Configuration 3: Startup Files for Two Hosts Using
an X25AM-Based Connection
Command Description
ADD DEFINE =TCPIP^HOST^FILE,
FILE MJHOSTS
sets the ADD DEFINE =TCPIP^HOST^FILE.
Whenever a TCP/IP process must convert
from a host name to an IP address, the
TCP/IP process either uses the DNS or a
HOSTS file like MJHOSTS. When the ADD
DEFINE =T=TCPIP^HOST^FILE is set, the
TCP/IP process uses the file as indicated.
This sample configuration does not provide
sample HOSTS files. For sample HOSTS files,
see The HOSTS File
on page 3-11.
TCPIP /NAME $ZTC1, NOWAIT,
CPU 1/2
starts a TCP/IP process (this particular
command assigns the process name $ZTC1).
CPU 1 causes the TCP/IP process to run as a
NonStop process pair, with the primary
process in CPU 1 and the backup process in
CPU 2.
ADD DEFINE
=TCPIP^PROCESS^NAME, FILE
$ZTC1
sets the ADD DEFINE
=TCPIP^PROCESS^NAME to the process
name $ZTC1.
Whenever a TCP/IP process is started using a
process name other than the default ($ZTC0),
you must set ADD DEFINE prior to running
any TCP/IP application (for example,
LISTNER or TELSERV). Each application
reads the ADD DEFINE
=TCPIP^PROCESS^NAME to determine the
process name to communicate with. If this
ADD DEFINE is not set, LISTNER and
TELSERV processes try to communicate with
$ZTC0. $ZTC0 may be the wrong process or it
may not even exist.
SCF /IN TCPSUBU1/
invokes SCF to run the commands in the file
TCPSUBU1; this file contains the commands
to add the necessary SUBNET and ROUTE
objects to $ZTC1.
