We are trying to use Oracle Service Bus for a large-volume (> 1GB) file-based interfaces with external partners. Have anyone implemented such integration scenario? Any constraints / limitations of OSB/ Weblogic / File Adapters? What sort of FTP mechanism can we use with it?
SFTP transport supports processing of large messages. When you configure a proxy service, you can enable content streaming and specify whether large messages must be buffered in memory or in a disk file.
Attachment option allow the proxy service store MIME attachment content to a disk file and then process the data in a streaming fashion without buffering the attachment contents in memory. This enables the proxy service to process large attachments robustly and efficiently.
