"We are planning to move from a DB2/400 flat-file system to Oracle. We do not have any relations in DB2/400.
I want to extract the Metamodel(total DDL scripts) from DB2/400 and go for data modeling. Initially, I thought Oracle Migration Work Bench (OMWB)would work. Unfortunately, it does not support V5R4 of DB2/400 on the iSeriees. So I can?t use OMWB. ERwin DataModeler is unable to extract the relations directly from the database. Do you know which approach I should take?
