A system, computer program product, and method is described to manage cloud bursting from a private cloud to a public cloud. The method starts with executing one or more software components of at least one application receiving transaction requests on at least one processing node accessing at least one database server. The one processing node is managed by at least one controller in a first deployment model of a computing infrastructure. The controller, the processing nodes and the database servers each include instrumentation for tracking of performance metrics thereof. A map is created of transaction requests received by the controller to data resources in the database by analyzing the set of common structures. The map is used to identify which of the software components and corresponding data resources in the database to move a processing node in a second deployment model of a computing infrastructure.

On-demand workload management in cloud bursting

A method and apparatus for managing remote devices. In one embodiment of the present invention, there is provided a method of managing a remote device, comprising: obtaining a first identifier based on a name sequence in state information of the remote device, the first identifier being for indicating a template that provides the state information; obtaining a second identifier based on a numerical value sequence in the state information; sending a state access notification that comprises at least the first identifier and the second identifier; and providing the state information based on the first identifier and the second identifier in response to having received a result of activating the state access notification. In one embodiment of the present invention, there is provided an apparatus for managing a remote device.

Embodiments of the present invention relate to methods and apparatuses for enabling cluster scaling. Specifically, there is disclosed a method of recording a context of configuration for an initial node of a cluster, comprising: retrieving at least one file to be used for configuring the initial node; and recording a context while configuring the initial node using the at least one file, the recorded context being information on the configuration of the initial node and to be used for enabling addition of a new node into the cluster. There is also disclosed a method of enabling addition of a new node into a cluster. Corresponding apparatuses are also disclosed. According to embodiments of the present invention, the efficiency of improving cluster scaling may be effectively improved.

Enabling cluster scaling

A method of sharing virtual machine resources. The method includes: in response to at least one user logging in to the virtual machine, monitoring file operations taken by the user in the virtual machine; recording the types of file operations; in response to the user logging out from the virtual machine, restoring the virtual machine back to the original state at the time when the user logged in to the virtual machine according to the recorded types of file operations; and in response to receiving a request for virtual machine resources, assigning one of the virtual machines which is idle and restored back to the original state to the requesting user.

Assigning restored virtual machine based on past application usage of requesting user

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.

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 concomitance scheduling a work thread and assistant threads associated with the work thread in a multi-threading processor system. The method includes: searching one or more assistant threads associated with the running of the work thread when preparing to run/schedule the work thread; running the one or more assistant threads that are searched; and running the work thread after all of the one or more assistant threads associated with the running of the work thread have run.

Concomitance scheduling commensal threads in a multi-threading computer system

A method, apparatus, and computer program product for realizing application high availability are provided. The application is installed on both a first node and a second node, the first node being used as an active node, and the second node being used as a passive node. The method includes: monitoring access operations to files by an application during its execution on the active node; replicating the monitored updates to the file by the application from the active node to a storage device accessible to the passive node if the application performs updates to a file during the access operations; sniffing the execution of the application on the active node; and switching the active node to the second node and initiating the application on the second node in response to sniffing a failure in the execution of the application on the active node.
