Hello Experts ,

We have SAP ECC powered on the database oracle (12G), we attend to move into Hana .

The problem that we have some oracle databases witch connected to our oracle database (SAP ECC), using the DB LINK.

The DB link will be still supported in HANA.

According to your experience , what is the best approach to keep our connection to theses external databases?

Thank you for your help.
