Frequently Asked Questions

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.

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.

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.

How time-consuming is raw food to prepare?

Raw Food Lifestyle - Frequently Asked Questions - Health Fre...
When first going raw you will tend to desire the complicated and filling recipes that replace cooked food meals and are somewhat time consuming to prepare. But as the months go by you will find yourself desiring complex meals less and less, and you will find you are more satisfied with eating whole foods which are as fast as it gets, needing perhaps a little chopping or peeling and that’s it. There are also other benefits to preparing raw food.

Will I be asked to do time consuming chores while in the program?

Youth Drug Addiction Treatment & Rehabilitation Help ? Teen ...
Surprisingly, there are still many treatment programs that require participants to do chores. This is often times justified as an experience designed to “humble” participants. Chores are sometimes even used as a form of punishment. While studies conducted as early as the 1970's clearly refute the therapeutic usefulness of having youth perform such labor, many programs continue to have their participants perform chores as a cost savings measure.

Is the Brailling process expensive or time-consuming?

Frequently Asked Questions about Braille Embossing
There is no charge for Braille embossing for University-related materials. In cases of unusually large requests, departments may be asked to replace the special paper used for embossing. This price is approximately $45 per case (1000 sheets). The amount of time and effort required to emboss a document depends on its initial quality and complexity as well as its length. Generally speaking, the ATL can provide simple Braille documents (less than a hundred Braille pages) within two working days.

Is this time consuming?

ASARD
Yes! Expect to train 3-4 times per week when starting out. You will need a significant amount of support from your spouse, family and employer. This is a serious commitment of your time and resources . In most cases, teams who train inconsistently do not advance towards mission-ready status.

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 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

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.

Is it time-consuming to connect nodes together?

CubicNavigator - Tutorial
No. CubicConnector's overriding design goal was to make it fast and easy to link many nodes together, reducing the number of clicks and scrolling required. Its connection area allows visual correlations to be made easily between a hotspot and its destination.

Will this be very time consuming for businesses?

EBTP
indicated above, registration can be completed quickly by answering a couple of questions about your business – size, sector etc... Before each consultation, businesses will receive a brief summary of the new proposal – why it is being proposed, its overall objectives, etc. This will be short and concise and in easy to understand language. The questionnaire itself will be designed for easy use with the aim to be completed in 15 - 20 minutes.

Is reporting an invention time consuming?

McGill University - Office of Technology Transfer - FAQs for...
Not initially; the inventors only have to fill out a form at first. OTT will start a due diligence process and decide within three months if it files a patent or not. If a patent is filed, the commercialization process may take time and does require further involvement by the inventors. It is important to have the commitment of the inventors throughout the process.

How time-consuming is the configuration ?

frequently asked questions to temperatur, dewpoint and humid...
The basic configuration is very quick. You indicate which sensor is attached to which interface, and the sensor is regularly queried. Then you set which sensor is to be displayed on each of the 12 displays. That concludes the basic configuration. All further adjustments concern visual presentation, e.g. the color of the display elements etc.
