• How to find the redo generated by each SQL statement?

  Is it possible to know which statement sql generates how many redo in bytes for a moment?

  It will not help you.
  For example, you can see a lot of UPDATE, DELETE, INSERT from the apps statements. Then? What you do with them? If you can modify the application to eliminate the useless LMD - it would be great of course. But it is unlikely.

  When the DML statements also generate Redo, does not cause them too much expectations "log file sync", because the writer log buffer empty buffer as soon as it fulfills more than 30% after a certain time or on Commit / Rollback.

  Waiting on event "log file sync" during the execution of operations of COMMIT and ROLLBACK consumed at the time of the important data.

  Right. This is because the writer written newspaper here synchronous, reliable, he waits until the HDD writes data down and meets its written OK.
  And hard drives are not the fastest things in the computer. They are mechanical - that's why.

  I would recommend:
  1. place files redo log on quick drives used preference dedicated only to this end. If other I/O will often disturb these readers resulting securities heads change causing longer HDD expected.
  2 consider using faster technology such as SAN or SSD.

  Take a look at this one:

  especially the chapter on the block that contains a collection of (2.3.3). The sample is built around a nested table, but you get the idea to adapt to work with a varray.

• the number of refills for SQL statements

  Hello
  in 10g R2, how to see the number of refills for SQL statements? Any question? High value? What earned is low?
  
  Thank you.

  First run a statspack or AWR report and take a look in v$ librarycache

  Numbers are irrelevant. The reports are a little more relevant, but not necessarily a problem.

  kindly tell how to use the unique value of a table with the index 0

  Hi
  
   
  
  Yep, use Index Array as Gerd says. Also, using the context help ( + h) and looking through the array palette will help you get an understanding of what each VI does.
  
   
  
  This is fundamental LabVIEW stuff, perhaps you'd be better spending some time going through the basics.

• How to use the global variable in the table target?

  Hello

  I am trying to load several files into a single interface. the data is loaded successfully. 92. the files are there. for this I used variables and package.

  My requrement is 92 files of data loaded into the target table. I want to know what data from file.

  to this I added a column (filename) to the existing target table.

  If I used joints (not same condition), its totally wrong. all file names are coming.

  Please see the following screenshots.

  

  exit; target table.

  

  in fact in the target table. first 10 lines are coming from file.i.e first _ACCOUNT_LIMIT_511.TXT. but all the files names are coming.

  I'm confuse. After the first data file inserted then insert second data file. in that all file names are coming. Please help me.

  I thought that the global variable is preferable to identify the data came from which file.

  to do this, the global variable is used in the target table. I don't always have my exit.

  Please help me.

  Thanks in advance.

  

  Hello

  You can use the same way, how you use the project variable, just you have to do a thin is #GLOBAL.variable_name for example: #GLOBAL. SMART_AL_FILE_NAME_S

  Note: Make sure you that while you use one variable overall in interface, indicator should be staged as you chose above the screen

  hope this helps you

• using the function - how to use the values of the input variables on the table select statement names

  Hello community, I have a problem when creating a function. The purpose of this function is to check the table of weather gave yesterday or not. We must check this on different tables on different sachems. We are creating a function with input variables.

  When creating, I got error: [error] ORA-00942 (44:19): PL/SQL: ORA-00942: table or view does not exist

  How to use the values of the input variables on the table select statement names?

  Hello

  Here's a way you can use dynamic SQL statements for this task:

  CREATE OR REPLACE FUNCTION IS_YDAYDATA_TO_TABLE

  (

  in_schema IN VARCHAR2,

  in_tablename IN VARCHAR2,

  in_datefield IN VARCHAR2,

  in_first_date DATE DEFAULT SYSDATE - 1,.

  in_last_date DATE by DEFAULT NULL

  )

  RETURNS INTEGER

  AS

  -IS_YDAYDATA_TO_TABLE returns 1 if in_schema.in_tablename.in_datefield

  -contains all the dates in the in_first_date of the range through included in_last_date

  - and it returns 0 if there is no such lines.

