Abstract: This disclosure provides a computer-implemented method for monitoring an application at runtime. The method comprises building up a calling relationship graph for at least one type of system method called at runtime, by checking a stack trace generated when the application is running. An application method of the application that directly or indirectly calls this type of system method is represented as a node in the calling relationship graph. The method further comprises determining one or more target nodes in the calling relationship graph by analyzing the structure of the calling relationship graph. The method further comprises inserting callback methods into application method(s) of the application corresponding to the one or more target nodes only in a calling side. The method further comprises monitoring the application at runtime by using said callback methods.

Abstract: In a field of software configuration, a technology of migrating and configuring software rapidly by determining a correspondence between device specific information and a specific configuration file location recording such information. According to one aspect of the present invention, a method for software fast configuration is provided comprising: obtaining and analyzing a software configuration program to identify a method related to the device specific information in the software configuration program; adding an identification to the device specific information obtained by the method related to the specific device information; and determining a correspondence between the device specific information and its record location in a software configuration file based on the added identification.

Abstract: A computer-implemented method for monitoring an object-oriented application is disclosed. A transaction-representative-digraph is built based upon a real-time running of the application, and the digraph contains nodes of a plurality of replaceable classes. A key node is selected based upon invocation relationships between the nodes. A monitor program is instrumented at the selected key node.

Abstract: As disclosed herein a method, executed by a computer, includes launching a session corresponding to a test environment, saving a session context to provide a saved session context, and associating the saved session context with a defect record entered in a defect tracking system. The method further includes receiving a request to recreate the test environment using the saved session context and reconnecting to a session corresponding to the saved session context, in response to receiving the request to recreate the test environment. The method further includes terminating the session corresponding to the saved session context, in response to verifying resolution of an error identified in the defect record. A computer system, and a computer program product corresponding to the method are also disclosed herein.

Abstract: The present invention relates to mechanisms for managing VM instances. More specifically, the mechanisms provide at least one VM instance in a resource pool. A configuration requirement is provided with respect to a virtual machine, the configuration requirement describing a first amount of application resources to be installed on the virtual machine. Based on the configuration requirement, a resource tree is built describing a dependency relation between the first amount of application resources. At least one VM instance corresponding to a sub-path of the resource tree is provided in the resource pool, where on each VM instance in the at least one VM instance there are installed application resources included in the sub-path.

Abstract: Embodiments of the invention relate to deploying a program module. The deploying includes obtaining a data dependency relationship between the program module and multiple to-be-deployed program modules, and a specific start order. In response to a request to install and configure the program module, data on which the program module depends are identified according to the data dependency relationship. In addition, the program module is installed and configured responsive to the identified data. The program module is started in response to completion of a startup of program modules required to be started before the program module as specified by the specific start order.

Abstract: A method and system for deploying a service in a cloud computing system. The method comprises collecting metadata information related to the service, building a list including a plurality of potential service endpoints by using the metadata information, and validating the potential service endpoints in the list. With the method, mapping between service and service endpoints is effectively processed while deploying the service.

Abstract: The present invention relates to application program logs. In particular, the invention relates to a method and a system in which an original log method of an application program is optimized and newly injected to the application program. According to one aspect of the present invention, there is provided a method for optimizing an application program log record, comprising: identifying an original log method of an application program; separating a character string parameter in the original log method into a constant part and a variable part; establishing a correspondence flag between the constant part and the variable part; constituting an optimized log method by the constant part, the variable part and the correspondence flag; and replacing the original log method with the optimized log method through a code injection. With the above method, the hard disk storage amount of the log record and the IO operation frequency can be reduced.
