Measure Reference Manual

RECORDS-ACCESSED
Number of records read by the disk process or file system to perform the operations. Number of
records accessed is greater than or equal to the number of records used. The ratio of
RECORDS-USED to RECORDS-ACCESSED indicates the selectivity of the statement. The value of
this counter is zero for Enscribe files.
Counter type: Incrementing.
RECORDS-USED
Number of records returned to the SQL executor on reads, inserts, writes, updates, and deletes.
The value of this counter is zero for Enscribe files.
Counter type: Incrementing.
TIMEOUTS-OR-CANCELS
Number of timeouts or cancels issued against this OPEN.
Counter type: Incrementing.
UPDATES-OR-REPLIES
Number of calls to the WRITEUPDATE or WRITEUPDATEUNLOCK procedure with a buffer length
greater than zero (update operations) or the number of calls to the REPLY procedure (reply
operations). This counter includes both user and system calls to these procedures.
Interpretation of this counter depends on the type of file being measured. Update operations are
performed on disk and tape files. Reply operations are performed on terminals or processes.
Counter type: Incrementing.
WRITE-BYTES
Number of bytes written from a user application buffer. Available for all file open types.
Counter type: Accumulating.
WRITES
In D-series RVUs, number of calls to file-system write operations such as WRITEX, and OSS file
system write APIs such as write() or send(). For OSS, the total includes OSS-CACHE-WRITES. For
the Enscribe file system, the total includes non-DBIO and DBIO operations. This counter includes
both user and system calls to WRITE.
In G-series RVUs, number of calls to the WRITE procedure. This counter includes both user and
system calls to WRITE. In G05 and later RVUs, this counter includes direct bulk I/O write operations.
Counter type: Incrementing.
Legacy Style Only ID Field DDL Definition for FILE Entities
This ID field is used in Legacy Style DDL records only.
OPENER-CPU
(Legacy Style only) Number of the CPU on which the process that opened the file is executing.
Legacy Style Only Counter Field DDL Definition for FILE Entities
This counter field is used in Legacy Style DDL records only.
MESSAGE-BYTES-F
(G-series, Legacy Style only) Same as MESSAGE-BYTES but accommodates larger values (64 bits
rather than 32 bits).
