ESunday is more like Monday than it used to be, Places of business that used to keep daytime “business hours” are now open late into the night. And on the Internet, the hour of the day and the day of the week have become irrelevant (不相关的).A half century ago in the United States, most people experienced strong and precise dividing lines between days of rest and days of work, school time and summer time. Today the boundaries still exist, but they seem not clear.The law in almost all states used to require stores to close on Sunday; in most, it no longer does, It used to keep the schools open in all seasons except summer, in most, it still does. And whether the work week should strengthen its legal limits, or whether it should become more “flexible,” is often debated. How should we, as a society, organize our time? Should we go even further in relaxing the boundaries of time until we live in a world in which every minute is much like every other?These are not easy questions even to ask. Part of the difficulty is that we rarely recognize the “law of time” even when we meet it face to face. We know as children that we have to attend school a certain number of hours, a certain number of days, a certain number of years – but unless we meet the truant officer (学监) ,we may well think that we should go to school due to social custom and parents’ demand rather than to the law. As adults we are familiar with “extra pay for overtime working,” but less familiar with the fact that what constitutes(构成) “overtime” is a matter of legal definition. When we turn the clock forward to start daylight – saving time, have we ever thought to ourselves: “Here is the law in action”? As we shall see, there is a lot of law that has great influence on how organize and use time: compulsory education law, overtime law, and daylight – saving law- as well as law about Sunday closing, holidays, being late to work, time zones, and so on. Once we begin to look for it, we will have no trouble finding a law of time to examine and assess.67.

Company.com has a three-node cluster with six resource groups. There are two resource groups for each node. A new hardware component will be added to one of the nodes. The customer wants to move the resource groups to other nodes，but not necessarily in the normal fallover order. Also，the resource groups must be moved at night when there is no one in the computer center. What can be done so that the resource group is moved at the most convenient normal fallover order. Also，the resource groups must be moved at night when there is no one in the computer center. What can be done so that the resource group is moved at the most convenient time for the customer？（） A、 Create a custom resource group with a custom fallback timer to cause the system shutdown at he appropriate time.B、 Set the system to stop with "shutdown" command at the appropriate time and allow HACMP to relocate the resources.C、 Use a script that calls the cIRGmove command and place it in the cron or a queue to execute at the appropriate time.D、 Change the existing resource groups to a custom type and add a timer to perform a "shutdown -h" command at the appropriate time.
