Oracle 7 Transparent Gateway for UDB8

We are currently migrating our mainframe to z/os. we now have a hard time starting our oracle transparent gateway in the new mainframe. We only upgraded our mainframe and DB2 but not oracle.

Can oracle transparent gateway for oracle 7 be installed in Z/OS? can it connect to UDB8? or we really need to upgrade our oracle also? :confused:

You need to upgrade. :p

why can't it be done? is there a way to somehow change the parameters of our z/os so it will run? what are the incompatibilities?can you provide me with links on where to read to support my decision on upgrading the oracle..

:o

thanks!
