Db transaction (commit and rollback) in datastage?

This is not a good practice, in DW ETL process, you need to design you job as re-entrance able rather than transaction, transaction is expensive, you just need to fix the issue and restart the job, in most cases ,you can't get issues fixed without human interfere.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
