Tasks can also be configured to run based on system status such as being idle for a pre-configured amount of time, on startup, [20] logoff, or only during or for a specified time. XPath expressions can be used to filter events from the Windows Event Log. Tasks can also be delayed for a specified time after the triggering event has occurred, or ...
System Center Operations Manager: product’s major components. The basic idea is to place a piece of software, an agent , on the computer to be monitored. The agent watches several sources on that computer, including the Windows Event Log , for specific events or alerts generated by the applications executing on the monitored computer.
The underlying program is no longer executing, but the process remains in the process table as a zombie process until its parent process calls the wait system call to read its exit status, at which point the process is removed from the process table, finally ending the process's lifetime.
During system development, CM allows program management to track requirements throughout the life-cycle through acceptance and operations and maintenance. As changes inevitably occur in the requirements and design, they must be approved and documented, creating an accurate record of the system status.
In computer science, an instance is an occurrence of a software element that is based on a type definition. When created, an occurrence is said to have been instantiated , and both the creation process and the result of creation are called instantiation .
Check that the variable is initialized (without obtaining the lock). If it is initialized, return it immediately. Obtain the lock. Double-check whether the variable has already been initialized: if another thread acquired the lock first, it may have already done the initialization. If so, return the initialized variable.
The exact power saving scheme depends on the operating system version and on the hardware and firmware capabilities of the system in question. For instance, on x86 processors under Windows 2000, the idle thread will run a loop of halt instructions, which causes the CPU to turn off many internal components until an interrupt request arrives ...
Connect to a chosen system and browse the CIM repository in any namespace available. Search for classes by their name, by their descriptions or by property names. Review the properties, methods, and associations related to a given class. See the instances available for a given class of the examined system. Perform Queries in the WQL language.
