I have installed the db2 drivers from the ibm enterprise connect package. I am able to connect to the db2 datasource (system dsn) when I open visual studio in an admin mode and open the integration package. But I get an sqlstate 58031 when I open visual studio in a non admin mode. What am I missing?
Thanks
I have got it working now. Needed to add the user to the db2users group and also gave the user full access over the db2 directory under programData. (At least that is what I think fixed it)

I need to pull data from an Access .accdb database and put it into a SQL Server table. I am unable to create a connection to the Access database from an SSIS package.
Visual Studio 2010 Pro - development tool.
SQL Server Management Studio 2012 - database tool.
Windows 10 Enterprise – OS on development PC.
Office 365, 64-bit – productivity suite on development PC.
Several articles state to use the “Microsoft Office 12.0 Access Database Engine OLE DB Provider” to create a connection to the Access database. I currently do not have this data provider.
The 2010 version of Visual Studio is a 32-bit product, and therefore needs a 32-bit connection to Access. I have tried to install the “Microsoft Access Database Engine 2010 Redistributable”, but it will not install because I already have the 64-bit version of Access installed.
Any thoughts on how to install the 32-bit Access data provider – in the presence of a 64-bit version of Access.
To install Microsoft Access database engine 32-bit alongside 64-bit installation, you should install it using the passive mode.
Passive mode installation steps
Open the Command Prompt by typing cmd in the Windows search box under the Start menu and selecting cmd.exe
Type the file path and file name of the 32-bit Access Database Engine 2010 install file, followed by a space and /passive (this runs the installation without showing any error messages).
Open the Registry Editor by typing regedit in the Windows search box under the Start menu and selecting regedit.exe
Delete or rename the mso.dll registry value in the following registry key:
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Common\FilesPaths"

I am trying to install ODAC 18c Release 1 (18.3.0.0.0) and when I click on the Setup.exe it shows the black screen(command prompt ) and there after nothing is coming. The universal Installer is not at all loading.
Currently I am using Windows 10 Enterprise edition ,
VS 2015 , 2017 Professional editions are installed.
My Machine is 64 bit
Other than the above I have installed ODTwithODAC1120320_32bit also in my system.
No idea why the installer is crashing.
I could see a prerequisite like
Access to an Oracle Database Server (Oracle 11g Release 2 or later)
is needed for the instillation in installation guide. In fact my oracle database server is located in some other place and we are accessing that from my location , so I need only client for accessing that. I am not sure what they meant by
Access to an Oracle Database Server (Oracle 11g Release 2 or later)
Do I need to install the Oracle database 11g+ ?? Do the crashing issue is because of some other reasons ?
Can someone help me to resolve this ?
Methods I have tried so far :
Open the install folder directly and click on the oui.exe directly
Disconnect internet and try to install
Run the installation exe in elevated rights mode
Kill the java.exe from task manager and try to install
None of the above methods are working.
And finally I found the reason.
I didn't have a _JAVA_OPTIONS in the system variables. I have added that and run the installer as run as administrator.
The variable value should be -Xmx512M
Newbi to oracle and its versions and .NET providers, but did some investigation.
I'm trying to add Oracle connection to the visual studio server Explorer (before setting up the Entity Framework 6 for oracle).
System preferences:
Windows 10 enterprise - 64 bit operating system
Visual Studio 2015
Oracle Data Access Components (ODAC) which includes Oracle developer Tools for Visual Studio: ODAC12C - 12.2.0.1 - it is suitable to 64 bit !
The DB is located in a remote machine and I can see the DB objects using the Oracle SQL developer. It uses the TNSNames file to locate the DBs.
when trying to "add connection" in the visual studio server explorer:
Select Data Source: Oracle DataBase
Data Provider:.NET framework data provider for Oracle.
It claims that:
"This provider is deprecated and should not be used. Instead download
Oracle Developer tools for visual studio for comprehensive integration
with Oracle database."
