Changes to statistics records

There are changes to CICS® statistics records. These are usually because of new domains, or they are a result of enhancements to CICS. As a result, a number of statistics DSECTs have new or changed fields. The changed DSECTs are:

Copybook
For functional area
DFHDSGDS
Dispatcher global statistics
DFHPIPDS
Pipeline resource statistics
DFHPIWDS
Webservice resource statistics
DFHWBSDS
Urimap global statistics
DFHMNTDS
Transaction performance monitoring resource statistics.
DFHWBRDS
Urimap resource statistics
DFHSORDS
TCP/IP resource statistics

Existing application programs are unaffected by the changes if they use the old versions of the following changed DSECTS:

DFHSORDS

This is because the new fields are added to the end and do not affect the offsets of the unchanged fields.

The changes to DFHMNTDS 1 are such that the old DSECT is not compatible with the new DSECT, and application programs using this DSECT must be recompiled.

New and revised values in DFHSTIDS (statistics record identifiers)

The revised list of the statistics record identifiers, as described in the common statistics record copybook, DFHSTIDS, is shown in the CICS Customization Guide.

The new and revised values in that list are shown in Figure 2.
