FTP stage
FTP stage destination files must be unique for each job instance.
Note: This design feature of an IBM® InfoSphere® DataStage® job
is applicable for Topology I (batch jobs), Topology II (batch jobs
with an ISD Output stage), and Topology III (jobs with ISD Input
and ISD Output stages).
All job instances will try to update the same file. To avoid these collisions, use the InfoSphere DataStage macro DSJobInvocationId to vary the filename each time a file is written.
