Limiting resource usage for Solaris zones

Posted on May 18th, 2011

Global zone: 75% cpu shares, all ram
SAP zone: 25% cpu shares 8G RAM, 20G swap

global
/etc/init.d/cpushares
(try smf as mentioned in sun blueprint about zone architecture)

#!/sbin/sh
/usr/bin/prctl -n zone.cpu-shares -v 75 -r -i zone global
/usr/bin/prctl -r -n zone.cpu-shares -v 75 -i process $$
exit 0

rcapadm -E
rcapadm -i sample=2

bash-3.00# rcapadm
state: enabled
memory cap enforcement threshold: 0%
process scan rate (sec): 15
reconfiguration rate (sec): 60
report rate (sec): 5
RSS sampling rate (sec): 2
bash-3.00# svcs -a | grep rcap
online May_14 svc:/system/rcap:default
bash-3.00#

move all the processes to FSS sheduler

# dispadmin -d FSS
# priocntl -s -c FSS -i all

zonecfg -z sap

How to create environment for new users in Solaris

Posted on March 17th, 2011

You need to customize environment for new users of your nice Sun server.
No problem. Just create skeleton profile for bash:
/etc/skel/.bash_profile

if [ "`tty`" != "not a tty" ]
 then           
     if [ "`tty`" = "/dev/console" ]
     then
         TERM=vt100
         export TERM
         echo ""
         echo "TERM=$TERM"
         echo ""
     else
         LOGINFROM=`who am i | cut -f2 -d"(" | cut -f1 -d")"`
         DISPLAY=${LOGINFROM}:0.0
         EDITOR=vi
         PS1="\u@\h:\w-(\!)->"
         PATH=$PATH:/usr/local/bin:/bin:/usr/bin:/usr/ccs/bin:/opt/SUNWspro/bin
         export LOGINFROM DISPLAY EDITOR PS1 PATH
         echo ""
         echo "DISPLAY=$DISPLAY"
         echo ""
     fi
 fi

And add user:

useradd -D -b /export/home
groupadd bob
useradd -g bob -s /bin/bash -m bob
passwd bob

Next time bob login he sees nice bash prompt, and other environment variables he needs.

bob@sunserver:~-(1)->
