This section includes information about the SFTP collection agent transaction behavior. For information about the general transaction behavior, see Transactions in 3.1.11 Workflow Monitor.
Emits
The agent emits commands that changes the state of the file currently processed.
Command | Description |
|---|---|
Begin Batch | Will be emitted just before the first byte of each collected file is fed into a workflow. |
End Batch | Will be emitted just after the last byte of each collected file has been fed into the system. |
Retrieves
The agent retrieves commands from other agents and, based on them, generates a state change of the file currently processed.
Command | Description |
|---|---|
Cancel Batch | If a Cancel Batch message is received, the agent sends the batch to ECS. Note! If the Cancel Batch behavior defined on workflow level is configured to abort the workflow, the agent will never receive the last Cancel Batch message. In this situation, ECS will not be involved, and the file will not be moved, however left at its current place. APL code where Hint End Batch is followed by a Cancel Batch will always result in workflow abort. Make sure to design the APL code to first evaluate the Cancel Batch criteria to avoid this sort of behavior. |
Hint End Batch | If a Hint End Batch message is received, the collector splits the batch at the end of the current processed block (as received from the server), provided that no UDR is split. If the block end occurs within a UDR, the batch will be split at the end of the preceding UDR. After a batch split, the collector emits an End Batch Message, followed by a Begin Batch message (provided that there is more data in the subsequent block). |
