摘要： A system for retrieving stored data and/or index pages, receives a database request, generates an access plan for the database request for accessing data rows and/or index entries according to the statement, and generates a priming process by selecting a set of data and/or index pages. The set of data and/or index pages is a super-set or the exact set of the pages needed for accessing data rows and/or index entries according to the access plan. The present system retrieves the data and/or index pages of the set before executing the database request according to the access plan. The execution of the database request is performed by scanning the index and data pages preloaded into the cache. This reduces the number of necessary disk reads during execution.

摘要： According to the method for establishing a log point an information technology infrastructure is provided. Transactions are performed by at least two database units of the information technology infrastructure. Then, “suspending prepare to commit”-requests are sent from said coordinating device to said database units. The log writes of all database units are suspended and recorded, whereas these log points form a global log point. Finally the log writes of all database units and all the suspended transactions are resumed.

摘要： The present system indexes a plurality of entries in a database that contains a database table having a base index. As a recent row is inserted in the database table, an index increment is generated based on the inserted row. Preferably, the index increment is smaller in size than the base index because it is recently generated. The smaller size of the index increment facilitates the management of the index increment. An index entry associated with the inserted row is added to the index increment, and the index increment is merged with the base index.
摘要翻译：本系统对包含具有基本索引的数据库表的数据库中的多个条目进行索引。由于最近一行插入到数据库表中，所以根据插入的行生成索引增量。优选地，索引增量的大小比基本索引更小，因为它最近被生成。索引增量的较小尺寸有助于指数增量的管理。与插入行相关联的索引条目被添加到索引增量中，索引增量与基本索引合并。

摘要： Methods and apparatus, including computer program products, for maintaining a set of indexes in a database management system (DBMS) having at least one table. A current, stale or deferred status is defined for at least a part of the indexes, resulting in at least a part of a set of current, stale, or deferred indexes in the DBMS. Current indexes are maintained by refreshing a current index synchronously with a table change relating to the current index. Stale indexes are maintained by refreshing a stale index continuously and asynchronously to table modifications of tables relating to the stale index based on log information relating to the modifications. Deferred indexes are maintained by building a deferred index in response to a query to a table relating to the deferred index, thereby bringing the deferred index in accordance with the current query time status to the table relating to the deferred index.

摘要： According to an embodiment of the present invention, a method for reorganizing a source index tree of a database table resulting in a target index tree of the database table is provided. A backup process reads source leaf pages of the source index tree in a logical order defined by a sequence of index keys. The logical order can be different from a physical order of the source leaf pages defined by a sequence of respective storage locations. The backup process constructs target leaf pages of the target index tree maintaining the logical order. A restore process constructs target non-leaf pages of the target index tree based on the distribution of the index keys among the constructed leaf pages and stores the target leaf and non-leaf pages.
摘要翻译：根据本发明的实施例，提供了一种用于重组数据库表的源索引树的方法，其导致数据库表的目标索引树。备份过程按照索引键序列定义的逻辑顺序读取源索引树的源页面页面。逻辑顺序可以不同于由各个存储位置的序列定义的源叶子页的物理顺序。备份过程构建维护逻辑顺序的目标索引树的目标叶页面。恢复过程基于构建的叶子页面中的索引关键字的分布来构建目标索引树的目标非叶子页面，并存储目标叶子和非叶子页面。
