This article shows you what Solaris commands are commonly used, which are concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

-View processes and loads

Prstat

-View io and cpu

Iostat 2

-View memory, swap space, cpu

Vmstat 2

-View the operating system version

Showrev 、 / etc/release

-View the number of bits

Isainfo-v

-View system configuration information

Prtdiag-v

-Statistics of cpu utilization

Sar-u 2 30

-View process information

Prstat-a

-change memory limit parameters

Projmod-U oracle-K "project.max-shm-memory= (priv,16380MB,deny)" user.oracle

-View restrictions

Solaris10 can be viewed before / etc/system

After solaris10, you can view the changes as follows

Prctl-I process $$

Or ulimit-a.

Or prctl-I project user.oracle

-- memory--

1. Query the total memory

-bash-3.00# prtconf | grep Memory

The result is:

Memory size: 28672 Megabytes

That is, the total memory is 28672m.

2. Query the remaining memory and total memory

-bash-3.00# echo ":: memstat" | mdb-k

The result is:

Page Summary Pages MB Tot

-

Kernel 111524 871 3%

Anon 296480 2316 8

Exec and libs 20382 1591%

Page cache 66403 518.2%

Free (cachelist) 187491 1464

Free (freelist) 2918928 22804 81%

Total 3601208 28134

Physical 3597230 28103

That is, the remaining memory is Free (cachelist) + Free (freelist) = 24268m

Total memory is Physical=28103M

-- cpu--

1. Query the number of cpu

-bash-3.00# mpstat

The result is

CPU minf mjf xcal intr ithr csw icsw migr smtx srw syscl usr sys wt idl

0 22 0 28 27 16 22 0 1 3 0 57 00 0 100

1 100 25 46 16 34 0 1 3 0 45 00 0 100

2 6 0 12 39 13 22 0 13 0 34 00 0 100

3 22 0 11 212 8 46 0 1 3 0 53 00 0 100

16 5 0 16 23 13 18 00 2 0 32 00 0 100

17 4 0 10 46 20 29 0 1 3 0 27 00 0 100

18 4 0 13 23 12 19 00 3 0 28 00 0 100

19 5 0 10 39 7 35 0 1 2 0 28 00 0 100

Return 8 lines indicating that there are 8 cpu

2. Check the main frequency of cpu.

-bash-3.00# psrinfo-v

-- swap--

Output of 'swap-s' is:

Total: 2514952k bytes allocated + 202368k reserved = 2717320k used, 7021424k available

Swap Utilization (%) is:

(2717320 / (27173207021424)) * 100

= 27.9%

But actually Total virtual swap = RAM backed swap + Disk backed swap

Swap-l report disk backed swap usage. It does not report virtual swap usage.

Physical disk swap configured:

# / usr/sbin/swap-l

Swapfile dev swaplo blocks free

/ dev/zvol/dsk/uppool/swap 181,3 8 163839992 163839992

Total Disk backed swap: 163839992 x 512 = 78G
