Linked Server from SQL Server 2012 to AIX DB2 via SSL - sql-server-2012

Question

I need to create a linked server from SQL Server 2012 to a IBM DB2 (9.x) on AIX. It is a mandatory requirement to create the connection with SSL.
I was trying to use "Microsoft® OLEDB Provider for DB2 v4.0 for Microsoft® SQL Server® 2012" but I was not able to connect to DB2 by the Data Access Tool from MS OLEDB.
Later I installed the IBM DB2 client tools and GSKIT and with this I can connect to DB2 via SSL. With the installation also came the connection provider "IBM OLE DB Provider for DB2". The problem is that I can't create the linked server.
I always get the error message
Cannot create an instance of OLEDB Provider "IBMDADB2.DB2COPY1" for linked Sever "mydb2" (Microsoft SQL Server , Error 7302)
In some discussions was mentioned to use a specific provider string, but in this case the field of the provider string is greyed out.
I just have the options for Product name and Data Source. Is the Data Source == the DB Name of the Connection form the IBM BD2 Client tools? What should I use as Data Source?

Answer 1

Okay i could solve the problem and want to share the solution.
The mentioned provider IBMDADB2.DB2COPY1 comes from the installation of the IBM DB2 Client tools.
In Server Objects --> Linked Servers --> right click new server you can choose the provider. Using the "IBM OLE DB Provider for DB2 - DB2COPY1" which has access to the configured connection including the SSL Keys, the field Data Source is greyed out.
The key to successfully create a linked server to a DB2 is not the guy but the script. There you can use also provider string information even it is greyed out in the GUI.
EXEC master.dbo.sp_addlinkedserver #server = N'MyLinkedServer', #srvproduct=N'IBMDADB2',
#provider=N'IBMDADB2', #provstr= N'HOSTNAME=hosturl;Port=12345;
DATABASE=DBinDB2Client;UID=ItsMe;Pwd=secret;Security=SSL;', #datasrc=N'DBinDB2Client'
Et voila, as you can see the linked server will be created successfully and can acceess the DB2 Database. The issue is solved.

edit:
the linked server can only! used by it's creator. if other users want to access the server, they'll get this error:
Cannot create an instance of OLE DB provider "MSDADASQL" for linked server "MyDB2"
there is a tutorial how to give the permission to other users:

after you walk through the tutorial, you also need to reboot.
