Informatica to Datastage Migration Checklist
Posted: Fri Nov 19, 2010 12:21 am
Hi Friends,
We are working on Informatica to Datastage Migration project. One of the job which we have developed is giving issue. All the mappings and transformations are same as Informatica mappings and logics. But the record count in the target differs. For Example, Informatica is loading 2 records whereas Datastage is loading 5 records in the target.
We found one difference in Informatica behavior and Datastage behavior.
For example : In Datastage, INNER JOIN will process all the multiple matched records whereas in Informatica INNER JOIN will process only one of the multiple matched records.
Table A :
Emp_Name Emp_No Arun 257816 Arun 257644
Arun 269812
Table B :
Emp_Name
Arun
Join Condition : A.Emp_Name = B.Emp_Name
Datastage Join Stage populates all the 3 records but Informatica Join Stage populate only one of those 3 records.
Do you know any other architectural behavior differences between Informatica & Datastage ?
