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.

• Configure a communications network in a TCP/IP network
  This topic provides a high-level overview of the steps you take to set up a TCP/IP network.

• Security requirements for DDM
  You can prevent intentional and unintentional access to the data resources of a system by the DDM user.

• DDM file requirements
  Before remote files can be accessed by an iSeries server, DDM files must be created on the source server.

• Program modification requirements for DDM
  Remote files can be accessed by iSeries application programs written in the HLL and control language.
