A method, apparatus, system, and signal-bearing medium that, in an embodiment, start a timer in response to a program encountering a first breakpoint and halt the program at a second breakpoint if the timer exceeds a condition. If the timer does not exceed the condition, the program is resumed. In various embodiments, the condition may be a value retrieved from the program based on a keyword and may further include a threshold. In another embodiment, after the timer exceeds the condition an interrupt is raised and in response the program counter for the program is changed to be a specified statement. In an embodiment, a loop entry breakpoint is set at a loop entry statement in the program, a loop body breakpoint is set at a loop body statement in the program, and a loop exit breakpoint is set at a loop exit statement in the program. A timer is then started for an iteration period in response to the program encountering the loop entry breakpoint. The timer is reset to the iteration period in response to the program encountering the loop body breakpoint. The timer is canceled in response to the program encountering the loop exit breakpoint.

An apparatus, program product and method utilize automated analysis techniques to assist in the determination of acceptable usages of linguistic terms (e.g., words, phrases, acronyms, etc.). In particular, an acceptable usage of a linguistic term may be determined by scanning a plurality of documents for variants (e.g., based on differing spellings, punctuation, capitalization, meaning or definition, etc.) of the term, and tracking relative occurrences of a plurality of such variants found in the plurality of documents during scanning. By tracking occurrences of linguistic term variants, users may be able to use such statistical information to select which of the available variants represents an acceptable usage, or even a most acceptable usage, of a term. Scanned documents may be retrieved from the Internet, and scanning may occur while a user is browsing the Internet.
摘要:
A method and apparatus for monitoring the performance of a computer system with one or more active programs. A periodic sampling of the call stack is obtained. The sampled call stack is examined to infer the system performance similar to that obtained using prior art event based profiling. Embodiments also are directed to a combination approach to describing the system performance using a historical sampling to infer additional detail to fill in the gaps of the sampled data.

A method, apparatus and system for notifying a user of a portable communication device. In one embodiment, a location of a first portable communication device is determined for a first user and the location of a second portable communication device is determined for a second user. A determination is made as to whether the location of the second portable communication device is within a same region containing the first portable communication device. If the second portable communication device is within the same region as the first portable communication device, then the first user is notified of the presence of the second user.
摘要:
A portable phone is equipped with a position detector that detects the geographical position of the portable phone, and a telephone system may ring one or more land-based phones or portable phones according to the geographical position of the portable phone. One or more geographical regions are defined, with corresponding telephone parameters defined for each region. When a portable phone enters a defined region, exits a defined region, or changes between two defined regions, the function of one or more land-based phones or portable phones may change. The preferred embodiments thus allow changing the function of one or more other phones based on the self-detected geographical position of a portable phone. In this manner the convenience of using portable phones is greatly enhanced.

A method, apparatus and computer program product are provided for implementing enhanced query governor functions. Query execution includes first checking for a timeout value for a query. Responsive to identifying a timeout value for the query, an execution time for the query is reset and a monitor for each timeout value for the query is started. Then the execution of the query is started. The execution of predefined events is monitored during the execution of the query. The predefined events include a begin or end of processing of at least one of a trigger and a user defined function (UDF). Execution status of the query is periodically checked. Responsive to identifying the query is executing, checking for any expired timeout value is performed. The execution of the query is halted responsive to an identified expired timeout value.

Methods, articles of manufacture, and systems for determining a fee to be charged for requests processed in a grid computing environment based. In one embodiment the fee may be determined based on the time it takes to process a request and/or pricing schedules that may vary depending on a variety of pricing criteria. In another embodiment, a completion time criterion that defines a maximum acceptable time to complete a request may be specified. If the amount of time needed to perform the request is less than the maximum acceptable time specified, returning the results may be delayed to avoid providing services valued in excess of what the customer has paid for.

An apparatus, program product, and method utilize embedded source identity information within an audio broadcast signal to facilitate the reception of the audio broadcast signal from an alternate source. Such embedded information may be used, for example, to facilitate the automated selection of an alternate source of an audio broadcast signal, e.g., in response to poor reception of the primary source of the audio broadcast signal, so that a listener is less likely to miss any portion of an audio broadcast. In one particular implementation, an audio broadcast signal is a radio signal broadcast by a radio station, whereby suitable alternate sources might include another radio station that broadcasts the audio broadcast signal over a different frequency, a transmission device accessible over a telephone network, or a transmission device accessible over a computer network such as the Internet.
摘要:
An apparatus and method to optimize a query access plan in a computer database system. In preferred embodiments, the query optimizer determines the query can be optimized and generates for the query an optimized access plan that eliminates records defined by a Where clause and one or more ordering criteria prior to ordering the records (sorting or grouping) and then returning a first n rows.

A program which is linked or bound by reference (referenced program) into one or more other programs supports multiple valid export signatures, each corresponding to a respective version of the referenced program. When a program is built, it records the current signature of each referenced program it is bound to. When subsequently determining whether to rebuild the program, the previously recorded signature of any referenced program is compared with all currently supported signatures of the referenced program, and only if none of the supported signatures matches does the program need to be re-built to ensure compatibility with the referenced program. Preferably, the referenced program is a program library containing supporting procedures, intended to be used by multiple applications programs which are bound to it.
