6.5 Network Data


VM Network data includes NPM, NetSpy, NetView, and NET/MASTER
data.  It may reside on disk or tape.  Only disk-resident
files may be concatenated to the same ddname and be processed
together.  Different tape input files must be transferred
separately.

Each network record contains a standard SMF header record,
identifying the record type, time, date, and system
identifier:

     RDW DS H Record descriptor word
              DS H Reserved
     SMFSIND DS X System indicator
     SMFRTY DS X Record type
     SMFTIME DS XL4 Time, in hundredths of a second
     SMFDATE DS PL4 Date record was created
     SMFSID DS CL4 System identification

Based on the record type, each network record contains
variable data sections.  A record subtype field identifies
the event that caused the record to be written and determines
the type of data sections present.  These subtypes are:

     NPMRST DS XL2 NPM record subtype
     NSPRST DS X NetSpy record subtype
     NLDRST DS XL2 NetView and NET/MASTER record subtype

All supported network data should be in variable record
length format.  Please refer to Section 3.1 for a list of
record types supported by the VM Data Transfer Program.

If you use CA's NetSpy/VM product,refer to the NetSpy
Installation and Customization Guide for information on
having NetSpy generate SMF data.  Briefly, review the
following initialization parameters (the INITPRM file):

1)  To make NetSpy write the system identifier into SMF
    records, specify HOSTID=sysid, where sysid is the system
    identifier to be written into the SMF SYSID (SMFSID)
    field

2)  In the LOGTYPE= parameter, specify the SMF record number
    used for data generated by NetSpy.

    The SMF record number you specify here must also be coded
    in the VM Data Transfer Program's VMTXMIT parameter, in
    the network data selection file, on the NETSPY statement.
    This enables the transmission program to recognize the
    record number.

3)  Specify ACCTING=YES if Network Accounting data (type C)
    is to be collected.

The SMF SYSID field in NetView and NET/MASTER records may
contain a binary zero if it is uninitialized.  The VM Data
Transfer Program will place the value specified in the SYSID
statement in the VMTXMIT record selection parameters into the
SMF SYSID field for NetView and NET/MASTER records (types 37
and 39).
