摘要： Described herein are techniques for time limited lock ownership. In one embodiment, in response to receiving a request for a lock on a shared resource, the lock is granted and a lock lease period associated with the lock is established. Then, in response to determining that the lock lease period has expired, one or more lock lease expiration procedures are performed. In many cases, the time limited lock ownership may prevent system hanging, timely detect system deadlocks, and/or improve overall performance of the database.
摘要翻译：这里描述的是用于限时锁定所有权的技术。在一个实施例中，响应于接收到对共享资源的锁定的请求，该锁被授予并且与该锁相关联的锁租约期间被建立。然后，响应于确定锁租约期已经过期，执行一个或多个锁租约期过程。在许多情况下，限时锁定所有权可能会阻止系统挂起，及时检测系统死锁，和/或提高数据库的整体性能。

摘要： Locks are placed in a convert queue in a way that compensates for queue bias. Rather than always placing a remote lock in a queue at the tail, a remote lock can be placed further up in the queue, and possibly be interleaved with local locks. As a result, remote processes are granted locks more frequently and swiftly. Locks are placed in a convert queue according based on queue placement factors, which are factors accounted for when placing a lock in a queue.
摘要翻译：锁定以一种补偿队列偏差的方式放置在转换队列中。而不是总是将远程锁放置在尾部的队列中，远程锁可以进一步放置在队列中，并且可能与本地锁交错。因此，远程进程被更频繁和迅速地被授予锁定。根据队列放置因子将锁放置在转换队列中，这些因素是将锁放置在队列中时考虑的因素。

摘要： Systems, methods, and other embodiments associated with producing a proximity display of correlated load metrics associated with members of a cluster are described. One example method includes acquiring metrics data (e.g., load data) from nodes in a cluster. The example method may also include determining a cluster element state based on the metrics data and determining relationships between members of the set of related cluster elements. The method may also include identifying element metric representations for cluster elements based on cluster element states and identifying locations on a proximity display at which element metric representations are to be displayed. The locations may depend on relationships between cluster element states. The method may also include displaying element metric representations at the computed locations to produce a proximity display of correlated load metrics.

摘要： Described herein are techniques for dynamically monitoring process activeness of processes running on a computing node. Problems affecting processes to serve their designated functions on the computing node can be relatively quickly detected and dealt with, thereby making restoring process activeness on the computing node much more quickly than otherwise.

摘要： Techniques are described for storing portions of files on different storage devices based on the devices' respective storage class. For example, different extents from a large file within a system, application, or database may be stored on different storage devices. The storage devices may be part of a single storage system that includes some storage devices that have different performance capabilities. The decision of where, within the storage classes, to store data may be based on the access patterns of the data. Access patterns regarding file extents are tracked using respective access bits, which are set when a memory block associated with an extent is accessed via an I/O operation. In one embodiment, an access bitmap is modified to account for cached blocks of file extents.
摘要翻译：描述了用于基于设备的相应存储类将文件的部分存储在不同存储设备上的技术。例如，系统，应用程序或数据库中的大文件的不同范围可以存储在不同的存储设备上。存储设备可以是包括具有不同性能能力的一些存储设备的单个存储系统的一部分。在存储类中存储数据的位置的决定可以基于数据的访问模式。使用相应的访问位追踪关于文件扩展区的访问模式，当通过I / O操作访问与扩展区相关联的存储器块时，该访问位被设置。在一个实施例中，修改访问位图以考虑文件盘区的缓存块。
