  I have a question about the index. Is - this required that the index will be useful if we have a "WHERE" clause I tried to find myself there but do not.
  In this example I haven't used where clause used but group. But it gives a comprehensive analysis. Is it possible to get the scan interval or something else using Group by?

  Since I was on what they do full scan. Is it possible to restrict of fullscan without using where clause?
  I guess having limit clause but not quite know.

  Why?
  If this query is producing good results, then you need a full analysis.
  If fool you somehow the optimizer by doing a scan of interval, it will be slower.

• I have a doubt about the file .folio and publications

  Hello, I m new here.

  I want to start working with DPS, but I have a doubt about which version to buy.

  At the moment I have one customer just wants to publish a magazine, but my intention is to have more customers and publish more magazines.

  If I buy the unique edition of DPS, I read that I can publish a single file .folio. What it means? Each folio file represents a publication?

  Please, I need help to understand this before you purchase the software.

  Thank you very much

  Here's a quick blog I wrote to compare the simple edition and

• Some doubts about the topology, interfaces and security modules

  Hello
  
  Below, some questions about the ODI:
  
  
  1. to use an LKM ODI always ask to use two different DATASERVERS (one for the SOURCE) and another to the TARGET?
  
  2. what would be the best way to create a new IKM with GROUP BY clauses?
  
  3. What is the required minimum PROFILE for developers users could import projects created in other ODI environments?
  
  4. If a particular WORK_REP is lost, it is possible that retrieve projects from version control information stored in the MASTER_REP?

  1.) Yes. LKM always loads data from one root to another.
  More than once I saw that even if there is a single physical server, several servers are configured in the topology Manager. This would lead to the use of a LKM because ODI consider 2 different servers.
  If the physical server is set only once, LKM won't be necessary.

  2.) IKM automatically adds a GROUP BY clause if it detects an aggregation function in the Interface implementation.

  3.) try to use the profile of the creator of NG.

  4.) this is not an easy task. But all the versioned objects are compressed and stored in a BLOB field in the master repository.
  You will need to know the names and versions you need to recover.
  SNP_VERSION and SNP_DATA have this information. Retrieves the field BLOB SNP_DATA and unpack using a zip utility. This will give you the XML property of the object that was transferred.
  Now, you can import this xml file and retrieve the object.

  You will need to loop through all the records in order of I_DATA, then extract to .xml file, and then import them to build the work rep.

• doubt about the update

  Hi all
  
  Three statements to update, I need to run on a single table.
  Is there a way I can update instructions executed all three in a single statement?

  Hello

  You can combine the statements by combining subqueries.
  No logic not apply to all the the original updates must be out of the WHERE clause and put in a CASE statement.
  The CASE statements should "update" column to itself if none of the conditions apply.

  For example, your final two statements UPDATE, that have subqueries on s_postn, both can be combined like this:

  UPDATE     xxops_forecast_extract     b
  SET     position_id =
       (
       SELECT     CASE
                 WHEN     (     b.am_id          IS NOT NULL
                      AND     UPPER (a.name)     = 'TD-' || UPPER (b.am_id)
                      )
                 OR     (     b.am_id          IS NULL
                      AND     UPPER (a.desc_text)     = UPPER (TRIM (b.position_name))
                      )
                 THEN     a.row_id
                 ELSE     b.position_id
            END
       FROM     s_postn     a
          WHERE     UPPER (a.name)          = 'TD-' || UPPER (b.am_id)
       OR     UPPER (a.desc_text)     = UPPER (TRIM (b.position_name))
       )
  ;
  

  There seems to be some mistakes in the statemnts UPDATE that you posted. For example, the last two refer to a column called position_level that does not exist in the other table.
  The above statement produces the results you want with the data you've posted.

  As you can see, the code is much harder to understand, debug and maintain.
  If the performance gain (if any) justifies the addional complexity is debatable in this case.
  I'm sure that combining all three queries would be useful.

  Consider using the MERGE: it is sometimes easier to use, even if, as in this case, you're never insert.

