Entity Specification Syntax for DISCOPEN Entities
To describe DISCOPEN entities:
DISCOPEN entity-spec [,entity-spec] ...
DISCOPEN
collects information about physical access to one or more disk file opens. The measured file
must be local. However, the processes accessing that file can be local, remote, or both.
entity-spec
is defined as:
diskfile [ ( [ \system-name, ] cpu, pin )]
where:
diskfile
is the file to be measured. Specify diskfile as one of the following:
{ * }
{ [[$device.]subvolume.]filename[:crvsn] }
{ [$device.]#tempfile }
{ “pathname” }
{ ‘{TABLE|INDEX} [[catalog.]schema.]object[ PARTITION partition]’ }
{ ‘SCHEMA [catalog.]schema’ }
{ ‘CATALOG {catalog|*}’ }
where
*
measures all file opens.
$device
is the name of the volume (device) that contains the file to be measured. To indicate all
volumes, use an asterisk (*). The default is the current default volume.
subvolume
is the name of the subvolume that contains the file to be measured. To indicate all
subvolumes, use an asterisk (*). The default is the current default subvolume.
filename
is the name of the file to be measured. To indicate all files except temporary files, use
an asterisk (*). Temporary files are specified separately.
:crvsn
(Measure G09 and later PVUs) is the timestamp, creation version serial number (CRVSN),
or file name extension necessary to form a unique file name. Use this option to guarantee
file name uniqueness. The CRVSN is available from the Measure report and the
LISTGNAME command.
#tempfile
is the file identification number of a temporary file to be measured. To indicate all
temporary files, use an asterisk (*).
"pathname"
(Measure G09 and later PVUs) is either a fully qualified or partial OSS file pathname.
An OSS file pathname that does not begin with a slash (/) is considered to be a partial
pathname and is expanded by prefacing it with the current setting for OSSPATH. An
OSS file pathname that begins with /G is not supported, use the Guardian file name
instead.
