6.1.8 IBM TCP/IP (TCP)

TCP/IP provides statistics for the use of TCP by
applications.  The applications include Telnet, FTP, and API
Calls.  TCP/IP allows cross-platform communication in a
sysplex.

The CA MICS Network Analyzer supports TCP/IP in an IBM
mainframe environment, which writes the SMF type 118 and 119
record types and provides information about the following
components:

o  Telnet - records data for Telnet Client and Telnet Server
   session initiation (logon) and session termination
   (logoff) statistics.

o  File Transfer Protocol (FTP) - records data for FTP Client
   and FTP Server commands issued, for example, STOR, RETR,
   REN, DELE.

o  API Calls - records data for API Calls or TCP initiation
   as well as termination statistics.

To log IBM's TCP/IP records to SMF, see the IBM documentation
for TCP/IP. Since z/OS 1.2, you can log SMF 118 or the new
SMF 119, or both.  Refer to Section 7.2.1 for information on
how to specify the SMF record number for TCP/IP to the CA
MICS Network Analyzer.

You may have both TCP/IP SMF records (118 and 119) defined to
CA MICS Network Analyzer.  To avoid duplicate data in the CA
MICS database files, the CA MICS Network Analyzer lets you
process only one SMF record type for a unique ORGSYSID.  This
is accomplished by coding this statement:

IBMTCP SMF = nnn, where nnn is either the 118 or 119

Refer to Section 7.3.1 for information on coding guidelines.

A message will be issued to inform you of the presence of
TCP/IP data detected from SMF records that are not defined in
the prefix.MICS.PARMS(SNTOPS).  This situation can arise when
the system programmer makes a switch from SMF 118 to SMF 119
(or vice versa), before you can update the SNTOPS member to
reflect the switch that has taken place.
