5.2.3.3 CICCDC Usage Considerations
This section identifies some special considerations or
techniques related to using the CICCDC file.
1. This file exists only in cycle 01 at the DETAIL timespan.
One observation is created for each field defined by the
dictionary record for each CMF class and CICS region.
The CICS Analyzer processes the CMF data using the most
current version of the data dictionary record read from
input. However, if the input does not contain data
dictionary records, CMF data is processed using the
dictionary records stored in the CICCDC01 file from
previous DAILY runs. If CICCDC01 is empty, the CMF data
is rejected until the data dictionary record is read from
input.
2. This file contains data dictionary records from multiple
DAILY runs. The data is deleted when the number of
unreferenced days reaches the threshold defined by the
CICCDCEX parameter in prefix.MICS.PARMS(CICTHRSH). For
more information on this threshold definition, please
refer to Section 7.3.8 in this guide.
