• IKM slowly changing dimension problem

  Hi guru,.
  
  I use the IKM slowly changing the size of the target staging.
  
  In the target tab Description table, I have updated with the behavior of slowly changing according to the requiremnet as dimension
  a few columns like - add on the change of line
  a few column as - crush on changes
  
  and KEY columns and timestamp of the start and end date.
  
  Now my problem is when change came in the box (add on line change column) after the execution of the interface I do not get the update for the existiing line or new line.
  
  
  only with the combination of (Overwrite on change) & Add on change of line is changed... then only the new line is inserted to target...
  
  
  Thank you

• Load with the incremental update of the IKM Oracle

  Hi Experts,

  According to my understanding, incremental load is that the new data (with insert append or load incremental (update/insert or merged with or without behavior SCD)).

  While peek into the code of the IKM KM here it is my understanding:

  Incremental update: given the PK defined in the target data store, that KM will check line by line and put insert/update (change data capture).

  Append: Blindly block for the table insertion target and any changed data will be captured. It will not truncate and insert so that to avoid duplicates in the data, have a PK defined in the target table, so whenever the duplicate data comes it can be prevented or go for CKMs.

  
  

  Now my doubt is,

  
  

  When you use the incremental km update: the scenario is I have an incremental load today, inserted for example 200000 files today and tomorrow other 200000 records added (may include updates of certain lines in the previous loaded 2,00,000 documents. Now it will scan 4,00,000 (yesterday + today) and seek changes, I mean to update or insert

  Because according to my understanding will treat this KM row by row all records (my understanding is correct?). If it reads each record and are looking for a change or not change it seems to me that his time and performance issues?  CDC is right approach in this scenario or the implementation of SDC on all columns in the table?

  
  

  Regarding the large number of records coming daily, updated incremental if IKM checking all records for update or insert or no change, in my opinion, this isn't a performance wise and time to compare source and target value. This KM eliminate comparing itself the Chronogram of the source to target those who does not charge any change in any of the previous column value?

  
  

  
  Sorry if this is a silly question. Just trying to figure which can be better charge strategy, especially when I have millions of records entering source daily.

  
  

  SSX I remember ealier JeromeFr our expert member in the community, said Partioned Exchange to treat only to process the given month data when you manage tables partitioned at the database level.

  Hi ASP_007,

  Charge, as opposed to full reload, does indeed only new (and possibly changed) data. There are 3 main ways to do this:

  • Set up a filter in your mapping interface/load only the data including the upper date to a variable (which holds the last loading date).
  • Use the framework of the CDC in ODI. There are several JKMs. The solution optimal is probably the Golden Gate, one, but you must purchase this additional license. mRainey wrote about this several times: http://www.rittmanmead.com/2014/05/goldengate-odi-perfect-match-12c-1/
  • Retrieve all the data in the source and allow an incremental update of the IKM define what already exists.

  Of course, the first two still will take a little more time to develop, but it will be much faster in terms of performance because you treat data less.

  It is for the part "Extract", get data from the source.

  Now, you must know how to "integrate" into your target. There are different strategies as insert Append, incremental update, Type 2 SCD...

  • Indeed insert Append won't update. It will only insert lines. It is a good approach for a full charge, or for an additional charge when you want to insert data. There is an option in most of the IKMs Append (control) to truncate the table before inserting (or delete all the lines if you do not have the privileges to truncate).
  • Incremental update: there are different IKMs for this and some may have better performance than others depending on your environment. I recommend you to try a few and see which is more fast for you. For example ' IKM Oracle incremental update (MERGE) "could be faster than 'IKM Oracle incremental update. I personally often use a slightly modified version of ' IKM Oracle incremental update (MERGE) for Exadata ' to avoid using a work table (I$ _) and perform the merge directly into the target table. The last approach works well with the CDC when you know that all data are new or changed and needs to be treated.
  • SCD2: To maintain your dimensions needing SCD2 behavior.

  So in answer to your questions:

  Because according to my understanding will treat this KM row by row all records (my understanding is correct?). If it reads each record and are looking for a change or not change it seems to me that his time and performance issues?

  Some of the IKMs will do it line by line, others will do it based on a game. This is why it is important to check what he does and he spots.

  CDC is right approach in this scenario or the implementation of SDC on all columns in the table?

  Yes certainly, you will have less data to be processed.

  Regarding the large number of records coming daily, updated incremental if IKM checking all records for update or insert or no change, in my opinion, this isn't a performance wise and time to compare source and target value. This KM eliminate comparing itself the Chronogram of the source to target those who does not charge any change in any of the previous column value?

  Yes, by using ' IKM Oracle incremental update (MERGE) for Exadata ' with the strategy of 'NONE '. This means that he will not try to see the rows from the source is already in the target.

  PS; I am remember ealier JeromeFr our expert member in the community, said Partioned Exchange to treat only to process the given month data when you manage tables partitioned at the database level.

