Purpose:<\/h3>\n
\n
\n

Retrieve variables from remote nodes and update local CyFlex variables based on a specification file.<\/p>\n<\/dd>\n<\/dl>\n

Enter:<\/h3>\n
\n
\n

snode_link<\/strong>\u00a0 <filename> [name=task_name] [host=hostname] \u00a0[direction=push|pull] &<\/p>\n<\/dd>\n<\/dl>\n

Where:<\/h3>\n
\n
\n\n\n\n<\/colgroup>\n\n\n\n\n\n
\n

filename<\/p>\n<\/td>\n

\n

Specify the pathname of the specification file that contains a list of local and remote CyFlex variables.<\/p>\n<\/td>\n<\/tr>\n

\n

name<\/p>\n<\/td>\n

\n

Optional. Specify the name to register this task with the operating system. \u00a0The default value is “snode_link”.\u00a0<\/p>\n<\/td>\n<\/tr>\n

\n

host<\/p>\n<\/td>\n

\n

Optional. Specify the IP address or hostname of the remote computer used for specifications involving CMD_LINE.\u00a0\u00a0<\/p>\n<\/td>\n<\/tr>\n

\n

direction<\/p>\n<\/td>\n

\n

Optional. Specify ‘push’ or ‘pull’ to indicate the direction of data transfer. \u00a0The default is to \u2018pull\u2019 data from the remote node.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/dd>\n<\/dl>\n

Example:<\/h3>\n
\n
\n

snode_link\u00a0<\/strong>\u00a0\/specs\/node_link_specs.123 \u00a0&
\nThe above starts \u2018snode_link\u2019 on the local node accessing the CyFlex variables specified in the file node_link_specs.123. \u00a0The task name of “snode_link” is registered with the operating system.<\/p>\n

snode_link<\/strong>\u00a0 node_link.settings \u00a0direction=push \u00a0host=xyznode27 \u00a0&
\nThe above starts \u2018snode_link\u2019 on the local node and move data to xyznode27. \u00a0The local computer must be able to resolve the host name into an IP address.<\/p>\n<\/dd>\n<\/dl>\n

Notes:<\/h3>\n
\n
\n

A maximum of 1200 variables may be specified in each file, transferred in blocks of up to 6 variables per block and up to 200 blocks. It is required that all nodes have the connection server (connsrvr) running and that remote nodes run sm_server. This program is typically spawned via the go script, and multiple instances can be used for different nodes.<\/p>\n

This program is normally spawned via the go script. Multiple copies may be spawned if links to different nodes using separate specification files are desired.<\/p>\n

The following is an example specification file linking to more than one node.<\/p>\n

Standard CyFlex intervals may be used beginning with CyFlex version 6.3.<\/p>\n<\/dd>\n<\/dl>\n
