Define Remote Node Information

You define a network map entry for each remote node that communicates with the local node. The network map defines the following components:
  • Remote node definition—Information about remote Connect:Direct® nodes that the local node communicates with, including retry parameters, maximum session connections, and network information.
  • Communications mode—Information relating to session characteristics for a protocol, such as TCP/IP or UDT mode information. A communications mode can be associated with one or more communications paths or remote node definitions.
  • Communications path—Transport and protocol information about the available communications paths and their attributes. The protocol information includes protocol type, such as TCP/IP, and specific protocol type information, such as the name of the TCP mode for TCP/IP protocols. Each communications path definition specifies a default communications mode.

    Each remote node definition can be related optionally to one communications mode and can be related to multiple communications paths, allowing multiple communications paths and modes to be available for use when communicating with the named remote node. These communications paths and modes can be shared with other remote nodes and are not specific to one remote node definition. Communications paths are used when establishing sessions with a remote Connect:Direct node. Connect:Direct tries each communications path named, in the order in which it is listed, until either a session is established or all paths have been tried. You must designate at least one path.

When defining, modifying, or deleting network map entries, be aware of the dependencies among the three components and the manner in which they refer to each other. For example, before you name a communications mode in your communications path definition, the communications mode must exist.
