Is the question about a one-time migration, i.e. moving an application that is currently accessing DB2 to access Oracle, in which case the Oracle Migration Workbench is probably a good first step? Or is the question about regularly migrating data from DB2 to Oracle, i.e. replication, in which case Heterogeneous Connectivity would be a good approach?

If the question is the former-- a complete move from one database to another-- be aware that you will probably have to invest a significant amount of time after the Migration Workbench moves the code to Oracle to get equivalent performance from Oracle. In general, applications are going to do things that work really well in one database but that aren't appropriate in another database. Migration Workbench will do a relatively dumb conversion of the code, which is fine for 60% of the cases, but you'll have to manually fix up the other 40%.

I have to migrate a DB2 database to Oracle and was wondering if any of you have ever done it and have some hints for me.

Thanks in advance
