The DDMACC parameter controls how an iSeries™ server, as a target server, handles DDM requests from other servers.
The DDMACC parameter is used on the Change Network Attributes (CHGNETA), Display Network Attributes (DSPNETA), and Retrieve Network Attributes (RTVNETA) commands. The value of this server-level parameter determines whether this iSeries server can accept DDM requests from other servers.
