Abstract: A method for processing a resource account transaction within a wireless electronic device, such as a smartphone or other portable electronic device. During or at the initiation of a resource transaction with a near-field transaction terminal, the device receives from the terminal via a first communication interface, a resource account system ID. A locally stored resource account is selectively identified based on the received resource account system ID. The device sends a resource account application ID corresponding to the selected resource account to the near-field transaction terminal via the first communication interface. From the near-field transaction terminal, the device receives a token ID that is associated with the selected resource account, and sends, the token ID to an account management system via a second communication interface. The device receives from the account management system a transaction token comprising the token ID associated with a specified transaction resource value.

Abstract: A method for processing transactions within a token transfer device, such as a smartphone or other portable electronic device. The method includes storing a transaction token having a specified transaction resource value and an associated validation parameter in the memory of the token transfer device. A transaction communication interface initiates a transaction service with a token recipient terminal and invokes a token state manager. The token state manager determines an event corresponding to the specified validation parameter by determining a transaction resource network connect activity status and by determining condition register data associated with the validation parameter. The token state manager then issues a transaction modification call based on the determined event and the validation parameter.

Abstract: Near cache distribution in in-memory data grid environment that utilizes manifest of keys may be provided. An application instance may be initialized that utilizes an in-memory data grid caching infrastructure with a near cache in a virtual machine running on hardware processor. The near cache for the application instance may be activated. Logic of the near cache associated with the application instance may request a manifest of keys from one or more peer applications utilizing the in-memory data grid caching infrastructure, and receive the manifest of keys. The logic of the near cache associated with the application instance may send the manifest of keys to a grid cache of the in-memory data grid caching infrastructure. The logic of the near cache associated with the application instance may receive at least some of the data objects from the grid cache.

Abstract: Aspects of the present invention provide an approach that evaluates a locally running image (e.g., such as that for a virtual machine (VM)) and determines if that image could run more efficiently and/or more effectively in an alternate computing environment (e.g., a cloud computing environment). Specifically, embodiments of the present invention evaluate the local (existing/target) image's actual and perceived performance, as well as the anticipated/potential performance if the image were to be migrated to an alternate environment. The anticipated/potential performance can be measured based on another image that is similar to the existing/target image but where that image is running in a different computing environment. Regardless, the system would display a recommendation to the end user if it were determined that the image could perform better in the alternate environment (or vice versa).

Abstract: Embodiments of the present invention provide a method, system and computer program product for analytics driven IMDG cache hydration. In an embodiment of the invention, a method of analytics driven IMDG cache hydration includes retrieving from an analytics engine data utilization metrics for data in a database of a DBMS, selecting a subset of the data according to the data utilization metrics, and hydrating an IMDG cache of the DBMS with the selected subset. In one aspect of the embodiment, the data utilization metrics indicate one of a frequency and a recency of retrieval of the data in the database. In another aspect of the embodiment, the method additionally includes adding subsequent data to the IMDG cache when the subsequent data has been requested for retrieval a threshold number of times.

Abstract: A method, system and computer program product for autonomic caching in an IMDG has been provided. A method for autonomic caching in an IMDG includes receiving from a client of the IMDG a request for a primary query in the IMDG. The method also includes associating the primary query with a previously requested sub-query related to the primary query. Finally, the method includes directing the sub-query concurrently with a directing of the primary query without waiting to receive a request for the sub-query from the client. In this way, the method can proactively predict a receipt of the request for a sub-query following a request for a primary query prior the actual receipt of the request for the sub-query.
