The server definition file (SDF) is an initialization (.ini) file that contains the technical information that the QMF for Windows and QMF for WebSphere applications need to connect users to database servers. The QMF for Windows administrator is responsible for creating, configuring and maintaining the SDF for the QMF for Windows and QMF for WebSphere end users.
You must supply at least one SDF for the QMF for Windows and QMF for WebSphere applications to use. You can choose to use the default SDF or create a new SDF.
