A server monitors receipt of application access requests for application asset data from client devices. Each client device includes a local cache and the server includes a back-end cache. In response to receipt of each application access request, a number of client devices requesting access to the application asset data and an access privilege type requested by each requesting client device are determined. The application asset data is migrated between the back-end cache and at least one local cache based upon the determined number of client devices requesting access to the application asset data and the access privilege type requested by each requesting client device.

A state machine program is generated from a state machine. The state machine has states, transitions and events. A basic structure for the state machine program is generated. The basic structure has therein a structure that operates in non-final states. A statement is generated within the structure for detecting an event. A statement is generated within the structure for evaluating the detected event based on a current state to identify if the current state is valid for the detected event. A statement is generated within the structure for determining a next state if the current state is valid. A statement is generated within the structure for transitioning the current state to the next state.

A BPEL program simulator can include a document object modeler configured to arrange activities defined by a BPEL document into a document object model (DOM) tree. The DOM tree can include activity nodes and links between the activity nodes. The BPEL program simulator further can include simulation logic configured to process the activity nodes to emulate at least one BPEL activity selected from the group consisting of Sequence, Flow, While, Pick and OnMessage, Switch and Case, Invoke, Script, Receive, Reply, Empty, Staff, and Assign.

Business process execution language program simulation

A method, system and apparatus for applying virtual threads in debugging a business process program. In accordance with the present invention, different activities in a business process can be associated with corresponding virtual thread identifiers where groups of the activities related to one another through corresponding links can be assigned a single virtual thread identifier. Based upon the association of activities with corresponding virtual thread identifiers, a directed graph of different activities of different virtual thread identifiers can be generated. Accordingly, debug operations including applying breakpoints, step over debugging and the like can be applied to a business process program regardless of the host platform for any one activity in the business process program.

Virtual threads in business process programs

A method, system and computer-readable storage for breakpoint management and reconciliation for business integration language specified programs is disclosed. The system includes a business integration language development environment including BPEL development environment cooperatively coupled to a BPEL engine; debug tooling accessible through the environment; and breakpoint management and reconciliation processor coupled to the debug tooling. The debug tooling comprises script display for displaying textual portions of script embedded in source code of a business integration language specified program, and at least one other display selected from a graphical process flow display, a debug display and a breakpoint module display. The breakpoint management and reconciliation processor manages establishing of symbolic breakpoints in the source code and reconciling corresponding breakpoints in an operable form of the source code. The script module display visually demarcates a location in the source code on reconciling its corresponding breakpoint to an encountered breakpoint.

Disclosed herein is a welding helmet, comprising a face-protecting shroud, the shroud having an aperture, the shroud including a filter for protecting an operator from potentially damaging radiant energy being emitted from a workpiece, the filter providing a first viewing region through which the operator may safely view the workpiece during activities generating potentially damaging radiant energy, and a second viewing region adjacent the first viewing region for viewing the workpiece during activities not generating potentially damaging radiant energy, thereby allowing the operator to view the workpiece through either one of the viewing areas without the need to remove the welding helmet.
