FTP Collection Agent Transaction Behavior
- Former user (Deleted)
This section includes information about the FTP collection agent Input/Output data processing. For information about the general behavior, see Administration and Management.
Input/Output Data
Input Data
The agent transmits commands that change the state of the file currently processed
Command | Description |
|---|---|
Begin Batch | Transmitted before the first byte of each collected file is fed into a workflow. |
End Batch | Transmitted after the last byte of each collected file has been fed into the system. |
Output Data
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 the workflow level (set in the workflow properties) 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. 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 block processed (32 kB), 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 data in the subsequent block). |
