A File Listener mode is available to process TABLE or MODIFY requests on collections of data files.

This mode allows you to set up a listener directory where files can be dropped. The server monitors this directory and processes files in real time, according to the rules set by the parameters in the Access File.

You can use wildcards to designate file names and extensions, providing flexible descriptions of the collections to be processed.

File processing options include:

• Pickup strategy (immediate, trigger).
• Discard strategy (delete, archive, keep).
• Polling interval.
• Timeout interval (if no new files appear in the listener directory).
• Maximum number of files to be processed in a request.

There is also an option for processing remote sources using an FTP server.

The Adapter for Flat Files can read Unicode UTF-16 files as data sources.

A DATASET parameter or FILEDEF for a flat file can use an asterisk (*) as a wildcard to represent multiple files. To identify which file (of many) a record comes from, you can add a field with an ALIAS of INSTANCE to the Master File. When used in a SELECT, TABLE, or MODIFY procedure, that field will have the name of the specific file.
