Abstract: Modeling non-functional requirements (NFRs) in a computer programming environment. In one aspect, this further comprises: identifying use case (UC) artifacts having one or more NFRs; retrieving the one or more NFRs and any data associated therewith; analysing the associated data to define a test case therefor; retrieving a UC realisation from a model to determine one or more possible program flows; and testing each possible program flow to select the test case which verifies the use case required, thereby modeling the NFR.

Abstract: A method, system and computer program product for administering a secure data repository. Rather than using a specific database, an application may use an existing hierarchical file structure, such as provided by conventional operating systems, to store structured data in a number of files. To detect unauthorized, malicious or inadvertent changes to these files, either within one or more files, or by deletion, replacement or movement of files in their entirety, each file incorporates a last change timestamp and the contents of the file are digitally signed. Furthermore, every file in the secure repository is logged in an index file together with its respective change date stamp, and the index file as a whole is also digitally signed. Unauthorized changes can be identified by comparison of the file date stamps with the content of the index as well as verifying the validity of each digital signature.

Abstract: A heterogeneous environment having applications and application enablers operating on application servers organized as a cluster is managed. The application servers are managed by a cluster management application. A system management application permits access to computing performance data provided by an operating system and reported to the system management application. Performance data of the applications and application enablers is collected from an application agent through the application servers. Topology information regarding the application servers is collected via the cluster management application. The performance data and the topology information are retrieved and sent to the system management application. Access to the performance data via the system management application is permitted. The system management application links to the computing performance data using the topology information.

Abstract: Communication device capabilities may change during an established multimedia session due to connection of a peripheral device. For example, a user listens to an Internet radio service on a mobile phone through a set of headphones. Later, the user connects the mobile phone to stereo system in a car. The mobile phone can leverage the car's stereo system to present higher quality audio than it could present with the headphones. Functionality can be implemented in a communication device to detect connection of a peripheral device and determine multimedia capabilities of the peripheral device. The communication device updates its presence information to indicate the multimedia capabilities of the peripheral device. In response, a multimedia server determines multimedia capabilities indicated in the presence information have changed and optimizes delivery of multimedia content based on the updated multimedia capabilities.

Abstract: A mechanism is provided to detect that a dynamic migration of a virtual environment is in progress or has been executed during a hardware or software scan without requiring instrumentation of applications running within the virtual machine. The mechanism relies on a particular sequencing and usage of application programming interfaces and commands that scanning technology provides, associated with the modularity of the scans and on the external virtual machine enabler component running on the host. The mechanism may detect a dynamic migration and take proper actions based on the system configuration. The actions may include discarding the output of the scan executed across a dynamic migration and repeat the scan. The actions may also include notifying the initialization subsystem of the non-migration-safe application to execute a script or program to address migration safety issues. One particular program or script may be an agent ID regeneration program or script.

Abstract: For routing information in a network across firewalls, virtual sessions between two remote nodes are implemented by means of multiple point-to-point sessions between pairs of adjacent nodes connected through a tunnel crossing the corresponding firewall. Each node stores a routing table that is used to pass the information to be provided to a desired target node to the correct adjacent node. A peer-to-peer communication scheme is supported for allowing each pair of nodes to exchange information. For this purpose, a specific algorithm is proposed for propagating the routing information dynamically among the nodes of the network, with rules that prevent the generation of any propagation cycle.

Abstract: A system and method for focused and scalable event enrichment for information management system service models in which a monitoring agent monitors one or more IT components running on one or more end-points. When an event probe is installed, a local metadata cache is primed with metadata stored on a metadata server. After a monitoring agent receives an event from an end-point, the event is enriched with metadata stored in the local metadata cache. The enriched event is then uploaded to an event monitoring server. A business service manager server uses the enriched events stored on the event monitoring server to manage the service model and to quickly determine service status based on service impacting events.

Abstract: The compliance of a virtual machine image to a set of requirements is determined during a process to potentially introduce the virtual machine image into a network. One or more virtual machine images are identified. During compliance testing, the identified virtual machine image is controlled such that it cannot connect to the network. One or more tests are carried out to determine if the virtual machine image is compliant with one or more predetermined requirements. If a virtual machine is compliant with said one or more predetermined requirements, the virtual machine image is connected to the network.

Abstract: An incompatibility problem during a virtual environment migration from a first host to a second host can be addressed by changing a configuration of the virtual environment and/or by migrating the virtual environment to a host other than the second host. A migration advisor module is configured to take such action automatically upon detection of the incompatibility problem. Alternatively, the migration advisor module may take such action with assistance and/or input from an operator. The migration advisor module can change the configuration of the virtual environment by removing unnecessary components of the virtual environment and causing the reconfigured virtual environment to be migrated to the second host. Alternatively, the migration advisor module can cause the virtual environment to be migrated to a third host with sufficient physical system resources to meet the requirements of the virtual environment.
