Oracle Data Integrator Architecture

The following series will be a high level look at the pieces, components, and basic workings of ODI, which should help any reader comprehend some of the finer pieces of this data integration and ELT tool.

The GUI graphical modules are listed above.

The four ODI GUIs – Designer, Operator, Topology Manager and Security Manager, are based on Java. They can be installed on any platform that supports Java Virtual Machine 1.4, including Windows, Linux, HP-UX, Solaris, pSeries and so on.

Designer is the GUI for defining metadata, and rules for transformation and data quality. It uses these to generate scenarios for production, and is where all project development takes place. It is the core module for developers and metadata administrators.

Operator is used to manage and monitor ODI in production. It is designed for production operators and shows the execution logs with errors counts, the number of rows processed, execution statistics etc. At design time, developers use Operator for debugging purposes.

Topology Manager manages the physical and logical architecture of the infrastructure. Servers, schemas and agents are registered here in the ODI Master Repository. This module is usually used by the administrators of the infrastructure.

Security Manager manages users and their privileges in ODI. It can be used to give profiles and users access rights to ODI objects and features. This module is usually used by security administrators.

All ODI modules store their information in the centralized ODI repository.

ODI KM Adding Order by Option

You can add Order by statement to queries by editing KM.I have edited IKM SQL Control Append to provide Order by. 1) Add an option to KM named USE_ORDER_BY, its type is Checkbox and default value is False. This option determines you want an order by statement at your query. 2)Add second option to KM named ORDER_BY, type is Text. You will get order by values to your query by this option. 3) Editing Insert New Rows detail of KM. Adding below three line code after having clause. That's it! <% if (odiRef.getOption("USE_ORDER_ BY").equals("1")) { %> ORDER BY <%=odiRef.getOption("ORDER_BY" )%> <%} %> If USE_ORDER_BY option is not used, empty value of ORDER_BY option get error. And executions of KM appears as such below; At this execution, I checked the KM to not get errors if ORDER_BY option value is null. There is no prove of ORDER BY I'm glad. Second execution to get Ord

Creating Yellow Interface in ODI

Hello everyone! In Oracle data integrator (ODI), an interface is an object which populates one datastore, called the target , with data coming from one or more other datastores, known as sources . The fields of the source datastore are linked to those in the target datastore using the concept of Mapping . Temporary interfaces used in ODI are popularly known as Yellow Interfaces . It is because ODI generates a yellow icon at the time of creation of a yellow interface as opposed to the blue icon of a regular interface. The advantage of using a yellow interface is to avoid the creation of Models each time you need to use it in an interface. Since they are temporary, they are not a part of the data model and hence don’t need to be in the Model. So let’s begin and start creating our yellow interface! Pre-requisites : Oracle 10g Express Edition with *SQL Plus, Oracle Data Integrator 11g. Open *SQL Plus and create a new table Sales in Oracle. You can use any existing ta

Running Count in Talend Open Studio

Most Talend components keep a count of the records processed using variables like NB_LINE or NB_LINE_OK. But these are only available after all processing is completed. Define your own counter variable to keep a running count for use in a tMap. Variables like tFilterRow.NB_LINE or tAccessOutput.NB_LINE_INSERTED can be used to report the number of affected lines after a subjob's processing. However, it may be of use to get the current line index for use in a tMap. The index variables used to form NB_LINE aren't available during processing; they're only written out the globalMap at the end of processing. In this example, staging records are loaded from Excel to Access. The order in which the Excel records are read is preserved in a database column called DISPLAY_SEQ_NB. Note that there is an auto-increment column used for record ID in the Access table. This could be used to infer a loading order, but this job uses a separate column to keep the ID as a meaningless surr
