• The SYS user connects to the database level, is this correct?

  My senior colleague gave me following information about the user sys. I want to know, - is this correct?
  
  Since the SYS user connects to the database level, therefore, on the session active user SYS, to kill only the current statement is canceled. The database session does not disconnect. Instead, he continues to run the remaining in the script file instructions where we run a script file that contains a large number of SQL statements.

  If the Oracle session was killed and the customer continued to successfully submit the following commands to the database, a new session was automatically created to replace the killed session. A feature called Of Application Transparent failover which allows the customer to switch to a session of a RAC server to another RAC server, the initial session fails (for example, RAC Server breaks down).

  TAF is part of the response to the so-called "+ the Evil Twins +"-errors and crashes. The rest of the answer are FAN (Fast Application Notification) and CLF (resumption of fast connection). This set of features about the errors and crashes - and allows an application 'seamless' continue even when his Oracle Server session fails.

• Is it possible to set the character set to the instance level?

  Hi all
  
  I have some confusion.
  
  means my database character set AL32UTF8.
  
  and I want tio character set of instance is WE8MSWIN1252
  
  He is liable to set the character set to the instance level?
  
  Please answer Yes or no and why?
  
  
  
  
  Thank you and best regards,

  Instance is memory process structure and background.

  Character set is for the data and the data is stored in the database that differentiate the instance.

  So the answer is no.

• How to set up the database restarts automatically when the server starts?

  Hello
  
  What is involved if I configure Oracle database starts automatically when the server is started/restarted?
  
  I guess that change the following entry in/etc/oratab
  

  DEVDB:/u01/app/oracle/product/10.2.0/db_1:N

  TO

  DEVDB:/u01/app/oracle/product/10.2.0/db_1:Y

  is not sufficient - there is more than that. But what is it?
  
  We can also configure the listener to automatically re / start?
  
  I guess that everything what is the solution, it will also apply to Oracle 11 GR 2 databases/ASM - right?
  
  The platform is Redhat Linux 64 bit (version 4.7 & v5.9).
  
  Thanks in advance!

• How to find AUTO_SAMPLE_SIZE set at the DB level?

  Version: 11.2.0.4

  OS: RHEL 6.4

  We use below collect stats procedure for gathering statistics for our tables.

  exec dbms_stats.gather_table_stats (-)

  ownname = > 'QMP, -.

  tabname = > 'HRTB_MASTER ', -.

  estimate_percent = > DBMS_STATS. AUTO_SAMPLE_SIZE, -.

  Cascade = > TRUE;

  method_opt = > 'for all THE COLUMNS of SIZE AUTO '.

  );

  We use a custom procedure that runs dbms_stats.gather_table_stats for the selected tables.

  Lately that gather employment stats took longer. When we checked DBA_TABLES. SAMPLE_SIZE these tables, we noticed that it is 100%. That is to say Oracle is 100% sampling.

  We thought that DBMS_STATS. AUTO_SAMPLE_SIZE was 10%, by default. How can I determine DBMS_STATS. AUTO_SAMPLE_SIZE currently set at the level of the DB? Google search did not help

  It's a shame the manuals do not tell you anything on the algorithm and particularly the effect of the global preference APPROXIMATE_NDV setting to true.

  Check the result of:

  Select dbms_stats.get_prefs ('approximate_ndv') of double;

  If the result is "true" then you have activated the mechanism of approximate_ndv for the collection of statistics on the table and Oracle will use 100% the size of the sample of auto. The advantage of this is that is don't do massive unique on each column to get the num_distinct, and it will get the correct answer to about 1.5% in time to make a small percentage using the older mechanism. If this is the case in your system, as has been pointed out by Stefan, the extra time can result from several work to calculate a number accumulated histograms; It can also disappear for large sample sizes used for indexes more.  NOTE: even with auto to 100% on the table with approximate_ndv, histograms, and index, always use the same sample old 'auto '.

  Here is a link that will take you to a whitepaper on the subject if you are interested: https://jonathanlewis.wordpress.com/2009/03/20/hotsos-2009/

  There are some side effects, however, which could have a significant impact on a few unfortunate, for example: https://jonathanlewis.wordpress.com/2014/03/02/auto-sample-size/

• Changing the character set in the database 11G

  Running Windows 2008 Server 64-bit and Oracle 11 g (V 11.2.0.1.0). I would like to change my default character set when installing from 11 G to CS AL32UTF8.
  
  I read the utility Guide and Guide Support for globalization (http://docs.oracle.com/cd/B28359_01/server.111/b28298/ch11charsetmig.htm#g1011430), but none of these documents shows how you can effectively change everything / the character set of the migration. I would do this using the export and import utilities since this seems to be the most popular recommendation. But I'm really not sure of the procedure to follow to change the CS. For example, should I first export and then import then run the CSCHANGE script that is described in the globalization support Guide?
  
