IBM SC34-6814-04 The monitoring control table (MCT)

The monitoring control table (MCT)
Youcan use the monitoring control table (MCT):
vTotell CICS about the EMPs that are invoked by your application programs and
about the data that is to be collected at these points. The DFHMCT TYPE=EMP
macro can do this.
vTotell CICS that you want specific system-defined performance data not to be
recorded during a particular CICS run. The DFHMCT TYPE=RECORD macro can
do this.
Full details of the DFHMCT macros are provided in the CICS Resource Definition
Guide, and you should refer to this when reading the following sections.