• Doubt about the Performance

  Dear all,
  I'm running a procedure, and it should update the 8 million records.
  It uses a packaged procedure which is going on in another data base using the link of database to get certain values based on certain parameters.
  If the procedure doesn't return any data (in THE settings) then it must be inserted into a table of newspaper.
  If the procedure returns some data then it must be applied to the record in the database, like that it must update all records of 8 million
  
  But my procedure takes more than 14 hours to run.
  
  The following procedure is that I'm getting.
  It seems very simple, but I really don't understand why she's taking a lot of time.
  
  Guess aside.
  1 > to fill the lack of recording in the JOURNAL Table I use a PRAGMA AUTONOUMOUS_TRANSACTION procedure in the procedure itself and commit the data to see the results of the PAPER while still it runs the procedure. This will cause this procedure got COMMIT inside.
  
  2 > or it's because we use an external DB which is present in another data base package.
  
  The procedure seems very simple, but I don't know why it takes a long time.
  
  Appreciate any feed back.

  Sins:

  Looks like you need to rethink this approach and use SQL directly instead.

  or any other good metod?
  
  
  There may be affected lines from 1 to 10.

  Hello

  INSERT INTO SELECT will be best option if your data are not very large. It is benefecial as you would use SQL and PL/SQL, which will ensure that there is no context switching.

  If the data in the table are very large, then batch insert by using the cursor and bulk insert and then commit is advisable.

• Doubts about the line of the error

  Hello
  
  I have the following schema:
  
  A publication, "P_REA", which has 15 points of publication.
  And 15 steps associated with this publication.
  
  Another publication, "P_REA_2010", which has 17 publishing points.
  And 17 sequences associated with this publication.
  
  Each publication element, P_REA, points to the same table as P_REA_2010.
  Example:
  
  X: part of publication in P_REA
  Y: element of publication in P_REA_2010
  T: table
  
  X and puts at the same table "T".
  
  A customer who had associated with P_REA, is associated with P_REA_2010 without uninstalling with WebToGo.
  
  By synchronizing this client appears in the queue of the error without any warning and duplicates of publishing points.
  Example:
  
  X (part of publication in) P_REA 0
  Y (part of publication in) P_REA_2010 0
  
  
  Is someone can tell me this error?
  
  Thank you very much.

  What is the error which is fiven in the queue of the error and how. Table c$ EQ is the error queue header and the first point of failure for a transaction will be the details of the problem in the message.

  When you configure the second request, is
  (a) designed as a replacement for the old man, that is to say: the user will be transferred from P_REA to P_REA_2010
  (b) are completely separate to know: each application uses the same objects, but has elements of different publication their SEO
  (c) two separate requests/publications, but using the same elements of effective publication
  (d) to make two sets of sequences have different names, and you have the starting points, so they could not overlap

  Oracle has normally say that you can't have the same objects in several applications, but it tends to work well if they are published separately (but be careful with the changes that the effect on their triggers and tables of the CEQ/CVR/CLG will happen on a change for each application).

  If you share the publication to fast refresh items you could get some issues such as the data of the COP/MOP$ tables set up in the MGP deal and used as the key for download can be inconsistent that two applications will try and set it and download it.

  If you switch users from one application to another, then remove a user of an application does not automatically deletes the customer odb file, and several application odb files can be there at the same time

• A question about the count of several lines of table in a PL/SQL block

  Hi all
  
  
  
  
  I have a problem on counting the rows from several tables in a PL/SQL block, and I would be grateful if you could kindly give me a helping hand. Here's my problem: file in Microsoft Excel (one column) I have a list of several names of tables. For each table, when the number of rows is equal to 10000 I have to call a procedure. Here's how I tried to do:
  

