• How to pass the value of the cursor in the procedure to use as dblink

  Hello

  I have a cursor in the procedure. I am inserting some values into the destination table by querying the source table using dblink. And I'm collecting this db link in the cursor. So, my question is how I will pass on the value of dblink values read from the cursor in each iteration? This is my procedure.

  CREATE OR REPLACE
      PROCEDURE desktop_proc
      AS
        v_name VARCHAR2(10);
        v_dblink  VARCHAR2(10);
        CURSOR db_cur

          ORDER BY PNAME;
      BEGIN
        OPEN db_cur;
        LOOP
          FETCH db_cur INTO v_name,v_dblink;
          EXIT WHEN db_cur%NOTFOUND;

• How the index data are managed within the cluster?

  Hello

  Regarding indexes, am I right in thinking that the data in the index are stored in a (managed internally) cache on the same node that the attendant at the following indexed values? I'm not interested in getting the data in the index, but rather just to understand how the data in the index itself are stored or processed within the cluster.

  Hi Peter,.

  up to 3.4.x index have been supported only on partitioned topology, and Yes, the index on each node contain only the data corresponding to the entries that have their main copy on this node (referred to as entered local subsequently).

  The indexes are not stored in a cache, but they are managed under the information that maintains consistency in terms of backup (the map that contains local entries).

  The indexes are in 2 parts:

  -index to the front: this is a mapping of the cache key in an internal representation (Playback key card in the future) the value extracted with the extractor used to create the index of the entry to membership of the cache key (value extracted later)

  -reverse index (aka. reversed card): this is a map of the value extracted from a backup set of the keys of the map of entries which we extract the index key reversed with the extractor used to create the index

  The index can be sorted, which means that the index reversed a SortedMap (sort order is the order of the extracted values)

  Let's see an example. Assuming you have the contents of the following cache within a particular extension storage node:

  A--> Object (PositionX = 5,...)
  B--> object (getA = 3,...)
  C--> object (getA = 3,...)
  D--> object (getA = 4,...)

  The index forward in this node will contain:

  Binary (A)--> 5
  Binary (B)--> 3
  Binary (C)--> 3
  Binary (D)--> 4

  The reverse index will contain:

  3--> {Binary (B), Binary (C)}
  4--> {Binary (D)}
  5--> {Binary (A)}

  Where Binary (...) designates the internal representation (binary) of the... object.

  If the index is not ordered, then the order of iteration over the entries in the index reversed are not deterministic.

  If the index is ordered, the iteration of the entries into the inverted index will be as stated above. Also, you can convert the SortedMap inverted index in order to have the very useful headMap and tailMap and firstKey and lastKey methods.

  I hope this helps.

  Best regards

• How to get data hardbounce retrospective of the most recent date?

  I want out of backdata Hard bounce by last date using the API.

  Can someone help me?

  Any suggestion is appreciated.

  Kind regards

  Shashi Kant

  BLOCK has an API "/ activities" endpoint, you can use to define an excerpt. You can programmatically add a filter him every time you kick off your snippet (something like ActivityDate > = and set the current date as the side right of the > = parameter). You can then use the ' /extracts/data "endpoint to extract the data returned by eloqua sync. See the documentation for the API BLOCK to get an idea of a typical eloqua extraction process.

• Invalid cursor within the service in pipeline

  The simple example following illustrates a mistake that I am experiencing with development code more complex.

  I try to reuse a complex procedure that I do not have duplication of code and business logic.

  It runs correctly.

  I checked and the cursor is opened and % notfound is false.

  Any ideas?

  Problem is that your variable v_cursor in SELECT_ROWS is out of scope when the procedure ends.

  So the ref cursor returned by this method cannot be referenced it more.

  If you are on 11g and beyond, a workaround is to declare v_cursor DBMS_SQL cursor (for example an INTEGER data type) and use DBMS_SQL.to_cursor_number / DBMS_SQL.to_refcursor to convert between the two.

  In this way, the query pointed to by the final Ref cursor will always have a valid binding variable when the procedure ends.

  function select_fn( p_cursor in integer )
  return PKG_TEST.t_tab pipelined

    v_tab         PKG_TEST.t_tab;

       for i in 1 .. v_tab.count
       loop

• How to get data that are created the or before the last Wednesday

  Hi, can someone please tell me how to write a query to retrieve the data that are created the or before last Wednesday.

  Thanks in advance...

  Hello

  Here's one way:

  WHERE created_date< next_day="" (="" trunc="" (sysdate="" )="" -="">

  , "THURSDAY".

  )

  "Before Thursday' means the same as 'the or before Wednesday '.

  This assumes that NLS_DATE_LANGUAGE is English.  If you are not sure what is NLS_DATE_LANGUAGE, you can do this:

  WHERE created_date< next_day="" (="" trunc="" (sysdate="" )="" -="">

  , TO_CHAR (DATE ' 2014-03-06' - or any Thursday)

  , 'DAY '.

  )

  )

  There is nothing magical about March 6, 2014; will do any Thursday.  To_char will return the translation of 'Thursday' in all that is the current NLS_DATE_LANGIUAGE, and NEXT_DAY can use this value.

• How to change data objects and update the corresponding task and task forms?

  Hi all
  
  I modified this thread because I found that I had many questions to ask.
  
  1.
  I'm quite new to OBPM and would like to know how to change data - for clarity objects add a new attribute "Dependents of the Client" "Customer care" - and therefore update the task that uses the 'customer information' what makes via data binding - I get an error message here - or via the data about the data Task-The chosen tab it does not appear to be linked to my approach in some sort.
  
  2.
  Will be the task form that I generated earlier in < 1 > update automatically? Is it possible to update manually if the task has been clearly customized?
  
  3.
  What are the objects of project data? They do not store values in my process. They are for the arguments only - like reusable process?
  
  Thanks in advance,
  
  Kind regards
  
  Yanis

  Hi Yanius,

  (1) assume that you start from scratch. First, you declare your data object structure. To do this, you must go to the BPM project Naviagtor, right-click on 'Catalogue of trades' and create a new Module. Then you can right click on the module you created and select the new object of trade. Add all the attributes you need. It is the same to declare a class in Java. Second, you must declare a variable of the type process you have created: select the process, go to the Structure display (if you don't go and activate it in menu view Jdev-> Structure). Right click on the Process data object and create your variable. It's like setting a variable in Java. In short, answering your question, make the path opposite: find in your process of type "Customer Details", then go to your catalog Business, right click and change the definition to add what you need.

  (2) the human task will not update automatically (annoying). If you change the object itself, so you don't need to change your mappings because actually there the same object you are through the task as in / out argument. There are two things here: the human task and form associated with it (where probably change you the subject i.e. customer details). Go to the form (.jspx) - click on the tab links (by default, you are in the Design). In the links page, there is a link on top: "Page Définition File" (something like proj/pageDef/...xml). Open the XML file and go to the source. There you can add manually now all the attributes you need and that were not available before (i.e. dependent Client). It's a little complicated, but at least you don't have to recreate it. particularly useful if you have already implemented and subsequently form, you need to add more things (business is very good to say otherwise, "I would like to see something else in the form" ;)

  (3) project data objects are visible by all processes that you have in the project rather than the object of process data that are visible only to the method where you set the variable to. This means that you declare an object of data of the project once and then it will be available to all processes. Keep in mind that each process has a copy of it. In other words, it is not like a global variable that everyone sees. If edit you in a single process, other processes will not see the new value.

  I hope that I have answered your questions.
  See you soon,.
