• Simple question about Append hint

  ORACLE-BASE - title

  The link above, I have just a basic question about add suspicion...

  How the APPEND Hint affects the performance

  The APPEND tip tells the optimizer to perform an access direct-path insert, which improves the performance of INSERT .. SELECT operations for several reasons:

  • Data are added at the end of the table, instead try to use the free space in the table.
  • Data is written directly to the data files, passing the buffer cache.
  • Referential integrity constraints are ignored.

  I wanted to just understand to what extent is the third correct point

  -----------------

  CREATE TABLE emp
  (
  emp_id a PRIMARY KEY/NUMBER
  emp_name VARCHAR2 (100),
  dept_id NUMBER
  );

  CREATE TABLE dept
  (
  dept_id NUMBER PRIMARY KEY,
  dept_name VARCHAR2 (100)
  );

  ALTER TABLE ADD FOREIGN KEY (Dept_id) emp made REFERENCE to Department (Dept_id);

  
  INSERT / * + append * /.
  IN emp
  Select 1, 'King', 100 from dual;
  
  COMMIT;

  The insert will definitely give an error

  ORA-02291: integrity constraint (SCOTT. SYS_C0013725324) violated - parent not found key

  Am I missing something here?

  See you soon,.

  Manik.

  sqlldr can and does ignore referential integrity / triggers and same uniqueness in a load path direct, insert / * + append * / doesn't - you do not direct path when they (constraints) exist. parallel is always a direct route, if you go in parallel, you add.

• Question about ordering "suspend."

  About VMware Server 1.0.4 running on Ubuntu, if I do, "vmware-cmd suspend http://path to the .vmx file" , he responds with, "suspend() = 1". This answer means that the virtual machine is completely suspended? Or does this mean that the order has been sent successfully, and that the virtual machine is now in the process of suspension? If it's the latter, is it possible to check for some that the virtual machine is indeed completely suspended?

  Thank you!

  suspend() = 1 means, that the machine has been properly suspended.

  Be very careful with suspension. Prefer the following:

  VMware-cmd /path/to/my/vm.vmx soft stop

  For this the correct stopping down to a VM. Prerequisites: VMWare Tools installed on the client.

• Question about orders in single-user mode

  Hi all, I am a super novice of mac system.

  I searched the web and the apple community, and I have not found much information on how to use the single user mode.

  All suggested link to read and learn about the single-user mode and terminal?

  What you trying to accomplish?

  Single user mode is a shell capable of functioning when things on the hardware have problems.

  It is not a fully functional shell, it is intended for solving problems.

  Terminal on the other hand maybe you want to explore. There are many ex http://blog.teamtreehouse.com/introduction-to-the-mac-os-x-command-line resources

• Question about parallel hint and 'alter table enable parallel DML'

  Hi all
  
  I have a DML as follows:
  
  Insert / * + append * / into table1
  Select *.
  of COMPLEX_VIEW;
  
  Here complex_view contains a very complicated SQL, in which there is some heavy tables joins, subqueries, and aggregations.
  
  Question 1:
  
  Let's assume that the underlying tables have no attribute "parallel." Where should I add "parallel index" to force it to be run in parallel and can get better performance?
  
  Some members think that what follows is good.
  
  Insert / * + append * / into table1
  Select / * + parallel (a 4) * / *.
  of COMPLEX_VIEW;
  
  But I think that indicators must be put in the defintion of the complex view where they should be and do not put advice to the main insert DML, like this:
  
  Insert / * + append * / into table1
  Select *.
  of COMPLEX_VIEW; -I added the indicators in the COMPLEX_VIEW.
  
  What is your opinion?
  
  Quesion2:
  Without ' alter session enable parallel DML ", I can see the parallel session in v$ px_session thus." And the execution time has been shortened. This proves without this statement, the DML is also run in parallel.
  
  So, what is the effect of this statement?
  
  Best regards
  Leon

  I prefer the suspicion out of the COMPLEX_VIEW. This way, only this application forces the suspicion. If you put the indicator in the COMPLEX_VIEW, any other query on COMPLEX_VIEW (or Assembly of COMPLEX_VIEW to another view or a table) would also "encode" indicator in its execution. You don't then isolation parallel query to only where it is needed.

  If you put the parallel indicator in SELECT it (or view), the query is parallelized. This does not necessarily mean that the INSERT is parallelized. What you see v$ px_session are only slaves to PQ to SELECT.
  You must ALTER SESSION ACTIVATE PARALLEL DML and add the PARALLEL indicator in the INSERT.