  DECLARE
       CURSOR tb_cursor IS
            WITH my_table_names AS
                 (
                      SELECT  'table1'  AS tbname  FROM  DUAL  UNION
                      SELECT  'table2'  AS tbname  FROM  DUAL  UNION
                      SELECT  'table3'  AS tbname  FROM  DUAL  UNION
                      SELECT  'table4'  AS tbname  FROM  DUAL  UNION
                      .
                      .  Here I continue writing one line for each table in order
                      .  to have the table names stored in my Excel file as a table 
                         to be queried by SELECT statement
                      .
                 )
            SELECT *
            FROM my_table_names;
  BEGIN
       -- Here I verify that for each table having more than 10000 lines
       -- I call the specified procedure which is needed
       
       FOR I IN tb_cursor LOOP
            DECLARE
                 -- Here I declare a cursor for counting the number of rows
                 CURSOR currentTableRowCounter IS
                      SELECT COUNT(*) AS rowsNum
                      FROM I.tbname;
                      
                 numberOfRows currentTableRowCounter%ROWTYPE;
            BEGIN
                 OPEN currentTableRowCounter;
                 FETCH numberOfRows INTO numberOfRows;
                 CLOSE currentTableRowCounter;
                 
                 IF (numberOfRows.rowsNum > 10000) THEN
                      -- And here I will call the procedure which has to be run
                 END IF;
            END;
       END LOOP;
  END;
  /

  I already checked this code with tables inividual and it works. The only problem is
  

  . . .
  SELECT COUNT(*) AS rowsNum
  FROM I.tbname;
  . . .

  Indeed, oracle considers "I.tbname" as an unknown table name (although he refers to by its exact name).

  SQL> @script.sql
  
                                  FROM I.tbname;
                                         *
  ERROR at line 99:
  ORA-06550: line 99, column 12:
  PL/SQL: ORA-00942: table or view does not exist

  How can I solve this problem? I mean, how to use a variable (in my example, I.tbname) as the table name in the FROM clause to query a table instead of explicitly write the name of the table?
  
  
  
  
  
  Thanks in advance,
  Dariyoosh

  Replace the following code:

            DECLARE
                 -- Here I declare a cursor for counting the number of rows
                 CURSOR currentTableRowCounter IS
                      SELECT COUNT(*) AS rowsNum
                      FROM I.tbname;
  
                 numberOfRows currentTableRowCounter%ROWTYPE;
            BEGIN
                 OPEN currentTableRowCounter;
                 FETCH numberOfRows INTO numberOfRows;
                 CLOSE currentTableRowCounter;
  
                 IF (numberOfRows.rowsNum > 10000) THEN
                      -- And here I will call the procedure which has to be run
                 END IF;
            END;
  

  By the following:

  Declare
    numberOfRows number;
  begin
    EXECUTE IMMEDIATE 'select count(*) from '||I.tbname into numberOfRows;
  
    IF (numberOfRows.rowsNum > 10000) THEN
      -- And here I will call the procedure which has to be run
    END IF;
  end;

• Some doubts about the navigation in unifying

  Hi all

  I had a few questions about unifying navigation.

  Is it possible to move the admin mode user mode access level?

  I mean, if a particular feature as Manager of the shell I can only access from admin mode is it possible to provide access even in user mode?

  If so, how?

  My 2nd question of doubt is, currently, we can access company BPs level "Journal of society" or "Resource Manager" under shell 'Company Workspace'.

  Is it possible to move the "journal of the society" or "Resource Manager" in the folder? If yes how?

  I tried in "navigation user mode" to move the company BPs level at shell of the House, but I can't do it.

  To answer your questions:

  (1) User-Mode browser can have the user feature included. You cannot change the view mode Admin or move functions admin for user mode.

  (2) you cannot move these on the Home tab.

• Doubts about the speed

  Hello gentlemen;

  I have a few questions, I would like to ask more experienced people here. I have a program running on a computer that has a processor i7 processor. In this computer that I have programmed in LabVIEW, meanwhile in another lab, we have another PC, a little older, a dual core 2.3 Ghz, in this pc, we perform a testing platform for a couple of modems, let us not get into the details.

