Slot Usage (slots)
Displays the use of process entry slots and balance set slots.
|
(1) Total
|
Number of process entry slots (the value of the system parameter
MAXPROCESSCNT) and balance set slots (the value of the system parameter
BALSETCNT) permanently allocated when the system was bootstrapped.
|
|
(2) Free
|
Number of slots currently available.
|
|
(3) Resident
|
Number of slots currently used by memory-resident processes. The number
of balance set slots in use can never be any larger than the number of
process entry slots in use because the SWAPPER and NULL processes have
process entry slots but do not require balance set slots.
|
|
(4) Swapped
|
Number of slots used by outswapped processes. For process entry slots,
this number includes all processes that have been partially outswapped.
For balance set slots, this number includes those processes that have
had their process bodies outswapped but have process headers that are
still resident.

Dynamic Memory Usage (in bytes)
Shows the use of the nonpaged and paged pool areas that allocate
variably sized blocks.
|
(1) Total
|
Total number of bytes set aside for each area.
|
|
(2) Free
|
Total amount of free space in each dynamic memory area.
|
|
(3) In Use
|
Amount of space currently allocated from each area. This number is the
total size minus the number of free bytes.
|
|
(4) Largest
|
Size of the largest contiguous block in each area. For the paged pool,
this number represents the largest block that can be allocated. For the
nonpaged pool, an allocation request larger than this number will cause
the nonpaged pool to grow (if other constraints allow growth). This
attribute does not apply to the lock manager, as all items for the lock
manager are the same size.

Dynamic Memory
Shows the use of dynamic memory areas consisting of variably sized
blocks.
|
(1) Current Size
|
Current size (in 512-byte pagelets on Alpha and in bytes and pages on
VAX) of each dynamic memory area. For the lock manager display, the
unit of measurement is megabytes.
|
|
(2) Initial Size
|
Initial size of nonpaged dynamic memory and the name of the system
parameter (NPAGEDYN) that controls this size.
|
|
(3) Maximum Size
|
Maximum size to which nonpaged dynamic memory can grow and the name of
the system parameter (NPAGEVIR) that controls this size.
|
|
(4) Free Space
|
Amount of free space in each dynamic memory area.
|
|
(5) Space in Use
|
Amount of space currently allocated from each area.
|
|
(6) Largest Block
|
Size of the largest contiguous area in each pool area.
|
|
(7) Smallest Block
|
Size of the smallest hole (free block) in each pool area.
|
|
(8) Free Blocks
|
Total number of free blocks in each pool area. The size of this number
is a measure of pool fragmentation.
|
|
(9) Blocks LEQU 64
|
Number of free blocks that are 64 bytes long or shorter. This number is
another measure of pool fragmentation because while allocation of these
small blocks is unlikely, they contribute to the allocation time
whenever an allocation request is made.
|
|
(10) Empty Pages
|
Number of pages that do not have any packets allocated.
|
|
(11) Free Packets
|
Total number of packets not in use. This number is the sum of free
packets from partially used pages and the packets of all Empty Pages.
|
|
(12) Hits
|
Total number of packet allocations.
|
|
(13) Misses
|
Total number of packet allocation requests that could not be satisfied
because the number of packets requested were not available. A miss
causes dynamic memory to expand by one page to satisfy the packet
allocation request.
|
|
(14) Expansions
|
Total number of times that dynamic memory increased by a page to
satisfy packet allocation requests.
|
|
(15) Packet Size
|
Packet size of 256 bytes, which is used by the lock manager to hold
either a lock block data structure or a resource block data structure.
|
|
(16) Lookasides Free Blocks
|
Total number of memory packets that the system has preallocated and
placed on "lookaside lists". If a packet of the correct size is on a
lookaside list, it can be allocated very quickly and efficiently,
however, it can not then be used as part of any other size packet. An
excess of packets on the lookaside list can be a cause for the
inability to allocate other sizes.

SHOW NETWORK
Displays information about network services registered on a node.
Format
SHOW NETWORK [network-service]
Parameter
network-service
Specifies a network service for which you want to display information.
If you do not specify a service, the SHOW NETWORK command displays
information about all services that are currently registered on the
local node.
Description
The SHOW NETWORK command displays information about network services
available on an OpenVMS system.
Qualifiers
/FULL
Displays all the information for the specified network service.
/OLD
If you are running DECnet Phase IV, retains the behavior of the SHOW
NETWORK command prior to OpenVMS Version 7.0. If the local node is a
routing node, the /OLD qualifier provides routing information.
/OUTPUT[=filespec]
/NOOUTPUT
Controls where the output of the command is sent. By default, the
output of the SHOW NETWORK command is sent to the current SYS$OUTPUT
device (usually your terminal).
The asterisk (*) and the percent sign (%) wildcard characters are not
allowed in the file specification.
If you enter the /NOOUTPUT qualifier, output is suppressed.
Examples
| #1 |
$ SHOW NETWORK
Product: DECNET Node: VADIR Address(es): 24.365
Product: TCP/IP Node: vadir.lkr.dec.com Address(es): 161.114.99.17
|
This command was executed on a system running DECnet Phase V and
TCP/IP. It indicates that the DECNET and "TCP/IP" network-service
parameters are valid for this system.
| #2 |
$ SHOW NETWORK "TCP/IP"
Product: TCP/IP Node: vadir.lkr.dec.com Address(es): 161.114.99.17

When the TCP/IP network-service parameter is used, it must be enclosed
in enclosed in quotes because it contains a slash.

SHOW PRINTER
Displays the current settings for a printer.
Format
SHOW PRINTER device-name[:]
Parameter
device-name[:]
Specifies the name of the printer for which settings are to be
displayed.
Description
The SHOW PRINTER command displays the settings that are currently
defined for the specified printer. Settings include the following:
Printer type
Page width
Page length
Line termination type
|
Form feed
Case
Character translation
Wrapping
|
Printer settings are established by the SET PRINTER command. You must
have OPER (operator) privilege to use the SET PRINTER command.
Qualifier
/OUTPUT[=filespec]
/NOOUTPUT
Controls where the output of the command is sent. By default, the
output of the SHOW PRINTER command is sent to the current SYS$OUTPUT
device (usually your terminal). To send the output to a file, use the
/OUTPUT qualifier followed by a file specification.
The asterisk (*) and the percent sign (%) wildcard characters are not
allowed in the file specification. If you enter a partial file
specification (for example, specifying only a directory), SHOW is the
default file name and .LIS is the default file type.
If you enter the /NOOUTPUT qualifier, output is suppressed.
/IDSTRING
Returns the USB printer ID string as a text string and displays it on
your screen. This information appears at the end of the typical SHOW
PRINTER command display.
/SERIALNUM
Returns the USB printer serial number as a text string and displays to
the screen. The USB printer returns the serial number in Unicode
format, and this is converted to ASCII text before being displayed.
