How to Add TCPMAN as a Generic Process to the
System Configuration Database
The ABORT PROCESS command to $ZZKRN.#ZZTCP stops $ZZTCP and causes the
persistence manager not to restart it until a system reload. To restart TCPMAN, issue
the following SCF command:
->START PROCESS $ZZKRN.#ZZTCP
If you don’t 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 4-2, Command File for Adding TCPMAN as a Generic
Process, on page 4-5):
•
Change STARTMODE to MANUAL. In this case, you must always issue an SCF
START $ZZKRN.#ZZTCP to restart TCPMAN.
•
Delete the generic process ($ZZKRN.#ZZTCP). In this case, TCPMAN is no longer
a generic process and the persistence manager no longer starts it automatically
upon system reload.
•
Change STARTMODE to DISABLED. In this case, the generic process
($ZZKRN.#ZZTCP) remains in the system configuration database but is not started
by the persistence manager. In addition, you cannot manually start the generic
process ($ZZKRN.#ZZTCP) until the STARTMODE is changed back to SYSTEM or
MANUAL.
If you ABORT the process $ZZTCP by using the SCF command to the Parallel Library
TCP/IP subsystem (ABORT PROCESS $ZZTCP instead of ABORT PROCESS
$ZZKRN.#ZZTCP) and specify the SUB ALL in the ABORT command, only the
TCPMAN process is restarted when you issue a RUN command or when the
persistence manager restarts the process. The SUB ALL specification in the ABORT
command deletes the MON objects from the configuration database. If you have
issued the ABORT PROCESS $ZZTCP, SUB ALL command and want to restart the
subsystem, issue a START MON * command to the NonStop TCP/IP subsystem. This
action starts all subordinate objects with the configuration attributes that are stored in
the system-configuration database.
For information about managing generic processes, see SCF Reference Manual for
the Kernel Subsystem.
The following example shows how to stop the generic process #ZZTCP:
-> ABORT PROCESS $ZZKRN.#ZZTCP
To manually restart TCPMAN after aborting it under the NonStop Kernel subsystem,
issue the following command:
->START PROCESS $ZZKRN.#ZZTCP
Caution. Before stopping the TCPMAN ($ZZKRN.#ZZTCP), stop all applications that are
using the Parallel Library TCP/IP environment. (See Stopping Parallel Library TCP/IP as a
Generic Process on page 1-29 for procedures for checking what applications are using Parallel
Library TCP/IP.)
