Few commands to know about solaris box

Mostly Solaris is used as production server since it is more robust.

To find total hard disk space

$ iostat -E

To find how much disk space used

$ du -sh /

  34G  

To find how much disk space used by a directory

$ du -sh /tmp

 869M   /tmp

To find Total RAM

$ /usr/sbin/prtconf -v | head -2

$ /usr/sbin/prtdiag -v | head -3

System Configuration: Sun Microsystems  sun4u Sun Fire V440

To monitor RAM usage by each process

$ top

To know all environment variables that are set

$ env

MANPATH=/usr/share/man:/usr/local/man:/usr/dt/share/man:/usr/openwin/share/man:/usr/local/share/man:/opt/VRTS/man

To know if the solaris running in 32 or 64 bit mode
The isainfo utility can  answer are  whether  64-bit  applications are supported, or whether
the running kernel uses 32-bit or 64-bit device drivers.

$ isainfo -v

64-bit sparcv9 applications
        vis2 vis
32-bit sparc applications
        vis2 vis v8plus div32 mul32

if you get only 32-bit then it is running in 32 bit mode
if you get both 64-bit and 32-bit then it is running in 64 bit mode

The uname utility prints information about the current  system on the standard output.

$ uname -X

System = SunOS
Node = bsdevprem01
Release = 5.10
KernelID = Generic_127111-08
Machine = sun4u
BusType = <unknown>
Serial = <unknown>
Users = <unknown>
OEM# = 0
Origin# = 1
NumCPU = 2

To know the installed JVM is capable of running 64-bit version

$ java -d64 -version

java version "1.5.0_15"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_15-b04)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_15-b04, mixed mode)

if not 64 bit capable you will get some message like

This Java instance does not support a 64-bit JVM. Please install the desired version.

To know how long the serer is up

$ uptime

  5:15pm  up 78 day(s),  8:39,  3 users,  load average: 6.77, 6.75, 7.46
