PRIMARY PROCESS Command for TCP6SAM

The SCF PRIMARY PROCESS in TCP6SAM lets you switch connections to a backup

processor. The information maintained about the Guardian sockets is checkpointed to

the backup when the backup is started. This lets the TCP6SAM process switch the

roles of the primary and backup processes.

Command Syntax

OUT file-spec

causes any SCF output generated for this command to be directed to the specified

file.

PROCESS TCP6SAM-name

is the name of the TCP6SAM process. If you omit the object name, SCF uses the

assumed object name. For information about the ASSUME command, see the

SCF Reference Manual for G-Series RVUs or the SCF Reference Manual for H-

Series RVUs.

CPU cpu-number

is the number of the processor of the backup process. This attribute is required.

Examples

To cause the TCP6SAM primary process to become the backup process (the attribute

CPU 2 identifies the processor where the former backup process resided):

SCF> PRIMARY PROCESS $ZTC1, CPU 2

Considerations

If the specified processor is not the processor of the backup process, the command is

rejected.

START Command

The START command initiates the operation of TCP6MONs, SUBNETs and routes for

the NonStop TCP/IPv6 subsystem. When the subsystem has successfully completed

processing this command, the specified object is placed in the STARTED summary

state. You can start a SUBNET or a route, but not a process. If a process is not started,

it is undefined.

This is a sensitive command.
