How can you use an Oracle sequences in Informatica? You have an Informatica sequence generator transformation also. Which one is better to use?
Sequence generator may create issue in case of partitioning. The duplicate keys get generated in sequence generator. We cannot have cannot have multiple table feeder processes.
Then, we can use either Oracle database sequences or Lookup / Expression transformation to create sequence numbers. Although, Oracle sequences are better as it
will also handle the case where there are other sources feeding the Target under consideration other than ETL. Yes, there is slight hit in performance, but it's minor in most situations.
