Kathy,
Sure your not using the Sql*Server gateway product? I can't find any =
licensing info on Oracle.com about it & our sales rep didn't understand =
what we were talking about either (not a first I should also mention). =
Also as is noted on Oracle.com these types of products are not sold by =
the CPU, but for the computer as a whole.
BTW: That's cheap. Try Partitioning at $10K per cpu or RAC at $20K per.

Watch / How you are using it. =20
We are using Heterogeneous services with a driver from data direct to =
access
some data in our sql server and oracle in 3 different oracle views.
$2,000/cpu so this is not cheap
Personally, I am not happy doing this... I wanted the deveopers to have =
the
app open a separate ODBC connection and get the data
So when sql server goes down, we need to restart the app anyway. Once =
the
application is up again, if someone accesses the view via an old =
connection=20
to the Oracle database, we get ora-28500 errors, some solaris page =
swapping
and the database load goes up for a bit.
If Sql Server hangs and someone accesses the Oracle/Sql Server view - =
guess
what? Yep=20
Plus as an added bonus we got a new error last week [LEMRIST()+384]
[SIGSEGV] [ADDRESS NOT MAPPED TO OBJECT] [12] ORA-07445
not sure what happened with sql server this time (I think it hung), =
Oracle
datatbase when to a crawl, the machine was swapping and we pegged memory =
for
acouple of minutes. I logged a tar with Oracle and all they could =
suggest
was to increase our swap space. This seemed unrealistic since we =
already
have
2G of swap space and normally don't even use 1/4 of this space on a very
busy day.
Let me know what you find out from Golden Gate and if there connection =
works
better.
Good Luck,

Subject: Heterogeneous Replication
L&G,
We are looking at replicating data from Oracle (8.1.7.0 and 9.2.0.4) to
MS-SQL (2K). I would like to know if anyone has done this using
heterogeneous services and if yes would you please get me started at =
least
with the right links to RTFM. Anything additional will be gravy. We are =
also
looking at Golden Gate solutions (for Oracle to MS-SQL) and I'd =
appreciate a
feed-back, if anyone has had any experience with it.=20
Kind Regards,
