Whenever the monitoring of performance class data is switched on, whether at
CICS initialization or while CICS is running, a dictionary data section is written. So,
if the monitoring of performance class data is switched on and off three times
during a single CICS run, there are three separate, but identical, dictionary data
sections for that run. The dictionary data section is passed to SMF, together with
any performance data sections, when the first buffer of performance data sections
for a performance class data monitoring session is output to SMF. Any offline utility
should use the most recent dictionary record encountered when processing CICS
monitoring records.
The format of dictionary data sections is shown in Figure 87. A list of the default
CICS dictionary entries is given in Figure 88 on page 668.
