摘要:
Disclosed are techniques for determining the status of virtual machine sessions on a computing device for a user by reading from a memory location written to by a program executing within a virtual machine. The memory location is preferably a registry key that contains the status of a remote user session operating on a guest operating system operational on the virtual machine, the virtual machine executing in a virtual environment comprising a plurality of virtual machines operating on a computing device.

Embodiments of the present invention monitor and dynamically allocate computing resources to game sessions running within a game service. A game service provides a remote gaming environments to which users connect over a wide area network, such as the internet. A game session runs a single instance of a game title. The game session runs the video game code responsible for creating the playing experience for the users. Various characteristics of the game session may be monitored and used to allocate computing resources. Usage of computing resources, such as central processing unit (“CPU”) may be monitored directly. In another embodiment, the number of players connected to the game session is monitored and computing resources are allocated dynamically as the number of players increases or decreases.

Apparatus, processes, and computer readable storage media for processing received packets. A session memory, coupled to and shared by a plurality of packet processors, may store configuration and statistics information for a plurality of communication sessions. A session active memory may store session identifiers corresponding to packets currently being processed by the plurality of packet processors. A comparator may compare a session identifier extracted from a received packet with the stored session identifiers to determine if another packet belonging to the same session as the received packet is currently being processed. Forwarding logic may distribute received packets among the plurality of packet processors. In the case that another packet belonging to the same session as the received packet is currently being processed, the forwarding logic may wait until the processing of the another packet is complete before sending the received packet to one of the packet processors.

A method and apparatus for establishing a security inflow contract between a work-initiating system and a work-performing system. A portable, generic security inflow contract between an EIS/connector and an application server is provided that enables the connector to establish security information while submitting a work instance for execution to a work manager and while delivering messages to message endpoints of the application server. The security inflow contract enables all activities of a work instance that is submitted by a connector to be performed in the context of an established identity, thus insuring that all interactions between an application server and an EIS/connector are secure, and may prevent unauthorized access to application components deployed in an application server.

A personalized virtual computing system includes a plurality of client personal computers (PCs), each comprising at least a web browser and a communications client, a plurality of virtual machine hosts each comprising a communications server for communicating with the client PCs via said communications client, a web server comprising a client-customized web site, a directory database including identification information of authorized users and a database including a reservation table.

Session management can be supported in a distributed transactional service system using a distributed transactional server and an affinity client. The affinity client operates to receive a service request from a user application and invoke at least one distributed transactional service provided by the distributed transactional server. The distributed transactional server operates to create and maintain a session for the user application when the at least one distributed transactional service is invoked, and the distributed transactional server further operates to determine an affinity scope associated with the session. The affinity scope, which is maintained on the affinity client, defines a routing scope within the distributed transactional service system, into which consequent requests in the session from the user application are dispatched.

A computer-implemented method is disclosed for providing a user with a consistent view of user session in a distributed environment. The method includes providing application servers with data storage means for storing part of the user context for that user session, defining thereby for each user session a set of application servers having each an affinity with the user session. Each application server is configured to process a software application that is required for that user session. At a routing means, performing the following steps with at least one data processor: receiving request from the user and routing transactions of the user session toward the application servers having an affinity with the user session in order to fulfill the request, assigning to the user session a correlation record (DCX) arranged to include Affinity Keys, each Affinity Key indicating an application server that has an affinity with the user session for a given software application, propagating the correlation record with transactions, allowing thereby the routing means to target the application servers that are linked to the user context of that user session and that process the software application relevant to process the transaction.
摘要:
A mechanism for enabling session information to be shared across multiple processes in a multi-process environment is disclosed. There is provided a shared persistent memory-mapped file in a file system, which is mapped to the memory space of each of the processes. This file is used by all of the processes to store session information. Because the memory space of each process is mapped to the shared file, each process is able to access and manipulate all of the sessions in the system. Thus, sessions are no longer maintained on a process-specific basis. Rather, they are maintained on a centralized, shared basis. As a result, different requests pertaining to the same session may be serviced by different server processes without any adverse effects. Each process will be able to access and manipulate all of the state information pertaining to that session. By enabling session information to be shared, this mechanism eliminates the session management errors experienced by the prior art.
摘要:
A method, and corresponding system and software, is described for writing data to a plurality of queues, each portion of the data being written to a corresponding one of the queues. The method includes, without requiring concurrent locking of more than one queue, determining if a space is available in each queue for writing a corresponding portion of the data, and if available, reserving the spaces in the queues. The method includes writing each portion of the data to a corresponding one of the queues.
