摘要:
A method, apparatus and program product deallocate an object from a memory heap in a virtual machine environment by, in part, determining that the object is replaceable using an object reference associated with the object. The object may additionally be automatically determined as being properly removable by using a value indicative of a number of object references associated with the object. Where these conditions are met, the object may be removed from the memory heap. Where a new object can fit into a space within the memory from which the object was removed, the new object may be automatically allocated into the space. The object may be designated as being replaceable using automated or manual processes. A garbage collector algorithm may additionally execute, as needed.

摘要:
A method, apparatus and program product facilitate the collaborative development of an algorithm by, in part, displaying an algorithm associated with a performance attribute, and receiving user input relating to the algorithm from a plurality of networked users. The performance attribute of the algorithm may be automatically modified based on the user input. The modified performance attribute may be displayed to the plurality of networked users. A query may be received from a user interested in the algorithm. In response to the user query, the algorithm may be located from among a plurality of algorithms. For instance, the algorithm may be located from among the plurality of algorithms by matching the performance attribute to a criterion of the user query. Alternatively or additionally, the algorithm may be located by matching the performance attribute to a profile of the user submitting the user query. Also in response to the user query, a second algorithm and/or performance attribute related to the algorithm, or another, may be displayed.

A database access facility for accessing databases includes a monitoring function which monitors accesses by requesters of database data. The monitoring function tracks which database fields are requested to dynamically determine the fields which the application needs. Once sufficient tracking data is obtained, subsequent accesses to the database on behalf of an application are automatically modified by the application server to request only the fields which are likely to be needed. Preferably, the database access facility is an application server for one or middle tier applications which access the database on behalf of multiple clients in a three-tier client-server environment.

Disclosed is an apparatus, method, service product, and program product which each provide an enhanced, registration-based event handler mechanism. Listener programs are located and compiled before notification is needed. When notification is ultimately required, the pre-located listeners can be called directly without incurring the performance expense associated with first locating and then calling each listener.

摘要:
A method, storage medium, and computer that, in an embodiment, receive a command that specifies a transaction identifier, keys, and partition identifiers. A primary partition is selected that executes on a first server. The first server comprises a first grid element that includes a first row that is identified by an initial key. An identification of the first grid element, the transaction identifier, an identifier of the primary partition, and the initial key are stored in a primary factory point at the first server. A secondary partition that executes on a second server is found. The second server comprises a second grid element that includes a second row that is identified by a second key. An identification of the second grid element, the transaction identifier, an identifier of the secondary partition, and the second key are stored in a secondary factory point at the second server.