• question about orders of vista: using the mouse

  could someone means give me the list of commands in vista which has to do with the mouse?

  Tips of mouse [Prev | ] Next | Content]

  Click with the right button on the title bar	Recommended Windows menu mode (formerly the system menu or control)
  Double-click the title bar	Activates / deactivates a window between the Normal State and Maximised.
  Right click on the System Menu or folder in Web view icon	Open the context menu for the container. Vista: feature removed for windows explore. Interface user Vista guidelines, however, recommend that the icon is a document icon in applications of document type and show the context menu for the document on right click. Document not applications, such as MS Messenger, should show the application icon and context menu should apply. Left-click on the icon should display the Windows menu for compatibility reasons, but it should not be documented, do a right-click with the exception of the title bar icon is the new documented way.
  Drag an object on a Windows title bar	Opens the object in this window (do slide in the window will often work, but in OLE documents this will insert the object in the active document). Some programs, such as Notepad insist on the files being deleted in the client area.
  To drag an object, then place the cursor over a folder collapsed in Explorer tree	Expands the view of folder
  Drag an object on the border of the client area of a window	Scrolls the window. The client area is the part of a window that contains the objects or documents. It does not include the title, menu bar or toolbars.
  To drag an object, then mouse over a button of the taskbar	Brings the window associated with the button on the taskbar to the top
  To drag an object, then place the cursor on an empty part of the taskbar.	Minimize all open windows
  Double-click the bar of relief on the left side of the toolbar in the taskbar while the taskbar is unlocked	Activates / deactivates the toolbar through maximum size, minimum size and content adjustment

• Question about orders and the inputs of the element of the API

  Hello
  
  Pay_element_entry_api allows us to update the values of the clip. Similarly, we have pay_batch_element_entry_api through which we create master batch and lot lines and update the entries in the element. Can someone explain what is the difference between these 2 types of methods?
  
  Thank you
  
  KK

  The second method gives you more control: the user can decide when to download the Scriptures, chenge their values, validate before the transfer, handle exceptions and so on.

  One requires less work: the entries are created immediately without user intervention.

  It depends on the business process.

• question about PARALLEL hint

  the documentation says that this PARALLEL suspicion may by select statements used in as PARALLEL (emp 8). I've also seen some syntaxes like PARALLEL, PARALLEL 8, PARALLEL (8) and in each case the steps in execution plans are the same, but the assigned cost was a little different between each version (but much lower than for a query without this suspicion).
  
  How he interprets oracle above three syntaxes, IE.

  /*+ PARALLEL */, /*+ PARALLEL 8 */, /*+ PARALLEL(8) */

  ?
  are there parts in these syntaxes that are ignored or integrate the default behavior?
  which syntax is safe to use when you don't want to specify the table being parallelized, IE. Use a similar syntax PARALLEL (emp 8)?
  
  Thank you

• A question about the order of COLUMN sqlplus and PL/SQL

  Hello everyone.
  
  
  
  I would like to ask a question about sqlplus command COLUMN that I use in order to define the length of my queries of output columns. So, for example, I run something like:
  

  COLUMN market FORMAT a20

  That is why any column with the name 'the market' will be composed by sqlplus as 20 characters.
  
  Currently I'm working on a PL/SQL script that makes this automatic procedure, in other words, instead of manually write for each column in the above COLUMN order, it uses the DBMS_SQL. He read first as input the name of the table and then inside a loop, it detects the maximum length.
  
  For those interested, here is the Oracle documentation page that I found (example 8)
  http://download.Oracle.com/docs/CD/B19306_01/AppDev.102/b14258/d_sql.htm
  
  If everything worked well enough I managed to recover the maximum of each column in my table length, except that I don't know how to use the COLUMN sqlplus command in my PL/SQL block. I would like to do something like that (it's just a pseudo-code)
  

  FOR colIndex in 1 .. numberOfColumns LOOP
          currentColumnName = getColumnName(tableDescriptionObject, colIndex);
          currentColumnLength = getColumnLength(tableDescriptionObject, colIndex);
          
          COLUMN  currentColumnName FORMAT a -- and here after 'FORMAT a' I have to write currentColumnLenth but I don't know how to proceed.
  
  END LOOP;

  I would like to know is there a command in PL/SQL to define the appropriate column typeset in sqlplus length?
  
  
  Thanks in advance,
  Dariyoosh

  Hi, Dariyoosh,

  Sory, I don't think that there is a simple way to publish SQL * most orders fom PL/SQL.
  PL/SQL runs in the database (back-end); There isn't any direct contact with SQL * more at the front end.

  The best way I know is that PL/SQL script (myfile.sql) with orders of the COLUMN, and then have SQL * more run the script (@myfile).

• Many questions about the HP 50 g

  I just ordered a HP 50 g graphic calculator! I have a few questions about this so hang on tight! What is the USB connector on the calculator? Mini-USB, micro USB, or is it a connector owner, "custom". Then, it would be possible to connect a keyboard to the HP 50 g by using the USB Port? Is there a program that would make this possible? (I doubt it would work if you plug it..) I have a Mini-USB to female USB 2.0 connector. So I could just plug the keyboard right, provided that the port on the calculator is a Mini-USB Port. If this is not so that I could use my female to female USB adaptor to connect the keyboard.

  Thanks for your help,

• A few quick questions about the Satellite P300 - 18 M

  Hello

  I am about to order a Satellite P300 - 18 M and have just a few questions about this:

  (Although these may apply for other similar Satellite/Equium P300.)

  Is the touchpad made by / to use the Alps or Synaptics driver?

  It has the Wireless N network card, is the map made by Intel or Realtec?

  And also, someone has experience with face recognition software to connect?

  If so, does it take a lot of time to initalise?

  Thanks in advance,
  Jack

  Hello

  The P300 - 18M belongs to the PSPCCE series.
  It uses the two touchpad drivers. Synaptics & Alps Electric
  There is an Intel 802.11agn minicards WLan installed

  The face recognition is a nice tool but local to be illuminated and you must take your face the right of the post sometimes it of not very easy

  But if you face is recognized correctly that the connection should work properly

• Question about temperature internal Satellite A300 ND1

  Hello

  I have a question about the temperature of the standards it of ok for my laptop and what is the normal temperature and how can I keep it low?

  Thank you.

  Hello

  It's not easy to say what a normal temperature could be.
  The temperature is not always the same and it depends on the use of the laptop.
  Usually, the temperature would increase while gaming or running applications high performance. Why? Because all devices such as the CPU and GPU would focus the heat dissipation and this leads to a higher temperature.

  > How can I keep it low
  Very simply, you can keep still low level, but you can make sure there is enough free space around the laptop to ensure good air circulation.
  Also don t use the laptop on your knees etc in order do not obstruct cooling fans.

  It s also advised to clean the fans from time to time using the jet of compressed air. These sprays are really useful and could buy in the stores of different computers.

• A few questions about the recovery image installation

  A recovery USB drive created using the Recovery Media Creator contains the Windows operating system and is it the Windows key to reinstall - how it is activated. Is it different for the repair disk.

  Can be used for a new installation of Windows 7 on a new SSD? Is this just a case of connection and the recovery disc running on the new drive to th? How the recovery Partition can be re-created on a new SSD?

  Drop Hello

  I can see user Justinian gave detailed answers, and I hope you understand how it all works now. Of my overwiev aside:

  What exactly is recovery image?
  + Recovery image is an exact copy of a hard drive and contains the exact copy, byte by byte, a hard disk partition. The copy includes all the partition information, sectors priming, the table of allocation of files, installation of operating system and software application different. +
  + You are using installation Recovery CD/DVD/USB, you can restore your system after heavy data loss, caused by an accident of operating system, hardware failure or complete virus attack. +
  + Recovery image installation procedure allows the installation of system and easy to user. Unfortunately, it is not possible to restore only certain files from a disk image. +
  + Each recovery image is designed for a specific model laptop and it cannot be used for any other series of notebook. +

  With other words, recovery image is a software package that contains Windows operating system, all the drivers needed for some portable model, Toshiba tools, utilities, and also some other software. A lot of people don't like these additional software, but no you don't have to use it. all things you don't like you can remove it from the system.

  Activation of recovery image:
  When you buy the phone model you also purchase the license for the preinstalled OS version that you get with your machine. After start and contact to the internet OS will be checked and activation will be valid.

  Please note: you can reinstall original image recovery 100 times if necessary. There is not a kind of limitation, and whenever it will be activated.

  Take care of your recovery media (DVD/USB). Do not lose it.

  Of course, it can happen that you do not find your recovery media. In this case you can order.
