• Number of blocks of Table

  Hello

  I have a table T, and it has 30 rows.

  I put the command:

  Select

  Count (*) "number of lines"

  DBMS_ROWID. ROWID_BLOCK_NUMBER (ROWID) 'block No. '.

  Of

  t

  Group

  DBMS_ROWID. ROWID_BLOCK_NUMBER (ROWID)

  and Oracle gave me the block number 663 that all rows are in the block.

  Also, I used user_tables, dbms_space.space_usage, dbms_space.unused_space

  to check the number of used blocks and the number of unused blocks

  The result makes me confused because the number of blocks in rowid_block_number() - 1 - is different

  from user_tables, dbms_space.space_usage () - 5.

  If 5 is the correct number of blocks, why isn't the value of the empty_blocks column in user_tables 3?

  (The total in table T blocks would have the value 8, according to dbms_space.unused_space (),

  and blocks are 5, so 8-5 = 3)

  Can someone tell me the difference in the value of the blocks, free blocks and total blocks between the view and the functions?

  Thanks in advance.

  

  

  Under Oracle SAMS usually formats 16 blocks at once, but since you use the allocated system extensions the first measure is only 8 blocks so the whole extent is formatted.

  As the 1 degree in the segment, the 3 first blocks are the space management (level 1 bitmap, bitmap image in level 2, segment header) leaving you 5 blocks that are formatted and 100% free space and you have then inserted you stored in the pseudo (-) randomly selected last block of scale - leaving you with 4 blocks to 100% of free space and a partially filled block.

• Partitioning and Clustering of Table

  I just inherited a table with 10 million discs. Data can be grouped against a key, every key with usually around 10-200 lines.
  
  Given against this key gets dragged over a large period of time. The separate keys in this table at present are ~.7 million.
  
  All our access to this table is based on this key. As you can image data are scattered in several blocks, so there is considerable I/O and it takes a long time for all queries to run. Ours can be described as instance Reporting however inserts and updates this table up-to-date produce 24/7 and access to the system is 24/7.
  
  My question is threefold
  
  Should I create a cluster from the unique table on that table with my key as the cluster column?
  
  Partitioning coexist with clusters?
  
  Other strategies exist to optimize in this case?
  
  Thanks in advance
  
  Daniel

  If each key corresponds to 10-200 lines, however, and it is a regular b-tree on the key index, the fact that there are millions of rows in the table should be (mostly) not relevant - Oracle will get 10-200 ROWID of the index and 10-200 one-piece extractions. This should be pretty quick, so I'd be interested in why you think that this distribution is causing significant delays in reporting instance.

  Are you a license for partitioning (it's an extra cost option on top of your enterprise edition license)? If you are partitioning table would seem reasonable. A cluster of the unique table or a table in index also seems to be reasonable. Cluster table, however, will slow down inserts and updates. However, you cannot partition a table cluster.

• How to stop people at random me to add and block instantly?

  I get people to randomly add me and when I remove them he gets very annoying to have to go through and block them. I normally get 4-5 a day and Im not really sure where they're getting my name of? Any help?

  Noone you can add if you agree to the request. Contact requests are open design, so that anyone can send a contact request, however they do not add you as a contact if you agree. This is how most of the messaging software and Skype works. Skype is as an open directory anyone can search and find you (if they know how).

  You can however reject and block any communication of the additional requestee. You should also review the tools > settings > privacy and make sure everything is set up as you like.

• incompatibility of time information and block length

  This seems to be a regular problem.

  But I couldn't solve it in other cases in the forum.

  I get error when I try to run the program:
  "The duration of block or the information of the input channels does not match...". »

  The program complains to my switch to Signal named 'Signals ADAPT' (see photo). I use V.11.

  The thing is that the problem comes and goes. I've adjusted the program/system able to install 2000 Hz and block of length 1.

  Everything worked fine until I copied the program on a server and then use the file to another PC, from the server.

  Usually I make it work when I change the length of the block and then again. But it's just a quickfix.

  I tried to trace all the wires (who worked for another file) and replaced with new modules.

  The control signal is of dasylab blocks and signals to pass to an NI USB-6501.

  I use a time delay module to be able to run the parallel workflow. If they collide in time.

  Now I had headaches... Please help

• Parental control: I am the admin of the computer and the computer won't let me access the list allow and block my child's account

  I am the administrator of the computer and the computer won't let me access the list allow and block my child's account.  I'll bring my parental control password, click on my childs account, put parental controls, go to web filter and click on block some web sites, click on edit the allow and block list and the computer tells me that it is not able to make changes to parental controls settings and see the system administrator if the problem persists.

  Hi Ranw,

  ·        What is the error message when you try to change parental controls?

  ·        Have you been able to make any changes on this computer from your account earlier?

  You can follow the steps below and check if you can make changes to the parental controls on your computer.

  Step 1:

  Disable UAC (User Account Control) and check the result. Access the link below and follow the steps to disable UAC.

  http://Windows.Microsoft.com/en-us/Windows-Vista/turn-user-account-control-on-or-off

  Note: You must restart your computer when you enable or disable UAC. Change levels of notification does not require that you restart your computer.

   

  Step 2:

  I suggest to create a new administrator account and log later in the new administrator account, try to set parental controls and check if it works.

  Create a user account:http://windows.microsoft.com/en-US/windows-vista/Create-a-user-account

  Check out the link below to check if the parental control is properly set:

  http://Windows.Microsoft.com/en-us/Windows-Vista/set-up-parental-controls

  I hope this helps. Let us know the result.

  Thank you and best regards,

• unknown sender - delete and block - permit sender - duh...

  Show all emails in my "SENT" folder as "unknown sender - delete and block - allow the sender.

  duh...  Of course, I could push 'permit sender', but I don't want to push a button because some programmer is a fool.
  Or maybe, I could push DELETE AND BLOCK.  I don't know what could happen?  Vanish all of my sent messages?  I would be able to send messages to myself.
  Several years ago I said to HOTMAIL, it was safe to receive messages from myself, who at the time was pretty ridiculous, but I did. However, it seems that Windows Live has the same problem...
  so... I opened my mail in HOTMAIL, I send a message to myself (* address email is removed from the privacy *) and it goes thru.  I have all mail from unknown senders blocked for my balls. It comes to my Inbox.  I check with Windows Live Mail, the message is in my Inbox.
  but... Sent in my folder? It says "unknown sender - delete and block - allow the sender.
  Double duh...

• How can I control the Tasbar? It is always in sight and blocks the screens of other programs.

  How can I control the Tasbar? It is always in sight and blocks the screens of other programs. Using Windows 7 and Microsoft Security Essentials. "Lock the taskbar" is checked and "Auto-hide the taskbar" is checked. Help, please.

  Taskbar will appear to take with you when you either come from anywhere near the bottom of your screen or a security alert is displayed.

  The best I've found is to use the fullscreen with F11.
