In-Depth Information
The final part of this screen in the adapter wizard asks if the file contains a single
message or many messages. This is confusing because when the screen refers to
messages, it really means records.
XML files,
It is worth remembering that a well formed XML document can only have
a single root element, and hence an XML input file will normally have
only a single input record. In the case of very large XML files, it is possible
to have the file adapter batch the file up into multiple messages, in which
case the root element is replicated in each message, and the second level
elements are treated as records. This behavior is requested by setting the
streaming option.
By default, a message will contain a single record from the file. Records will be
defined in the next step of the wizard. If the file causes a BPEL process to be started,
then a 1000 record file would result in 1000 BPEL processes being initiated. To
improve efficiency, records can be batched, and the
Publish Messages in Batches
of
attribute controls the maximum number of records in a message.
