#### Re: New version of IBM Data Server Provider for .NET Core

Is the IBM.Data.DB2.Core 1.2.2.100 package supposed to be compatible with azure?

I had my application working fine locally, but once I deployed to azure I got the "db2app64.dll" could not be loaded 0x8007007E. Which looks like a mismatch in architecture.

And this was after I had installed the "win10-x64" dotnet runtime on the azure instance. (Which is necessary to get a .net core 2.0 x64 app working. https://blogs.msdn.microsoft.com/webdev/2018/01/09/64-bit-asp-net-core-on-azure-app-service/)

I actually got it working by making my own package which is a combination of the IBM.Data.DB2.Core 1.2.2.100 package, and the IBM.Data.DB.Provider 11.1.3030.4 package. Pretty much just including more dll's in the clidriver folder.

But I just wanted to confirm that IBM.Data.DB2.Core was not supposed to work with azure out of the box?

Hi JacobJeske.

This would appear to be the exact issue I am facing at the moment. If you could upload the package that would be great. I am fairly new to using NuGet packages and Azure, so the more details you can provide the better. You will help me look really good in front of the boss if I can get this over theline!

Hi JacobJeske,

Currently IBM.Data.DB2.Core is not supposed to work with azure out of the box. We have it in our plans, but it is not yet fully tested for many of azure scenarios and is not yet certified for azure.

Thanks

Hi JacobJeske.

I am fairly new to using NuGet packages and Azure, so the more details you can provide the better. You will help me look really good in front of the boss if I can get this over theline!

I actually cant post the nuget package here because technically the organization I work for owns the code. BUT I can tell you how to make your own, its not too hard.

1. Download IBM.Data.DB2.Core 1.2.2.100 (https://www.nuget.org/packages/IBM.Data.DB2.Core/1.2.2.100) and IBM. Data. DB. Provider 11.1.3030.4 (https://www.nuget.org/packages/IBM.Data.DB.Provider/11.1.3030.4)
3. Using Nuget Package explorer export the packages to respective directories.
4. Copy all the folders in "\IBM.Data.DB.Provider\build\clidriver" (bin, bnd, cfg, conv, db2, lib, license, msg)
5. Past them into "\IBM.Data.DB2.Core\build\clidriver" and make sure to "replace\over write" the dll's with the same name when prompted.
6. Open up "\IBM.Data.DB2.Core\IBM.Data.DB2.Core.nuspec" in a diff tool like beyond compare, along side with "\IBM.Data.DB.Provider\IBM.Data.DB.Provider.nuspec" (the nuspec file names will have the version numbers in the name, I removed the version and the space for easier packing).
7. All you want to compare is everything in the <files></files> node. Copy over any <file src="..." target="..." /> from the IBM.Data.DB.Provder.nuspec that is not in IBM.Data.DB2.Core.nuspec pertaining to the "\build\clidriver" directory.
8. Save the IBM.Data.DB2.Core.nuspec file.
9. Run command "nuget pack IBM.Data.DB2.Core.nuspec" from the "\IBM.Data.DB2.Core" directory.
10. And boom, the package should work in azure.

Notes:

- If you do change the name of the package, make sure the name in the nuspec file <id></id> is changed to match as well and that you also change the name of the file "\build\IBM.Data.DB2.Core.targets" and its corresponding <file /> node in the nuspec file as well.

- I used the option 2 in this article to get the "win10-x64" runtime installed (https://blogs.msdn.microsoft.com/webdev/2018/01/09/64-bit-asp-net-core-on-azure-app-service/) (web.config method)

Hope that helps, the package is passing all our test for our DB2 application, but as Vishwa said its not tested or certified by IBM or Azure. There is a possibility that some features may be not working because they are out of scope of my organizations test coverage.

Thank you for this, JacobJeske!

Just burned several days trying to get this working on Azure and if not for you, I would still be struggling with it.

So far I'm very disappointed with IBM's implementation. The licensing nonsense already cost us a couple days and still isn't sorted out. Finally we get connected only to find that we can't deploy to Azure :(

EDIT: Spoke too soon. Stitching together the two packages has not resolved our issues :(

JacobJeske,

Any chance you can elaborate on this? I've followed the instructions very carefully but still cannot this to behave once deployed to Azure. The errors I'm getting range from "AccessViolationException" to "ArgumentOutOfRangeException". Both of which (through much, much digging) seem to result from library referencing issues.

Any help would be greatly appreciated!

Are you able to share a stack trace?

Just some basic checks:

- Are you using .Net Core 1 or 2? (I am using .net core 2.0)

- Are you running the project in x64 runtime?

- Make sure you have all the files from "\IBM.Data.DB.Provider\build\clidriver" copied over, and new <file> added to the .nuspec file. (you should have x64 and x86 dll's in there)

- I also have "Allow unsafe code" checked in my database project (where the nuget packages are installed)

- If you are using the "IBM.EntityFramework.Core" nuget package you will also have to re-make that package with your "IBM.Data.DB2.Core" package as its dependency.

- Also make sure the .targets file in the build folder is named the same as the nuget package and its in the <files> node of the nuspec file.

But without more info on the error its hard to know whats really going wrong.

I've gone through the procedure a third time.

• Combined IBM.Data.DB.Provider and IBM.Data.DB2.Core and packed into a new package.
• Updated the IBM.EntityFramework.Core nuget package to reference this new package as a dependency.
• Added the new IBM.EntityFramework.Core package to my solution.
• When I do this, it appears to correctly pull in the dependencies. A "clidriver" folder and its contents are added to the solution as well.
• Locally, I can successfully connect to DB2.
• Publish to azure and try to hit the database using EntityFramework and I get a new error:

Hi,

the required support will be there in our next version. You should be able to use the package as is without having to modify anything in it.

Thanks

Hi Vishwa,

Any update on when the next version is coming? As of today, the problem of the data providers for web apps deployed in Azure is still there.

I'm working on a UWP (Universal Windows Platform) project that uses .NET Core, and I updated to this most recent IBM.Data.DB2.Core version in hopes to fix an error, but it didn't.  My code still crashes.

I also copied the details and that is below.

Can you please share instructions for obtaining a trial license?  We are attempting to use the driver in an Azure Function App to access DB2 on iSeries.  It is throwing an error stating an invalid license file.
