Select business object lazy parsing mode

For large objects, lazy parsing XML data can provide significant performance improvements over eager parsing.

The default mode for parsing business objects is eager mode, however selecting lazy parsing mode in IBM Integration Designer can provide better performance for BPEL applications. It is worth performing performance measurements to determine which mode provides the best performance for your applications. For best performance, try to avoid having modules that frequently interact with each other using different parsing modes. If mixed mode parsing is unavoidable, invocation from an eager parsing module to a lazy parsing module is more efficient than the other way around.

The following characteristics suggest that lazy parsing will provide better performance.

The following characteristics suggest that eager parsing mode will provide better performance.

Implications for error handing

Changing the parsing mode has implications for error handling. If the XML byte stream being parsed is ill-formed, parsing exceptions occur.

To handle ill-formed XML for either parsing mode properly, use one of the following options:
