Solaris things

Solaris 2.7 = Solaris 7, Solaris 2.8 = Solaris 8, Solaris 2.9 = Solaris 9

Models

Sun2

Sun386i

4/x series

x = {100, 200, 300, 400}

600 model x

x = {120, 140, 41, 51}

SPARCstation x

x = {1, 2, 4, 5, 10, 20, Voyager}

Ultra x

x = {1, 2, 5, 10, 30, 60, 250, 450, Enterprise}

SunBlade x

x = {100, 1000, 150, 3800, 4800, 4810, 6800,�}

Others

B100s, V100, V120, V210, V240, V250, 280R, V440, V880, B200x, v20z, v40z

Determining model

/usr/sbin/prtconf

suntype (perl script)

Keyboard

xmodmap

xkeycaps

Memory

Determining physical memory

/usr/sbin/prtconf | grep "Memory size"

/usr/sbin/prtdiag

On high end machines:

usr/sbin/cfgadm -al

Determining virtual memory

swap -s

If po (page out) and sr (scan rate) have high values, more memory should probably be used.

Displaying memory segments

ipcs -m

Determining swap space

/usr/sbin/swap -l

The value shown in the BLOCK columns needs to be divided by 2 in order to get kilo bytes.

Determining installed packages

showrev -p

pkginfo -i package name

Networking

Specifying the nameserver

domain my.domain
nameserver abc.def.ghi.jkl

hosts:      dns files

Adding a gateway

route add default abc.def.ghi.jkl

Configuring the ip address

ifconfig <interface> abc.def.ghi.jkl netmask 255.255.255.0 up

Architecture Name

Performance

top

ftp://ftp.groupsys.com/pub/top/

Solaris 8 and higher ship prstat which offers similar funcionality.

Monitoring

iostat

Disk utilization etc

iostat -p shows disk statistics at the partition level.

mpstat

CPU + Interrupt activity per CPU (that is: per processor statistics)

Also displays the number of CPUs.

netstat

nfsstat

sar

System without network

vmstat

CPU, memory, swap and run queue.

prstat

By default, prstat lists the processes running on a system, sorted by CPU utilization. See also top.

prststat -L: shows each LWP for a multi-threaded process.

prstat -m: includes the percentage of time a process spends in system traps, text page faults, data page faults, waiting for user locks, and waiting for CPU time.

prstat -t: lists the CPU and memory resource usage summary for each user.

pcred

Prints credential (that is effective, real and saved user and group IDs) for each process.

pfiles

On open files of processes.

pflags

/proc tracing flags

pldd

Show dynamic libraries linked into a process.

pmap

Address space of processes.

pstack

prtmem

Displays the system's overall breakdown of the memory layout.

Alternative: mdb

Misc

Listing the system's current shared memory and semaphore segments, and their identification number and owner:

ipcs

Who is accessing a file system (and prevents it from being unmounted)

fuser -c /cdrom/disk1

pstop and prun

Stop and start processes.

uptime

How long is the box already running.

Platforms

sun4m
sun4d
sun4u
???

How to identify platforms?

Lightweight processes (LWPs)

An LWP is a virtual execution environment for each kernel thread within a process. It allows each kernel thread within a process to make system calls independent of other kernel threads within the same process.

Special groups

sys, but what for?

Buzzwords

Predictive self-healing, Service Management Framework (SMF), Solaris Fault Manager, Solaris Zones, Dynamic resource pools (DRP), Physical memory control, Dynamic tracing facility (DTrace), Process rights management, Memory placement optimization (MPO), Resource Manager (RM), Solaris Volume Manager (SVM), Threads library (libthread.so)
