How to Add TCPMAN as a Generic Process to the System
Configuration Database
Although you should not need to add $ZZTCP as a generic process more than once,
HP recommends that you create a command file for the procedure as a safeguard to
allow you to resume the exact configuration of $ZZTCP as a generic process.
To add a generic process to the system configuration database for $ZZTCP, create a
command file containing the following commands like the one shown in Example 4-2
(substitute your own values for those parameters indicated in italics). See the SCF
Reference Manual for the Kernel Subsystem for complete information about adding a
generic process.
Because you have set STARTMODE to SYSTEM, whenever the system is loaded or
whenever the TCPMAN is stopped, the persistence manager restarts the generic
TCPMAN process (#ZZTCP) and all the most recently configured SUBNET, ROUTE,
ENTRY, and MON objects. See How to Stop the Generic Process for TCPMAN if you
don’t want the persistence manager to restart #ZZTCP every time you stop the
$ZZTCP using a TACL STOP command.
How to Stop the Generic Process for TCPMAN
If the TCPMAN 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 Parallel
Library TCP/IP subsystem, you will receive an error. If you have also set
AUTORESTART greater than zero, the process is persistent and the persistence
manager will restart the process if the process stops due to a processor failure or
abend. To stop $ZZTCP if it is a persistent, generic process, issue the following SCF
command:
->ABORT $ZZKRN.#ZZTCP
Note. You can start the TCPMAN process from a RUN command rather than through the
persistence manager and TCPMAN will restore the configuration of the subordinate objects
from the system configuration database. Remember, that TCPMAN does not start any
TCPSAM processes; you must start TCPSAM processes manually whether you are using the
persistence manager or the RUN TCPMAN command.
