Registration of the undo history

• Changing data in the undo tablespace or db Oracle buffer cache

  Hello
  
  I have serious doubt in the feature of oracle architecture, when a user issues an update statement, the data blocks are transported to the db buffer cache and where the data changes are made? Made a copy data block is stored in the cache db pads and the changes are made to the block in the buffer cache? or the copy of the data block is stored in the undo tablespace and changes are made to the blocks in the undo tablespace?
  
  In singles, the changes to the data blocks are make to the db or undo tablespace buffer cache?
  
  
  Thanks in advance
  
  Kind regards

  Did you have a look to the Internet for the answer?

  In short, if a trial Oracle wants to update a record in the table, it does:

  -Read the record to be changed in the buffercache
  -Audits (the record already locked, is the update allowed)
  -Put the folder (called image before) in a rollback in the UNDO tablespace segment
  -Writing redo information about this change in the UNDO tablespace
  -Lock the record
  -Write the change in registration in the buffer cache
  -Put the change also in the redo buffer
  S ' sit and wait... (for a commit or a rollback)

  When are committed:
  -Release the lock
  -Empty folder of restoration since the UNDO tablespace
  -Write a record of this change forward in the UNDO tablespace

  When rollback:
  -Release the lock
  -Rinse the record changed the buffercache
  -Read the original value
  -Empty folder of restoration since the UNDO tablespace
  -Write a record of this change forward in the UNDO tablespace

  It of here, some more specific complexity when a checkpoint occurs between the change and the commit / rollback or redo buffer has been emptied for redo files

  Please any other s/n, correct me if I'm wrong...

  See you soon

• Top sites and the browser history

  Hi, I'm on a Macbook Pro 2011 running OS X Yosemite 10.10.5, with several people using my login information. My question is - I have a site on my Top Sites, but when I look in the browser history I don't see. This means that the browser history was deleted? And if it appears in the Top Sites does this mean it has been visited frequently or not necessarily? Thanks v. much.

  Not necessarily. It is possible to add a site to the Top Sites with the add a bookmark function (inadvertently).

  Cannot find a rope in order to delete the browser history.

• In the last Firefox where 'browser.download.panel.removeFinishedDownloads' no longer exists, how it automatically erase only the download history

  In the light of the latest Firefox and the fact that he's not listening my download affected the retention setting and that 'browser.download.panel.removeFinishedDownloads' no longer exists, how can I clear history of downloads automatically after each download without clearing the browser history too? If this isn't an option it's a serious bug or an important feature removed. If the problem persists, it is a big reason for me to stop using firefox. Really guys! Why?

  Add-ons - make it flexible and "configurable by the user.

• TV purchased not appearing is not in the purchase history

  I have a family account set up. Child has launched series TV purchased on his iPhone. TV shows are on his iPhone and I can't go in the purchase history on my iPhone and my iTunes on my MBP and television programs are there. The only place where purchased TV shows do not appear in the purchase history is on the Apple TV. When I go into the TV shows on Apple TV, I go to his profile family sharing and some of the TV shows he bought on his phone appear on Apple TV and other.

  I wonder if there is a timing problem with the Apple TV to reach out to the servers of Apple and grateful TV bought watch as actually purchased.

  I disconnected (e) my AppleID on Apple TV and the back signed in as that sometimes resolved hiccup like this in the past on my other devices, but not lucky this time.

  It's on the Gen 4 Apple TV, model 64 GB (A1625) tvOS 9.2 build 13Y234. iOS devices run 9.3.1 and my iTunes is running 12.3.3.17.

• How can I clear the browser history

  the browser history is cluttered with attempts to find mforation over several days. I want this clesr off.

  Hello

  There are two Add-ons you can use with Firefox Mobile to clear your history (Cleary and erase the historical Mobile).

  If you press the menu button on the device and select Add-ons, you can search for and install an add-on. Then click on Preferences in the menu and scroll to the bottom to see the button clear history.

  Here is an article with step by step and screenshots for tablets (the steps are the same for a mobile phone, except that the menu button that you use is the one on your phone).

• The sidebar will not clear history, even after deletion of history, how to erase the sidebar history?

  Even after the erasure of history (FireFox 6.0.2) the sidebar history contains a story of friends.

  After you remove each item individually and say things to forget to each site, they all return.

  Any ideas on how to clear the history sidebar?

  One possible cause is a problem with the places.sqlite file that stores the bookmarks and history.

• How can I see the arrow button that showed the recent history of a same tab (next to the buttons next and previous)?

  for example, if I searched word on google, then clicked on a page of results, then inside this page, I entered a link, etc if I wanted to 'go back' directly to the instance of google search I could click on the arrow button and I would be able to choose this exact moment instead of click the 'back' several times until I reached the desired past page

  The arrow to open the history tab of the previous buttons and following was removed in Firefox 4 and later versions.

  Use one of the following methods to open the tab history list:

  • Right-click on the back or next button
  • Press and hold the left button of the mouse on the active back or forward button until the list opens

  You can watch this extension:

  • Backward forward history Dropdown: https://addons.mozilla.org/firefox/addon/backforedrop/

• Firefox used to have an option on the next to the forward/backward buttons navigation bar that showed the browsing history - I could come back ten screens without hitting the button back ten times. Is the new version has this feature? If so, how can I a

  It was a triangle button, which provided a drop-down list of my most recent history within a site. Very convenient, esp for slide shows if I wanted to return to a slide that was 10-12 rear blades.

• Firefox does not store the browing history

  Several weeks ago, I deleted my cache to solve a problem. Since that time, Firefox displays the last ten websites I went on the drop-down history menu, but when I click on view history, the window is empty and says 'no element' downstairs.

  I have studied this problem on other sites and those provided by other troubleshooting tips:
  1) ensured that the tools: Options: privacy is defined on do not forget history
  (2) ensure that private browsing is not enabled
  (3) typical subject: Config in my address and verified field as all the parameters: the browser history are by default (180 days; 40 000 objects)

  I'm sure that it is a simple value somewhere, but I'm out of ideas. Can someone give me a hint?

  If the menu history displays the elements of the story then that suggests that the story works correctly.

  This may be a problem with the places.sqlite file that stores the bookmarks and history.

  "Save history" set to 30 days but can only view last 7 days of history - how can I view the longer history of 7 days?

  According to your troubleshooting info, you have 2 set preferences to update the:
  Browser.history_expire_days
  7

  Browser.history_expire_days. Mirror
  7

  In the address bar, type Subject: config and press ENTER. The subject: config "This might void your warranty!" warning page may appear. Click on that I'll be careful, I promise! to continue on the subject: config page.
  Search for the preference browser.history_expire_days. Right-click on it and select reset. Do the same for other preferences.
