When planning a DB2-based Domino application, remember that end users do not need their own DB2 connectivity. The Domino server fulfills this responsibility.
Creating a DB2-hosted Domino database results in a small NSF file that is created on the file system of the Domino server in its data directory. This file is typically smaller than a megabyte (often only a few kilobytes). DB2-backed Domino servers can replicate and cluster with traditional NSF-based Domino servers, so that both environments can co-exist if necessary. This can be particularly useful when testing Domino DB2 integration with existing Domino data.
The Domino and DB2 servers have the following possible relationships:
The DB2 UDB server is installed locally on the Domino server.
The DB2 UDB server is installed on a remote host accessible to the Domino server.
Testing environments typically leverage a DB2 UDB server that is installed locally on the machine where Domino is installed. The obvious advantage...
