  I was looking for a way to see who wear's Advisor using his plan, but didn't see a way of knowing on docs, or at least I have not found it.
  Can someone show me that some light on what changes made Advisor to select to reach that way, or how can I watch this that select uses?
  Any help will be appreciate
  Thank you

  The Adviser does not create a new SQL statement - what it has done is create a SQL profile - to accept SQL profile for the task of tuning above:

      execute dbms_sqltune.accept_sql_profile(task_name =>
              'SQL_TUNING_1266335308111', replace => TRUE);
  

  as mentioned in the above report...

  A sql profile applys tips for change (correct) the cost of certain operations - and, to change the execution path chosen by the optiimizer.

• What a time limit for care?

  I waited more than 10 minutes and more for others to make their movements.

  What a time limit for care?

  There are players who walk away a game when they are behind but never

  you know, if you wait for a long time and then must get yourself out.

  A very juvenile manner to act.

  This game is fun when you have a partner of responsible gaming, but lately, there has been a lot of

  Obviously ignorant who play in an abusive manner.

  A reasonable period of time would solve a lot of this.

  If you do not travel in time, your release of the game...

  ROFL. You will need to address this with each different game, you're talking about, by contacting their support, or post in the forums. This isn't a general/portal for games information center.

• Parental control time limit set at 24 hours by mistake... cannot go beyond login.

  Original title: restriction set at 24 hours a time... error cannot go beyond login.

  We have windows Vista Home Basic.  There are 2 user ID in place, it is not used and nobody remember the password.  Another we know the password. However, my son put the limitation on duration of parental control to 24 hours by chance and we can no longer access the computer.  Whenever we tried to enter, we get the message of time restrictions.  Please let me know how we can get around that we can not get the menu system/controls.

  What you wrote is not logical.

  As said by Umesh P, moderator, you need an administrator account to set the time limit.
  And parental controls can be set on an administrator account.
  This means that you must have an admin account, you can log on. If you are the admin or in possession of an admin password.

  For the benefits of others looking for answers, please mark as answer suggestion if it solves your problem.

• The computer did not resync because the time limit was the big change

  Hello

  Initial synchronization problem title: the time in Windows 7 Ultimate edition.
  I have problem with the clock of the computer, I did search but could not find the solution.
  I bought a workstation HP xw8600 outside of the server to lease on Kijiji and installed Windows 7 ultimate.
  My clock is waste of time why I tried following options.
  1. I changed the COMS battery - did not work
  2. I update BIS version - did not work.
  3. I try to implement the interim solution of calendar, a task to synchronize at startup time. by using two commands on
  net start w32time
  w32tm/Resync.
  by doing this, I found that I can't run these commands I need to run these as an administrator, I am able to run these commands in a command window (only if I open the cmd window using the option "Run s administrator". all how create script but and create a shortcut to this script, the value of running as an administrator) When I double click the short cut, it works but do not work in Task Scheduler. After that, I became busy on another work and returned to this question now, the script gives me this error "I don't me the resync computer because the time limit was the big change."
  So there are lost of the question, please advice the best Yes solution of this problem.
  Thank you
      

  Hello

  Method 1:
  You can synchronize the clock of the computer with a time server Internet. This means that your computer's clock is updated to match the clock on the time server, which can help ensure that your computer's clock is accurate. Your clock is usually updated once a week and must be connected to the Internet during synchronization to occur.
  1. open the Date and time by clicking the button of theStart, clicking Control Panel, click clock, language, and region, and then clicking the Date and time.
  2 click ' time tab Internet and then click on change settings. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  3. Select the next toSynchronize box with a time server Internet, select a time server, and then click OK.
  Note
  If your computer is on a domain, you cannot synchronize your clock with a time server Internet.

  
  Method 2:
  I also suggest you to check whether your computer time zone settings have been set based on your current location.
  You can check the link below to adjust the time zone correctly-

  I noticed a lot of databases in my company show using a component called "Automatic SQL Tuning Advisor" or "Automatic maintenance - Setup SQL" in DBA_FEATURE_USAGE_STATISTICS.

  Do we know if this component requires a License Pack Tuning or it could be one of the internal out-of-box/system uses that do not require a license?

