Configuration Example for the Monolithic Listening
Model
The SCFSBNT File
The SCFSBNT file adds and starts subnets and routes. Substitute real values for
variables (indicated in italics). (See the Configuration Form 1 on page 1-5 and 1-12 for
procedures for determining these values.)
For the ADD SUBNET command, the subnet name can be anything under seven
alphanumeric characters long beginning with a letter. The DEVICENAME attribute is
required. The DEVICENAME attribute specifies the logical interface (LIF) name
associated with the adapter accessed by the Parallel Library TCP/IP processes. (See
Step e on page 1-4 for procedures for determining an appropriate LIF.)
LOOPBACK
When the monitors are started, a subnet named LOOP0 is added automatically. This
subnet provides loopback capability without requiring the use of the TCP/IP network.
When this LOOP0 subnet is created, it has an address of 0.0.0.0 in dotted decimal
form. You must change this address; use the command:
ALTER SUBNET LOOP0, IPADDRESS 127.1
The address 127.1 (or 127.0.0.1) is the standard for loopback operation.
Configuration Example for the Monolithic Listening Model
This example demonstrates the monolithic listener model discussed above (see
Monolithic Listening Model on page 3-4) configured with round-robin filtering enabled.
The startup files and subnet initiation files for establishing the Parallel Library TCP/IP
environment and subnets are the same as Configuration Example for the Standard
Listening Model on page 3-11.
In this example, TCPIPUP3, the main command file, has been changed to use
TELSERV instead of LISTNER to demonstrate the monolithic listener model.
