摘要： The present invention relates to a system and methodology to facilitate interoperability and compatibility between disparate data systems. In one aspect, a file transformation system is provided having at least one file associated with one or more unstructured properties. A file property handler manipulates the unstructured properties in accordance with one or more structured properties associated with a structured object store environment. If an unstructured file is to be operated in the context of a structured object store environment, a promotion operation is performed to update unstructured properties in the file with structured properties suitable for operation in the structured object store environment. If a promoted item were to be manipulated in the structured object store environment, a demotion operation or reverse transformation is performed to update properties in the file.

摘要： System and method for virtual data warehouses having table link capabilities are provided. In particular, some embodiments include a plurality of virtual data warehouses built on top of a data center running Apache Hive. Each virtual data warehouse can be modeled as a database and manage data in forms of database tables. The virtual data warehouse can include links which import tables from other virtual data warehouses by reference. Each link may contain partition metadata for the table partitions by dates of the source table and retention metadata to declare the needed retention time period for the partitions of the source table. The links can be dynamic and update when the corresponding source table receives new partitions or drops partitions. When a virtual data warehouse is migrated to another data center, the system can retain necessary table partitions to remain on the current data center based on the partition metadata and retention metadata of the links.

摘要： Rich structured data for items in a file system that allows different kinds of data to be identified by metadata is mapped into a set of search properties for a desktop search service, which is a flat list. This is applicable to any rich structured data that should be mapped into search properties for a desktop search service. Included is an installation mechanism to install these mappings and an execution infrastructure for utilizing the generated SQL from the mappings to extract search properties from items.

摘要： A method to identify a child process to a parent process in an operating system includes obtaining a token and login identifier from the operating system. The parent process creates a remote procedure call communications endpoint to communicate with the child process. Thereafter, a child process is spawned by the parent process. A child-initiated request to communicate with the parent process is then received by the parent process. In order to verify the identity of the child-initiated request, the parent process impersonates the child process and receives as identifier that identifies the requestor child process. The requestor process identifier and the spawned child identifier are compared. Based on the comparison, the parent process responds to the child-initiated request. In another embodiment, process identifiers are used by the parent process to verify the identity of a child process the requests communication with the parent process.

摘要： An arbitration policy resolves software applications operating on a single unit of data in a manner conflicting with other applications that operates on the same data or properties of the data. This is accomplished through picking an entity type of one application to have priority over an entity type of another application when both entity types map to a same property which caused the conflict. This allows user to observe the data in a consistent manner when switching between applications.

摘要： Techniques for determining effects, on a system, of values for a parameter that is used to manage memory for the system include generating data that indicates a workload and an actual performance of the system. The data is generated while processing the workload within the system using a first value for the parameter. Based on the data, an estimated performance is generated. The estimated performance is a performance that the system would have experienced if a second value for the parameter had been used to process the workload. The second value is different from the first value for the parameter. Using these techniques, an administrator can determine what change in system performance could be achieved by changing a value of the memory management parameter. Therefore the system administrator can better determine whether to make the change in the value of the memory management parameter.
摘要翻译：用于确定系统对用于管理系统的存储器的参数的值的影响的技术包括生成指示系统的工作负载和实际性能的数据。在使用参数的第一个值处理系统内的工作负载时生成数据。基于该数据，产生估计的性能。如果参数的第二个值已被用于处理工作负载，则估计的性能是系统将遇到的性能。第二个值与参数的第一个值不同。使用这些技术，管理员可以通过更改内存管理参数的值来确定可以实现系统性能的改变。因此，系统管理员可以更好地确定是否对内存管理参数的值进行更改。
