• I use the same query in two difference db (exp/imp) but run different times!

  Hello
  
  I have 2 database. One of the remote server, one at my local. I used exp/imp to retrieve data from remote to my local database. Structers, tables and indexes is the same.
  My local machine is more powerful than the remote computer. (Ram, cpu County ext)
  
  But when I connect remotely from my local computer, this application runs 4 second (with view). But when I connect to my local db, this query run 5 minutes.
  Number of rows returned is 18,500
  
  What's wrong? Why get the bytes of the value are different?
  
  Local explain plan is:

  SELECT STATEMENT ALL_ROWS Cost: 203 Bytes: 19,062,160 Cardinality: 18,329                                         

  Remote control explain plan is:

  SELECT STATEMENT ALL_ROWS Cost: 226 Bytes: 3,855,214 Cardinality: 18,446                                         

  My plans to explain (remote and the) and other (auto track, oracle params) data is in excel file (because of this forum not to accept more than 30,000 words);

  Thanks, Johan, I'll try.
  My first post for local oracle param, I got it 3 days ago. or I confuse my file params to oracle. (This problem continues from last week)
  Now I'm waiting still current oracle local params and these value is worse:

  Local:
  pga_aggregate_target 0
  SGA_MAX_SIZE 536.870.912
  SGA_TARGET 0

  I update the new oracle local params in my previous message.

  I'll try the update of these values, but I hope, my local oracle is not drop down :)

  Can't be worse...
  You have a parameter memory_target (and max_memory_target)? If so, you could add memory to these settings as well and only set pga_aggregate_target (no CMS or sga_max)

  My settings (on a test/dev/lab-box):
  System@oracle11 SQL > see the memory settings

  VALUE OF TYPE NAME
  ------------------------------------ ----------- ------------------------------
  hi_shared_memory_address integer 0
  whole big memory_max_target 3G
  whole large memory_target 3G
  shared_memory_address integer 0
  System@oracle11 SQL > show parameter sga

  VALUE OF TYPE NAME
  ------------------------------------ ----------- ------------------------------
  lock_sga boolean FALSE
  PRE_PAGE_SGA boolean FALSE
  SGA_MAX_SIZE large integer 0
  SGA_TARGET large integer 0
  System@oracle11 SQL > show parameter pga

  VALUE OF TYPE NAME
  ------------------------------------ ----------- ------------------------------
  pga_aggregate_target large integer 0

  This way I pushed things like Oracle by itself, memory allocation to everywhere where oracle needs him the most.

• Using the same application with filters prompted by guided Navigation

  Hi gurus,
  
  
  I have a requirement in which I need to show a report only when it returns results.
  
  To do this, I put the request in a section and applied a guided navigation using the same request as a source of demand.
  
  Can I use the same query in the navigation guided as request to the source?
  
  In the application there are filters which are invited
  
  My question - > in demand of guided Navigation Source, what I have to do the filters that you are prompted, or what I need to make it equal to the variables of presentation, which are populated by dashboard guests.
  
  I also have one of the guest as a guest of multiple selection...
  
  
  Thank you
  Ashish

  Ashish,

  Yes, you can use the same request here.

  For the application, you can use "IsPrompted" if same column is used in the guest of another use variable presentation here which is populated from the dash prompt. Just, 'specific' selected value based shud report results.

  Hello

  LEVEL is not a real column - it's a nickname, so it shouldn't be on your table, because it generates the SQL.

  Your statement could be something like:

  SELECT LPAD(' ', 2 * (LEVEL-1), '.') || "NAME" d, "PAGE_NO" r
  FROM APEX_PAGES
  WHERE PAGE_NO NOT IN (SELECT "PAGE_NO" FROM "#OWNER#"."APEX_USER_PAGES" WHERE "APP_USER" = :APP_USER)
  START WITH PAGE_NO = 1
  CONNECT BY PRIOR PAGE_NO = PARENT_PAGE_NO
  

  I don't know what would be your starting page number - it would be to the top of the tree - so I just put 1 in this example.

  Here is a page that I put in place using my example of EMP table, just to show what would be the result: [http://apex.oracle.com/pls/otn/f?p=35917:22]

• Determine the maximum length of a column and its use in the same query?

  I would like to determine the maximum length of a column and use it in the same query. Is this possible? IE:
  
  SELECT RPAD (last_name, SELECT MAX (LENGTH (last_name)) + 5 FROM user, '-')
  OF the user.
  
