How do you connect to an Oracle Databse from MSSQL Enterprise Mana


How do you connect to an Oracle Databse from MSSQL Enterprise Mana GKnight

sql server connect: We are trying to connect to an Oracle Server via MSSQL Enterprise Manager so
that we are able to query both the Oracle & SQL Database, can anybody tell me
if this is possible and how to do it??

I have followed the instructions in Q280106 and this does not appear to show
the database in Enterprise Manager, but on the other hand it doesn't say that
it should.

What we are trying to do is make the data in the Oracle Database available to
people using Enterprise Manager to create databases/queries and possibly
Distributable Access Projects.

Sorry I don't actually mean create Oracle databases, it's just so they can
see the data and create views within Enterprise manager to allow them to
query both sets of data and again so that when they create Access Projects we
don't need to install the Oracle Drivers on every client computer (as we find
the microsoft ones don't work very well)

The article mentioned below talks about linking an Oracle server but It
doesn't tell you how to do it, can you give any advice?

Creating a linked server and registering a server in EM are two very
different things. I doubt that EM will work with any dbms other than MS sql
server. At a minimum, you would need to register the oracle server just as
you do a MS server. Creating a linked server is only useful in writing tsql
queries using the 4part naming convention.

Not really. You would go through the process of registering the server just
like you did for the MS servers. I assume that it might first require
establishing connectivity to the oracle first (whatever those requirements
are). As I said, I seriously doubt that EM will work with a non-MS server.

Hello,

what exactly do you want to do? It's possible to query data from almost
every Datasource (even excelsheets), but you need to be a little bit
more specific ;).
Are you going to join data from Oracle and MSSQL?

What you are trying to do is doable. You would create a
linked server to the Oracle instance. You can then create
views that reference tables in the Oracle database.
To create a linked server, you need to first install the
Oracle client on the server. Configure the server as you
would any other Oracle client - make sure you have your
connectivity, tnsnames setup and tested.
After configuring the Oracle client on the server, you set
up the linked server by following step 5 in the article you
mentioned, http://support.microsoft.com/?id=280106
When you create a linked server, you can find it in
Enterprise Manager under Security, Linked Servers. You will
be able to see tables and views - just the object names -
from Enterprise Manager. It's not a GUI where you "interact"
with the data directly. To execute queries against the
linked servers, you can use 4 part names or the Openquery
function. You can find more information on this in books
online under linked servers.
