摘要： Techniques are described herein for returning a repository to a prior state. The repository may be, for example a database, and the prior state may be, for example the consistent state that the database had at a particular point in time in the past. When a operator-caused error has been introduced to the database by changes made by an already-committed transaction, the techniques described herein may be used to recover from the error by returning the database to a point in time prior to the commit time of the transaction that introduced the error. The techniques involve the generation of “physical undo” information, and the use of the physical undo information in conjunction with physiological undo and physiological redo to efficiently return a repository to the prior state.
摘要翻译：这里描述了将存储库返回到先前状态的技术。存储库可以是例如数据库，并且先前状态可以是例如数据库在过去的特定时间点具有的一致状态。当通过已经提交的事务所做的改变将由操作者导致的错误引入到数据库时，本文描述的技术可以用于通过将数据库返回到在提交时间之前的时间点从错误中恢复事务引入了错误。这些技术包括生成“物理撤销”信息，以及使用物理撤消信息结合生理撤消和生理重做，以有效地将存储库返回到先前状态。

摘要： A method and apparatus for creating a target database on a target platform based on a source database on a source platform is provided. A target database is created on the target platform based on data, metadata (for example, data in the system tablespace and control files), and external objects (for example, password files and externally stored tables) comprised within the source database. Data and metadata stored in tablespaces of the source database are converted to the format compatible with the target platform. The conversion of the data and metadata may be performed either at the source database or the target database. Redo information and undo information of the source database are not copied from the source database to the target database. Certain files, e.g., a password files, and links to externally stored object may be recreated on the target database.
摘要翻译：提供了一种用于在源平台上基于源数据库在目标平台上创建目标数据库的方法和装置。基于源数据库中包含的数据，元数据（例如，系统表空间和控制文件中的数据）以及外部对象（例如，密码文件和外部存储的表），在目标平台上创建目标数据库。存储在源数据库的表空间中的数据和元数据将转换为与目标平台兼容的格式。可以在源数据库或目标数据库执行数据和元数据的转换。源数据库的重做信息和撤消信息不会从源数据库复制到目标数据库。可以在目标数据库上重新创建某些文件，例如密码文件和到外部存储对象的链接。

摘要： Pieces of data are stored among storage devices based on a cycle value, which is computed for each storage device as the total capacity of all storage devices divided by the individual capacity of the storage device. Next, a storage device for a current piece of data is selected to be the storage device with the smallest key value; followed by determination of a new key value based on at least (a) the cycle value and (b) a sequence number of the current piece. After allocation, if the number of storage devices changes, reallocation is done similarly except that selection is first from a preferred set and only if the preferred set is empty then from a remainder set. Storage devices are placed in the preferred set if a piece of data would be outside a shadow (based on cycle value) of another piece pre-existing in the storage device.
摘要翻译：基于对于每个存储设备计算的周期值，存储数据的数据作为所有存储设备的总容量除以存储设备的个别容量。接下来，将用于当前数据的存储装置选择为具有最小键值的存储装置; 然后基于至少（a）周期值和（b）当前片段的序列号来确定新的键值。分配后，如果存储设备的数量发生变化，则重新分配的操作类似，除了先选择首选集，只有首选集为空，然后再从剩余集中移除。如果一条数据将在存储设备中预先存在的另一个部件的阴影（基于周期值）之外，则将存储设备放置在首选组中。

摘要： A method and apparatus identifies backup files that will restore a file in a transactional system. A reset stamp and filename is used to identify all backup files of the file having the filename since the file was last restored. A smaller number of files necessary to restore the file are selected from these backup files by sorting the list of files and selecting certain files in sort order. If necessary, earlier reset stamps are identified and more files are identified and selected, until a file is selected that contains a full backup or datafile copy of the file. For the backup files selected, information such as the location of the file is stored in the order in which the backup files are selected. The information, such as the location of each file selected, is provided in an order that is the reverse of the order in which the files were selected so that the oldest file is listed first. The files may be restored in the order provided.
摘要翻译：一种方法和装置识别将在事务系统中恢复文件的备份文件。自上次恢复文件以来，使用重置戳记和文件名来标识具有文件名的文件的所有备份文件。通过排序文件列表并按排序顺序选择某些文件，从这些备份文件中选择要还原文件所需的较少数量的文件。如有必要，可以识别早期的重置标记，并识别和选择更多的文件，直到选择了包含文件的完整备份或数据文件副本的文件。对于选择的备份文件，按照选择备份文件的顺序存储文件位置等信息。所选择的每个文件的位置等信息按照与选择文件顺序相反的顺序提供，以便最早列出文件。可以按照提供的顺序恢复文件。

摘要： Techniques are provided for managing caches in a system with multiple caches that may contain different copies of the same data item. Specifically, techniques are provided for coordinating the write-to-disk operations performed on such data items to ensure that older versions of the data item are not written over newer versions, and to reduce the amount of processing required to recover after a failure. Various approaches are provided in which a master is used to coordinate with the multiple caches to cause a data item to be written to persistent storage. Techniques are also provided for managing checkpoints associated with the caches, where the checkpoints are used to determine the position at which to begin processing recovery logs in the event of a failure.
摘要翻译：提供了用于管理具有多个高速缓存的系统中的高速缓存的技术，其可以包含相同数据项的不同副本。具体地说，提供了用于协调对这些数据项执行的写盘操作的技术，以确保数据项的较早版本不会被写入较新的版本，并且减少在故障之后恢复所需的处理量。提供了各种方法，其中使用主机与多个高速缓存进行协调以使数据项被写入持久存储器。还提供了用于管理与高速缓存相关联的检查点的技术，其中检查点用于确定在发生故障的情况下开始处理恢复日志的位置。
