Data-streaming Operation

Each of the OTDs in the Batch Adapter exposes stream adapter nodes that enable any OTD to participate in data-streaming transfers. The nodes are named InputStreamAdapter and OutputStreamAdapter. You can associate the stream adapters by using the drag-and-drop features of the eGate Enterprise Designer.

The InputStreamAdapter (highlighted) and OutputStreamAdapter nodes in the OTD are used for data streaming. This feature operates as follows:

• Stream-adapter consumers: The FTP and the record-processing OTDs can only consume stream adapters. Therefore, their stream-adapter nodes are write-only. Their node values can be set (modified).

• Stream-adapter provider: The local file OTD can only provide stream adapters, so its stream-adapter nodes are read-only. Its node value can only be retrieved.

The local file OTD is always the stream provider, and the FTP and record-processing OTDs are the consumers.
