Abstract: A method and system for an unattended installation of any type of a guest operating system (GOS) on a Virtual Machine (VM). Proposed method and system allow users to create an executable script, which provides automation of any GOS installation on the VM. User actions, such as mouse clicks and keyboard strokes, performed during GOS installation are recorded. The delays, time periods between clicks and strokes are recorded as well. All of this information is incorporated into an executable script. The script, when executed, simulates/reproduces GOS action sequence. This sequence reflects the behavior of GOS itself executed on a VM. The executable script is OS-independent and runs on top of system OS.

An internal buffer enables each web server in the web farm to balance their loading based on the contents of the client service request. Data switching between the address portion of the user space and the address portion of the kernel space within the load balancing server is eliminated.

Abstract: A system, method and computer program product for virtualizing a processor include a virtualization system running on a computer system and controlling memory paging through hardware support for maintaining real paging structures. A Virtual Machine (VM) is running guest code and has at least one set of guest paging structures that correspond to guest physical pages in guest virtualized linear address space. At least some of the guest paging structures are mapped to the real paging structures. A cache of connection structures represents cached paths to the real paging structures.

Some of the objects are private and other objects are shared between multiple virtual environments. One virtual environment cannot access private objects of another virtual environment.

Abstract: A system, method and computer program product for managing computer resources in a computer system running an operating system and a plurality of processes grouped into at least two groups. A set of resource limits corresponds to the processes. A scheduler of resource allocation allocates resources to each process such that total resource allocation to a group to which that process belongs remains constant. The scheduler reallocates the resources based on a request for resources over an established limit, a predictive algorithm, or process priority, or based on relative weighting of the processes. The scheduler can reallocate to one of an increase and a decrease of the resources available to a particular process. The scheduler can reallocate the resources to exceed the resource allocation to a particular process while keeping the resource allocation to the group to which that process belongs constant.

Abstract: The present invention is directed to method, system and computer program product for managing dynamic content of website. The proposed method employs processing of database elements by using active descriptors. The active descriptors contain the generic descriptions of the database elements, which properties may change with time. The dynamic descriptors are used for describing database objects. The controls build are universal and can be employed for processing several classes of objects. Each class object has sets of assigned attributes containing additional descriptions of the class object. The proposed method allows using a lightly loaded thin nucleus of the DBMS, which does not contain the information about the class attributes. The class attributes are defined by active descriptors of each particular instance of the class object.
