2.14.1 Usage Guidelines

 
The TCP/IP Network Resource Planning Standard Application
provides a capacity planning database file with the database
elements you need for basic tracking, reporting, and
forecasting of the TCP/IP Network workloads on your system.
The information for this application is primarily derived
from either the DETAIL, DAYS, WEEKS, or MONTHS timespan of
the CA MICS TCP/IP API Calls for Sockets File (TCPAPI).

In the TCP/IP Network Resource Planning Standard Application,
the application workload group (CAPAPU) data element lets you
group your individual TCP/IP systems into logically similar
workload groups for more meaningful tracking and reporting.
Three methods are provided for specifying the manner in which
the TCP/IP applications are grouped: 1) defining each TCP/IP
application as its own workload group (CAPAPU = NETNAME), 2)
combining all TCP/IP applications (no workload group), 3)
defining your own SAS statements to create the workload
groupings by specifying CAPAPU values.

It may be important to identify specific remote addresses
(TCPRADDR) within your TCP/IP network. The TCP/IP remote
address can be used to subset your TCP/IP volume to further
delineate your TCP/IP volume statistics for planning
purposes.

The TCP/IP TCPAPI file contains an element called NETWRKID.
This element is populated from the SNTNIDRT exit contained
within unit prefix.parms.

Consider the following CA MICS exit example:
 
/*                                                       */
/*  Sample unit prefix.parms(SNTNIDRT) exit              */
/*                                                       */
/* DCAHRND1 listed below can potentially have TCP/IP     */
/*  addresses from 141.202.195.0 to 141.202.195.255.     */
/*                                                       */
/* TCPRADDR is stored as a character.                    */
/*                                                       */
IF TCPRADDR =: '141.202.195.' and ORGSYSID='PRD1'
 THEN
   NETWRKID='DCAHRND1';      /* Herndon Activity DCA1    */
 ELSE
IF ORGSYSID='PRD1'
 THEN
NETWRKID='DCAPROD1';         /* All other SYSID DCAPROD1 */
 ELSE
IF TCPRADDR =: '141.202.255.' AND ORGSYSID='TST3'
 THEN
   NETWRKID='NYCNJ1';        /* New Jersey Activity      */
 ELSE
IF ORGSYSID='TST3'
 THEN
   NETWRKID='NYCPROD1';      /* All other SYSID NYCPROD1 */
 ELSE
   NETWRKID='*UNKNOWN';
/*                                                       */

The above exit example subsets the TCP/IP volume sent to the
remote addresses for New Jersey and Herndon. If necessary,
the data can also be easily recombined during subsequent
reporting for all of the SYSID by adding the statement: "If
NETWRKID=: 'DCA' then NETWRKID='DCAPROD1' ".
 
The NETWRKID provides a method for identifying the volume of
traffic within a given TCP/IP system.
