The present invention provides a method and apparatus for processing a web page. The method comprises: identifying a plurality of source data schema elements of the web page; determining an attribute similarity between one source data schema element among the plurality of source data schema elements and one target data schema element among a plurality of target data schema elements based on attributes of the data schema elements; and mapping the source data schema element to the target data schema element for generating a target web page in response to the attribute similarity being higher than a predetermined threshold. Through this method, the data schema elements or template language elements in the web page may be transformed efficiently and conveniently, so as to transform the web page, and to enhance the transformation efficiency.

Web pages processing

A data processing method for a distributed system, the distributed system comprising a master storage node and multiple slave storage nodes, includes: storing, responsive to a request for writing a data file, multiple replications of the data file on the multiple slave storage nodes, each of the replications being segmented into data blocks of a same size, wherein the sizes of the segmented data blocks of at least two replications are different; and storing distribution information of the multiple replications.

Data processing method and apparatus for distributed systems

A computer-implemented method for collecting usage data includes running, by a computer processor, virtual firmware at least partially in a virtual hardware layer of a virtual machine. Usage data describing the virtual machine is received, at the virtual firmware and from a kernel subsystem of the virtual machine. The usage data is transmitted from the virtual firmware to a collector on a host machine that hosts the virtual machine.

Virtual machine usage data collection using securely loaded virtual firmware

In view of the characteristics of distributed applications, the present invention proposes a technical solution for applying a shared memory on an NIC comprising: a shared memory configured to provide shared storage space for a task of a distributed application, and a microcontroller. Furthermore, the present invention provides a computer device that includes the above-mentioned NIC, a method for controlling a read/write operation on a shared memory of a NIC, and a method for invoking the NIC. The use of the technical solution provided in the present invention bypasses the processing of network protocol stack, avoids the time delay introduced by the network protocol stack. The present invention does not need to perform TCP/IP encapsulation on the data packet, thus greatly saving additional packet header and packet tail overheads generated from the TCP/IP layer data encapsulation.

Controlling shared memory

A method for identifying a consumer-producer pattern in a multi-threaded application includes obtaining synchronization event data of the multi-threaded application, and identifying the consumer-producer communication pattern from the synchronization event data.

Locating bottleneck threads in multi-thread applications

A method and apparatus for discovering application configuration files in a system. The method includes the steps of: obtaining a process identifier of an application in concern; comparing the obtained process identifier with a process identifier of a process for operating configuration files in the system; and determining configuration files to be the configuration files of the application in concern if the obtained process identifier is identical to the process identifier of a process for operating the configuration files in the system. Application configuration files can be automatically discovered and thereby monitored, such that the change of the application configuration files can be effectively and accurately detected, so as to facilitate a user to perform various subsequent operations.

A method and apparatus for a native method call. The method comprises: generating, in response to a native method call-associated event, a template copy from a generic template for processing the native method call; filling information required for processing the native method call in corresponding locations in the template copy; and changing a code execution flow to execute the template copy. When a native method is called, the native method is processed by dynamically inserting the template copy in the execution path at the assembly level.

Method and apparatus for native method calls

A requesting critical wait time of a given resource may be determined. The requesting critical wait time is the time spent by the one or more resources waiting for the given resource, wherein at least one of the resources waiting for the given resource can proceed if access to the given resource is granted. A requested by critical wait time for a resource is determined, the requested by critical wait time being time spent by the resource for waiting solely for the given resource, wherein if the resource were granted access to the given resource, the resource can proceed without further waiting.

Method to compute wait time

A method and an apparatus for diagnosing memory leak. The method includes: tracing the allocation of objects; recording allocation paths and allocation time of each object; giving to each object one unique identifier (ID) corresponding to an allocation path; determining the allocation path to which each object belongs; organizing the objects which are allocated but still not collected, and counting the age generations of the objects of the similar type according to the allocation time of each object; ranking the allocation paths according to the age generations of the surviving objects; and analyzing the ranking of the allocation paths, in which the allocation path with higher rank is more probable to introduce memory leaks. Thus, the suspicious allocation path possibly incurring memory leaks is selected and reported to the user for analysis.
