Overview of this book

Oracle Data Integrator (ODI) is Oracle's strategic data integration platform for high-speed data transformation and movement between different systems. From high-volume, SOA-enabled data services, to trickle operations ñ ODI is a cutting-edge platform that offers heterogeneous connectivity, enterprise-level deployment, and strong administrative, diagnostic, and management capabilities. "Getting Started with Oracle Data Integrator 11g: A Hands-On Tutorial" provides you with everything you to get up and running with Oracle Data Integrator, and more! Following an example scenario, the book covers essential information about the ODI architecture and using ODI across different databases (Oracle, Microsoft SQL Server and MySQL), and file types such as XML, before covering Orchestrating Data Integration Workflows, Error Management, Operational Management and Monitoring, and beyond. "Getting Started with Oracle Data Integrator 11g: A Hands-On Tutorial" begins by describing the Oracle Data Integrator architecture and teaching you to install the product following best practices. You'll then be introduced to some of the key concepts of ODI such as the Knowledge Modules. Later topics include moving and transforming data from sources to targets including the Oracle Database, Microsoft SQL Server, MySQL, Flat files, and XML files, each with illustrated hands-on examples for the different technologies. Your learning experience will be made all the more rich with chapters introducing, explaining and leveraging additional ODI functionality such as variables, reusable procedures, temporary indexes and more. Finally ODI's workflow and task orchestration capabilities are explained before introducing you to Error Management with ODI's built-in 'error hospital' and 'error recycling' capabilities for non-compliant data, not to mention tackling ODI Studio, ODI Console and Enterprise Manager Fusion Middleware Control.

Using variables to alter workflows


We will now learn how variables can be used in Packages and Load Plans.

Packages

Variables can be used in Packages for multiple reasons. As we have already seen, variables are assigned different Types or actions when they are added to a Package. We have already discussed the ability to Declare, Refresh or Set variables. Another type is to Evaluate a variable.

The evaluation of a variable will allow you to choose how you want to proceed—the expression that is evaluated will return True or False. To continue with the next step of your Package, you will simply use what would otherwise be the Ok (which is represented by a green arrow in the ODI Studio) and Ko (which is represented by a red arrow in the ODI Studio) arrows—True being the green arrow and False being the red one. Variables can be compared to literals or to other variables. When comparing variables to one another, pay attention to the variable datatypes, and do not forget to prefix the variable name...
