Mapping algorithms in data integrator

Hello.
Could someone provide references about mapping algorithms used in Data Integrator for automatic mappings creation. I saw that it could compare source and target attribute data types and names to generate mappings. Do any advanced algorithms (some normalization applied to source and target attribute names (e.g., removing vowels), vocabulary analysis (e.g. using synonyms) ) used by DI to generate mappings automatically?

The only automatic mapping algorithm is the name comparison. No other mechanisms exist, nor can they be plugged in (in the current 10.1.3.5 version of the product).

    Hi,
    I am a newbie to Oracle Data Integrator as well. You should have a look here first; http://www.business-intelligence-quotient.com/?p=379
    Try to play around with ODI and then come back if you have specific questions. You should better move to this ODI-forum; Data Integrator

  • Defunct objects in Data Integrator

    Hi,
    I am getting an error in Data Integrator Designer that says that objects are DEFUNCT, this can be for example Data flow in a Job or a target table in a data flow

    I am still able to execute those Data flows but unable to modify the target options, if I add the same target again in the data flow I am able to work with the target table, but then when I validate and safe the target as become defunct. Can anyone tell me the reason for this error?

    Hi Hector,
    Please ensure that in your Payment Terms code, no such special character has been used that are reserved by XML.This may cause conflict with the XML format and may lead to this issue.
    Moreover, for analysis, you may provide with the list of common Payment Terms across your Intercompany participating companies.

  • How to setup mail client in Data Integrator 11.7 to make use of mail_to()

    How to setup mail client in Data Integrator 11.7 to make use of mail_to() function.
    I am using mail_to() function in one of my job to know the status of source file. If source file is not ready, our DI job should fail and send mail notification with reason for failure.
    But mail_to() function is not sending any mail. I guess I need to set up email client.
    Any one please help to resolve this issue.
    Thanks
    Phani

    From the DI documentation that comes with the installation:
    To use this function, a mail client must be installed and running on the Job
    Server computer that calls the function. The login account for the mail client
    must have the same user name and password as the Data Integrator service.
    The type of client varies by the operating system:
    u2022 If the Job Server is on a computer running the Windows operating
    system, then the mail client must comply with MAPI (message application
    programming interface). In addition, the mail client must be configured as
    the default mail client. For example, Microsoft Outlook is a MAPI-based
    mail client.
    If the Job Server is on a computer running the UNIX operating system,
    then the mail client must be mailx-compliant.
    So:
    Mail client installed and configured and set as default
    Mail client uses the same credentials as the job server service
    Or use another function: smtp_to();
    If still not working or you are not allowed to use an installed mailclient on your box, then try Blat: http://www.blat.net/

  • Outlook 2013 is showing verifying Data Integrity

    Hi,
    When i try to open the outlook 2013,it is not opening and it is showing verifying Data Integrity.
    Please let us know how to resolve the issue.
    Looking forward for your reply at the earliest
    Regards
    Pradeep.R

    Hi Pradeep,
    What type of email account do you use (POP, IMAP, MAPI or Exchange)?
    Based on my research, this issue can be caused by the following factors:
    Outlook data file (.OST/.PST) corruption issues
    Third party add-ins
    To troubleshoot this issue, I suggest we first try the following steps:
    Try to run Scanpst.exe to repair your Outlook data file and see if it helps. If this is an Exchange account, then you can simply rename the
    .ost file to .ost.old or delete it, this will force Outlook to regenerate a new
    .ost file and download all the messages from the server again.
    Launch Outlook in safe mode and see if issue persists. This will help to determine whether this was caused by any third party add-ins:
    Press Win + R and type "outlook.exe /safe" in the blank box, then press
    Enter.
    Hope this helps.

  • Data Integrator treating VARCHAR like LONG

    Data Integerator 11.7 If I map two or more fields from a source table to a target Oracle table, I get the ORA-01461 error, where it thinks I am dealing with LONG columns, when they are VARCHAR2(1200). It works for just one VARCHAR2(1200).

