Product user profile error

We are developing systems and have reached the point where we need a training database separate from the production database. I created the database, added the tablespaces, imported the data from the production and can connect just fine from sqlplus and sqldba. If I try to connect via SQLNET I get the following warning errors:

WARNING: product user profile information not loaded! Error in disabling roles in product user profile.

After this, the product seems to run just fine on the server. PC client apps (Powerbuilder) are hosed, though.

Any sage advice would be welcome.
TIA
