config_fabrics - Data Stream Architecture

Purpose

Beginning with DSA release 16.10.01, the config_fabrics command defines the routing data path between TPA nodes and media servers using a parameter file. For best performance when using network fabric, make sure dsc.properties has validate.fabric=on.

Network fabric is not supported for repository backup and restore.

Syntax

config_fabrics -n|-name -f|-file FILE

Example

config_fabrics -f file1.xml

Parameters

n|name fabric_name

[Optional] Name of the fabric configuration.

f|file filename

The full path and name of the file containing the necessary configuration parameters.

u|user_authentication User

Required when security management is enabled. Supplies the command with the Viewpoint user, and triggers a password prompt for authentication.

Usage Notes

A fabric configuration can be defined for one Teradata system. The information is saved into the repository and can be edited if new media servers or nodes are added.

The target group must define one media server that belongs to the fabric.

If a fabric is defined, job submission skips the logical net mask and selects the existing fabric when defining job data paths.
