cant connect to oracle

Hi guys!

We are trying to connect to oracle db 10gR1 (aix) using progress appserver or just the session itself and we are getting this error:

This module can access ORACLE only through the PROGRESS network (1894)

Failed to connect to ORACLE databse frontier (1451)

here is the connection string that we used:

ftdb=-db orawawa -ld schfrontier -S 12500 -H dev -N TCP -RO -db frontier -U ft1dev@WDEV -P ft1dev -c 270 -Dsrv qt_cache_size,32000

Any ideas why its not letting us connect?

Thanks!
