A method for navigating an acyclic graph includes the steps of generating two or more acyclic graphs, each of the two or more acyclic graphs relating to a specific topology, wherein at least two of the two or more acyclic graphs include at least one common node; receiving a request to generate a composite acyclic graph, wherein the composite acyclic graph includes the at least one common node; generating the composite acyclic graph; and displaying the specific node of the composite acyclic graph.

Methods and systems for providing information a client requested about a system using scripts are described. In one embodiment, one or more scripts request information about a computer system. A translator receives the information about the system from the scripts. The translator stores the information about the system in readily accessible data structures.

The invention provides methods of placing programmatic packages in a clustered environment. An exemplary method of placing programmatic packages in response to a state change in a clustered computing system is presented including: receiving the state change; in response to receiving the state change, ordering programmatic packages, where each of the programmatic packages is configured with a package priority, the package priority representing a user designated assignment of programmatic importance from high to low; placing the programmatic package having a highest package priority on a configured node, the configured node included as part of the clustered computing system; and for each of a remaining programmatic packages, placing each of the remaining programmatic packages on a node set in accordance with a user-specified package dependency, the node set included as part of the clustered computing system.

A software application includes a document generator. A user can download from an upgrade website documentation (e.g., release notes) describing the differences in operation between a post-upgrade version of the application that would result if a target upgrade is implemented and a pre-upgrade version of the application, e.g., the one available on the user computer system. The document generator can generate full documentation for the post-upgrade version from the pre-upgrade documentation and the upgrade documentation. The post-upgrade documentation has a revision display mode and a non-revision display mode, the former showing the changes from the operation of the pre-upgrade version to the operation of the post-upgrade version.

A cluster simulator simulates reformation of a real cluster in response to failure events. Profile programs on the cluster can gather data useful to the simulation and transmit the profile data to the simulator. The simulator can generate a model of the real cluster, the model itself being a virtual cluster. A user can select virtual failure events from a menu to apply to the model and the simulator responds by generating a post-failure virtual cluster in the configuration that the real cluster would assume in the event of the corresponding real failure. Sequences of virtual failures can also be tested for a given cluster configuration to evaluate its robustness. Comprehensive testing using virtual failure sequences can also be applied to different cluster configuration so that an optimum configuration can be recommended.

A method, and a corresponding apparatus, implemented on a suitably programmed processor, selects an ideal computer to remove from a computer cluster observing a failure condition. The computer cluster includes multiple computers. The method includes the steps of recording, at each of the computers, health data for each of the computers, computing, at a health timeout, a first health score for each of the computers based on the health data, computing, at a fatal timeout, and based on the first health score, a second health score for each of the computers, and at each of the computers, selecting a computer having the highest health score for removal from the cluster.
摘要:
Mechanism for displaying a layout of graphic user interface properties in a panel. The data is stored in managed object format (MOF) files and defines how the data to be displayed is interrelated. The generic mechanism defines the layout of interrelated object properties, where the layout of similar panels appear differently based on the type of the object of focus. An object is associated with a defined set of properties that may correspond to properties of other objects, as well. The system isolates information that determines the look and feel of status and property layout displays of a GUI into one file. This file can be quickly edited to change the appearance when needed. The application source code utilizes a class schema and the modifiable file is read in and processed when the application is launched. Further changes require the application to be restarted to read in the modified file.
