I am working on migrating a NET application that accesses an Informix database so that it can run in a Docker container. I have done a POC and when I run it on my local machine it works correctly. But when I want to run the same application inside a container, an exception is thrown:
Unhandled Exception: System.DllNotFoundException: Unable to load DLL 'db2app.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E) at IBM.Data.DB2.UnsafeNativeMethods.DB232.SQLFreeConnAttribsADONET(DB2SQLGetConnAttribsADONETParams& pParam) at IBM.Data.DB2.ConnSettingsFromXmlConfig.Dispose(Boolean disposing) at IBM.Data.DB2.ConnSettingsFromXmlConfig.Dispose() at IBM.Data.DB2.DB2ConnPool.ReplaceConnectionStringParms(DB2Connection connection, String szValue, DB2ConnSettings& pSettings, DB2ConnSettingsInternal& pSettingsInternal, Boolean bAttach, Boolean pushDownStrAppended) at IBM.Data.DB2.DB2Connection.set_ConnectionString(String value) at IBM.Data.DB2.DB2Connection..ctor(String connectionString) at ConsoleInformix.Program.Main(String args) in
The container is based on the image: microsoft/aspnet:4.7.2-windowsservercore-1803
The main application to migrate is a Web API project (.NET Framework 4.7.2)
Examining NuGet packages for IBM.DataDB2 warns: "NOTICE - This package requires the IBM DB2 client software to be installed locally and available on your %PATH% environment variable"
But I have not managed to solve how to perform unattended or silent installation of the IBM client in the container. Can anybody help?
