Thank you for the pipeline statistics - that is helpful to explain. I see that you already added the Tail snap in, but it looks like you added it after the Oracle Execute 3 snap, which I believe you are using to generate your file output including the header. You should add the Tail immediately following the Oracle Insert snap.
Here is why: The pipeline is reading from Oracle and writing to “NBRJOBS_new.csv” file, then reading a file and performing Oracle Inserts (one document at a time). Keep in mind that the Oracle Insert snap passes the update information for EACH document to the output view… so 490 document in is 490 document out of that snap. This means that the Oracle - Execute Update SWEADTE snap is being executed 490 times (once for each input document), and I don’t believe this is what you want.
By adding the Tail snap before that Oracle - Execute Update SWEADTE snap, you are limiting the number of documents going into that snap to 1, so the snap will execute only once.
This is an exercise in understanding the behavior of each snap in the pipeline. The documentation of the snaps should help with that.
