摘要： Reducing contentions between processes or tasks that are trying to access shared resources is described herein. According to embodiments of the invention, a method of writing a set of data associated with a task to a memory resource is provided. The method includes calculating the amount of memory required to write said data to the memory resource and updating an expected end marker to reflect the amount of memory required to write the data to the memory resource. A flag is then set to an incomplete state, and the data is written to the memory resource. The flag can be set to a complete state and an end marker is updated. The end marker indicates the end of the data stored in the memory resource.

摘要： A system controller includes an output unit which transfers an access request from an access source coupled to the system controller to an other system controller; a local snoop control unit that determines whether a destination of the access request from the access source is a local memory unit coupled to the system controller, and locks the destination when the destination is the local memory unit; a receiving unit which receives the access request from the output unit and an access request from an other system controller; a global snoop control unit which sends a response indicating whether the access request is executable or not, and controls locking of the destination of the access request when the destination is the local memory unit; and an access processing unit which unlocks the locking and accesses the memory unit when the access request from the access source becomes executable.

摘要： Methods and systems for utilizing a database are disclosed. The methods and systems determine a key representative of a storage location of first RDF data in a NoSQL database. In addition, the methods and systems read the first RDF data in the NoSQL database using the key. The methods and systems also write second RDF data derived from the first RDF data into a second database stored in memory. The methods and systems may also modify the second RDF data, and write third RDF data derived from the modified second RDF data into the NoSQL database.

摘要： Multiple computers are connected to a data storage unit that includes a file system, which further includes multiple data entities, including files, directories and the file system itself. The file system also includes, for each data entity, an owner field for indicating which computer, if any, has exclusive or shared access to the data entity, along with a time field for indicating when a lease of the data entity began. When a computer wants to lease a data entity, the computer uses a disk reservation capability to temporarily lock the data storage unit, and, if the data entity is not currently leased, the computer writes its own identification value into the owner field and a current time into the time field for the data entity, to claim the data entity for a renewable lease period. If a prior lease of a data entity has expired, another computer may break the lease and claim ownership for itself.
摘要翻译：多个计算机连接到包括文件系统的数据存储单元，该文件系统还包括多个数据实体，包括文件，目录和文件系统本身。文件系统还包括用于每个数据实体的所有者字段，用于指示哪个计算机（如果有的话）具有对数据实体的独占或共享访问，以及用于指示何时开始数据实体的租约的时间字段。当计算机要租用数据实体时，计算机使用磁盘预留能力临时锁定数据存储单元，并且如果数据实体当前没有租用，则计算机将自己的标识值写入所有者字段，并且当前时间进入数据实体的时间段，要求数据实体进行可再生租赁期。如果数据实体的先前租赁已经过期，则另一台计算机可能会破坏租赁并为其自行申请所有权。

摘要： The present disclosure describes methods, systems, and computer program products for sharing business data across networked applications. The method for sharing business data across networked applications can include receiving a request associated with data object instance via a first business application. The data object instance is of a specific data object type. A second business application is identified as an assigned master business application associated with the requested data object instance. The first business application and the second business application are based on a common application platform. Data associated with the requested data object instance is accessed at the second business application.

摘要： In one embodiment the present invention includes a computer-implemented for determining whether or not a data object is frozen. The method comprises accessing, by a user on a computer, a first data object of a plurality of data objects in one or more computer software applications. The plurality of data objects are assigned to a plurality of entities, where each entity specifies a category, and each of the plurality of data objects belong to a specific entity. The method determines if the first data object is frozen based on a relationship between the first entity and a second entity.

摘要： A method and apparatus for managing shared resources in a clustered database management system is provided. In an embodiment, multiple master nodes exist in a database management system. A master node receives a lock request from a second node. The lock request is a request for a lock on a shared resource. The master node grants the lock request to the second node. While the second node holds the lock, the second node causes the master node to modify the shared resource.