  -If in_last_date is omitted, the search only the data on in_first_date.

  -If in_first_date is omitted, it defaults to yesterday.

  -Time parts of the in_first_date and in_last_date are ignored.

  -Declaring variables

  sql_txt VARCHAR2 (1000);

  v_is_true INTEGER.

  BEGIN

  sql_txt: = 'SELECT COUNT (*).

  || 'FROM ' | in_schema | '.' || in_tablename

  || 'WHERE ' | in_datefield | ' > =: d1'

  || «AND» | in_datefield | '< >

  || 'AND ROWNUM = 1';

  dbms_output.put_line (sql_txt |) '= sql_txt in IS_YDAYDATA_TO_TABLE");  -For debugging

  Sql_txt EXECUTE IMMEDIATE

  IN v_is_true

  With the HELP of TRUNC (in_first_date) - d1

  TRUNC (NVL (in_last_date

  in_first_date

  )

  ) + 1                -- d2

  ;

  RETURN v_is_true;

  END is_ydaydata_to_table;

  /

  DISPLAY ERRORS

  If you must use dynamic SQL statements, put all the SQL statement in a single string variable, such as sql_txt in the example above.  In this way, you can easily see exactly what will be executed.  Comment out the call to dbms_output under test is completed.

  Try to write functions that will address not only the question that you have now, but similar questions that you may have in the future.  For example, now that interest you only to the verification of the data of yesterday, but later, you might want to check another day or range of days.  The above function combines the convenience of a function simple (looks like yesterday data if you don't tell him otherwise) with the power of a more complex function (you can use the same function to check any day or range of days).

• How to use the error at the level of the mapping table?

  Hi all
  
  Please tell me how to use the errors table in the mapping level or how to handle errors in mapping.
  I create a table of errors in oracle, but I don't know how to use it in the map.
  
  
  Thanks in advance.
  
  Kumar

  Hi Kumar,

  You use the Table of errors with the data rule.

  Error tables are used with logical errors (data rules) managers. Detailed description on the use of data rules is explained in the following document

  http://www.Oracle.com/technology/products/warehouse/PDF/OWB10gR2_ETLandBusinessRules.PDF

  In a nut shell, use of the tables of the error is the following.

  1 create a rule of data associated with a table (target table or a table in which you load data).

  2. use the table in a map as a target table.

  3 deploy the table and mapping.

  Now, in the schema target a single table will be created with the name _ERR. When executing a mapping data that violate the rule of data enters the error table.

  The following must be done to have the name of the wrong choice of the customers table.

  1. right click on the table and click Configure.
  2. give the name of the table in the section "name of the shadow table.
  3 pull out the table.
  4. use this table in a map. Now in the mapping on this table properties in the section 'Error Table name' the name of the table that is specified in 'the shadow table name' will be fulfilled.

  Thank you

• How to use the Group condition in the ODI mappings

  Hi Experts,

  I have a requirement in the customization of BI applications. Can you please someone explain how to use the LISTAGG function in odi mapping.

  I applied the LISTAGGR function at the level of mapping odi, but I get error below.

  Mapping of ODI: ColumnName: ENAME Expression: LISTAGG (EMP. ENAME, ",") THE GROUP (RANKING BY EMP. ENAME)

  Error:

  ODI-1240: Flow LIST_AGG_FUN_USAGE fails during an operation of integration. This flow of charge table target EMP_BI.

  ODI-1228: task failed LIST_AGG_FUN_USAGE (integration) on the scott_db of ORACLE target connection.

  Caused by: java.sql.SQLSyntaxErrorException: ORA-00937: not a function of simple-group

  
  

  Oracle query:
  

  If I used this sql query in the database the correct result is.

