The file writer offers several conditions for output file creation. During debatching, the file reader, upon restart, proceeds from where it left off in the previous run, thereby avoiding duplicate messages. When a file contains multiple messages, you can select to publish messages in a specific number of batches. The file reader guarantees once and once-only delivery. This feature can be utilized for performance tuning of the file and FTP adapters. The file reader can split the contents of a file and publish it in batches, instead of as a single message. After processing the file, the files can be deleted, moved to a directory, or left as is. The file reader supports polling conventions and offers several postprocessing options. The outbound file and FTP adapters have parameters for the outbound directory in which to write the file and the file naming convention to use.
The inbound file and FTP adapters have parameters for the inbound directory where the input file appears and the frequency with which to poll the directory.
This operation is known as a JCA outbound interaction.įor the inbound and outbound directions, the file and FTP adapters use a set of configuration parameters. This functionality of the file and FTP adapters is referred to as the file write operation and the component that provides this functionality as the file writer. This operation is known as a Java Connector Architecture (JCA) inbound interaction.įor outbound files sent from Oracle BPEL Process Manager, the file and FTP adapters perform the following operations:įormat the XML contents as specified at design time This functionality of the file and FTP adapters is referred to as the file read operation and the component that provides this function as the file reader. Read and translate the file contents based on the translation logic defined at design time Based on the direction, the file and FTP adapters perform a different set of tasks.įor inbound files sent to Oracle BPEL Process Manager, the file and FTP adapters perform the following operations: The file and FTP adapters exchange files in the inbound and outbound directions. The FTP adapter also supports the use of secure FTP on Solaris.

The FTP adapter supports Solaris and Windows FTP servers.
The native data can be simple (just a flat structure) or complex (with parent-child relationships). The translator enables the file and FTP adapters to convert native data in various formats to XML, and vice versa. The opaque option handles binary data such as JPGs and GIFs whose structure cannot be captured in an XSD or data you do not want to have translated. The file and FTP adapters can also treat file contents as an opaque object and pass the contents in their original format (without performing translation). The file and FTP adapters can read and write the following file formats and use the adapter translator component at both design time and run time: The file and FTP adapters enable you to configure your BPEL process to interact with local and remote file system directories.
