How to Add TCP6MAN as a Generic Process to the
System Configuration Database
about adding a generic process, see the SCF Reference Manual for the Kernel
Subsystem
As you have set STARTMODE to SYSTEM, whenever the system is loaded or whenever
the TCP6MAN is stopped, the persistence manager restarts the generic TCP6MAN
process (#ZZTCP) and all the most recently configured SUBNET, ROUTE, ENTRY,
and MON objects. If you configure $ZZTCP to be persistent, you need to use the
procedure How to Stop the Generic Process for TCP6MAN to stop the subsystem. If
you do not want the persistence manager to restart #ZZTCP every time you stop it, set
the STARTMODE to MANUAL and remove the AUTORESTART attribute.
How to Stop the Generic Process for TCP6MAN
If the TCP6MAN process has been added as a generic process, you must use the SCF
ABORT command to the NonStop Kernel subsystem to stop it (ABORT PROCESS
$ZZKRN.#ZZTCP). If you issue an SCF STOP or ABORT command under the
NonStop TCP/IPv6 subsystem, you will receive an error. If you have also set
AUTORESTART greater than zero, the process is persistent and the persistence
manager restarts the process if you issue a TACL STOP command or if the process
stops because a processor failure or abend. To stop $ZZTCP if it is a persistent,
generic process, issue this SCF command:
->ABORT PROCESS $ZZKRN.#ZZTCP
The ABORT PROCESS command to $ZZKRN.#ZZTCP stops $ZZTCP and causes the
persistence manager not to restart it until a system reload. To restart TCP6MAN, issue
this SCF command:
->START PROCESS $ZZKRN.#ZZTCP
If you do not want the persistence manager to restart $ZZTCP automatically during a
system reload, you can make one of the three following changes to the generic
process (shown in Example 6-3 on page 6-17):
•
Change STARTMODE to MANUAL. In this case, you must always issue an SCF
START $ZZKRN.#ZZTCP to restart TCP6MAN.
•
Delete the generic process ($ZZKRN.#ZZTCP). In this case, TCP6MAN is no
longer a generic process and the persistence manager no longer starts it
automatically upon system reload.
