1.$ SHOW PROCESS OCALA::MALIK
14-DEC-2001 15:35:19.39 User: MALIK Process ID: 28200364
Node: OCALA Process name: MALIK
Terminal: RTA5:
User identifier: [VMS,MALIK]
Base priority: 4
Default file spec: WORK5:[MALIK]
Devices allocated: RTA5:
The SHOW PROCESS command in this example is entered by the
user MALIK. The system displays the subset of information for
the owned process on node OCALA. The information includes the
following:
Date and time the SHOW PROCESS command is entered
User name
Process identification (PID) number
Node name
Process name
Device name of the current SYS$INPUT device
User identification code (UIC)
Base execution priority
Default device (only for processes on the same node)
Default directory (only for current processes)
Devices allocated to the process and volumes mounted, if any
2.$ SHOW PROCESS/ACCOUNTING
14-DEC-2001 14:48:01.31 User: MALIK Process ID: 28200364
Node: OCALA Process name: "MALIK"
Accounting information:
Buffered I/O count: 4878 Peak working set size: 844
Direct I/O count: 1284 Peak virtual size: 1176
Page faults: 6100 Mounted volumes: 0
Images activated: 22
Elapsed CPU time: 0 00:01:20.51
Connect time: 0 04:06:03.75
The SHOW PROCESS command in this example displays the
accounting statistics for the process. The values under Peak
working set size and Peak virtual size are rendered in 512-byte
pages on VAX and in pagelets on Alpha.
3.$ SHOW PROCESS/PRIVILEGES
14-DEC-2001 14:59:28.53 User: MALIK Process ID: 28200364
Node: OCALA Process name: "MALIK"
Process privileges:
GROUP may affect other processes in same group
TMPMBX may create temporary mailbox
NETMBX may create network device
Process rights identifiers:
INTERACTIVE
DIALUP
The SHOW PROCESS command in this example displays the current
privileges for the process.
4.$ SHOW PROCESS/QUOTAS
14-DEC-2001 15:00:28.79 User: MALIK Process ID: 28200364
Node: OCALA Process name: "MALIK"
Process Quotas:
Account name: VMS
CPU limit: Infinite Direct I/O limit: 6
Buffered I/O byte count quota: 17904 Buffered I/O limit: 6
Timer queue entry quota: 10 Open file quota: 31
Paging file quota: 24945 Subprocess quota: 8
Default page fault cluster: 64 AST limit: 14
Enqueue quota: 30 Shared file limit: 9
Max detached processes: 11 Max active jobs: 14
The SHOW PROCESS command in this example displays the available
quotas and limits. The value under Paging file quota is
rendered in 512-byte pages on VAX and in pagelets on Alpha.
5.$ SHOW PROCESS/SUBPROCESSES
14-DEC-2001 15:44:59.39 User: MALIK Process ID: 28200364
Node: OCALA Process name: "MALIK_1"
Processes in this tree:
MALIK
MALIK_1 (*)
MALIK_2
The SHOW PROCESS command in this example shows the current
process tree. The current process is indicated by the asterisk
(*). Processes both below and above the current process are
shown.
6.$ SHOW PROCESS/CONTINUOUS BOB
Process BOB 12:26:53
State CUR Working set 269
Cur/base priority 8/4 Virtual memory 1713
Current PC 7FFEE07E CPU time 00:00:13.82
Current PSL 03C00000 Direct I/O 246
Current user SP 7FF785A4 Buffered I/O 646
PID 226006C0 Page faults 3417
UIC [VMS,BOB] Event flags C8000007
C0000000
SYS$SYSROOT:[SYSEXE]SHOW.EXE
In this example, the /CONTINUOUS qualifier causes the display
of information about process BOB to be updated continuously.
Note that the Virtual memory heading appears on VAX and the
Virtual pages heading appears on Alpha; both indicate the
virtual memory used as a number of CPU-specific pages. The
value displayed for Working set is also a number of CPU-
specific pages.
7.$ SHOW PROCESS/MEMORY
14-DEC-2001 14:59:04.48 User: MALIK Process ID: 28200364
Node: OCALA Process Name: "MALIK"
Process Dynamic Memory Area
Current Size (bytes) 25600 Current Total Size (pages) 50
Free Space (bytes) 22698 Space in Use (bytes) 2902
Size of Largest Block 22496 Size of Smallest Block 15
Number of Free Blocks 7 Free Blocks LEQU 32 Bytes 3
The SHOW PROCESS command in this example displays the use of
dynamic memory areas for the current process, MALIK. These
areas are described as follows:
Current size Displays the current size in bytes and pages
on VAX (512-byte pagelets on Alpha) of each
dynamic memory area.
Free space Displays the amount of free space in each
dynamic memory area.
Space in use Displays the amount of space currently
allocated from each area.
Largest block Displays the size of the largest contiguous
area in each pool area.
Smallest block Displays the size of the smallest free block
in each pool area.
Free blocks Displays the total number of free blocks in
each pool area. The size of this number is a
measure of pool fragmentation.
Blocks LEQU 32 Displays the number of free blocks that are
(VAX) Blocks LEQU 32 bytes or shorter on VAX or 64 bytes or
64 (Alpha) shorter on Alpha. 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.
8.$ SHOW PROCESS OCALA::MALIK
14-DEC-2001 15:35:19.39 User: MALIK Process ID: 28200364
Node: OCALA Process name: MALIK
Terminal: RTA5:
User identifier: [VMS,MALIK]
Base priority: 4
Default file spec: WORK5:[MALIK]
Devices allocated: RTA5:
The SHOW PROCESS command in this example displays the basic
subset of information for the process MALIK on node OCALA.
9.$ SHOW PROCESS/SHELVING LYONS
15-JUNE-2001 10:07:25.11 User: LYONS Process ID: 20206A50
Node: BANANA Process name: "LYONS"
Auto-unshelve: on
The SHOW PROCESS command in this example shows that the LYONS
process automatically unshelves files.
10$ SHOW PROCESS/DUMP RALSTON
31-DEC-2001 10:38:32.48 User: RALSTON Process ID: 20C0011B
Node: AAAAAA Process name: "_RTA1:"
Image Dump: on
The SHOW PROCESS command in this example shows that the image
dump capability for the RALSTON process is enabled. This causes
the contents of the address space to be written to the file
named SYS$LOGIN:(image-name).DMP (where the image name is
the same as the file name) when an image terminates due to
an unhandled error.
See the SET PROCESS/DUMP command for additional information.
