Prepare to use DDM

There are several requirements that must be met for DDM to be used properly.

Notes:

Before determining which files should be accessed using DDM, review Performance considerations for DDM.
Programming requirements and considerations for control language (CL) commands and data description specifications (DDS) are covered in Using CL and DDS with DDM and Operating considerations for DDM.

Communications requirements for DDM in an APPC network
Each iSeries™ server in a DDM network that is not using OptiConnect must have these communications requirements.
