Measure Reference Manual

DDL Record for DISKFILE Entities (Legacy Style)
The Legacy Style DDL record for DISKFILE entities will not change after the Measure G10 PVU.
The fields included in BRIEF reports are in boldface type.
The DDL record for G-series DISKFILE entities is identical to the record for D-series DISKFILE entities
except that counters are added to support direct bulk I/O and SQL actions. (Existing I/O counters
such as DRIVER-INPUT-CALLS also include direct-bulk I/O operations.) In addition, new identifiers
have been added for OSS file pathname support.
RECORD diskfile. FILE is "diskfile" ENTRY-SEQUENCED.