  Thank you

  Thank you

  Sure. You almost go in your message: a scalar subquery . Just put brackets around the subquery:

  SELECT      RPAD ( last_name
            , (
               SELECT  MAX (LENGTH (last_name)) + 5
               FROM    user_tbl          -- USER is not a good table name
              )
            , '-'
            )          AS padded_last_name
  FROM      user_tbl
  ;
  

  Scalar subqueries in SQL are like tape in your garage in canvas: they are used for thousands of different things and open, maybe 1% of them. Usually, there are better ways to achieve the same results, such as the analytical functions:

  SELECT      RPAD ( last_name
            , 5 + MAX (LENGTH (last_name)) OVER ()
            , '-'
            )          AS padded_last_name
  FROM      user_tbl
  ;
  

  Still another way is to make the subquery and then join his game as if it were a table of results:

  WITH     got_max_length     AS
  (
       SELECT     MAX (LENGTH (last_name))     AS max_length
       FROM     user_tbl
  )
  SELECT      RPAD ( u.last_name
            , m.max_length + 5
            , '-'
            )          AS padded_last_name
  FROM           user_tbl     u
  CROSS JOIN     got_max_length     m
  ;

• Uses the same drivers as Windows 7 Windows 8?

  Hello! I was wondering if Windows 8 uses the same base drivers under Windows 7. I considered dual-boot on my old Windows 7 computer that had defective drivers, to avoid the risk of my newer computer. Would I be able to dual boot and have different drivers, or Windows 8 uses the same drivers on Windows 7? On a side note, it would even work, or have I missed some crucial detail?

  Windows 8 and Windows 7 share the same driver model. Windows 8 comes with a standard set of class for the peripheral communes drivers. Usually, drivers that are preloaded with the OS offer basic functionality and you must go to the website of manufacturers of device for drivers optimized for the device, this includes devices such as your video card or a printer.

  According to the edition that you run, you can keep your personal files, applications, and settings. Apart from that, I recommend strongly dual boot with your existing operating system rather than replace it with the output preview Windows 8. Preview release is still in heavy development and do not replace a copy of production Windows with it (be it XP, Vista or Windows 7).

• Why I have two different execution plans for the same query on two different servers

  Hello everyone.

  I need your help to solve the problem quickly.

  In a nutshell, we have two servers that have the same version of Oracle RDBMS (11.2.0.4 EE). One of them for purposes of development and another is a production one.

  We have therefore two different execution plans for the same query executed on both servers. The only case of execution is OK and another is too slow.

  So I have to slow down the work of query using the same scheme to explain that young.

• Use the same image twice column in a report

  Hello

  I have a question which is, I can use the same column (column A in the example) picture twice in a report? first occurrence (column A) will show the thumbnail of the image and the second occurrence (column A) will display the image download link that opens the picture in a new window. Is this possible?

  Thank you

  Yes, it is possible. However, if you intend to have two different images, then I would suggest you use javascript to link or download the blob.

  What's happening on Earth? Why JavaScript is necessary to download two different images? Even if he was in any real way, the OP is clear that the link posted of thumbnails and download involves the same image.

  To accomplish this task, you use decode or create a union query.

  No, all that should be necessary is the image column twice in the projection of the reference report query and apply a mask download format to a column and one mask of the image to the other. That the OP apparently did not this probably indicates that they are unnecessarily complicate things.

  For example:

  Select '' link_col

  table

  where allow_view = 'Y '.

  Union of all the

  Select '' link_col

  table

  where allow_view = ' don't

  or

  Select decode (allow_view, 'Y',

  '',

  ("") link_col

  table

  What is downloadImg? It is not a Standard API JavaScript APEX. Therefore, it is highly unlikely that this is of no use to the op.

• How to separate 2 IPADs using the same Apple ID

  Problem: I have 2 iPad (IPAD 2/IPAD Air) using the same Apple ID.  To maximize the storage capacity on two IPADs, how can we separate the two so that each IPAD will show its max 16 GB storage?   I have to reconfigure the old IPAD back to factory setting?  I create an AppleID separated for the IPAD 2?  Your comments are greatly appreciated

  I'm not sure I understand what you're talking about. If you have two 16 GB iPads, they have only about 13 GB of storage available out of the box. Using the same Apple ID on both devices does not affect the amount of space you are using, if you sync the same content for both and in everything you turned on automatic downloads and use iCloud photo library on both devices.
