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.
摘要:
A system and computer program product for optimizing virtual storage in a virtual computer system including at least one virtual machine, each virtual machine being associated with one or more virtual disks. A target set of virtual machines among the virtual machines comprised in the virtual computer system is determined based on information related to the virtual machines and on shrinking constraints. For each virtual machine in the target set of virtual machines, each virtual disk associated with the virtual machine is identified. Furthermore, for each virtual disk associated with the virtual machine, the following occurs: the virtual disk is analyzed, a virtual disk saving quantity based on the virtual disk analysis is estimated, a resized virtual disk based on the estimated virtual disk saving quantity is generated, and the current virtual disk is replaced with the resized virtual disk.

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.

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.

A testing system for a reverse client-server system management program comprises a server connected to one or more recipient devices and emulating devices through one or more repeaters. The recipient devices act as targets for the management program and the emulating devices emulate one or more of the recipient devices, to enable an assessment of the scalability of the management program to a large number of targets. The repeaters direct management requests from the server to the target devices depending on the configuration of the hook and/or the nature of the operation requested by the management request. The recipient devices and emulating devices execute the required system management operation on receipt of a management request from the server (via the repeaters). The recipient devices and emulating devices generate and transmit a report detailing the outcome of the system management operation.

摘要:
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 results of 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. The comparative CRC value may be stored in a repository; and the step of comparing looks up the stored CRC value in the repository.
