factors. For an explanation of the setting of the other bits, refer to the
z/OS MVS System Management Facilities (SMF) manual.
2. Fields SMFMNDCA SMFMNDCL, and SMFMNDCN apply to performance
class records only.
3. For dictionary class monitoring records (described in “Dictionary data
sections” on page 754), the fields SMFMNDRA, SMFMNDRL, and
SMFMNDRN in the SMF product section have the following meaning:
SMFMNDRA
Offset to the first dictionary entry.
SMFMNDRL
Length of a single dictionary entry.
SMFMNDRN
Number of dictionary entries within the CICS data section.
4. For performance class and exception class monitoring records, the fields
SMFMNDRA, SMFMNDRL, and SMFMNDRN, in the SMF product
section have the following meaning:
SMFMNDRA
Offset to the first performance or exception class record.
SMFMNDRL
Length of each performance or exception class record.
SMFMNDRN
Number of performance class records in the data section, but for
exception class records this value is always 1.
5. For transaction resource monitoring records, the fields SMFMNDRA,
SMFMNDRL, and SMFMNDRN, in the SMF product section have the
following meaning:
SMFMNDRA
Offset to the first transaction resource monitoring record.
SMFMNDRL
This value is always zero because the transaction resource
records in the data section are variable length. The length of
each record is in the halfword field MNR_LENGTH at the start of
each record.
SMFMNDRN
Number of transaction resource monitoring records in the data
section.
6. The copy book DFHSMFDS is also provided and can be used to map the
SMF header and the SMF product sections of all six subtypes of SMF
110 records written by CICS journaling, CICS monitoring, CICS statistics,
the TS data sharing server, the coupling facility data table (CFDT) server,
and the named counter sequence number server.
7. The SMFMNCRL field indicates whether the CICS data section in this
monitoring SMF 110 record contains compressed data. A zero value in
this field indicates that the CICS data section in the record does not
contain compressed data. A non-zero value in this field indicates that the
CICS data section in the record does contain compressed data, and that
the z/OS Data Compression and Expansion Services must be used to
expand the data section before processing. For more information on data
compression, see Data compression for monitoring records.
