摘要： The present invention extends to methods, systems, and computer program products for partitioning online databases. Online database operations, such as, for example, SPLIT, MERGE, and DROP, are used to alter the arrangement of partitions in a federated database. A SPLIT operation splits rows at one partition across a plurality of other partitions. A MERGE operation merges rows at a plurality of partitions in to one partition. A DROP operation shifts responsibility for rows of data from one partition to another partition and then drops the rows from the one partition.

摘要： The present invention extends to methods, systems, and computer program products for scoping the context used to access a database partition. Embodiments of the invention enable data isolation using partitions in multi-tenant databases, while relieving client applications from dealing with the partitions. For example, a computer system that includes a distributed database system comprising a plurality of database partitions in a federation receives a context to use when performing database access operations within the distributed database system. The context identifies specified relevant portion of the federation. The computer system also receives a database access operation that is associated with the context. The computer system modifies the semantics of the database access operation in accordance with the associated context, to direct application of the database access operation to the specified relevant portion of the federation.

摘要： There is described a process for the synthesis of a sucrose-6-ester comprising: (a) reacting a mixture comprising sucrose and a polar aprotic solvent with an organotin-based acylation promoter, while adding a solvent capable of removing water by co-distillation, and removing water by co-distillation, to afford a first reaction mixture which is substantially free from water, followed by (b) adding a carboxylic anhydride to said first reaction mixture to afford a second reaction mixture, and maintaining said second reaction mixture at a temperature and for a period of time sufficient to produce a sucrose-6-ester, characterised in that step (a) is performed at a temperature of from 85 to 125° C. and at a pressure of from 20 to 80 kPa. In the most preferred embodiment, the polar aprotic solvent is DMF, the solvent capable of removing water by co-distillation is cyclohexane, the organotion-based acylation promoter is a 1,3-diacyloxy-1,1,3,3-tetrabutyldistannoxane, and step (a) is performed at approximately 97° C., and approximately 50 kpa, until the weight ratio of tin to water in the first reaction mixture is greater than about 26, when the tin content is measured by X-Ray Fluoresence Analyzer, and the water content is measured by the Karl-Fischer method.

摘要： Thread usage is managed when locking resources during the possibly-contentious accessing of such resources. In a described implementation, a thread that is executing a corresponding access request is not suspended when its corresponding access request is delayed because a targeted resource is currently locked for accessing by another thread. Instead, when a targeted resource is locked, the blocked access request is queued up in a queue of access requests. The corresponding thread is then permitted to perform other work. When the resource is subsequently unlocked and thus becomes available, an access request (e.g., the oldest or highest priority access request) that is queued is retrieved, and a thread is allowed to execute it. Implementations for general locking access schemes, for read/write-bifurcated locking access schemes, etc. are described. Implementations are described from conceptual, functional, temporal, code or function, contention, thread, and other perspectives.
摘要翻译：在可能争取访问这些资源的过程中锁定资源时，会管理线程使用。在描述的实现中，当对应的访问请求被延迟时，正在执行相应的访问请求的线程不被暂停，因为目标资源当前被锁定以被另一个线程访问。相反，当目标资源被锁定时，阻塞的访问请求在访问请求队列中排队。然后允许相应的线程执行其他工作。当资源随后解锁并因此变得可用时，检索排队的访问请求（例如，最早或最高优先级的访问请求），并允许线程执行它。描述了用于读/写分叉锁定访问方案的通用锁定访问方案的实现等。实现从概念，功能，时间，代码或功能，争用，线程和其他角度进行描述。

摘要： A database development system is provided. The system includes a current-state source representation of a database that can be captured in a model of the database and a metadata component that preserves user intentions describing when a user interacts with the system to perform a refactoring operation (or other code enhancement) for use in subsequent operations by the system. A deployment component is provided that utilizes the preserved user intentions to optimize behavioral upgrades to the system, where simulations can be run against the model to facilitate efficient and automated deployments.
