摘要： Process reflection techniques are described in which a reflected process is created to facilitate analysis of a process. Events are detected to initiate reflection of a target process. Process reflection of a target process may be initiated by an external process or by the target process itself. A reflected process of the target process is created. In an implementation, data defining the target process is replicated, copied, or otherwise collected from the target process to create the reflected process. Then, analysis may be performed on the reflected process while execution of the target process continues.

摘要： The resource leak detector attempts to identify the causes of resource leaks and fix the causes if possible. At a minimum, the located resource leaks are reported to an operating system manufacture for additional study and possible correction, either by the operating system manufacturer or the application manufacturer that is causing the resource leak.

摘要： The resource leak detector attempts to identify the causes of resource leaks and fix the causes if possible. At a minimum, the located resource leaks are reported to an operating system manufacture for additional study and possible correction, either by the operating system manufacturer or the application manufacturer that is causing the resource leak. In an embodiment, in operation, a leak trigger for starting leak detection is started. If the leak trigger is activated, leak detection is started when an application begins. Resource allocations are tracked for the leaked resource and each leaked resource is matched to a corresponding allocation call stack. A type of the leaked resource may be identified. The leak detection and the leak trigger may be controlled according to at least one of a local policy and a global policy. The local and the global policy may be updated dynamically such as by using aggregated occurrences of applications that met the local policy or by matching a plurality of distinct types of leaked resources to the same call stack. A leak report may be generated of resource leak data where the leak report is stored locally or communicated to a local aggregation database or remote aggregation database. The leak report may include total leaked allocations, total size of leaked allocations, total outstanding allocations, total size of outstanding allocations and matched allocation call stacks. The leaked resource may be automatically reclaimed and a fix to the leaked resource may be created and applied automatically.

摘要： A technique fulfills service requests in a system of computers that communicate as nodes within a network. The technique involves sending, in response to an initial service request that requests a service provided by a primary server node, a mobile agent from the primary server node to an intermediate node. The mobile agent indicates to the intermediate node that a secondary server node is capable of providing the service. The technique further involves intercepting, at the intermediate node, a subsequent service request sent from a client node to the primary server node, the subsequent service request requesting the service, and sending an instruction from the intermediate node to the secondary server node. The instruction instructs the secondary server node to provide the service. The technique further includes providing, in response to the instruction, the service from the secondary server node to the client node.

摘要： A technique for automatic, transparent, distributed, scalable and robust replication of document copies in a computer network wherein request messages for a particular document follow paths from the clients to a home server that form a routing graph. Client request messages are routed up the graph towards the home server as would normally occur in the absence of caching. However, cache servers are located along the route, and may intercept requests if they can be serviced. In order to be able to service requests in this manner without departing from standard network protocols, the cache server needs to be able to insert a packet filter into the router associated with it, and needs also to proxy for the home server from the perspective of the client. Cache servers cooperate to update cache content by communicating with neighboring caches whenever information is received about invalid cache copies.

摘要： A technique for automatic, transparent, distributed, scalable and robust caching, prefetching, and replication in a computer network that request messages for a particular document follow paths from the clients to a home server that form a routing graph. Client request messages are routed up the graph towards the home server as would normally occur in the absence of caching. However, cache servers are located along the route, and may intercept requests if they can be serviced. In order to be able to service requests in this manner without departing from standard network protocols, the cache server needs to be able to insert a packet filter into the router associated with it, and needs also to proxy for the home server from the perspective of the client. Cache servers may cooperate to service client requests by caching and discarding documents based on its local load, the load on its neighboring caches, attached communication path load, and on document popularity. The cache servers can also implement security schemes and other document transformation features.
