Subject: Heterogeneous Services

Hi all -

I am in the "conception" stage of setting up Heterogeneous Services (HS)
from a 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
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:
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 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.
