From where can i download Database gateway for 10.2.0.4 (windows 64 Bit)

Question

Hi,
I have joined a company which has a legacy 10.2.0.4 RAC on windows. They did not have anyone to manage and now i am in.
I recommended them to upgrade to the certified version, but they do not want it as it will be decommissioned.
Now we have to connect to sql server from this database. I want to install gateway for that but i cannot find it for download.
Please let me know from where can i download.
And also i saw some discussions, where in it says it is possible to do this with out gateway?
Regards

I would put the emphasis on the first part of your statement:
here the gateway would be installed on a RAC cluster.
Installing on the cluster, and the further decision to install on multiple nodes of the cluster, is a local decision.  There is nothing about the gateway itself that requires this.
So you have n-node installations (as it does not ake sense to have the gateway just on one node which might be down). When you install DG4MSQL (not DG4ODBC) on 2 machines then you need two licenses as the gateway is licensed on a machine basis and it does not matter to how many MS SQL Server machines you're going to connect to.

I would agree with the obvious.  IF (and I doubly-emphasize the "IF") one determined they wanted to install on multiple nodes of a cluster, they would have to consider the licensing implications.
However, my point is that there is no inherent need to install the gateway on a cluster in the first place, and so no need to incur that licensing issue.

1.1 Gateway Installation Configurations
You can install Oracle Database Gateway in either of the following configurations:
On the same computer as an existing Oracle database but in a different Oracle home.
On a system with no Oracle database.
On the same computer as the Oracle database and in the same Oracle home directory. Note that in this case, the Oracle database and the gateway must be at the same release level.
And if anyone is tempted to say "well, that's for *nix installations", the Windows installation guide says the same thing:
From Oracle® Database Gateway Installation and Configuration Guide 11g Release 2 (11.2) for Microsoft Windows E12061-06 (http://docs.oracle.com/cd/E11882_01/gateways.112/e12061/overview.htm#OTGIW100)

Which is exactly what we opted for at my shop.  Since the gateway is a system-wide resource, used to connect ANY of our oracle databases to ANY of our MSSQL databases, no one server made any more sense than any other.  I wanted to have to manage only a single gateway and not have to worry about which gateway was on which machine to service which databases.
