A distributed data processing system provides a virtual workplace environment. The virtual workplace environment may be a three-dimensional model of an office, a conference room, or an entire office building complex. Participants are represented by three-dimensional avatars, which move within the virtual environment. Participants may also share data within the virtual environment. Two-dimensional data may be projected onto the surface of a three-dimensional object within the environment, such as a wall. Three-dimensional data may be rendered within the environment for the participants to inspect.

A method and a computer program product are disclosed for tracing the execution path through complex distributed applications in an n-tier client / server distributed computing environment over LAN, WAN, wireless, or the Internet. The system enables quick and pinpointed location of applications and application components along the execution path while consuming only minimal system resources. A tracing token is generated and passed from application component to application component, triggering the collection and recording of identification, timing and application data at each stage of the execution path. The tracing action may be automatically activated by the detection of some system event (such as a slow response to user requests) or be controlled manually by a system operator. The recorded data can be used to considerably speed up application analysis and problem troubleshooting.

A method, computer program product, and distributed data processing system for modifying one or more virtual resources that reside within a physical adapter, such as a peripheral component interconnect (PCI), PCI-X, or PCI-E adapter, and that are associated with a virtual host is provided. Specifically, the present invention is directed to a mechanism for sharing conventional PCI I / O adapters, PCI-X I / O Adapters, PCI-Express I / O adapters, and, in general, any I / O adapter that uses a memory mapped I / O interface for host to adapter communications. A mechanism is provided for directly modifying one or more virtual resources that reside within a physical adapter, such as a PCI, PCI-X, or PCI-E adapter, and that are associated with a virtual host.

A method, system, and computer program product is presented for restricting access to a set of resources in a distributed data processing system. A server determines a set of authorized resources for which a user is authorized to access; the set of authorized resources is a subset of the set of resources that are operational within the distributed data processing system. An evaluation is made about the availability of the set of authorized resources based upon state information about the set of authorized resources. A list of a set of entitled resources for the user is then generated; the set of entitled resources is a subset of the set of authorized resources. An indication of the set of entitled resources may be sent to the user, after which the system would respond to requests for the user to access the set of entitled resources.

A method, computer program product, and distributed data processing system for directly sharing an I / O adapter that directly supports adapter virtualization and does not require an LPAR manager or other intermediary to be invoked on every I / O transaction is provided. The present invention also provides a method, computer program product, and distributed data processing system for directly creating and initializing a virtual adapter and associated resources on a physical adapter, such as a PCI, PCI-X, or PCI-E adapter. Specifically, the present invention is directed to a mechanism for sharing conventional PCI (Peripheral Component Interconnect) I / O adapters, PCI-X I / O adapters, PCI-Express I / O adapters, and, in general, any I / O adapter that uses a memory mapped I / O interface for communications. A mechanism is provided for directly creating and initializing a virtual adapter and associated resources within a physical adapter, such as a PCI, PCI-X, or PCI-E adapter. Additionally, each virtual adapter has an associated set of host side resources, such as memory addresses and interrupt levels, and adapter side resources, such as adapter memory addresses and processing queues, and each virtual adapter is isolated from accessing the host side resources and adapter resources that belong to another virtual or physical adapter.
