In Informatica, leveraging external loaders is a common practice for efficiently loading target files into various databases such as IBM DB2, Oracle, Sybase IQ, and Teradata. However, before initiating the use of external loaders, certain rules and best practices must be adhered to ensure smooth and optimized data loading processes. Understanding these rules and implementing them correctly is essential for maximizing performance and maintaining data integrity
Before initiating the load process, it is crucial to disable constraints that are built into the tables receiving the data. This ensures that data can be loaded without encountering integrity constraint violations, thereby preventing loading failures and ensuring seamless data transfer.
To preserve high performance in the database during the load process, consider increasing commit intervals and turning off database logging. However, it's important to note that turning off logging may impact the ability to perform database recovery on failed sessions. Therefore, carefully evaluate the trade-offs between performance and recovery requirements based on specific project needs
Ensuring consistency in code pages is essential for seamless data transfer between external flat files and target databases. All external database servers must utilize the same code page as the target flat file code page to prevent data encoding issues. The integration services in Informatica generate control files and target flat files using the specified code page, facilitating accurate data transfer.
When the integration service is configured to run on a grid environment, it's imperative to configure the external loader connection as a resource on the node where the external loader is available. This ensures that the integration service can seamlessly access and utilize the external loader for efficient data loading operations, leveraging the resources available in the grid environment.
