  Hello

  The process of database have a file handle for the data file - this remains even when the file is deleted (it disappears from the normal file system navigation)

  You can see if you have lsof installed

  just try

  lsof | grep datafile_name

  Once the database is restarted and the released file handle so you will not be able to do this any more - and in fact you will get errors when it can't find the file.

  See you soon,.

• Privilege for the creation and deletion of the indexes on all the tables/diagrams

  Hello
  
  I have a database running on the HPUnix bit ia64 platform. The version of the db is 10.2.0.3
  I have a schema named DPYBATCH.
  
  I need grant creation/deleting indexes on all the tables/diagrams.
  I know create a clue will solve the purpose of the creation. But I am confused with deleting indexes.
  
  If I give-> GRANT CREATE ANY INDEX OF DPYBATCH, it will not solve the purpose. He will have the privilege to be able to delete/move the index as well?
  If this is not the case, what is the privilege to grant to delete/move the index. Please let me know!
  
  Thank you!

• delete all the records in a table, the speed of insertion is not change.

  I have an empty table, and I insert a record need 100ms.
  During this table a 40,0000 trace, I insert a record need 1 s, it's ok, because I need to make a comparison according to an index before inserting a record need, so more record, more time.
  The problem is when I delete all the record in this table, the insertion time is always 1s, not reduce to 100ms. Why?

  Hello

  Read this part of the oracle documentation

  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14220/logical.htm#CNCPT004

  The reason is always 1s, because when you inserted 400ko record as HWM (high tide is the border between old and new space in a segment.) moved to the top. And when you remove all records of your HWM still in the same coordinate system and that you have not reset to 0. So when you insert 1 it save free space and after finding faces (usually a regular insertions got 6 steps it inserts data). If you truncate your table you and try it again it will be faster that your HWM is reset to 0.

• How imp one table, delete the old data? or the deletion of the table (before)

  Suppose that: in my tcomven of the actual table, I have 15 records, guess also, I have the file: h12292008.dmp there are 27 records
  
  If I type:
  
  IMP TABLES = (tcomven) UFIERROS/linuxx fromuser = UFIERROS touser = UFIERROS file = h12292008.dmp ignore = Y
  
  show imported 27 files, I checked the table and I have 15 + 27 files = 42 Records
  
  My question:
  
  before you import the table is possible delte all the contents of the Tcomven table (note I do first with sqlpleu and or sqldeveloper) my question is exista flag custom imp?
  
  
  or:
  
  If I type (same command ignore without flag):
  
  IMP TABLES = (tcomven) UFIERROS/linuxx fromuser = UFIERROS touser = UFIERROS file = h12292008.dmp
  
  tells me an error: the object exists, same question: the imp command flag for gout have first of all the tcomven of the table (or in any case, at the head of exp e)?
  
  
  Thank you

  Your needs:

  When you use imp (old style) of command line... you must delete/truncate the table before

  If you are using expdp/impdp, there option TABLE_EXISTS_ACTION help 'TRUNCATE' table before.

  TABLE_EXISTS_ACTION Action to perform if any object already exists.

  Valid keywords: (SKIP), APPEND, REPLACE and TRUNCATE.

  The policy function is applied once per execution of the statement. The political function executes first, and the UPDATE statement updates probably, no line because the context is not yet filled. The level of the line fills the frame (I'm assuming that your session may even see context values populated by autonomous transaction - I guess it's possible, but I have to test this) after the UPDATE statement is already complete. VALIDATION in the row-level trigger is also useless - it does that to changes made by the current transaction that is independent, of which there is none--it cannot apply to changes made in the other autonomous transactions. Declaring the level line trigger to use autonomous transactions does not seem to do anything other than to open the question of whether the values defined under the autonomous transaction are visible in the transactions of the appellant.

  Even if, somehow, did not work, the use of transactions autonomous would be a very bad idea because Oracle is free to roll back a partially executed query (and the work done by its triggers) and re - run. Oracle does with some regularity to maintain the consistency of Scripture.

• Disk HARD drive deleted in the Finder and now appears

  My macbook pro has two hard drives, SSD 120 gb and 500 GB HARD drive. The HARD disk is a data disc and has been accidentally deleted from the Finder. I can't locate this drive anywhere in the computer.  It is a new drive and was only recently added to the mac.  Desperately need to find.

• Whenever I sync my calendar on Lightning, I get a message "accept changes and update in any case" on several occasions, even though the event is deleted from the server

  This repetition of message every time I sync, therefore can freeze the Thunderbird application after 3-4 syncs

  Right-click recycle the message to the next synchronization
  Left button instantly recycle the message

  Event deleted on the server, lightning and by Organizer

  Disable Google provider problem ceases, but which makes unnecessary lightning

  TBird reinstalled, updated all modules

  Tried to download the image, but no luck...

  I deleted the event to my calendar and was the Organizer to do the same thing.

  What Organizer?

  I have the latest updates from each of the three

  Once again, what are your versions of Thunderbird, Lightning and the provider add-on?

  and charging each of them...

  I mean you don't have to reinstall Thunderbird, then it was a waste of time.

  You can try to remove the calendar in lightning, restart Thunderbird, and then recreate the calendar.
  Given that the calendar is a calendar of network no data will be lost.

  That said, it is always recommended to have a recent backup of profile.

• Why did you move the button Delete in the messages pane?

  You play with my muscle memory! V38.0.1

  Who took me out a few times as well.
  I discovered that if I customize this area of the toolbar and put a space between "delete" and the buttons 'More', in some way I read that space as the end and it kept me acidentally hit 'more' when I went to "Delete".
  I know that this is only a workaround, but it is solved my problem of finger, then perhaps that this idea could help you.

  In the message header area where it shows these buttons: "answer, transfer, Junk, delete archives, more '."
  Right-click on these buttons and select "Customize".
  a 'customize' window will open.
  Drag and drop the icon of 'space' between 'delete' and 'More' buttons.
  (I actually try the dividing line, but found the space worked better for me).
  Click 'Finish' to close the window.

• emails disappear when deleted on the server even though the checkbox 'keep emails from this account on this PC' is checked

  Hello

  I would use my account in such a way that, when an email is deleted from the server (limited space) there is still on my computer.
  It did not work for a while, but since I have a new PC, I was not able to set it up again in this way.
  I use the IMAP protocol.
  Any toughts?

  Thank you very much

  Tamas

  If your mail acted as you claim in the past then it has set up a POP account and not IMAP. POP and IMAP are email standards and work of the same thing all the time. No e-mail client changes which.
  It is possible to have IMAP email account and configure the client as POP with some providers.
  Local folders is a standard account in all installations of Thunderbird.

  I think the problem might be the option "when I delete them. That tells Thunderbird to reach out and the cops messages on the server when you delete them in Thunderbird. Instead, check the box to leave messages on the server and clear the check boxes under that.

• What I have to delete all the emails by hand or I can delete them all at the same time?

  How do delet all the emails at once?

  You can delete several at once. Press the button "Edit" in the mailbox, select e-mail then press on "trash".

  they must be selected one by one, there is no "select all" I remember

  If you have a lot to remove you may wish to do so outside the mail application. If your email provider has a web interface, use it. For example, I have yahoo mail, I use safari to go to yahoo.com and connect to my mail. then I will be able to select many emails at once (or maybe if your email provider supply)

  Can be faster if you have dozens, hundreds of delete
