DB2<-->netware<-->oracle

I am looking for a solution to the following problem. On the IBM ES9000 DB2 exists. On the Sun SS1000 there is an oracle data base.
>From the PC on the netware side, my customer wants to write
a 4GL application that talks to both the Sun and DB2. Are there any packages that will allow this? For DB2, I would guess LU6.2 would be used.

Thanks in advance.
