摘要： A database server stores compressed units in data blocks of a database. A table (or data from a plurality of rows thereof) is first compressed into a “compression unit” using any of a wide variety of compression techniques. The compression unit is then stored in one or more data block rows across one or more data blocks. As a result, a single data block row may comprise compressed data for a plurality of table rows, as encoded within the compression unit. Storage of compression units in data blocks maintains compatibility with existing data block-based databases, thus allowing the use of compression units in preexisting databases without modification to the underlying format of the database. The compression units may, for example, co-exist with uncompressed tables. Various techniques allow a database server to optimize access to data in the compression unit, so that the compression is virtually transparent to the user.
摘要翻译：数据库服务器将压缩单位存储在数据库的数据块中。使用各种各样的压缩技术中的任一种，首先将表（或其多行的数据）压缩为“压缩单元”。然后，压缩单元被存储在跨越一个或多个数据块的一个或多个数据块行。结果，单个数据块行可以包括在压缩单元内编码的多个表行的压缩数据。数据块中的压缩单元的存储与现有的基于数据块的数据库保持兼容，从而允许在预先存在的数据库中使用压缩单元，而无需修改数据库的底层格式。压缩单元可以例如与未压缩的表共存。各种技术允许数据库服务器优化对压缩单元中的数据的访问，使得压缩对于用户实际上是透明的。

摘要： A method and apparatus for sharing state information among a plurality of servers is provided. A first server receives a request to perform a file operation, such as a NFS file system operation. Thereafter, the first server updates state information to reflect a change in state associated with processing the request. The first server then causes state update information, which identifies the change in state that was made at the first server, to be propagated to a second server. The second server updates state information, stored at the second server, to reflect the change in state associated with processing the request at the first server. Advantageously, a client may send a series of stateful file operations to either the first server or the second server, even if processing any one of the stateful file operation requests requires knowledge of the state of processing prior requests in the series of requests.
摘要翻译：提供了一种用于在多个服务器之间共享状态信息的方法和装置。第一服务器接收执行诸如NFS文件系统操作之类的文件操作的请求。此后，第一服务器更新状态信息以反映与处理请求相关联的状态变化。然后，第一服务器导致状态更新信息，其标识在第一服务器处进行的状态的改变，以被传播到第二服务器。第二服务器更新存储在第二服务器处的状态信息，以反映与在第一服务器处理请求相关联的状态变化。有利地，客户机可以向第一服务器或第二服务器发送一系列有状态的文件操作，即使处理有状态文件操作请求中的任何一个需要知道在一系列请求中处理先前请求的状态。

摘要： One embodiment of the present invention provides a system that implements a security policy in a database. During operation, the system receives a request associated with a set of objects in the database. Next, the system obtains a set of access control lists (ACLs) associated with the database, wherein a respective ACL specifies one or more access privileges associated with a user or user group, and wherein a respective ACLs is not specific to a particular object in the database. The system then evaluates the ACLs to obtain a set of ACL results associated with the request and processes the request by applying the set of ACL results to the objects without evaluating the ACLs repeatedly for each of the objects.

摘要： The present invention relates to methods and systems of snapshot management of a file system in a data storage system. To represent the snapshots, the invention maintains pointers to the root block pointer of each snapshot. When the active file system is modified, this invention avoids overwriting any blocks used by previous snapshots by allocating new blocks for the modified blocks. When the invention needs to put an established block in a new location, it must update a parent block to point to the new location. The update to the parent block may then require allocating a new block for the new parent block and so forth. Parts of the file system not modified since a snapshot remain in place. The amount of space required to represent snapshots scales with the fraction of the file system that users modify. To maintain snapshot integrity, this invention keeps track of the first and last snapshots that use each block in space map blocks spread throughout the file system data space. When users delete snapshots, this invention may use a background process to find blocks no longer used by any snapshot and makes them available for future use.
摘要翻译：本发明涉及数据存储系统中文件系统的快照管理方法和系统。为了表示快照，本发明保持指向每个快照的根块指针的指针。当活动文件系统被修改时，本发明通过为修改的块分配新的块来避免覆盖先前快照所使用的任何块。当本发明需要将一个已建立的块放在新位置时，它必须更新一个父块以指向新的位置。然后，对父块的更新可能需要为新的父块等分配新块。文件系统的部分因为快照保留到位而未被修改。代表快照所需的空间量会随着用户修改的文件系统的一小部分而缩放。为了保持快照完整性，本发明记录使用遍及文件系统数据空间的空间图块中的每个块的第一个和最后一个快照。当用户删除快照时，本发明可以使用后台进程来查找不再被任何快照使用的块，并使之可供将来使用。