  My problem is that I discovered recently that my program, I programmed in the computer, i7, much slower work in the other machine, the dual core, so the timings are all wrong and the program does not run correctly. For example, there is a table with 166 values, which, in the i7 machine are filled quickly, leaving almost without delay, however, the double machine heart, it takes a few milliseconds to fill about 20 values in the table, and because of the timing, it can fill more values and so the waveform that I use is all wrong. This, of course, live of the whole program and I can't use it as a test I need to integrate.

  I have create a .exe program in labview and try it in the different PC that's how I got to this question.

  Now, I want to know if there is actually a big problem due to the characteristics of the computer, the program is slow in one machine. I know that, to ensure the eficiently program, I need to use States, sub - vi, idea of producer-consumer machines and other things. However, I discovered this is not a problem of the speed generated by the program, because, if that were the case, the table would eventually fill it completely, however in slow computer, it is not filled more with 20 values.

  Else, helps to hide unnecessary variables in the front panel?, because the time beeing I have keep track of lots of variables in the program, so when I create the .exe I still see them runing to keep this follow-up. In the final version, that I won't need them so I'll delete some and hide front panel some. It helps that require less condition?

  I would like to read your comments on this topic, if you have any ideas in machines to States, sub - vi, etc., if there is a way to force the computer to use more resources in the Labview program, etc.
  I'm not add any VI because, in the current state, I know you will say, state machines, sub.vi and so on, and I think that the main problem is between the difference in computers, and I'm still working in the things of the State/sub-VI/etc

  Thank you once again, we just let this hollow.

  Kind regards

  Get started with, using suitable as a machine for States stream you can ensure that your large table would be always filled completely before moving on, regardless of how long it takes. Believe it or not add that a delay to your curls will do more all the program run faster and smoother, because while loops are eager and can consume 100% of CPU time just a loop waiting for a button press, at the same time all other processes are fighting for time CPU.

• Doubts about the migration parallel to Lync 2013-> Skype4B 2015 on VCS - C (not clustered)

  Hello everyone!

  As I saw on Cisco documents, applying "B2BUA/Microsoft Interoperability" on VCS can "communicate" with just an instance Microsoft Lync pool servers, but we need to migrate the Lync server on parallel to the servers of Skype, we need to have a few "maintenance window" to migrate all users!

  Can we keep 'UP' communication for VCS (lync and Skype) pool of two servers until the end of the migration? The lync Server legacy 2013 (shared resources) with VCS today can communicate with users (migrated) for 2015 of Skype with trunk Lync existing TLS today?

  I think we generate another certificate for TLS and affecting some Skype server on the option "host approved", that's okay, I forgot something? Or I have other ways to communicate two pools Microsoft server with a VCS - C with the application "B2BUA/Microsoft Interoperability?

  Thanks for help me!

  To see some possible examples of deployment options, refer to Appendix 3 of the infrastructure Microsoft (X8.8) Deployment Guide and totalled, suggest that you also look over the guide in full as it might answer some of your questions about what is supported.

• doubts about the css class...

  I tried to load a background image in the theme universal apex 5 in the login page.

  and I used the code found in the following link and got it works

  Apex 5.0: Theme Roller and background image

  But I doubt that can be very simple for the css professionals.

  .t-PageBody-.t-body connection

  {

  Background: URL("Sports.jpg") repeat top center white scroll;

  Color: #000000;

  do-family: Arial, Helvetica, Sans-serif;

  do-size: 12px;

  line-height: 17px;

  }

  .t - PageBody.t - body

  How do you know .t-PageBody - .t-body connection was the main class to change...

  Let me know if my interpretation is correct

  .t-PageBody - login is the main class

  and .t-Body is the upper class?

  .t-PageBody--login .t-Bodyis a descendant selector. It matches any element with a class attribute that contains a t-Body value having an element ancestor with a class attribute that contains a t-PageBody--login value. There is no concept of 'main' class or 'slot' in CSS. The required selector is likely to have been determined on the supplement page using a web Inspector.

  It is advisable to take some tutorials to get at least a basic understanding of web technologies when you work with APEX.
