I am migrating a very large and complex database from DB2 to Oracle 11g. Can someone suggest any tools / processes to do this very quickly. My database is about 500 GB and it cannot have downtime much more than about 4-6 hours maybe a little more but not much.
Source: Linux SuSE 11 64 Bits - DB2 9.7 Target: Linux Redhat 64 Bits - Oracle 11G
Thanks for any help..
