摘要： Roll back strategies for database deadlock resolution are customized by identifying a first transaction to a database, identifying a second transaction to the database and detecting a deadlock between the first and second transactions with respect to the database. The deadlock is resolved based upon a predetermined roll back strategy associated with at least one of the first or second transactions to identify a select one of the first and second transactions for roll back and a request is conveyed to roll back the selected one of the first and second transactions, wherein the preferred transaction is allowed to continue processing.

摘要： Embodiments of the present invention provide a method, system and computer program product for enforcing performance goals in an n-Tier distributed caching infrastructure. In an embodiment of the invention, a method of enforcing performance goals in an n-Tier distributed caching infrastructure can include establishing a communicative connection to multiple different cache servers arranged in respective tier nodes in an n-Tier cache. The method also can include collecting performance metrics for each of the cache servers in the respective tier nodes of the n-Tier cache and identifying a cache server amongst the cache servers in respective tier nodes of the n-Tier demonstrating a performance likely to breach at least one term of an SLA. Finally, the method can include applying a remedial measure to the identified cache server.

摘要： Systems and methods of managing an in-memory data grid (IMDG) may involve conducting a data distribution analysis of the IMDG on a periodic basis, and selecting a hash scheme from a plurality of hash schemes based on the data distribution analysis. In one example, the selected hash scheme is used to conduct a repopulation of the IMDG, wherein the repopulation increases the distribution evenness of database records across the IMDG.

摘要： A TTL value for a data object stored in-memory in a data grid is dynamically adjusted. A stale data tolerance policy is set. Low toleration for staleness would mean that eviction is certain, no matter the cost, and high toleration would mean that the TTL value would be set based on total cost. Metrics to report a cost to re-create and re-store the data object are calculated, and the TTL value is adjusted based on calculated metrics. Further factors, such as, cleanup time to evict data from a storage site, may be considered in the total cost.
摘要翻译： 动态调整数据网格中存储在内存中的数据对象的TTL值。 设置过时的数据容错策略。 低容忍的陈旧意味着驱逐是确定的，无论成本高，耐受度高都意味着TTL值将根据总成本设定。 计算报告重新创建和重新存储数据对象的成本的指标，并根据计算的指标调整TTL值。 可能会考虑其他因素，例如从存储站点驱逐数据的清理时间。

摘要： A central configuration server is provided for managing user-specified configuration data for a configurable device. The central configuration server, which is separate from a configurable device to be configured, and which services a plurality of users, obtains a user identification and device information from the configurable device. Responsive to this, the central configuration server accesses an account database and uses the user identification and device information to retrieve, for the identified user, user-specified configuration data for the configurable device. The central configuration server then forwards the user-specified configuration data from the account database to the configurable device for use in automatically configuring the configurable device pursuant to the user-specified configuration data.
