Hi,
I think I've the same problem:
s...@lxpc54:~/src/test$ gmcs -r:/usr/lib/mono/1.0/IBM.Data.DB2.dll
-r:/usr/lib/mono/2.0/System.Data.dll helloDB2.cs
s...@lxpc54:~/src/test$ mono helloDB2.exe
You must tell me your name!
s...@lxpc54:~/src/test$ mono helloDB2.exe bart
Hello, bart
Unhandled Exception: System.DllNotFoundException: db2_36

IBM.Data.DB2.DB2CLIWrapper/StaticWrapper36:SQLAllocHandle

Then I've tried to edit /etc/mono/config:
sudo vim /etc/mono/config
<dllmap dll="oci" target="libclntsh.so" os="!windows"/>
<dllmap dll="db2cli" target="libdb2_36.so" os="!windows"/>
adding this line (not target="libdb2.so", because the mono loader adds the
.so extension itself):
<dllmap dll="db2_36" target="libdb2" os="!windows"/>
and it Loaded the right library, as you can see from below, but then I
realized that the ADO.net namespace we use is:
IBM.Data.DB2.iSeries
so we have to use unixODBC, because this namespace is not implemented in
Mono, is it?
For the connection and the data could you please tell me which namespace are
you using in you application?
Many thanks
Best regards
