While certainly possible, assigning CPU and memory to a zone isn't a requirement. It is usually better to let them shared between zones unless you have specific requirements.

yeah, the "fair share scheduler" is doing a pretty good job with solaris zones...

Hi,

I would use FSS aswell, as the underlying resources arent that meaty. Let the FSS decide, also later on you can always enforce shares if you want.

The next question is whether you want sparse / or non sparse zones ? i.e. non-sparse = complete copy of the OS or sparse when you are sharing the global zone's core directories e.g. lib /bin etc etc. I would opt for non-sparse due to the sizr of your root drives / applications.

After that, Shared / Exclusive ip ?? I would imagine, due to the level of resources on your server, you would go for shared-ip. Makesl ife far easier.

So, an example of the zone config would be :-

create -b
set zonepath=/zones/roots/app-svr
set autoboot=true
set bootargs="-m verbose"
# Zone CPU Resources
set scheduling-class=FSS
# Zone Network Configurations
set ip-type=shared
add net
set address=X.X.X.X/25
set physical=qfe1
set defrouter=X.X.X.X
end
add attr
set name=comment
set type=string
set value="Application Server"
end

Put all that into a file call app1.cfg, then assuming the hostname is app-svr :-

# zonecfg -z  app-svr  -f app1.cfg
# zonecfg -z  app-svr   verify

# zoneadm list -icv    - lists all zones
# zoneadm -z app-svr install
# zoneadm -z app-svr  ready
# zoneadm -z app-svr  boot

# zlogin -C app-svr

:slight_smile: Easy.

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags

```text
 and 
```

by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.
