IBM DB2 manual Prerequisites, Deployment procedure for a .NET application

Remark: For those familiar with Java and J2EE, there are a lot of similarities between the J2EE and .NET. The execution environment in J2EE is the Java Virtual Machine, which correspond to the Common Language Runtime in

.NET. The .NET specifications correspond to the J2EE specifications. .NET supports a large variety of programming languages, but C# (pronounced C-sharp) is considered to be the pendant of Java in the .NET framework.

Prerequisites

Before you can access DB2 from your .NET application, these prerequisites must be in place:

￿.NET Framework Version 2.0 or higher

At the time of writing this booki, the latest version of the .NET Framework is 3.5. Usually, you should download and use the latest version.

￿IBM Data Server Driver

If either IBM Data Server Client or IBM Data Server Runtime Client is presented, installing IBM Data Server Drive is not required. Otherwise, we require IBM Data Server Driver for ODBC, CLI, and .NET

Note: DB2 supports also the old .NET Framework version 1.1. However, it is not recommended to use this old version.

Installation procedure

First of all, ensure that the .NET Framework is installed on your Windows environment. You can check this by opening the “Add or Remove Programs” dialog from the Windows Control Center. If installed, the framework will be listed in the program list. If the framework is not presented, download the msi-install file for .NET Framework version 3.5 from the Microsoft Download Center:

Next, install the IBM Data Server Driver as described in 4.1.2, “IBM Data Server Driver for ODBC, CLI, and .NET, and IBM Data Server Driver for ODBC and CLI” on page 143.

Deployment procedure for a .NET application

We assume that the .NET framework is already installed on the target system, that is, we do not cover this topic in this deployment example. We concentrate on the deployment of the application, IBM Data Server Driver for ODBC, CLI, and the .NET. However, if installing the .NET framework is required, this step can easily be added to the install script, using a silent install of the msi installation file for the framework.
