Abstract: Architecture for efficiently ensuring that data is stored to the desired destination datastore such as for replication processes. A copy of data (e.g., messages) sent to a datastore for storage is stored at an alternate location until a received signal indicates that the storage and replication was successful. As soon as the feedback signal is received, the copy is removed from the alternate location, and hence, improves input/output (I/O) and storage patterns. The feedback mechanism can also be used for monitoring the status of data transport associated with log shipping, for example, and taking the appropriate actions when storage (e.g., replication) is not being performed properly.

Abstract: A method and apparatus for averaging out variations from run to run of a computer program are provided. With the apparatus and method, call trees are generated for two or more executions of a build of a computer program. The apparatus and method perform a “tree-addition” operation in which the two or more call trees generated during runs of the computer program are added to one another to thereby accumulate statistics for each call in the call trees. These statistics may then be divided by the number of runs whose tree data structures are being accumulated. In this way, an average of the tree data structures is generated. In addition, any portions of the tree data structure that are due to asynchronous events are averaged out so that their relative affect in the resulting tree data structure is minimized.

Abstract: A method and system for achieving highly available, fault-tolerant execution of components in a distributed computing system, without requiring the writer of these components to explicitly write code (such as entity beans or database transactions) to make component state persistent. It is achieved by converting the intrinsically non-deterministic behavior of the distributed system to a deterministic behavior, thus enabling state recovery to be achieved by advantageously efficient checkpoint-replay techniques. The method comprises: adapting the execution environment for enabling message communication amongst and between the components; automatically associating a deterministic timestamp in conjunction with a message to be communicated from a sender component to a receiver component during program execution, the timestamp representative of estimated time of arrival of the message at a receiver component. At a component, tracking state of that component during program execution, and periodically checkpointing the state in a local storage device. Upon failure of a component, the component state is restored by recovering a recent stored checkpoint and re-executing the events occurring since the last checkpoint. The system is deterministic by repeating the execution of the receiving component by processing the messages in the same order as their associated timestamp.

Abstract translation: 一种用于在分布式计算系统中实现高可用性，容错执行组件的方法和系统，而不需要这些组件的写入程序来明确地编写代码（例如实体bean或数据库事务）以使组件状态持续存在。 通过将分布式系统的本质非确定性行为转换为确定性行为来实现，从而通过有利的高效检查点重放技术实现状态恢复。 该方法包括：使执行环境适应于在组件之间和之间启用消息通信; 将确定性时间戳与在程序执行期间从发送方组件传送到接收方组件的消息相结合，该时间戳代表消息在接收器组件处的估计到达时间。 在组件中，在程序执行期间跟踪该组件的状态，并周期性地检查本地存储设备中的状态。 在组件发生故障时，通过恢复最近存储的检查点并重新执行自上次检查点以来发生的事件来恢复组件状态。 通过以与其相关联的时间戳相同的顺序处理消息来重复接收组件的执行，该系统是确定性的。

Abstract: An apparatus, system, and method are disclosed for pattern-based archiving of business events on a middleware server. The method performs pattern-based archiving of business events on a middleware server by: interpreting a user-specified naming pattern for labeling event archive structures, each event archive structure corresponding to an event; detecting the occurrence of a middleware event triggered by a business process; generating an archive filename based on the user-specified naming pattern, the filename comprising data from the event; and providing the filename to an event storage module for saving an archive file with the filename. The archiving method allows users to review archived files such that the filename provides a context for the archive document, and users can more easily find specific documents.

Abstract: A data processing method for a disk array device capable of achieving a duplex system of data and improving performance of the same device while a quantity of processing for writing into a cache memory (through a switch) is reduced. In the disk array device, a host interface portion comprises a nonvolatile memory portion for saving data written from a host computer/server, and a data transfer control portion for transferring write data from the host computer/server to the nonvolatile memory portion and a global cache memory portion. If a write request is received from the host computer/server, a data transfer control portion transfers the write data from the host computer/server to the nonvolatile memory portion and to the global cache memory portion through a switch portion.

Abstract: A system, method and computer program product are provided for generating backup sets for a specific point in time from backup data stored in a backup storage device. A backup set, in accordance with an illustrative embodiment, is a collection of the files and data that would have been the most recently backed-up version of a computer's files and data at the particular point in time if the backup set had been created at that point in time. In order to generate the backup set, versions of data objects are identified in the backup storage system that have backup timestamps equal to or prior to the designated point in time and that have deactivation times that are after the designated point in time. In addition, a mechanism for deleting versions of data objects based on a retention time and an inactive version limit is provided.

Abstract: With the purpose of achieving consistent non-synchronous copying of data from a plurality of primary side control units to a plurality of secondary side control units, all of the secondary side control units are connected via a loop, and each of the secondary side control units determines guarantee time by circulating a time added to the data received from the primary side control units via said loop communication route. A consistent data copying is guaranteed by circulating the determined guarantee time via the loop communication route.

Abstract: Systems, methods and computer program products for monitoring performance of network infrastructure and applications by automatically identifying system variables or combinations constructed from such variables that dominate variance of system performance. A method, system and computer program monitors performance of executing software applications and execution infrastructure components to detect deviations in performance. Logic acquires data from executing software applications and execution infrastructure, said data including descriptive data variables and outcomes data variables. Other logic statistically analyzes said acquired data to identify instances where the statistical description of operating behavior deviates from expected operating behavior and to indicate with a statistically significant probability that an operating anomaly exists within said executing software applications and execution infrastructure; and logic, cooperating with the logic to statistically analyze, filters out non-essential variables in the acquired data from being utilized by the logic to statistically analyze, such that remaining variables and combinations thereof account for a substantial contribution in the variance of performance of the executing software applications and execution infrastructure.

Abstract: An apparatus and method for cataloging symbolic data for use in performance analysis of computer programs is provided. The apparatus and method stores symbolic data for loaded modules during or shortly after a performance trace and utilizes the stored symbolic data when performing a performance analysis at a later time. A merged symbol file is generated for a computer program, or application, under trace. The merged symbol file contains information useful in performing symbolic resolution of address information in trace files for each instance of a module. During post processing of the trace information generated by a performance trace of a computer program, symbolic information stored in the merged symbol file is compared to the trace information stored in the trace file. The correct symbolic information in the merged symbol file for loaded modules is identified based a number of validating criteria. The correct symbolic information for the loaded modules may then be stored as an indexed database that is used to resolve address information into corresponding symbolic information when providing the trace information to a display for use by a user.
