摘要： Techniques for managing messages in computer systems are provided. In one embodiment, in response to a publisher attempting to enqueue a message in a queue, a determination is made whether a condition is satisfied. The condition is based on the current usage of the queue by the publisher. Based on whether the condition is satisfied, a decision is made whether to enqueue the message in the queue. The decision whether to enqueue the message may comprise restricting the publisher from enqueueing any more messages in the queue until the same or a different condition is satisfied.

摘要： Described herein are various approaches that allow rules to be used to specify actions, that alleviate the complexity and burden of developing and maintaining rules in a rules-based messaging system, and that provide more efficient ways of evaluating rules. The approaches allow rules to specify user-defined transformation functions for transforming messages, to specify when and how to perform row migration, and to specify other types of actions. Rules are grouped into rule sets. Several types of rule sets, referred to as positive and negative rule sets, allow users to use rules that are less complex to develop and maintain. Rule sets are evaluated more efficiently by attempting to evaluate the rule set with less information than is needed to evaluate all the rules in the rule set. Also, the results of rules evaluations that are based on a set of values are cached for later retrieval.

摘要： In some messaging system architectures, messages can cycle back to the originator of a message, who may then propagate the message, causing the cycle to be repeated. Described herein are techniques that use rules and fields in a redo log, to manage message flows such that undesired cycles are prevented. The techniques may be used in messaging systems that have various topologies.

摘要： Techniques for grouping events in a computing system are provided. A registrant sends, to a database server, a request to register to receive a single notification based the occurrence of multiple events that satisfy certain criteria, referred to as grouping attributes. Such registrations are referred to as grouping registrations. An eventing mechanism in the database server receives and maintains grouping registrations. When an event is received, the eventing mechanism determines whether the event has been registered for in an active grouping registration, i.e., one whose start time has passed but whose completion criteria are not yet satisfied. If so, then the eventing mechanism updates grouping data associated with the grouping registration. When the completion criteria of a grouping registration are satisfied, the eventing mechanism sends a notification to the registrant and/or other intended recipient(s). The notification may provide a summary of all the events in the group or provide details about a single event from the group, such as the latest event.

摘要： A method of using a plurality of subscriber types in managing a message queue of a database management system is described and provided. The method comprises creating a subscriber with a set of rules to the message queue. The subscriber is designated as one or more of the plurality of subscriber types. Moreover, an event notification registration representing a request to be notified if a message to the message queue satisfies the set of rules may be created. In response to a new message for enqueuing to the message queue, it is determined whether the new message satisfies the set of rules. If the new message satisfies the set of rules and if so determined by a triggered event notification registration, a notification is performed according to the triggered event notification registration. A requirement that a receiver of the notification dequeue the new message from the message queue depends on the subscriber type designation.
