IIRC, HS has its own init.ora parameter file and you need to set hs_nls_lang there.

Before shifting this topic to gateways/HS discussion...Back to the original question - I WAS using heterogeneous services and got a problem moving Unicode data from SQL Server to Oracle. Any help?

I think you need odbc for this, so for windows no problem, for unix you could look at the datadirect drivers (from Merrant ?). Used it years ago, pretty straighforward. regards, Jan On Fri, Nov 7, 2008 at 7:11 PM, Goulet, Richard <Richard.Goulet@xxxxxxxxxxx <mailto:Richard.Goulet@xxxxxxxxxxx>> wrote: Michael,If that's what your developers want then your only option,that I know of, is Oracle's transparent gateway to Sql*Server.

It doesn't require using ODBC. The Oracle connection is via Java connector, and the SQL Server connection is via open source SQL Server connector (jTDS) If you do try it, use version 1.2. The new 1.5 version of SQL Developer doesn't work for the SQL Server -> Oracle migration. I just used it this week, and have a question in on OTN for the 1.5 version.
