20140114613 | METHOD AND APPARATUS FOR DIAGNOSIS AND RECOVERY OF SYSTEM PROBLEMS - Embodiments of the present invention relate to method and apparatus for system problem diagnosis and recovery. According to embodiments of the present invention, problem symptom information in a system can be automatically monitored and collected BY a monitoring apparatus (or referred as to “agent”) deployed at the system side. Upon after receiving such information, the diagnosis apparatus, for example, may automatically determine a root cause of the problem by querying a backend knowledge repository, and possibly generate an executable software package for recovering the problem. If the diagnosis apparatus determines that the currently available information is insufficient to determine a creditable enough root cause and/or is insufficient to generate the software package for recovering the problem, the diagnosis apparatus may interactively control the monitoring apparatus to collect desired additional information. In this way, the efficiency and accuracy of problem diagnosis and recovery may be improved. | 04-24-2014 |
20140122637 | METHOD AND APPARATUS FOR PROVIDING CACHING SERVICE IN NETWORK INFRASTRUCTURE - A method and apparatus for providing caching service in network infrastructure. In an embodiment, there is provided a method for providing caching service in network infrastructure, comprising: in response to at least one application node accessing data in a storage node, caching a copy of the data in a cache server; in response to the at least one application node accessing the data in the storage node, obtaining an identifier indicating whether the data in the storage node is valid or not; and in response to the identifier indicating the data in the storage node is valid, returning the copy; wherein the at least one application node and the storage node are connected via the network infrastructure, and the cache server is coupled to a switch in the network infrastructure. In another embodiment of the present invention, there is provided an apparatus for providing caching service in network infrastructure. | 05-01-2014 |
20140181982 | METHOD AND SYSTEM FOR DATA PROTECTION - Embodiments of the present invention relate to a method and system for data protection. A data protection method comprises: receiving at least one event prediction message from at least one message source, the at least one event prediction message being associated with an event that is predicted to occur in a future period of time; analyzing information, which is relevant to the event, included in the at least one event prediction message, so as to determine a risk level of the event with respect to the data to be protected; and determining a data protection operation at least based on the risk level and a predetermined event handling policy. There is further disclosed a corresponding data protection system. According to the embodiments of the present invention, it is enabled to voluntarily, dynamically, and flexibly handle high-risk events potentially damaging data, thereby better guaranteeing data security. | 06-26-2014 |
20140189857 | METHOD, SYSTEM, AND APPARATUS FOR SECURELY OPERATING COMPUTER - The present invention provides a method, system and apparatus for securely operating a computer. The method comprises: obtaining presence status of an authenticated user, the presence status indicating whether the authenticated user is present in the vicinity of the computer; and triggering security operation in response to that the presence status indicates the authenticated user is absent in the vicinity of the computer. By means of the method, current status of an authenticated user who has logged in can be easily learned, and in turn, corresponding security operation is performed; in addition, when a user is performing sensitive operation, it can be confirmed in real time whether the user is an authenticated user who previously logged in, so that security of operating the computer is improved. | 07-03-2014 |
20140258987 | DETERMINING CORRECTNESS OF AN APPLICATION - The present invention provides a method for determining correctness of an application, comprising: obtaining a dataset and a reference running result for the application; and determining correctness of the application based on a comparison between the reference running result and an actual running result of the dataset on the application. Through the method, the users can connect to a standard task tool repository, thereby using a data-driven testing method as a complement to the existing quality assurance framework. | 09-11-2014 |
20150089309 | TROUBLESHOOTING BASED ON LOG SIMILARITY - The present disclosure relates to a method and apparatus for troubleshooting based on log similarity. In one embodiment, there is provided a method for troubleshooting based on log similarity, comprising: extracting log patterns from multiple log files in response to having collected the multiple log files from at least one system with troubles, the log pattern describing a regular expression to which a log message in a log file among the multiple log files conforms; building a pattern repository using the log patterns; mapping each of the multiple log files to an n-dimensional vector based on the pattern repository; and clustering multiple n-dimensional vectors to which each of the multiple log files is mapped into at least one group, wherein each of the at least one group indicates one trouble type of the at least one system. In another embodiment, there is provided a corresponding apparatus. | 03-26-2015 |
20150186520 | FACILITATING ACCESS TO DATA IN DISTRIBUTED STORAGE SYSTEM - Embodiments of the present disclosure relate to an apparatus and method for facilitating access to data in a distributed storage system by using a processing unit configured to collect information related to running status of the distributed storage system; obtain metadata related to data stored in the distributed storage system; in response to a request from a client, provide to the client the information related to running status and metadata related to data to be accessed; and extend storage nodes in the distributed storage system so that the client can directly access the storage nodes by using the information related to running status and the metadata related to data to be accessed. Other embodiments are also disclosed. | 07-02-2015 |
20150186907 | DATA MINING - Embodiments of the present disclosure relate to a method and apparatus for data mining by obtaining product-related data from at least one data source; preprocessing the data to determine at least one attribute of the data; analyzing the preprocessed data with respect to product-related characteristics and at least partially based on the at least one attribute; and generating an event according to the analysis and based on a predefined rule associated with the product-related characteristics, the event predicting possible customer demands. | 07-02-2015 |
20150189019 | MANAGING NETWORK ATTACHED STORAGE - A method and apparatus for managing network attached storage that includes detecting frequency of access from a client to a data item that is in a first server in the network attached storage, a global namespace of the network attached storage indicating an access address for accessing the data item, the access address including a first address of the data item in the first server; in response to the frequency being higher than a predetermined threshold, copying the data item from the first server to a second server in the network attached storage which is proximate to the client, so as to form a data image; and updating the global namespace so as to add to the access address a second address of the data image in the second server whereby the data access efficiency of the network attached storage can be considerably improved. | 07-02-2015 |
