A network system includes a reconfigurable network and a network management system. The network management system can represent the network in the form of a network image. Network image objects, corresponding to network objects, can be selected as copy sources and paste targets. A copy-and-paste operation modifies the network image to indicate a potential modification of the actual network in which the configuration of the network object corresponding to the selected copy source object is applied to the network object corresponding to the selected image object. In addition, the copy-and-paste operation can automatically represent a common connection of a source object input and a target object input to a common data source. Furthermore, the copy-and-paste operation can automatically connect outputs of source and target objects to a comparison function so that the implementation of the copy-and-paste operation on the actual network can be validated.

Copy-and-paste functionality for network reconfiguration

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.

Systems and methods for placing and dragging programmatic packages in clustered computing systems

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.

Providing information about a system using scripts

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.

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.

Software documentation generation using differential upgrade documentation

A system and methods are disclosed for preventing computers in a network from concurrently processing a task, where the task can be successfully processed by only one computer in the network at a time. The system comprises a plurality of computers connected to the network and a locking device connected to the network, wherein the locking device uses a password change system to control which computer in the network is able to process the task.

Mutual exclusion lock implementation for a computer network

A system and method for handling a query seeking information about computers of a network, where the query can be optimized in a way which limits the set of computers examined to a set smaller than all known computers. The query is examined to determine a limited list of computers to be accessed that would yield the complete result. If the query can be satisfied using data from a number of computers which is less than all of the computers in the network, then the number of computers which is less than all of the computers in the network is accessed to satisfy the query. In this manner, the data collection process for satisfying the query is generally more efficient than accessing all of the computers in the network.

Method and apparatus for reducing the scope of queries that seek information from networked computers

A system and a process is provided for requesting and obtaining information about Resources on a Cluster. The system utilizes a Multiplex Provider, that may be provided on every Node of the Cluster. The Multiplex Provider facilitates the communication of requests to various Nodes without requiring Providers, at such Nodes, to be Cluster-aware and without requiring a Client to directly communicate the request to every Node. The present invention also includes a scope, specifying a range for which any request may be applied. The scope may be determined utilizing a discovery process, wherein each Node on a Cluster identifies the Providers and Resources associated with the Node. The process also entails capturing the results of a request for information in a tabular format. The tabulation may be specified to include all results of the query, unique results of the query and/or based upon any other desired tabulation.

Mechanism for nested expansion of data collection from one computer to multiple computers

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.

The present invention provides a process for providing High Availability applications on a Cluster without utilizing a fail-over mechanism. The process utilizes a first instantiation of a Package containing information needed to implement an application on a first Node of a Cluster. Additionally, the process utilizes a second instantiation of the Package on at least one second Node of the Cluster. Upon detection of a fault condition or possible fault condition in an application, a Cluster management system transfers operation of the application from the first Node to the second Node. The second Node utilizing the second instantiation of the Package to immediately implement the application without requiring the Cluster management system to fail-over the application.