  It is a good approach when you want to reload an entire partition (if you have a monthly charge in a monthly partition or a daily load in a daily score for example). It is easier to set up to load the new lines only. But if you need to update things in the source, you can use incremental update strategy on an intermediate table that contains the same data that your partition and then create the swap partition in a further step.

  Thanks for the mention.

  Be sure to close your other discussions.

  It will be useful.

  Kind regards

• Slow Changing dimension Interface fails at the step of the update

  Hello

  I've created an interface dimension slow evolution and it is a failure on the update.  When I go through the code generates the error, there are no columns identified to be updated.  Do not know what is happening...

  Ideas?

  Thank you

  It seems that you don't add any column as "crushed on change" to the field slowly change behavior Dimension in the Description of the data model tab.

  Please take a look at this topic SCD in this Oracle (SCD research) document:

• Where can I find the code of the IKM Oracle Merge.GLOBAL

  Hello

  I use odi 12 c and I'm trying to set the transaction (for example ' Transaction 0') and commit option (no validation) for the task of integration when "IKM Oracel Merge.GLOBAL" is selected as the knowledge of integration module.

  Unfortunately I can't find the module in the imported knowledge modules, so I can't customize, as for example the 'IKM Oracle incremental update".

  Do you know where I can find its definition and make a copy?

  The description of the module is the following:

  NAME of the COMPONENT: IKM Oracle Fusion

  VERSION OF THE COMPONENT: 12.1.2.0.0

  AUTHOR: Oracle

  COMPATIBILITY: ODI 12.1.2.0.0 or higher

  DESCRIPTION:

  Oracle KM MERGE statement

  Thank you!

  Sorry, Yes, you're talking about the IKM is built in and so probably cannot be changed. However, the incremental update of Oracle IKM (MERGE) provides essentially the same functionality but also supports flow control, so I would use this KM as the basis for what you want to do and throw the built-in function.

• difference between the incremental update of the IKM oracle and incremental update IKM oracle (PL - SQL)

  Hello

  What is the difference between the incremental update of the IKM oracle and updated incremental IKM oracle (PL - SQL) and incremental update IKM oracle (line by line).

  Thank you

  Papai

  The only difference is that the second using plsql for incremental update. He also to manage clob issues well enough.

  If you need to know more you can read the description of each KM section.

  Incremental update IKM Oracle (PL-SQL)

  -------

  Description:

  -Knowledge integration module

  -Integrates data into an Oracle table from target in incremental update mode using PL/SQL.

  -Non-existent rows are inserted. already existing lines are updated.

  -Data can be controlled. Data invalid are isolated in the error Table and can be recycled.

  -This KM uses PL/SQL to perform the inserts and updates until and blob columns are supported. Please see the restrictions.

  -When you use this module with a source table logged, it is possible to synchronize the deletions.

  Restrictions:

  -When working with the logged data, if the "synchronize destruction of the newspaper" are executed, the lines deleted on the target are engaged

  -The data are updated even if not changed (upgrade from any (e)

  -The number of lines (number of inserts/changes) is not available because the transactions are performed using PL/SQL

  -Comparison of the data is performed using the key to update defined in the interface. It must be set.

  -L'option TRUNCATE does not work if the target table is referenced by another table (foreign key)

  -Options FLOW_CONTROL, and STATIC_CONTROL call the Module knowledge check to isolate invalid data (if no CKM is defined, an error occurs). These two options should be set to NO in the case where an integration Interface meets a TEMPORARY target data store.

  -L' FLOW_TABLE_OPTION option is set by default to NOLOGGING. Set it to a space if the interface is running on an Oracle 7 database

  -Deletions are committed regardless of the VALIDATION option

  -Default UPDATE option is TRUE, which means by default it is assumed that there is at least one column nonkey specified in a target data store.

• Change the Type of the attribute at the request of the View object

  Hi all
  
  I use JDeveloper 11.1.1.6. I am trying to achieve the following problem.
  
  My Table has a column of type VARCHAR2, but this field is to store, say, displayed in canonical format "YYYY/MM/DD hh '. I want to show the date in a nice format, as October 30, 12 ' and be able to use the datePicker adf (date. MinValue) on the attribute.
  
  So I created an entity object, and I changed the type of the attribute of Date String.
  
  I also created a ViewObject and the test on request module retrieves a date but seems to not understand the canonical format and date it recovers is wrong (something like 5049-02-20 12:45:30.45).
  
  Since then, I work on EBS I oracle API access and so on, so I changed my query View object;
  
  SELECT St St myEO.ExpiryDate-> FND_DATE.canonical_to_date (myEO.ExpiryDate) SELECT as displayed in St St. (FND_DATE.canonical_to_date would be the same thing as to_date (date, format))
  
  When I run AppModule, NICE! It works, it retrieves the date without time and if simple format to give the attribute I can even get the format I wanted.
  
