syncing with iTunes using a Wi - Fi connection. You can also sync your iPhone, iPad or iPod touch with iTunes via USB.

  Synchronization allows you to share information between devices. For example, if you buy a movie on your computer, you can synchronize to add the movie to your iPhone.

  When you sync, iTunes determines if your computer or your iOS device has the latest information. Then you can choose what you want to synchronize.

  Configure iTunes to sync your device iOS over Wi - Fi

  1. Open iTunes. Make sure you have the latest version.
  2. Use the USB cable supplied with your iOS device to connect it to your computer.
  3. In iTunes, Search, then click on your iOS device.
  4. On the Summary tab, select "synchronize with this [peripheral] by Wi - Fi."
  5. Click on apply, then disconnect the USB cable.
  6. Choose which items you want to synchronize, and then click on synchronize.

  When the computer and the iOS device are on the same Wi - Fi network, the iOS device appears in iTunes. Device iOS automatically sync every time it charges and iTunes is open on the computer. Learn more aboutwhat you can synchronize and how to synchronize specific items. You can also synchronize your device iOS via USB cable.

  Get help

  If you cannot set iTunes to sync over Wi - Fi, or if synchronization does not work:

  1. Restart your computer and your iOS device.
  2. Make sure that your computer and your iOS device are on the same Wi - Fi network. Synchronization does not work on an Ethernet to a Wi - Fi connection.
  3. Check your firewall settings. If you are using security software or a firewall on your computer or your router, you can get help with security software. You can also contact the router manufacturer or consult the documentation to know how to open the ports TCP 123 and 3689 and UDP 123 and 5353.

• I unlink my sync but now I want to synchronize my firefox now to the device, how?

  I untie my sync some time before, but now I want to synchronize my firefox now to the device, how?

  Oops, I forgot you were on Firefox 25.

  The recovery key should appear in the Manager password next to chrome://weave (Mozilla Services encryption key)
  

  Please note that Sync for Firefox 28 and earlier versions is not available for much longer, it is gradually from the version of Firefox 34 (14 Oct) or slightly later.

• Sync does not work on all my favorites, only a part.

  31 of Firefox with a new MacBook Air, but the sync of my iMac is not complete. I have disconnected and turn it back on and tried to sync several times. When I go to display all bookmarks on the MBA, they are still missing. Curiously, the folder of bookmarks on the look of the way MBA in records on the iMac - left external and external good records are missing. Any ideas? THANKS, Ben

  Hi benlev,
  I understand that some of the bookmarks are missing when you synchronize to a new computer. I understand you tried to synchronize now and remove the account a few times. However, I do not understand the left outside and external files missing when you look at the folder where the files are stored right?

  You synchronize a mobile device? It may be in mobile bookmarks folder.

  The network for Firefox sync problem was just determined, you see the error messages: "unknown error occurred"?

  Looking for a bookmark missing in "Show all bookmarks" shows the bookmark after waiting for the initial synchronization complete?

• problems updating iPod Touch iTunes sync and lists 9.3.2,and playback on the iPod

  I updated the iPod touch and iTunes and as a first step, I lost all my library because the update iTunes but that is fixed, I had back ups. But when I synced my iPod touch, I had to delete and synchronize the contents of my iPod which has ruined all my playlists in iTunes in sync because the iPod could synchronize only half of the songs because of the error 54. Who sets, restarted the laptop and iPod but because of this, the iTunes playlist had the sync iPod songs. Fixed by re sync several times, I'm always short 4 songs on my iPod to my main playlist but some songs that appear on the iPod do not play, I can choose them but they do not play then shows no played piece. When I get a song to the playlist which works module to the top next just shows that the song only, even if it has been selected by the Shuffle Playlist button. Also some songs on the iPod is not the correct album cover, I'm guessing because of error 54 *, and these songs are often unplayable. All right back on iTunes is just the iPod for now.

  The following steps below should fix things, assuming that all the content you want in your library.

  (If it is not see recover your iTunes from your iPod or an iOS device).

  1. Backup device.
  2. Restoration as a new device.
  3. Restore the backup that you made earlier.

• Re: Satellite L10-90 - time settings are wrong if I start the next computer

  Hi, I have Satellite L10-90 with XP Home. The time setting is always bad for about a month. I synced the time and it seems to be fixed. But if I start the computer the next day, the time is wrong again. I found some information in Google. Some people say that the battery on board already is discharged and must be re-read by a new one.

  I don't know what could be the reason. If I need a new battery, where it is on this computer, and how to change?

  Help will be appreciated.

  Hello

  Normally if you leave the AC adapter plugged the CMOS battery will be charged. If the AC/DC adapter is connected during the night?

  If you have enabled the internet time synchronization time must always bet right.

