摘要： A method and system for recovering from a failure of a processing node in a partitioned shared nothing database processing system are provided. The processing system may include a pair of processing nodes having twin-tailed-connected thereto a storage device. A first processing node of the pair of processing nodes has a first database instance running thereon which accesses a first data partition on the storage device prior to the failure. Upon detection of the failure, access to the first data partition on the storage device is provided to a third, spare processing node through the second processing node of the pair of processing nodes. The third processing node runs a replacement database instance for the first database instance which was running on the first processing node prior to the failure thereof. The replacement database instance accesses the first data partition on the storage device through the second processing node, thereby recovering from the failure of the first processing node. Access to the first data partition may include using a virtual shared disk utility having a server portion on the second processing node and a client portion on the third processing node.

摘要： Identifying traffic patterns to web sites based on templates that characterize the arrival of traffic to the web sites is provided. Based on these templates, determinations are made as to which web sites should be co-located so as to optimize resource allocation. Web sites whose templates are complimentary, i.e. a first web site having a peak in arrival traffic at time t1 and a second web site that has a trough in arrival traffic at time t1, are designated as being candidates for co-location. In addition, the templates identified for the traffic patterns of web sites are used to determine thresholds for offloading traffic to other servers. These thresholds include a first threshold at which offloading should be performed, a second threshold that takes into consideration the lead time needed to begin offloading, and a third threshold that takes into consideration a lag time needed to stop offloading of traffic.

摘要： A method, apparatus, and computer implemented instructions for generating a customized catalog for an entity or organization. Items from a base catalog are presented to a user located at a remote data processing system. One or more items are selected by a user through a process of “meta-shopping”. The selected items are placed in a set, also referred to as a “meta-shopping cart”, used to generate the customized catalog. Terms for purchasing items in the customized catalog are associated with the customized catalog. Further, a protocol for purchasing items from the customized catalog may be established, and the customized catalog is then placed on a Web site.

摘要： Techniques are disclosed for network distribution and provisioning of applications, such as transactional applications and parallel applications, across multiple administrative domains that ensure compliance with service level agreements. For example, a method of provisioning one or more resources in a distributed computing network to ensure compliance with a service level agreement associated with a computer application includes the following steps. Network performance is monitored between a local domain and one or more cooperating domains connected to the local domain by network paths. A present or predicted violation of the service level agreement is identified based on at least a portion of results of the monitoring step. One or more cooperating domains are selected that can effect compliance with the service level agreement by instantiating one or more network resources within at least one of the selected cooperating domains in response to a request from the local domain. Reconfiguration of the local domain is effectuated to allow the computer application to make use of the one or more newly instantiated network resources within the selected cooperating domain.

摘要： A clustered computer system includes a shared data storage system, preferably a virtual shared disk (VSD) memory system, to which the computers in the cluster write data and from which the computers read data, using data access requests. The data access requests can be associated with deadlines, and individual storage devices in the shared storage system satisfy competing requests based on the deadlines of the requests. The deadlines can be updated and requests can be killed, to facilitate real time data access for, e.g., multimedia applications such as video on demand.

摘要： A method and system are provided for partitioning a database and for balancing the processing load among processing nodes in a data processing system. A database partition is stored at each node and a logical owner node is assigned to each partition. The logical owner becomes responsible for all database requests related to the corresponding partition. Techniques for optimally assigning logical owners to all partitions in a system are provided and are responsive to parameters such as the load at each node, the combined load of the system, and the total number of assignments allowed. Techniques are also provided to accomplish the transfer of partition ownership between processing nodes when multiple transactions related to the partition are simultaneously occurring.
