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.

Defining variables


We will now look into defining variables in the following sections.

Variable location and scope

Variables are defined in the Designer navigator either under a given project or as global objects.

Project variables can only be used in the project where they are defined. Global variables can be used in any project. We will see later in this chapter that variables can be used to make models more dynamic. When using variables in models, we have to be very careful and make sure that if we use project variables, the model is not used in another project where the variable is not defined. If a model is shared across projects, and if that model must be dynamic, then make sure to use global variables in the model.

Note

The notion of a global variable only means that variables can be used in different projects. It does not necessarily mean that the same value will be shared by all projects. The value of a variable is local to a project and is based on how and when the value is set. From...
