According to one aspect of the present invention, a method for updating firmware associated with a memory storage device includes providing new firmware to a host and sending the new firmware from the host to a reader which communicates with the host. The reader interfaces with the memory storage device which includes installed firmware. The method also includes sending the new firmware from the reader to the memory storage device, and incorporating the new firmware into the memory storage device such that the new firmware at least partially replaces the installed firmware. In one embodiment, the method further includes embedding the new firmware into a first command. In such an embodiment, sending the new firmware from the host to the reader includes sending the first command from the host to the reader.

Abstract: The invention is directed to techniques for selecting a resource from several resources to process a request from a client. A client sends the request to a data communications device (e.g., network device or switch), which measures usage information from usage meters associated with each resource (e.g., server). The data communications device then makes a usage estimate for each server of the increase in usage required for that server to process the request from the client. Then the data communications device selects one of the servers depending on the usage estimates required to respond to the client's request. The data communications device can consider other factors such as the current level of usage, past usage, and the increased cost of responding to the request. In addition, the data communications device can consider the peak usage level of each resource already established in a current billing period.

Abstract: A method of installing a mobile program code for the control of an industrial automation system with a central computer and a plurality of actors and sensors coupled via a bus system with said central installation computer, has the steps of transmitting the mobile program code from a remote location to the central computer of the industrial automation system, installing and commissioning the mobile program code independently on the industrial automation system, and generating by means of the mobile program code further mobile program codes having a defined task, and transmitting the further mobile program codes at least to said actors and sensors within the industrial automation system.

Abstract: A system and method is provided for measuring lock usage in a non-intrusive manner. Measurements are performed only when a lock is contended. When a lock is requested and the lock is available (i.e., is not contended), the only data gathered is a counter that is incremented to keep track of the number of times the particular lock was requested. When a lock is contended, an operating system trace hook is requested. The trace hook records data such as the timestamp that the requestor requested the lock, the request count, a stack traceback to identify the function corresponding to the requestor, and the address of the lock that was requested. Post-operative processing analyzes the recorded trace hook data to identify contended locks and processes that may not be efficiently using locks.

Abstract: Present herein is a system and method for arbitration in multi-threaded programming. Task calls are directed to a task wrapper that associates the task call with a particular unique identifier, and stores parameters provided by the task call at memory locations associated with the unique identifier. The execution of the task is handled by a task loop. The task loop queues a plurality of memory portions into a circular queue. The contents of the queue are serially provided to the task, and the results are serially written to the circular queue and provided back to the calling threads.

Abstract: A method, apparatus, system, and signal-bearing medium that in an embodiment determine a group associated with a command, wherein the command comprises a resource-allocating command in a logically-partitioned electronic device and determine when to perform the command based on the group. By grouping commands and scheduling the commands based on the group to which they belong, in an embodiment commands may be performed at an appropriate time when their impact on the performance of the logical partitions will be reduced.

Abstract: A system and method for developing a dynamic web page. An editor facilitates creation and modification of a web page created from static and dynamic web page code. The editor provides a source code view for accessing the dynamic code, static code and static content corresponding to the static code. The editor also provides a visual editor for accessing dynamic content generated from corresponding dynamic code. Modifications to code or content in one view are reflected in the other. A controller generates a merged model of the code and content of the web page. The merged model may be in the form of a hierarchical ordering of nodes, wherein each node corresponds to a code element or a content element. A pre-processor marks dynamic code before the code is deployed, and a post-processor un-marks the dynamic code.

Abstract: Resource management architectures implemented in computer systems to manage resources are described. In one embodiment, a general architecture includes a resource manager and multiple resource providers that support one or more resource consumers such as a system component or application. Each provider is associated with a resource and acts as the manager for the resource when interfacing with the resource manager. The resource manager arbitrates access to the resources provided by the resource providers on behalf of the consumers. A policy manager sets various policies that are used by the resource manager to allocate resources. One policy is a priority-based policy that distinguishes among which applications and/or users have priority over others to use the resources. A resource consumer creates an “activity” at the resource manager and builds one or more “configurations” that describe various sets of preferred resources required to perform the activity.

Abstract: A distributed and scalable architecture is described to facilitate reactive detection of operational state changes in diverse, heterogeneous objects, logging of detected state-changes, and generating alerts in response to detected state-changes for the purpose of remediation. Such heterogeneous objects include but are not limited to stand-alone workstations, network appliances, files and directories, as well as embedded micro-systems such as digital assistants, cellular devices, and even remotely controlled peripherals such as environmental sensors, effectors and actuators. In one embodiment, user interaction with such diverse objects is facilitated through a homogeneous user-interface metaphor through which, the rules of interaction remain constant independent of the object being monitored.
