摘要： Techniques are described herein for handling lock-related inconsistencies. As mentioned above, such inconsistencies occur when two or more sets of lock information, relating to the same resource, convey inconsistent information about locks requested and/or granted on that resource. In general, the techniques involve causing the locally-stored lock information about a resource to be sent to the master node of the resource. The master node of the resource compares the lock information thus received against the lock information maintained by the master node. Based on the comparison, the master node determines how to resolve the lock-related inconsistency, and sends messages to those nodes that need to change their local lock information for the resource. Once all of the lock information has been made consistent, the resource made available for access. Because the lock-related inconsistency is resolved without restarting nodes, the availability required to correct the inconsistency.
摘要翻译： 本文描述了处理与锁相关的不一致性的技术。 如上所述，当与相同资源相关的两组或多组锁定信息传达关于在该资源上请求和/或授予的锁定的不一致的信息时，会发生这种不一致。 一般来说，这些技术涉及将关于资源的本地存储的锁定信息发送到资源的主节点。 资源的主节点将由此接收的锁定信息与由主节点维护的锁定信息进行比较。 基于比较，主节点确定如何解决与锁相关的不一致，并向需要更改其资源的本地锁信息的那些节点发送消息。 一旦所有的锁信息一致，该资源就可用于访问。 由于锁定相关的不一致性在不重新启动节点的情况下得到解决，所以需要更改不一致的可用性。

摘要： Techniques are provided for mastering resources by assigning resources to mastery-eligible-sets. The resources that are assigned to a mastery-eligible-set may be mastered only at nodes that belong to the mastery-eligible-set. The membership of a mastery-eligible-set for a given set of related resources may be established based on which nodes have the highest affinity for the given set of related resources. Resource usage may be monitored, and the system may be periodically reconfigured, by changing membership of the mastery-eligible-sets, based on the usage information.

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： Techniques are provided for remastering resources based on node utilization. According to one such technique, resources are remastered in response to the over-utilization of the node that currently masters those resources. The utilization of each node is tracked, and when a particular node's utilization exceeds a specified threshold, selected resources that are currently mastered by that node are remastered so that nodes other than the particular node become the new masters for the selected resources. Each node's utilization is based on that node's capacity, and each node's capacity may differ. According to an aspect of one technique, each node's capacity is based on that node's processing resources and memory resources. Remastering resources in this manner tends to reduce the average amount of time taken for nodes to handle requests for the resources that they master.
