International Classification:

G06F 17/00

US Classification:

707203, 707100, 707102, 707204

Abstract:

A method for hosting versioned web services includes steps of: receiving a request from a service requester, the request comprising version metadata; parsing the request; extracting the version metadata from the parsing step; and locating a target implementation version using the version metadata. If the target implementation version is located, the method proceeds by dynamically routing the versioned request to the target implementation version.

US Classification:

709223, 709203, 709219

Abstract:

A method for managing a web service client update without recompiling or redeploying of the client code includes the following steps or acts of: receiving a request for the web service from a subscribed client; transmitting the request to the web service; receiving notification of the web service update from a service provider or registry or some other means; parsing the notification and retrieving parameters describing the web service update; marshalling the parameters; determining whether the new web service update is compatible with the current web service invoked by the client application; updating the local service proxy instance with the marshaled parameters if the new web service update is compatible with the current web service invoked by the client application; and transmitting a notification if the web service update is not compatible with the current web service invoked by the client application.

US Classification:

709203, 707695, 709224, 709226, 709238

Abstract:

A method for hosting one or more versions of a service using a service proxy includes specifying an interface definition of a service which defines and uniquely identifies an interface version for the service, and an implementation definition of the service which uniquely identifies an implementation version for the service; generating one or more service proxies each representing an interface version of a service; providing a proxy configuration that contains entries for a plurality of service implementation versions, wherein each proxy utilizes the proxy configuration to access a certain one or more of the implementation versions which share the same or a compatible interface version of a service, and wherein the proxy configuration contains attributes that include information about each of the implementation versions; and wherein the proxy dynamically selects one of the implementation versions in the proxy configuration to route one or more client service requests to based on the attributes.

Abstract:

A method for hosting versioned web services includes steps of: receiving a request from a service requestor, the request comprising version metadata; parsing the request; extracting the version metadata from the parsing step; and locating a target implementation version using the version metadata. If the target implementation version is located, the method proceeds by dynamically routing the versioned request to the target implementation version.

US Classification:

714 15, 714 381

Abstract:

According to one embodiment of the present invention, a method for business process error handling through process instance backup and recovery includes the step of creating a backup profile of selected one or more portions of a business process model at modeling stage. The method also includes the steps of deploying the backup profile into a runtime environment, and upon occurrence of an error in execution instances of the business process model, re-executing at least one of the one or more portions of the backup profile to recover from the error.

International Classification:

G06Q 10/00

US Classification:

705 727, 709201, 718100

Abstract:

A method and information processing system manage workflow instance migration. An initial workflow process model is compared with a new workflow process model. A set of differences between the initial workflow process model and the new workflow process model are determined. At least one set of activities associated with the initial workflow process model that is migrateable to the new workflow process model is identified based on the set of differences. A migration plan associated with the initial workflow process model and the new workflow process model is generated. The migration plan includes the at least one set of activities associated with the initial workflow process model. The migration plan is then used to evaluate a set of workflow instances associated with the initial workflow process model and migrate one or more of these workflow instances to the new workflow process model based thereon.

International Classification:

H01L 29/772

US Classification:

257295, 257E29242

Abstract:

Ferroelectric semiconductor switching devices are provided, including field effect transistor (FET) devices having gate stack structures formed with a ferroelectric layer disposed between a gate contact and a thin conductive layer (“quantum conductive layer”) . The gate contact and ferroelectric layer serve to modulate an effective work function of the thin conductive layer. The thin conductive layer with the modulated work function is coupled to a semiconductor channel layer to modulate current flow through the semiconductor and achieve a steep sub-threshold slope.

International Classification:

G06Q 10/06

US Classification:

705 727

Abstract:

A method and information processing system manage workflow instance migration. A received migration plan indicates a set of workflow migration points associated with an initial workflow process model. The set of workflow migration points is associated with a set of workflow activities of the initial workflow process model. At least one workflow instance is selected from a set of workflow instances. A current migrateability state associated with the selected workflow instance is determined based at least on the set of workflow migration points. Migration of the workflow instance to a new workflow process model is granted in response to determining that the current migrateability state is set to migrateable. Migration of the workflow instance to the new workflow process model is prevented for at least a given amount of time in response to determining that the current migrateability state fails to be set to migrateable.