• Problem about the iPhone 6 s MORE and Ford SYNC (Ford Ecosport) bluetooth pairing.

  Hello Apple community!

  I have an iPhone MORE 6s firmware iOS 9.2.1 running and a Ford Ecosport trend M/T (bought last March 2015).

  I always pair my iPhone with audio system in my car (Ford SYNC) every time I jump in my car every day. I drive 4 hours per day and I'm fond of listening to music with my iPhone through the car radio in my car. But while playing music a few days ago my iPhone just disconnected my car bluetooth device. I tried to pair it several times, but it keeps disconnecting. I switched to the USB mode (I always connect my iPhone to my car for the end of charge and also to listen to music when I want to disable my iPhone bluetooth), my iPhone is connected, but all I hear is static, whenever I play music from my iPhone.

  I tried to delete my audio system phone master reset Ford SYNC and bluetooth devices list and also reset my iPhone, but it still shows the same results. I would appreciate anyone's response on what I live now.

  Thank you so much in advance!

  PS: I already upgraded my iPhone iOS firmware to 9.2.1 before that happened.

  Kind regards

• Can I drag and drop files from my Mac in the time Capsule to free up space on my Mac?

  I currently use my Time Capsule in sync with Time Machine as a return "where" upward... I would like to know if I can drag and drop files to transport CANADA to free up space on my Mac.

  I would like to know if I can drag and drop files to transport CANADA to free up space on my Mac.

  Yes, but the fact that you can do something does not suggest that it would be wise to do. Please take a minute to think about it per.

  If you delete files on your Mac for free space and move them to the TC... so that only one copy of these files you will be on the TC.  What will happen to the files when... not if... you have a problem with the TC?

  A plan much better, faster and more secure would be to add a USB to your Mac and move your files there. Then, Time Machine can back up your Mac and the USB attached to your Mac to the TC.  It would be a minimum backup... plan your files 'master' on the USB drive and 'backups' on the TC.

• Vertical sync to the temporal position of two or more systems 2D axis?

  Tiara in: REVIEWS,.

  Is it possible to vertically sync the time position of two or more cards of 2D axis system placed over the other?

  I have posted several channels on a 2D graph and a channel of particular interest on a separate table above, that was very easy to do. It would really help synchronize time on the two charts position, such as a scrolling graph also scrolls the second table, or zoom graph also zooms in the second picture of the same area, which seems to be a pretty basic thing you want to do, but I have not found a way to do it again.

  Any help is greatly appreciated!

  JohnGrove salvation,

  Actually, yes we CAN do it-if you have DIAdem 2010.  There is an example called "Alignment of the functions in DIAdem VIEW" delivered for the first time with DIAdem 2010.  When you run this example, you will get a new Star ' * ' icon in the top right corner of the Panel VIEW.  Click on the new icon for a collection of functions of alignment axis which I think will make you happy.

  Let us know,

• Possible bug-> CompactDAQ synchronization between HAVE and counter - sync error depends on the sampling frequency (exactly).

  I have a system with a map of the 9234 compactDAQ 4 Groove and a 9401 in slot 5.

  I use a function generator to create a 5V square wave frequency sweep.

  The frequency of scans from 1 Hz to 10 Hz in 3 seconds.

  I have this tee in my door to counter 0 (PFI1 - 16 Pin) and an analog input channel 0.

  In LabView, I do a period measure counter that has a trigger defined on the trigger to start ArmStart HAVE.

  Piecemeal the signal into two channels, I see the time counter correspond to zero-level positive slope crossings in the data to HAVE it.

  By the presence of a square with a mutation frequency wave, I know for sure that the time is not out of a period.

  I noticed the downturn to take samples, the greatest moment of the synchronization error.

  Here is the data that I have saved:

  sampling rate 1 / (sync error times)

  51200 1250

  25600 625

  10240 256

  2048 51.8

  1651 37

  It worked of Y = 0,0244 X + 1.1262 with R ^ 2 = 1.0

  So it could be, I have a programming error, or that there is a bug in the hardware or the base software.

  Thanks for any help to understand this question.

  BTW, I use this system to make an analysis program in the stopped vehicle with direct sequence over time - of course analysis based on the revolutions.  I found that order analytical tools was not flexible enough for what I had done, so I started from the ground upward.

  Hi Greg,.

  Looks like you see the entry delay the NI 9234 (Group delay).   As specified in the instructions for use NI 9234, entry delay is equal to 38.4 / fs + 3.2us.  This is because of how the sigma delta ADC works - after the start, it must acquire a certain number of samples before returning the first valid sample.  This delay is expected.

  Here is a knowledge base on the subject.  There are a lot more, just do a search of the knowledge base for "group delay.