  SELECT DEPTNO, LISTAGG (ENAME, ',') WITHIN THE EMP EMP (ENAME CONTROL) GROUP. DEPTNO;

  Output:

  10	CLARK, KING, MILLER
  20	ADAMS, FORD, JONES, SCOTT, SMITH
  30	ALLEN, JAMES, MARTIN, BLAKE, TURNER, WARD

  
  

  Please give your valid solutions, thanks in advance.

  Kind regards

  REDA

  If you try in #ODI12C then in the set of properties, you can select the column which should be used to group by.

  If it's 11g so its bit complicated. Simply replace the mapping with below codes.

  LISTAGG (EMP. ENAME, ",") WITHIN GROUP (ORDER BY ENAME) / * sum() * /.

  Magic!

  Thank you

• How to use the functions of SetValue executeScript activity.

  Hello

  Could someone let me know how to use the function activity setValue (serialize concate, count etc) in activity executeScript. What all liberaries I need to import to executeScript. I want to perform the same task in executeScript performed in the setValue activity.

  Concerning

  Sunil Gupta

  Forgive me if I seem obtuse, but why would you use XPath functions (is that serialize, concat, and count) when there are perfectly good Java alternatives that will be much easier to use.  Java is, after all, the language used in the executeScript.  Serialize is just toString(), CONCATENATE is just + or. concat() (I assume that you are running on Java 6 web application server).  The count function is just the length() or size() methods or to the tables, the length property.  If you really need to reorganize in a variable of the XML data using a XSL stylesheet - you have access to all the functions in XPath 1.0 and XPath 1.0 power and you do not need to tinker with the headache of trying to debug Java in an environment (Workbench), which does not give you the tools that you would normally , as a contextual Editor.

• How to use the search otherwise condition as

  Oracle 9i
  
  Hi all
  
  I work in the management of control here, we have a table named as OE_ORDER_LINES_ALL and the name of the column called UPI, and its length is 16 tank.
  
  Now the customer has the UPI with 13 tank and now, I need to check if all the IPUS are in the table.
  I have almost 600 of the UPI and I can't able to use as an operator. Y at - it one option other than as an operator.
  
  For example
  
  Resemble UPI this 050 009714373007G, but the customer gave this G 009714373007.
  
  Is there a UPI then I would use like this
  
  "Select upi in oe_order_lines_all where the upi as ' 009714373007 G %.
  
  If there is more than 2 UPIs how to use the search condition
  
  Any help is highly appricatable
  
  Thanks and greetings
  Srikkanth.M

  If you know that you will benefit from a number of values of UPI 13 characters and you should look for if there are rows in the table that match the 13 first characters

  select upi
    from oe_order_lines_all
   where substr(upi,1,13) IN( '009714373007G', <> )

• How to use the LrPublishService Namespace?

  I can't get the LrPublishService to work so I can access its functions.  I see nothing wrong with what I'm doing, I hope someone can point out what I am doing wrong or if I misunderstood something in the docs.

  That's what I have my code:

  local LrApplication = import 'LrApplication'
  
  local LrCatalog
  local LrPublishService
  
  LrTasks.startAsyncTask(
       function()          
       LrCatalog = LrApplication.activeCatalog()
       LrPublishService = LrCatalog:getPublishServices(_PLUGIN.id)
          LrPublishService:createPublishedCollection('My Sample Collection')
       end, --end async function
       'publish service test'
  ) --end async task
  

  Lightroom throws the error ' attempt to call method 'createPublishedColection' (a nil value) when you try to run this line of code: LrPublishService:createPublishedCollection('My_Sample_Collection').

  The table returned by LrCatalog:GetPublishServices() looks like {{}} when I convert it to a string.  I am confused on how to use the LrPublishService namespace.  I want to do ultimately is to create publish collections programmatically when the user creates a new service.

  Any help is greatly appreciated, thank you.

  Catalog: getPublishServices should return a table.

  It seems you are trying to call a function on this table, rather than in an instance of LrPublishService it contains.
