By default, everything is in the "default" resource pool - all CPUs, and all zones. That pool contains any CPUs not specifically assigned to another pool. The only zones that will use a resource pool other than the default pool are those zones that you specifically assign to a different pool. All other zones will use the default pool. That includes the global zone. -- Jeff VICTOR Sun Microsystemsjeff.victor @ sun.com OS AmbassadorSr. Technical Specialist Solaris 10 Zones FAQ:http://www.opensolaris.org/os/community/zones/faq -- ___ zones-discuss mailing list zones-discuss@opensolaris.org

[zones-discuss] Re: limiting a percentage of CPU resource on a zone
well it looks like in the revision of S10 I am running, it does not support this, re-installing is not an option, I attempted using the pools, but to be honest, it is a bit confusing. I believe I setup the prtcl configuration to manage the CPU's correctly, I hope. Basically, I would like to use pools, but I'm getting a headache trying to figure it out. Also, assigning memory to a specific zone, the example given also is not supported in my version, so is there another way of assigning xgb's of memory to a zone thanks humbly yours, Mr green zonecfg -z somezone add dedicated cpu set ncpus=2-8 end This message posted from opensolaris.org ___ zones-discuss mailing list zones-discuss@opensolaris.org
Re: [zones-discuss] Re: limiting a percentage of CPU resource on a zone
Now (Solaris 10 up through 11/06) you can configure the Resource Capping Daemon (rcapd) in the zone. See page 19 of my Containers Architecture BluePrint: http://www.sun.com/blueprints/0506/819-6186.pdf for a complete explanation. In the current build of OpenSolaris, and the next release of Solaris 10 (the one with the Duckhorn enhancements) it is much easier, and the zone cannot change its own cap. For an existing zone, the zonecfg(1M) syntax looks like this: global# zonecfg -z myzone add capped-memory set physical=4g end exit You can also modify the cap while the zone is running, with rcapadm: global# rcapadm -z myzone -m 5g DJR wrote: thank you for all the good information, I appreciate it, I now have just do it since I now have the knowledge given by y'all one last thing. assigning phyiscal memory, we have 16gb of memory on our server, I want to assign 4gb to our zone and leave 12gb for the global zone. -- -- Jeff VICTOR Sun Microsystemsjeff.victor @ sun.com OS AmbassadorSr. Technical Specialist Solaris 10 Zones FAQ:http://www.opensolaris.org/os/community/zones/faq -- ___ zones-discuss mailing list zones-discuss@opensolaris.org
