This is my first post on here.
I'm having trouble creating a linked server in SSMS because Oracle is not listed as a provider.
However, in BIDS the Oracle provider is visible. I can connect to my database just fine.
It appears that BIDS is 64 bit and SSMS is 32 bit so I downloaded 32 bit Oracle ODAC but the provider is still not visible.
I'm at my wits end here so any help would be greatly appreciated.
Thanks.
Make sure you have a full oracle client installed on the server, with Oracle ODAC 11.2.0.3 you may have to select "Oracle Provider for OLE DB" when installing (i.e. not ticked by default I think.)

I am trying to install Oracle Developer Tools for Visual Studio 2015 so that I can connect to a remote 11g database from SSRS/Visual Studio Projects in general, from my dev machine. When I go to the downloads page, I see this:
So I went to Visual Studio to determine whether I already had ODT, and found this:
However, I don't think I installed this ODP, and it just came with the Visual Studio installation. Is there a way to uninstall this provider, or am I OK to just install the new ODT over top? Lastly, as I did more research for this post I became a little more unsure: does ODAC include ODP.net?
Thanks.
Microsoft OLE DB Provider for Oracle and .NET Framework Data Provider for Oracle are providers from Microsoft, i.e. they are part of your Windows installation.
Indeed, they are deprecated from many years, however there is no reason to remove them. They are just two little DLL's.
It is no problem to install Oracle Provider for OLE DB and Oracle Data Provider for .NET (ODP.NET) from Oracle, the drivers from Oracle and the drivers from Microsoft do not interfere with each other.
Yes, ODAC (Oracle Data Access Components) is a collection of various drivers, ODP.NET, OLE DB, ODBC and a few more.
Just a note, unless you use the ODP.NET Managed Driver all drivers mentioned above require an Oracle Client installation, typically an Oracle Instant Client. I think the Oracle Instant Client is also included in the ODAC package.
Maybe have a look at this post to get a little overview: How to connect to Oracle 11 database from . net
I have Oracle 11 installed. I recently installed Crystal Reports 2013. However, I do not see Oracle Server listed when I try to create a new connection. I am not sure why. Please suggest me.
Thanks,