摘要： Techniques are provided for accessing and storing files within a virtual folder. A virtual folder is a folder that is logically a part of a hierarchical folder structure of a file system repository, but the contents of the virtual folder are not physically stored in the file system repository. A client may issue, to an access mechanism, a request to perform a file operation on a file in a virtual folder. The access mechanism, which may be a database server or a component therein, may perform the file operation on the file in the virtual folder as if the file was stored in a particular folder within the hierarchical folder structure implemented by the file system repository. Advantageously, files may be physically stored outside of the file system repository, but still be a part of the hierarchical folder structure implemented by the file system repository.
摘要翻译：提供技术来访问和存储虚拟文件夹中的文件。虚拟文件夹是逻辑上是文件系统存储库的分层文件夹结构的一部分的文件夹，但虚拟文件夹的内容不会物理存储在文件系统存储库中。客户端可以向访问机制发出对虚拟文件夹中的文件执行文件操作的请求。可以是数据库服务器或其中的组件的访问机制可以对虚拟文件夹中的文件执行文件操作，就好像该文件被存储在由文件系统存储库实现的分层文件夹结构内的特定文件夹中。有利地，文件可以物理地存储在文件系统存储库之外，但仍然是由文件系统存储库实现的分层文件夹结构的一部分。

摘要： A properly modulated carrier signal exits transmission circuitry (201) and enters a first and a second mixer (203, 205). The modulated carrier is mixed with a first and a second function by the first and the second mixers (203, 205). The functions are generated by a first and a second signal generator (207, 209). The mixed signals exit the mixers (203, 205), and are amplified (via amplifiers 211-213), to be radiated by an antenna (211). The antenna (221) comprises two orthogonal antenna elements (215, 217), that are in close proximity with one another (although not in contact). One of the mixed signals is radiated on a first element (215), and the other mixed signal is radiated on the second element (217). The resulting signal transmitted from the antenna (221) is the original carrier signal having the plane of polarization constantly changing. Thus a reflected signal emitted an instance earlier cannot interfere with a wave currently emitted.

摘要： Techniques for storing and manipulating tabular data are provided. According to one embodiment, a user may control whether tabular data is stored in row-level or column-major format. Furthermore, the user may control the level of data compression to achieve an optimal balance between query performance and compression ratios. Tabular data from within the same table may be stored in both column-major and row-major format and compressed at different levels. In addition, tabular data can migrate between column-major format and row-major format in response to various events. For example, in response to a request to update or lock a row stored in column-major format, the row may be migrated and subsequently stored into row-major format. In one embodiment, table partitions are used to enhance data compression techniques. For example, compression tests are performed on a representative table partition, and a compression map is generated and applied to other table partitions.
摘要翻译：提供了存储和操作表格数据的技术。根据一个实施例，用户可以控制表格数据是以行主列还是列主格式存储。此外，用户可以控制数据压缩的水平，以实现查询性能和压缩比之间的最佳平衡。来自同一表格的表格数据可以以列主和行主格式存储，并在不同级别进行压缩。此外，响应于各种事件，表格数据可以在列主格式和行主格式之间迁移。例如，响应于更新或锁定以列主格式存储的行的请求，该行可以被迁移并且随后被存储为行主格式。在一个实施例中，表分区用于增强数据压缩技术。例如，压缩测试在代表性的表格分区上执行，生成压缩映射并将其应用于其他表格分区。

摘要： A method and apparatus is provided for optimizing queries received by a database system that relies on an intelligent data storage server to manage storage for the database system. Storing compression units in hybrid columnar format, the storage manager evaluates simple predicates and only returns data blocks containing rows that satisfy those predicates. The returned data blocks are not necessarily stored persistently on disk. That is, the storage manager is not limited to returning disc block images. The hybrid columnar format enables optimizations that provide better performance when processing typical database workloads including both fetching rows by identifier and performing table scans.
摘要翻译：提供了一种方法和装置，用于优化由数据库系统接收的依赖于智能数据存储服务器来管理数据库系统的存储的查询。以混合列格式存储压缩单元，存储管理器将评估简单谓词，并仅返回包含满足这些谓词的行的数据块。返回的数据块不一定存储在磁盘上。也就是说，存储管理器不限于返回盘块图像。混合柱状格式可以实现在处理典型数据库工作负载时提供更好性能的优化，包括通过标识符提取行和执行表扫描。
