The EXTDATA Record

The EXTDATA record for CMF data is a superset record containing the appropriate data for all supported releases of CICS along with an area set aside for future expansion. There is also a fixed area to be used by installations to support inclusion of user data that is collected by user event monitoring points (EMPs). The "fixed" user area has been designed to accommodate various monitoring scenarios that an installation might choose. Because the EXTDATA record matches the IRD record format in JARS/OLF and CA PMA Chargeback, it is highly recommended that CA PMA Chargeback users do not modify the format of the IRD or ORD for the CMF record (JARS/OLF users do not have this capability).

A single character user field definition in an EMP may actually be a composition of one or more data fields, thereby designating a group level field. CA PMA Chargeback users have the option in this case to redefine the ORD fixed user field that the data is moved to, for purposes of referencing the individual fields within the group level field. The following fixed user fields are defined in the EXTDATA record:

EXTDATA Name	IRD/ORD Name	Len	Description
EXTC1L04	C1L04	CL4	4 byte character user area
