Solaris 10 - capping CPU

Hi all

I've purchased a T3-1 server. The T3-1 has a 16 core CPU. I want to create a zone to install an Oracle DB server in. Due to Oracle licensing issues I want to limit the zone to 8 cores. I've done some research and it seems there are 2 ways of setting a CPU core limit for a zone.

1. Implement resource management (separate from zone)
2. Set the "capped-cpu" value on the zone itself

Can anyone provide me with some advice on how I can accomplish this form of "hard partitioning" to ensure my zone only uses a max of 8 cores.

Many thanks

NAME
Apache::Session::Oracle - An implementation of Apache::Session SYNOPSIS
use Apache::Session::Oracle; #if you want Apache::Session to open new DB handles: tie %hash, 'Apache::Session::Oracle', $id, { DataSource => 'dbi:Oracle:sessions', UserName => $db_user, Password => $db_pass, Commit => 1 }; #or, if your handles are already opened: tie %hash, 'Apache::Session::Oracle', $id, { Handle => $dbh, Commit => 1 }; DESCRIPTION
This module is an implementation of Apache::Session. It uses the Oracle backing store and no locking. See the example, and the documentation for Apache::Session::Store::Oracle for more details. USAGE
The special Apache::Session argument for this module is Commit. You MUST provide the Commit argument, which instructs this module to either commit the transaction when it is finished, or to simply do nothing. This feature is provided so that this module will not have adverse interactions with your local transaction policy, nor your local database handle caching policy. The argument is mandatory in order to make you think about this problem. This module also respects the LongReadLen argument, which specifies the maximum size of the session object. If not specified, the default maximum is 8 KB. AUTHOR
This module was written by Jeffrey William Baker <jwbaker@acm.org>. SEE ALSO
