Setting memory parameter for running zones
You can change memory parameter for running zones. But remember to make it persistent by changing zone config file, too. So I do it always in advance.
Change setting in the config file
<syntaxhighlight lang=bash>
- zonecfg -z myzone
zonecfg:myzone> select capped-memory zonecfg:myzone:capped-memory> info capped-memory:
[swap: 10G]
zonecfg:myzone:capped-memory> set swap=16G zonecfg:myzone:capped-memory> set physical=16G zonecfg:myzone:capped-memory> set locked=10G zonecfg:myzone:capped-memory> info
physical: 16G
[swap: 16G]
[locked: 10G]
zonecfg:myzone:capped-memory> end zonecfg:myzone> verify zonecfg:myzone> commit zonecfg:myzone> exit
</source>
Change settings for the running zone
First take a look
<syntaxhighlight lang=bash>
- zlogin myzone prtconf | grep Memory
prtconf: devinfo facility not available Memory size: 65536 Megabytes
- prctl -t privileged -i zone myzone
zone: 1: myzone NAME PRIVILEGE VALUE FLAG ACTION RECIPIENT zone.max-swap
privileged 10.0GB - deny -
zone.cpu-shares
privileged 1 - none -
</source>
Set the new values
<syntaxhighlight lang=bash>
- rcapadm -z myzone -m 16G
- prctl -n zone.max-swap -v 16g -t privileged -r -e deny -i zone myzone
- prctl -n zone.max-locked-memory -v 16g -t privileged -r -e deny -i zone myzone
</source>
Prove values
<syntaxhighlight lang=bash>
- zlogin myzone prtconf | grep Memory
prtconf: devinfo facility not available Memory size: 16384 Megabytes
- prctl -t privileged -i zone myzone
zone: 1: myzone NAME PRIVILEGE VALUE FLAG ACTION RECIPIENT zone.max-swap
privileged 16.0GB - deny -
zone.cpu-shares
privileged 1 - none -
</source> Done.
