Step 1 (B): Select a TCPSAM Process and SUBNET

for Parallel Library TCP/IP Use

Step 1 (B): Select a TCPSAM Process and

SUBNET for Parallel Library TCP/IP Use

Step 1 (B) is for use with the Parallel Library version of TCP/IP only.

The Parallel Library version of TCP/IP only supports SUBNETs of type Ethernet.

A Parallel Library TCP/IP SUBNET associates the Parallel Library TCP/IP environment

with a connection to a network and an IP address.

Select a TCPSAM Process

The TCP/IP socket access method (TCPSAM) is the process that provides access to

the Parallel Library TCP/IP environment. In configuring Expand-over-IP for this

environment, you will be using the name of a TCPSAM process for the

ASSOCIATEDEV modifier in Step 4: Create the Line-Handler Process.

To obtain a list of running TCPSAM processes, issue the following command:

> LISTDEV TCPIP

The SCF LISTDEV command lists all the TCP/IP processes. A program name in the

SCF LISTDEV display of TCPIP means that it's a conventional NonStop TCP/IP

process whereas a program name of TCPSAM means it's a Parallel Library TCP/IP

process. Example 8-3 shows a sample result of the SCF LISTDEV TCPIP command.

In the above example, the processes $ZSAM1 and $ZSAM2 are TCPSAM processes.

For the rest of this procedure, we will use $ZSAM1 as our TCPSAM process.

Note. The following instructions assume that a Parallel Library TCP/IP environment has

already been started. For information about starting a Parallel Library TCP/IP environment,

refer to the TCP/IP (Parallel Library) Configuration and Management Manual.
