Abstract:
By ensuring that sufficient information from the buffers is maintained so that all changes of uncommitted transactions can be recreated, the storage of the undo buffers into undo logs can be minimized. Further efficiencies may be maintained by keeping a count of actions in a transaction as the actions are undone.
Abstract in simplified Chinese:本发明揭示一种在一信息设备集群中一信息设备依后端应用系统之资源利用状态处理输入异动之协商方法,包含以下步骤:接收一输入异动;依一目前临限值等级及一目前异动计数,判定是否足以处理该输入异动;及因应不足以处理该输入异动,识别一目标信息设备为协商对象。
Abstract in simplified Chinese:存在一提供用于异动处理进程记录之一系统、一方法、一进程及一系统实现方法之需要。
本发明提供一种用以基于一关于一异动处理进程之回应时间之服务等级协议来记录所运行的该异动处理进程之系统。该系统包括一记录原则表、一异动处理进程监视单元及一存储设备。该记录原则表记载一或多项记录原则,该一或多项记录原则经定义以基于该服务等级协议中所指定的一所需回应时间而用变化量之记录数据来记录一异动处理进程。该异动处理进程监视单元自动监视该异动处理进程之该回应时间。该存储设备记载一异动处理进程记录。该系统进一步包括一记录控制单元。该记录控制单元使用由该异动处理进程监视单元所监视之一异动处理进程之回应时间,以选择存储于该记录原则表中之该等记录原则之一者。根据该选定的记录原则,该记录控制单元允许该存储设备记载该异动处理进程之一记录。
Simplified title:使用动态调度合成交易以监视电子商务系统之性能及可用性之方法 METHOD FOR USING DYNAMICALLY SCHEDULED SYNTHETIC TRANSACTIONS TO MONITOR PERFORMANCE AND AVAILABILITY OF E-BUSINESS SYSTEMS
Abstract in simplified Chinese:提供一种用于监视一具有一相关联网络拓扑之指定交易服务器的操作之方法及设备。一实施例包含以下步骤:在该网络拓扑内界定复数个区域,及将一或多个监视代理进程指派至该等区域中之每一者,其中每一代理进程经调适以选择性地运行与该指定服务器之合成交易。该方法进一步包含监视由该等代理进程所运行之相继合成交易的结果,以便侦测与该等相继交易相关联之任何错误。回应于选择性地侦测到与一由该等代理进程中之一特定代理进程所运行之特定合成交易相关联的一性能或一可用性问题,动态地调度一或多个代理进程以运行合成交易,其中每一经调度交易具有与该特定交易之一指定关系。
Abstract:
A method and apparatus is provided for monitoring operations of a specified transaction server that has an associated network topology. One embodiment comprises the steps of defining a plurality of zones within the network topology, and assigning one or more monitoring agents to each of the zones, wherein each agent is adapted to selectively run synthetic transactions with the specified server. The method further comprises monitoring results of successive synthetic transactions carried out by the agents, in order to detect any errors associated with the successive transactions. In response to detecting a performance or an availability problem, selectively, that is associated with a particular synthetic transaction run by a particular one of the agents, one or more agents is dynamically scheduled to run synthetic transactions, wherein each scheduled transaction has a specified relationship with the particular transaction.
