摘要： In order to provide recovery for a database stored on storage not meeting the WAL protocol requirements, for example, storage including a temporary cache and a second storage (e.g. an IDE disk with a temporary cache and a hard disk), a log is created including, for each changed page, a pre-image of the page before changes were effected. The log also includes one or more change log records logging changes made to the page. Periodic checkpoints occur in which the cached pages are flushed to the disk. Recovery proceeds with a redo pass through the active log and then with an undo pass, undoing any transactions that have not been committed.

摘要： In order to provide a more efficient persistent storage device, one or more long-term storage media are included along with a non-volatile memory. In one embodiment, one portion of the non-volatile memory is used as a write buffer and a read cache for writes and reads to the long-term storage media. Interfaces are provided for controlling the use of the non-volatile memory as a write buffer and a read cache. Additionally, a portion of the non-volatile memory is used to provide a direct mapping for specified sectors of the long-term storage media. Descriptive data regarding the persistent storage device is stored in another portion of the non-volatile memory.

摘要： Systems and methods are disclosed that facilitate providing page-level database restore functionality upon detection of a corruption event. Updates to a data page in a database can trigger generation of a snapshot of the data page, and an update log can be maintained that stores information related to page updates. Subsequent snapshots can be generated at predetermined intervals and can trigger truncation of a log segment and initiation of a new log segment. Upon detection of page corruption, a most-recent uncorrupt snapshot of the corrupt page can be identified, copied to the location of the corrupt page in the database, and modified according to the log segment associated with the uncorrupt snapshot to make the page current as of the corrupting event, all of which can be performed to restore the database without having to take the database offline.

摘要： A method and system for fragment-based serialization places one or more object members in fragments. Fragments may comprise a header and a payload. A header can provide useful information about the fragment, such as an indication of fragment type and an indication of fragment length. A payload may comprise one or more members of an object. Primitive members may be stored in a Binary Fragment with a record format payload. LOB and FS members may be stored in fragments that have a Value Type field for setting forth additional properties of the fragment. Collections may be stored in a series of fragments, a first fragment to indicate a start of a collection, one or more second fragments to serialize collection elements, and a Terminator Fragment to indicate the end of a collection. Fragment-serialized objects minimize storage overhead while providing fast instantiation and low-cost location and updating.
摘要翻译： 用于基于片段的序列化的方法和系统将一个或多个对象成员放置在片段中。 片段可以包括报头和有效载荷。 头可以提供关于片段的有用信息，例如片段类型的指示和片段长度的指示。 有效载荷可以包括对象的一个或多个成员。 原始成员可以存储在具有记录格式有效载荷的二进制片段中。 LOB和FS成员可以存储在具有值类型字段的片段中，用于设置片段的附加属性。 集合可以存储在一系列片段中，第一片段指示集合的开始，用于序列化集合元素的一个或多个第二片段以及用于指示集合结束的终止符片段。 片段序列化的对象可以最大限度地减少存储开销，同时提供快速实例化和低成本的位置和更新。

摘要： A method for performing a consistency check on a database backup of a database is performed without requiring a full recovery of the original database from the database backup. Instead, a database view may be used as a smaller storage requirement tool for providing a transaction-consistent view of portions of an existing full database backup. The database view, in combination with the database backup and transaction log, contains all the information necessary to perform a consistency check on the database backup without a full reconstitution of the original database from the database backup. The consistency check may be run on the database view along with the database backup to verify the integrity of the full database backup to add improved reliability to a database recovery scheme.

摘要： A system and method for controlling usage of a particular software program in a computer network environment is disclosed. The invention operates by controlling the throughput of the software as it executes on a server computer. In particular, the invention monitors the number of active requests to the software. If the number of active requests exceeds a predefined number, the software throughput on the server (e.g., requests completed per minute) is artificially restricted. As such, the present invention continues to allow further connections to the software but intentionally restricts further use by inhibiting the throughput for all connections to the software. Preferably, the present invention continues to allow the predefined number of active requests to be exceeded, but as more requests are made, the overall performance of software progressively degrades.

摘要： A method for equipping bottles with equipment elements using a group of at least three similar container-equipping subassemblies designed to apply equipment elements to a container region of containers moving, on a transporting system, past the container-equipping subassemblies includes, during disruption-free operation, activating at least two container-equipping subassemblies of the group to equip in each case one container that has not yet been labeled by another container-equipping subassembly of the group, and during disruption-free operation, placing at least one container-equipping subassembly assigned to the group in standby mode, and in the event of disruption to a first activated container-equipping subassembly in the group, activating the container-equipping subassembly that is in standby mode to take over the function of the first container-equipping subassembly.

摘要： A system and method for accelerating searches of B-trees. An auxiliary index that is optimized for use with a cache is used in conjunction with a B-tree. A hash type of auxiliary index maintains pointers to key entries in the B-tree leaf nodes. The hash type of index may be searched, and a resulting pointer is used to locate records of the B-tree, bypassing a search of the B-tree. A top level type of auxiliary index maintains pointers to leaf nodes or internal nodes of the B-tree. A top level index may be searched, and a search of the B-tree is performed beginning with the node found by using the top level index. A monitoring mechanism may automatically start, change, or discard the auxiliary index based on an amount of cache memory, types of searches, or other factors. The auxiliary index may be optimized for high performance in read only searches, while the B-tree provides transaction durability.