  The problem is that when I try to update and validate changes to DB, (I replace the doDML so I can analyze my Date to a string with the format YYYY/MM/DD hh: mm: as is supposed to be) I can't even the part update. Complains in the framework;
  
  Invalid state, another user has changed the line and blah blah blah and the problem is here:
  
  (oracle.jbo.RowInconsistentException) Houston-25014: another user has modified the line containing oracle.jbo.Key [592674 primary key].
  
  
  [178] compare entity did not attribute display
  [179] original value: 2013-06-28 (that I ran with my FND_DATE.) Procedure CANONICAL_TO_DATE)
  [180] target value: 5048-02-21 22:47:53.0 (I guess that the automatic distribution or conversion of the original string)
  OracleSQLBuilder [181]: ROLLBACK WORK point registration "BO_SP".
  [182] DCBindingContainer.reportException: oracle.jbo.RowInconsistentException
  
  Any suggestion? I'd really appreciate it.
  
  Edited by: Alejandro T. Lanz on 1st November 2012 06:34

  Well, in short :):
  When you try to update the line, frame checks the data in db and cached (from the entity object) value is different from the db value (because you Date and String objects), so that it will throw oracle.jbo.RowInconsistentException exception.

• How to change the type of object?

  I have an object type, as shown below:
  
  Here are the object and its type

  Any body could help for the alter script.
  
  Thank you
  Lavan

  >

  >
  Which won't work OPs example. Your example does not include the second type of object that depends on the first type.

  You cannot change the underlying type unless you use the CASCADe or INVALIDATE option.
  >
  change the type of test_object1 change attribute (val1 varchar2 (100)) waterfall;
  >
  See the CASCADE clause in the link provided by Osame
  >
  CASCADE clause

  Specify the CASCADE clause if you want to propagate the type change to the tables and dependent types. Oracle database abandons the statement if errors are found in the dependent types or tables, unless you also specify the FORCE.

  If you change the property of the type between FINAL and NON-FINAL, you must specify this clause to convert data in the tables and dependent columns. Please refer to [NOT] FINAL.

• Query regarding changing the type of human task

  Hello
  I'm new to BPM. I created a process to two tasks and selected by mistake the two human tasks with the motif of the initiator. And now I get this compilation error that says my process contains several tasks of initiator. Is there a way I can change the type of simple human task after the process has been created?
  Thanks in advance

• Change plan type assignments

  After the planning database structures have been created, is it possible to re - assign a type of plan for a given hierarchical member?
  
  For example: account is currently set to Plan Type 1. What happens if the company decides it wants to move either completely in the model Plan 2, or shared it with the two Plan Type 1 and 2?
  
  The screen change the Dimension shows as active Plan Type 1, but other types of plan are grayed out.
  
  
  Thank you!

  It is possible to do with the accounts, it must be remembered that the Member takes the properties of its parent, so if its parent is set to be valid against only plan type1 then you can't change child members source the type of plan or have additional plan types.
  You must have a look at the structure of your account because he's working on down, it is possible to change the types of plan and plan source types.

  See you soon

• Change the type of sensor pressure strain for SCXI-1314

  Hello!

  I would like to ask how to change the type of strain sensor.

  I use SCXI-1314 and one of my pressure sensor is a type of 4-wire. (Output 100mV, excitement: 10vdc)

  , but I want to replace the sensor by another type of current output type. (Output 4 ~ 20mV, excitement: 12-30Vdc)

  I checked the output voltage cable 4. (Defined as full-bridge OR max)

  Power + = Ex +.

  Food - = Ex-

  CH+        =  S+

  CH-         =  S-

  However, I don't know how to connect the type 2-wire with SCXI-1314.

  In addition, I don't have enough experience on the types of bridge (bridges and whole, quarter half)

  Can you explain what I need to do?

  One thing you migth try is to put a 5 Ohm resistor in the current loop. causing a drop in voltage 100mV on resistance, however check the soil conditions.  Since you will need a new calculation of sensitivty sensor anyway you can use a resistor 4.7 Ohm or 2 10 ohms in parallel... just find a good match between your 1314 input voltage range and the 4-20mA.

  And you will have an external power supply for the sensor.

• Can you change the type of device to 'USB Raw resource' to GPIB controller?

  I'm trying to configure a GPIB FL Contec GP - IB (USB) controller in MAX.  I could so he can register through the creation of a pilot of the Assistant driver VISA, but it fits as a "gross resource USB" rather than as a GPIB controller.  I can send and receive information from the controller, but it does give me an option to search for connected devices of GPIB communicate with them.  Is it possible to change the type of the device, maybe by manually changing the driver created by the wizard of the NI-VISA driver?  Thank you for your time.

  N ° do not use MAX at all. You can just create a GPIB-USB controller on your own. You should contact the seller.

• Change the type of serial number of UUT
