Hi,

it may help u.

With the release of patchset 10.1.3.3 for Oracle SOA Suite 10.1.3, some cool new features have been introduced that I would like to bring to your attention. Besides the long-awaited error-policy framework, we now also get the option to de-batch large XML files when polling them from a file or FTP location. Debatching has been an option for the File and FTP adapters for some time now, but was always restricted to native (flat) files (typically record-based layouts). Large XML files have always been a challenge to BPEL, because internally XML is loaded in a DOM tree, which takes a considerable amount of memory compared to the original size of the document in its text form.

<!~~[if !supportEmptyParas]~~> <!~~[endif]~~>

What does de-batching do?

Debatching polls for incoming files, and when it finds a file and starts reading it, it doesn't start a single new instance of a BPEL process and delivers the file contents, but instead it chops up the file in "batches" of configurable size (typically 1), and starts a new instance for each batch. So for a file of 1000 records (lines) and a batch size of 1, you will end up with 1000 new instances. There is no guarantee that these 1000 instances will be executed in order of the records in the original file, mind you. These instances will be processed by the pool of engine threads just like any other active instance. For XML, as part of the patch install instructions for the 10.1.3.3 patchset, you install a "stream-based" XML parser called STaX, which is well-known in the Java community. Instead of reading the whole file into main memory, the STaX parser just "browses" like a lexical scanner through the XML file and does not build large trees of objects in memory.