  I would be grateful any guidance on how to actually change the character set to AL32UTF8 and all documentation that explains not only the concepts, but the STEPS of HOW this can be done. Thank you, J

• Number of elements must be set to the logical level

  In the channel Business model, mapping, dimension > logic > > number of items at this logical level
  
  I came across two different versions of how to treat this
  
  First version - the OBE and the server admin guide, it says "the number does.
  no need to be exact, but the numbers of one logic level to the other, rates should be accurate."
  
  Second Version - a question asked about what defines the number level both as best practices
  
  To set the number of items at each level of a dimension, what number would you use?
  
  A. the number of columns in a logical table
  B. the number of levels in a dimension
  C. the number of dimensions in a business model
  D. the number of tables in a physical model
  E. the number of separate lines in the physical column
  
  It comes
  What is the rule to set the number of items at this level?
  
  If its been settled according to the rows in the table. What happens if the lines gets added every hour?

  The relationship between the levels, which is important according to me. BI Server will use this information to determine which source of aggregation to use. You must use the number of separate lines as the value.

  You can also right-click on the hieracny and "Levels of estimate" allows you to automatically fill in the numbers for you.

• Have lost the ability to change the level of difficulty on the games of Freecell. It was there originally, but is now set to the hardest level? can anyone help please?

  Until recently, I was able to choose several levels of difficulty for Freecell card game using the 'Options '. Now there is no choice available under 'Option' or any other position. The game is stuck at the highest level with all combinations of 4. How can I get games with least difficulty IE 1 or 2 costumes? Please can someone help?

  Hello

  1. Since when are you facing this problem?

  2. are you aware of the changes made to the computer before the show?

  Method 1: Try to turn off the game by going to enable or disable the functionality of Windows and later the tower and check if that helps. Follow the link given below for the same thing.

  Enable or disable Windows features:

• BlackBerry leap speaker crackling and caller voice level is so low even set at the highest level.

  New 1 day old phone and the speaker is crackling during the speakerphone mode or when you adjust the volume level of notification. In addition the audio level of voice calls is barely audible. It's exactly like my old Z10. Come on blackberry? !!! You guys are really all QA before packinging your products or is - this new Bond is a repackaging of exccess and components of the Z10?

• to access the QML attached objects in C++ and best practices for the handling of the user interface in classes

  Hello

  I have in fact 2 queries

  (1) how can we access attachedobjects defined in QML in C++?

  (2) I'm loving development on Blackberry 10 C++ is one of my favorites. But I'm a bit lost when it comes to managing the user interface in classes. For example when we create the project through momentics we have a class called ApplicationUI. It manages all the (default) user interface commands, we in C++. as for example creating the document qml and setting as root user interface, etc. I am now working on an app that have NavigationPane as root, and then I continue to push pages (like the screens). But now the code for all pages is inside my ApplicationUI. What is the best practice to keep the UI for each page logic in a separte C++ class?

  I also develop for Android that a separate class for each activity, this code does not mingle for each activity. Please guide me how can I keep logic of user interface of each Page into a separate class of C++?

  regarding your second question:
  I think this is the simplest approach to keep all things in the UI in QML. You can easily put things into separate files.

  If you want to use c ++ to the user interface: can be done, too. just put it in separate classes and include those in your application class.

• view set or the aggregate function

• How to set up the database

• Even though I have my Windows Mail spam set to the highest level, I continue to receive unwanted emails. For some reason any Windows Mail does not block them. How can I fix it?

  I have my blocker spam Windows Mail, the highest value which means I should only receive emails from my contacts.  Despite this, I continue to receive unwanted emails.  This has been so since I've upgraded to Windows 7.  I even went now install a machine program washing 'spam' which was a disaster as well.  I get about 4-5 spam emails a day - usually when I start the morning.

  How can I solve this problem?

  What Windows Mail in Vista or Windows Live Mail in Win7? If it is a POP3 account, you can filter your messages by using message rules. This is for Outlook Express, but it works the same either of the programs.

  Start with the only rule of AddressBook and you receive a message that you want people not in your address book (E-mail from companies, bills, your ISP, etc), you can add them to the rule.

  Box 1 - Where the From line contains people {check it out}

  Box 2 - Check: delete it & stop processing more rules if you want messages not in the address book to go to deleted items, or you can create a spam folder and direct them here.

  You can choose to delete the server, but be careful because you never have messages downloaded to any folder, if you choose this option.

  Box 3 - Click on the blue words contains people

  Click on the first address to select it. Scroll to the end and hold down the SHIFT key while you click the last address. This will highlight all. Right-click on it and click on from the menu that appears.

  Now, click Options and choose: Message * contains no of * the people below in the top of the page Options area, then choose: Message corresponds to one of the people below in the background Options box.

  OK your way out of the new rule.

  Now, only the addresses that you entered will be uploaded to your Inbox. You won't see other emails.

  Remember, if you add a person to your address book, you must add to the rule. It will not automatically be added.

  Be sure to see these links for more options.
