Abstract: A software element database stores software element definitions according to a software element hierarchy. A score is assigned to at least one of the software element based at least in part upon the software element's hierarchy level. Further, virtual machine templates are stored in a library. The virtual machine templates include at least one software element associated with a software element from the software element database. A user enters a specification that specifies desired software elements to be included in the virtual machine via a user interface. After the specification is entered, the a score value is calculated for at least one virtual machine template from the library, based on the scores assigned to the software elements. Using the calculated score, the virtual machine template having the highest score value is selected and the selected virtual machine template is delivered as the virtual machine to a hypervisor.

Abstract: A computer method and system dynamically provide consistency of JAVA application files. A processor executed routine is configured (e.g., instrumented as an agent) to intercept each class that is loaded into a subject JAVA application or JVM. The system computes a cyclic redundancy check (CRC) of the respective JAR file surrounding the loaded class. The system compares the computed CRC value to a CRC value of at least one other copy of the respective JAR file. Based on the comparison, the system determines consistency (e.g., same version) of the multiple copies of the respective JAR file used by the subject Java application. If the multiple copies of the respective JAR file are determined to be inconsistent, the system alerts the user and/or enables the application to abort.

Abstract: Updating a plurality of computers is accomplished. A first message is created in an update source, where the first message includes a one or more instructions and an address of a message repository. The first message is transmitted to a first computer using either a Push or a Pull protocol. A second message is transmitted to the first computer using the Push or Pull protocol, the second message comprising data retrieved from the address in the first message. The first computer executes one or more of the instructions in the first message with at least some of the second message. The address in the first message is updated to match the address of the first computer. The updated first message is transmitting to a further one of the computers. Transmission of the second message is repeated to further ones in the plurality of computers until all of the plurality of computers have been updated.

Abstract: The invention provides a method and system for testing a software component, by instrumenting the software component under test with a component able to modify the execution of the component under test and able to generate an event corresponding to the performed modification, and by verifying that the order and the content of the event received match a predefined sequence.

Abstract: A software patch management solution (200) is proposed. The devised solution is based on the idea of automating the installation of the patches through a software distribution infrastructure. For this purpose, an automation engine (225) is added to a distribution server (110). The automation engine interfaces with a patch provider (125) acting as a proxy, which stores a local copy of the patches (210) and of a patch catalogue (215) for detecting corresponding vulnerabilities. The automation engine automatically builds a distribution plan for deploying the patches to the relevant endpoints (115), according to a vulnerability catalogue (230) that stores the actual exposures of the endpoints. The distribution plan arranges the required activities in the correct order, so as to minimize the number of rebooting of the endpoints; the distribution plan ends with an activity for scanning the endpoints, so as to update the vulnerability catalogue accordingly.

Abstract: A mechanism for managing locks for one or more resources in a distributed system including multiple distributed computing nodes, is provided. One implementation involves maintaining a database as a shared storage accessible by plural participating nodes for storing shared lock information, each participating node locally managing a local list of locks, the participating nodes cooperating in providing decentralized lock management across the nodes using the local and shared lock information, to achieve granting and releasing of locks for synchronizing access to one or more resources.

Abstract: 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.

Abstract: A method, system and computer program product for optimizing memory usage of an application running on a virtual machine. A virtual machine memory block is pre-allocated and the average memory usage of the virtual machine is periodically computed using statistics collected from the virtual machine through an API. If the memory usage average becomes higher than a maximum threshold, then a recovery mode is entered by releasing the virtual machine memory block and forcing the running application to reduce its processing activity; optionally, a garbage collector cycle can be forced. If the computed memory usage average becomes lower than a minimum threshold value, which is lower than the maximum threshold value, then a normal mode is entered by re-allocating the virtual machine memory block and forcing the running application to resumes its normal processing activity. Optionally, when the virtual machine is idle, a deep garbage collection is forced.
