We need to develop some solution for our company to comunicate our db2 - as/400 based systems to new Oracle dbs.

We saw there are products like:
-DB2 Information Integration from IBM
-Access Manager for AS/400 from Oracle

to accomplish that, but they are very expensive...
Somebody knows a lower cost option, some third party product to do the same thing?

Any comment will be greatly appreciated, thank you in advance.