    I found the solution after hours of testing.
    In order for Data Integrator to recognize the proper INPUT and OUTPUT status of stored procedures on Sybase, the procedures must be defined with no brackets ( ) around the parameters
    Example:
    CREATE PROCEDURE pPublDWHProceedExtract
    @tablenamevc      varchar(30) = 'all',
    @action      varchar(30),
    @schedule      int,
    @offset int = 0,
    @valid      int output
    instead of
    CREATE PROCEDURE pPublDWHProceedExtract (
    @tablenamevc      varchar(30) = 'all',
    @action      varchar(30),
    @schedule      int,
    @offset int = 0,
    @valid      int output)

    Hi Shonti,
    The DI 11.7 installer can be used to upgrade a DI 6.1 local repository (e.g. the upgrade is supported).  This will migrate all jobs and flows.  They will remain intact, however, this is always a major migration effort and should not be taken lightly.  If you do upgrade, please make sure this is a planned effort with rigorous testing and validation.  You should also ensure that you consult the release notes and [supported platforms documentation|https://websmp110.sap-ag.de/~form/sapnet?_SHORTKEY=01100035870000712240&_SCENARIO=01100035870000000202] for the 11.7 package you intend to install.  The DI 11.7 documentation also contains info about how to install and configure the Excel Adapter, and what functionality it provides.

  • How Data Integrator supports multiple character sets in a single ETL transaction

    <p>When using Data Integrator (DI) to process a mix of multi-byte and single-byte data, it is recommended that you use UTF-8 for the job server codepage. You can, however, use different codepages for the individual datastores.</p><p>Imagine this situation : Great Big Company Inc. wants to create a global customer database. To do this, Great Big Company Inc. must read from a database of US customers, and a database of Korean customers. Great Big Company Inc. then wants to load both sets of customers into a single database.</p><p>Can DI manage these requirements? Of course. The codepage is the thing.</p>

    I've never seen this used the way you are using it. In my experience the only way to do this would be to execute a single SQL statement that returns multiple result sets - you are trying to append two SQL statements.
    You could define an in-line procedure wrapping your two select statements, or you could define a stored procedure to do the same thing. Then (either way) use CallableStatement to execute the call to the procedure.

  • Foreign key Mapping based on Data - in SQL Developer Data modeler

    Team
    Do SQL Developer Data modeler supports Foreign Key mapping based on the Data in the Schema rather defined at the DDL ? For e.g if we implement a Objects Relation ship mapping in Data base, we don't define Foreign keys at table creation.
    Toad does this feature through "AUTOMATIC FOREIGN KEYS MAPPING IN TOAD DATA MODELER" more info at (http://toadworld.com/Blogs/tabid/67/EntryId/905/Automatic-Foreign-Keys-Mapping-in-Toad-Data-Modeler.aspx)
    any one know how to implement through some scripts also helps me
    Regards
    Raj

    If you have table PKs defined and the candidate columns match those PK columns, then you can use the Discover Foreign Keys utility. Right mouse over the relational model name (node) in the left browser. It is about half way down the menu. I did a blog post about it last week on kentgraziano.com.

  • Oracle Data Integrator 11.1.1.5 Work Schema - List of Privileges

    Hi All,
    Oracle Data Integrator 11.1.1.5.
    Extracting data from Oracle DB for Oracle EBS 12.1.3.
    Customer created read-only schema (XXAPPS) to extract the data from EBS.
    For ODI Work schema we now created one schema 'XBOL_ODI_TEMP' on the source DB. We are now looking for appropriate privileges that needs to be granted to XXAPPS and 'XBOL_ODI_TEMP' so that we won’t face the any error messageS related to permissions when we run ODI scenario?
    We are now facing the error message : ODI-1227: Task SrcSet0 (Loading) fails on the source ORACLE connection VTB_ORACLE_EBS_1213.
    Caused By: java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist.
    Similar previliges can be granted to the work schema on target.
    Venkat

    i think it would be fine with only one schema(user) created at the source system which has got read access on the tables of the EBS DB. Now to resolve this error, assuming XXAPPS user is the one used,
    in the topology --> data server(for EBS) --> physical schema the EBS schema name could be selected for Schema and XXAPPS as the work schema(for all ODI work related objects e.g. CDC)
    Also, in the Data server the user XXAPPS needs to be used which has read access to EBS tables.
    Now everytime ODI generates a query it will access a table lets say DUMMY as ,<EBS Schema>.DUMMY thus the reference is made.
    Alternatively, you can create synonyms for EBS tables in XXAPPS schema.