The problem is that the mentioned above reference links to a 32-bit Oracle Data Access Components (ODAC) bundle which includes "Oracle Developer Tools for Visual Studio". The same shXX happens when choosing .NET framework data provider for OLEDB.
Either I don't see the relevant provider in the list or there is a problem.
After inserting Server name, User name and Password in the "Add connection" dialog box, I get this error message:
"Attempt to load Oracle Client libraries threw BadImageFormatException.
This problem will occur when running 64 bit mode with the 32 bit Oracle Client components installed"
What am I doing wrong ?
Is this the way of defining connection string when I have a TNSNames file ?
Microsoft .NET Framework Data Provider for Oracle is different to Microsoft OLE DB Provider for Oracle which is different to Oracle Data Access (which can be Oracle Data Provider for .NET or Oracle Data Provider for .NET Managed Driver or Oracle Provider for OLE DB, depending on which one you installed), see How to connect to Oracle 11 database from . net
Visual Studio 2015 is 32-bit, when you like to connect to an Oracle database directly from Visual Studio Explorer then you have to download/install the 32-bit version of ODAC - and also install 32-bit Oracle Client.
In case you like to use also 64-bit Oracle Client and drivers follow this instruction: BadImageFormatException. This will occur when running in 64 bit mode with the 32 bit Oracle client components installed
I have installed Oracle Developer Tools for Visual Studio 2017. I am now finally able to create my database classes within VS2017 without switching back to VS2015.
After the installation I am getting the following error message upon opening an old project and also when creating a new Oracle database connection (in a new project) in Visual Studio 2017:
oracle data provider for .net has been installed without a
machine-wide configuration
(...) Also found anoher version in the GAC that might be incompatible, please uninstall it and restart VS2017
(Poorly translated the german message to english, but you get the point)
Problem is: The version in my GAC is the newer version needed for VS2017. I definitly do not want to uninstall that, but the non machine wide data provider from earlier. I can't find anything about how to do that. Do you guys have any ideas?
Please forgive me if my attempt itself is not smart at all => I haven't installed Oracle Tools for VS before and ran into loads of problems doing so earlier.
Just for the record: I have been trying to google for a solution, but I did not manage to find one. If you got the key-Keywords let me know-
I installed this Version from 6th july 2017
Oracle Developer Tools for Visual Studio 2017 (12.2.0.1.0)
This download includes:
Oracle Developer Tools for Visual Studio 12.2.0.1.0 Oracle Data
Provider for .NET 4, Managed Driver 12.2.0.1.0 Oracle Providers for
ASP.NET 4 12.2.0.1.0
I did a lot of installing of the Oracle tools before getting it to work. Not an expert, but I found many installations of my "Oracle Home". In order to uninstall versions that I did not want, I used the Oracle Universal Installer. This is found (for Windows 7) in "Start Menu -> All Programs -> Oracle-Ora Client-your specific client -> Oracle Installation Products.
Run the installer and choose which oracle home you want to uninstall. You should be able to determine which one is the one that you want to uninstall by looking at Registry Keys, HKLM->Software->Oracle. Also HKLM->SOFTWARE->Wow6432Node->ORACLE. There may be others, search for Oracle keys.
SO figure out which oracle home you want to uninstall and use the Universal Installer to remove it. This should preserve the installation that you want and remove the one you don't. I'm not an expert, just offering what has worked for me.
In Visual Studio 2017, when I create new connection (using the wizard), there is a hard-coded path to a TNSNAMES.ORA file, that can't be changed through the wizard. It is set up through the above-mentioned registry keys. This is key to mapping your Data Source to an actual database. Hope this is helpful.
I know that while connecting .net to oracle, you can attach dll's and run the program, can we do the same with db2? if so, then what are the dlls and where can i find them? i've tried connecting ibm.data.db2.dll (downloaded from net) but vs is giving a error saying it may not be valid build for vs.
any idea?
You need to install at least the IBM Data Server Runtime client appropriate for your DB2 version and, optionally, Visual Studio plug-ins from http://www-01.ibm.com/support/docview.wss?uid=swg27016878
