摘要： Methods, apparatus, and computer readable medium for creating and/or editing images are disclosed. An electronic tablet device may include a display, touch sensor, a motion sensor, controller and speaker. The motion sensor may generate input signals indicative of a spatial movement of the electronic tablet device. The controller may receive the input signals and generate output signals that move a drawing tool across a canvas of the display based on the spatial movement of the electronic device. The output signals may further update the canvas to reflect an effect of moving the drawing tool across the canvas per the tilting movement.

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 transferring data items and locks associated with the data items from one node to another.
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。还提供了用于将与数据项相关联的数据项和锁从一个节点传送到另一个节点的技术。

摘要： A conflict resolution mechanism collects statistical data regarding how much time certain common actions or waits take. For example, the mechanism may collect statistics on disk I/O for each disk device. Statistics may include the average access time, for example. Such statistics may be collected over a sliding window of time. With the statistical data that the mechanism collects, the mechanism can make a more intelligent judgment regarding whether a process is in a “hanging” condition. For example, if the average I/O to a disk is 10 seconds for the past hour, and if a process is doing disk I/O to that disk for 5 seconds, then the mechanism will not yet determine that the process is hanging. In order to determine whether the process is hanging, the mechanism looks at the average time and the longest time for the particular actions that the process is performing.
摘要翻译：冲突解决机制收集关于某些常见行动或等待采取多少时间的统计数据。例如，该机制可以收集每个磁盘设备的磁盘I / O的统计信息。统计可能包括平均访问时间。这样的统计数据可以通过时间的滑动窗口收集。通过机制收集的统计数据，该机制可以对进程是否处于“挂起”状态做出更明智的判断。例如，如果磁盘的平均I / O在过去一小时内为10秒，并且如果某个进程正在对该磁盘执行5秒钟的磁盘I / O，那么该机制将不会确定该进程挂起。为了确定进程是否挂起，该机制查看进程正在执行的特定操作的平均时间和最长时间。

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： A method and apparatus for recovery a cluster database is provided. Database recovery is divided among a plurality of surviving database server instances in the cluster. A surviving instance is responsible for recovering data blocks to which the surviving instance is assigned. One form of block-to-instance assignment may be based on mastership of the blocks. If a data block is locked by a surviving instance at the time of failure, then no recovery of that data block may be necessary. Else, if a copy of a data block that is to be recovered is stored on a surviving node in the cluster, then one or more redo records are applied to that copy (if necessary). A redo record that corresponds to that data block might not need to be applied to the copy if the redo record reflects changes (to the data block) that are already reflected in the copy.
摘要翻译：提供了一种用于恢复集群数据库的方法和装置。数据库恢复在集群中的多个幸存的数据库服务器实例之间分配。幸存的实例负责恢复已分配实例的数据块。块对实例分配的一种形式可能是基于块的掌握。如果数据块在故障时由幸存的实例锁定，则不需要恢复该数据块。否则，如果要恢复的数据块的副本存储在群集中的幸存节点上，则一个或多个重做记录将应用于该副本（如有必要）。如果重做记录反映了已经反映在副本中的更改（对数据块），那么对应于该数据块的重做记录可能不需要应用于副本。

摘要： Techniques are provided for responding to the termination of a node by selecting another node, and assigning to the selected node the affinity relationships that existed between the terminated node and one or more objects. The resources that belong to the objects involved in the affinity relationships are remastered to the selected node. The selected node then performs recovery of the resources that had been opened by the terminated node and/or serves as a failover node to execute the transactions that had been executing on the terminated node.
摘要翻译：提供了通过选择另一个节点来响应终止节点的技术，并且向所选节点分配存在于终止的节点与一个或多个对象之间的亲和度关系。属于与亲和力关系相关的对象的资源将重新分配给所选节点。所选择的节点然后执行已被终止的节点打开的资源的恢复和/或用作故障切换节点来执行在终止的节点上执行的事务。

摘要： A method and apparatus for managing access to a resource using anticipatory lock conversions in a distributed lock management system is provided. According to the method, when an entity requests a lock on a resource, the entity is granted, if possible, a lock with a more restrictive lock mode than is required if it is determined that the entity may require the more restrictive lock mode in the near future.
