Getting Started with Oracle Data Integrator 11g: A Hands-On Tutorial

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.

Managing execution errors


Execution errors can be categorized in a number of ways, but for the sake of simplicity we'll use a simple matrix to divide between design-time and run-time in one dimension, and anticipated versus unexpected in the other, to distinguish between the tools and approaches that are most likely to be used in each circumstance:

Handling anticipated errors

If we can anticipate that an error might occur, such as a database server being offline or unreachable, then we should be able to specify what should happen in the event of such an error. We should build our systems (ODI packages, scenarios, or load plans) to cope with this type of error.

The mechanism to use for this in ODI is the error (KO—or "not OK") path in the ODI Package editor. By using this technique we can send alerting e-mails, perform automated investigation or mitigation activities, and so on.

Tip

An important point to remember is that if our post-error processing completes successfully (for example, the alert...
