摘要:
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 realization 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.

摘要:
In an embodiment for deploying a new virtual appliance (225) on a data processing center (100) structure information of the new virtual appliance is determined (509-521). The structure information of the new virtual appliance includes an indication of the new virtual machines and an indication of the new software programs of each new virtual machine. Configuration information indicative of a current configuration of the data processing center is retrieved (527). License condition information indicative of license conditions applicable to the data processing center is also retrieved (530-533). A deployment scheme of the virtual appliance on the data processing center is then determined (539,548). The determination of the deployment scheme is performed by optimizing a cost function based on the license condition information, the configuration information and the structure information, and the new virtual appliance may be deployed (551) according to the deployment scheme.

摘要:
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.
摘要:
A software application distributed as a virtual appliance is automatically installed, updated and removed in a virtual machine system running on top of a virtual machine monitor in a computer. The software application virtual appliance comprises a virtual disk, which is automatically detected and installed or removed at the customer by a virtual disk activation manager program, which executes scripts including commands through an API to the virtual machine monitor. The virtual appliance virtual disk is also created automatically by the software manufacturing using the virtual disk activation manager program. The virtual appliance virtual disk stores the binaries of the software application, a software package created by the software manufacturer using a software package tool, an installer to execute the software package, installation and un-installation scripts and a unique identifier which is a signature for the virtual machine virtual disk.
摘要:
Predetermined multimedia services are provided to a plurality of users through a IP Multimedia Subsystem (IMS). A request is received at a placement server of a multimedia service by at least one user, and the placement server retrieves on a presence server information about the at least one user. The placement server identifies application servers including a multimedia application capable of providing the requested multimedia service, and the placement server selects an application server that is located a minimum average distance from at least one user. In response to the minimum average distance being greater than a predetermined threshold, a local application server is selected with an average distance from the user that is less than the predetermined threshold. A virtual image of the multimedia application is created on the selected local application server, and a connection is established between the user and the selected local application server.
摘要:
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.
