Heterogeneous Services

Hi all -

I am in the "conception" stage of setting up Heterogeneous Services (HS) from a 9.2.0.8 Linux database to a MSSQL 2000 (v 8.00.2039) database. I need to pull data from MSSQL into Oracle. I've been OTN'ing, RTFM'ing, metalink'ing and google'ing but am still fuzzy about exactly what I need to do. Figure 7-1 in
http://download.oracle.com/docs/cd/B10501_01/server.920/a96544/gencon.ht m#1656 is the closest I can find to what I am trying to accomplish. This also seems close to what I am trying to do: http://www.dba-oracle.com/t_heterogeneous_database_connections_sql_serve r.htm. The query will initiate from the Oracle side.

A few questions:

1. Do I need to install/run an Oracle listener on the MSSQL box?
2. Do I need to get a 3rd party ODBC driver for my Oracle/Linux server? If so, any vendor/freeware/shareware recommendations are appreciated. I've been poking around the DataDirect.com site so far.
3. I see many references to the hsodbc "program". Is this really a program/executable or just the way to tell the listener to use the HS that are configured in the Oracle database?
4. Last, any pointers/links to docs are appreciated.

Thanks,
-joe
