摘要： Embodiments of the invention provide a method for regaining memory consistency after a trap via transactional memory. Transactional memory and a transactional memory log are used to undo changes made to memory from a transaction start point up to the point of a trap event. After the trap event is processed, and the changes are rolled back, the program can resume execution at the beginning of the transaction.

摘要： An ordering of operations in log records includes: performing update operations on a shared database object by a node; writing log records for the update operations into a local buffer by the node, the log records each including a local virtual timestamp; determining that a log flush to write the log records in the local buffer to a persistent storage is to be performed; in response, sending a request from the node to a log flush sequence server for a log flush sequence number; receiving the log flush sequence number by the node; inserting the log flush sequence number into the log records in the local buffer; and performing the log flush to write the log records in the local buffer to the persistent storage, where the log records written to the persistent storage comprises the local virtual timestamps and the log flush sequence number.

摘要： A memory buffer facilitates log catchup for online operations. Certain designated areas of memory are allocated for one or more buffers for use during online operations (e.g., reorganization, create index, etc.). Concurrent update activities to the target object write informational records into the one or more buffers. If the buffers become full, the informational records may be written to logs for persistent storage. After online operations finish building all or a suitable portion of the shadow object, log catchup is performed by first applying activities in the informational records from the buffer and thereafter applying activities from logs, if necessary. The invention helps solve the drawbacks of log catchup since the buffer contains only the information related to the target shadow object. Also it does not involve physical I/Os, as these records are all in memory.
摘要翻译：内存缓冲区有助于日志追踪在线操作。某些指定的存储区域被分配用于在线操作期间使用的一个或多个缓冲器（例如，重组，创建索引等）。目标对象的并发更新活动将信息记录写入一个或多个缓冲区。如果缓冲区已满，则可将信息记录写入日志以进行持久存储。在线操作完成构建阴影对象的所有或适当部分后，通过首先在缓冲区中的信息记录中应用活动，然后在必要时从日志应用活动来执行日志追踪。本发明有助于解决日志追踪的缺点，因为缓冲器仅包含与目标影子对象相关的信息。此外，它不涉及物理I / O，因为这些记录都在内存中。
