FTP Collection Agent Transaction Behavior(3.0)

Transaction Behavior

Emits

The agent emits commands that changes the state of the file currently processed.

Command

Description

Begin Batch

Emitted before the first byte of each collected file is fed into a workflow.

End Batch

Emitted after the last byte of each collected file has been fed into the system.

Retrieves

Command

Description

Cancel Batch

If a Cancel Batch message is received, the agent sends the batch to DataVeracity.

Note!

If the Cancel Batch behavior defined on 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 DataVeracity 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).
