摘要:
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.

摘要:
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.

摘要:
A method and apparatus for realizing application high availability. 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.

摘要:
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.
