IBM does not provide an IBM.Data.DB2.dll assembly for Linux. IBM only provides IBM.Data.DB2.dll for Windows. This goes the same with other proprietary database management systems out there, such as, Oracle and Sybase. These companies only support Microsoft .net framework - they do not even acknowledge Mono.
Mono provides a homemade IBM.Data.DB2.dll assembly, but it is not maintained. I cannot see what is available on Linux right now, but I can see what the Mono Windows installer installs. Mono only installs IBM.Data.DB2.dll for the 1.0 profile. The assembly is not built for the 2.0 profile. I suggest using System.Data.Odbc instead. Novell does maintain System.Data.Odbc, and IBM does have an ODBC driver for DB2 on Linux. --- On Thu, 2/12/09, Carlos Ruiz Diaz <carlos.ruizd...@gmail.com> wrote: > From: Carlos Ruiz Diaz <carlos.ruizd...@gmail.com> > Subject: Re: [Mono-dev] IBM.Data.DB2.DB2Exception: Unable to allocate > statement handle > To: "Bartolomeo Nicolotti" <bnicolo...@siapcn.it> > Cc: mono-devel-list@lists.ximian.com > Date: Thursday, February 12, 2009, 10:46 AM > After failing trying to connect with the native driver I > switched to > unixODBC and it works fine for me.
