DB2 10.5 for Linux, UNIX, and Windows

Upgrading ADO.NET applications

Upgrading your existing ADO.NET applications to DB2® Version 10.5 involves managing the changes between DB2 Version 10.5 and previous releases that impact these applications and verifying that these applications function as expected.

Before you begin

You do not have to upgrade ADO.NET applications that use the OLE DB .NET Data Provider or the ODBC .NET Data Provider to run with DB2 Version 10.5. However, upgrading these applications to the Data Server Provider for .NET can be beneficial for the following reasons:
  • The Data Server Provider for .NET has a far more extensive set of APIs than the OLE DB and ODBC .NET data providers.
  • Access to the DB2 database development productivity tools integrated with Visual Studio.
  • Use of the Data Server Provider for .NET can bring significant performance improvements.
  • Ensure that you have access to a DB2 Version 10.5 server, including instances and databases. The DB2 server can be part of a testing environment.
  • Ensure that a supported version of the Microsoft .NET Framework software is installed on the DB2 database client computer.

  • Perform the previous steps in the Upgrading database applications task.

Procedure

To upgrade your ADO.NET applications to DB2 Version 10.5:

  1. Review the support for the Data Server Provider for .NET and how to program your applications to use the Data Server Provider for .NET and determine what changes to make on your ADO.NET applications.
  2. Rebuild your ADO.NET applications to use the Data Server Provider for .NET.

What to do next

After upgrading your ADO.NET applications, perform the remaining steps in the Upgrading database applications task.
