摘要:
A method, computer program product and network management server for distributing software. The network management server receives a request to deploy an application on a designated target client station at a designated scheduled time. The network management server determines whether to deploy the application on the designated target client station at the designated time based on the resource state of the systems involved in the deployment of the software (e.g., processor usage of the network management server, processor usage of the target client station) as well as the environmental conditions (e.g., bandwidth usage, time of day pricing for connectivity at scheduled time, work orders on the target client station). By taking into consideration the dynamic resource state of the systems involved in the deployment of the software as well as the environmental conditions, software may be deployed on the client stations by the network management server more effectively.

A computing services grid. The grid can include a service desk coupled to one or more computing service instances. Each service instance can conform to an interface which is common to all service instances in the grid. A routing component can be disposed in the grid. Specifically, the routing component can route individual service requests to individual ones of the service instances. An instance selection service is used to satisfy QoS characteristics associated with the requester of the service. The grid further can include a service instance monitoring component. The monitoring component can monitor the performance of individual service instances charged with processing individual service requests. Fail-over logic can be configured to re-route service requests from selected service instances to others of the service instances where the monitoring component detects a fail-over condition in the selected service instances. In that regard, fail-over conditions can include error conditions and a performance deficiency conditions in which the performance of a selected service instance lags behind guaranteed levels of performance.

A method, apparatus, and computer program product for managing a workload in a hybrid cloud. It is determined whether first data processing resources processing a portion of a workload are overloaded. Responsive to a determination that the first data processing resources are overloaded, second data processing resources are automatically provisioned and the portion of the workload is automatically moved to the second data processing resources for processing. The second data processing resources are data processing resources that are provided as a service on the hybrid cloud. Processing of a first portion of a workload being processed on first data processing resources of a hybrid cloud are monitored simultaneously with monitoring processing of a second portion of the workload being processed on second data processing resources of the hybrid cloud. The workload may be allocated automatically between the first portion and the second portion responsive to the simultaneous monitoring.
摘要:
Management of the processing of relatively large data objects in a communications stack having multiple layers improves the performance in a communications system in preparing relatively large data objects for transmission across a communications network. This reduces or eliminates data movement and copying during segmentation of the relatively large data objects into relatively small data objects, and appendage of headers to the relatively small data object segments during processing in the communications stack. A shared storage manager creates and controls multiple tokens representing multiple images of portions of the relatively large data objects to enable separate scheduling of the multiple images from the same storage unit or buffer to be passed from one layer in a communications stack to the next lower layer in the communications stack. The large data object is segmented into a plurality of relatively small data object segments at one or more of the layers in the communications stack. When dictated by the communications stack, header segments are also created for each relatively small data object segment. Each header segment contains specific information for the relatively small data object segment to which the header corresponds. A separate buffer list is generated by the communications stack for each relatively small data object segment and for each corresponding header segment.

Data transfer from an application at a node of a network to a queue for a data channel is disabled when the amount of queued data in the queue is greater than a first limit and enabled when the amount of queued data in the queue is less than a second limit. The first queue limit preferably is increased when data transfer is disabled and the amount of queued data in the queue is less than the buffer storage capacity and decreased when data transfer is enabled and the data flow rate of the data channel is decreased. The second queue limit preferably is increased when data transfer is enabled and the amount of queued data in the queue is less than a predetermined data channel starvation threshold and decreased if, after data transfer from the application to the queue becomes enabled and an amount of queued data the same as the second queue limit has been communicated from the queue to the data channel, the amount of queued data in the queue is greater than a predetermined threshold. Preferably, the limits include an integral multiple of the predetermined amount of data in a burst, and are increased and decreased by an integral multiple of the predetermined amount of data in a burst. In response to a decrease in the available global storage capacity, the first and second queue limits may be reduced by first and second predetermined amounts, respectively, the first and second predetermined amounts preferably being the same.

A problem determination method, system and program product are provided. Specifically, the present invention identifies problems with software programs by inserting compiled problem determination probes into program classes while the computer system on which the program is loaded is running. Once the probes have been inserted, the classes will be run and trace data will be generated. The trace data can be retrieved and analyzed to identify and address the problem. When the probes are no longer needed, they can be removed while the computer system continues to run.

A dedicated processor for efficient processing of documents encoded in a markup language, such as XML. The dedicated processor is capable of performing traditional parsing, transformation and manipulation processes on the document. The special purpose processor frees a general purpose processor to perform other tasks, resulting in an increase in system performance. In one embodiment, the dedicated processor includes a general purpose processor and suitable software which is provided in addition to the general purpose processor which has been traditionally used for processing. In such an embodiment, the dedicated processor may be implemented in a multi-processor system. In another embodiment, the dedicated processor is implemented in special purpose hardware, e.g. as an integrated circuit embodied in silicon in one or more chips. In either embodiment, the dedicated processor may be provided to offload processing locally or remotely.
摘要:
Effective memory management maximizes the use of main memory in a computing system by avoiding the issuance of operating system primitives which result in overhead and increased processing time. This allows an applications program to change the state of a storage unit such as a buffer or page without requiring the issuance of an operating system primitive to change the physical state of the storage unit. A storage manager is provided for controlling the movement of data between storage units in secondary storage and storage units in main memory. A storage unit state indicator or flag is associated with each storage unit in main memory. In addition, a system state indicator for indicating the physical state of a storage unit is also associated with each storage unit. The system state indicator may be set to one of the states of fixed or pageable while the storage unit state indicator may be set to one of the states of fixed, pageable or don't care. The storage manager monitors the usage of memory to determine whether a fixed storage constraint may occur. Upon a determination that a fixed storage constraint may occur, the storage manager notifies the applications programs of the fixed storage constraint. In response, applications programs can temporarily change the state of a storage unit containing data which temporarily may not be needed by the applications program from fixed to don't care by changing the storage unit state indicator from fixed to don't care. Thus, the storage unit is available to the storage manager if needed without the need to have the storage manager issue an operating system primitive to change the system state indicator for the storage unit from fixed to pageable.
