Can I prevent a non-global zone from consuming all the memory?

Learning Solaris 10 & Zones : Unofficial FAQ
Yes! And no… The reource capping feature of Solaris Resource Management allows one to set an upper bound to the amount of RAM used by a certain project. By creating projects inside a non-global zone and setting the rcap.max-rss project parameter, you can limit the amount of memory used by all the processes belonging to that project. So it is not a zone-aware feature but it can be used within non-global zones through the use of projects.

Can I prevent one non-global zone from consuming all the CPU time?

Learning Solaris 10 & Zones : Unofficial FAQ
Yes! The standard Resource Management features have been extended to zones. The Fair Share Scheduler is a scheduling class controlling the proportion of CPU time that a certain entity may use. The administrator of the Global zone is in charge of setting the new ressource control zone.cpu-shares to assign a number of shares to each non-global zone ( the Global zone is assigned 1 share by default ).

Can I prevent one application in a non-global zone from using all the CPU time?

Learning Solaris 10 & Zones : Unofficial FAQ
Yes! The Resource Management model being hierarchical, the first thing to do is to assign a number of shares to each non-global zone ( See 5.1 ). Within the non-global zone, the non-global zone administrator may now create projects in the standard way to differentiate between workloads running in the same non-global zone. Resource contention between these workloads can be resolved by assigning FSS shares to the projects.

How do I configure a default route for a non-global zone?

Learning Solaris 10 & Zones : Unofficial FAQ
there is only one TCP/IP stack, the complete network information must be configured from the Global zone. The Global zone administrator can add one (or more) default route for each subnet, the kernel will make sure that the right one is used for each non-global zone depending on its IP & netmask.

Is it possible to clone a non-global zone?

Learning Solaris 10 & Zones : Unofficial FAQ
Not yet but it will be eventually. A Sun engineer has started working on this. More information. If you can live with an unsupported procedure, have a look at this lab.

Why is snoop not working in a non-global zone?

Learning Solaris 10 & Zones : Unofficial FAQ
Snoop works by talking to the “DLPI” interface that itself contacts the appropriate NIC drivers. To implement the network isolation feature of non-global zones, access to DLPI and the lower levels interfaces is disallowed.

Can I change a non-global zone IP while it is running?

Learning Solaris 10 & Zones : Unofficial FAQ
Yes. Just use the “ifconfig” command from the Global zone. Don’t forget to also update the non-global zone’s configuration if you want the change to be persistent.

Can I add access to a filesystem to a non-global zone while it is running?

Learning Solaris 10 & Zones : Unofficial FAQ
Yes, as long as it doesn’t require the exporting of a new disk device to the non-global zone. See Question 2.5 & Question 3.7

How do I restore a non-global zone’s configuration?

Learning Solaris 10 & Zones : Unofficial FAQ
Configurable only from the Global zone. A restriction is that IPFilter cannot be used to restrict access between 2 non-global zones. The loopback interface is used for that purpose and IPFilter cannot be used to inspect packets goign through that interface. See question 3.2. Starting with Solaris 10 06/06, Zfs is available as a standard supported feature. A siple HOWTO document describes few of the possibilities of integrating Solaris Zones & ZFS. Read the document or go to the sun.

Can I run a non-global zone processes on specific CPUs?

Learning Solaris 10 & Zones : Unofficial FAQ
Yes! First create a processor set that contains some of your CPUs ( be careful, you still need some CPU time for the Kernel! ). Then create a resource pool and bind the processor set to it. Finally bind your non-global zone to the same resource pool. All the processes running in your non-global zone will then run on the CPUs you selected by creating the processor set.

What is Being Done to Prevent the Global Spread of the Bird Flu Virus?

Avian Bird Flu FAQ - Frequently Asked Questions
To help prevent its spread, many Governments and health officials are working hard to bring about a greater civilian awareness of the dangers of avian flu and the importance of swift precautionary action when new cases are identified or infections suspected in both birds and/or humans.

How do I configure the identity (hostname, timeserver, timezone,… ) of a non-global zone?

Learning Solaris 10 & Zones : Unofficial FAQ
After the non-global zone has been installed, all kind of typical identity information needs to be provided. It can be done in two ways: Interactively : the Global zone administrator boots the zone for the first time. A “sysidtool” process ( the same that the one used for a standard installation ) is then launched inside the non-global zone. The administrator needs then to connect to the non-global zone console using the “zlogin -C my-zone” command.

Can consuming B17 tablets really help me fight and prevent cancer?

If you have first been diagnosed and you're starting B17 therapy without chemo or radiation treatment, you should be fine. Dr. Krebs claimed a 98% success rate and the Del Rio Hospital of Tijuana claims nearly a 100% success rate with virgin cases. A virgin case is an individual that has not had chemo or radiation. In cases where the individual has had chemo and /or radiation, it depends on how far the cancer has spread and what damage has been done by the chemo and radiation.

How much memory should I give it?

MT-NW Manual: Frequently Asked Questions
Important Note: Your humble authors got tired of writing dry formal technical prose in the rest of this document, and succumbed to the temptation to try to be funny in parts of this appendix. Sarcasm abounds here. Please do not take any of this personally! The humor-impaired should interpret my comments not as attacks on them, but as an attempt to make fun of myself for being impatient with you, my devoted and valued, if sometimes demanding, users.

How Much Memory Do I Have?

All of Memory FAQ
Consult your user/owner's manual for details about the original memory configuration and capacity. If you've misplaced the manual, you may be able to contact the retailer where you bought the PC from. If you have a hand-me-down PC or inherited a pre-owned PC, you probably may not have the user manual or know any detail of the original memory configuration or the memory configuration may have been changed.

HOW TO TELL ECC, PARITY MEMORY FROM NON-ECC, NON- PARITY MEMORY?

Memory Upgrades for PC or MAC from Data Memory Systems
If your system has ECC or parity memory the chips are evenly divisible by three. How do you know which one you have? One way is to look at the part numbers on the chips of your module. If each chip has the same part number, you have ECC. If one chip is different, you have parity.

How do I backup non-global zones?

Learning Solaris 10 & Zones : Unofficial FAQ
The main question is whether you need to perform the backup from the Global zone or from the non-global zone. You have some enterprise backup software like NetBackup or Legato Networker. Even “ufsdump” requires access to devices which might not be available from the non-global zone. You want to be able to restore your entire zone, not only the data it contains. Main example is Disaster recovery.

How can I prevent Memory Loss?

FAQ
It is vital that our brain be calm, receive sound sleep, and have good blood circulation for an efficient memory. To this end, frequent vigorous exercise is important, and also sufficient Omega 3 fats and CoQ10 which can be obtained from our CoQ10-Omega3. The minerals in our CAA capsules taken with the evening meal also seem to help in this area.
