An approach is provided for storing a snapshot of an execution image of a virtual machine (VM) instance. Based on VM, application, criticality, and change parameters, and based on a recommendation model trained on historical data about effects that changes caused by VM execution had on a capacity of a storage system that stores execution images of VM instances in first datastores, a tier is selected from multiple tiers of the storage system as the tier recommended for storing the snapshot. A datastore is selected for storing the snapshot so that the selected datastore is associated with the selected tier and selected from second datastores dedicated to storing only snapshots. The snapshot is created in the selected datastore and in the selected tier and unused space in a portion of the storage system for storing the first datastores is reduced.

Aspects provide a roadway management device having a processor configured to collect roadway attribute data associated with accidents within accident data and assign positive correlation values to roadway attributes that match the accident data. Aspects cluster subsets of the accidents that share common values of subset of the roadway attributes assigned positive correlation values; select a corrective action to obviate a one of the clustered roadway attributes; determine whether implementation of the selected corrective action has reduced occurrences of accidents matching common accident data of the clustered accidents on a relevant roadway; and increase a selection weighting value of the selected corrective action in response to determining that implementation has reduced accident occurrences. The selection weighting value is used to bias selection for implementation to obviate a roadway attributes with respect to other clustered accidents.

A method and system for generating a work breakdown structure (WBS) model data. Design model data is received. The design model data is parsed to extract WBS metadata from the design model data. A WBS template corresponding to the design model data is determined. The WBS model data is generated using the determined WBS template and the extracted WBS metadata. The WBS model data includes data entries. Each data entry is associated with a respective work task.

In an approach to determining a relative position for each computer of a group of computers within a wireless network to a computer within the wireless network, a computer receives a set of digital image files from each computer and aggregates the set of digital image files into a panoramic digital image file. The computer generates a network map depicting a position of each of the computers based on the panoramic digital image file. The computer determines a relative position map for at least one computer based on the network map and the panoramic digital image file, wherein the relative position map provides a location of each computer of the group of computers with respect to the at least one computer. The computer receives input from the at least one computer, the input using the relative position map to send data to one or more of the group of computers.

The invention discloses a method and device for automatically converting a sign and a method for automatically reading a sign. The method for automatically converting a sign comprises: disposing a first number of modules dispersedly within the sign, the first number being equal to a number of modules of a two-dimensional code that denote the sign; determining a mapping relation between the first number of modules and the respective modules of the two-dimensional code; and setting the first number of modules respectively to have same properties as the respective modules to which they are mapped of the two-dimensional code, so as to generate a converted sign. With the above method and device for automatically converting a sign, various signs can be automatically converted to machine readable signs, so that people and machines can easily understand these signs.

An architecture that allows target service interactions to be realistically simulated in a development environment. The architecture includes a proxy service, an interaction recorder, an interaction store and an emulator service. The proxy service delegates service requests received from a client component to a target service. If it is in 'record' mode, the proxy service routes any interaction data corresponding to the interaction (between the target service and the client component) to the interaction recorder. Upon receipt, the interaction recorder records the interaction data in the interaction store. Later, the proxy service can be placed in 'replay' mode so that a subsequent service request for the target service is delegated to the emulator service. Upon receipt, the emulator service retrieves the corresponding interaction data from the data store and replays the same to emulate/simulate the target service.

Method, system and program product for recording and replaying target service interaction data

Recording and replaying service interactions permits developers to evaluate, iteratively build and test middle-tier and other software components using realistic interaction data and quality of service (QoS) characteristics without requiring constant access to a resource operating in a production environment. Typical service execution sequences can be recorded once by the system administrator/deployer, then replayed as many times as necessary by developers iteratively building and testing middle-tier components.

A method, system, and data structure for implementing a workflow. The workflow divides a general work task of an enterprise into activities and associated relationships with respect to participating roles in the workflow. A checklist file is generated for each participating role. Each checklist file is stored in a first database. Each checklist file specifies activities of each participating role and at least one relationship element for each activity of each participating role. The at least one relationship element of a first activity in the checklist file of a first participating role of the participating roles includes a dependency relationship. A plurality of checklist instances is generated. Each checklist instance being stored in a second database. Each checklist instance corresponds to an associated checklist file and records a status of each activity and of each relationship element in the associated checklist.

A meta-model for creating models of alternative physical representations of logically equivalent entities, such as alternative wire format representations of logically equivalent messages, includes a logical meta-model and a physical meta-model. The logical meta-model provides logical entity component classes for creating a logical model which describes, in a platform and programming language neutral manner (e.g. as an XML schema), the logical structure of the modeled entity as a hierarchy of logical entity components. The physical meta-model provides classes for creating a physical model which describes the alternative physical representations. The physical meta-model includes Base Classes representative of generic physical representations of the logical entity components, with 'correspondence associations' being defined between the Base Classes and corresponding logical entity component classes. The physical meta-model further includes at least one set of physical representation-specific, Derived Classes descendent from the Base Classes.

In the process of hierarchical composition of software component types, the reusability of software component types is improved through the 'promotion of features'. That is, a feature of an instance of a predetermined software component type may be promoted to a software component type containing instances of the predetermined software component type. The promoted feature may then be customized when the containing software component type is instantiated.

Provided are an execution monitoring tool, a method and a computer program product for monitoring a message processing program or system. The execution monitoring tool identifies locations within the message processing program corresponding to a predefined set of execution progress stages, and inserts execution progress report generator components at these locations. Execution progress reports (including a representation of the message contents and structure) are then sent to the execution monitoring controller which maps the report data to its own representation of the program to determine the current position within an execution program. The message contents and structure, as well as the structure of the program and the current execution position, are displayed during execution on a test system. The execution reports include the current execution status as well as the position within the execution flow.
