CICS data section
The CICS data section can be made up of a dictionary data section, a performance
data section, or an exception data section. You can identify which of these you are
dealing with by looking at the value of field SMFMNCL in the SMF product section.
Each of the data section types is described in the sections that follow.
Dictionary data sections
Dictionary data sections describe all the fields in the performance data records that
are gathered during this CICS run. They describe all the system-provided data
fields (whether you have excluded any or not), plus any user-provided data fields,
which CICS takes at initialization time from the MCT entries you have coded. This
means that the descriptions of the system-provided data fields never change,
though the user data fields can be changed each time CICS is initialized. The
contents of the dictionary data sections cannot be changed while CICS is running.
Dictionary data sections contain a variable number of 26-byte dictionary entries.
Each dictionary entry provides the following information about a single performance
record data field:
CMODNAME
The identifier of the group to which the field belongs
CMODTYPE
The field type
CMODIDNT
The field identifier
CMODLENG
The length of the field
CMODCONN
The connector value assigned to the field
CMODOFST
The offset of the field
CMODHEAD
The informal name of the field.
You can map the dictionary entries by generating a DSECT with the DFHMCTDR
macro as shown in Figure 86 on page 667.
