Central directory server start option list

A central directory server is a network node that builds and maintains a directory of resources throughout the network. This directory reduces the number of network broadcast searches to, at most, one per resource. VTAM® network nodes and end nodes register their resources with a central directory server. For additional information about VTAM central directory servers, see the z/OS Communications Server: SNA Network Implementation Guide.

In the sample start option list that follows, the start option CDSERVR=YES means that this node will be a central directory server. Only network nodes can be central directory servers.

NETID, SSCPID, and SSCPNAME are required start options. HOSTPU is not required; however, it is recommended if you are using NetView®. The CONFIG start option identifies a unique name of the configuration list to be activated when VTAM starts.
