ABSTRACT:
Method and system for locating objects in a computing grid. Requests for one or more objects are received from a client or other requesting entity. A persistent object locator is distributed across the grid and searches the grid for a reference to or handle on the requested object. The persistent object locator includes an internal object locator element (IOL) that resides locally, e.g., on the client, and an external object locator element (EOL) that resides on one or more other servers that are external relative to the client. The EOL is initiated if the IOL cannot locate the requested object locally. The EOL searches the grid for the requested object and if the object is available, delivers the reference to or handle on the requested object to the requesting entity. Objects can also be registered to the POL for future use. References to objects can also be deleted from the POL in the event of a communication failure or if a server or process terminates as expected.