I needed to have Oracle Client for Crystal Report to connect to the Oracle database. Once I installed a 32 bit oracle client, I was able to see Oracle Server as a option in the Connections.
I wanted to let you all know so that if somebody is stuck like me, they can benefit from this answer.
Thanks again!
I have a new dev machine, and I need to support legacy SSIS packages. The new machine is Windows 8 64 bit with a SSD primary drive (C:) and a regular HDD for data (D:). On it, I have installed BIDS 2008 R2 (and all the tricks to get it to work with TFS2010), as well as VS2010, ODAC 32 bit and 64 bit (I think??), Oracle Client (SQLDeveloper).
I can get the following to connect just fine to an Oracle database:
VS2010 with MSDAORA
VS2010 with ODAC
VS2010 with ADO.NET
Test connection using .udl file with Oracle OLE DB Provider (MS provider does not show up as an option here)
SQLDeveloper (Oracle's Client Tool)
What I CAN'T seem to do is get BIDS 2008 R2 to connect to Oracle using ANY method (MSDAORA, ADO.NET, ODAC).
The problem seems isolated to my machine, I can otherwise open, view, validate, connect and run these packages on other machines with no issues.
I have tried the following:
Ensured any/all TNSNAMES files are correct and identical (taking working copies from other machines, and let's not forget, this works fine in VS2010)
Created ORACLE_HOME and TNS_ADMIN Environment Variables and pointed them to various directories within D:\app\username\product\11.2.0
Checked registry manually to make sure no other references to ORACLE except for the entries in HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE
Unistalled/Reinstalled SQL Server 2008 R2 components
Every "solution" offered in every thread in every search I have tried
Thrown chicken bones and offered sacrifices to pagan deities
After each attempt at a fix, I still get the following error when trying to Preview a SQL Command in the Data Flow:
An OLE DB record is available. Source: "Microsoft OLE DB Provider for Oracle" Hresult: 0x80004005 Description: "Error while trying to retrieve text for error ORA-01019"
Yes, I know I need to drop MSDAORA in favor of ODAC, and if ODAC worked in BIDS 2008 R2 I would certainly do it. However, I can't get anything to connect to Oracle there (even though, as mentioned above, it connects fine in various other tools)
I have two "client_n" directories in D:\app\username\product\11.2.0. As mentioned, I have tried pointing my environment variables to various paths inside. It seems like the correct path for ORACLE_HOME should be just D:\app\username\product\11.2.0, correct?
Has anyone had any luck getting BIDS 2008 R2 to connect to Oracle while on WINDOWS 8 with VS2010 also installed? It seems to me like it's a simple Oracle connection issue, I just don't know enough about Oracle to troubleshoot.
Any other ideas to try?
BIDS is x32 (even on an x64 machine), so you will need to install the Oracle Client x32 edition, Full Install.
We were able to get it to work, though I believe that we installed too much software. (I have not been able to test it with only the ODAC drivers.)
Install the Oracle Client 32 & 64-bit drivers.
Install the Oracle ODAC 32 & 64-bit drivers.
In BIDS use the native Oracle connection, and not the Microsoft driver.
I installed
ODAC 11.2 Release 3 and Oracle Developer Tools for Visual Studio (11.2.0.2.1)
from http://www.oracle.com/technetwork/topics/dotnet/utilsoft-086879.html
but i still do not see Oracle driver in the ODBC Manager... please help.
i checked the ODBC Drivers in the Registry, and only found SQL there... maybe i downloaded the wrong thing? someone please point me in the right direction.
Call "c:\windows\SysWOW64\odbcad32.exe" from the start/run box or from the command prompt, so
the drivers are more likely to appear. I´ve been through similar problems with Oracle Instant Client (basic and ODBC) 32-bit driver not appearing at the ODBC Admin Window. I was able to configure a Data Source to Oracle 11g Express by calling "c:\windows\SysWOW64\odbcad32.exe" this way.
Regards.
I can't access the page you referenced to read about it, but to install the Oracle ODBC driver you can install the Oracle Instant Client. This page gives some good instructions on how to do it. Once the instant client is installed, the Oracle ODBC driver should show in the ODBC Manager. Note that you do not need a full client install to use the ODBC driver.
Run cmd with elevated privileges to install odbc_install.exe.
I'm working on a Sql Server Reporting Services solution that queries across both a Sql Server data source and an Oracle 10g data source. My dev box is Windows 7 64bit with Sql Server 2008R2 and I'm hosting IIS7 and SSRS on that system for development; using VS.NET for designing the reports.
I have been having errors when running the report where SSRS complains about loading the 32 bit Oracle client in a 64bit process. There a number of threads out there about how to solve that. The thing is, they all come down to making sure you have the 64bit Oracle, client which I do. The weird chain of events I have goes like this:
Create initial Oracle datasource and wire up report (it works)
Edit Oracle datasource connection (it stops working with BadImageFormatException 32bit/64bit error message)
uninstall and reinstall Oracle client (it works)
Edit Oracle connection again (it stops working with BadImageFormatException 32bit/64bit error message)
So short of reinstalling the client every time I change the connection string I am at a complete loss. Has anybody seen this sort of behavior? And if so what the heck am I doing wrong?

This is the second time I configure a similar server, and the second time I spend hours figuring this one out. If for nobody else, I am writing this for the future me. This is for a Windows Server 2012 R2 64bit, 8GB RAM, 300+GB HDD, Intel Xeon CPU E5620 # 2.40GHz, that is running Microsoft SQL Server Reporting Services 2012 64bit and IIS 7.0 with web applications that use the Oracle Client 32bit connection System.Data.OracleClient
Install the 64bit client
Change the name of the Oracle inventory directory # "C:\Program Files\Oracle" to "C:\Program Files\Oracle64"
Restart computer and test for connection from SSRS to Oracle
Install the 32bit client and specify a different location for its home directory
Restart computer and test connection from SSRS to Oracle and from Web Applications to Oracle
I hope this helps my future self and others :)
You need to install 64 bit Oracle Client. Beware, i had bad experience on having both oracle 32 bit and 64 bit client. I ended up uninstalling 64 bit oracle client and trying to figure out installing SSRS in 32 bit mode on 64bit win7.
