5.14 Alpha SDA Commands, Parameters, and Qualifiers
5.14.1.3 SHOW MEMORY
The SHOW MEMORY command displays the availability and usage of those
memory resources that are related to memory.
There are no parameters for this command. The following shows the qualifiers
for the SHOW MEMORY command, which are the same as for the existing DCL
command:
Qualifier Meaning
/ALL Displays all available information; that is, information
displayed by the /FILES, /PHYSICAL_PAGES, /POOL, and
/SLOTS qualifiers. This is the default display.
/BUFFER_OBJECTS Displays information about system resources used by buffer
objects.
/CACHE Displays information about the Virtual I/O Cache facility.
The cache facility information is displayed as part of the
SHOW MEMORY and SHOW MEMORY/CACHE/FULL
commands.
/FILES Displays information about the use of each paging and
swapping file currently installed.
/FULL Displays additional information about each pool area or
paging or swapping file currently installed, when used
with the /POOL or the /FILES qualifier. This qualifier is
ignored unless the /FILES or the /POOL qualifier is specified
explicitly. When used with the /CACHE qualifier, /FULL
displays additional information about the use of the Virtual
I/O Cache facility.
/GH_REGIONS Displays information about the granularity hint regions
(GHR) that have been established. For each of these regions,
information is displayed about the size of the region, the
amount of free memory, the amount of memory in use, and
the amount of memory released to OpenVMS from the region.
The granularity hint regions information is also displayed as
part of SHOW MEMORY, SHOW MEMORY/ALL, and SHOW
MEMORY/FULL commands.
/PHYSICAL_PAGES Displays information about the amount of physical memory
and the number of free and modified pages.
/POOL Displays information about the usage of each dynamic
memory (pool) area, including the amount of free space
and the size of the largest contiguous block in each area.
/RESERVED Displays information about memory reservations.
/SLOTS Displays information about the availability of partition
control block (PCB) vector slots and balance slots.
5.14.1.4 SHOW RAD
The SHOW RAD command displays the settings and explanations of the RAD_
SUPPORT system parameter fields, and the assignment of CPUs and memory to
the Resource Affinity Domains (RADs). This command is only useful on platforms
that support RADs. By default, the SHOW RAD command displays the settings
of the RAD_SUPPORT system parameter fields.