• Tuning Advisor error

  Hi all

  Oracle 11.2.0.3

  IBM Aix box

  I ran sql tuning advisor manually by using procedure

  sample procedure:

  () DBMS_SQLTUNE.create_tuning_task

  begin_snap = > 139758,

  end_snap = > 139762,

  sql_id = > "ct4u2889m1458"

  scope = > DBMS_SQLTUNE.scope_comprehensive,

  time_limit = > 60,

  Task_Name = > 'Settings')

  I got the message from PL/SQL procedure successfully completed.

  Then I performed the task of tuning created using the procedure

  EXEC DBMS_SQLTUNE.execute_tuning_task (TaskName = > 'settings');

  Once again received message as PL/SQL procedure successfully completed.

  But when I query using SELECT * FROM dba_advisor_log WHERE task_name = "_tuning";

  I got this output in the respective, INTERRUPTED, ORA-13639 column: the current operation was interrupted because it has expired.

  Any idea or suggestion, why im getting this error, should I get the FINISHED status. I even tried to increase the values of time_limit, but still no go...

  Kind regards

  I increased the parameter time_limit to half an hour. and his filled and got the sql tuning report...

  Thank you

• Tuning Advisor - recommendations

  Dear Experts,
  
  11.2.0.3 RDBMS - I ran Setup SQL for a statement and see the three recommendations:
  
  -Collect statistics for a table
  -Implement the SQL - 99% of shows benefits profile
  -Creating an Index - shows about 78% benefit.
  
  Tuning advisor recommends that a recce to implement. We should I be implemented? Also, with the SQL profile I see 'force match' option, what it means? Appreciate your help...
  
  Thank you

  Hello

  Profile SQL is generally less preferable because
  (1) fixed single query
  (2) it arranges without understanding the nature of the underlying problem, i.e. There is always risk of returning question in one way or another

  On the option 'force game' - it just means that the profile will apply not only to the sql_id you specify, but also all other sql_id which the SQL text differs only in the values of literals. For example if you create a SQL profile for

  select col1 from tab1 where col2 = 'A'
  

  then by default will not affect the plan of

  select col1 from tab1 where col2 = 'B'
  

  but with strength match option, the profile would apply to these two statements.

  About creating index - you need to evaluate the benefits for this and other queries on the cost (slower DML, increased consumption of disk space). How to set up SQL cannot do this for you.

  Best regards

• Is anyway make a composition without the time limit?

  OK, so is anyway make a composition that has no time limit? Oh Yes... and every time I look at the time downstairs bar is coming in 1f - 2f - 3f - 4f... So on, is any way to change this for like 5 s-10 s-15 sec as if it was before? Thank you.

  (CS6)

  You change the length of a composition with composition settings. There is no automatic way to develop a model. If you need to add more time, and then press Ctrl/Cmnd + K or choose Composition > Composition settings and change the time.

  In the timeline panel, you can see more or less of the composition of the adjustment of the display area using the icons at the bottom left of the layer display.

• SQL tuning advisor recommnds to create the function SYS_OP_C2C function index

  I have a large table and an index on it. I use a tool to fill data, this simple tool submits the sql for Oracle DB and it does NOT index to use for requests. When I run the sql tuning advisor, he recommends to create additional indexes and use the SYS_OP_C2C function, which I don't want.
  
  When I run the query through sql plus picks it up in the index.
  Someone of you came, why its recommend that additional nonsense?
  
  create index abc.xxxx on this_table (SYS_OP_C2C ("this_column"));
  
  Thank you

  The internal Oracle SYS_OP_C2C function perform the conversion of a set of characters to another set of characters - C (haracterSet) 2 c (haracterSet). There are situations where you will see this conversion without explicit, as in this case command that should be a sign that the data types are not the same and the implicit conversion takes place and this could also be a problem from the point of view performance because it can disable the use of the index.

  Make sure you the characterset and nls set of all of the database and the tool are the same.
  Make sure that the data type of the column in the index is the same as the database.
  Confirm the ETL vendor for your database support and fixes, etc..

  Optimizer will only advise to use this function when the data type or the character set does not match.

  Thank you

• Package DBMS_ADVISOR can be used for SQL Tuning Advisor?

  Package DBMS_ADVISOR can be used for SQL Tuning Advisor?

  It seems that the DBMS_ADVISOR package is responsible for the workload and SQL Access Advisor of related tasks. Package DBMS_SQLTUNE is responsible for setting up SQL and SQL set related tasks.
